PROBLEM TO BE SOLVED: To shorten the setting time of the condition for data compression by generating the file for control of data compression while utilizing a recorded file for control based on the result of compassion between a remaining data compression condition and a change condition when the condition of data compression is changed in the case of setting the target data amount of data compression for the unit of prescribed blocks. SOLUTION: A main controller 11 controls the operation of the entire video signal processor 7 by communicating data with a supervisor 3 through a network. When the change of the target bit is required, the amount of bits allocatable to video data in the range instructed by an operator is successively distributed to the respective frames similarly to the setting process of the first target bit amount. Afterwards, an encoding control file is prepared based on the reset target bit amount. Thus, the file for encoding control is generated while variously changing picture quality as needed and according to this file, the data compression of video data is enabled. |
