HD Broadcasting


#1554

Currently, all FTA HD stations are H264 1080i. In the past MPEG-2 576p, 720p and 1080i were also used.

No, that’s not what I meant.

Comes up as 401 for me.

Great recording. Would’ve been nice if they showed some footage of Sydney on the test transmission loop, but the vision of Newcastle is still good! :+1:

Let me guess what you’re using to receive these trials…a PC and some form of DVB-T2 tuner card or USB stick? :slight_smile:

I think there might still be 1080i MPEG2 HD channels in some regional/remote areas.

But yeah, all the HD channels on air in metropolitan markets + Regional NSW, ACT and Victoria are in 1080i MPEG4 these days.


#1556

You’d be correct.

You’re right. I should have clarified – all the FTA HD channels I receive (i.e. Sydney + Southern NSW) are H264 1080i (except for this new test transmission).

As of 25th April 2018, the following MPEG2 HD channels that are still operating are:

  • 7mate in regional areas of QLD, SA, WA, Darwin and Remote Central & Eastern Australia
  • 9Gem in regional areas of SA, WA and Remote Central & Eastern Australia
  • One in Darwin, Spencer Gulf/Broken Hill and Remote Central & Eastern Australia

You can add Tasmania to this too. :slight_smile:

Yes. There are 3 streams. Channel 70 should keep working but switch to the same stream as Channel 7/71. Series links would not be affected. Some people wouldn’t notice.

Similarly 73 should switch to the HD stream without missing a beat.

And since with this the SD 7Mate wouldn’t actually be being used… they can allocate that bandwidth to improving 7 and 7HD/mate.

Only problem would be the few TVs that can’t see the 7 HD. (Perhaps they could add a temporary channel 79 for SD 7mate).


#1559

That’s a pity. I just did a scan and it found channels 49-55… which have audio but no video. But sounds more like SBS? What channel numbers should it use.

Anyway, I’d rather see the networks allow Fetch to stream an HD HEVC stream over the internet.

It’s crazy that the networks haven’t been forward thinking enough to do that for HD on all their channels, and even setup tailored ads for different locations (separate Sydney into 15 regions?). (or worked with Fetch for user-customised ads etc)


#1560

Those are the new SBS radio stations. They come up in the same number range for me, knocking out the Southern Cross Nine channels that are actually supposed to be in that channel range.


#1561

I got excited seeing so many new channels I was hoping I’d have the full suite of WIN channnels on my Fetch but nope, still only WIN and One. No Eleven or WIN HD or the rest still in Tasmania.

SBS Radio channels are in but as others have said, no name and in the weird range. I think it’s actually 49, 54, 55 and 56 for mine though so I still have the Nine channels.


#1562

That LCN allocation would be at odds with FTA operational allocation to SBS of 3, 30-39 and 300-349

I was wondering if 7QLD had added a HD channel!

DVB-T2 tuner card or USB 

Can you please tell me what USB TV stick you are using thanks


#1564

I’m using an Astrometa DVB-T/DVB-T2/DVB-C/FM/DAB+/SDR USB tuner.


#1565

The radio channels come up in the range stating with 300 from Mt Coot-tha Brisbane. The radio channels from the nearby regional SBS stations are also added as being a different network stream (as happens for SBS TV).


#1566

Does SBS run different feeds in Brisbane and Regional QLD? I know that ABC has separate metro and regional TV feeds - albeit only used for the occasional Local Radio promo spot.


#1567

Since the last restack, the network ID for regional SBS has differed from the metro one. Prior to that there as a SFN in SEQ so it wasn’t possible.


#1568

I think SBS might have a different feed for local ads here in Sydney compared to what Regional NSW gets.


#1569

Yes. There’s a table and details here of the SBS feed breakup.

Tasmania and the NT use the one feed - but the other states are split regional/metro - with the ACT taking the regional NSW feed.


#1570

I can confirm this. I get both metro and regional SBS here in Sydney and the ads are different. Even the ABC, who don’t have ads seem to have a different feed for Sydney. For example, when the same promo ran for ABC NewsRadio, the Sydney feed had the AM frequency, whilst the regional feed didn’t have any frequencies listed. This was a while ago though - not sure if ABC still have a separate Sydney feed.


#1571

But is it HEVC compliant read somewhere it needs to be for it to decode video?


#1572

I second this.

Also, the last time I checked, the entire feed for SBS NSW was half a second ahead of SBS Sydney.


#1573

The codec used is irrelevant to the tuner. It’s your computer software that does the decoding (or video card, if you have GPU acceleration enabled and your GPU supports HEVC). Same applies to actual TVs – decoding of the HEVC is not related to the tuner itself.
