A kind of ts stream transmission method and related device

Abstract

The invention discloses a TS stream transmission method and a related device. The method comprises the steps of creating a synchronizing time signal of which the high level duration is equal to the preset high level duration; generating at least one TS packet for transmitting the TS stream, wherein each TS packet of the at least one TS packet includes a synchronizing first byte and an effective TV signal bit; sending the at least one TS packet to a TS stream receiving device according to the synchronizing clock signal, wherein the synchronizing first bit of the TS packet or one effective TV signal bit is sent at the high level period of the synchronizing clock signal. With the adoption of the method, the TS transmission efficiency can be increased, and a TS stream transmission signal wire can be simplified.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a TS stream transmission method and a related device. Background technique [0002] Digital TV technology is a technology developed on the basis of analog TV technology, and it is the crystallization of the highly integrated development of modern electronic technology, communication technology and computer technology. In recent years, with the development of the economy and the improvement of people's requirements for TV programs, digital TV has developed rapidly. Transport Stream (Transport Stream, TS) is a data stream with a certain digital encapsulation format, which is used to package basic audio, video streams and other data. Its design purpose is to allow digital video and digital audio to be multiplexed and output synchronously. It is mainly used in Digital television broadcast programs delivered in real time. In order to synthesize one or more audio, video or...

Problems solved by technology

[0003] At present, the TS stream is sent from the demodulator to the decoder in the set-top box usually using a multi-line serial transmission method, which needs to transmit valid signals, synchronization signals, clock signals and TS packets, so that the receiving end is at a high level when the synchronization signal , and the effective signal is high level, the data in the TS packet is extracted according to the received clock signal, and the data in the TS packet signal is not extracted when the effective signal is low level, which requires four signal lines to transmit separately Valid signal, synchronization signal, clock signal and TS packet four kinds of signals can make the receiving end extract the TS packet accurately and completely, which brings the problem of low TS stream transmission efficiency and many transmission signal lines
