PROBLEM TO BE SOLVED: To provide a rational picture processing system in which the implementation of the picture processing can be ensured, and picture deterioration can be reduced to the minimum in a simple constitution. SOLUTION: Plural picture data encoded by an arbitrary inter-frame encoding system are inputted to first picture recording and reproducing devices 11-i , converted into encoded data in a prescribed inter-frame encoding system to be handled by a second picture recording and reproducing device 14 by corresponding encoding system converting devices 12-i , appropriately selected by a switch device 13, and the necessary parts are recorded in the second picture recording and reproducing device 14. An edit processing is operated to the picture data recorded in the second picture recording and reproducing device 14 by a picture editing device 15. The inputted picture data are decoded and encoded by the above mentioned prescribed system by the encoding system converting devices 12-i , and at that time, information at the time of original encoding such as inverse quantization precision is used for new encoding so that the conversion of the encoding system without any picture quality deterioration can be attained. |
