TMS320DM368: Linings around the object in Video

Part Number: TMS320DM368

Hello, 

We have DM368 based  customized board. We have interfaced 24bit RGB LCD with DM368 and resolution is 800x480. Our LCD is running on 27MHZ and refresh rate is 55Hz.  LCD is working but distortion around the objects apperars.

We are using dvsdk 04_02_00_06 and kernel version is 2.6.32.


Our data flow is like this.
capture(720x576:UYVY)---------------->Resizer(736x576:YUV420PSEMI)-------------------------------------->Resizer(800x480:YUV420PSEMI)---------------------------------->Display(24bit RGB LCD:800x480)

Use Case 1:
At the time of live video or playback video, distortion appear arround the objects when display device is LCD.


When we display some graphics, then no distotion occurs.

Use Case 2:
If our display device is CVBS Out, then video is clear.

We are attaching input image and output image (LCD Image) and video which shows the problem.

Please look into and provide some solutions

Thanks & Regards
