本发明涉及一种网络化文件化数字媒体节目审片方法，是一种数字电子计算机网络传输处理文件的方法，是一种用于对数字媒体节目内容进行审看处理的方法。The invention relates to a networked file-based digital media program review method, which is a method for digital electronic computer network transmission and processing files, and a method for reviewing and processing digital media program content.
背景技术Background technique
通常情况下，电视台或其它有视音频节目资料制作需求的机构，在节目制作完成后都需要由具有一定资质的人员对节目进行审看，以便确定节目内容的正确性、完整性，对节目的质量、艺术水平、文化内涵、商业效果等方面进行评价，这个审看和评价的过程称为审片。Under normal circumstances, TV stations or other organizations that need to produce video and audio program materials need to have certain qualified personnel review the program after the program is produced, in order to determine the correctness and completeness of the program content, and ensure the accuracy of the program. Quality, artistic level, cultural connotation, commercial effect and other aspects are evaluated. This review and evaluation process is called film review.
传统电视台或其它影视制作机构的节目审片过程处于一种十分原始的状态：节目制作人员完成节目制作后，把节目磁带送到审核者处。审核者采用电视台专用的录像机对节目磁带进行播放，通过监视器观看输出的画面，在播放过程中进行节目审片。审片意见通过口述或者签字的方式与节目磁带一起送还节目制作人员。由于节目审看过程中会产生修改意见，并且节目往往需要多级审看，这个过程一般需要反复多次才可以完成。The program review process of traditional TV stations or other film and television production organizations is in a very primitive state: After the program producers complete the program production, they send the program tapes to the reviewers. The reviewer uses a special video recorder for the TV station to play the program tape, watches the output screen through the monitor, and conducts program review during the playback process. The review comments shall be returned to the program production staff together with the program tape by dictation or signature. Since there will be revision opinions during the program review process, and programs often require multi-level review, this process generally needs to be repeated many times before it can be completed.
随着网络化制作系统的采用，数字媒体节目可以不再使用磁带作为载体来保存，而是作为数字媒体文件保存在网络的存储设备中，并在网络中传递。作为节目制作过程中的审片过程也开始数字化、网络化。但现在出现的数字化、网络化审片系统存在许多问题。With the adoption of the networked production system, digital media programs can no longer be stored using magnetic tape as a carrier, but stored in network storage devices as digital media files and transmitted on the network. As a program production process, the review process has also begun to be digitized and networked. However, there are many problems in the current digital and networked film review system.
节目审片系统一般由不同的网络化制作系统承建商提供，由于同一个机构可能存在多个网络化制作系统，不同的网络化制作系统的节目审片系统的实现方式、审片操作习惯等方面存在较大差异。目前已有的节目审片方法和系统有如下几种，其存在的问题描述如下：The program review system is generally provided by different network production system contractors. Since there may be multiple network production systems in the same organization, the implementation methods and operation habits of the program review systems of different network production systems There are big differences. At present, there are several methods and systems for reviewing programs, and the existing problems are described as follows:
在节目制作系统中审核编辑时间线，即对节目的某部分进行审片。一些节目大部分内容是正确的，仅仅一些关键部位需要改进，所以这种系统的审片过程十分灵活。但存在的问题是这种系统一般没有直接的节目审核的流程支持，所以节目审核过程没有流程环节的管理，这与实际节目审核流程需求不相符，不能实现多人多级别的审片处理。还有审片者必须到节目制作系统中进行审核，该系统一般部署在节目制作机房内，所以审片者必须在节目制作系统部署地点进行审片。并且因为通常在节目制作系统中审核后的编辑时间线不是最终用于播出的文件，所以无法保证审核的内容与播出的内容一致。Review the editing timeline in the program production system, that is, review a certain part of the program. Most of the content of some programs is correct, and only some key parts need to be improved, so the review process of this system is very flexible. But the problem is that this kind of system generally has no direct program review process support, so the program review process has no process link management, which does not meet the actual program review process requirements, and cannot realize multi-person and multi-level review processing. In addition, film reviewers must go to the program production system for review. This system is generally deployed in the program production room, so film reviewers must review films at the deployment location of the program production system. And because usually the edited timeline after review in the program production system is not the final file for broadcasting, it cannot be guaranteed that the reviewed content is consistent with the broadcasted content.
