Other Parts Discussed in Thread: OMAP3530, TVP5146

Hi,

Did somebody managed to use the omap3530 's ISP  MEMORY OFFSET REGISTER (CCDC SDOFST to deinterlace an interlaced 2-field input image please?

Please feel free to ask me any clarification if needed.

Thank you

Regards

    Yes, I have been using ISP CCDC for interlaced interface from quite some time. All PSP releases were supporting BT656 interface with TVP5146 video decoder populated in Mistral OMAP3EVM.

    Do you have any specific question here? Let me provide you the value required for BT656 (interlaced) format 0x249.

    Thanks,

    Hi Vaibhav,


    Refering to the ISP TRM, here is the configuration to write to the CCDC/Line-Output Control register for frame format conversion. I'm not just sure is this is enough, or if there are other parameters to change, to be compliant with this new configuration.

    If not, I should be able to get (with yavta application) a full 2field, right ? Please let me know if I'm wrong.

    CCDC_SDOFST[13:12] = 00b, +1 line for FID = 1 line

    CCDC_SDOFST[11:9] = CCDC_SDOFST[8:6] = CCDC_SDOFST[5:3] =CCDC_SDOFST[2:0] = 001b, +2 lines

    Thanks
