Audio and video data transmission method and device

Abstract

The invention provides an audio and video data transmission method and device. The audio and video data transmission method comprises an audio and video pause step and an audio and video data receiving step, which are executed at the same time, the receiving step comprises: a step of inquiring an effective code stream frame from a sending end; a step of judging whether the code stream frame is effective; a step of inquiring a corresponding address space from a buffer queue according to the length of the code stream frame, if the code stream frame is effective; a step of judging whether the address space is enough; a step of recording the type and the length of the code stream frame, if the address space is enough; and a step of writing the code stream frame in the buffer queue. The invention further provides an audio and video data transmission device adopting the transmission method. When audio and video play is paused, audio and video data are stilled received by controlling the buffer queue, thereby optimizing the data transmission efficiency when effectively improving the use efficiency of the buffer queue, and continuous data can be provided for a decoding end to guarantee the play smoothness and improve the user experience.

Description

technical field [0001] The invention relates to the field of multimedia data transmission, in particular to an audio and video data transmission method and a transmission device. Background technique [0002] With the growing cultural industry and emerging mobile Internet devices, people are getting used to watching multimedia audio and video programs on mobile or Internet devices. Generally, the mobile terminal receives the audio and video data from the data sending end, and transmits the audio and video data to the decoder in time, and then displays the decoded audio and video data. This process requires the audio and video data transmission device to ensure that the received The audio and video data are delivered to the decoder for decoding and playback in real time as much as possible. [0003] The existing solution is that after the terminal device reads remote data or local data, the read data is directly transmitted to the decoder for decoding and then playing. If th...

[0003] The existing solution is that after the terminal device reads remote data or local data, the read data is directly transmitted to the decoder for decoding and then playing. If the playback of audio and video is suspended, the buffered data at the receiving end will also be suspended. data, and then receive the data when the playback is started, so that the synchronous operation of playing audio and video and receiving data will affect the efficiency of data transmission, so that the cache cannot receive audio and video data continuously in real time. When the remote communication is not smooth or the local reading fails, then As a result, the inability to continuously provide audio and video data to the decoder will also result in poor audio and video playback, seriously affecting user experience
