Definitions
- the present invention relates to streaming media technologies, and in particular, to a method, device and system for acquiring streaming media data.
- streaming media technology In recent years, Internet video services have developed rapidly, and video content traffic has accounted for half of the entire Internet traffic. When it comes to Internet video services, I have to mention streaming media technology. It is precisely because of the continuous development of streaming media technology that the rapid development of Internet video services has been promoted.
- RTSP/RTP Real Time Streaming Protocol
- connection-oriented streaming media technology The class is a streaming media technology that uses the connectionless HTTP (Hyper Text Transfer Protocol) progressive download of the current mainstream video website.
- RTSP/RTP streaming media technology is an end-to-end download technology based on multicast application layer protocol, in which RTP is used for streaming media data transmission, RTSP is used for statistics, management and control of RTP transmission, and the two work together to be significant. Improve the transmission efficiency of real-time data on the network.
- RTSP/RTP streaming technology has the following drawbacks:
- the logic implementation of the RTSP/RTP protocol stack is more complex, compared to HTTP technology, support
- RTSP/RTP terminal software and hardware implementation is difficult, especially for embedded terminals; in addition, the network port number (554) used by the RTSP protocol may be blocked by firewalls and NATs in some user networks. This makes it unusable. Although some streaming servers can tunnel the RTSP on HTTP port 80, it is not particularly convenient to deploy.
- HTTP streaming software for progressive downloads means: HTTP endpoints can be used throughout the streaming file.
- the streaming media data can be played before being downloaded. If both the HTTP terminal and the streaming server support HTTP 1.1, the HTTP terminal can also select a time point from the part that has not been downloaded to start the media playback.
- mainstream video sites use HTTP progressive download to distribute streaming media.
- HTTP progressive download streaming technology uses stateless
- the HTTP protocol when the HTTP terminal requests streaming media data from the streaming media server, the streaming media server delivers the requested streaming media data to the terminal.
- the streaming media server does not record the status of the terminal, and each request of the HTTP terminal is once. Sexually independent conversation.
- the significant advantage of the HTTP progressive download solution is that it only needs to maintain a standard web server, and the workload and complexity of its installation and maintenance is better than that of a dedicated streaming server. It’s much easier to order.
- the bandwidth is easy to waste.
- HTTP-based progressive downloads are only available for on-demand content, not for live content.
- HTTP Adaptive Streaming hereinafter referred to as ''HAS'
- HAS technology can greatly enhance the user's media playback experience.
- the technical complexity of the streaming media server is reduced.
- the HTTP-based transmission method improves the penetration capability of streaming media data in network devices.
- HAS technology has become a trend in the streaming video industry.
- each block has the same length of time, usually about 10 seconds.
- Each block can be coded according to different code rates to obtain multiple block rate blocks. That is, the streaming media server locally stores streaming media files encoded at different bit rates, and the same content is streamed.
- the volume file is respectively encoded to obtain a streaming media file of a code rate of 128 kbps, a streaming media file of a code rate of 256 kbps, a streaming media file of a code rate of 512 kbps, and the like.
- the streaming media server also provides an index file in which information about streaming media files of different code rates is recorded. After downloading the index file from the streaming media server, the terminal requests to download and play the streaming media file with the lowest bit rate according to the information recorded therein.
- the current The terminal capability and network state can support the lowest bit rate, and the terminal attempts to request a streaming file with a higher bit rate. If a block of the higher rate rate streaming file can be successfully downloaded and played, continue to try to download again. A streaming media file with a higher bit rate. If a block of a higher-rate streaming media file cannot be successfully downloaded and played, the streaming file with the lowest bit rate will continue to be downloaded and played, and so on, until it is stable. Download and play streaming files at a suitable bit rate.
- the complete streaming media file is divided into multiple HTTP-based partitions.
- the terminal When starting a streaming media session, the terminal first flows from the stream.
- the media server downloads an extended M3U playlist file containing metadata (ie, an index file, followed by a playlist file).
- metadata ie, an index file, followed by a playlist file.
- the description of the playlist file is as follows:
- a playlist file is a text file composed of a plurality of independent lines, each line is distinguished by a carriage return or a line feed flag, and each line records a URI of a block at a certain code rate and corresponding attribute information, the attribute information.
- BANDWIDTH Bandwidth, mandatory parameter, indicating the bandwidth required for the block transfer at this bit rate
- PROGRAM-ID This value is a decimal integer that uniquely identifies a specific description within the scope of the Playlist file
- CODECS decoder information, optional parameters
- RESOLUTION which indicates the resolution of the AUDIO required for the block at this bit rate during playback of the terminal: Audio information, which must be in the "EXT-X-MEDIA" tab of the AUDIO category.
- the "GROUP-ID” attribute value matches, indicating the audio information required for the block at the code rate to be played by the terminal;
- VIDEO The video information must match the value of the "GROUP-ID" attribute in the "EXT-X-MEDIA" tab of the VIDEO category, indicating the video information required for the block at that bit rate to be played in the terminal.
- the terminal After downloading the playlist file from the streaming media server, the terminal downloads and plays the streaming media file according to the URI (Uniform Resource Identifier) of each different code rate recorded in the playlist file according to the code rate from low to high.
- the block is stabilized at a suitable code rate, and then the streaming media file of the appropriate code rate is continuously downloaded and played.
- each fragmentation duration is about 10 seconds.
- the tens of seconds of streaming media files that are just beginning to be downloaded are low-coded. Rate of streaming media data, because the higher the bit rate, the richer the picture details of the streaming media data, that is, the better the image quality. Therefore, the quality of the first few tens of seconds of streaming media data downloaded and played by the above streaming media acquisition scheme is poor.

- the terminal accesses various types of networks, it is suitable for the code rate of the downloaded streaming media file, so that the terminal can directly request the suitable code when performing the streaming media service (such as when the terminal requests to obtain the HLS-based streaming media data).
- Rate streaming media files without attempting to download from the lowest bit rate, avoiding the problem of poor quality of streaming media data acquired in the first few tens of seconds in the existing streaming media acquisition scheme, so that all streaming media data downloaded and played is The quality is good.
- the embodiment of the present invention includes a process of determining a code rate by the network side, a process of transmitting the determined code rate by the network side as a recommended value to the terminal, and requesting the streaming media file by the terminal according to an appropriate code rate. The process is explained below.
- Embodiment 1 is a diagrammatic representation of Embodiment 1:
- FIG. 1 it is a schematic diagram of a method for obtaining streaming media data in the first embodiment, where the method mainly includes the following steps:
- Step 101 Receive recording information reported by each terminal when performing a streaming media service within a set duration.
- the record information includes a device type of the terminal, a network type of the network accessed by the terminal, and a code rate of the downloaded streaming media file by the terminal.
