具体实施方式Detailed ways

一般而言，在数字生活网络联盟(Digital Living Network Alliance，DLNA)环境下各装置并无法分享文字文件，因此，对于习惯在观赏影片档观看字幕或在聆听音乐文件观看歌词的使用者而言是相当不便的。据此，本发明提出一种播放多媒体文件的方法及文件共享系统，可在DLNA环境下分享多媒体文件及其对应的文字文件。为了使本发明的内容更为明了，以下特举实施例作为本发明确实能够据以实施的范例。Generally speaking, in the Digital Living Network Alliance (Digital Living Network Alliance, DLNA) environment, devices cannot share text files. Therefore, for users who are used to watching subtitles while watching video files or watching lyrics while listening to music files quite inconvenient. Accordingly, the present invention proposes a method for playing multimedia files and a file sharing system, which can share multimedia files and their corresponding text files in a DLNA environment. In order to make the content of the present invention clearer, the following specific examples are given as examples in which the present invention can actually be implemented.

图1是依照本发明一实施例所示出的文件共享系统的方块图。请参照图1，文件共享系统100包括服务端装置110与播放端装置120。在本实施例中，文件共享系统100符合数字生活网络联盟(Digital Living NetworkAlliance，DLNA)协定。在DLNA环境下，服务端装置110例如为数字媒体服务器(Digital Media Server，DMS)，播放端装置120例如为数字媒体播放器(Digital Media Player，DMP)、数字媒体控制器(Digital MediaController，DMC)或是具有屏幕的数字媒体渲染器(Digital Media Renderer，DMR)。FIG. 1 is a block diagram of a file sharing system according to an embodiment of the present invention. Please refer to FIG. 1 , the file sharing system 100 includes a server device 110 and a player device 120 . In this embodiment, the file sharing system 100 complies with the Digital Living Network Alliance (Digital Living Network Alliance, DLNA) protocol. In the DLNA environment, the server device 110 is, for example, a digital media server (Digital Media Server, DMS), and the player device 120 is, for example, a digital media player (Digital Media Player, DMP), a digital media controller (Digital Media Controller, DMC) Or a Digital Media Renderer (DMR) with a screen.

服务端装置110具有多媒体资料库，以在多媒体资料库中储存多媒体文件。而播放端装置120可以播放服务端装置110中的多媒体文件。进一步地说，播放端装置120用以连接至服务端装置110来选择其中一个多媒体文件，并且依据所选择的多媒体文件的名称，在文件共享系统100中搜索对应的文字文件(例如，字幕档或是歌词文件)，并且下载文字文件，以同时播放多媒体文件与文字文件。The server device 110 has a multimedia database for storing multimedia files in the multimedia database. And the player device 120 can play the multimedia files in the server device 110 . Furthermore, the player device 120 is used to connect to the server device 110 to select one of the multimedia files, and according to the name of the selected multimedia file, search for a corresponding text file (for example, a subtitle file or a subtitle file) in the file sharing system 100 is the lyrics file), and download the text file to play the multimedia file and the text file at the same time.

以下即搭配上述文件共享系统100来详细说明播放多媒体文件的方法各步骤。The steps of the method for playing multimedia files will be described in detail below in conjunction with the above-mentioned file sharing system 100 .

图2是依据本发明一实施例所示出的播放多媒体文件的方法流程图。请同时参照图1及图2，在步骤S205中，播放端装置120连接至服务端装置110以选择多媒体文件。当播放端装置120接收到播放命令时，其会依据所选择的多媒体文件而取得一多媒体网址。在此，多媒体网址记录了多媒体文件的所在位置，并且记录多媒体文件的名称。多媒体网址例如为“http://10.36.141.70:8200/MediaItems/Video.avi”，其中，“Video.avi”为多媒体文件的文件名称，而“http://10.36.141.70:8200/MediaItems/”为此多媒体文件的所在位置。Fig. 2 is a flowchart of a method for playing a multimedia file according to an embodiment of the present invention. Please refer to FIG. 1 and FIG. 2 at the same time. In step S205, the player device 120 connects to the server device 110 to select a multimedia file. When the player device 120 receives the play command, it will obtain a multimedia URL according to the selected multimedia file. Here, the multimedia URL records the location of the multimedia file and the name of the multimedia file. The multimedia URL is, for example, "http://10.36.141.70:8200/MediaItems/Video.avi", where "Video.avi" is the file name of the multimedia file, and "http://10.36.141.70:8200/MediaItems/ " for the location of this multimedia file.

