Hi.

We use RDK2.8, 8168.

What is the max FPS the SCD and OSD can support?

Thanks.

SCD: 2 fps / ch * max 16 channels @ CIF resolution .ie. 2 x 16 @ 352 x 288.

OSD: 30 fps / ch * max 32 channels @ D1/CIF resolution . i.e 30 x 32 @ D1. Note that for OSD the video frame resolution does not matter. What matters is the total area of the OSD window to be blended.We have tested with below configuration:

#define DEMO_OSD_NUM_WINDOWS (4)

#define DEMO_OSD_WIN_WIDTH (224)
#define DEMO_OSD_WIN_HEIGHT (30)

You can get performance data by running the usecase and using Vsys_printDetailedStatistics which prints info on fps for all components

Hi, Badri.

If we use 1ch 1080P60, how frames can the SCD and OSD handle?

Thanks very much.

It is not possible to do SCD for 1080P resolution.

As I mentioned OSD Mhz consumption does not depend video frame resolution so it is possible to do 1ch 1080P60 OSD.

Hi, Badri.

If we want to do some sample NSF algorithm on DSP with 1080P60.

can it achieve?

Thanks

How much Mhz does sample NSF algorithm take to process 1080P60. Based on that it can be calculated if 60 fps can be achieved.

Hi, Badri.

We use RDK2.8, 8168.

I change nsfProcCfg->staticFrameNoise[i] = 0 to nsfProcCfg->staticFrameNoise[i] = VPS_NSF_PROCESSING_CFG_DEFAULT;

the NSF has a little effect. How can I improve the image quality? what params can I setting?

what is VPS_NSF_PROCESSING_CFG_DEFAULT?

Thanks very much.

Hi Li,

Could you check if frameNoiseAutoCalcEnable flag is set to TRUE or not? If not set, could you set it to TRUE and try it out?
