Note 1: See Section 4.21 for Audio Error Status.

Note 2: In 3G Level B mode, separate Video Error Mask registers exist for Link A and Link

4.18.1 TRS Error Detection

TRS error flags are generated by the GS3471 under the following two conditions:

1. A phase shift in received TRS timing is observed.

2. The received TRS Hamming codes are incorrect

Both SAV and EAV TRS words are checked for timing and data integrity errors.

For HD mode, only the Y channel TRS codes are checked for errors.

For 3G mode Level A signals, only Data Stream 1 TRS codes are checked for errors. For

3G Level B signals, the Y channel TRS codes of both Link A and Link B are checked for

errors.

Both 8-bit and 10-bit TRS code words are checked for errors.