- the terminal belonging to the same EPG can periodically upload the locally generated record information to the EPG, and the terminal can also perform the streaming service every time. If the record information is reported, the executor of this step can be an EPG, or other network elements in the network side.
- the terminal can automatically generate a record information when the streaming media service is executed each time (for example, the terminal downloads and plays the service of the HLS-based streaming media data), and records the terminal when the streaming media service is executed.
- the terminal can also add its own device type to the recorded information.
- the network type may be a WLAN (Wireless LAN) type network or a cellular network (Cellular); the device type of the terminal may be Android (Android) type or Symbian type; terminal downloaded
- the code rate of the streaming media file can be 128Kbps, 256Kbps or 512Kbps.
- the five records received by the three terminals are as follows:
- the code rate of the downloaded streaming media file is 256 Kbps
- the code rate of the downloaded streaming media file is 512 Kbps
- the download rate of the streaming media file is 256Kbps.
- the download duration of the downloaded streaming media file may also be included. Since the conventional streaming media service sequentially attempts to download and play the streaming media data according to the code rate from low to high, For the case where the download duration is less than the threshold (for example, the download duration is less than 20 seconds), it can be seen that the download process of the streaming media file is an attempt to download, and if the download is not stable, the record information generated for the download process may be ignored. For example, for the record information including the download duration of less than 20 seconds, the terminal may not delete the record information of the download duration of less than 20 seconds included in the terminal on the EPG or the EPG.
- the threshold for example, the download duration is less than 20 seconds

- the purpose of this is: when the terminal does not follow the code rate from low to high, but directly requests the streaming media file of the appropriate bit rate, if the requested bit rate is too high, the terminal cannot correctly download and play the streaming media file. Selecting a smaller bit rate can avoid the problem that the terminal cannot download and play the streaming media file correctly, and the downloaded streaming media data is superior to the attempted downloading scheme according to the code rate from low to high.
- the corresponding code rate when accessing Cellular is 256Kbps
- a Symbian-type terminal has a code rate of 512 Kbps when accessing the WLAN.

- the recommended code rate is 256 Kbps.
- Step 107 The terminal requests to obtain an index file from the streaming server.
- the terminal can request a playlist file from the streaming server.
- the implementation sequence of the step 107 is not limited.
