Problems solved by technology

[0002] The recording systems of existing video recorders all use single-screen analog signal recording, and their definition is mostly 250 lines, so the definition of existing video recorders is relatively poor, and they cannot display and record several required pictures at the same time, and add anti-counterfeiting In addition, the analog signals and electromagnetic signals used by existing video recorders have a short storage time

Embodiment Construction

[0014] Such as figure 1 As shown, the multi-picture segmentation processing technology uses image interception and splicing technology, which is to intercept a part of the required image information on each video input screen, and then splicing multiple image information to form a single image. The image information of multiple channels is displayed synchronously on the screen.

[0015] Such as figure 2 As shown, the superposition principle of video anti-counterfeiting watermark is to use superimposition technology on the basis of the original video signal to superimpose a luminance signal and display the character on the image. The character takes the image as the background, and the character changes with the image. The light and dark changes, the characters and images are integrated, and the watermark is superimposed on the center point of the connection of the multi-screen.

[0016] The digital codec audio signal processing system is composed of an integrated chip capab...

Abstract

The multiple-picture violence-preventing CD directly recording system is one electronic video and audio CD recording system. The direct CD recording system consists of multiple-picture separating system, anti-fake watermark superposing system, digital audio signal coding and decoding system, and digital video signal coding and decoding system. During multiple-picture separation and anti-fake watermark superposing, several video signals are synchronized and displayed simultaneously and one mark with image background is added to the picture joint. The A / D converter converts the analog video and audio signal into digital signal, and the video and audio codec then performs the coding, decoding and compressing processing of the converted signal in the MPEG-1 or MPEG-2 compression mode and the PCI / IDE converter finally converts the signal transmission mode. The signal input via IDE bus is recorded in the burning machine.

Description

technical field [0001] The invention relates to a multi-picture anti-tampering disc direct recording system, which belongs to an electronic audio-visual disc recording system for video recorders. Background technique [0002] The recording system of existing video recorders all adopts single-screen analog signal recording, and its definition is mostly 250 lines, so the definition of existing video recorders is relatively poor, and it is impossible to display and record several required pictures at the same time, and add anti-counterfeiting In addition, the analog signals and electromagnetic signals that existing video recorders all adopt have a short storage time. Contents of the invention [0003] The purpose of the present invention is to provide a multi-picture anti-counterfeiting optical disc direct recording system with clear video signals, multi-picture synchronous display, anti-counterfeiting marks, and synchronous real-time video recording. [0004] The present in...
