Coding Technologies, Philips and Linear Acoustic to Unveil MPEG Surround/PCM Multi-Channel Audio Solution for Professional Broadcasting.New Solution Enables Broadcasters to Efficiently Employ High-Quality Multi-Channel Audio for Contribution and Distribution over Existing Stereo Infrastructures VIENNA, Austria -- Coding Technologies, together with Philips Applied Technologies and Linear Acoustic, today announced the availability of a new professional broadcasting hardware/software solution based on MPEG Surround. The groundbreaking solution enables high quality multi-channel audio to be distributed over existing stereo infrastructures. Linear Acoustic will be the first company to offer the solution in their professional audio processing products. MPEG Surround, developed by Coding Technologies, Agere, Philips and Fraunhofer, was recently ratified by the ISO (1) See ISO speed. (2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI. as a codec agnostic compression technique for delivering multi-channel audio signals. MPEG Surround creates a stereo audio signal from a multi-channel audio source and a small set of parameters describing the original surround sound signal. The solution employs MPEG Surround in conjunction with a digital PCM stereo audio signal and a technique from Philips Applied Technologies known as "Buried Data technique" to embed the MPEG Surround parameters into a backwards compatible PCM stereo audio signal. An MPEG Surround decoder can then recreate the multi-channel audio based on the embedded MPEG Surround parameters. The demonstration features an upMAX-MPS professional broadcasting encoder and decoder from Linear Acoustic, which operates the MPEG Surround and Buried Data technique to transport the multi-channel audio signal in high quality over a single AES/EBU (Audio Engineering Society/European Broadcasting Union) A professional serial interface for transferring digital audio from CD and DVD players to amplifiers and TVs. AES/EBU is typically used to transmit PCM and Dolby Digital 5. stereo audio connection. The combined MPEG (Moving Pictures Experts Group) An ISO/ITU standard for compressing digital video. Pronounced "em-peg," it is the universal standard for digital terrestrial, cable and satellite TV, DVDs and digital video recorders (DVRs). Surround/PCM stereo audio combination represents the world's first solution for deploying high quality multi-channel audio for contribution and distribution in a professional broadcasting environment. It is expected that such a solution will serve remote event locations with multi-channel audio production facilities such as sports venues or concert halls. The solution enables broadcasters to transport stereo and multi-channel audio, both in the highest possible quality, over a single AES/EBU connection to the studio, without any necessary change to the existing stereo infrastructure. The audio signal is then further utilized and delivered in plain stereo or multi-channel as required. "As high definition content enters digital broadcasting, multi-channel audio is at the very heart of user's expectations," said Stefan Meltzer, vice president of Business Development at Coding Technologies. "The combination of MPEG Surround and Philips' Buried Data technique offers a highly-efficient and flexible solution to broadcasters that need to deliver stereo and multi-channel audio." "In the development of new technologies for the media world, creating high synergies has always been our goal," said Leon van de Kerkhof, program manager at Philips Applied Technologies. "As one of the developing parties of MPEG Surround, we are proud to also contribute our Buried Data technique to spur the adoption of surround sound in digital broadcasting. The early availability of the first professional encoder/decoder products is the most valid proof of concept a solution like this can achieve." "Working with Coding Technologies and Philips Applied Technologies, we are excited to offer the first practical embodiment of this excellent technology in professional broadcast hardware," said Linear Acoustic president/founder Tim Carroll. "Combined with advanced audio metadata capabilities, this new hardware will further accelerate the rapid growth of surround sound production." The new combined MPEG Surround/PCM buried data solution will be demonstrated at the AES show at the Austria Center Vienna, from May 5-8, at Coding Technologies' stand #2337.