- the terminal may request the index file from the streaming media server after receiving the recommended code rate, or may first obtain the index file from the streaming media server. After requesting the index file, the recommended code rate is received, and the step of acquiring the file I and the step of receiving the recommended code rate may be performed in parallel.

- the URI of the streaming data Since the URI of each code rate block is recorded in the index file, that is, the address of the streaming media data encoded according to each code rate, when the code rate received by the terminal is 256 Kbps, the code can be searched for
- Step 109 The terminal acquires streaming media data according to the determined address, and plays the same, so as to execute the streaming media service.

Description
获取流媒体数据的方法、 设备及系统 本申请要求于 2013 年 04 月 23 日提交中国专利局、 申请号为 201310143304. 9 , 发明名称为 "获取流媒体数据的方法、 设备及系统" 的中国 专利申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及流媒体技术, 尤其涉及一种获取流媒体数据的方法、设备及系 统。
背景技术
近年来, 互联网视频业务迅猛发展,视频内容的流量已占到了整个互联网 流量的一半。谈到互联网视频业务就不得不提到流媒体技术,正是由于流媒体 技术的不断发展才促进了目前互联网视频业务的迅猛发展。目前的流媒体技术 主要有两大类,一类是以 RTSP/RTP(Real Time Streaming Protocol, 实时流传输 协议 /Real Time Transfer Protocol,实时传送协议)为代表的面向连接的流媒体技 术, 另一类是目前主流视频网站采用的无连接的 HTTP ( Hyper Text Transfer Protocol, 超文本传输协议)渐进式下载的流媒体技术。
RTSP/RTP流媒体技术是基于组播的应用层协议的端对端下载技术,其中, RTP用于流媒体数据的传输, RTSP用于统计、 管理和控制 RTP传输, 两者协 同工作, 能够显著提高网络实时数据的传输效率。 但是, RTSP/RTP流媒体技 术还存在以下弊端:
RTSP/RTP 协议栈的逻辑实现较为复杂, 与 HTTP 技术相比, 支持
RTSP/RTP的终端软硬件实现难度较大, 特别是对于嵌入式终端来说尤其难以 实现; 另外, RTSP协议使用的网络端口号 (554)可能被部分用户网络中的防火 墙和 NAT等封堵, 导致无法使用, 虽然有些流媒体服务器可通过隧道方式将 RTSP配置在 HTTP的 80端口上承载, 但实际部署起来并不是特别方便。
HTTP渐进式下载的流媒体技术是指: HTTP终端可以在整个流媒体文件
被下载完成之前可开始流媒体数据的播放, HTTP终端和流媒体服务器如果均 支持 HTTP1.1 , HTTP终端还可从没下载完成的部分任意选取一个时间点开始 媒体的播放。 目前, 主流的视频网站均采用了 HTTP渐进式下载的方式来实现 流媒体的分发。
与 RTSP/RTP技术相比, HTTP渐进式下载的流媒体技术采用了无状态的
HTTP协议, 当 HTTP终端向流媒体服务器请求流媒体数据时, 流媒体服务器 将请求的流媒体数据下发给终端, 但是, 流媒体服务器不记录终端的状态, HTTP终端的每次请求都是一次性独立的会话。
作为最筒单和原始的流媒体解决方案, HTTP渐进式下载方案的显著优点 在于其仅需要维护一个标准的 Web服务器, 其安装和维护的工作量和复杂性 比起专门的流媒体服务器来说要筒单和容易得多。 然而, 其缺点和不足也很明 显, 首先是带宽容易浪费, 当一个 HTTP终端一边从流媒体服务器上下载流媒 体数据, 一边观看内容时, 若没有观看完毕就选择停止观看, 则已经下载完成 的流媒体数据则是对带宽资源的一种浪费。其次,基于 HTTP的渐进式下载仅 仅适用于点播内容, 而不支持直播内容。
有鉴于此, 一种结合了 RTSP/RTP和 HTTP渐进式下载的流媒体技术的 HTTP Adaptive Streaming (以下筒称' 'HAS" )技术应运而生, HAS技术可以大 大提升用户的媒体播放体验, 同时降低了流媒体服务器的技术复杂度; 另夕卜, 基于 HTTP的传送方式提升了流媒体数据在网络设备中的穿透能力, HAS技 术目前已成为流媒体视频行业发展的趋势。
HAS技术的关键是对流媒体文件的切割分块, 每个分块的时间长度相同, 一般为 10秒左右。 在视频编码层, 这意味着每个分块都由若干个完整的视频 GOP组成, 每个分块都有一个关键 I帧, 以此保证每个分块的独立性。
每个分块可分别按照不同的码率进行编码,得到多种码率的分块, 也就是 说, 流媒体服务器在本地存储以不同码率编码的流媒体文件, 同样内容的流媒
体文件, 分别编码得到 128kbps码率的流媒体文件、 256kbps码率的流媒体文 件、 512kbps码率的流媒体文件等。 流媒体服务器还提供索引文件, 所述索引 文件中记录了不同码率的流媒体文件的相关信息。终端从流媒体服务器处下载 索引文件后, 根据其中记录的信息, 请求下载并播放最低码率的流媒体文件, 若该最低码率的流媒体文件的一个分块能够成功下载并播放,表示当前的终端 能力和网络状态能够支持最低码率, 则终端尝试请求更高码率的流媒体文件, 若更高码率的流媒体文件的一个分块也能够成功下载并播放,则继续尝试下载 再高一些码率的流媒体文件,若更高码率的流媒体文件的一个分块不能成功下 载并播放, 则仍继续下载并播放最低码率的流媒体文件, 以此类推, 直至稳定 至某一个合适的码率进行流媒体文件的下载和播放。
以一种基于 HTTP的流媒体传输协议(HTTP Live Streaming, HLS ) 的 HAS技术为例, 将完整的流媒体文件分成多个基于 HTTP的分块, 在开始一 次流媒体会话时,终端首先从流媒体服务器中下载一个包含元数据的 extended M3U playlist文件(即索引文件, 后续筒称 playlist文件 ), 在 HLS规范中, 对 playlist文件的描述如下:
一个 playlist文件是由多个独立行组成的文本文件, 每行由回车或换行标 志区分,每一行中记录了在某一码率下一个分块的 URI以及相应的属性信息, 所述属性信息包括:
BANDWIDTH: 带宽, 必选参数,表示该码率下的分块传输所需的带宽; PROGRAM-ID: 该值是一个十进制整数, 唯一地标识一个在 Playlist文 件范围内的特定的描述;
CODECS: 解码器信息, 可选参数;
RESOLUTION: 分辨率, 表示该码率下的分块在终端播放时所需的分辨 AUDIO: 音频信息, 须与 AUDIO 类别的 " EXT-X-MEDIA"标签中
