Embodiment Construction

[0044] The present invention is described in detail below in conjunction with embodiment, the present invention is described in detail below in conjunction with embodiment, a kind of AVS encoding network transmission method that is used for hard disk video recorder and video server, comprises: determine RTP agreement to transmit AVS code stream, AVS code stream is valid in RTP The specific format of the payload area, the format of encapsulation and parsing; there are three ways to send RTP packets to the Network Abstract Layer Unit (NALU for short): only one frame (ONP) is loaded in one RTP, and one frame is loaded in an RTP packet. Containing multiple frames (MNP), one frame is divided into multiple fragments and entered into RTP packets (ONFP); three transmission methods, they have a common unit header network abstraction layer unit data header structure (NALU Head, NH), A total of 2Bytes, the values ​​defined by the three sending methods are as follows:

Abstract

The invention discloses an AVS coding network transmission method for a video recorder and a video server, comprising: determining a RTP protocol to transmit AVS code stream which includes a particular format in a RTP effective load region, three sending means for RTP data packets to send a unit data head of a network abstraction layer are as follows: one RTP only loads one frame of ONP format sending; one RTP packet comprises a plurality of frames of MNP format sending; one frame is divided into a plurality of fragments which are respectively placed into ONFP format sending in the RTP packet and formats for package and analysis. The invention realizes packing format of AVS on RTP transmission and utilizes the RTP protocol to accomplish network transmission of the AVS stream media, such that AVS coding can be applied effectively in the surveillance field, in particular, in network surveillance, and the network surveillance can be realized rapidly and securely in the technical field of prevention and surveillance for security.

Description

Technical field [0001] The invention relates to the technical field of networked security monitoring, in particular to an AVS encoding network transmission method used for hard disk video recorders and video servers. Background technique [0002] Video surveillance has developed through the first generation of analog surveillance, the second generation of semi-digital surveillance, and now the third generation of full digital network surveillance. Network surveillance has become the mainstream technology in the field of security monitoring. Digital network monitoring is closely related to digital encoding of video images. There are two main series of international audio and video encoding and decoding standards: MPEG series standards formulated by ISO / IEC JTC1; H.26x series video encoding standards formulated by ITU for multimedia communications and G. 7 series audio coding standard. At present, there are four source coding standards that the audio and video industry can ch...
