We have other issues with other stations - audio out of sync (way out of sync at times), distortion, and other channels that will freeze/drop frames as well.
I think the digital change-over here in the US was part of the problem. Apparently not everyone was ready to stream the data reliably. |
Same here with Audio too - sync seems to be a triumph of hope over expectation a lot of the time, with up to 160ms delays needing to be added on some days, yet the next it is down to zero again. Audio dropouts are distressingly common too - one of the times you will really notice dropouts is when recording an "HD" channel to the internal HDD and trying to view a different channel - tips it right over the edge a lot of the time.
OT but relevant.
Recently, our BBC dropped it's HD bitrate from 16Mb/s down to 9Mb/s.
Not surprisingly, people noticed. However the BBC head of HD was on record claiming that there is no evidence that bitrate has any effect on picture quality!
Also, has anyone else noticed that Sky are running a campaign at the moment trying to say that telephone handsets will spoil the picture?
Couldn't possibly be the pitifully low bitrate, could it! Perish the thought.
