本发明涉及通过通信或广播配送图像的视频配送装置以及视频配送程序。The present invention relates to a video distribution device and a video distribution program for distributing images by communication or broadcasting.
本申请基于2007年8月14日在日本申请的特愿2007-211458号主张优先权，将其内容援用于本说明书。this application claims priority based on Japanese Patent Application No. 2007-211458 for which it applied to Japan on August 14, 2007, and uses the content for this specification.
背景技术Background technique
作为电视广播被广播的节目的数据中，包含视频数据和语音数据。此外，由于作为视频数据而被包含在被广播的节目数据中，因此有时包含在用户侧不能选择是否要显示的字幕(节目名或角色等的介绍，或者，海外作品中的日文字幕)。此外，被广播的节目数据中，有时包含在用户侧能够选择是否使其显示的字幕数据。这样的可选择的字幕数据一般被称为封闭字幕(ClosedCaption)，主要开发用于听力障碍者，不仅像海外作品中的日语字幕那样包括出演者的对话，还包括例如BGM或效果音等的说明。Data of programs broadcast as television broadcasts include video data and audio data. In addition, since it is included in broadcast program data as video data, subtitles (introduction of program names, characters, etc., or Japanese subtitles in overseas works) may be included which cannot be selected on the user side. In addition, subtitle data which can be selected on the user side to be displayed may be included in broadcast program data. Such optional subtitle data is generally called Closed Caption (Closed Caption), which is mainly developed for the hearing-impaired. It includes not only the dialogue of the actors like the Japanese subtitles in overseas works, but also includes explanations such as BGM and sound effects. .
例如，在NTSC(美国国家电视标准委员会：National Television SystemCommittee)方式的模拟的地面波广播中，视频信号中使用525条的扫描线，该525条中，各个场(field)(由2个场构成1个帧)的最初的21条分配用于被称为VBI(Vertical Blanking Interval：垂直消隐期间)的用于开始扫描的间隔(interval)。封闭字幕是通过对各个场的VBI中的第21条上复用字符码而被传输的。然后，使用各个场将2种字符组每秒传输约60字符。For example, in NTSC (National Television Standards Committee: National Television System Committee) analog terrestrial broadcasting, 525 scanning lines are used in video signals, and in the 525 lines, each field (field) (consisting of two fields) The first 21 entries of 1 frame) are allocated to an interval (interval) for starting scanning called VBI (Vertical Blanking Interval: Vertical Blanking Interval). Closed captions are transmitted by multiplexing character codes on entry 21 of the VBI for each field. Then, about 60 characters per second are transmitted for 2 kinds of character groups using each field.
此外，关于数字电视广播的字幕信息的传输构成为，如在国内规定即地面数字电视广播运用规定、技术资料(ARIB TR-B14)、BS/宽带CS数字广播运用规定、技术资料(ARIB TR-B15)中规定那样，能够使用字幕信息用的传输流，与视频信息的传输同时传输字幕信息。然后，在数字电视广播用接收机中，对与字幕信息对应的码进行解码，并生成构成字幕的字符、图形，从而将其叠加在视频上进行显示。在数字电视广播中有如下的技术：将使用字幕信息用的传输流与视频信息的传输同时传输的文本信息保存在内部，通过电视监视器任意时刻都能够显示阅览在内部保存的文本信息，从而即使用户不记录被显示的字幕的，也能够灵活应用字幕的信息(例如，参照专利文献1)。In addition, the transmission of subtitle information on digital TV broadcasting is composed of, for example, domestic regulations, namely, Terrestrial Digital TV Broadcasting Operation Regulations, Technical Data (ARIB TR-B14), BS/Broadband CS Digital Broadcasting Operation Regulations, Technical Data (ARIB TR-B14) As specified in B15), the subtitle information can be transmitted simultaneously with the transmission of the video information using a transport stream for subtitle information. Then, in the digital television broadcasting receiver, the code corresponding to the subtitle information is decoded to generate characters and graphics constituting the subtitle, which are superimposed on the video and displayed. In digital television broadcasting, there is a technique of internally storing text information transmitted simultaneously with transmission of video information using a transport stream for subtitle information, and displaying and viewing the internally stored text information at any time on a TV monitor, thereby Even if the user does not record subtitles to be displayed, subtitle information can be utilized (for example, refer to Patent Document 1).
