Products from Coding Technologies are omnipresent in the digital broadcasting landscape across all major systems and standards and integral parts of DVB, DMB, MediaFLO, Digital Radio Mondiale, ISDB, XM Satellite Radio, and HD Radio. Their commercial efficiency by technical superiority make them the first choice for all platforms, from satellite, to terrestrial, to cable, to IPTV.
In cooperation with DTS, Coding Technologies and the pioneer in multi-channel audio introduced the aacPlus/DTS transcoder solution, combining an aacPlus decoder and a DTS encoder to reside in a consumers set-top-box. This powerful combination allows an easy adoption of aacPlus even for surround sound broadcasting and maintains backwards compatibility to existing home A/V receivers, as well as highest audio quality.

 aacPlus
gained its first commercial success with XM
Satellite Radio. Over a given transponder bandwidth, aacPlus
allowed XM Radio to offer more channels at a higher quality than
the competing Sirius Radio system which uses the proprietary PAC
codec from Lucent.

 aacPlus
was also selected by Digital
Radio Mondiale, the only international open standard
for terrestrial digital broadcasting in the long, medium/AM und short wave bands. Already in 2004, Coding Technologies introduced the 'Digital World Traveller', world's first USB radio receiver for Digital Radio Mondiale, at the Internationale Funkausstellung in Berlin. Even before the finalization of the Digital Radio Mondiale standard in 2003, Coding Technologies developed together with its partners the DRM2010, the first consumer grade receiver.
MPEG Surround, standardized in July 2006, hit digital TV broacasting in October 2005 with a real-world DVB-T broadcast at the "Medientage München". Combined with the audio codec Layer-2, MPEG Surround delivered multi-channel 5.1 audio to capable receivers, without significantly increasing the bit rate, and without simulcasting stereo and multi-channel audio. Of course, standard DVB-T receivers continued to play back stereo as usual, from the identical bit stream!

 iBiquity
Digital, the US based developer and licensor of HD Radio technology,
has identified the enabling character of Coding Technologies'
SBR for its In-Band-On-Channel Digital Audio Broadcast system
for AM and FM in the United States. In an outstanding example
how SBR can fundamentally enhance the efficiency of any audio
codec, iBiquity adopted SBR for integration into its HDC codec
to achieve highest audio quality even at lowest bit rates.
In October 2004, Coding
Technologies and Orban debuted HDC Surround, the backwards
compatible 5.1 multichannel solution for HD Radio. Combining the powerful MPEG Surround technology with the SBR enhanced HD audio codec, HDC Surround delivers 5.1 channel surround sound
while maintaining audio quality and compatibility for stereo-only
receivers.

This
heritage has brought credibility for Coding Technologies' products in the open standards
world of digital satellite, terrestrial, cable and IPTV broadcasting.
As operators look to enhance their services with more channels
or with high-definition, the efficiency of our products gives them
more options to either consolidate audio bandwidth to make room
for more video or to layer more audio services like multi-lingual
and 5.1 surround.
Since Spectral Band Replication (SBR) is being added to the MPEG-2
standard as well, operators have the flexibility to use aacPlus
within the MPEG-2 or MPEG-4 context as desired.
