UK: The two 'linked lectures' will take place in the first quarter of 2010, writes David Davies. 'Who's the Bad Guy Now? Maintaining Audio/Video Sync in Today's Broadcast Environment' will be held on Tuesday January 12, with 'Synchronising the Synchronisation Standards' to follow on Tuesday February 16.

The first session, to be presented by BBC HD head of technology Andy Quested (pictured), will address the challenges raised by the transition to digital audio processing, surround sound broadcasting and HD. Quested will also examine the audio/video synchronisation issues that the BBC HD channel has had to deal with, and outline the measures it is taking "to put audio back into its rightful place".

The second session, meanwhile, will be presided over by Broadcast Project Research's Dr. John Emmett and consider the changing world of standards and recommendations in the context of digital commodity (IT) workflows.

The lectures will begin at 7pm and take place at the Royal Academy of Engineering, 3 Carlton House Terrace, London SW1. The sessions are open to AES members and non-members.

Digital Decoded principal and AES UK Section committee member Bill Foster tells PSN-e that "the synchronisation between audio and video has always been a 'hot topic' in TV broadcasting, particularly since the advent of digital TV. With HDTV's increased resolution, any sync errors become even more obvious, further compounding the problem. Historically, the amount of processing in the video chain compared with audio has meant that it was usually the video that was out of sync with the audio; however, the move to surround sound has served to increase the amount of digital processing in the audio chain with the result that it can be the audio which creates the problem."
