Re: Audio Sync problem with new 360 box
I worked for a vendor to TV companies all over the world. The technical standards people (in the UK ofcom) would be all over that. I delivered numerous updates to the video playback servers to address the precise audio video sync issues. Interestingly if the sound leads the video by up to about 10 frames most people won't notice as much; as when the sound lags the video by about 4 frames. Broadcasters have test media with a 1 frame flash and sound pulse every 10 seconds for 1 hour to verify sync and drift. I regularly watch Hallie Jackson on MSNBC now, VM channel 614. The audio on that channel is usually out of sync, In TV there's an expression It was alright leaving us and I can imagine the signal leaving NBC at 30 Rockefeller Plaza, New York is right. I Imagine the signal is delivered to Virgin by some low cost IP transport route and something in that chain causes the audio to drift in the coding/decoding processes. I'd complain but honestly life is too short. If you are interested in verifying the sync the youtube APP might be a useful place to go select one of these videos and see if the problem presents3.2KViews1like0CommentsRe: Hub status data - understanding network log messages

Andrew thank you for posting this great knowledge article, it's really helped me to drill into an issue my household has been experiencing. I have a small quibble with the term "analogue" technology. It's not an inherently analogue issue, whether the data is encoded digitally or in analogue style it's an issue with the nature of the physical media that is used for transmission and reception of data. Also a point to point passive fibre connection IIRC has 1x10^14 less errors but it too will have occasional errors when you add in repeaters, multiplexers, and concentrators.7.5KViews0likes2Comments