近年来，电视广播能够在便携电话或PDA(个人数字助理：PersonalDigital Assistant)等用户可携带的终端中进行阅览。此外，还可以将通过家庭内的录像装置录像的节目，记录在可便携的装置中安装的记录介质中，从该记录介质再现被记录的节目。这样，被广播的字幕数据开始用于各种服务中。此外，电视广播本身也被各种装置接收，还设置能够阅览该被接收的节目的结构。In recent years, television broadcasts have been viewed on portable terminals such as mobile phones and PDAs (Personal Digital Assistants). In addition, it is also possible to record a program recorded by a recording device at home on a recording medium installed in a portable device, and to reproduce the recorded program from the recording medium. In this way, broadcast subtitle data comes to be used in various services. In addition, television broadcasting itself is also received by various devices, and a configuration is provided in which the received programs can be browsed.
但是，虽然电视广播被各种装置接收，通过该电视广播被广播的节目，记录在规定的记录介质中，在可便携的装置中进行阅览等，但记录该节目的记录介质的容量有限。此外，若附加可安装(可内置)在可便携的装置的记录介质这一条件，则可利用的记录介质的容量进一步被限定。However, although TV broadcasts are received by various devices, and programs broadcast by the TV broadcasts are recorded on predetermined recording media and viewed on portable devices, the capacity of the recording media on which the programs are recorded is limited. Furthermore, if a recording medium that can be mounted (built-in) in a portable device is added, the capacity of the recording medium that can be used is further limited.
因此，若在可便携的装置中阅览节目，则只能阅览短时间的节目(只能阅览节目的一部分)，若为了记录长时间的节目而提高压缩率，则存在视频粗糙且画质降低的问题。还存在因此而不普及的问题。因此，期待在可便携的装置中也能够阅览长时间的节目和多个节目，且能够防止画质降低而进行阅览的功能。Therefore, if you browse programs on a portable device, you can only browse a short program (only a part of the program can be viewed), and if you increase the compression rate to record a long program, the video will be rough and the image quality will be reduced. question. There is also the problem of not being popular because of this. Therefore, there is a demand for a function that allows viewing of long-time programs and multiple programs, and prevents image quality from deteriorating, even on portable devices.
为了解决这样的问题，公开了如下的信息处理装置中：在可便携的装置中，为了能够阅览多个节目或长时间的节目，对由便携电话机指示的电视广播的节目进行录像，将该被录像的节目变换为通过时刻信息相关联的缩略图图像数据和文本数据而进行显示，从而能够掌握节目的内容(例如，参照专利文献2)。In order to solve such a problem, an information processing device is disclosed in which, in a portable device, in order to be able to browse a plurality of programs or a long-time program, a program of a television broadcast instructed by a mobile phone is recorded, and the A recorded program is converted into thumbnail image data and text data associated with time information and displayed so that the content of the program can be grasped (for example, refer to Patent Document 2).

