Problems solved by technology

However, after the RS code is determined, the code rate and error correction rate of the transmitted data have been determined. When the RS code is used to encode and decode video data, the adaptability to the code rate of the transmitted video data is not ideal.

Abstract

The invention discloses a video data transmission method and system. The method comprises the following steps that: a video data transmitting end performs Reed-Solomon (RS) coding on each frame of image data of a first system format in video data, and converts the image data being subjected to RS coding into transmission data of a second system format; and when the transmission data are received, a receiving end converts the transmission data into the first system format, performs RS decoding on the transmission data of the first system format to restore the transmission data into the image data, and integrates the received image data into the video data. According to the video data transmission method and system, the transmitting end performs RS coding on the image data of the first system format, and converts the image date into the second system format to transmit the image data of the second system format. The receiving end receives the data of a second system, converts the data of the second system into the first system format, and performs RS decoding on the data of the first system forma, so that the first and second system formats can be selected according to a code rate of image data to be transmitted and a transmission requirement; an error correction rate is increased; and an anti-jamming capability is enhanced.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a video data transmission method and system. Background technique [0002] With the popularization of the Internet and the development of social informatization, and with the development of video technology, video services are widely used, such as video chat, video surveillance, home guards, etc., when transmitting video data, if The image data packet loss will directly affect the user experience. [0003] At present, forward error correction technology is mostly used in the transmission of video data. Forward error correction is also called forward error correction code (ForwardErrorCorrection referred to as FEC), which is a method to increase the reliability of data communication. In a one-way communication channel, once an error is detected, its receiver has no right to request transmission. FEC is a method of using data to transmit redundant information. When an ...
