Digital TV Technical Discussion

It used to be clear, in the old days, but by the time the mid-late 2000s came around the amount of interference on 2 was huge. That was in suburban Melbourne.

I managed to get myself a maprad.io account to kill the time in between looking after my now 2 week old son. Generated a coverage map for Sydney DTV. Receiver antenna height is 10m. Enjoy!

Thank you. First time dad at the ripe old age of 44. Not by choice. It was a long, sometimes painful and tragic journey to get to where we are now. 12 years of marriage and the final piece of the family puzzle is here. :smiling_face:

From Wednesday the 5th of February, Adelaide will get 7TWO in MPEG4 HD, and will no longer get 7 in SD, with Channel 7 and 71 becoming MPEG HD channels in addition to channel 70.

Seven is upgrading broadcast technology across Australia and on February5th 2025 there will be changes in Adelaide. These changes may require that your TV is re-tuned to reflect those updates.
Part of these changes is the removal of MPEG2 technology to be replaced with MPEG4.
MPEG4 enables broadcasters to improve the quality of the services they deliver to meet consumer demand.

The changes are as follows:

  • Channel 7 will be converting to HD (in MPEG4)
  • Channel 70 and 71 will also be HD (in MPEG4)
  • 7two will become HD in MPEG4

HD for the cricket?
Have our prayers been answered?

(please be all metro markets)

Just Adelaide at this stage

There will just be one stream that redirects to 3 LCNs. Removing the SD channel, the bits saved should mostly transfer to the 7Two HD stream.

7two is going High Definition (MPEG4) in Adelaide from 5 February 2025. 7HD is also converting to MPEG4 encoding. From then there will no longer be a standard definition simulcast of Channel 7.

This was recorded off Channel 7 Adelaide tonight during 7 News:

Adelaide is the smallest (in population) state capital, so best place to start just in case.

Isn’t 9Life already in MPEG4, just in SD?

Yes. But I may be wrong lol.

What’s with just doing Adelaide then moving to others? I’m pretty sure whenever the other channels have done a HD upgrade, they do all metro city areas at once?

Not in Melbourne at least, don’t know Adelaide for sure.

They’ve already done regional Queensland and now the ex-Prime markets. Just get on with it.

This change also means Adelaide will look identical in simulcasts and all channels having locations just like RQLD

This is what I mean. They could do Brisbane then the whole of QLD would be done. lol. I’m not sure whether they have done regional SA.

In the analog TV switch-off, Adelaide was also the first mainland state capital to switch off analogue TV. Then came the other mainland state capitals, followed lastly by Sydney and Melbourne.

Maybe the reason they stagger the switchovers is so there are less issues to deal with at any one time, but over a longer period of time. That way you could have the same people handling all the issues in all of the locations (e.g. people answering calls).

I don’t think so, especially since Regional SA is run by WIN (SE and Riverland) and SCA (Spencer Gulf, Port Lincoln, and Broken Hill)
