DVB - use of LC-AAC and HE-AAC?

I was under the impression that Standard Definition broadcasts on DVB-T used MPEG-2 video and layer2 audio (MP2). ...and also that High Definition broadcasts on DVB-T and DVB-T2 used H.264 video with LC-AAC for the main sound with HE-AAC usually in mono at fairly low bitrate for alternate audio such as Audio Description and probably alternative languages. (It's supposed to be necessary to use codecs from the same family - AAC - as they can be interleaved in the MP4 container also used for H.264 video). There's currently a Citation Needed and I suspect it might need factual correction too. Dynamicimanyd (talk) 09:14, 6 September 2013 (UTC)[reply]
