Abstract

The invention discloses a VBR sending method in a TS packaging format, and the method comprises the following steps: S10, carrying out the TS format packaging of audio and video compressed data according to a compression code rate; S20, packaging the code rate according to the TS format, and carrying out UDP packaging and sending; and S30, when the UDP is packaged and sent, filtering empty packets packaged in a TS format, specifically, according to a TS format specification, analyzing a TS Header, directly filtering packets of which the PID is 0x1FFF before the UDP is sent, and not carrying out UDP packaging and sending. According to the invention, the VBR sending problem of the TS packaging format can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of real-time audio and video processing, and in particular relates to a VBR sending method in a TS encapsulation format. Background technique [0002] In the audio and video processing system in the field of radio and television, the compressed audio and video data is generally packaged in the TS (Transport Stream) encapsulation format and the network UDP (User Datagram Protocol, User Datagram Protocol) for real-time stream transmission between systems. Sending UDP packets is generally sent through a constant bit rate (Constants Bits Rate, CBR). Even if the audio and video encoding is a dynamic bit rate (Variable Bit Rate, VBR), the highest bit rate of the encoded dynamic bit rate is used as the fixed bit rate. send, thus creating unnecessary network traffic. [0003] Due to the fixed transmission according to the highest code rate of encoding, the encoded data actually generated per second generally does n...
