    Hi,

    Unfortunately, Both DLPC2601/DLPC3438 don't support OSD. OSD is a hardware function and OSD image needs to overlay on TOP of regular image. This is not something MSP430 software can do.

    You can find some front end receivers that can do OSD or use DLPC6401 which can support OSD. All of these are hardware function on OSD, but you can program the OSD registers to control the OSD.

    Hi Jack,

    One Front end I can think of is Actions Micro’s AM8280. This is a new F/E which has OSD, MCU, but Actions Micro has other existing F/E chips which include MCU and OSD. Please check with Action Micro for detail. Note, Action Micro is a company by its own and is not a part of TI. We don't support any of Action Micro products.