还有一种是使用专门的审片工作站，该工作站部署在节目制作系统内部。这种审片工作站可以审核节目成品文件，审片功能比较完备。但审片专用工作站只能由相应的网络化制作系统提供，所以跨网络化制作系统的审片基本不可能。同时这种系统也没有节目审核的流程的支持，所以节目审核过程没有流程环节的管理，这与实际节目审核流程需求不相符，不能实现多人多级别的审片处理。另外，因为节目审核系统使用的工作站一般需要访问在网络化节目制作系统的存储，所以在网络化制作系统外部署工作站进行节目审核基本不可能。Another is to use a special review workstation, which is deployed inside the program production system. This kind of film review workstation can review the finished program files, and the film review function is relatively complete. However, the dedicated workstation for film review can only be provided by the corresponding networked production system, so it is basically impossible to review films across networked production systems. At the same time, this system does not have the support of the program review process, so the program review process does not have the management of process links, which does not meet the actual program review process requirements, and cannot realize multi-person and multi-level review processing. In addition, because the workstations used in the program review system generally need to access the storage in the networked program production system, it is basically impossible to deploy workstations outside the networked production system for program review.
第三种审片系统是通过统一的流程控制系统和节目迁移系统，把节目传输到专门工作站进行审片。例如中国专利《一种视频素材远程审看方法》(申请号：200610056953.5，公开日期：2006年8月2日)。这种方法可以实现在网络化制作系统外部进行审片。但是该方法没有提供对审片流程环节的管理，其提供的节目审看过程固定且没有复杂的判断逻辑不能满足多级审看、多人审看需求，并且当需要灵活的业务流程转换时该方法无法实现。还有，因为这种方法的节目审看系统一般由节目制作系统提供，而不同厂家提供的节目制作系统差异很大，所以一般不可能为有多个节目制作系统的机构提供统一的审片操作方式。并且该方法在网络化审片时，只能支持流格式文件传输，无法满足需要同时采用多种制作格式、多种码率的要求。The third review system is to transfer programs to special workstations for review through a unified process control system and program migration system. For example, the Chinese patent "A Method for Remote Viewing of Video Material" (application number: 200610056953.5, date of publication: August 2, 2006). This method can realize the review outside the networked production system. However, this method does not provide the management of the review process. The program review process provided by it is fixed and does not have complex judgment logic, which cannot meet the requirements of multi-level review and multi-person review, and when flexible business process conversion is required Method cannot be implemented. Also, because the program review system of this method is generally provided by the program production system, and the program production systems provided by different manufacturers are very different, it is generally impossible to provide a unified review operation for organizations with multiple program production systems Way. Moreover, this method can only support stream format file transmission during network review, and cannot meet the requirements of simultaneously adopting multiple production formats and multiple bit rates.

具体实施方式Detailed ways
实施例一：Embodiment one:
在通常情况下，数字媒体节目资料在制作过程中或制作完成后需要由专人对节目的正确性、完整性、节目的质量、艺术水平、文化内涵、商业效果等等进行评价，称为审片。评价的结果可能是一组人或某个有决定权的人做出，审片的过程不是一个简单的由一个人或一组人将完成的片子从头到尾看一遍就完成的事情，而是一个复杂的过程。由于审片的过程十分复杂，审片人的专业构成也十分复杂，有的人审查节目的视频效果，有的人审查节目的音频效果，有的人审查节目的艺术质量等等，同时各个审片人对节目是否通过审查的决定权也不尽相同，有的审片人对整个节目有决定权，而有的审片人仅仅对节目是否通过有建议权，所以，各个审片人对节目的关心程度是不同的；同时整部节目在播出或发布之前是重要机密，在播出或发布之前应让尽可能少的人接触，避免机密的泄露，因此需要在审片过程中对节目进行加密保护。这就需要一定的审片规则，对审片过程进行详细的规范，既要方便审片人审看，又能保守节目内容的秘密。Under normal circumstances, digital media program materials need to be evaluated by special personnel on the correctness, completeness, quality, artistic level, cultural connotation, commercial effect, etc. of the program during or after the production is completed, which is called review. . The result of the evaluation may be made by a group of people or someone with decision-making power. The process of reviewing a film is not simply a matter of one person or a group of people watching the finished film from beginning to end. a complex process. Because the review process is very complicated, the professional composition of the reviewers is also very complicated. Some people review the video effects of the programs, some review the audio effects of the programs, and some review the artistic quality of the programs, etc. At the same time, each reviewer Filmmakers have different right to decide whether a program passes the examination. Some film reviewers have the right to decide on the entire program, while others only have the right to make suggestions on whether the program is passed. Therefore, each film reviewer has the right to At the same time, the entire program is an important secret before it is broadcast or released, and it should be contacted by as few people as possible to avoid leakage of confidentiality. Therefore, it is necessary to review the program during the review process Encryption protection. This requires certain rules for reviewing films, to regulate the process of reviewing films in detail, not only to facilitate reviewing by reviewers, but also to keep the secrets of program content.
