Linear Acoustic Offers Seminars on HD Transition

Partnered with Omneon and Miranda to present meetings in Montreal and (December 09, 2005)

Linear Acoustic, in cooperation with Omneon Video Networks and Miranda Technologies, recently hosted the first in a series of educational seminars for broadcasters planning to make the transition from SD to HDTV broadcasting. Entitled "HDTV: Making the Transition," the first seminar was held during October in London for representatives of the British Broadcasting Corporation, BSkyB, Ascent Media Services and other organizations. It was followed last month with seminars in Montreal and Atlanta. "Many broadcasters are still confused about the choices for generating, distributing and processing high-definition material, specifically multichannel audio," considers Linear Acoustic president Tim Carroll, an acknowledged expert in surround sound technologies. "Linear Acoustic is a leader in the development of new systems for cost-effective contribution, distribution and processing of multichannel audio material."

The seminar program comprises a series of spotlight presentations on such topics as: . The Inevitability of HDTV - a look at the drivers for HD from consumers and broadcasters. . Fundamentals of Video and Audio Formats for HDTV. . HD Building Blocks - looking at distribution, routing, conversion, editing, servers and master control. . HD Case Studies - tales from the converted by senior broadcasters.

The seminars are non-promotional, and are being presented by senior engineers from Linear Acoustic, Omneon and Miranda, as well as by leading broadcasters. Technology demonstrations associated with core themes also are being offered at the end of each seminar. (A modest attendance fee is charged to cover material and refreshment costs.)

Tim Carroll's presentation, "Audio for HD: From Playout to Delivery," explored Emission Technologies - Audio from broadcaster to consumer; Contribution and Distribution Technologies - Audio to the network and local broadcaster; and Connecting it all Together - Monitoring, master control and other issues.

"The two leading multichannel audio emission technologies are AC-3 or Dolby Digital, and DTS Coherent Acoustics," Carroll acknowledges. "AC-3 carries from one to 5.1 channels of audio at data rates between 56 and 640 kbps, while DTS Coherent Acoustics - also part of the DVB standard - offers sample rates from 8 to 96 kHz, and supports up to 32 channels at 24-192 kbps/channel. Both formats are compatible with millions of consumer playback systems.
