8/10 bits width

Hi Hardik, Brijesh,

I would please like to have more details in this issue...

we want to encode and decode bit width larger then 8 bits per pixel (10 or 12), and according to sprugx8 it seems that such things are supported: the DVO format table shows that 10/20(double)/30(tri) bits/pixel is supported, VIP Module supports 16 YUV discrete/external sync mode, and also H264 encode/decode datasheets shows that both supports profile Level which is expected to support 8 bits/pixel or higher.

Can you please give more details where is the limitation(in software or hardware) on the following 2 distinct process:

1. capture 10 or 12 bits/pixel, and encode the frame
2. decode stream of 10 or 12 bits/pixel and send the frames to output (DVO0 or DVO1)

If it can only be done in limited way, we also would like to know how.

Thanks,

Ran

Hi Ran,

Although capture/display says that pins are 10bit per component but when it captures in memory or when it read from memory for display, it is 8bit per component.

Thank you Brijesh for the answer.

Does it mean that the 10 bits format as shown in DVO format table in sprugx8 is actually not supported ?

Thanks, Ran

8-bit to 10-bit is a interpolation, from memory its only 8-bit.

Hi Ran,

As i said, DVO supports 10 bit output, but what is read from memory is 8bit only. Display module converts from 8 to 10bits.

Thank you very much for the clarifications !
