Audio coding software drives TV
broadcast encoders
Broadcast encoders make use of MPEG-4 and MPEG-1 Layer-2 audio coding software.
Harmonic is using floating-point MPEG-4 high-efficiency advanced audio-coding (HE-AAC) and MPEG-1 Layer-2 audio-coding software from Fraunhofer Institute for Integrated Circuits IIS for the DiviCom Electra family of broadcast encoders The Electra 7000 HD and Electra 5400 SD H.264 encoders are being shown at the Harmonic booth (#SU9620) and the Electra 7000 will also be featured at the Fraunhofer booth (#SU6830) during the NAB2007 exhibition in Las Vegas between 16th and 19th April

Audio codecs simplify multimedia SoC design
The new MIPS Consumer Audio Platform provides easy access to a range of audio codecs developed by Fraunhofer IIS for implementation in multimedia system-on-chip applications.
Update for surround-sound software
The Fraunhofer Institute for Integrated Circuits IIS and Thomson have added two new elements to their MP3 Surround demo software.
As an option to its Electra multichannel compression platform, Harmonic has integrated the efficient and speed-optimised Fraunhofer DSP audio software in a multichannel audio card.
The Harmonic Electra encoders are used in broadcast, satellite, cable and telco IPTV headends or studios for real-time encoding of HDTV and SDTV content.
In addition to systems supporting H.264 compression, the Electra product line also includes multichannel MPEG-2 SD encoders.
Fraunhofer's HE-AAC and Layer-2 software delivers discrete multichannel audio quality at bit rates as low as 128Kbit/s.
"Our customers increasingly roll out HD and SD channels with multiple 5.1 or 7.1 audio services, and need a cost-effective, integrated solution to reduce audio bandwidth", says Arnaud Perrier, Senior Product Marketing Manager at Harmonic.
"The HE AAC codec from Fraunhofer IIS offers best-in-class quality and allowed us to rapidly incorporate this function into our market-leading line of Electra encoders".
Harald Popp, head of the Multimedia-Realtime Systems department of Fraunhofer IIS, says: "Harmonic is the industry leader for digital TV broadcast encoders, offering its customers ultra-high compression efficiency, and we are happy to see our high quality MPEG audio codecs used in their outstanding Electra family of products".
MPEG-4 HE-AAC is an efficient audio codec widely adopted in mobile multimedia, digital radio and TV broadcasting and is the de- facto standard for music download services on mobile phones.
MPEG-1 Layer-2 is a proven audio compression scheme used for years on DVD and digital TV transmissions.
