HI , there are many daughtercards . but it is a lot of problem for us to choose the right board to meet our need. we need a HDMI CAPTRUE--> DSP algthrom -->HDMI DISPLAY. we brought a 816X/389X EVM board + 816x/389x expansion I/O daughter card(with HDMI input) , but we find that it can't run the DVRRDK demo . also the TI employee told us DVRRDK only support the VS daughter card , but it doesn't have HDMI input on the board . if we want do HDMI captrue and display , which board can meet our need and also can support the DVRRDK?
