Abstract:
1. A video processing system comprising: a lane alignment block configured to perform a synchronization of a video signal; an alignment detector block configured to determine whether the video signal output from the lane alignment block is misaligned and, responsive to determining that the video signal is misaligned, generate notifications indicating misalignment of the video signal; and an unlock detector block, coupled to the alignment detector block and the lane alignment block, configured to determine an amount of time that the video signal is misaligned according to the notifications from the alignment detector block; wherein the unlock detector block is configured to ignore misalignment of the video signal until the video signal is misaligned for an amount of time exceeding a threshold amount of time; and wherein responsive to determining that the video signal is misaligned for an amount of time exceeding the threshold amount of time, the unlock detector block is configured to initiate an alignment training process by the lane alignment block using training data; wherein the threshold amount of time is greater than zero.
