System for video transmission and processing generating a user mosaic

摘要

The TV screen mosaic square input has a coded view signal of several video inputs. From the assembly a sub sample of video signals for each video input signal is produced. A descriptor characterizing the sample is then associated with the sub sample. The assembly of sub sampled signals and descriptors is multiplexed with the video signal producing an output video signal providing a chosen screen output (502) and mosaic sub samples (505 to 507).
