This may not relate to the USA but a couple of years back I had an interesting chat with a BBC engineer at an NPL Time and Frequency gathering at Teddington. His comment was along the lines of....."....well there is as you realise not need to sync lines and frames nationally now because all the network content travels digitally even though we have only just started a phased change-over. The frames and line syncs broadcast will be probably derived from a "good clock" but it will not be a single traceable unit as it was. There is no telling how good the clock is, though it will probably be better than absolutely necesary.