接着，参照图5，说明在从进行阅览、检索的显示画面至进行视频、声音的视听的显示画面的切换中，提高对于操作的响应性，降低对用户带来的等待时间的压力的其他的视频配送动作。图5是表示从图1所示的配送装置1对接收装置23配送视频的动作的流程图。首先，配送装置1的缩略图/静止图像/低分辨率、低速活动图像生成单元48生成缩略图和高分辨率的静止图像，作为伴随视频数据的数据，并将其记录在存储单元4中(步骤S80)。Next, with reference to FIG. 5 , in switching from a display screen for browsing and searching to a display screen for viewing video and audio, other methods for improving responsiveness to operations and reducing the pressure on the user's waiting time will be described. Video delivery action. FIG. 5 is a flowchart showing the operation of video distribution from the
然后，配送装置1的缩略图/静止图像/低分辨率、低速活动图像生成单元48生成高分辨率且低帧速度的活动图像，作为伴随视频数据的数据，并将其记录在存储单元4(步骤S81)。Then, the thumbnail/still image/low-resolution, low-speed moving image generation unit 48 of the
然后，配送装置1的缩略图/静止图像/低分辨率、低速活动图像生成单元48生成低分辨率且高帧速度的活动图像，作为伴随视频数据的数据，并将其记录在存储单元4(步骤S82)。Then, the thumbnail image/still image/low-resolution, low-speed moving image generation unit 48 of the
另外，这里说明了缩略图/静止图像/低分辨率、低速活动图像生成单元48按照步骤S80、S81、S82的顺序进行处理的情况，但并不限定于此，步骤S80、S81、S82的处理可以按照任意的顺序进行。此外，也可不进行S81、S82、S83的处理。In addition, the case where the thumbnail image/still image/low-resolution, low-speed moving image generation unit 48 performs processing in the order of steps S80, S81, and S82 has been described here, but it is not limited thereto. The processing of steps S80, S81, and S82 Can be done in any order. In addition, the processes of S81, S82, and S83 may not be performed.
然后，文本/缩略图配送单元5根据来自接收装置23的请求，通过通信单元8对接收装置23发送缩略图(缩小静止图像)和伴随各个缩略图的文本信息(字幕信息)(步骤S31)。接收其，接收装置23通过接收经由通信单元27从配送装置1发送的缩略图和文本的信息，并存储在存储单元28，从而作为该缩略图和文本的信息内容数据40来持有(步骤S52)。在该时间点，视频(活动图像)数据43和声音数据44并不存储在存储单元28中，仅存储文本数据45和缩略图数据46。Then, the text/thumbnail image distribution unit 5 transmits thumbnails (reduced still images) and text information (subtitle information) accompanying each thumbnail to the receiving device 23 via the communication unit 8 in response to a request from the receiving device 23 (step S31). Receiving it, the receiving device 23 receives the thumbnail and text information sent from the
接着，若用户操作输入单元25，从而进行显示接收到的缩略图和文本的指示，则文本显示单元31读出在存储单元28中存储着的文本45，显示在显示装置26中，且缩略图显示单元32读出在存储单元28中存储着的缩略图数据46，显示在显示装置26中(步骤S53)。文本数据45和缩略图数据46都被赋予时间信息(从内容的开头部分开始的再现经过时间)，并根据该时间信息，文本和缩略图被同步显示。由此执行图6所示的“阅读模式”。Next, if the user operates the input unit 25 to instruct to display the received thumbnail and text, the text display unit 31 reads out the text 45 stored in the storage unit 28 and displays it on the display device 26, and the thumbnail The display unit 32 reads out the thumbnail image data 46 stored in the storage unit 28, and displays it on the display device 26 (step S53). Both text data 45 and thumbnail image data 46 are given time information (elapsed reproduction time from the beginning of the content), and based on this time information, text and thumbnail images are displayed synchronously. The "read mode" shown in FIG. 6 is thus executed.
接着，若用户操作输入单元25，从而使文本/缩略图画面上下滚动，进行用于选择活动图像的想看的部分的文本的操作，则控制单元24对配送装置1发送包含伴随被选择的文本的时间信息的活动图像配送请求指令(S54)。若接收活动图像配送请求指令(步骤S55)，则视频/声音/文本配送单元5根据接收到的活动图像配送请求指令中包含的时间信息，确定配送开始的位置，生成从该配送开始位置开始的高分辨率的静止图像，并经由通信单元8，先行于视频数据而配送该静止图像(步骤S56)。该静止图像经由通信单元27被接收装置23接收，且被存储在存储单元28(步骤S57)。视频显示单元35读出该静止图像数据而显示在显示装置26。由此，从显示装置26输出高分辨率的静止图像(步骤S58)。Next, when the user operates the input unit 25 to scroll the text/thumbnail screen up and down, and performs an operation for selecting a desired part of the moving image, the control unit 24 transmits to the delivery device 1 a message containing the selected text. The video distribution request command of the time information (S54). If receiving moving image distribution request instruction (step S55), then video/sound/text distribution unit 5 determines the position of distribution start according to the time information contained in the received moving image distribution request instruction, and generates a video from the distribution start position. A high-resolution still image is distributed via the communication unit 8 in advance of the video data (step S56). The still image is received by the receiving device 23 via the communication unit 27, and stored in the storage unit 28 (step S57). The video display unit 35 reads out the still image data and displays it on the display device 26 . As a result, a high-resolution still image is output from the display device 26 (step S58).