接着，在步骤S210中，播放端装置120会依据多媒体文件的名称在文件共享系统100中搜索对应的文字文件。例如，可先在播放端装置120搜索是否有符合的文字文件。如果在播放端装置120中未搜索到文字文件，再至提供多媒体文件的服务端装置110中搜索是否具有对应的文字文件。若无，则在文件共享系统100的另一服务端装置(未示出)中来搜索文字文件。Next, in step S210 , the player device 120 searches the file sharing system 100 for a corresponding text file according to the name of the multimedia file. For example, the player device 120 may first search whether there is a matching text file. If no text file is found in the player device 120 , then search whether there is a corresponding text file in the server device 110 that provides multimedia files. If not, search for text files in another server device (not shown) of the file sharing system 100 .

一般来说，以影片文件而言，其字幕文件的名称通常会与影片文件相符，或者，字幕文件的内容一开始也通常会具有与其影片文件的名称相符的字串。因此，在搜索对应的文字文件时，播放端装置120可以去比对多媒体文件的名称与搜索到的文字文件的名称是否相同，或是分析文字文件的内容是否具有符合多媒体文件的名称的字串。Generally speaking, for a movie file, the name of the subtitle file usually matches the movie file, or the content of the subtitle file usually has a character string matching the name of the movie file at the beginning. Therefore, when searching for the corresponding text file, the player device 120 can compare whether the name of the multimedia file is the same as the name of the searched text file, or analyze whether the content of the text file has a string matching the name of the multimedia file. .

在找到文字文件之后，在步骤S215中，播放端装置120将文字文件下载至其中。由于文字文件并不会占去太多储存空间，因此，便直接将搜索到的文字文件下载至播放端装置120来储存。然后，在步骤S220中，播放端装置120便能够同时播放多媒体文件与文字文件。在此，播放端装置120可利用串流(streaming)技术来播放服务端装110中的多媒体文件。After finding the text file, in step S215, the player device 120 downloads the text file to it. Since the text files do not take up too much storage space, the searched text files are directly downloaded to the player device 120 for storage. Then, in step S220, the player device 120 can play the multimedia file and the text file at the same time. Here, the player device 120 can use streaming technology to play the multimedia files in the server device 110 .

而为了要让服务端装置110得以分享文字文件，并且让播放端装置120能够搜索到文字文件，在此可修改服务端装置110及播放端装置120的架构，使得字幕文件或歌词等文字文件可以由服务端装置110分享出来，并且可以在播放端装置120中显示。In order to allow the server device 110 to share text files and allow the player device 120 to search for text files, the architecture of the server device 110 and the player device 120 can be modified so that text files such as subtitle files or lyrics can be It is shared by the server device 110 and can be displayed on the player device 120 .