本实施例所述的审片规则包括两个主要概念：首先是审片环节或者称为审片级别。审片可以由多个级别的审片环节组成，也可以由单个级别的审片环节组成。低级别的审片人仅仅对节目是否通过有建议权，随着级别的升高决定权的范围扩大，直至对整个节目是否可以播出或发布的决定权。其次，每个级别中是单人决定还是多人决策，如果是多人决策还要有一个综合多人意见的过程。The film review rules described in this embodiment include two main concepts: first, the film review link or called the film review level. Screening can consist of multiple levels of screening sessions, or a single level of screening sessions. Low-level film reviewers only have the right to make suggestions on whether the program is approved or not. As the level rises, the scope of decision-making power expands until the right to decide whether the entire program can be broadcast or released. Secondly, whether a decision is made by a single person or multiple people at each level, and if it is a multi-person decision, there must be a process of integrating the opinions of multiple people.
本实施例是一种网络化文件化数字媒体节目审片方法，采用一种规则引擎的设施完成规范审片规则的复杂控制过程，整个审片过程都在规则引擎的掌控之下进行。本实施可以简单的描述如下：This embodiment is a networked and documented digital media program review method, which uses a rule engine facility to complete the complex control process of standardizing review rules, and the entire review process is carried out under the control of the rule engine. This implementation can be briefly described as follows:
1.审片任务提交过程：节目制作人员在完成节目制作工作后，把制作过程中的故事板合成为节目文件，通过审片中心提供的统一数据接口或者任务提交装置，把审片任务相关的任务信息和节目文件传输到审片中心。1. Review task submission process: After the program production staff completes the program production work, they synthesize the storyboards in the production process into program files, and pass the unified data interface or task submission device provided by the review center to submit the Task information and program files are transmitted to the screening center.
2.审片任务中心处理过程：审片中心在接收到审片任务相关数据和待审节目文件后，由规则引擎进行排序处理，生成转码加密任务，转码加密系统执行完转码加密任务后，规则引擎生成分发任务，分发系统执行完分发任务后，规则引擎设置审片任务为可发布状态。2. The processing process of the review task center: after the review center receives the relevant data of the review task and the program files to be reviewed, the rule engine performs sorting and processing to generate transcoding and encryption tasks, and the transcoding and encryption system executes the transcoding and encryption tasks Afterwards, the rule engine generates distribution tasks, and after the distribution system executes the distribution tasks, the rule engine sets the review task to the publishable state.
3.审片终端任务处理过程：审片人登陆审片终端，审片终端通过查询规则引擎获得任务列表，审片人可以把自己处理的审片任务转交给其他审片人处理，同时也可以把转出的审片任务收回，审片人在审片终端系统中进行审片操作，审片终端自动把审片结果记录反馈到审片中心，审片中心把审片任务处理结果与审片任务关联，审片人可以直接在审片终端看到审片结果。3. The task processing process of the film review terminal: the film reviewer logs in to the film review terminal, and the film review terminal obtains the task list through the query rule engine, and the film reviewer can transfer the film review tasks processed by himself to other film reviewers for processing. Take back the transferred film review task, and the film reviewer performs the film review operation in the film review terminal system, and the film review terminal automatically feeds back the record of the film review result to the film review center, and the film review center compares the processing results of the film review task with the film review Task association, the reviewer can directly see the review results on the review terminal.
网络化审片业务的决策过程和工作流程都非常复杂，把实际使用过程中用到的审片规则(审核级数、审片人、审看方式、决策模式等)编辑并保存下来，通过规则引擎调用，可以很好的解决灵活定制复杂审片业务逻辑的问题。如4图所示，规则引擎主要由规则库、规则引擎核心、规则引擎接口、规则编辑器、调试工具等部分组成。The decision-making process and workflow of the networked film review business are very complicated. Edit and save the film review rules (review levels, reviewers, review methods, decision-making modes, etc.) used in the actual use process, and pass the rules Engine call can well solve the problem of flexible customization of complex movie review business logic. As shown in Figure 4, the rule engine is mainly composed of rule library, rule engine core, rule engine interface, rule editor, debugging tools and other parts.