与该动作并行，视频/声音/文本配送单元5根据接收到的活动图像配送请求指令中包含的时间信息，确定配送开始的位置，并读出从该配送开始位置开始的视频(活动图像)数据，从而经由通信单元8，接着静止图像数据配送该高分辨率、高帧速度的视频图像(步骤S59)。该视频数据经由通信单元27被接收装置23接收，并被存储在存储单元28(步骤S60)。视频显示单元35读出该视频数据使其显示在显示装置26中。由此，从先行输出的静止图像，成为在显示装置26上显示高分辨率、高帧速度的视频(活动图像)(步骤S61)，从图6所示的阅读模式转移到观看模式，可阅览从在缩略图/文本画面中选择的部分开始的活动图像。In parallel with this action, the video/sound/text distribution unit 5 determines the location where the distribution starts according to the time information contained in the received moving image distribution request command, and reads out the video (moving image) data from the distribution start position. , so that the high-resolution, high-frame-rate video image is distributed next to the still image data via the communication unit 8 (step S59). The video data is received by the receiving device 23 via the communication unit 27, and stored in the storage unit 28 (step S60). The video display unit 35 reads out the video data to display it on the display device 26 . Thus, from the still image output in advance, it becomes a high-resolution, high-frame-rate video (moving image) displayed on the display device 26 (step S61), and the reading mode shown in FIG. 6 is shifted to the viewing mode, allowing browsing The active image starts from the part selected in the thumbnail/text screen.
接着，若用户从输入单元25进行显示切换的操作，则控制单元24对配送装置1发送活动图像配送停止指令(步骤S62)。若接收该活动图像配送停止指令，则视频/声音/文本配送单元6停止活动图像数据的配送动作(步骤S63)。然后，若结束视频的阅览动作，则接收装置23、配送装置1都结束处理(步骤S64、S65)。另一方面，若继续阅览动作，则接收装置23返回步骤S53，将缩略图/文本显示在显示装置26中。由此，从图6所示的观看模式转移到阅读模式。此外，配送装置1返回步骤S55，等待接收活动图像配送请求指令。Next, when the user performs a display switching operation through the input unit 25, the control unit 24 transmits a video distribution stop command to the distribution device 1 (step S62). Upon receiving the movie distribution stop command, the video/audio/text distribution unit 6 stops the distribution operation of the movie data (step S63). Then, when the video browsing operation ends, both the receiving device 23 and the
由此，在由接收装置23接收高分辨率、高帧速度的活动图像而开始显示之前的期间，从配送装置1对接收装置23先行配送高分辨率的静止图像，因此在从进行阅览、检索的显示画面至进行视频、声音的视听的显示画面的切换中，能够提高对于操作的响应性，降低对用户带来的等待时间的压力。Thus, before the receiving device 23 receives a high-resolution, high-frame-rate moving image and starts displaying it, the
另外，在图3中，说明在从配送装置1对接收装置23配送活动图像信息(步骤S20)之前，配送声音信息(步骤S17)的情况，在图4中说明在从配送装置1对接收装置23配送活动图像信息(步骤S43)之前，配送高分辨率、低帧速度的活动图像或低分辨率、高帧速度的活动图像(步骤S39、S40)的情况，在图5中说明了在从配送装置1对接收装置23配送活动图像信息(步骤S59)之前配送静止图像(步骤S56)的情况，但并不限定于此。In addition, in FIG. 3, the situation of distributing sound information (step S17) before distributing video information (step S20) from distributing