图3是依照本发明一实施例所示出的网络通讯协定堆迭的示意图。本实施例是以通用随插即用(Universal Plug and Play，UPnP)架构来说明。请参照图3，在本实施例中，网络通讯协定堆迭(network protocol stack)包括5层，以下为由下往上逐层说明。第一层为网络连结层，例如为Wi-Fi或是以太网络(Ethernet)等实体的无线通讯系统。第二层为网络堆迭层，例如为传输控制协定(Transmission Control Protocol，TCP)和网际网络协定(Internet Protocol，IP)，其用以负责设备的IP位址，TCP/IP提供用来实现UPnP设备间网络连接的基本协定集。第三层是传输协定层，例如为超文件传输协定(Hypertext Transmission Protocol，HTTP)。第四层为UPnP设备控制协议(Device Control Protocol，DCP)层，用以让文件共享系统100中的各装置能够区分彼此并互相通联，任何UPnP设备都必须使用这一层。另外，在HTTP层之上还包括了媒体串流模组，使得多媒体文件得以串流分享。第五层为媒体管理层，在此指定UPnP AV(Audio and Video)协议，以提供规则让各种媒体能够有效被识别、管理与散布。UPnP AV协议提供了媒体服务器(Media Server)，以负责定位可用的媒体资源，向网络中其他装置提供各种娱乐内容。FIG. 3 is a schematic diagram of a stack of network communication protocols according to an embodiment of the present invention. This embodiment is described with a Universal Plug and Play (UPnP) architecture. Please refer to FIG. 3 , in this embodiment, the network protocol stack (network protocol stack) includes 5 layers, and the following is a layer-by-layer description from bottom to top. The first layer is a network connection layer, such as a physical wireless communication system such as Wi-Fi or Ethernet. The second layer is the network stack layer, such as Transmission Control Protocol (Transmission Control Protocol, TCP) and Internet Protocol (Internet Protocol, IP), which are used to be responsible for the IP address of the device, and TCP/IP is provided to implement UPnP Basic set of protocols for network connections between devices. The third layer is a transport protocol layer, such as Hypertext Transmission Protocol (HTTP). The fourth layer is the UPnP device control protocol (Device Control Protocol, DCP) layer, which is used to enable each device in the file sharing system 100 to distinguish and communicate with each other. Any UPnP device must use this layer. In addition, a media streaming module is included on top of the HTTP layer, enabling multimedia files to be streamed and shared. The fifth layer is the media management layer, where the UPnP AV (Audio and Video) protocol is specified to provide rules so that various media can be effectively identified, managed and distributed. The UPnP AV protocol provides a media server (Media Server), which is responsible for locating available media resources and providing various entertainment content to other devices in the network.

媒体服务器提供了内容目录服务(Content Directory Service)以及连接管理服务(Connection Manager Service)。内容目录服务提供了资料结构及存取的命令，让播放端装置120能够去播放服务端装置110分享出的内容。The media server provides Content Directory Service and Connection Manager Service. The content directory service provides data structure and access commands, so that the player device 120 can play the content shared by the server device 110 .

举例来说，服务端装置110采用UPnP AV协议，而提供了一个内容目录服务配置在媒体服务器中，以使播放端装置120发现媒体服务器。内容目录服务用以定义媒体资料库的资料结构以及存取命令。在此，资料结构包括多个多媒体类别节点以及文字类别节点，并且文字类别节点中定义了多个属性分类。以下举一实施例来说明。For example, the server device 110 adopts the UPnP AV protocol, and provides a content directory service configured in the media server, so that the player device 120 can discover the media server. The content directory service is used to define the data structure and access commands of the media database. Here, the data structure includes multiple multimedia category nodes and text category nodes, and multiple attribute categories are defined in the text category nodes. An example is given below for illustration.

图4是依照本发明一实施例所示出的内容目录服务的资料结构的示意图。在本实施例中，在内容目录服务的资料结构中新增了文字节点，使得服务端装置110能够分享文字文件。请参照图4，在内容目录服务的根节点之下包括多个类别节点，每一类别节点具有多个属性节点，这些类别节点包括影音节点(音乐、视讯及图片)与文字节点(字幕及歌词)。FIG. 4 is a schematic diagram of a data structure of a content directory service according to an embodiment of the present invention. In this embodiment, a text node is added in the data structure of the content directory service, so that the server device 110 can share text files. Please refer to Figure 4, under the root node of the content directory service, there are multiple category nodes, each category node has multiple attribute nodes, and these category nodes include video and audio nodes (music, video and pictures) and text nodes (subtitles and lyrics) ).

