Description

一种附加节目播放系统、 方法和装置 技术领域  Additional program playing system, method and device
本发明涉及流媒体技术领域, 更具体地说, 涉及一种附加节目播放 系统、 方法和装置。 发明背景  The present invention relates to the field of streaming media technology, and more particularly to an additional program playing system, method and apparatus. Background of the invention
流媒体技术是近年来兴起的一种在线播放技术, 也就是边下载边播 放, 播放器在下载多媒体文件的同时进行播放。 播放器在客户端的内存 中设置有緩沖区, 通常为几兆字节, 播放器在緩沖区达到设定的数据量 后开始解码播放。 这个过程通常需要几秒钟时间, 与下载完播放相比大 大节省了等待时间。 由于客户端在播放过程中不保存多媒体文件, 该技 术还节省了客户端的存储空间。  Streaming media technology is an online playback technology that has emerged in recent years, that is, playback while playing, and the player plays while downloading multimedia files. The player has a buffer set in the client's memory, usually a few megabytes, and the player starts decoding and playing after the buffer reaches the set amount of data. This process usually takes a few seconds, saving a lot of waiting time compared to downloading the playback. Since the client does not save multimedia files during playback, this technology also saves storage space on the client side.
由于流媒体技术在较低带宽(例如 14.4Kbps )下即可使客户端欣赏 到连续不断的较高品质的音频节目和视频节目, 因此被广泛应用于互联 网多媒体新闻发布、 在线直播、 网络广告、 网络视频广告、 电子商务、 视频点播、 远程教育、 网络电台、 实时视频会议等互联网的信息服务领 域。典型的流媒体技术应用主要有视频、音频的直播、 网络电视(IP-TV ) 等, 如网上直播奥运会, 春节晚会, 名人访谈等等。  Because streaming media technology enables users to enjoy continuous high-quality audio programs and video programs at lower bandwidth (for example, 14.4Kbps), it is widely used in Internet multimedia news release, online live broadcast, online advertising, Internet video advertising, e-commerce, video on demand, distance education, internet radio, real-time video conferencing, etc. Internet information services. Typical streaming media applications include video, audio live, and Internet-based television (IP-TV), such as live webcasts, Chinese New Year parties, celebrity interviews, and more.
现有的流媒体应用中, 在发布源端, 附加节目 (例如广告)通常与 主节目 (例如网络电视)一起编码后通过互联网传到客户端, 客户端解 码后附加节目与主节目一起播放。  In existing streaming media applications, at the source of the distribution, additional programs (e.g., advertisements) are typically encoded with the main program (e.g., Internet TV) and transmitted to the client over the Internet. The client decodes the attached program and plays it along with the main program.
此外, 在流媒体应用中播放附加节目的另一种方式为: 在发布源暂 停主节目数据流, 并开始播放附加节目数据流, 在附加节目数据流播放 完之后, 再继续主节目的播放。 然而, 上述附加节目播放的方式不够灵活, 主节目与附加节目捆绑 在一起, 不能随意更换。 并且由于编解码工作在发布源完成, 效率较低, 影响主节目的观看。 发明内容 In addition, another way to play the additional program in the streaming application is to pause the main program data stream at the publishing source and start playing the additional program data stream, and then continue the main program after the additional program data stream is played. However, the manner in which the above-mentioned additional programs are played is not flexible enough, and the main program is bundled with the additional programs and cannot be replaced at will. And because the codec work is completed in the release source, the efficiency is low, which affects the viewing of the main program. Summary of the invention
本发明要解决的技术问题在于, 针对上述的附加节目播放方式不够 灵活、影响主节目播放问题,提供一种附加节目播放系统、 方法和装置。  The technical problem to be solved by the present invention is to provide an additional program playing system, method and device for the above-mentioned additional program playing mode which is not flexible enough to affect the main program playing problem.
本发明实施例提供一种附加节目播放系统, 包括发布主节目数据的 服务器和播放所述主节目数据的客户端, 所述服务器包括:  An embodiment of the present invention provides an additional program playing system, including a server that issues main program data and a client that plays the main program data, where the server includes:

The control unit 123 is for parsing the play instruction from the additional program management unit 111, and acquires additional program data corresponding to the additional program identification from the additional program storage unit 112.
显示单元 124用于生成显示区域, 并在显示区域播放控制单元 123 获取的附加节目数据。 显示单元 124在主节目播放单元 122播放主节目 数据的同时播放附加节目数据。  The display unit 124 is for generating a display area, and plays additional program data acquired by the control unit 123 in the display area. The display unit 124 plays the additional program data while the main program playing unit 122 plays the main program data.
