sending a video signal from one DSP to another

Is it possible for the DM365 to receive video from another DSP(non TI) and display its output?  I want to blend this with the video coming from the DM365's video port.  The other DSP can send a serial video signal in either YUY2 or M-PEG2  format.

    DM365 supports many different video input formats as listed below

    - BT656, BT1120 YUV422 capture

    - discrete sync (Hsync, Vsync) 8bit-16-bit parallel YUV, RGB , Bayer RGB capture

     

    Other than this it has SPI interface for serial IO.

    Please refer to VPFE Guide for more details.

    From your description I couldnt make out which is the video interface format that you wish to have.

     

    regards

    i already have a cmos  camera connected to the video port and I want to get  a second video from the other DSP.  I was thinking since there is only 1 video port that I would not use the VPFE to do this but rather receive the data serially and put in on the SDRAM where the VPBE would read it witht the OSD.  The formats can be YUY2 or M-PEG2

    There is SPI interface in the DM365. Depending on the resolution and frame-rate you could use this. Refer to the DM365 datasheet for the max data rate possible on the SPI interface.
