Circuit Operating Descriptions
er filtering function as well as signal amplification.
When the output mode is 576i/480i, U704 receive Y 8 bits, Cb 8 bits, Cr 8 bit data from U1, and change them to Y
8 bits and C 8 bit forms. Inputted signals are converted to Y, Pb, Pr analog signal, and are displayed finally
through VIC3 similarly. One of these (1080i/720p/576p/480p or 576i/480i) is selected by control signal from U1.
In case of the output mode is Video, signals are passed through similar path with Component 576i/480i mode,
and VIC2 amplify the signal instead of VIC3.
13-2-2 DVD Playback
Signals from loader are inputted to U20 which is a DVD A/V decoder. U20 decodes MPEG video data and change
the data format to ITU-R656 format.
Output signal from U20 is inputted by U1, and remainder signal processing is equal with BD's occasion.
