DTS And Coding Technologies Bring aacPlus Sound To Home Theatres
DTS and Coding Technologies announced the live demonstration of set-top box technology that enables delivery of the latest MPEG-4 aacPlus multi-channel audio for HDTV to consumers’ existing home theater systems at the CES 2007.
With the efficiency and audio quality of the aacPlus codec, consumers can now receive much more HDTV programming in high quality surround sound, allowing broadcasters to deliver more content in 5.1-channels. They can also provide programming with multiple language surround soundtracks, as on DVD releases. They can now do so with immediate access to the entire installed base of DTS-enabled home theater systems.
Until now, the major barrier to broadcasters implementing the latest advanced, high efficiency multi-channel audio codecs for MPEG-4 based HDTV broadcasts has been the lack of any means for consumers to decode the surround sound in the home. Working with Coding Technologies in Europe, DTS has enabled the ‘transcoding’ of that company’s advanced aacPlus MPEG-4 audio codec to DTS Digital Surround in the set-top box. With a simple SPDIF connection from the set-top box, this can now be decoded in virtually all A/V receivers.
aacPlus employs a number of advanced open standard techniques developed by Coding Technologies. This creates bandwidth efficiencies and reduces transmission costs for broadcasters, allowing them to provide surround sound transmissions on a greater range of programming.
Pioneering HDTV service, Euro1080 has announced that it will implement aacPlus surround sound as part of its recent switch from MPEG-2 to higher quality MPEG-4 transmissions. Several other major broadcasters in Europe and elsewhere are also planning to implement the technology.
Incorporating the aacPlus/DTS transcode, set-top boxes from several manufacturers are scheduled to come to market imminently. IC manufacturers have been producing the required chip sets for several months now.