规则库：是预先制定的审片业务规则的集合，这些规则被结构化的存储起来，形成规则库。Rule base: It is a collection of pre-established film review business rules, which are structured and stored to form a rule base.
规则引擎核心：是执行规则判定的处理核心，它包括规则管理、进程管理、规则执行器、应用调度执行器等部分，其中规则管理负责比较事实库与规则库，以决定执行哪个规则；进程负责规则执行的优先级；规则执行器负责执行规则和其他动作；应用调度执行器用于根据规则决策调用其他应用。Rule engine core: It is the processing core for executing rule judgment, which includes rule management, process management, rule executor, application scheduling executor and other parts, among which rule management is responsible for comparing the fact base and rule base to decide which rule to execute; the process is responsible for The priority of rule execution; the rule executor is responsible for executing rules and other actions; the application scheduling executor is used to call other applications according to rule decisions.
规则引擎接口：用于应用系统中集成、调用规则引擎。Rule engine interface: used to integrate and call the rule engine in the application system.
规则编辑器：规则编辑器可以对规则库中的规则条目进行人为编辑，完成规则库创建、修改、查询、删除等操作。Rule editor: The rule editor can manually edit the rule entries in the rule base to complete operations such as creating, modifying, querying, and deleting the rule base.
调试工具：用于验证规则库及执行情况的正确性。Debugging tool: used to verify the correctness of the rule base and its execution.
本实施例所述的方法使用的系统如图1所示。系统包括：制作系统的提交终端、审片中心、审片终端，所述的审片终端包括：审片手机、审片PC机、审片机顶盒；所述的审片中心包括：接收存储服务器、规则引擎、存储盘阵、转码和加密服务器、分发传送服务器，所述方法的过程如图2所示。本实施例所述节目制作系统的提交终端通常是一个节目制作网络系统的计算机终端。所述的电视机是一种带有音响设备的视音频播放设备的总称，包括各种CRT电视机、液晶电视机、等离子电视机等等。所述的手机是支持3G或WiFi功能的手机，其中安装了专门用于审片的软件，供审片人个人使用。所述的审片PC是通用微型电子计算机的简称，或者称为个人电脑，安装有通用的操作系统和专门用于审片的专业软件。所述的审片中心是由包括多个服务器、存储盘阵组成的网络系统，各个服务器和存储盘阵通过网络交换机连接。The system used in the method described in this embodiment is shown in FIG. 1 . The system includes: a submission terminal of the production system, a review center, and a review terminal. The review terminal includes: a review mobile phone, a review PC, and a review set-top box; the review center includes: a receiving storage server, A rule engine, a storage disk array, a transcoding and encryption server, and a distribution delivery server, the process of the method is shown in FIG. 2 . The submission terminal of the program production system in this embodiment is usually a computer terminal of a program production network system. The TV is a general term for video and audio playback equipment with audio equipment, including various CRT TVs, LCD TVs, plasma TVs and the like.

The film screening center is a network system composed of multiple servers and storage disk arrays, each server and storage disk array are connected through a network switch.
本实施例所述方法的过程步骤如下：The process steps of the method described in this embodiment are as follows:
提出审片申请的步骤：节目制作系统的提交终端向审片中心的接收存储服务器提出审片请求，审片中心对提出方的使用者身份进行身份识别，以确认是否为合法用户。本步骤所述“提出审片申请”的含义是由制作节目的人员通过节目制作系统提出审片的请求。而制作系统事先要与审片中心建立互相信任的关系，因此需要身份识别。身份识别包括两个方面：一个方面是提交终端是否合法，另一个方面是提交终端的使用者是否合法。通过身份识别，审片中心可以知道提出审片申请的制作系统是哪种类型的制作系统，提出审片申请的提交终端使用者是哪种节目的制作人员，以便在提供规则范本时有一定的范围。Steps of submitting application for review: The submission terminal of the program production system submits a request for review to the receiving storage server of the review center, and the review center identifies the user identity of the submitter to confirm whether it is a legal user. The meaning of "applying for review" mentioned in this step is that the program producer submits a request for review through the program production system. The production system needs to establish a mutual trust relationship with the review center in advance, so identity recognition is required. Identification includes two aspects: one is whether the submitting terminal is legal, and the other is whether the user submitting the terminal is legal. Through identity recognition, the review center can know which type of production system the application for review is, and what kind of program producer is the end user who submits the application for review, so that there is a certain degree of certainty when providing rule templates. scope.
