It looks like this question has been semi answered on different posts, but can the DM368 take in 4 channels of video thru the VPFE and if so how does it mux the video? Is it line-wise or pixel-wise? I have seen a couple posts saying you need a FPGA to handle the muxing outside the DM368..Can someone answer this for sure? Could you get 4 D1s at 30 FPS coming in thru the VPFE and sent out the parallel bus?
