AM62A7-Q1: MSC limitation

Biao Li
Expert 6550 points
Part Number: AM62A7-Q1


Tool/software:

Hi Expert,

There is new project need is one 8M camera and one 2M camera, the dataflow as below:

Camera(3840x2160 NV12@30fps) --> MSC(640x384 NV12@30FPS) --> Algorithm

Camera(1920x1080 NV12@30fps) --> MSC(640x384 NV12@30FPS) --> Algorithm

Camera(3840x2160 NV12@30fps) --> MSC(1920x1080 NV12@30FPS) --> Enc

customer are affrid about the MSC capability,  can AM62A MSC support this?

or customer need using pyramid mode, the dataflow just like below:

Camera(3840x2160 NV12@30fps) --> MSC(640x384 NV12@30FPS) --> Algorithm

                                                      --> MSC(1920x1080 NV12@30FPS) --> Enc

Camera(1920x1080 NV12@30fps) --> MSC(640x384 NV12@30FPS) --> Algorithm

 which solution is better? can you help give some guidance to us?

BR,

Biao

    Hi Biao,

    The MSC only scales down by up to 1/4, ie. the maximum downscaling you can do is 3840x2160 -> 960x540. You can utilize 2 MSC instances, for example:

    Camera(3840x2160 NV12@30fps) --> MSC 0 (1920x1080 NV12@30FPS) --> Enc

                                                                                                                            --> MSC 1 (640x384 NV12@30FPS) --> Algorithm

    Camera(1920x1080 NV12@30fps) --> MSC 1 (640x384 NV12@30FPS) --> Algorithm

    Regards,
