A typical rear panel supports:
- Six channel or two channel audio outputs
- Optical and coax S/PDIF outputs.
- Composite, S-Video, and SCART outputs
Outputs provided by ZR36768 are Composite, Y/C, YUV or RGB interlaced analog video output
or component progressive analog video output (using 10 bits on-chip DACs). DVD6110 rear
panel has Composite and S-video otputs on it.
ZR36768 provides 2 to 8 channels audio output. DVD6110 has 2 channels audio output on its
rear panel. The rear panel has S/PDIF serial stream and optical output generated by the
ZR36768. CS4392 Audio DACs are used for two channel audio output with ZR36768.
