Explanation

Mpeg Feeder And Video Feeder (MFD and VFD)

-Mpeg Feeder is a data path of VSB or QAM decoded signal. These signals go to the Minititan of BCM3550.-In the minititan block do processing the MPEG and video.

VDEC ( Video Display Decoder)

-This block has several detailed block. It can handle the input composite signal for example, Y/C separation,color decoding, auto gain control, etc.

Digital Input

-Digital input can handle digital video signal. In our system through this path, component,RGB PC, HDMI/DVI signalsare decoded. So this path is very important block in our system.
