Front end device and method for realizing pretreatment for video fingerprints at front end

Abstract

The invention discloses a front end device and a method for realizing the pretreatment for video fingerprints at a front end. According to the front end device and the method, a transport stream generation unit is used for generating a transport stream, sending one path of transport stream into an integration unit and sending the other path of transport stream into a video elementary stream obtaining unit; the video elementary stream obtaining unit is used for demultiplexing the transport stream to obtain a video elementary stream and sending the video elementary stream into a fingerprint position information adding unit; the fingerprint position information adding unit is used for embedding analyzed video fingerprint position information into the video elementary stream; a fingerprint part coding unit is used for generating fingerprint part coding information; and the integration unit is used for multiplexing and integrating the video elementary stream of the video fingerprint position information, the transport stream and the fingerprint part coding information, so as to generate a new transport stream. According to the front end device and the method, the working consumption of the terminal is reduced, and the treatment time of the terminal for the video fingerprints is shortened.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a front-end device and a method for realizing video fingerprint preprocessing at the front-end. Background technique [0002] The continuous progress and wide application of digital technology have promoted the rapid development of the digital TV media industry, and the use of digital technology to record, store, transmit and play digital TV programs has become quite popular. The digitization of TV programs has greatly reduced the material and labor costs of the entire industry, and brought more digital-specific effects. However, security issues have always been a major problem plaguing digital television programs. For the copyright holders of digital TV programs, piracy brings great economic losses to them every year. The sound development of digital TV programs requires that the industry must have a complete and sound security management mechanism, otherwise piracy ...

However, security issues have always been a major problem plaguing digital TV programs

[0004] The traditional video fingerprint technology is to complete all video fingerprint processing operations including video fingerprint preprocessing and video fingerprint embedding in the terminal. Nearly saturated, if the video preprocessing operations such as video fingerprint position generation and video fingerprint encoding are performed, the terminal processor will be overloaded, which will affect the efficiency of video playback, and it is difficult to guarantee the real-time performance of video playback
