Method and system for transmitting multiple wide-area surveillance area-of-interest video codestreams

摘要

A method and system of transmitting a plurality of wide-area surveillance area-of-interest video codestreams is described, First and second video codestreams are generated from a plurality of large format images that are captured sequentially in time. The first video codestream has a first plurality of areas-of-interest selected from the plurality of large format images and the second video codestream has a second plurality of areas-of-interest from the same plurality of large format images. The first video codestream is generated at a first frame rate and the second video codestream is generated at a second frame rate and the first and second video codestreams are combined to obtain a combined video codestream at third frame rate. The combined video codestream is then transmitted through a link to a demultiplexer that regenerates the first and second video codestreams.
