HE-AAC is the predominant audio streaming codec. All major streaming and media platforms support HE-AAC, for example Flash, Silverlight, Windows Media Player, Winamp, and iTunes. The operating systems Mac OS X and Windows come with HE-AAC as well as the mobile systems iOS, Android, Windows Phone, Symbian and BlackBerry.

Yes, the option to switch to DD format only presents itself when the selected channel is broadcasting multi-channel audio, but if there is an HE-AAC signal encoded in the broadcast the TV will decode it and pass it via optical to the receiver as DD\DTS, this is whether it's 2.0 or 5.1 (both of which I've seen)!

AAC is the good quality audio codec which gives better compression technique to save the bandwidth. Because it remove the signal components which are not required. Also it eliminate the audio signal which are repeating. MPEG-4 HE-AAC is used in streaming media, Podcasting and radio broadcasting where audio quality is the major concerned.

La codificación de audio avanzada de alta eficiencia (HE-AAC), que a menudo se denomina aacPlus, es un sistema de compresión con pérdida de audio digital. HE-AAC está optimizado para su uso con aplicaciones de transmisión de audio en las que se requieren bajas tasas de bits, como radio por Internet y servicios de transmisión de música.

HE-AAC is opdimized for lower bitrate encodes. it uses more of the bitrate in places where it need it. if you encode 400AAC with HE-AAC and check it in a spectrogram you will found out that it removes everything above 16khz~ (where it's harder to tell the difference) and uses all that bitrate for everything below that frequency.

AAC v2 is also a superset of HE-AAC, providing the highest level of flexibility for broadcasters as it contains all the technical components necessary for audio compression over a high bitrate range (see the section called Audio quality evaluation on page 7). Another important feature of the HE-AAC and HE-AAC v2 architecture is the extremely ...
