Las Vegas (April 8, 2008)--Surround pioneer Tomlinson Holman and broadcast processing guru Robert Orban will be among the stellar group of presenters April 16th at the HDTV Audio/Surround Broadcast Conference, the 5th annual event, gathering broadcast audio professionals to discuss the technical issues, challenges and potential of the looming conversion to ATSC television broadcasting. This year's event is co-sponsored by Pro Sound News and the NAB, and is an official part of the NAB Convention's technical program.

The full-day HDTV Audio Conference will kick off at 9:10AM with "Coffee with Orban, and at 9:15AM, Robert Orban will premiere a newly developed software model of the 1981 Jones & Torick CBS Loudness Meter on a rogue's gallery of loud commercials and program elements and will demonstrate how the new third-generation version of the CBS Loudness Controller, the Orban/CRL 8585 Digital Loudness Controller, knocks them down to size. He will compare the Jones & Torick meter with the ITU BS.1770 meter on this material.

At 3:30PM, Tomlinson Holman will address the question, "Why 5.1?" While 5.1 has been widely embraced as the preferred release format for high quality HDTV sports and entertainment programming, the broadcast industry lags behind Hollywood in accepting 5.1 as the default format for DTV audio. Holman will take the audience back a step to review the historical background and highlights the fundamental advantages of the 5.1 format for television sound. He will focus on the importance of a center-channel anchored sound field in maximizing intelligibility and providing a consistent viewer experience for all types of program content and will explain how downward compatibility can be exploited to standardize production formats.

Robert Orban first began selling broadcast audio processing equipment in 1967 while still in graduate school, founding Orban Electronics the following year. Orban holds 24 patents for processing devices and is widely heralded for his design work, including studio oriented mic-pres, parametric EQs and de-essers, alongside stereo synthesis, dynamics and equalization products for the broadcast market--most notably the Optimod line of devices. Today, he continues his design work under the Orban name, now a brand of parent company Circuit Research Labs.

Tomlinson Holman is Professor of Film Sound at the University of Southern California School of Cinema-Television and a Principal Investigator in the Integrated Media Systems Center at the university. IMSC is the Engineering Research Center for multi-media of the National Science Foundation. He was the founding editor of Surround Professional magazine, and author of the books Sound for Film and Television and 5.1 Surround Sound Up and Running, both published by Focal Press. Holman was heavily influential in the penetration of multichannel audio into theater, and later into broadcast, including conceiving and advocating the use of the ".1" LFE channel. During a 15 year tenure at Lucasfilm, he developed the original THX sound system and THX audio standards. He is a member and honoree of numerous audio, acoustics and broadcast professional societies, and is the founder and chief scientist for TMH Labs. Holman holds 7 U.S. and corresponding foreign patents totaling 23, and they have been licensed to over 45 companies.
