Jim DeFilippis, Fox Television, at the ATSC seminar Nov. 4 ?ATSC hosted a seminar in Washington Nov. 4 on the issue, drawing more than 80 people including some of the nation’s top authorities in television audio. ?

?In 2006, a technical and standards group (TSG) was established to begin work on these issues. After two years of industry-wide work and involvement, the TSG has developed a comprehensive document, “Recommended Practice ATSC A/85—Techniques for Establishing and Maintaining Audio Loudness for Digital Television.” The balloting for acceptance of the document closed moments before midnight on Nov. 4.?

“We are so close,” said ATSC president Mark Richer.?

?David Donovan, president of MSTV, was on hand to comment on the relation of the TSG’s work with the CALM (Commercial Advertisement Loudness Mitigation) bill to curb television loudness complaints introduced in the U.S. House of Representatives earlier this year by Rep. Anna Eschoo (D. Calif.). ? 

?“We would have been in much worse shape if the ATSC hadn’t started work on this a few years ago,” said Donovan, explaining that Eschoo’s initiative was basically directed at loudness of commercials delivered by analog television FM audio technology. He noted that ATSC forces had made the bill’s proponents aware of the A/85 work underway and this had made for a better understand of the industry’s own efforts in controlling audio problems. ? 

?“The bill [by itself] would have undone two years worth of ATSC work,” Donovan said. “We think that the bill now is far better than what was originally introduced.”? 

?Donovan’s comments on possible legislation to tackle TV audio complaints were echoed by Richer. ? 

?“This industry needs to take care of its own problems,” he said. ? 

?The symposium featured presentations from those working in television audio, a panel discussion and a tutorial on metadata as related to digital television audio.?

Loudness in DTV will also be one of the subjects investigated ay Broadcast Synposium East, Dec. 2 in Washington, part of Government Video Expo.

?Presenters and panelists at the ATSC included Pat Waddell, Harmonic; Steve Lyman, Dolby Laboratories, Jim Starzynski, NBC Universal; Greg Coppa, CBS Television; Tim Carroll, Linear Acoustic; Sean Richardson, Starz, HBO; Jim Kutzner, PBS; and Jim DeFilippis, Fox Television.?
