European Broadcasters Choose Coding Technologies And DTS Compression Technologies To Deliver Enhanced Audio Experience

MPEG-4 aacPlus selected for satellite and terrestrial transmission paths

April 17, 2007

Only one year after introducing the MPEG-4 aacPlus/DTS audio transcoding for digital surround sound TV broadcasting, DTS® Inc. (NASDAQ: DTSI) and Coding Technologies today announced the operational phase of their combined compression solution at the NAB (National Association of Broadcasters) Convention, in Las Vegas. Coding Technologies’ aacPlus audio codec is currently being deployed for digital satellite and terrestrial broadcasting by HDTV broadcaster Euro1080 and in Norway’s MPEG-4 DVB-T platform. Already earlier this year, major chip set manufacturers such as Broadcom, STMicroelectronics and Conexant announced that they intend to support single chip solutions for set-top boxes with aacPlus/DTS audio transcoding, enabling backwards compatibility to the world’s installed base of home theater systems. 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. Until now, the major barrier to broadcasters implementing the latest advanced, high efficiency multi-channel MPEG-4 audio codecs for HD (High Definition) and SD (Standard Definition) TV broadcasts has been the lack of ability for consumers to decode surround sound in the home. Working with Coding Technologies in Europe, DTS has enabled the ‘transcoding’ of the company’s advanced MPEG-4 aacPlus audio codec to DTS Digital Surround in the set-top box. Capable of improving the efficiency and quality of MPEG-4 based multi-channel audio, Coding Technologies’ aacPlus audio format employs a number of advanced open standard compression techniques which release significant bandwidth and reduce transmission costs for broadcasters. The technology will allow Norway’s DVB-T and Euro1080’s DVB-S2 platforms to transmit a greater range of programming in 5.1-channel audio quality as part of their migration to second generation MPEG-4 broadcast technology. Stefan Meltzer, Coding Technologies’ Vice President of Business Development, said, “The aacPlus/DTS advantage presents broadcasters with the dual benefit of higher quality at lower cost and greater compression efficiency. We are able to offer a real alternative to the current multi-channel audio compression technique for broadcasting and believe that this format offers today’s broadcasters the increased flexibility that they need for their individual audio requirements.” Coding Technologies’ codec has the support of component manufacturers across the broadcast chain, including set-top box vendors, chip manufacturers and encoder vendors. Broadcaster’s concerns are mitigated by the capabilities of aacPlus in dialogue normalization, dynamic range control and downmix to stereo as standard, which delivers improved quality without any need for the viewer to update the home cinema set-up. “As multi-channel audio becomes an increasingly important consideration for television viewers, more broadcasters are looking to our aacPlus/DTS solution as an efficient way to streamline transmission and cut costs while delivering the end-user experience that viewers demand,” commented Brian Towne, Senior Vice President & General Manager, Consumer Division, DTS. “We look forward to working with other digital broadcasters to enhance their audio offering.” aacPlus can be used in standard or high definition deployments. Backwards compatibility ensures that audiences across the viewing spectrum can benefit from it. Capable of integrating with legacy deployments in the combination with DTS, aacPlus is also versatile enough to offer its high quality audio improvements through existing A/V receivers. 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. Founded in 1997 in Stockholm, the company later merged with a spin-off of the renowned Fraunhofer Institute in Germany, the inventor of MP3. Coding Technologies’ customers include America Online, EMP, iBiquity Digital, KDDI, O2, Nokia, Orange, RealNetworks, SK Telecom, Sprint, T-Mobile, Thomson, Texas Instruments, Vodafone, and XM Satellite Radio.
