Multiplex stream processing, e.g. multiplex stream decrypting

Selective content distribution, e.g. interactive television or video on demand [VOD] > Client devices specifically adapted for the reception of, or interaction with, content, e.g. STB [set-top-box]; Operations thereof > Processing of content or additional data, e.g. demultiplexing additional data from a digital video stream; Elementary client operations, e.g. monitoring of home network or synchronizing decoder's clock; Client middleware > Interfacing the downstream path of the transmission network originating from a server, e.g. retrieving encoded video stream packets from an IP network > Multiplex stream processing, e.g. multiplex stream decrypting
