Data sent from ARP is subject to decoding of the digital copy protection for preventing illegal
copy determined by DVD standards at ICS11 (CXD1904), and then sent to the AV decoder in
the post stage.
2-5. AV Decoder Block
Comp0sed of two 16M SDRAMs (IC201,202MB 81117622) and AVDEC (IC203, L64020), it
is used to decode DVD/VCD data (MPEG stream) from the decrypt.
After decoding, the video signal is letter box converted, and output together with the subpicture
and OSD signals.
The audio signal is decoded for the two channels AC3/MPEG/LPCM and output. Separately
AC3/MPEG compressed data is output as IEC958.
The CD data from ARP is bypassed inside and output from the audio output.
