You’d be surprised. They’d come close.
Racing.com and Openshop are MPEG-4 SD and barely running above 1Mbps each.
The SBS radio channels are Layer 2 and probably minimum 192kbps, could even be 224 or 256?
They do use AAC on the Pop channels which would be less bits:
SBS Arabic24 MPEG-1 Layer 2
SBS Radio 1 MPEG-1 Layer 2
SBS Radio 2 MPEG-1 Layer 2
SBS Chill MPEG-1 Layer 2
SBS Radio 3 MPEG-1 Layer 2
SBS PopDesi AAC
SBS PopAsia AAC
I’d like to see them do more MPEG-4 exclusive services. 7Flix was launched as MPEG-4 but then quickly reverted to MPEG-2 with a fear Seven was losing audience.
Several years later though with MPEG-4 more common they should be more comfortable to run MPEG-4 only services.
Here’s what they should do.
7 SD MPEG-2
7TWO SD MPEG-2
7HD HD MPEG-4
7mate HD MPEG-4
7flix HD MPEG-4
7food SD MPEG-4
Racing SD MPEG-4
Openshop SD MPEG-4
I’d actually leave 7 and 7TWO as the only MPEG-2 services. My theory is the 7TWO audience is older and won’t like losing it if it went MPEG-4. 7Flix has a lot of movies and newer shows that would benefit being HD.
