Coding Technologies and DTS have announced the immediate availability of the aacPlus/DTS audio compression solution, integrated in the STi71xx MPEG-4 decoder family of chips from STMicroelectronics for MPEG-4 HDTV consumer set-top-boxes. The single-chip solution operates an aacPlus multichannel decoder from Coding Technologies with a high quality DTS encoder, which outputs digital multi-channel audio directly in the DTS surround sound format to an AV home receiver.
The aacPlus/DTS audio compression solution allows digital broadcasters to deliver multi-channel audio in the highly efficient aacPlus format while simultaneously reaching the complete audience of 60 million DTS enabled surround sound systems already installed in homes.
aacPlus is regarded as the most efficient audio compression technology available today, as proven in many third parties tests conducted by independent organisations such as the EBU (European Broadcasting Union), MPEG (Moving Pictures Expert Group), or the IRT (Institut fur Rundfunktechnik).
Specifically for 5.1 surround, aacPlus provides at 160Kbit/s the same audio quality as competing technologies at 384Kbit/s.
The incorporated DTS transcoding operates at its highest quality bit rate of 1.5Mbit/s, not only enabling backwards compatibility to the installed base of home theatre set-ups but also to guarantee best listening experience of 5.1 multichannel surround sound.
With the availability of the STi71xx single chip solution, ST offers a convenient and cost efficient way for manufacturers to integrate aacPlus/DTS audio compression into their HDTV set-top-box products.

This in turn enables broadcasters to deploy aacPlus for multichannel audio, using the available transmission spectrum most efficiently throughout the whole signal chain from contribution, through distribution, to emission.
'The aacPlus/DTS transcoding method creates a real choice for multi-channel audio in digital broadcasting and demonstrate the 71xx family's flexibility and capability to cope with state of the art evolution of codecs', says Laurent Remont, Chief System Architect Home Video Division, STMicroelectronics.
'aacPlus has already a strong standing in digital broadcasting as DTS has in home theatre surround sound'.
'Combining these two techniques into a new entity is not only a compelling idea but also a logical step as its performance offers benefits across the chain for device manufacturers, broadcasters, platform providers and network operators alike'.
'Today, new services demand more than ever for innovative technical solutions', states Ted Laverty, director of global broadcast licensing, DTS.
'Lowest transmission costs, full access to the growing multichannel audience from day one, and DVD-quality audio are of utmost importance'.
'That was our goal when entering into the co-operation with Coding Technologies at last year's IBC, and only one year later, we're there'.
'We're proud of having such an important player as ST in our camp, with a strong reputation for innovative products'.
Adds Stefan Meltzer, Vice President Broadcasting/Consumer Electronics, Coding Technologies: 'ST has once again demonstrated its enormous flexibility by responding to the demands of the market so quickly'.
'aacPlus offers the most efficient way to introduce multichannel audio to broadcasting, which is a must-have for HDTV services'.
'The availability of the STi71xx as a key platform for our modern surround sound technology will clearly spur this trend'.