选择审片规则的步骤：接收存储服务器确认提交终端的使用者身份后，根据该提交终端使用者的身份对规则引擎提出审片规则范本请求，规则引擎根据提交终端使用者的身份提出预先设置的几种审片规则范本供提交终端选择。如图3所示的是一种制作系统通过提交终端提交审片任务的提交界面示意图。从图中可以看出审片任务提交界面所显示的信息应当包括：节目名称、节目的ID(识别号)、栏目的名称、节目播出时间、节目时间长度、节目提交人、节目提交时间、审片规则参数。审片规则中还包括：单个审片级别或多个审片级别，每个级别环节包括：审片人的级别、层次，每个审片人是使用审片机顶盒或者审片PC机或者审片手机进行审看，是单个审片人决策，还是一组审片人审片决策等等参数，从中可以看出审片的复杂性。审片规则的确定，就是确定该规则的所有审片级别、审片人、审看方式、决策模式等参数。Steps for selecting a review rule: After the receiving storage server confirms the user identity of the submitting terminal, it requests the rule engine for a review rule template according to the identity of the submitting terminal user, and the rule engine proposes a pre-set rule template according to the submitting terminal user’s identity. There are several templates of screening rules for the submission terminal to choose from. FIG. 3 is a schematic diagram of a submission interface of a production system that submits a review task through a submission terminal. It can be seen from the figure that the information displayed on the review task submission interface should include: program name, program ID (identification number), column name, program broadcast time, program duration, program submitter, program submission time, Parameters of screening rules. Screening rules also include: a single screening level or multiple screening levels, and each level link includes: the level and level of the reviewer, whether each reviewer uses a review set-top box or a review PC or a reviewer The review by mobile phone is a single reviewer's decision, or a group of reviewers' decision-making and other parameters, from which we can see the complexity of the review. The determination of the review rules is to determine all the parameters of the rules, such as the review level, reviewers, review methods, and decision-making modes.
传输并储存的步骤：提交终端确认一种审片规则后，审片中心向提交终端反馈传输许可，提交终端向审片中心传输待审片的节目文件，审片中心接收待审片的节目文件并将待审片的节目文件存储在存储盘阵中。Steps of transmission and storage: After the submitting terminal confirms a screening rule, the screening center feeds back the transmission permission to the submitting terminal, the submitting terminal transmits the program files of the films to be reviewed to the screening center, and the screening center receives the program files of the films to be reviewed And store the program files of the films to be reviewed in the storage disk array.
提交终端确认一种审片规则后，把待审片的节目文件的路径信息传递给接收存储服务器，审片中心根据待审片的节目文件路径信息，通过FTP传输、文件拷贝或者共享路径的方式接收待审片的节目文件并将待审片的节目文件存储在存储盘阵中，同时把审片任务信息保存到接收存储服务器中。After the submission terminal confirms a review rule, it transmits the path information of the program file to be reviewed to the receiving storage server, and the review center transmits the file through FTP, file copy or share the path according to the path information of the program file to be reviewed Receive the program files of the films to be reviewed and store the program files of the films to be reviewed in the storage disk array, and save the task information of the films to be reviewed in the receiving storage server.
转码和加密的步骤：规则引擎在待审片的节目文件传输完成后，提取提交终端确认的审片规则，根据提交终端确认的审片规则中的审片人的级别和审片方式向转码和加密服务器添加转码加密任务，转码加密服务器收到转码加密任务后，根据提交终端确认的审片规则确定的码率格式需求对待审片的节目文件进行转码和加密。Steps of transcoding and encryption: After the transmission of the program files to be reviewed is completed, the rule engine extracts the review rules submitted to the terminal for confirmation, and transfers to Add transcoding and encryption tasks to the code and encryption server. After receiving the transcoding and encryption tasks, the transcoding and encryption server will transcode and encrypt the program files to be reviewed according to the code rate and format requirements determined by the review rules submitted to the terminal for confirmation.
