Embodiment Construction

[0048] Referring to the accompanying drawings, the following non-limiting examples will explain the technical solution of the present invention in more detail, so that those skilled in the art can better understand the present invention.

[0049] In order to realize the synchronization of audio and video only by simple processing at the receiving end, the present invention proposes a method based on transmission stream synchronization. Its basic process is as figure 1 shown.

[0050] As the most mature digital video solution today, MPEG-2 has been generally accepted, deployed and operated by chip designers, equipment manufacturers and operators. Since the TS stream has a strong ability to resist transmission errors, and in order to make better use of existing equipment and networks, a synchronization method based on the TS stream can be used.

[0051] The TS packet is of fixed length, and its packet length is 188Bytes. A TS packet is composed of a 4Bytes connection header, ...

Abstract

The invention relates to a stereo audio and video stream data coding transmission method and system based on transmission streams. The invention comprises: a. Perform camera picking up to gain binocular audio and video data before synchronous compression and multiplex respectively in synchronous control; b. respectively perform envelopment in the synchronous control for transmission stream; c. perform secondary multiplex coding in transmission stream synchronous control, so as to gain single data stream; d. follow real-time transmission protocols to perform envelopment transmission and receive feedback adjusting; f. in the transmission service quality control, the invention can perform real-time transmission protocol de-envelopment and feedback information; g. de-multiplex to gain transversal binocular audio and video data; h. in synchronous monitoring condition, perform audio and video data de-compression and de-multiplexing; i. A display apparatus realizes stereo playing. The invention supports audio and video coding, such as MPEG-1 / 2 / 4, VC1, H263, H.264 and etc, as well as such transmission methods as wireless, cable, time division multiplex, block transmission and so on. The invention can realize remote stereophonical reoccurrence of local audio / video, and is simple, universal and reliable.

Description

Technical field: [0001] The invention relates to a digital coding transmission method and system of stereo audio and video, in particular to a transmission stream-based digital coding transmission method and system of stereo audio and video. Background technique: [0002] With the advancement of science and technology, audio has developed from analog and mono to digital and surround sound; at the same time, video images have also developed from analog, black and white, and CRT small screens to digital, color, and flat screens, thereby better satisfying human needs. The need for audio-visual enjoyment. [0003] Compared with traditional monocular video, stereoscopic video (binocular video) increases the depth information representation of the scene, which can enhance the realism and fidelity of visual effects. Stereo audio and video technology can be widely used in information services such as multimedia news release, online live broadcast, online advertising, e-commerce, vi...
