    DVB-T2 Trial in the USA

    The US Federal Communications Commission (FCC) has given the green light for the first-ever DVB-T2 trial in the USA.

    A license for a 6-month trial was granted to Baltimore-based WNUV-TV. The trial aims to provide a test bed for a more efficient OFDM based delivery standard, such as DVB-T2, and will have an impact on how digital terrestrial TV will be delivered using current and future standards in the US and beyond.
    Other broadcasters, suppliers and industry trade associations will also take part in the tests and the trial results will be shared with NAB, ATSC and others.
    The objective is to test the impact of how OFDM can make TV content more accesible to viewers by:

    1. Identifying representative link budgets for a variety of use cases in different locations within the service area;
    2. Determining how a scalable Quality of Service offering combined with flexible transmission attributes might facilitate the simultaneous provision of television broadcast to multiple viewing devices;
    3. Providing data that may support the development of coverage and service contour matching techniques;
    4. Confirming the ability of OFDM to support Ultra High-Definition television within the existing 6 MHz channel assignments;
    5. Exploring technological capabilities that could lead to the ability to evolve a future broadcast standard;

    The US broadcasts its terrestrial signals under the ATSC format, but the Federal Communications Commission (FCC) has just approved a 6-month trial of Europe’s OFDM-based DVB-T2 standard. The trial will take place shortly on a Baltimore station between the hours of 1am-5am.

    The rationale behind the trial is to use it as a test-bed for ‘next generation’ TV transmissions, which might even lead to nation-wide adoption leading to Ultra-HDTV.
    The 6 month trial licence was granted on February 15th to WNUV-TV in Baltimore, owned by Cunningham Broadcasting which on a normal day is affiliated to the CW network. Cunningham say that other broadcasters, suppliers and industry trade associations will take part in the tests. WNUV will, more or less, supply its normal roster of overnight programme direct to cable operators, leaving the over-the-air signal free for the trials.
    WNUV will then supply the results of the trials to NAB and others. It can, should it wish, seek to extend the trial.
    Former FCC commissioner Richard Wiley, who supervised the adoption of ATSC, speaking at an event last Friday, said he thought a new transmission standard accommodating ultra-HDTV and multiplatform delivery was in broadcasting’s future, but says it might take up to a decade because it is not backward compatible-it will require new TV sets.
    The first objectives of the trial are:
    - Identify representative link budgets for a variety of use cases in different locations within the service area
    - Determine how a scalable Quality of Service offering combined with flexible transmission attributes might facilitate the simultaneous provision of television broadcast to multiple viewing devices
    - Provide data that may support the development of coverage and service contour matching techniques
    - Confirm the ability of OFDM to support Ultra High-Definition television within the existing 6 MHz channel assignments
    - Explore technological capabilities that could lead to the ability to evolve a future broadcast standard
    Or straight from the horses mouth here:

    According to the experimental license grant, there will be a small number of daytime trial hours aswell.

    I doubt the FCC is moving towards DVB (at this stage anyway), but probably more likely using the results to better design the next iteration of ATSC.

    Anyone in Baltimore going to import a 6Mhz capable DVB-T2 box and tune in? (FWIW it would probably be easier to get a TV card for PC)

    Any thoughts on the trial?

    All good so far....

    USA tests DVB-T2
    By Chris Forrester

    A giant 1,223 ft high terrestrial tower, standing on Television Hill in Maryland and which covers the Baltimore-Washington DC region switched to Europe’s DVB-T2 (OFDM) digital TV transmission for a few hours in the early hours of March 27. The 800+ kW tower beamed out using an experimental licence issued by the FCC to Sinclair Broadcasting’s WNUV-TV station as part of a study to gauge whether DVB-T2 could be the USA’s ‘next generation’ transmission system (the so-called ATSC v3.0).Part of that participation may intersect needs to test and evaluate various systems and technologies,” Sinclair VP Advanced Technology Mark Aitken wrote to ATSC’s president, Mark Richer. “I would like to extend to ATSC that Sinclair will make every reasonable effort to provide support for its ongoing 3.0 activities by providing for the use and access to the WNUV facility to support experimental needs…. We are committed to no specific standard or provider.”
    The results were excellent, reported Aitken. “The configuration we operated gave us additional data band-width yielding 24.92 Mbps [some] 30 per cent more than standard ATSC—with a [carrier-to-noise ratio] of 15.1 dB—same as ATSC—with an [modulation error ratio] of 33.5 dB, and shoulders well within specs at -53dB or better at the output of the system,” Aitken said. “We were running and receiving HD programming. For the record, it was received over-the-air with a USB T2 receiver,” reported trade magazine TV Technology.

    Yeah, it seems to me like this is a precursor to a spectrum grab. The FCC wants more efficient modulation so they can pack and cram more channels into less space so they can free up more spectrum to sell. I don't think this is about 4K, although that's what they'll try to sell it as.
