DolbyÆ E Format Continues To See Wide Use In Broadcast Industry

26-Mar-01

As the broadcast industry continues its rapid adoption of 5.1-channel audio programming, DolbyÆ E technology is seeing increased use in both the post production and broadcasting realms. Big name broadcasters such as STARZ! Encore, ProSieben, Nine Network, and Network TEN have implemented Dolby E for their multichannel audio distribution needs, along with such well-known post production houses as SZM Studios GmbH, LaserPacific, Roland House, and American Production Services.Dolby E is designed to ease the transition from two-channel to multichannel audio within established DTV broadcast infrastructures, and to help program producers control how multichannel mixes will be reproduced in viewers' homes. Increasing numbers of network broadcasters have decided on Dolby E for acquisition or distribution. These include: ""As the broadcast industry moves forward with the transition to DTV, Dolby E technology becomes increasingly important because it allows broadcasters to accept and transmit multichannel audio data over media that traditionally carry an AES pair without sacrificing audio quality,"" said Tom Daily, Marketing Director, Professional Audio for Dolby Laboratories. ""Additional features that Dolby E provides, such as audio synchronous with video, allow broadcasters to smoothly edit multichannel audio without having to decode to baseband.""About Dolby EDolby E was designed to ease the transition for DTV broadcasters from two-channel to multichannel audio. Unveiled at 1999's NAB convention, the DP571 Dolby E encoder and DP572 Dolby E decoder enable broadcasters to distribute up to eight channels of high-quality audio, as well as metadata, via a single AES/EBU pair, on digital video tapes, or video servers. Dolby E-encoded audio can withstand the multiple encode/decode cycles required in TV audio production and distribution, and its frames match video frames for smooth, glitch-free edits.Audio encoded in Dolby E does not reach the consumer; it is decoded and re-encoded with Dolby Digital, the coding used for DTV broadcasts just prior to transmission.For more information about Dolby Laboratories or Dolby technologies, visit www.dolby.com.