"GROUP-ID"属性值相匹配, 表示该码率下的分块在终端播放时所需的音频 信息;
VIDEO: 视频信息, 须与 VIDEO 类别的 " EXT-X-MEDIA"标签中 "GROUP-ID"属性值相匹配, 表示该码率下的分块在终端播放时所需的视频 信息。
终端从流媒体服务器下载 playlist文件后, 按照码率从低至高的顺序, 根 据 playlist文件中记载的各不同码率分块的 URI ( Uniform Resource Identifier, 通用资源标识符), 下载并播放流媒体文件的分块, 直至稳定在一个合适的码 率上, 之后持续下载并播放该合适码率的流媒体文件。 在上述的流媒体数据获取方案中, HLS规范中建议每个分片时长约为 10 秒,在按照码率从低至高下载流媒体文件时, 刚开始下载的数十秒流媒体文件 是低码率的流媒体数据, 由于码率越高的流媒体数据的画面细节越丰富, 即图 像质量越好, 因此, 以上述流媒体获取方案下载并播放的前数十秒流媒体数据 的质量较差。 发明内容

为了更清楚地说明本发明实施例的技术方案,下面将对本发明实施例中所 需要使用的附图作筒单地介绍, 显而易见地, 下面所描述的附图仅仅是本发明 的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下, 还可以根据这些附图获得其他的附图。

具体实施方式
本发明实施例提出了一种基于统计的码率自适应的方案,通过对终端和媒 体内容分发设备中的至少一种设备所记录的历史流媒体业务相关信息的统计 分析, 归纳出不同类型的终端在接入各种类型的网络时, 适合下载的流媒体文 件的码率, 以便于终端在进行流媒体业务时 (如终端请求获取基于 HLS的流 媒体数据时), 可直接请求获取适合码率的流媒体文件, 而无需从最低码率开 始尝试下载,避免了现有的流媒体获取方案中前数十秒获取的流媒体数据质量 差的问题, 使得下载并播放的所有流媒体数据的质量都较好。
下面结合说明书附图, 对本发明实施例的方案进行详细说明。
在本发明实施例的方案中,需先统计分析出不同类型的终端在接入各种类 型的网络时,适合下载的流媒体文件的码率,使得终端可根据该合适的码率请 求相应码率的流媒体文件, 因此, 本发明实施例包括网络侧确定码率的过程、 网络侧将确定的合适码率作为推荐值发送给终端的过程,以及终端根据合适的 码率请求流媒体文件的过程, 下面分别加以说明。
实施例一:
如图 1所示, 为本实施例一中获取流媒体数据的方法步骤示意图, 所述方 法主要包括以下步骤:
步骤 101 : 接收各终端上报的在设定时长内执行流媒体业务时的记录信息。 所述记录信息中包括终端的设备类型、终端所接入网络的网络类型和终端 下载流媒体文件的码率。
在本步骤 101的方案中, 归属于同一 EPG ( Electrnic Program Guide, 电 子节目指南) 的终端可定时将本地生成的记录信息上 ^艮给 EPG, 终端也可在 每执行完一次流媒体业务时就上报一次记录信息, 本步骤的执行主体可以是 EPG, 当然也可以是网络侧中其他网元。
终端可在每次执行流媒体业务时 (如终端下载并播放基于 HLS的流媒体 数据的业务), 自动生成一条记录信息, 在其中记录执行该流媒体业务时终端
接入网络的网络类型以及下载的流媒体文件的码率, 同时, 终端还可在记录信 息中添加自身的设备类型。
所述网络类型可以是 WLAN ( Wireless LAN , 无线局域网)类型的网络, 或是蜂窝网 (Cellular ); 终端的设备类型可以是安卓( Android )类型, 或是塞 班(Symbian )类型; 终端下载的流媒体文件的码率可以是 128Kbps、 256Kbps 或是 512Kbps等。
例如, 接收到三个终端上报的五条记录信息如下:
1 )、 Android类型的终端 A在接入 WLAN时, 下载流媒体文件的码率为 512Kbps;
2 )、 Android类型的终端 A在接入 Cellular时, 下载流媒体文件的码率为
256Kbps;
3 )、 Android类型的终端 B在接入 WLAN时, 下载流媒体文件的码率为 256Kbps;
4 )、 Symbian类型的终端 C在接入 WLAN时, 下载流媒体文件的码率为 512Kbps;
5 )、 Symbian类型的终端 C在接入 Cellular时, 下载流媒体文件的码率为 256Kbps
需要说明的是, 在每条记录信息中还可包括下载流媒体文件的下载时长, 由于常规的流媒体业务中,是按照码率由低至高的顺序依次尝试下载并播放流 媒体数据, 因此, 对于下载时长小于门限值的情况(如下载时长小于 20秒), 可视为本次流媒体文件的下载过程是尝试下载, 并不是稳定下载, 则可忽略为 本次下载过程生成的记录信息, 例如, 对于包含的下载时长小于 20秒的记录 信息, 终端可不向 EPG上 或是 EPG删除终端上 ·^艮的包含的下载时长小于 20秒的记录信息。
步骤 102: 根据所述记录信息, 分别确定每种设备类型的终端在其所接入
的各类型的网络下, 所下载流媒体文件的码率。
本步骤 102的执行主体可以是 EPG, 也可以其他能够从 EPG上读取记录 信息并执行本步骤 102的网元。
由于在步骤 101中接收到的各条记录信息中已分别记载了设备类型、网络 类型、 下载流媒体文件的码率之间的关系, 因此, 在本步骤 102中对各条记录 信息进行统计分析,可确定出设备类型和网络类型的组合分别与下载流媒体文 件的码率之间的对应关系。
仍以步骤 101中的五条记录信息为例, 对于 Android类型的终端, 在接入 WLAN时对应的码率为 512Kbps和 256Kbps;
特殊地, 同种类型的终端在接入相同类型网络时, 出现了下载流媒体文件 的码率不同的情况, 在本实施例的方案中, 可选择其中较小的码率, 即对于
Android类型的终端, 在接入 WLAN时对应的码率为 256Kbps。 这样做的目的 是:终端不按照码率由低至高的顺序,而是直接请求合适码率的流媒体文件时, 若请求的码率过高, 终端是无法正确下载并播放该流媒体文件的,选择较小的 码率可以避免终端无法正确下载并播放流媒体文件的问题,同时相对于按照码 率由低至高的尝试下载方案, 下载的流媒体数据更优。
Android类型的终端, 在接入 Cellular时对应的码率为 256Kbps;
Symbian类型的终端, 在接入 WLAN时对应的码率为 512Kbps;
Symbian类型的终端, 在接入 Cellular时对应的码率为 256Kbps。
通过以上步骤 101和步骤 102的方案,网络侧统计出了不同类型的终端在 接入各种类型的网络时, 下载流媒体文件的合适码率, 之后, 当终端向网络侧 请求进行流媒体业务时,网络侧可将与终端的类型以及接入网络匹配的码率作 为推荐值发送给终端。
步骤 103: 接收来自终端的流媒体数据传输请求。
所述传输请求中携带终端的设备类型和终端所接入网络的网络类型。
本步骤 103的执行主体可以是 EPG。
在本步骤 103中, 当某一终端希望执行流媒体业务时, 可向网络侧发起流 媒体数据传输请求, 该传输请求可以是基于 HTTP传输数据包, 在其中相应的 字段中携带终端的设备类型以及当前终端所接入网络的网络类型。
步骤 104: 根据步骤 102确定的内容, 确定在传输请求中携带的设备类型 对应的终端接入传输请求中的网络类型对应的网络时,下载流媒体文件的码率。
