A concept for source decoding in digital video broadcast applications
Joris van den Hurk, Peter Frencken · 2005
ICs for a full-featured "plug and play" MPEG2 digital video broadcast (DVB) source decoder for implementation in DVB integrated receiver decoders (IRDs) are presented. The ICs perform descrambling, demultiplexing, audio decompression, video decompression, composite video encoding as well as external interfacing. In addition to microcontroller-related memory, the source decoder requires only 16 Mbits of decompression memory. Only a minimum of peripheral hardware is required. Driver software support requirements are moderate. A microcontroller is only required to handle conditional access information, program specific information, and audio/video synchronization.
