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