Delay on WODS-HD3

The answer, from Mark M., the WBZ radio CE:
"Actually it is in the way the additional program channels are
encoded. The HD-1 program is encoded in the exciter. The HD-2 and
HD-3 are done on a computer that encodes it and delivers the complete
bit stream to the exciter which the multiplexes it onto the data stream."

Subject: Delay on WODS-HD3
I don't really know what sort of delays are considered typical for HD3
signals, but the WBZ audio on 103.3-3 seems to be about half a minute
behind the (already delayed) 1030 audio. Are they running it off a
stream or something? Surely there must be a low-delay audio path from
1170 over to Birmingham Parkway!