例如, 发起流媒体数据传输请求的终端是 Android类型的终端 D , 终端 D 当前接入的网络是 WLAN, 在此情况下, 通过查询步骤 102确定的内容, 终 端 D可直接尝试下载码率为 256Kbps的流媒体文件, 256Kbps的码率为推荐 码率。
步骤 105: 将步骤 104确定的推荐码率发送给终端。
通过以上步骤 103至步骤 105的方案,在终端请求进行流媒体数据的传输 时, 网络侧根据之前的统计结果, 为终端推荐合适的码率, 终端可直接按照接 收到的码率进行流媒体文件的下载,而无需再按照码率由低至高的顺序依次尝 试下载。
步骤 106: 终端接收推荐的码率。
仍以步骤 104的例子来说, Android类型的终端 D在接入 WLAN时, 接 收到推荐的码率为 256Kbps。
步骤 107: 终端从流媒体服务器处请求获取索引文件。
以 HLS为例, 终端可从流媒体服务器中请求获取 playlist文件。
需要说明的是, 本实施例并不对步骤 107 的实现顺序作出限定, 本步骤 107可以是终端在接收到推荐的码率后再从流媒体服务器处请求索引文件, 也 可以先从流媒体服务器处请求获取索引文件后,再接收推荐的码率,还可以并 行执行获取索 I文件的步骤和接收推荐码率的步骤。
步骤 108: 终端从索引文件中确定根据接收到的码率进行编码的流媒体数
据的地址。
由于索引文件中记录了各码率分块的 URI,即按照各码率编码的流媒体数 据的地址, 因此, 当终端接收到的码率为 256Kbps时, 可从索引文件中查找出 以 256Kbps编码的流媒体数据的 URI。
步骤 109: 终端根据确定的地址获取流媒体数据, 并播放, 以此执行流媒 体业务。
通过以上实施例一的方案,终端不再是按照索 I文件中码率由低至高的顺 序依次尝试下载, 而是根据终端的设备类型和接入网络的类型, 统计分析出的 不同类型的终端在接入各网络时推荐的码率,进而在终端请求获取流媒体数据 时,将与该终端的设备类型和当前接入网络类型匹配的码率推荐给终端, 终端 直接按照推荐码率进行流媒体文件的下载,避免了在按照低码率尝试下载时获 取质量较差的流媒体数据,可以从流媒体数据下载的起始就一直获取并播放高 质量的流媒体数据。
实施例一的方案是以终端的设备类型和接入网络的网络类型为基础来进 行码率的统计分析的, 较优地, 本发明实施例也不限于在此基础上, 进一步利 用用户账号信息、 下载的流媒体文件的来源信息、 下载流媒体文件的开始时间 和结束时间、 终端的配置信息等参数来进行统计分析, 下面分别加以说明。
实施例二:
本发明实施例二是以终端的设备类型、接入网络的网络类型和用户账号信 息为基础来进行码率的统计分析的,所述用户账号信息是指注册在流媒体服务 器中, 用于执行流媒体业务的账号信息, 本实施例二的方案如下:
第一步: 接收各终端上报的在设定时长内执行流媒体业务时的记录信息, 包括终端的设备类型、终端所接入网络的网络类型、用户账号信息和终端下载 流媒体文件的码率。
与实施例一的区别在于, 在本实施例二的方案中, 记录信息中额外增加了
用户账号信息,用于表示用户以终端为载体登陆流媒体服务器时注册的用户账 号。
仍以步骤 101中的五条记录信息为例, 在本实施例中, 这五条记录信息内 容如下:
1 )、对于用户 Subscriber 1 ,使用 Android类型的终端 A在接入 WLAN时, 下载流媒体文件的码率为 512Kbps;
2 )、对于用户 Subscriber 1 ,使用 Android类型的终端 A在接入 Cellular时, 下载流媒体文件的码率为 256Kbps;
3 )、对于用户 Subscriberl ,使用 Android类型的终端 B在接入 WLAN时, 下载流媒体文件的码率为 256Kbps;
4 )、对于用户 Subscribed使用 Symbian类型的终端 C在接入 WLAN时, 下载流媒体文件的码率为 512Kbps;
5 )、 对于用户 Subscribed, 使用 Symbian类型的终端 C在接入 Cellular 时, 下载流媒体文件的码率为 256Kbps。
与实施例一类似的, 在记录信息中还可包括下载流媒体文件的下载时长, 对于包含的下载时长小于门限值的记录信息可忽略。
第二步:针对每种设备类型的终端以及该终端在其所接入的各类型网络下, 确定应用各用户账号信息时所下载流媒体文件的码率。
在本步骤中, 利用接收到的记录信息统计出终端、 网络、 用户账号三者与 码率之间的关系。
仍以上一步骤中接收到的记录信息为例, 统计出的结杲为:
Android 类型的终端接入 WLAN 时, 应用用户 Subscriberl 的码率为 512Kbps和 256Kbps;
与步骤 102中的特殊情况类似地,同种类型的终端在接入相同类型网络且 应用同一用户账号时, 出现了下载流媒体文件的码率不同的情况, 在本实施例
的方案中,也可选择其中较小的码率,即 Android类型的终端接入 WLAN时, 应用用户 Subscriberl的码率为 256Kbps;
Android 类型的终端接入 Cellular 时, 应用用户 Subscriberl 的码率为 256Kbps;
Symbian 类型的终端接入 WLAN 时, 应用用户 Subscribe 的码率为
512Kbps;
Symbian类型的终端接入 Cellular 时, 应用用户 Subscribe 的码率为 256Kbps
通过以上两个步骤的方案,网络侧分别统计出了不同类型的终端接入不同 类型的网络, 且应用不同的用户账号时, 下载流媒体文件的合适码率, 之后, 本实施例二的方案可与实施例一的步骤 103至步骤 109的方案类似,区别在于, 在本实施例的方案中, 终端上报的传输请求中还进一步携带用户账号信息, 以 便于利用第二步的统计结果进行码率的推荐。
例如,用户 Subscriberl使用接入 Cellular的 Android类型的终端发起流媒 体数据传输请求, 可向该终端推荐 256Kbps, 之后, 终端直接从索引文件中确 定由 256Kbps编码的流媒体数据的地址, 进而从该地址获取流媒体数据。
特殊地,对于发起流媒体数据传输请求的终端的设备类型和所应用的用户 账号没有统计过的情况,可参考该用户账号在其他类型的终端应用时统计的码 率作为推荐码率, 或是其他用户应用在该类型终端时统计的码率作为推荐值, 较优地, 当以上两种方式得到的推荐码率不同时, 选择其中较小者。
例如,用户 Subscribe 使用接入 Cellular的 Android类型的终端发起流媒 体数据传输请求时, 之前统计结果中没有出现过, 则可参考用户 Subscribe 使用接入 Cellular 的 Symbian类型终端时的码率 256Kbps , 或是参考用户 Subscriberl使用接入 Cellular的 Android类型终端时的码率 256Kbps。
本发明实施例二中各步骤的执行主体与实施例一中相同。
通过本发明实施例二的方案,在实施例一效果的基础上, 进一步细化统计 结果,在同等情况下,应用高优先级用户账号的终端得到的推荐码率高于应用 低优先级用户账号的终端,使得为终端推荐的码率更加适合当前请求的流媒体 业务。
实施例三:
本发明实施例三是以终端的设备类型、接入网络的网络类型和下载的流媒 体文件的来源信息为基础来进行码率的统计分析的,所述来源信息所下载的流 媒体文件的来源, 如视频网站。
本实施例三的方案如下:
