In a specific embodiment of the present invention, a system and method is
disclosed having a plurality of modes for providing and/or receiving
compressed video data at a frame buffer memory. The modes include
providing compressed video data directly from a system host system or
through a direct memory access controller; or indirectly from a system
host through a demultiplexer portion using one or more registers to
receive and handle a transport stream. Another mode of operation includes
receiving a transport stream containing compressed video data from a head
end system. The compressed video data is subsequently processed through a
demultiplexer portion.
