Do the AVN encoders support WSS (Wide Screen Signaling)?

No. The AVN encoders ignore WSS included on the incoming video source and do not include it automatically on the encoded output. Currently, only the AVN420 encoder allows you to manually force the output, to include the WSS, so that downstream devices can detect it. When WSS is present in the IP stream, most decoders will pass the WSS downstream on their analog or digital output signal so that the downstream display can receive it.
