Video device, video camera recording device and video & audio editing system

Abstract

The invention provides a video device, video camera recording device and video and audio editing system. Wherein, the audio and video frequency editing system comprise: a data editing unit, a displaying output unit, a control input unit, and an iVDR hardware driver; the data editing unit is used to edit the video and audio data and connect with the display output unit; the control output unit is connected with the data editing unit which achieves the signals for controlling the input unit and operates corresponding data editing; the iVDR hardware driver connects with the data editing unit by a serial ATA interface. The invention realizes the digitalized program collecting, REC and editing.

Description

technical field [0001] The invention relates to a broadcast television system, in particular to an editing system and a camera-recording integrated device. Background technique [0002] Since the invention of television, magnetic tape has been playing an important role as a medium for recording TV signals and a carrier for TV programs, and the tape-based linear recording and editing process has been used until now. The linear recording and editing refers to that the recording and editing sequence of the television signal strictly corresponds to the physical location of the tape, and once the program is recorded, the sequence cannot be changed. [0003] The tape-based linear editing is to copy the segments determined in the material tape to another tape according to the program requirements. During editing, it is necessary to copy (edit) the sequence of the segments according to the program requirements, so as to complete the editing of the program. , the sequence of program...

AI Technical Summary

Problems solved by technology

[0006] It can be seen from this that the existing program production equipment cannot directly provide program data that can be recognized and processed by the computer. The intervention of the editing system only reduces the number of tape duplications, and the loss of the program signal is still accompanied by the tape duplication, so the non-linear editing equipment cannot completely solve the problem of signal loss in the TV program editing process; further, the material on the tape needs to be Real-time capture to the nonlinear editing system with a ratio of 1:1, but in actual operation, it often needs to be downloaded in units of shots, so it takes more time

[0007] To sum up, the existing equipment cannot provide program data that can be directly recognized by the computer in the process of TV program acquisition and recording, so that there is still a process of storage medium conversion in the existing TV program production process, which in turn leads to the loss of TV program signals And the cumbersome and complicated program production process reduces the efficiency of program production
