Grass Valley Group Works With Dolby Labs To Incorporate Dolby E Into Profile XP Media Platform—Server Platform First to Support Audio Leader's Multi-Channel Format—The Profile XP Media Platform is a portal for rapid access, management, and distribution of video, audio, and data assets that supports most compression formats and both standard- and high-definition signals. Dolby E is designed to ease the transition from two-channel to multi-channel audio, enabling the distribution of up to eight channels of high-quality audio, as well as Dolby Digital metadata, via a single AES/EBU pair, thus enabling stereo-capable devices such as routing switchers, digital video tape recorders, digital audio tape decks, or video servers to handle up to eight channels of audio. This capability provides enough tracks for a 5.1 channel sound plus a stereo mix to be routed and stored together on any of these devices. In these applications the Profile XP Media Platform is used with Dolby's DP571 encoders and DP572 decoders. Dolby E is coming into common use in the production community as a solution to extend the flexibility of digital routing and storage equipment as more producers seek to produce for the new 5.1-channel audio DTV standards. Its integration in Profile XP Media Platform includes the ability to store the compressed audio streams, to detect the number of channels in the stream, and to drive audio metering by reading metadata continued in the Dolby E data stream. The Profile XP Media Platform is also compatible with Dolby Digital which is used in DTV, DVD authoring, digital broadcast satellite (DBS), and digital cable systems and is used where the Profile server is sourcing programming for final emission via an uplink to the home. "As industry-leading audio experts, we wanted to work with industry-leading video experts," said Tom Daily, marketing manager for Dolby Labs. "The flexibility of the Profile XP Media Platform and its widespread use among broadcasters made the Grass Valley Group a perfect fit." "Dolby is the brand name for quality audio for television, multimedia, music, and the movies, while Profile is the standard for rapid access, management, and distribution of video, audio, and data," said Tim Thorsteinson, president and chief operating officer of the Grass Valley Group. "Now broadcasters and emerging digicasters will be able to fully leverage these two powerful products to deliver 'being there' experiences to their viewers."