规则引擎在获得审片任务后，根据审片任务中各级别的审片人使用的审片终端类型能够处理的节目格式参数来判断是否需要进行转码和加密。如果是首次审核且各级审片人的审片终端审核格式不一致，规则引擎就向转码和加密服务器提交第一级审核人对应审片终端需要格式节目的转码和加密任务；如果是退回重提交的审片任务，规则引擎就根据后面所有审核人对应审片终端能处理的节目格式向转码和加密服务器提交所有级别审核人对应审片终端需要格式节目的转码和加密任务。转码和加密服务器在接收到审片任务后首先会根据节目的播出时间、优先级和重要性进行智能排序，其次才会根据转码和加密服务器的当前执行任务量动态分配这些转码任务。转码和加密完成后转码和加密服务器自动把审片任务中各级别审片人对应审片终端能够处理的审片文件记录到审片任务中，以备后续流程使用。After the rule engine obtains the review task, it judges whether transcoding and encryption are required according to the program format parameters that can be processed by the review terminal type used by the reviewers at all levels in the review task. If it is the first review and the review formats of the review terminals of the reviewers at all levels are inconsistent, the rule engine will submit to the transcoding and encryption server the transcoding and encryption tasks of the first-level reviewer corresponding to the format required by the review terminal; if it is returned For re-submitted review tasks, the rule engine submits to the transcoding and encryption server the transcoding and encryption tasks of all levels of reviewers corresponding to the program formats that the review terminals can handle according to the program formats that all reviewers correspond to the review terminals. After receiving the review tasks, the transcoding and encryption server will first perform intelligent sorting according to the broadcast time, priority and importance of the programs, and then dynamically allocate these transcoding tasks according to the current task volume of the transcoding and encryption server . After the transcoding and encryption are completed, the transcoding and encryption server automatically records the review files that can be processed by reviewers at all levels corresponding to the review terminals in the review task for subsequent use in the review task.
分发传送的步骤：转码加密完成后，规则引擎按照提交终端确认的审片规则中的审片人的级别和审片方式向分发传送服务器添加分发传送任务，分发传送服务器收到分发任务后向提交终端确认的审片规则确定的审片人的审片机顶盒或者审片PC机或者审片手机推送转码加密后的待审片的节目文件。Steps of distribution and transmission: After transcoding and encryption is completed, the rule engine adds a distribution and transmission task to the distribution and transmission server according to the reviewer's level and review mode in the review rules submitted for confirmation by the terminal. After receiving the distribution task, the distribution and transmission server sends Submit the reviewer's set-top box, reviewer's PC, or reviewer's mobile phone that is determined by the screening rules confirmed by the terminal to push the transcoded and encrypted program files of the films to be reviewed.
规则引擎在获得审片任务后，根据审片任务中各级别的审片人使用的审片终端的开启状态参数来判断是否可以进行分发传送。如果存在没有开启的审片终端就先通过分发传送服务进行远程唤醒，如果唤醒失败就把审片任务暂时挂起，等审片人登陆审片终端后，规则引擎自动把审片任务激活，进行后续过程；如果存在开启的审片终端，规则引擎就根据审片终端的地址信息和对应审片文件信息向分发传送服务器提交一个向该审片终端发送对应审片文件的任务。分发传送服务器在接收到分发传送任务后，首先根据任务中的目标审片终端地址信息去联系该审片终端，如果不可以联系，就尝试远程唤醒，如果唤醒失败，就挂起该分发推送任务，如果唤醒成功就继续该分发传送任务；如果可以联系，分发服务器就根据节目的播出时间、优先级和重要性进行智能排序，再根据当前正在执行分发传送任务的状态，动态分配分发传送服务器执行该分发任务。当分发传送服务在执行任务的过程中如果发生于审片终端的通讯中断时，分发传送服务器会自动记录当前分发任务的执行进度，当分发传送服务和审片终端的通讯恢复后，分发传送服务器可以继续中断时的分发传送任务进度进行分发传送不需要从头进行分发传送。当分发传送任务完成后，分发传送服务器自动把审片任务中各级别审片人对应审片文件是否分发传送完成的状态记录到审片任务中，以备后续流程使用。After the rule engine obtains the review task, it judges whether distribution and transmission can be performed according to the opening status parameters of the review terminals used by the reviewers at all levels in the review task. If there is an unopened review terminal, it will be remotely woken up through the distribution and delivery service first. If the wake-up fails, the review task will be temporarily suspended. After the reviewer logs in to the review terminal, the rule engine will automatically activate the review task. Subsequent process: if there is an open screening terminal, the rule engine submits a task of sending the corresponding screening file to the screening terminal to the distribution server according to the address information of the screening terminal and the corresponding screening file information. After receiving the distribution and delivery task, the distribution delivery server first contacts the review terminal according to the address information of the target review terminal in the task. If it cannot be contacted, it tries to wake it up remotely. If the wake-up fails, it suspends the distribution push task. , if the wake-up is successful, the distribution and transmission task will continue; if it can be contacted, the distribution server will perform intelligent sorting according to the broadcast time, priority and importance of the program, and then dynamically allocate the distribution and transmission server according to the status of the distribution and transmission task currently being executed Execute the distribution task. When the distribution and transmission service is in the process of executing the task, if the communication between the review terminal is interrupted, the distribution and transmission server will automatically record the execution progress of the current distribution task. When the communication between the distribution and transmission service and the review terminal is restored, the distribution and transmission server will It is possible to continue the distribution and transmission task progress at the time of interruption to perform distribution and transmission without starting from the beginning. When the distribution and transmission task is completed, the distribution and transmission server automatically records the status of whether the distribution and transmission of the review files corresponding to the reviewers at each level in the review task is recorded in the review task for subsequent use in the process.
