Dolby E encoders And Decoders Ship Dolby E And Latest Innovations In Multichannel Audio Technology Showcased At AES

Dolby Laboratories, the world leader in multichannel sound technology, has announced its Dolby E encoder and decoder have begun shipping this month. One of the latest innovations in Dolby's arsenal of multichannel audio technologies, Dolby E professional audio coding allows broadcasters and producers to easily move multichannel audio through existing digital audio infrastructures prior to encoding into Dolby Digital for delivery to consumers. In addition to Dolby E demonstrations at the Audio Engineering Society (AES) convention, Dolby's showcase featured Dolby Digital encoders and decoders, and Dolby Headphone technology. ""Since its inception over 30 years ago, Dolby continues to be an audio technology innovator, constantly pushing the envelope,"" said Nancy Byers-Teague, Marketing Manager of Professional Audio Products. ""Our showcase at this year's AES demonstrates our commitment to excellence in sound and highlights the significant strides Dolby has made in the area of multichannel audio."" Dolby E: An End-To-End Solution For Broadcasters Dolby E is designed to ease the transition from two-channel to multichannel audio. The DP571 Dolby E encoder and DP572 Dolby E decoder enable producers and broadcasters to distribute up to eight channels of high-quality audio, as well as Dolby Digital metadata, via a single AES/EBU pair, two audio tracks of a digital video tape, digital audio tape, or video server. Designed to accommodate standard broadcast operations, Dolby E can tolerate without degradation ten tandem encode/decode cycles as sometimes required during the contribution, post-production, and distribution stages of a DTV program. In addition, Dolby E technology audio frame rates match video frame rates, enabling precise video picture cuts without mutes, glitches, or restrictions. Now DTV broadcasters and program producers can switch, route, and perform assemble edits directly on the digital bitstream without decoding and re-encoding. Dolby E also carries Dolby Digital metadata for final delivery to the home viewer's Dolby Digital decoder. In addition to the Dolby E technology and the DP571 and DP572, Dolby will demonstrate Dolby Digital for DVD, using the DP569 and DP562; Dolby Surround, featuring the new DP563 Dolby Surround Encoder (see separate release); Dolby Headphone technology; and Dolby Signal Processing (featuring the company's Model 737 Loudness Meter, Model 363 and Model DP567). About Dolby Headphone Dolby Headphone will be featured primarily in multichannel audio/video products incorporating Dolby Digital or Dolby Pro Logic Surround decoding, but will also work with two-channel stereo programs. With Dolby Headphone technology, consumers can use their favorite headphones to experience programs as if they were listening in a cinema or a fine home theater. The sophisticated Dolby Headphone technique is performed in a digital signal processor chip (DSP), which makes it easy to include in DVD Video players, upcoming DVD Audio players, set-top cable boxes, satellite receivers, digital televisions, VCRs, personal computers, video game consoles, A/V surround decoders, auto sound systems, multimedia speaker systems, and even headphone portables.
