  • Hi Jitendra,

    I can comment from HW side. Your HD-SDI.pdf block diagram seems to be correct for 16-bit YCbCr capture mode with embedded syncs.

    For receiving part, you can use Video Input 0 Port A:
    - VIN[0]A_CLK - Video Input 0 Port A Clock input. Input clock for 8-bit, 16-bit, or 24-bit Port A video capture.
    - VIN[0]A_D[15] to VIN[0]A_D[0] - Video Input 0 Port A Data inputs. For 16-bit capture, D[7:0] are Cb/Cr and [15:8] are Y Port A inputs.

    When you receive the video in HDVPSS through the VIN[0]A port, you can pass the video data to the HDVICP2 to apply video codec functions on that data (i.e H.264, MPEG-2, VC-1, etc). Then you can transfer the encoded data from HDVICP2 to HDVPSS VOUT port.

    From HDVPSS VOUT port you can output the data through the VOUT0 channel. You can output (i.e.) 20-bit G/Y/YC video data in embedded sync mode through below pins:
    - VOUT[0]_CLK - Video Output 0 Clock output
    - VOUT[0]_G_Y_YC[9:2] - These signals represent the 8 MSBs of G/Y/YC video data.
    - VOUT[0]_G_Y_YC[1:0] - These signals represent the 2 LSBs of G/Y/YC video data
    - VOUT[0]_B_CB_C[9:2] - These signals represent the 8 MSBs of B/CB/C video data
    - VOUT[0]_B_CB_C[1:0] - These signals represent the 2 LSBs of B/CB/C video data

    In your HD-SDI.pdf you have D[20:0] for outputm while for "20-bit G/Y/YC video data in embedded sync mode" you need D[19:0]

    Pavel

    Thank you Mr. Pavel Botev for your quick reply.

    1. GS2970 ic compatable to drive 16 bit ycbcr format?
    are from your side is there any ic which takes sdi serial input and provide 16 bit ycbcr output?
    2. GS2972 ic compatable to receive 20-bit G/Y/YC format?
    are from your side is there any ic which takes 20-bit G/Y/YC data and convert to HD-SDI output?
    3.Please provide the reference schematics to implement HD-SDI input and output interfacing with TMS320DM8168?

    I can not advice regarding GS2970 device or other SDI Deserializer. I can advice only from DM816x device side. For questions related to SDI Deserializers, you can ask post in below e2e forum:

    You can also check if below e2e threads will be in help:

    I do not have such reference design. You can check the DM816x available reference designs at below link:
