Advanced Modulations and 4K Ultra-HD TV @ SET 2013 Broadcast and Cable

Advanced Modulations and 4K Ultra-HD TV @ SET 2013 Broadcast and Cable

Newtec news Tuesday 13 August 2013

4K Ultra High Definition (UHDTV) will definitely be one of the most discussed topics during this year’s edition of SET 2013 Broadcast & Cable.  As satellite is a broadcast medium by nature this will surely impact our industry.

Hosting all those 4K transmissions on satellite will be a challenge and automatically a number of questions pop up: Will new technologies and standards emerge offering us a higher efficiency?, how to implement 4K in broadcast contribution and distribution over satellite?, Is how to roll-out 4K in co-existence with HDTV and SD? Is there a smooth transition path to 4K? …

These are all relevant questions we asked ourselves and which we would love to discuss with you.

It Starts With a Trial!

Already several transmissions of 4K UHDTV over satellite took place and more will follow. Newtec has been actively involved in the majority of these demonstrations, to name some:

Live transmissions in 4K may occur faster than you may expect. Wouldn’t you like to see the 2014 World Cup in UHDTV?

Find out more at our booth (#B14) and we’ll explain you in detail how we’ve supported these demonstrations.

Advanced Modulations and RF Carrier ID

In satellite transmission the user pays for the space segment. The larger the space segment, the higher the cost. Satellite users are looking for solutions which provide the highest efficiency to reduce operational costs. It is also required to have the highest service availability.

4K or UHDTV as most call it, will require more bandwidth. Even with the upcoming HEVC compression standard, bandwidth demands are expected to increase.

Over the last year DVB has been very active defining new standards offering higher efficiencies (DVB-S2 Extensions) and allowing for carrier identifications (the new DVB-CID standard) to identify interfering transmissions.  Earlier this year DVB defined a standard for RF Carrier ID (ETSI TS 103 129 v1.1.1) and at present DVB is finalizing the definition of a new standard which will enhance the efficiency of the current DVB-S2 standard.

21 August Bart van Utterbeeck, General Manager of Newtec in South America, will present in a tutorial session at the ‘SET 2013 Congress’, the following topics:

Efficiency beyond DVB-S2

  • How to compare two different modulation technologies?
  • What is the meaning of  “modulation constraint”?
  • Higher order modulation schemes: 32APSK, 64APSK and beyond
  • Clean Channel Technology® and Carrier Spacing
  • Linear versus Non-Linear channel
  • Some practical examples:

- Use of 16APSK with Clean Channel Technology in DSNG contribution

- Reference cases of UHDTV contribution and distribution over satellite

RF Carrier ID

  • What is RF Carrier ID?
  • Industry support and implementation of RF Carrier ID

Looks like it will be an interesting show and we look forward to meet you there in person, both at our booth (#B14) or during the tutorial session.
