RTOS/TDA3LA: modify mosaic configuration on a fly for PIP display

Part Number: TDA3LA

Tool/software: TI-RTOS

Dear Champs,

Is it possible to modify mosaic configuration on a fly for PIP display?

e.g. my customer is implementing 2ch output using PIP and want to make on/off PIP screen on a fly without reboot.

Could you please check if this is possible and how they can do it on VisionSDK?

They are using VisionSDK v3.6.

Thanks and Best Regards,

SI.

    Hi SI,

    Could you please help me understand the PIP that you are adding on the display? How are you adding PIP on the display? Are you using two display pipeline?

    If you are using two display pipeline, it is easier, you could use alpha blending to enable/disable PIP.. You could even change runtime position of the pip on the output..

    Hi Brijesh,

    Yes. it is two display pipeline. 2 cameras were connected to TDA3 and one camera was connected to VIP port and other one is connected to CSI2 port.

    Could you please provide more details or pseudo code how alpha blending can be used to enable/disable PIP?

    Thanks and Best Regards,

    SI.

    Hi SI,

    I dont have the exact code, we have some example in the vision sdk, in the chains_common.c file. We could set the alpha value and even enable/disable transparency. Using these features, we could enable/disable pipeline.
