AC3 5.1 audio downmixed to Dolby Pro Logic II

This was a mixture of Rec.709 1080i50 footage filmed around Sydney and Melbourne in 2001, and some older Canadian 1080i60 footage with motion-compensated framerate conversion. This was the second version of the loop, where a marketing package was included from "The Quality Shows" promotion, and the logo was updated to spell out "HIGH DEFINITION" not "HDTV". The stream contains a small number of momentary breaks in the DVB-T transmission, from poor reception of the broadcast. The stream ends with a cut to the simulcast/triplecast of the live broadcast on the Nine network — being studio based, it was one of the few shows in native HD on 12 February 2004.

Please leave a comment if you want to guess why the Canadian footage was inlaid as 1920x1035i into a 1440x1088 stream — who created the 1035i (analogue HD) footage? The 1440 was due to the triplecasting reducing the available bitrate, and the 1088 was due to early generation MPEG-2 encoders requiring modulo 64 (though not as early as the WIN HD ones that had 4 separate encoding zones, and could not allocate variable bitrate demand across the entire frame).