审片人身份识别的步骤：待审片的节目文件到达提交终端确认的审片人的审片终端后，使用审片机顶盒或者审片PC机的审片人将本人专用的USB密钥插入审片机顶盒或者审片PC机的USB接口，审片机顶盒或者审片PC机与规则引擎进行交互，以识别审片人身份，使用手机的审片人则使用密码与规则引擎进行交互，识别审片人身份。Steps for identifying the reviewer: after the program files to be reviewed arrive at the reviewer’s reviewer’s terminal for confirmation, the reviewer who uses the reviewer’s set-top box or reviewer’s PC inserts his own dedicated USB key into the reviewer’s The USB interface of the set-top box or the review PC, the review set-top box or the review PC interacts with the rule engine to identify the identity of the reviewer, and the reviewer using the mobile phone uses the password to interact with the rule engine to identify the reviewer person identity.
身份鉴别可以有多种方法，本步骤采用的是专用的USB密钥，即在专用的USB加密狗中烧制不可修改的用户信息，制作为专用USB密钥。使用时，持自己专用USB密钥的审片人可以将USB密钥插入审片机顶盒或者审片PC机中，审片机顶盒或者审片PC机读取USB密钥中的用户信息，然后通过与审片中心进行交互，以确认审片人的身份、级别、专业、使用权限等信息，并根据提交终端确认的审片规则，确认该审片人的合法性。Identity authentication can have multiple methods, and what this step adopts is special-purpose USB key, promptly burns unmodifiable user information in special-purpose USB dongle, makes it as special-purpose USB key. When in use, the reviewer who holds his own special USB key can insert the USB key into the review set-top box or review PC, and the review set-top box or review PC reads the user information in the USB key, and then communicates with the The film review center interacts to confirm the reviewer's identity, level, specialty, use authority and other information, and confirms the legitimacy of the reviewer according to the review rules submitted to the terminal for confirmation.
审看播放的步骤：审片机顶盒或者审片PC机确认审片人身份后，对已经储存在审片机顶盒或者审片PC机中的待审片的节目文件解密，解密后审片机顶盒通过连接的大屏幕显示器或者电视机供审片人审看。或者审片PC机通过显示器、音频设备播放待审片的节目文件的视频和音频，供审片人审看。对于使用手机审片的审片人在审片人身份确认后，由审片手机直接从分发传送服务器以流媒体方式获取待审片的节目文件并对待审片的节目文件的视频和音频通过手机显示屏、音频设备进行播放，供审片人审核。Steps for viewing and playing: After confirming the identity of the reviewer, the review set-top box or review PC decrypts the program files of the pending review stored in the review set-top box or review PC. After decryption, the review set-top box connects to the Large-screen monitors or TVs for film reviewers to review. Or the reviewing PC plays the video and audio of the program file of the film to be reviewed through the monitor and audio equipment for reviewing by the reviewer. For reviewers using mobile phones, after the reviewer's identity is confirmed, the review mobile phone will directly obtain the program files of the films to be reviewed from the distribution server through streaming media, and the video and audio of the program files to be reviewed will be passed through the mobile phone The screen and audio equipment will be played for review by reviewers.
