Coding Technologies and DTS debut 5.1 audio solution for HD broadcasting
Coding Technologies and DTS introduced at NAB a combined aacPlus/DTS transcoding solution enabling 5.1 multichannel sound for HDTV broadcasting at a fraction of the typically required transmission bandwidth.
The new solution incorporates the MPEG-4 aacPlus audio codec with the DTS audio technology now available in more than 50 million DTS-enabled home theater receivers.
The new aacPlus/DTS technology enables broadcasters to profit from the bandwidth saving advantage of the aacPlus audio codec for over-the-air transmission and enables backwards compatibility by transcoding into DTS within the set top box.
Specifically for 5.1 surround sound, 160kb/s aacPlus provides the same audio quality as 384kb/s transmissions currently used in ATSC. This gain of efficiency frees up transmission bandwidth, allowing broadcasters to add new video channels, secondary audio or simply cut down on transmission costs.
