Imagination debuts full range of TV audio codecs

META AXD, a full audio IP platform delivering a complete multi-standard and multi-stream audio solution for System-on-Chip (SoC) designs has been extended to deliver the industry’s most comprehensive suite of standards required for decoding and encoding of audio for DTV and STB applications in all major geographies, as well as providing a powerful processor capable of supporting the most demanding applications such as Blu-ray in a single processor solution.

The suite of TV standards now supported by META AXD includes:
• AAC, HE-AAC v2, MPEG-2 BC, DTS, Dolby Digital, Dolby Digital Plus
Other standards supported by META AXD include:
• Dolby Pro-Logic II post-processing plus stereo widening, EQ, re-sampler, reverb
• Musicam, MP3, HE-AAC v2 (including DAB+ transform), Real (Cook), WMA9, Ogg Vorbis, and FLAC stereo decoders

Says Tony King-Smith, VP marketing, Imagination: META AXD is not just a next generation audio solution handling the most complex audio codecs and post-processing; it is also unique in utilizing multi-threading to deliver that performance under all System on Chip (SoC) and OS operating conditions, including demanding high system latency environments. We understand audio is not an island – it needs to be considered alongside all the other requirements in a multimedia SoC, including graphics and video. For SoCs to be competitive, off-loading key processing-intensive functions such as audio from the CPU very efficiently and at the highest possible level of abstraction is crucial if the system is to be highly responsive in all conditions.
