System and method for compressing and interleaving I scrambled digital signal streams (I 2) into a master stream and de-interleaving the master stream to provide one or more output signals streams that provide composite video and audio images as part of a program to be transported across an isochronous bus for processing by a security module and by a signal demixer. The program is returned, optionally using the same isochronous bus, to a standard digital television processing module that includes demultiplexing, decoding, storing and/or networking operations. Selective descrambling of the master stream packets is based on a signal user's access rights. Packets from two or more signal streams may be combined and/or interleaved in any ratio. |
