Problems solved by technology

In fact, at present, various terminals such as home computers, set-top boxes and handheld devices provide decoding support for mainstream audio and video encoding formats such as H.264, MPEG-4, AAC, MP3, etc., but due to the supported encapsulation formats and transmission protocols Each is different, often making the terminal player unable to play directly

Embodiment 1

[0056] control figure 1, an adaptive playback unit 110 is set on the network terminal 100, which forms an adaptive playback system with the original media stream server 200. The network terminal 100 in this embodiment is a fixed terminal and a mobile phone. The player 130 on the network terminal 100 sends a play request to the adaptive play unit 110, and the adaptive play unit 110 receives the play request sent by the network terminal 100, and obtains the original media stream attribute information from the original media stream server 200, and performs an The stream attribute information generates transcoding conversion information, and sends the transcoding conversion information to the network terminal 100. The network terminal 100 selects a suitable code rate according to the transcoding conversion information, and plays the media stream through the player 130 of the terminal.

[0057]

Embodiment 2

[0059] For the above-mentioned embodiment, further designs can be made according to the functions of the adaptive playback unit 110. The preferred design is that the adaptive playback unit 110 is composed of a proxy server 111 and a transcoding module 112, and the transcoding module can be based on its The completed functions can be optimally set as the following software unit modules: player detection unit module, pre-slicing unit module, media stream conversion unit module and merging unit module, so as to better classify and process data. The steps for the network terminal to request playback adaptation are as follows: figure 2 .

[0060] For example, the request by the terminal 100 is received by the proxy server 111 in the adaptive playback unit 110, and the proxy server 111 obtains the original media stream attribute information to be played from the original media stream server 200 according to the address information in the playback attribute information; or The vide...

Embodiment 3

[0063] The adaptive playback unit 110 in this embodiment is composed of a proxy server 111 and a transcapsulation module 112. The specific process for the network terminal to request playback adaptation is as follows: image 3 .

[0064] 1-2. The network terminal 100 sends a request to visit http: / / example.com / a.flv through the browser 130 on it, and the request is received by the local proxy server and forwarded to the encapsulation module 112, which is known through detection. The flv media stream requested by the terminal is not supported by the terminal, that is, the playback attributes are different from the attribute requirements of the network terminal player for the original media stream.

[0065] 3-4. The transcapsulation module requests http: / / example.com / a.flv from the media streaming server through the proxy server to request the header data.

[0066] 5. The media streaming server returns the data at the beginning of a.flv.

[0067] 6. The proxy server 111 forwa...

Abstract

The invention relates to a self -adapting stream-media play method and a self-adapting play unit. Playing steps are as following: a self-adapting play unit arranged on a network terminal receives a playing request sent by the network terminal, the self-adapting play unit acquires an original medial stream and corresponding original medial stream attribute-information from an original media stream server, the self-adapting play unit generates transcoding exchange information from original medial stream attribute-information which is in different play formats from network terminal player, and the transcoding exchange information is send to the network terminal by the self-adapting play unit, the network terminal chooses appropriate code rate according to the transcoding exchange information and media stream playing is proceed through a player of the network terminal. The system includes the network terminal, the self-adapting play unit and the original media stream service. The self-adapting stream-media play method and the self-adapting play unit has the advantages that demand that a terminal supports to play all kinds of network videos which existed in internet with different transmission protocols and different package formats is met.

Description

[0001] technical field [0002] The invention relates to streaming media technology, in particular to an adaptive streaming media playing method and an adaptive playing unit thereof. Background technique [0003] Multimedia has become an indispensable and important part of people's work and study, and plays an increasingly important role in people's work, study and life. Multimedia has its applications in many fields. In response to people's different needs for multimedia services in daily work and life, some standardization organizations have proposed a variety of audio and video coding standards and different audio and video packaging formats for different business needs in society. For example, the H.263 standard proposed for video telephony and video conferencing services; the Mpeg2 standard proposed for DVB, HDTV and DVD; the MPEG4 standard developed for streaming media services in the network; and the network-friendly H. 264 standard, etc. [0004] However, since va...
