Description

选择可播放码率内容的方法和装置 技术领域  Method and apparatus for selecting playable content content
本发明涉及通信网络技术领域， 尤其涉及一种选择可播放码率内容的 方法和装置。  The present invention relates to the field of communication network technologies, and in particular, to a method and apparatus for selecting playable content.
背景技术 Background technique
基于超文本传输协议的自适应流媒体 ( Hyper text Transfer Protoco l ( HTTP ) Adapt ive Streaming , HAS )技术采用 HTTP 的方式向用户传送媒 体内容， 该技术因为可以降低头端服务器的技术复杂度， 而且提升了媒体 内容在网络设备中的穿透能力， 目前已成为流媒体视频行业发展的趋势。  Hypertext Transfer Protocol (HTTP) Adaptive Streaming (HAS) technology uses HTTP to deliver media content to users. This technology can reduce the technical complexity of the headend server. It has improved the penetration of media content in network devices and has become a trend in the development of streaming video industry.
HAS技术的一个关键是将内容（即同一个频道或者电影）顺序的切割成 分片， 每个分片的码率、 分辨率、 编码相同， 每个分片的时间长度相同， 一般为 2到 10秒左右， 这样的一组分片的描述信息和访问链接构成一个播 放列表。 服务器针对同一份内容可以提供不同码率的多个视频文件， 因此 存在多个播放列表， 每个播放列表提供不同码率的分片。 这些播放列表及 分片部署在服务器上， 终端使用 HTTP协议从服务器顺序请求某个播放列表 的分片进行播放。 因为不同播放列表的码率不同， 终端可以根据变化的网 络情况动态选择不同码率的分片， 从而实现码率的自适应。 为了终端选择 合适的播放列表， 服务器还提供一个索引文件， 记录了所有可选播放列表 的码率信息、 访问链接以及编码格式， 且索引文件中对于每种码率播放列 表的描述按照码率从小到大排列。  One key to HAS technology is to cut the content of the content (that is, the same channel or movie) in sequence. Each patch has the same bit rate, resolution, and code. Each slice has the same length of time, usually 2 to 10. About seconds, the description information and access links of such a group of tablets constitute a playlist. The server can provide multiple video files of different code rates for the same content, so there are multiple playlists, each of which provides segments of different code rates. These playlists and shards are deployed on the server, and the terminal sequentially requests the shards of a playlist from the server to play using the HTTP protocol. Because the code rates of different playlists are different, the terminal can dynamically select the slices of different code rates according to the changed network conditions, thereby realizing the adaptation of the code rate. In order to select a suitable playlist for the terminal, the server also provides an index file, which records the code rate information, the access link and the encoding format of all the optional playlists, and the description of the playlist for each code rate in the index file is small according to the code rate. Arrange to the big.
现有技术中， 终端请求播放内容时， 首先获取到索引文件， 根据索引 文件中的播放列表的信息以及终端可用带宽信息， 先请求索引文件中最低 码率的播放列表， 成功播放一个分片后， 尝试请求可用带宽范围内更高码 率的播放列表， 直至稳定至某一个合适的码率。 终端在可用带宽范围内逐 步尝试更高码率内容的过程中， 往往可能出现请求播放内容的码率超出终 端最大支持码率的情况， 导致播放会卡顿、 黑屏或花屏一段时间， 然后自 动降低码率请求低码率的分片再播放， 从而用户播放体验不好。  In the prior art, when the terminal requests to play the content, the first obtains the index file, and according to the information of the playlist in the index file and the available bandwidth information of the terminal, first requests the playlist of the lowest bit rate in the index file, and successfully plays a slice. , Try to request a higher bit rate playlist within the available bandwidth range until it stabilizes to a suitable bit rate. In the process of gradually trying to try higher bit rate content in the available bandwidth range, the terminal may often exceed the maximum supported bit rate of the terminal, causing the playback to be stuck, black screen or flower screen for a period of time, and then automatically reduced. The code rate requests the low bit rate of the slice to be played again, so that the user's playback experience is not good.
因此， 现有技术中终端在播放内容时， 存在可能请求了超出终端最大 支持码率的内容而播放异常的问题， 因此降低了用户播放体验。 发明内容 Therefore, in the prior art, when the terminal plays the content, there is a problem that the content exceeding the maximum supported bit rate of the terminal is requested to be played abnormally, thereby reducing the user playing experience.
