DNR, Video Encoder Blocks
The video data from the AV decoder is sent to IC251, DNR (CXD1854), subjected to video
noise reduction, and sent to the IC252 video encoder CXD1914 in the post stage. The video
data is converted to NTSC/PAL video signal (color difference signal/S-Y, S-C/composite) here.
From
Signals are output externally after passing through the 75 Sz driver.
