Hi swami, Many thanks for the mail. Let me tell you the requirement first. We are looking into, process 4 Video/Audio Channels (capture, encode, save,stream to Net, decode/display). So one Davinci may not be sufficient.
So planning for 2 Davinci , whereas Slave (pci) Davinci chip will 1. Capture and encode 4 Videos (720x480) and 4 Audios, and encode to compression. 2. The Second (Host) Davinci will get it through PCI (as we thought as first plan) or Other Interface & 3 . The Host will save the streams, stream 4-AVs thru Network, Decode and Display 4-Ch at TV-Out with Quad mode. As we need more band width for the interface , initial thought was to use Davinci s PCI interface. have not think about USB yet. Which one does normally preferred. If it is PCI interconnection , does linux support both configuration for PCI at either side. ? If it is USB interface , does linux support this at either side ?
