But why would Dish not use it on their newest MPEG-4 receivers? Their HD is or soon will be exclusively MPEG-4, and their Eastern Arc service is MPEG-4 only, so that would seem to be the perfect time to go with it.Scott in FL said:DVB-S2 is something you don't hear much about in this forum, and I applaud DirecTV for taking the leap and adopting it (the "other" company isn't using it). The article mentioned a 30% performance improvement over DVB-S, and this is true. What it means to us is more HD channels and less rain fade at Ka band. DVB-S2 allows MPEG-4 compression for HD and pilots to recover the signal during high noise conditions (rain fade).
So far DirecTV is using DVB-S2 for some of the locals. The problem with DVB-S2 is it's not compatible with the older DVB-S receivers, so they have to replace all of the older receivers before they can implement DVB-S2 across the board. This is the main reason Dish has so far chosen to not use DVB-S2.
Don't know. When I was at the NAB show in April I walked over to the Echostar booth and asked if Dish had any plans to implement DVB-S2. The person I spoke to said no, because it was too expensive to change out the existing receivers.tkrandall said:But why would Dish not use it on their newest MPEG-4 receivers?
Thanks Curtis0620!S2 Licensing Formally Launches DVB-S2 Patent Licensing Campaign
Monday August 25, 7:00 am ET
DVB-S2 Patent License Offered Under Essential DVB-S2 Patents Owned by DTVG Licensing, Inc. and RAI (Radiotelevisione Italiana); European Space Agency (ESA) Expected to Join Initiative Soon
EL SEGUNDO, Calif.--(BUSINESS WIRE)--S2 Licensing announced today the launch of a licensing campaign under the combined patent rights in DVB S2 standardized technology held by DTVG Licensing, Inc., a wholly owned subsidiary of The DIRECTV Group, Inc. and the owner by assignment of DIRECTV's essential DVB-S2 patents, and RAI. ESA is in the late stages of agreeing to the initiative and is expected to contribute its DVB-S2 patent rights to those of DIRECTV and RAI, at no additional cost to licensees, later in 2008.
DVB-S2 (Digital Video Broadcasting - Satellite, 2nd Generation) is the second generation DVB system for broadband satellite communications, covering digital TV and HDTV broadcasting, interactive services, and professional links by satellite. DVB-S2 enables delivery of a significantly higher data rate (e.g. 30%) in a given transponder bandwidth than the previous DVB-S standard.
For the convenience of adopters, the license under the combined portfolios (currently representing over twenty patent families) is now available to all parties practicing or planning to practice the DVB-S2 standard, and provides favorable terms to speed adoption of the DVB-S2 standard. For consumer applications, such as satellite television set-top box receivers, a license under the combined portfolios is available for a one-time royalty of US$0.50 for each encoder or decoder present in a product for quantities exceeding 500,000 over the term of the license, and US$1.00 per encoder or decoder in lower quantities. Terms for other applications, such as digital satellite news gathering, data trunking, and up-link station modulation, are offered at reasonable and non-discriminatory terms, available upon request.
Attractive financial incentives are available for parties who enter into the license agreement prior to December 31, 2008. Parties interested in more information or in securing a license are invited to contact John T. Whelan, Esq., CLP ([email protected]), or visit our website at www.s2licensing.com. Appointments with interested parties are also being scheduled in association with IBC2008 (Amsterdam, 12-15 September 2008). Please contact us to schedule a meeting.

Well said and described.Ken S said:It means they've taken a bunch of related technologies from several companies and bundled them into an easy to "eat" license ("Happy Meal"). They are hoping others that now know the licenses are available and at what the costs are will adopt the technology and pay the fees. Without offers like this its risky for a company to adopt a given technology without first entering extensive license negotiations with multiple companies.
The companies that created this initiative have figured out some split of the license fees.
It also tends to serve as notice to those that may be using the technology without a license that DTV holds those patents and what they would claim as damages.
You say that like its a bad thing.......OTA-HD, unless taken directly from the station via fiber which they are not doing at very many places, will be better than DirecTV if received by a good antenna. I am not trying to starting a debate, just stating something that as a local TV engineer makes me upset.tkrandall said:I had moments of rain rade on both SD and HD local channel feeds last night during the Olympic volleyball and closing ceremony, storms in the metro Atlanta area had me reverting to OTA at times.

No, not bad at all. Reverting was a bad choice of words.tvjay said:You say that like its a bad thing.......OTA-HD, unless taken directly from the station via fiber which they are not doing at very many places, will be better than DirecTV if received by a good antenna.

Scott and/or others,Scott in FL said:DVB-S2 is something you don't hear much about ... DVB-S2 allows MPEG-4 compression for HD and pilots to recover the signal during high noise conditions (rain fade).
Pilots, or more correctly pilot symbols, consist of additional information which the receiver uses to help lock onto the carrier. That's a very simplified description.dduitsman said:Scott and/or others,
What are pilots in this context?
No, nothing to do with FEC. Just to do with helping the demod lock. 73, K7KQbobnielsen said:Possibly forward error correction?