第一步: 接收各终端上报的在设定时长内执行流媒体业务时的记录信息, 包括终端的设备类型、终端所接入网络的网络类型、来源信息和终端下载流媒 体文件的码率。
与实施例一的区别在于, 在本实施例二的方案中, 记录信息中额外增加了 来源信息。
仍以步骤 101中的五条记录信息为例, 在本实施例中, 这五条记录信息内 容如下:
1 )、 Android类型的终端 A在接入 WLAN时, 从视频网站 1处下载流媒 体文件的码率为 512Kbps;
2 )、 Android类型的终端 A在接入 Cellular时, 从视频网站 1处下载流媒 体文件的码率为 256Kbps;
3 )、 Android类型的终端 B在接入 WLAN时, 从视频网站 1处下载流媒 体文件的码率为 256Kbps;
4 )、 Symbian类型的终端 C在接入 WLAN时, 从视频网站 2处下载流媒 体文件的码率为 512Kbps;
5 )、 Symbian类型的终端 C在接入 Cellular时, 从视频网站 2处下载流媒
体文件的码率为 256Kbps。
与实施例一类似的, 在记录信息中还可包括下载流媒体文件的下载时长, 对于包含的下载时长小于门限值的记录信息可忽略。
第二步:针对每种设备类型的终端以及该终端在其所接入的各类型网络下, 确定从各来源信息对应的来源处下载流媒体文件的码率。
在本步骤中, 利用接收到的记录信息统计出终端、 网络、 信息来源三者与 码率之间的关系。
仍以上一步骤中接收到的记录信息为例, 统计出的结果为:
Android类型的终端接入 WLAN从视频网站 1处下载流媒体文件的码率为 512Kbps和 256Kbps;
与步骤 102中的特殊情况类似地,同种类型的终端在接入相同类型网络且 从同一来源下载流媒体文件时,出现了码率不同的情况,在本实施例的方案中, 也可选择其中较小的码率, 即 Android类型的终端接入 WLAN从视频网站 1 处下载流媒体文件的码率为 256Kbps;
Android类型的终端接入 Cellular从视频网站 1处下载流媒体文件的码率 为 256Kbps;
Symbian类型的终端接入 WLAN从视频网站 2处下载流媒体文件的码率 为 512Kbps;
Symbian类型的终端接入 Cellular从视频网站 2处下载流媒体文件的码率 为 256Kbps。
通过以上两个步骤的方案,网络侧分别统计出了不同类型的终端接入不同 类型的网络, 且从不同的来源处下载流媒体文件的合适码率, 之后, 本实施例 三的方案可与实施例一的步骤 103至步骤 109的方案类似, 区别在于,在本实 施例的方案中, 终端上报的传输请求中还进一步携带来源信息, 以便于利用第 二步的统计结果进行码率的推荐。
例如, 接入 Cellular的 Android类型的终端请求从视频网站 1处请求下载 流媒体文件, 可向该终端推荐 256Kbps , 之后, 终端直接从索引文件中确定由 256Kbps编码的流媒体数据的地址, 进而从该地址获取流媒体数据。
本发明实施例三中各步骤的执行主体与实施例一中相同。
通过本发明实施例三的方案,也是在实施例一效果的基础上, 进一步细化 了统计结果,在同等条件下,从支持高带宽的视频网站处下载流媒体文件的终 端获得的推荐码率高于从支持低带宽的视频网站处下载流媒体文件的终端获 得的推荐码率, 使得为终端推荐的码率更加适合当前请求的流媒体业务。
实施例四:
本实施例四是将实施例二和实施例三的方案结合在一起, 统计出终端、 网 络用户账号、 来源四者与码率之间的关系, 即:
终端上报的记录信息中同时包含终端的设备类型、终端所接入网络的网络 类型、用户账号信息、 下载的流媒体文件的来源信息和终端下载流媒体文件的 码率, 然后针对每种设备类型的终端以及该终端在其所接入的各类型网络下, 确定应用各用户账号信息时, 从不同的来源处下载流媒体文件的码率。
仍以实施例二和实施例三中涉及的五条记录信息为例,这五条记录信息内 容如下:
1 )、对于用户 Subscriber 1 ,使用 Android类型的终端 A在接入 WLAN时, 从视频网站 1处下载流媒体文件的码率为 512Kbps;
2 )、对于用户 Subscriber 1 ,使用 Android类型的终端 A在接入 Cellular时, 从视频网站 1处下载流媒体文件的码率为 256Kbps;
3 )、对于用户 Subscriberl ,使用 Android类型的终端 B在接入 WLAN时, 从视频网站 1处下载流媒体文件的码率为 256Kbps;
4 )、对于用户 Subscribed ,使用 Symbian类型的终端 C在接入 WLAN时, 从视频网站 2处下载流媒体文件的码率为 512Kbps;
5 )、 对于用户 Subscribed, 使用 Symbian类型的终端 C在接入 Cellular 时, 从视频网站 2处下载流媒体文件的码率为 256Kbps。
对这五条记录信息统计分析后, 得到的结果为:
Android类型的终端接入 WLAN时, 应用用户 Subscriber 1从视频网站 1 处下载流媒体文件的码率为 512Kbps和 256Kbps;
与步骤 102中的特殊情况类似地,同种类型的终端在接入相同类型网络且 应用同一用户账号时,出现了从同一来源处下载流媒体文件的码率不同的情况 , 可选择其中较小的码率, 即 Android 类型的终端接入 WLAN 时, 应用用户 Subscriberl从视频网站 1处下载流媒体文件的码率为 256Kbps;
Android类型的终端接入 Cellular时, 应用用户 Subscriberl从视频网站 1 处下载流媒体文件的码率为 256Kbps;
Symbian类型的终端接入 WLAN时, 应用用户 Subscribed从视频网站 2 处下载流媒体文件的码率为 512Kbps;
Symbian类型的终端接入 Cellular时, 应用用户 Subscribe 从视频网站 2 处下载流媒体文件的码率为 256Kbps。
之后,本实施例四的方案可与实施例一的步骤 103至步骤 109的方案类似, 区别在于, 在本实施例的方案中, 终端上报的传输请求中还进一步携带用户账 号信息和来源信息, 以便于利用统计结果进行码率的推荐。
例如, 对于用户 Subscriberl , 使用接入 Cellular的 Android类型的终端请 求从视频网站 1处请求下载流媒体文件, 可向该终端推荐 256Kbps, 之后, 终 端直接从索引文件中确定由 256Kbps编码的流媒体数据的地址,进而从该地址 获取流媒体数据。
本发明实施例四中各步骤的执行主体与实施例一中相同。
本发明实施例四的方案同时具有实施例二和实施例三的效果。
实施例五:
本发明实施例五是以终端的设备类型、接入网络的网络类型和下载的流媒 体文件的开始时间、结束时间为基础来进行码率的统计分析的, 在所述开始时 间、 结束时间之间的时间段内进行流媒体文件的下载。
本实施例五的方案如下:
第一步: 接收各终端上报的在设定时长内执行流媒体业务时的记录信息, 包括终端的设备类型、终端所接入网络的网络类型、 下载的流媒体文件的开始 时间、 结束时间和终端下载流媒体文件的码率。
与实施例一的区别在于, 在本实施例五的方案中, 记录信息中额外增加了 下载的流媒体文件的开始时间、 结束时间。
仍以步骤 101中的五条记录信息为例, 在本实施例中, 这五条记录信息内 容如下:
1 )、 Android类型的终端 A在接入 WLAN时, 在 20:00~20:30下载流媒体 文件的码率为 512Kbps;
