Embodiment Construction

[0030] see figure 1 As shown, a grouping method for streaming media transmission in an intercom system includes the following steps:

[0031] Step 10, at the encoding sending end of the intercom system, encode the collected video to obtain single-frame video frames; the collected audio PCM data is divided into individual frame-by-frame audio frames according to the specified time length;

[0032] Step 20, split the video frame and audio frame of a single frame into multiple video data packets and multiple audio data packets of specified size respectively, and send each video data packet and each audio data packet with a data packet header To the decoding end of the intercom system; the data packet header includes the following information: frame type, frame mark, frame number, data packet number and the total number of packets under the frame number; the frame type includes video and audio, so Described frame sign comprises common frame and key frame, and described frame sequ...

Abstract

The invention provides a packing method for streaming media transmission in an intercom system. The method comprises the following steps of firstly, encoding acquired videos to acquire video frame of gradual single frames, and dividing the acquired audio PCM (pulse-code modulation) data into audio frame of gradual single frames according to appointed time period; secondly, after adding one data packet head to each video data packet and each audio data packet respectively, transmitting each video data packet and each audio data packet to a decoding terminal; and finally, analyzing the data packet head by the decoding terminal, wherein if the video data packet is lost, pausing until complete video key frames are received, if the audio data packet or audio frames are lost, automatically complementing the packet or the frames, and when video play is paused, if the audio frames or the audio data packet is not lost, the audio data can be normally played. The problems of much redundant data, mosaic videos and interrupted sound in a short time in a streaming media transmission process of the intercom system are solved, and the smoothness and the play effect of streaming media transmission in the intercom system are improved.

Description

【Technical field】 [0001] The invention relates to a grouping method for streaming media transmission in an intercom system. 【Background technique】 [0002] The streaming media transmission of the intercom system generally encapsulates the audio and video encoding in the following way: the original audio data is obtained at the audio collection end and encoded into audio frames; the original video data is obtained at the video acquisition end and encoded into video frames; Audio frames and video frames are encapsulated in a certain media file encapsulation format, such as ASF, MP4, TS, etc., to obtain encapsulated frames. The encapsulated frame, a specific frame, can contain a complete video frame (or audio frame); it can also contain a complete n-frame video frame (or audio frame); it can also contain only a complete video frame ( or audio frame). Taking TS encapsulation as an example, there may be the following order: TS packet 1 (part of video frame 1), TS packet 2 (part...
