Abstract
The invention discloses a stream media play method and terminal. The method comprises the steps of: obtaining a media stream data according to a predetermined work mode identifier; parsing the media stream data to obtain an original coding data of the media stream data and relative auxiliary information; judging whether or not the playing media stream needs a buffer zone according to the predetermined work mode identifier, if so, buffering the original coding data of the media stream data according to relative auxiliary information, decoding to play the original coding data processed in the buffer zone; if not, directly decoding to play the original coding data parsed. The invention obtains the media stream data and processes corresponding play processes by different methods through the predetermined work mode identifier, which realizes differentiated play of the media stream data in the buffer zone or out of it. The play terminal is adapted to different stream media server agilely, which ensures play quality and speed, saves the resource of the play terminal and improves intercommunication capacity of the play terminal.
Description
Technical field
(Internet Protocol Television, IPTV) field particularly relates to a kind of flow media playing method and terminal to the present invention relates to Web TV.
Background technology
When coming the flow-medium performance of automatic network, the IPTV terminal plays to use two functional modules: network receiver module and playout software module.The broadcast of flow-medium performance divided for three steps, and the first step is a receiving media flow data from the streaming media server; Second step was the pretreatment operation of the media stream data that receives being carried out out of order rearrangement, dithering process, packet loss processing etc., and the media stream data pretreatment operation need be used buffering area; The 3rd step was that media stream data is decoded and play.Wherein, the described first step is realized that by the network receiver module the 3rd step was realized by the playout software module that second step was to be realized by network receiver module or playout software module according to the host-host protocol decision that streaming media server adopts then.
The media stream data host-host protocol that different streaming media servers adopts is also inconsistent, as: the streaming media server that has adopts RTP (Real Time Transport Protocol, RTP), the streaming media server employing User Datagram Protoco (UDP) that has (User Datagram Protocol, UDP).If adopt Real-time Transport Protocol to carry out the media stream data transmission, the network receiver module can carry out the media stream data pretreatment operation according to the information that Real-time Transport Protocol carries when the receiving media flow data, do not need the playout software module to be provided for the buffering area of medium flow data; If adopt udp protocol to carry out the media stream data transmission, then can only carry out the pretreatment operation of media stream data according to the information that media stream data itself carries, and this can only be realized by the playout software module, therefore the playout software module need possess the function that buffering area is provided, to realize the media stream data pretreatment operation.Therefore, the playout software module will consider whether need to be provided with buffering area with realization media stream data pretreatment operation when designing and developing, thereby can be adaptive with specific streaming media server.
Stream media terminal is having following two kinds of schemes to the media stream data pretreatment operation at present: a kind of scheme is in the playout software module buffering area to be set, no matter dock with the streaming media server that adopts which kind of media stream data host-host protocol, the playout software module all distributes buffering area to realize the pretreatment operation of media stream data.But at the streaming media server that need in the playout software module, not carry out the pretreatment operation of media stream data to this class of employing Real-time Transport Protocol, can distribute buffering area too one time, therefore the media stream data pretreatment operation can be carried out one time, and this must cause the significant wastage of resource more.Second kind of scheme is that buffering area is not set in the playout software module, promptly do not carry out the pretreatment operation of media stream data in the playout software module.But the playback terminal that adopts this scheme is when docking with the streaming media server that adopts udp protocol to carry out the media stream data transmission, owing to do not carry out the pretreatment operation of media stream data, media stream data may be chaotic, has a strong impact on the result of broadcast of Media Stream.
By technique scheme as can be seen, just need when the development and Design of streaming media playing terminal at present to consider that playout software module and particular network receiver module are arranged in pairs or groups just can realize adaptive to specific streaming media server, there is great coupling between playout software module and the network receiver module, cause the playout software module in the streaming media playing terminal that the Media Stream that needs the media stream data buffering and do not need Media Stream to cushion is all carried out same processing, can't differentiating and processing, make stream media terminal can only play the flow-medium performance that specific streaming media server provides, the intercommunication poor performance of stream media terminal causes the wasting of resources or has a strong impact on result of broadcast.
Summary of the invention
The purpose of this invention is to provide a kind of flow media playing method and terminal, the broadcast of the flow-medium performance that realization provides the various flows media server, make same streaming media playing terminal can realize to needing buffering area and not needing the various flows media server of buffering area to dock and realize high-quality, at a high speed result of broadcast, the intercommunication ability of enhanced flow media broadcast terminal improves resource utilization.
