HDC Surround is a new 5.1 channel audio solution for HD Radio. Built on top of the HDC codec already used by HD Radio, HDC Surround will enable stations to efficiently upgrade their HD Radio broadcasts to 5.1 channel surround sound while maintaining audio quality and compatibility for stereo-only receivers. Built by Coding Technologies, the brains behind the superior performance of the HDC codec already in use by HD Radio, HDC Surround adds true 5.1 channel capability to HDC.

By building on HDC, HDC Surround provides a unique solution for backward compatible 5.1 surround sound over HD Radio.

This feature allows stations to upgrade their broadcasts to HDC Surround without negatively impacting their core stereo signal.

With the HDC Surround system, stations and receivers only need a single codec to accomplish both stereo and 5.1 channel broadcasts over HD Radio.

Existing receivers will receive the broadcast as stereo and HDC Surround enabled receivers will receive the same broadcast as true 5.1 channel surround.

"Matrix and watermark systems only provide a pseudo-surround experience which is not true to the original 5.1 channel mix", said David Frerichs, VP and US General Manager at Coding Technologies.

"HDC Surround is a true 5.1 channel encoding system that preserves the mix and provides the maximum consumer experience for surround sound over HD Radio".

"HDC Surround is designed to transmit 5.1 channel surround sound and still be compatible with today's stereo receivers", said Greg Ogonowski, VP of Product Development at Orban.

"We are working with Coding Technologies to also ensure that HDC Surround can be deployed within a modern digital radio station without a complete overhaul of the existing stereo infrastructure".
