'If uncompressed, an MPEG-2 video broadcast needs around 8 Mb/s, and in fast-moving sequences (such as a sports broadcast) it can demand peak bandwidth of around 15 Mb/s. Compression will deal with the bandwidth hunger, but that's more applicable to pre-recorded content than for live streams.'

Err, what? MPEG-2 _is_ a compressed system. Potentially _massively_ compressed. At present ABC1 is going to air terrestrially at approx 3Mbit/sec average (peak is higher of course). Given that an uncompressed SD YUV stream is around 280Mbit/sec, that's about a 100:1 ratio.

Perhaps you mean if the video is more compressed, say using MPEG-4 AVC?
