Dolby Showcases Audio Solutions At NAB 2004

Dolby Shows Latest Audio Solutions For HDTV And DTV Terrestrial, Cable, And Satellite Services

12-Apr-04

Dolby Laboratories will showcase its latest audio solutions for HDTV and DTV terrestrial, cable, and satellite services at NAB 2004, booth #SU10443. Most notably, Dolby will debut its new LM100 Loudness Meter software remote application, introduce a new enhanced version of Dolby Digital for future broadcast systems, showcase Dolby Pro Logic II for stereo infrastructures, and demonstrate Dolby Digital 5.1-channel content for cable, satellite, and terrestrial broadcasting.The new Dolby LM100 software remote application will assist postproduction, tele-vision broadcast, cable systems, and satellite providers with advanced loudness measurement, logging features, and enhanced error reporting, enabling them to address subjective loudness issues. Applications include network QC, postproduction, DVD authoring, broadcast on-air monitoring/logging, video-on-demand (VOD) encoding, and satellite turnaround facilities.The software's features enable users to continuously log short- and long-term speech loudness values in real time, while storing the loudness history data for later analysis. In addition, the LM100 remote application also includes an event log that allows the user to continuously monitor/log several different types of input status, alarm, and error conditions. These include Dolby Digital (AC-3) cyclic redundancy code (CRC) errors, Dolby E CRC errors, loudness above and below threshold, clipping, input loss, and audio metadata.For cable head-end applications, the LM100 remote application allows users to control both the LM100-NTSC's tuner module and digital cable set-top box tuners for hands off analysis and logging for every channel on their cable system (via a third-party trans-lator, sold separately). This gives cable personnel the ability to continuously and ob-jectively evaluate how consistent loudness levels are from channel to channel within their services. The Dolby LM100 software remote application will be packaged with both the LM100-LTC and LM100-NTSC starting in the second quarter of 2004. Enhanced Dolby Digital for Future Broadcast Systems Dolby will introduce enhance-ments to the Dolby Digital format that expand the capability of the technology for future broadcast systems, while maintaining compatibility with the 37 million Dolby Digital decoders already in home receivers worldwide. Dolby Pro Logic II for Stereo Broadcasts Dolby Pro Logic II provides engrossing surround sound on any stereo-only television service, as well as on VHS tapes and top-selling video games. Hear recent Dolby Pro Logic II broadcasts, including Fox?s NASCAR broadcasts, and discover the DP563 Dolby Surround and Pro Logic II Encoder and the Dolby DP564 Multichannel Audio Decoder.Scenes from current DTV broadcasts from local networks and premium cable and satellite stations incorporating Dolby Digital 5.1 surround sound from terrestrial, cable, and satellite services will be shown in our booth theater. Enjoy the presentation and meet with Dolby experts to discuss network and affiliate station inquires, and offer assistance on each network's audio implementations. Cable and satellite attendees can also view a typical uplink configuration, and learn how easy it can be to upgrade an existing two-channel facility to include Dolby Digital 5.1-channel capability.Several high-profile events have already been broadcast with multichannel Dolby Digital in 2004. The CBS telecast of the 45th Annual Grammy Awards, ABC?s broadcast of the Academy Awards ceremony, German satellite network Sat.1?s broadcast of the FC Bayern M¸nchen versus Real Madrid soccer match, and ORF?s broadcast of the traditional New Year?s Day Concert by the Vienna Philharmonic Orchestra were all presented in Dolby Digital 5.1.Presentations by Dolby Personnel:Friday, April 16, 4:00 to 5:00 p.m. at the PBS Technology Conference, MGM Grand Hotel, breakout room #2: ìManaging Multichannel Audioî featuring panelist Mike Babbitt, Broadcast Field Service Engineer, Dolby Laboratories.Saturday, April 17, The ATSC Digital Television University, 4:45 to 5:30 p.m. Las Vegas Convention Center, N112: ìTutorial on Enhanced AC-3 Audio Codingî Craig Todd, Senior Member, Technical Staff, Dolby Laboratories.Sunday, April 18, MPEG Forum 11:20 a.m. to 12:10 p.m., Las Vegas Convention Center, S221: ìAdvanced Video and Audio Coding: A Technology Provider's Perspectiveî featuring panelist Julia Cutler, Director, Technology Strategy, Dolby Laboratories Licensing Corporation.Tuesday, April 20, Quality Control for DTV, 3:00 to 3:30 p.m. Las Vegas Convention Center, N112: ìThe History of Lip Sync, or, How Did Things Get This Bad?î Ken Hunold, Broadcast Applications Engineer, Dolby Laboratories.Tuesday, April 20, Quality Control for DTV, 4:30 to 5:00 p.m. Las Vegas Convention Center, N112: ìIntelligent Loudness Measurement and Control: What Satisfies Your Listeners and Your Set-Top Boxes?î Jeffrey Riedmiller, Broadcast Product Manager, Dolby Laboratories, and Ron Wright, Time Warner Cable.For more information about Dolby Laboratories or Dolby technologies, please visit www.dolby.com.
