SMPTE UHD-SDI v1.0 (Rev 5) - An erroneous TRS pattern is generated when 128 channel audio is enabled

描述

When I embed 128 audio channels in the UHD-SDI TX side, an incorrect TRS pattern is detected. 

What can cause the problem?

解决方案

This is a known issue in the SMPTE UHD-SDI IP core.

It does not occur in the SMPTE UHD-SDI Transmitter Subsystem IP.

The issue occurs in sync bit insertion when 128 audio channels are enabled.

You can use the SMPTE UHD-SDI Transmitter Subsystem IP or the patch in (Xilinx Answer 71286) to work around this problem.
