Multi-channel Audio via S/PDIF (Windows CE 5.0)
The Windows CE 5.0 Networked Media Device Feature Pack includes support for WMAPro, a high quality, industry standard multi-channel digital audio format. Your device can support true multi-channel playback of this audio format by sending it over a S/PDIF cable to a home entertainment center that can split the audio back into its component audio channels.
Audio data is transmitted between components over S/PDIF with no loss in quality.
You can add this feature to your NMD using a DirectShow Media Object (DMO) wrapper, the WMAPro over S/PDIF Packetizer, that will output WMAPro data in a S/PDIF compatible format.
To enable this feature in for your device, open the Platform Builder Catalog and drag the WMAPro over S/PDIF Packetizer catalog item (found under \Graphics and Multimedia Technologies\Media\Audio Codecs and Renderers) to your configuration.
The SYSGEN variable used to enable this feature is SYSGEN_DSHOW_WMASPDTXDMO.