在本实施例中, 当附加节目数据为视频广告或静态图像广告时, 显 示单元 124生成的显示区域在主节目播放单元 122的显示区域之外; 当 附加节目数据为文字广告或通知消息时, 显示单元 124生成的显示区域 在主节目播放单元 122的显示区域之外或叠加在主节目播放单元 122的 显示区域之上。  In this embodiment, when the additional program data is a video advertisement or a still image advertisement, the display area generated by the display unit 124 is outside the display area of the main program playing unit 122; when the additional program data is a text advertisement or a notification message, The display area generated by the display unit 124 is outside the display area of the main program playing unit 122 or superimposed on the display area of the main program playing unit 122.
如图 3所示, 是本发明一种附加节目播放方法实施例的示意图, 本 发明的方法用于在客户端 12播放服务器 11中主节目数据之外的附加节 目数据, 其中, 附加节目数据可以是视频广告、 静态图像广告、 文字广 告或通知消息等, 而主节目数据可以是网络电视节目、 视频访谈等。  As shown in FIG. 3, it is a schematic diagram of an embodiment of an additional program playing method according to the present invention. The method of the present invention is used to play additional program data other than main program data in the server 11 at the client terminal 12, wherein the additional program data may be It is a video advertisement, a still image advertisement, a text advertisement or a notification message, and the main program data may be a network television program, a video interview, or the like.
本发明的方法具体包括以下步骤:  The method of the present invention specifically includes the following steps:
步骤 S31: 服务器 11发布附加节目播放指令。 在本实施例中, 附加 节目数据存储于服务器 11中, 且每一附加节目具有一个附加节目标识。 服务器 11 发布的播放指令包括附加节目标识以及其它一些播放参数, 例如播放时显示区域的位置、 尺寸等。  Step S31: The server 11 issues an additional program play instruction. In the present embodiment, the additional program data is stored in the server 11, and each additional program has an additional program identification. The playback instructions issued by the server 11 include additional program identifications and other playback parameters, such as the location, size, etc. of the display area during playback.
步骤 S32: 客户端 12经由网络获取来自服务器 11的播放指令, 并 根据该播放指令从服务器 11 获取附加节目数据。 在本实施例中, 客户 端 12接收到来自服务器 11的播放指令后, 解析该播放指令, 以获取附 加节目标识以及其它播放参数; 然后从服务器 11 获取与上述附加节目 标识对应的附加节目数据。  Step S32: The client 12 acquires a play instruction from the server 11 via the network, and acquires additional program data from the server 11 according to the play instruction. In this embodiment, after receiving the play command from the server 11, the client 12 parses the play command to acquire the additional program identifier and other play parameters; and then acquires additional program data corresponding to the above-mentioned additional program identifier from the server 11.
步骤 S33:客户端 12根据播放参数播放步骤 S32中获取的附加节目 数据。 在本实施例中, 客户端 12首先生成显示区域, 以在该显示区域 播放该附加节目数据。 当附加节目数据为视频或静态图像数据时, 客户 端 12在主节目数据的显示区域之外播放附加节目数据; 当附加节目数 据为文字数据时, 客户端 12在主节目数据的显示区域之外或者主节目 显示区域之上播放附加节目数据。 Step S33: The client 12 plays the additional program acquired in step S32 according to the playing parameters. Data. In the present embodiment, the client 12 first generates a display area to play the additional program data in the display area. When the additional program data is video or still image data, the client 12 plays additional program data outside the display area of the main program data; when the additional program data is text data, the client 12 is outside the display area of the main program data. Or play additional program data on top of the main program display area.
在本实施例中, 客户端 12在播放主节目数据的同时播放附加节目 数据。  In the present embodiment, the client 12 plays additional program data while playing the main program data.
上述系统及方法中, 由于附加节目数据不参与主节目数据的编解 码, 从而不会影响主节目数据播放的质量。  In the above system and method, since the additional program data does not participate in the encoding of the main program data, the quality of the main program data playback is not affected.
以上所述, 仅为本发明较佳的具体实施方式, 但本发明的保护范围 并不局限于此, 任何熟悉本技术领域的技术人员在本发明揭露的技术范 围内, 可轻易想到的变化或替换, 都应涵盖在本发明的保护范围之内。 因此, 本发明的保护范围应该以权利要求的保护范围为准。  The above is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of changes or within the technical scope disclosed by the present invention. Alternatives are intended to be covered by the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