据此，播放端装置120在搜索文字文件时，便可自文字节点中来进行搜索。以播放影片文件为例，当播放端装置120接收到播放命令而得到多媒体文件的多媒体网址及多媒体文件的名称时，依据内容目录服务所定义的资料结构，而去搜索服务端装置110中的“字幕”的树状目录里是否有相对应的字幕文件。若有，则下载字幕文件并在播放多媒体文件时播放字幕文件。若无，则去其它服务端装置中寻找是否有符合的字幕文件。另外，也可根据多媒体文件的属性，而在文字节点下的对应的属性分类中，寻找符合多媒体文件的名称的文字文件。例如，根据影片文件的类型(如，喜剧类)而在文字节点下的对应的“类型”属性分类中进行寻找，以提高搜索效率。Accordingly, when the player device 120 searches for a text file, it can search from text nodes. Taking playing a movie file as an example, when the player device 120 receives the play command and obtains the multimedia URL of the multimedia file and the name of the multimedia file, it will search for "" in the server device 110 according to the data structure defined by the content directory service. Whether there is a corresponding subtitle file in the tree directory of "Subtitle". If so, download the subtitle file and play the subtitle file when playing the multimedia file. If not, then go to other server devices to find whether there is a matching subtitle file. In addition, according to the attribute of the multimedia file, the text file matching the name of the multimedia file can be searched in the corresponding attribute classification under the text node. For example, according to the type of movie file (eg, comedy), search in the corresponding "type" attribute classification under the text node, so as to improve the search efficiency.

在此，文字文件可以与多媒体文件储存在同一服务端装置中，或者文字文件可以储存在与多媒体文件不同的服务端装置中。举例来说，图5A及图5B是依照本发明一实施例所示出的文件共享系统的示意图。请参照图5A及图5B，在图5A中，文件共享系统500包括服务端装置510及播放端装置520。其中，播放端装置520例如为屏幕，服务端装置510例如为电脑主机。在服务端装置510中存在有多媒体文件511及文字文件513。Here, the text file and the multimedia file can be stored in the same server device, or the text file can be stored in a server device different from the multimedia file. For example, FIG. 5A and FIG. 5B are schematic diagrams of a file sharing system according to an embodiment of the present invention. Please refer to FIG. 5A and FIG. 5B . In FIG. 5A , thefile sharing system 500 includes aserver device 510 and aplayer device 520 . Wherein, theplayer device 520 is, for example, a screen, and theserver device 510 is, for example, a computer host. Amultimedia file 511 and atext file 513 exist in theserver device 510 .

另外，文件共享系统500还可包括两台或两台以上的服务端装置，如图5B所示，文件共享系统500还包括服务端装置530。在此，假设服务端装置510存有多媒体文件511，而在服务端装置530中存在有符合多媒体文件511的文字文件531。当播放端装置520欲播放服务端装置510的多媒体文件511时，其会在服务端装置530中搜索到文字文件531，之后将文字文件531下载至播放端装置520中，以在串流播放多媒体文件511的同时播放文字文件531。如此一来，便能够在DLNA环境之下来分享多媒体文件及文字文件。In addition, thefile sharing system 500 may also include two or more server devices. As shown in FIG. 5B , thefile sharing system 500 further includes aserver device 530 . Here, assume that theserver device 510 stores amultimedia file 511 , and theserver device 530 has atext file 531 corresponding to themultimedia file 511 . When theplayer device 520 wants to play themultimedia file 511 of theserver device 510, it will search for thetext file 531 in theserver device 530, and then download thetext file 531 to theplayer device 520 to play the multimedia in the stream Thetext file 531 is played simultaneously with thefile 511. In this way, multimedia files and text files can be shared under the DLNA environment.

综上所述，本发明可在数字家庭的环境下分享多媒体文件及其对应的文字文件，并且可在播放端装置串流播放多媒体文件的同时也播放文字文件。如此一来，使用者可享受更棒的数字家庭生活，而不用局限于原本数字家庭的限制。To sum up, the present invention can share multimedia files and their corresponding text files in a digital home environment, and can also play text files while streaming the multimedia files on the player device.
