On the opening day of the 114th AES Convention in Amsterdam, surround audio technology leader DTS is hosting a presentation addressing the latest developments in high-quality multi-channel audio for digital broadcast.
Those attending the presentation will be treated to the first-ever public broadcast of DTS 96/24 Digital Surround, via Swedish Radio’s 1.5 Mbps DVB multi-channel satellite transmission. The digital audio service has been operating in test mode since February, and has been enhanced to handle the high-resolution DTS signal for the AES demonstration.
The presentation at 12 noon tomorrow (Mar.22) will be introduced by leading sound recording engineer and producer Stuart Bruce, who will also deliver this year’s keynote address at the AES Convention.
Mr. Bruce is a leading proponent of multi-channel audio production, with almost 20-years’ experience in stereo recording. His credits include work with artists such as Stevie Wonder, Roy Orbison, Frankie Goes To Hollywood, Barry White and Bob Marley. He is based in his own production suite at Peter Gabriel’s Real World Studios.
The presentation will address all aspects of implementing high-quality multi-channel sound in the broadcast chain, including production, contribution and transmission issues.
Other participants in the presentation will include will Bosse Ternstrom and Lars Mossberg, senior engineers from Swedish Radio who have first-hand experience transmitting the first publicly available 96 KHz, 24-bit quality 5.1 broadcast service.
Swedish Radio’s DVB multi-channel test transmission service uses the DTS Coherent Acoustics compression/decompression algorithm. The free-to-air broadcast service is being transmitted across Europe using the Nordic and European beams of the Nordic Satellite AB (NSAB) Sirius 2 satellite (5 degrees East), on 12.245.34 MHz Vertical and 12.379.60 MHz Horizontal, respectively.
The test also includes terrestrial transmissions over DVB-T supplied by Teracom. SR’s transmission follows the inclusion by the DVB of DTS Digital Surround as part of its Digital Television specification.