2 )、 Android类型的终端 A在接入 Cellular时, 在 20:00~20:30下载流媒 体文件的码率为 256Kbps;
3 )、 Android类型的终端 B在接入 WLAN时, 在 20:00~20:30下载流媒体 文件的码率为 256Kbps;
4 )、 Symbian类型的终端 C在接入 WLAN时,在 07:00~08:00下载流媒体 文件的码率为 512Kbps;
5 )、 Symbian类型的终端 C在接入 Cellular时, 在 07:00~08:00下载流媒 体文件的码率为 256Kbps。
与实施例一类似的,记录信息中下载流媒体文件的开始时间和结束时间之 间的时间段为流媒体文件的下载时长,对于包含的下载时长小于门限值的记录 信息可忽略。
第二步:针对每种设备类型的终端以及该终端在其所接入的各类型网络下,
在各开始时间和结束时间所表示的时间段内下载流媒体文件的码率。 在本步骤中, 利用接收到的记录信息统计出终端、 网络、 下载时间段三者 与码率之间的关系。
仍以上一步骤中接收到的记录信息为例, 统计出的结果为:
Android类型的终端接入 WLAN时, 在 20:00~20:30时间段下载流媒体文 件的码率为 512Kbps和 256Kbps;
与步骤 102中的特殊情况类似地,同种类型的终端在接入相同类型网络且 同一时间段内下载流媒体文件时, 出现了码率不同的情况, 在本实施例的方案 中, 也可选择其中较小的码率, 即 Android 类型的终端接入 WLAN 时, 在 20:00-20:30时间段内下载流媒体文件的码率为 256Kbps;
Android类型的终端接入 Cellular时,在 20:00~20:30时间段内下载流媒体 文件的码率为 256Kbps;
Symbian类型的终端接入 WLAN, 在 07:00~08:00时间段内下载流媒体文 件的码率为 512Kbps;
Symbian类型的终端接入 Cellular,在 07:00~08:00时间段内下载流媒体文 件的码率为 256Kbps。
通过以上两个步骤的方案,网络侧分别统计出了不同类型的终端接入不同 类型的网络, 且在不同时间段内下载流媒体文件的合适码率, 之后, 本实施例 五的方案可与实施例一的步骤 103至步骤 109的方案类似, 区别在于,在本实 施例的方案中,终端上报的传输请求中还进一步携带下载流媒体文件的当前时 间, 以便于确定当前时间所在的时间段后, 可利用第二步的统计结果进行码率 的推荐。
例如, 接入 Cellular的 Android类型的终端请求从 20: 10开始下载流媒体 文件, 由于 20: 10属于 20:00~20:30时间段, 因此, 可向该终端推荐 256Kbps, 之后,终端直接从索引文件中确定由 256Kbps编码的流媒体数据的地址,进而
从该地址获取流媒体数据。
通过本发明实施例五的方案,在实施例一效果的基础上, 进一步细化了统 计结果, 在同等条件下, 在业务空闲的时间段(如 07:00~08:00 ) 内下载流媒 体文件的终端获得的推荐码率高于在业务繁忙的时间段(如 20:00~20:30 ) 内 下载流媒体文件的终端获得的推荐码率,使得为终端推荐的码率更加适合当前 请求的流媒体业务。
需要说明的是: 本实施例五的方案可以分别与实施例二、 实施例三和实施 例四的方案结合, 具体说明如下:
实施例五的方案与实施例二的方案结合, 统计出终端、 网络、 用户账号、 下载流媒体文件的开始、 结束时间四者与码率之间的关系, 即, 终端上报的记 录信息中同时包含终端的设备类型、终端所接入网络的网络类型、用户账号信 息、 下载流媒体文件的开始时间、 结束时间和终端下载流媒体文件的码率, 然 后针对每种设备类型的终端以及该终端在其所接入的各类型网络下 ,确定应用 各用户账号信息时, 在不同的时间段内下载流媒体文件的码率。
实施例五的方案与实施例三的方案结合, 统计出终端、 网络、 来源、 下载 流媒体文件的开始、 结束时间四者与码率之间的关系, 即, 终端上报的记录信 息中同时包含终端的设备类型、 终端所接入网络的网络类型、 来源信息、 下载 流媒体文件的开始时间、 结束时间和终端下载流媒体文件的码率, 然后针对每 种设备类型的终端以及该终端在其所接入的各类型网络下,从不同的来源,在 不同的时间段内下载流媒体文件的码率。
实施例五的方案与实施例四的方案结合, 统计出终端、 网络、 用户账号信 息、 来源、 下载流媒体文件的开始、 结束时间五者与码率之间的关系, 即, 终 端上报的记录信息中同时包含终端的设备类型、 终端所接入网络的网络类型、 用户账号信息、 来源信息、 下载流媒体文件的开始时间、 结束时间和终端下载 流媒体文件的码率,然后针对每种设备类型的终端以及该终端在其所接入的各
类型网络下, 应用不同的用户账号, 从不同的来源, 在不同的时间段内下载流 媒体文件的码率。
本发明实施例五中各步骤的执行主体与实施例一中相同。
实施例六:
本发明实施例六是以终端的设备类型、接入网络的网络类型和终端的配置 信息为基础来进行码率的统计分析的。所述配置信息可以是终端的软硬件配置 信息, 如软件版本号、 硬件能力值等。
本实施例六的方案如下:
第一步: 接收各终端上报的在设定时长内执行流媒体业务时的记录信息, 包括终端的设备类型、终端所接入网络的网络类型、终端的配置信息和终端下 载流媒体文件的码率。
与实施例一的区别在于, 在本实施例流的方案中, 记录信息中额外增加了 终端的配置信息。
仍以步骤 101中的五条记录信息为例, 在本实施例中, 这五条记录信息内 容如下:
1 )、 Android类型的终端 A在接入 WLAN时, 下载流媒体文件的码率为 512Kbps, 终端 A的软件版本号为 4.0版本, 终端 A的屏幕大小为 4寸;
2 )、 Android类型的终端 A在接入 Cellular时, 下载流媒体文件的码率为 256Kbps, 终端 A的软件版本号为 3.0版本, 终端 A的屏幕大小为 4寸;
3 )、 Android类型的终端 B在接入 WLAN时, 下载流媒体文件的码率为
256Kbps, 终端 B的软件版本号为 3.0版本, 终端 B的屏幕大小为 5寸;
4 )、 Symbian类型的终端 C在接入 WLAN时, 下载流媒体文件的码率为 512Kbps, 终端 C的软件版本号为 4.0版本, 终端 C的屏幕大小为 4寸;
5 )、 Symbian类型的终端 C在接入 Cellular时, 下载流媒体文件的码率为 256Kbps, 终端 C的软件版本号为 4.0版本, 终端 C的屏幕大小为 4寸。
与实施例一类似的,记录信息中下载流媒体文件的开始时间和结束时间之 间的时间段为流媒体文件的下载时长,对于包含的下载时长小于门限值的记录 信息可忽略。
第二步: 在各种配置信息下,针对每种设备类型的终端以及该终端在其所 接入的各类型网络下, 下载流媒体文件的码率。
在本步骤中, 利用接收到的记录信息统计出终端、 网络、 配置信息三者与 码率之间的关系。
仍以上一步骤中接收到的记录信息为例, 统计出的结果为:
版本号为 4.0、 屏幕大小为 4寸的 Android类型的终端接入 WLAN时, 下 载流媒体文件的码率为 512Kbps;
版本号为 3.0、屏幕大小为 4寸的 Android类型的终端接入 Cellular时, 下 载流媒体文件的码率为 256Kbps;
版本号为 3.0、 屏幕大小为 5寸的 Android类型的终端接入 WLAN时, 下 载流媒体文件的码率为 256Kbps;
