Abstract

A method and system for compressed domain video mixing for spatially combining incoming video streams into an outgoing video stream. Using H.264 as an example, each incoming stream is divided into a plurality of slices, each having a plurality of header fields including a first mb in slice header field. Based on the picture format in the outgoing stream, first mb in slice for each incoming stream is modified such that the modified first mb in slice header field is indicative of location in the spatial representation of the outgoing stream at which the slice of the incoming stream is placed. H.264's slice group mechanism is used to map the spatial positions of the second and following macroblocks of the slices to the appropriate locations. If the incoming streams are previously mixed by upstream mixers, a decomposer can be used to separate these mixed streams into component streams before combining them with other incoming streams.