例如，在图3～图5的处理中，在从配送装置1对接收装置23配送活动图像信息之前，也可以配送声音信息、高分辨率且低帧速度的活动图像或低分辨率且高帧速度的活动图像、以及静止图像的组合。For example, in the processing of FIGS. 3 to 5 , before distributing moving image information from the
另外，在图4中说明了，在步骤S38中关于活动图像的质量，从配送装置1对接收装置23配送低分辨率且高帧速度的活动图像和高分辨率且低帧速度的活动图像之一(步骤S39、S40)，此后，从配送装置1对接收装置23配送高分辨率且高帧速度的活动图像(步骤S41)的情况，但并不限定于此。In addition, as shown in FIG. 4 , regarding the quality of the moving image in step S38 , the
例如，也可以在图4的步骤S37中，配送装置1确定了应对接收装置23配送的内容之后，从配送装置1对接收装置23配送该内容的静止图像、声音、低分辨率且高帧速度的活动图像、高分辨率且低帧速度的活动图像，此后，从配送装置1对接收装置23配送高分辨率且高帧速度的活动图像(步骤S43)。For example, in step S37 of FIG. 4 , after the
从配送装置1对接收装置23配送的静止图像、声音、低分辨率且高帧速度的活动图像、高分辨率且低帧速度的活动图像的配送顺序可以是以任意的顺序进行，但优选按照静止图像、声音、低分辨率且高帧速度的活动图像、高分辨率且低帧速度的活动图像的顺序配送。此外，也可以按照声音、静止图像、低分辨率且高帧速度的活动图像、高分辨率且低帧速度的活动图像的顺序配送。The distribution order of still images, audio, low-resolution and high-frame-rate moving images, and high-resolution and low-frame-rate moving images distributed from the
如上所述，在从配送装置1对接收装置23配送数据量多的高分辨率且高帧速度的活动图像之前，从配送装置1对接收装置23先行配送数据量少的低分辨率且高帧速度的活动图像或高分辨率且低帧速度的活动图像，从而能够减轻接收装置23的用户的压力。As described above, before distributing high-resolution and high-frame-rate moving images with a large amount of data from the
这样，在由接收信息量多的高分辨率、高帧速度的活动图像而开始显示之前的期间，先行显示信息量少的静止图像或着信息量少的活动图像，因此在从进行阅览、检索的显示画面至进行视频、声音的视听的显示画面的切换中，能够提高对于操作的响应性，降低对用户带来的等待时间的压力。In this way, a still image with a small amount of information or a moving image with a small amount of information is displayed in advance before the display of a high-resolution and high-frame-rate moving image with a large amount of information is received. When switching from the display screen of the display screen to the display screen for viewing and listening to video and audio, the responsiveness to operations can be improved, and the pressure on the waiting time for the user can be reduced.
如上说明那样，当从基于文本/缩略图显示单元29的显示切换到基于视频/声音/显示单元33的显示的情况下，通常在对应的视频、声音对数据缓冲器的缓冲结束之后，进行切换，因此虽然转移显示需要时间，但由于使在接收装置23内存储的缩略图和经由通信单元27提供的时刻信息同步，先行进行基于信息量少的数据的视频显示和声音输出，因此能够提高显示转移时的响应性，能够降低对用户带来的等待时间的压力。As explained above, when switching from the display based on the text/thumbnail display unit 29 to the display based on the video/sound/display unit 33, usually after the buffering of the corresponding video and sound to the data buffer is completed, the switch is performed. Therefore, although it takes time to transition and display, since the thumbnail images stored in the receiving device 23 are synchronized with the time information provided via the communication unit 27, video display and sound output based on data with a small amount of information are performed in advance, so the display can be improved. Responsiveness during transfer can reduce the pressure on users' waiting time.