版本号为 4.0、屏幕大小为 4寸的 Symbian类型的终端接入 WLAN时, 下 载流媒体文件的码率为 512Kbps;
版本号为 4.0、 屏幕大小为 4寸的 Symbian类型的终端接入 Cellular时, 下载流媒体文件的码率为 256Kbps。
通过以上两个步骤的方案, 网络侧分别统计出了在不同的配置下, 不同类 型的终端接入不同类型的网络时下载流媒体文件的合适码率,之后, 本实施例 六的方案可与实施例一的步骤 103至步骤 109的方案类似, 区别在于,在本实 施例的方案中, 终端上报的传输请求中还进一步携带终端的配置信息, 以便于 确定终端当前的配置情况后, 可利用第二步的统计结果进行码率的推荐。
通过本发明实施例六的方案,在实施例一效果的基础上, 进一步细化了统 计结果, 在同等条件下, 配置越高的终端获得的推荐码率越高, 使得为终端推
荐的码率更加适合当前请求的流媒体业务。
需要说明的是: 本实施例六的方案可以分别与实施例二、 实施例三、 实施 例四和实施例五的方案结合
本发明实施例六中各步骤的执行主体与实施例一中相同。
本发明实施例一至实施例六的方案是网络侧对所管辖内的终端上报的记 录信息进行统计的方案,本发明实施例也不限于由媒体内容分发设备(如 MDN (广域媒体内容分发设备)) 向网络侧上报的在设定时长内每次执行流媒体业 务时生成的历史信息,再由网络对接收到的历史信息进行统计后, 为发起流媒 体数据传输请求的终端推荐合适的码率, 下面对此进行说明。
实施例七:
本发明实施例七是以 MDN为例, 说明网络侧利用 MDN上报的历史信息 来统计每种设备类型的终端在其所接入的各类型的网络下,所下载流媒体文件 的码率, 主要内容包括:
第一步:接收 MDN上报的在设定时长内每次执行流媒体业务时生成的历 史信息。
所述历史信息中包括执行流媒体业务的终端的设备类型、该终端所接入网 络的网络类型和终端下载流媒体文件的码率。
需要说明的是, MDN在设定时长内可与多个终端交互进行过流媒体业务, MDN可为每次流媒体业务生成一条历史信息, 较优地, 在每条历史信息中还 可包括终端下载流媒体文件的下载时长,对于下载时长小于门限值的情况, 可 忽略。
第二步: 根据所述历史信息, 分别确定每种设备类型的终端在其所接入的 各类型的网络下, 所下载流媒体文件的码率。
本实施例七的方案与实施例一的方案类似, 所不同的是本实施例中由 MDN向 EPG发送历史信息。
与实施例二、 实施例三、 实施例四、 实施例五和实施例六类似地, 本实施 例中历史信息还可包含用户账号信息、所下载的流媒体文件的来源信息、 下载 流媒体文件的开始时间和结束时间、终端的配置信息中的一种信息或多种信息 的组合, 并将新包含的信息结合实施例七中的设备类型和网络类型进行统计, 此处不再赘述。
本实施例七统计的是 MDN上 4艮的历史记录, 由于 MDN上 4艮的历史记录 不容易被墓改, 因此, 利用本实施例七的方案得到的统计结果的可靠性高。
优选地,本发明实施例还可将实施例一至实施例六与实施例七结合在一起, 由网络侧结合终端上报的记录信息和 MDN上报的历史信息进行统计,来为终 端推荐合适的码率, 一方面, 对于 youtube之类的视频网站不是由 MDN提供 服务的, 以终端上报的记录信息可对这一类情况进行补充; 另一方, 由于终端 的移动性, 终端可能无法及时向网络侧上 4艮记录信息, 此时, MDN上 4艮的历 史信息可对这一类情况进行补充, 完善统计结果。
特殊地,在同等条件下,根据记录信息和历史信息统计得到的码率不同时, 以才艮据记录信息得到的码率为准,历史信息统计结果作为对以记录信息得到码 率方案的补充。
本发明实施例一至实施例七的方案都是由网络侧(如 EPG )对终端和 MDN 中的至少一种设备上报的信息进行统计分析,再将合适的码率推荐给发起流媒 体数据传输请求的终端, 由于用于统计的资源信息多, 可得到包含多种情况组 合的统计结果, 且对于没有统计到的情况, 也可参考其他相近的结果。
优选地,在本实施例一至实施例七的方案中, 网络侧可根据得到的统计结 果生成统计列表, 在其中记载不同类型的终端在接入各种类型的网络时, 下载 流媒体文件的合适码率(若还以用户账号信息、所下载的流媒体文件的来源信 息、下载流媒体文件的开始时间和结束时间和终端的配置信息中的一种信息或 多种信息进行统计分析, 则统计列表中增加相应项), 并将该统计列表主动发
送给当前服务的终端, 由终端在需要请求下载流媒体文件时,读取接收到的统 计列表, 根据自身的实际情况选择合适的码率。
本发明实施例的方案也不限于由终端对本地生成的记录信息进行统计分 析, 具体说明如下:
实施例八:
本发明实施例八的方案是以终端对码率进行统计进而选择合适码率下载 流媒体文件的方案, 如图 2所示, 包括如下步骤:
步骤 201 : 终端确定自身在设定时长内每次执行流媒体业务时生成的记录 信息。
所述记录信息中包括终端所接入网络的网络类型和终端下载流媒体文件 的码率。
终端可在每次执行流媒体业务时生成的记录信息,并将设定时长内生成的 所有记录信息用于统计。 与实施例一中步骤 101的方案类似的, 在每条记录信 息中还可包括下载流媒体文件的下载时长, 对于下载时长小于门限值的情况, 可忽略。
例如, 终端在设定时长内生成的三条记录信息如下:
1 )、 接入 WLAN时, 下载流媒体文件的码率为 512Kbps;
2 )、 接入 Cellular时, 下载流媒体文件的码率为 256Kbps;
3 )、 接入 Cellular时, 下载流媒体文件的码率为 128Kbps。
步骤 202: 终端根据所述记录信息, 分别确定在接入每种类型的网络时, 所下载流媒体文件的码率。
终端对步骤 201中的 3条记录信息的统计结果为:
接入 WLAN时, 下载流媒体文件的码率为 512Kbps;
接入 Cellular时, 下载流媒体文件的码率为 128Kbps。
与实施例一的方案类似的,在接入相同类型网络时, 出现了下载流媒体文
件的码率不同的情况, 可选择其中较小的码率, 以避免终端选择过大的码率而 无法正确下载并播放流媒体文件的问题。
步骤 203: 当终端希望下载流媒体文件时, 确定当前所接入网络的网络类 型。
步骤 204: 终端根据步骤 202的统计结果, 确定在当前所接入网络下, 下 载流媒体文件的码率。
步骤 205: 终端从索引文件中确定由步骤 204确定的码率进行编码的流媒 体数据的地址。
步骤 206: 终端根据确定的地址获取流媒体数据。
与实施例二至实施例六类似的, 本实施例八中, 终端的记录信息还可包含 用户账号信息、所下载的流媒体文件的来源信息、 下载流媒体文件的开始时间 和结束时间和终端的配置信息中的一种信息或多种信息的组合,并将新包含的 信息结合实施例八中的网络类型进行统计, 此处不再赘述。
通过本实施例八的方案, 相对于实施例一得到的效果, 进一步地, 当终端 请求下载流媒体文件时, 可直接根据自身统计结果确定合适的码率,在此情况 下, 终端无需通过网络侧推荐才能获得合适的码率, 可由自身来确定合适的码 率, 筒化了终端从网络侧获取推荐码率的过程,提高了终端进行流媒体业务的 效率。
实施例九:
本发明实施例九还提供一种与实施例一属于同一发明构思下的确定码率 的设备, 如图 3所示, 包括: 信息接收模块 11、 码率存储模块 12、 请求接收 模块 13、 码率确定模块 14和码率发送模块 15 , 其中:
