Coding Technologies and Orban debuted HDC Surround, a 5.1 channel audio solution for HD RadioTM. Built on top of the HDC codec already used by HD RadioTM, HDC Surround will enable stations to efficiently upgrade their HD RadioTM broadcasts to 5.1 channel surround sound while maintaining audio quality and compatibility for stereo-only receivers.
Built by Coding Technologies, HDC Surround adds true 5.1 channel capability to HDC. By building on HDC, HDC Surround provides a unique solution for backwards-compatible 5.1 surround sound over HD RadioTM. 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 RadioTM. Existing receivers will receive the broadcast as stereo and HDC Surround enabled receivers will receive the same broadcast as true 5.1 channel surround.
