Anything purchased now will be MPEG4 compatible and T2 as well.

Get a Fetch TV box - MPEG-4 and 4K capable plus loads of apps and 1 TB hard drive for recording programs on free to air and other channels.

As much as Iād love to see it, Iām not holding my breath for a coordinated change by all the networks. My prediction is Nine making a change, moving to an all-MPEG4 bouquet except Channel 9 SD, and an LCN rejig similar to what WIN has (perhaps TVSNās contract isnāt the reason WIN uses 81-83 for multiās?)
| 9 | 9HD | MPEG-4 |
| 90 | 9HD | MPEG-4 |
| 91 | 9GemHD | MPEG-4 |
| 92 | 9Go! (HD?) | MPEG-4 |
| 93 | 9Life | MPEG-4 |
| 94 | 9Rush | MPEG-4 |
| 97 | Extra | MPEG-4 |
| 99 | Channel 9 (SD) | MPEG-2 |
With a bit of luck theyāll give Channel 9 SD a limited life and switch it off in 2024.

If Nine eventually remove MPEG2 9 SD, would they have enough bandwidth for HD 9Life and 9Rush, or would that stretch the bandwidth?
Canāt fit it in around Extra running informercials in 8K

90HD is currently about 4.5 vision but 9GemHD is only 2.6 - it would be higher when sport is on.
9/91 is currently running 2.2 and 9Go! is about the same. 9Gem SD is on 1.6.
So if 9 and 9Gem SD were scrapped there would just be just enough for 9Go, 9Life and 9Ruch to go HD but at fairly low bit rates compared to the main channel. There would definitely be enough for 2 extra HD channels.
(Iāll run the numbers for a better average over a few hours as it does vary a lot)

By T2 I assume you mean DVB-T2? How much more efficient is T2 than MPEG4? (Iām not all that familiar with it).
Pretty much double the bandwidth. UKās DVB-T2 muxes hold about 40Mbit/s

Yes - DVB-T2 that was used for the 4K trials - I believe it uses about 1/2 the bandwidth.

Would it be worth trialling a T2 channel perhaps? 9Go SD and 9Go HD T2?
I assume TVs within the last 7-8 years have the tuner built in?
But itās still ordinary MPEG-4 on DVB-T2. The encapsulation (MPEG-whatever) is not related to the DVB standard. They could use MPEG-2 on DVB-T2 not that thereād be any reason to

You canāt. The entire mux has to be either DVB-T or DVB-T2, with MPEG-4 services on them.

Ahh I see. So I guess itās the type of thing which would probably have to be mandated by the government, a switchover date like with the analogue switchoff?

Current 9 multiplex
| 9 and 91 | 2.33 |
| 9 HD | 3.93 |
| 92 Gem | 2.08 |
| 93 Go | 2.58 |
| 94 Life | 2.62 |
| 95 GemHD | 3.36 |
| 96 Rush | 2.85 |
| 97 Extra | 1.37 |
Proposed - remove 9 and 9Gem SD and allocate those bits to create Go, Life and Rush all in HD
If is quite feasible - the average for each of the resulting 5 HD channels would be 3.95 which is adequate.

They could launch a HEVC channel on the current mux?
9rush in HD would be good too

All of them in HD would be better. Dump Extra and 9SD and they could do it. Just.

Not sure DVB-T allows for HEVC like T2 does?

The UK has 8MHz wide TV channels whereas Australia has 7 MHz wide TV channels. So in Australia, with similar settings youād probably get closer to 35 Mbit/s, which is still an improvement over the 23MBit/s with DVB-T.
