Free TV and Broadcast Australia to trial DVB-T2, HEVC & 4K

Recommended Posts

So the myswitch site (see below) says you're not covered by any Terrestrial TV Transmitters?

I have vast.  Cyclonic style wind off the snow and down the escarpment causes damage in these parts. 

 

What Dish size do you have installed?

Just posting these last comment to get this thread back on topic of the FTA 4K DVB-T2 & HEVC Trials.

If you haven't read these two media releases posted on the Broadcast Australia web site, then they might be of interest to you. I meant to post them earlier today when I resurrected this thread. But got busy so didn't get back here to do it.

SYDNEY, AUSTRALIA, 4 July 2018 – Broadcast Australia (a BAI Communications Company) and Free TV in partnership with ABC, SBS, have given the broadcast industry a taste of the future, transmitting Ultra High Definition 4K content live over the terrestrial platform on Friday afternoon.

The demonstration took place at the Next Generation Television Industry Showcase event and marked the first ever live transmission of 4K content over the terrestrial platform in Australia. The live 4K content broadcast was a curation of local Australian stories and sport content from national and commercial broadcasters.

The showcase was held to celebrate the successful completion of the next generation DVB-T2 trials that were conducted over the past six months. The trials were undertaken to assess the performance and potential of DVB-T2 technology as a possible replacement for the DVB-T standard for digital terrestrial television delivery.

Rohde & Schwarz facilitates Australian DVB-T2 trials

 

Rohde & Schwarz provided the entire infrastructure for the DVB-T2 trials in Australia.

 

In cooperation with Free TV, ABC and SBS, Broadcast Australia recently conducted trials of next generation broadcast technology in the Sydney area. The trial assessed the performance of next generation DVB-T2 technologies in Australia. German manufacturer Rohde & Schwarz supplied transmitters, retransmitters and test equipment for the testing phase, including an R&S TLU9 50 W transmitter, an R&S ETL TV analyzer and an R&S BTC broadcast test center.

The trial successfully assessed the performance of next generation DVB-T2 technologies in Australia. Every effort was made to ensure that the trial did not impact existing television services. DVB-T2 is being considered as a technology to replace the current DVB-T standard for television delivery in the medium term. When combined with new compression technologies, DVB-T2 will have the potential to allow 4K TV reception, which provides four times the picture quality of the current high definition standard.

DVB-T2 is essential for the distribution of broadcast content, especially for a country such as Australia, which is densely populated only on its coastline and has vast sparsely inhabited inland areas. "Terrestrial free-to-air television delivers its service to 99 percent of the population, and over 20 million Australians tune in every week," remarks Peter Lambourne, CEO of Broadcast Australia. "This trial has been an important part of ensuring that when the time is right, the terrestrial television platform will be ready for the next stage of its evolution and can deliver the best possible viewing experience."

I'm assuming they also supplied the R&S®THV9 VHF Transmitter for test transmissions on VHF at 212.500Mhz from Gore Hill.

DVB-T2, the second generation of terrestrial Transmission in DVB has been widely and successfully rolled out in other countries, together with MPEG-4 or even the latest Compression Standard HEVC.

 

Rohde & Schwarz is offering half-day DVB-T2 workshops in Sydney, that would include a DVB-T2 refresher theory,

The workshop will mainly be hands-on in DVB-T2 network simulation in a lab for Australian network configurations – from Headend to the Consumer Display. The aim is to provide a better understanding of the advantages over DVB-T use.

Also, understand the limits (Signal Contribution / Distribution, Re-transmission, SFN, Max. Bitrate) in a 7MHz Channel Bandwidth.'

 

Agenda

DVB-T2 Theory – RF Parameters
Comparison between DVB-T & DVB-T2 (MER,C/N, coverage) and to simulate the robustness of DVB-T2
T2 Gateway
Single Frequency Network in DVB-T vs DVB-T2
Wide area SFN in DVB-T2
DVB-T2 re-transmission
Capacity Load (Bitrate) using HEVC / MPEG4 Compression in DVB-T2 for different T2 Parameters

Location: Rohde & Schwarz. Unit 2, 75 Epping Road. North Ryde NSW 2113

 

 

You get the feeling that Rohde & Schwarz might have been driving the recently trial.

DVB-T2 trial happening on Gold Coast now. See:

 

https://www.txaustralia.com.au/news/505-the-future-of-tv-being-trialled-on-the-gold-coast

 

Looks like the channels being used from Mt Tamborine are 28 (529.5MHz & 43 (634.5)

Good to see they are testing DVB-T2 in other locations as well. I guess they will do the same testing they did in Sydney and finish with 4K Tests

BA have details on their Web site too. See:

Second Phase of DVB-T2 Trial commences

by Editor | Mar 11, 2019 | Media release |

 

Broadcast Australia, TX Australia and Free TV are pleased to announce that the second phase of the Queensland trial of a next generation broadcast technology, DVB-T2, is to be undertaken in Brisbane and on the Gold Coast from March to April.

The trial builds upon trials conducted in Sydney and on the Gold Coast in 2018 to assess the performance of next generation DVB-T2 technology in the Australian environment.

 

The trial will originate from the Gold Coast Translators owned and TX Australia managed transmission site located at Mount Tamborine on the Gold Coast and the TX Australia managed transmission site on Mt Coot-tha in Brisbane. The transmissions will be on Channel 28. It will be operating in a new mode of digital television technology called “extended single frequency”. Results will be analysed to determine the service threshold in the target coverage area in extended SFN (single frequency network) mode.

 

DVB-T2 is being considered as a technology which could replace the current DVB-T standard for television which has been in operation since 2001. When combined with new compression technologies, DVB-T2 will have the potential to allow 4K TV reception with four times the picture quality of the current high definition standard.

 

This trial is a collaboration between TX Australia, Broadcast Australia and Free TV Australia who would like to thank GatesAir, Rohde & Schwarz and Enensys Networks for their continued loan of equipment for the trial. It is a prime example of the innovation and first-class engineering skills within the Australian broadcast industry.

If anything is real in it, its the codec technology for the data packets, PNG and JPEG2000 along with JFIF images were made lossless compression, around 2000, 10 years later, much the same technology was being introduced in the Audio side the MP3 as a point of quality.
