Abstract

The invention discloses a dot matrix fingerprint generation method, equipment and system. The dot matrix fingerprint generation method includes the steps that audio and video information sent by front-end equipment is received by terminal equipment, fingerprint information is extracted from the audio and video information and analyzed to acquire fingerprint content including preset fingerprint display types, and a dot matrix corresponding to the terminal equipment is worked out according to the preset fingerprint display types, embedded into a video layer and displayed. In this way, the fingerprint information is displayed in the form of the dot matrix, and therefore safety of the fingerprint information is improved.

Description

technical field [0001] The invention relates to digital technology, in particular to a method, device and system for generating lattice fingerprints. Background technique [0002] With the continuous progress and wide application of digital technology, the rapid development of the digital TV media industry has been promoted. The use of digital technology to record, store, transmit and play TV programs has become quite popular. Moreover, the digitization of TV programs has greatly reduced the overall The industry's material and labor costs, and bring more digital-specific effects. However, the security problem of the digital TV system has always been a big problem that plagues digital TV programs. [0003] Although the digital TV reception technology is perfect and has been widely used in digital TV systems around the world, this system only protects the transmission process of TV programs, and once the TV programs are decrypted and output, the protection is broken. In orde...
