DTS Partners With Coding Technologies And Linear Acoustic For Advanced Surround Sound Solution For HDTV

MPEG-4 aacPlus/DTS Audio Transcoding System and Linear Acoustic Contribution Chain Implementation of DTS Coherent Acoustics Provide Broadcasters with Highly Advanced Solutions for Discrete Multi-Channel Sound

October 4, 2006

DTS, Inc. (NASDAQ:DTSI) and its technology partners – Coding Technologies and Linear Acoustic – presented an advanced, high quality, high efficiency, end-to-end solution for multi-channel audio for HDTV broadcast at this year’s IBC, held at the RAI Amsterdam Convention Centre, in mid-September. Designed specifically to meet the challenges faced by broadcasters in production, contribution and emission of multi-channel audio for HD, the solution provides previously unattainable efficiencies in the delivery of high quality surround sound broadcast to consumers. It also provides major improvements and workflow efficiencies in the transport of multi-channel audio and associated metadata throughout the production chain. The DTS/Coding Technologies aacPlus/Coherent Acoustics transcoding scheme enables the transmission of aacPlus-encoded 5.1-channel audio at a rate of 160 kbps with the same audio quality as 384 kbps Dolby® Digital transmissions(a). The aacPlus signal is transcoded to a 1.5 Mbps DTS Coherent Acoustics signal in the consumer set-top box. In this way broadcasters adopting aacPlus have immediate access to a consumer install base of over 50 million DTS-enabled systems worldwide. Set-top-boxes featuring aacPlus/DTS transcoding are already in development using single chip decoders integrating the aacPlus/DTS transcode, which are available from a number of IC manufacturers. At the opposite end of the signal chain, DTS and Linear Acoustic have jointly developed a series of hardware tools that provide enhanced performance for contribution, distribution and emission workflows of multi-channel audio. These new units are based around an implementation of the DTS Coherent Acoustics superior compression algorithm and, as embodied in the Linear Acoustic StreamStacker-HD™ series of products, the new format is known as e2 (e-squared). e2 provides a best-in-class compressed audio transport mechanism that addresses all of the current problems of channel errors, asynchronous switching, elimination of pops, clicks, or noise bursts, and unrecoverable metadata errors (even with corrupted data streams). The Coherent Acoustics-based e2 compression format is fully compatible with existing AES/EBU and Dolby®-E infrastructures. The format fully supports all legacy workflows, including Dolby-E metadata, as well as handling Advanced Audio Metadata™. In this way e2 supports everything current, as well as provides the necessary upgrade path for future HD production workflows. Together, these DTS-partnered technologies provide a highly advanced end-to-end solution for HDTV multi-channel audio based on open standards, and a solution that offers major advantages over current technology and practice within the DVB standards. “The advent of HDTV has raised the bar throughout broadcast operations – not just in terms of image quality, but also high resolution multi-channel audio,” commented DTS Director of Global Broadcast Licensing, Ted Laverty. “Working with Linear Acoustic and Coding Technologies, DTS presents a revolutionary new broadcast audio system which enables the production and transmission of surround sound in ways that enhance workflow efficiency within broadcast operations, and provides the consumer with a high quality viewing experience.” (a) Results proven in third party tests conducted by various independent organizations, including the EBU (European Broadcast Union), MPEG (Moving Pictures Expert Group), and IRT (Institut für Rundfunktechnik). 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. 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.
