Hi:
I used TVP5150AMI in my DM365 Video codec board. The video capture quality is poor than my other caputer product(Capture the CVBS video with USB interface to PC) . We test the video capture for the two product as follows: In all test, I used DVD player play the DVD test signal(PAL-D).
I send test signal to TVP5150AMI on my Codec board, DM365 capture the YUV raw data, send to PC and save as Fig. 1. And then, I send test signal to USB capture card and save the YUV raw data as Fig.2
Fig.1 DM365 Capture YUV image with TVP5150AMI
fig2: USB capture YUV
It's clear that the TVP5150 capture Video resolution rate only nearly 200 to 300 line, much less than that of USB capture.
My codec board's video interface circuit same as SLEU044 and only setting the PAL video format registers in my the TVP5150 driver.
Is any advice to me how to get more resolution rate video?