审片的过程不仅仅是审看视频，还包括音频的审听和字幕的审看。字幕信息在转码过程中与节目的视频画面实现叠加合成；通过编解码分离转码后的视频和音频信息，进行同步解码，播放器的视频显示模块把解码出来的视频信息通过显示器、手机屏幕、大屏幕进行输出，音频信息在解码后通过播放器音频输出模块在音箱或者显示设备的声音输出设备中播放。解密过程是先通过接收存储服务器获得该加密审片文件的解密密钥，在进行视频播放过程中，播放器把获得的解密密钥和嵌入视频文件中的密钥信息进行对比，如果正确，播放器就根据解密算法把视频信息按照正常的方式进行播放，如果不正确，播放器就输出黑屏，并提示密钥非法。这样就实现了只有获得密钥才可以播放出正确画面的效果。The process of film review is not only to review the video, but also includes audio review and subtitle review. The subtitle information is superimposed and synthesized with the video screen of the program during the transcoding process; the transcoded video and audio information are separated through codec and decoded synchronously, and the video display module of the player displays the decoded video information through the monitor and the screen of the mobile phone , large screen for output, and the audio information is played in the sound output device of the speaker or the display device through the audio output module of the player after decoding. The decryption process is to first obtain the decryption key of the encrypted review file through the receiving storage server. During the video playback process, the player compares the obtained decryption key with the key information embedded in the video file. If it is correct, the playback The player will play the video information in a normal way according to the decryption algorithm. If it is incorrect, the player will output a black screen and prompt that the key is illegal. In this way, the effect that only the key is obtained can play the correct picture.
接收审片意见的步骤：审片人审看待审节目文件后，通过审片终端提出审片意见。审片终端自动把审片结果记录到审片中心，审片中心把审片任务处理结果与审片任务关联。Steps for receiving review comments: after reviewing the program files to be reviewed, the reviewer puts forward review comments through the review terminal. The film review terminal automatically records the review results to the film review center, and the film review center associates the processing results of the film review tasks with the film review tasks.
审片人审看待审文件过程中，通过审片终端提出审核意见。审核意见可以是预置的文字审核意见，可以是用户输入的审核意见，也可以是录音的审核意见。审片终端根据审片人的操作自动记录这些审核意见，在审片过程结束后，审片终端自动向审片中心的接收存储服务器传递审片任务处理结果信息，审片中心把审片任务处理结果与相关审片任务关联。同时接收存储服务器还会把审片任务处理结果信息通过外部接口传递给审片任务提交系统或者其他系统，此外还可以通过邮件、短信等方式传递给其他相关人员。In the process of reviewing the documents to be reviewed, the reviewer puts forward review opinions through the review terminal. The audit opinion can be a preset text audit opinion, an audit opinion input by a user, or a recorded audit opinion. The review terminal automatically records these review opinions according to the operation of the reviewer. After the review process is over, the review terminal automatically transmits the processing result information of the review task to the receiving storage server of the review center, and the review center processes the review task. Results are associated with related review tasks. At the same time, the receiving storage server will also transmit the review task processing result information to the review task submission system or other systems through the external interface, and can also pass it to other relevant personnel through emails, short messages, etc.
审片是否完成的判断步骤：规则引擎收到审片意见后，根据提交终端确认的审片规则判断是否达到最终审片级别，如果“是”则结束审片，如果“否”则回到“转码和加密的步骤”开始新一轮审片。Steps for judging whether the film review is completed: After the rule engine receives the film review opinion, it judges whether it has reached the final film review level according to the film review rules submitted to the terminal for confirmation. Steps of transcoding and encryption" to start a new round of film review.
接收审片意见的步骤完成后，规则引擎根据审片任务状态判断是否还有后续流程。如果审片任务处理结果中的审片任务状态不是终审，规则引擎就自动把任务状态设置为规则规定的下一级审核处理状态。如果需要进行转码和加密，就生成转码和加密任务；如果不需要，就生成分发和传送任务把审片文件送到后面级别的审片终端进行审片处理。After the step of receiving review comments is completed, the rule engine judges whether there is a follow-up process according to the status of the review task. If the review task status in the review task processing result is not final review, the rule engine will automatically set the task status to the next-level review processing status specified in the rules. If transcoding and encryption are required, generate transcoding and encryption tasks; if not, generate distribution and transmission tasks to send the review files to the review terminal at the next level for review processing.
