First DVD Quality Surround Sound Radio Transmission with DTS Print E-mail
Monday, 07 April 2003

Swedish Radio (SR) has announced that it will start Digital Video Broadcasting (DVB) multi-channel test transmissions from the Sirius 2 satellite, using DTS’ Coherent Acoustics compression/decompression algorithm.

The 24-hour, free-to-air broadcast service will be transmitted across Europe using both 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 period will also include terrestrial transmissions over DVB-T supplied by Teracom.

“We want to use this opportunity to test what we call High Definition Radio,” says Bosse Ternstrom, SR Senior Sound Engineer/Producer. “The acceptance of 5.1 from the consumer market, along with great sound quality possibilities, now and in the near future, has encouraged us even more.” The test began on February 7, 2003 with a live broadcast covering the PopStad festival in Vaxjo. The test period will end at the end of April 2003. It includes a wide variety of SR´s programming, including contemporary, classical and jazz music, along with comedy and drama. It will also feature remixes in multi-channel from the extensive tape and record archives of SR. Commercially available titles will also be part of the transmissions.

In order to receive the multi-channel signal, listeners will require a satellite dish able to receive the Sirius 2 transmission and a DTS-enabled set top box decoder, such as those already being manufactured by KATHREIN-Werke KG. The STB is connected via the digital output to an AV receiver with DTS decoder, in the same manner as a DVD player. In conjunction with the project, Tandberg Television is supplying the first MPEG2 encoders to support the DTS algorithm.

The Nordic beam will continue through the end of the summer and the European beam will end at the end of this month. Swedish Radio will be assessing next steps after the test is complete.
