DTS® And Coding Technologies Bring MPEG-4 Multi-Channel Audio For HDTV Into The Home At CES

Companies Demonstrate New Set-Top Box Technology that Delivers Latest High Quality aacPlus Surround Sound for HDTV to Consumers’ Home Theater Equipment

January 12, 2007

DTS, Inc. (NASDAQ: DTSI) and Coding Technologies today 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, January 8-12, 2007, in Las Vegas. The companies will hold demonstrations throughout the show at the DTS booth #1 21544, South Hall, Las Vegas Convention Center. 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 movies, more sports, more documentaries and more dramas in 5.1-channels than ever before. 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 significant 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. “Euro1080 has been the leading technical innovator in implementing European HD broadcast services. We have always been ahead of the rest of the industry, and first in the world to broadcast using the MPEG-4 standard,” said Jacques Schepers, Technical Director at Euro1080. “Now we are adopting MPEG-4 compression across all of our channels, and we intend to incorporate the advantages inherent in the DTS/aacPlus broadcast solution in our service plan, going forward into 2007.” 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. About Euro1080 Euro1080 plays a pioneering role in the field of HDTV in Europe and began transmitting on 1st January 2004. For a long time, Euro1080’s HD1 was the first and the only TV station to transmit in HD in Europe. In 2005, the Belgium-based high definition media company launched two additional HDTV stations: HD2 and HD5. HD2 (the “focussed” channel) does not only broadcast exclusive concerts, sports and other special events to cinemas, theatres and households, but is also very well suited for B2B purposes via satellite. HD5 is a demo and instruction channel. HD2 and HD5 are timesharing on one frequency. When HD2 is active, HD5 is not and vice versa. In 2006, Euro1080 started with EXQI, the HD culture channels. www.euro1080.tv About Coding Technologies Coding Technologies provides the best audio compression for mobile, broadcasting, and Internet. SBR™ (Spectral Band Replication) from Coding Technologies is a backward and forward compatible method to enhance the efficiency of any audio codec; putting the "PRO" in mp3PRO and the "Plus" in aacPlus. Parametric Stereo from Coding Technologies and Philips again significantly increases the efficiency of audio codecs for stereo signals at low bit rates. Products from Coding Technologies are fundamental enablers of open standards such as 3GPP, 3GPP2, MPEG, DVB, Digital Radio Mondiale, HD Radio, and the DVD Forum. Coding Technologies is a privately held company with offices in Sweden, Germany, China and the USA.
