DM8168 - Video Capture - 1920 x 1200 @ 50 fps

Hi Siddharth,

DM8168 HDVPSS (HD Video Processing Subsystem) can capture two simultaneous ( up to HD resolution, 1920x1080@60) video channels.

For more details see the below pointers:

1. DM816x datasheet

HD Video Processing Subsystem (HDVPSS)

– Two 165-MHz HD Video Capture Channels

• One 16-Bit or 24-Bit and One 16-Bit Channel

• Each Channel Splittable Into Dual 8-Bit Capture Channels

 

1 16-bit and 24-bit HD Capture Channel or 2 8-bit SD Capture Channels AND 1 16-bit HD Capture Channel or 2 8-bit SD Capture Channels

 

Two (one 16-bit, 24-bit and one 16-bit) independently configurable external video input capture ports (up to 165 MHz).

– 16-bit and 24-bit HD digital video input or dual clock independent 8-bit SD inputs on each capture port.

• VIN[0] can accept single-channel 16-bit, 24-bit (YCbCr and RGB) video or dual-channel 8-bit (YCbCr) video.

• VIN[1] can accept single-channel 16-bit (YCbCr) video or dual-channel 8-bit (YCbCr) video.

Hi Pavel

Thank you for your inputs. We did gone through the datasheets and TRMs to find out support for two 1920 x 1200 @ 50 fps video captures. From theoretical calculations, it seems that it is possible to capture two such videos. But, I posted this query here hoping that if anybody from community has already done anything similar to that, I can learn from his/her experiences and correct the architecture of our product if needed.

Yes, it is possible, we were capturing 2 channels of 1080p@60fps, so 50fps is also possible.

Hi Brijesh

Thanks for your inputs. The resolution what we are looking for is WUXGA (1920 x 1200) which is higher than 1080p HD video (1920 x 1080). Do you still believe that DM8168 should capture two such WUXGA @ 50 fps?

Siddharth
