Mosaic video flow producing method for e.g. navigation in set of video data, involves constructing video flow forming mosaic flow by inserting extracted base segments of original video flows in same extraction order

摘要

The method involves obtaining several original video flows (TB1-TB4) with each flow being coded according to a format in which the flow is composed of a standard edition. Base segments (SLHB1-SLHB4, SLDB1-SLDB4) of each edition are extracted according to a predetermined extraction order and a number of obtained flows. A video flow forming a mosaic flow (MS) is constructed by inserting the extracted segments in same extraction order. Independent claims are also included for the following: (A) a device for producing a video flow representing a mosaic generated from a set of original video flow (B) an information medium such as CD-ROM, hard disk, floppy disk, or electrical or optical signal, readable by a computer system comprises instruction permitting to implement mosaic video flow producing method (C) a computer program stored in an information medium comprises instructions permitting to implement the mosaic video flow producing method.
