8107 DVR RDK Live View Video Quality

Faizel

Hi,

We have a custom board running DVR RDK framework (GA3.0). Its been observed that video is not that sharp as compared with other commercial DVR's. Far objects are not easily distinguishable like in other DVR's. Also always the video is a dull. Means it distinguishes between the objects less pleasing as in other DVR. Also its been observed that video is more noisy. Please find the attached picture for your reference. Is there any way for improvement, below are the RDK configuration details

RDK 3.0 Running 4 channel use-case with noise filter enabled.
We don't have TVP chip. We have our own decoder. (Even with TVP in the reference board is also the same)
Decoder settings is running optimum brightness, sharpness and other values.
Active DEI mode for all the channels.
The attached picture shows live view screen

Please reply for any scope of improvement.

Regards

There are several fixes since RDK 3.0 release to select correct Scaler coefficients in both SWMS and HDVPSS driver.

Can you pls check the same on DVRRDK 4.1 and see the quality.

For NSF I will share a patch to reduce Gaussian noise. Can you confirm you have NSF enabled and you are not just using it for Chroma format conversion.

Additionally share your Vsys_printDetailedStatistics on DVRRDK 4.1 to confirm low cost scaling is not happening in SWMS.

Hi Badri,

Thank you for your reply. Yes we are using the noise filter in active mode (not for format conversion alone). If you can share the patch, that will be a great help. Is it possible for you to point out the scalar coefficients in swms and hdvpss in the code(for migration)?. Also low cost scaling is not happening in SWMS as the parameter swMsPrm[i].lineSkipMode is FALSE in all the use-cases we are running. Looking forward for your help.

Regards

The fixes for scaler coefficient is not isolated so cant be shared as patch.

It is best you migrate to DVRRDK 4.1 and check.

If that is not an option you have to completely migrate HDVPSS,SWMS link and DEI link atleast .

For NSF link attached is the patch.

Set the nsf strength to high in NSFLINk create params and ensure nsf is not in bypass.

For SWMS link the lineSkipMode is not used. Do Vsys_printDetailedStatistics and confirm LOW COST is OFF for SWMS for all the windows.
