VIDEO ENCODING SYSTEM PROVIDED WITH TWO OR MORE INDEPENDENT ENCODING CHAINS FOR DYNAMICALLY SELECTIVELY PERFORMING REDUCED SIZE OR FULL SIZE REPRODUCTION

摘要

PROBLEM TO BE SOLVED: To efficiently edit encoded video signals, since there are cases where a designer of video editing applications is requested to deal with more extensive kinds of encoded video data including data encoded by time estimation.;SOLUTION: A first encoding chain generates encoded video data decodable by itself, and acquires a source video sequence of reduced size sufficient for supporting functions of real-time reproduction and display in a video editing application. A second encoding chain generates encoded data of the remaining data, and acquires a source video sequence of full size display by decoding the data together with the encoded video data of the first encoding chain. Since the output of the first encoding chain is stored in a memory of file structure, and can be accessed independently of the output of the second chain, real time decoding and regeneration become possible.;COPYRIGHT: (C)2007,JPO&INPIT
