FCC Unveils Post-Auction Repack Plans

Stations will receive confidential letters with their final channel assignments shortly after the auction’s final stage, giving all stations more time to prepare. Each station that has to move will be slotted into one of 10 transition “phases” with staggered completion dates to ease coordination issues and enable the commission to track progress.

 

The FCC today released a post-incentive auction transition proposal that includes details of how the spectrum repack — reassigning some of the TV stations that will remain on the air to new channels and coordinating hundreds of station modifications nationwide — will work. It includes a phased approach to station moves, something that many broadcasters and others have been advocating.

Known as the Transition Scheduling Plan Public Notice (TSPPN), the staff’s transition proposal includes:

  • Providing a clear schedule and early notice: Consistent with industry’s request for a clear schedule to enable resource planning, the TSPPN outlines an orderly phased transition approach and announces that TV stations will receive confidential letters with their final channel assignments shortly after the final stage rule is satisfied, giving all stations more time to prepare.
  • Using a phased approach: The proposal assigns each station into one of 10 transition “phases” with staggered completion dates to ease coordination issues and enable the commission to track progress.
  • Limiting disruption to broadcasters: The phased approach is designed to protect broadcasters from undue interference throughout the transition.
  • Prioritizing 600 MHz-band clearing: The proposal attempts to move stations residing in the new wireless band as early as possible to ensure forward auction winners have timely access to spectrum.
  • Minimizing consumer inconvenience: The proposal minimizes impact on consumers by limiting the number of times over-the-air viewers will have to “rescan” for channels.

The Challenge: Coordinating ‘Dependent’ Moves While Limiting Interference During Testing

Those stations that must move to a new channel will have to modify their existing facilities (e.g., antennas, transmission lines) to transmit on a different frequency. Then they must test their equipment. Unless a station’s new channel is “available” (i.e., free from interference caused by other stations), it will need to coordinate carefully with one or more other stations to prevent the testing from causing interference.

With hundreds of stations nationwide needing to move to new channels, there is the potential for a “traffic jam” in which a station can’t move to its new channel until a second station moves, and that station in turn must wait for a third station to move, and so on. Stations whose moves are dependent on another’s move are called “linked stations,” and these links can span dozens of stations across a large geographic area. Linked stations can switch to their new channels simultaneously to break up these congestion points, but doing so requires careful coordination.

A Phased Approach

In order to facilitate an orderly and timely transition, the staff proposes using a mathematical tool — the Phase Assignment Tool — that determines the order in which stations must transition to new channels. With hundreds of stations needing to move to new channels, there are millions of possible sequences. Therefore, consistent with overarching transition goals, the TSPPN proposes a procedure for determining the optimal sequence by assigning stations to “phases” by the end of which all stations within the phase must be off their pre-auction channels. The optimal sequence will meet a set of conditions, including:

BRAND CONNECTIONS

  • Clear 600 MHz Wireless Band As Soon As Possible: Assigning U.S. stations whose pre-auction channels are in the 600 MHz band to earlier phases would help open it up to licensees to offer new innovative services.
  • Limit TV Viewer Rescans/Preserve Regional Focus: Limiting stations in the same Designated Market Area to two phases also limits to two the number of times viewers would need to rescan for over-the-air channels. It also reflects the regional approach that stakeholders have suggested.
  • Give “Complicated” Stations More Time: Assigning the most challenging and time-consuming stations (as defined in the expert Widelity Report to later phases allows adequate time for their transitions.
  • Limit Linked Station Sets In A Phase: Limiting linked sets within a phase would limit the effect of dependencies and facilitate coordination among broadcasters.
  • Limit The Total Number of Phases to 10: Using 10 phases strikes a balance between limiting the size of linked-station sets and other goals. A greater number of phases could decrease the number of linked- station sets in each phase but makes more difficult other goals such as transitioning stations within the same DMA at the same time and avoiding the need for multiple channel rescans by viewers. Keeping the number of stations in each phase roughly equal also helps in the sharing of resources in each phase.
  • No More Than 2% Temporary Interference: Allowing temporary limited increases in interference between two stations is in accord with past transitions and would significantly reduce the number and complexity of dependencies.
  • No Temporary Channels: Using a temporary channel during the transition could reduce the size of linked- station sets but would also add costs, strain resources, and add more rescans for viewers.

A Detailed Schedule to Efficiently Allocate Resources

Once stations are assigned to phases, the Commission must determine when those stations switch to their new channels. The TSPPN proposes a second tool — the Phase Scheduling Tool — that estimates the total time necessary for stations within a phase to complete the transition, informing how the FCC will set end dates for each phase. Specifically, the tool:

  • Assigns minimum completion times for each station based on certain characteristics.
  • Allows the FCC to assess the impact of unknowns such as the order in which stations receive required resources.
  • Gives the FCC the ability to gauge the impact of resource availability and adjust accordingly.

The TSPPN proposal details the specific tasks or processes proposed to be modelled for each of the stages of the transition process, as well as the estimated time and resource availability for each task.

Putting stations into different phases with a detailed schedule will let stations, tower crews, and equipment manufacturers know when the FCC expects specific stations to complete their transition so that they can plan accordingly. It also ensures that the majority of stations will be able to test on their post-auction channel during a specified testing period without having to coordinate with neighboring stations — or those stations’ neighbors.

The commission said that comments on the plan (DA No. 16-1095; Docket No. 12-268 16-306) are due Oct. 31; reply comments are due Nov. 15.

I wish they’d do away with virtual channels and needing to scan

    And force “Brands” that have been built over Decades to be discarded? Only a Non-Broadcaster would wish that.

    No reason it has to. Spoken like someone with no clue.

It is my sincere hope that VHF stations return to DMA wide coverage with a signal that can pass through walls unlike this BS we have now…

    ATSC 1.0 will never provide that which is why Sinclair fought so hard against it last Decade.

    @Insider: Ah, your lack of reading comprehension again! Notice the poster wrote “unlike the BS we have now”… that should be a clue he/she is talking about his/her desires for what ATSC 3.0 will be…

    @RidgelineTV – Seems you have the reading comprehension issue. Nowhere in the story or the FCC issued plans, nor in @HopeUMakeIt’s comment, is there any mention of ATSC 3.0, a technology real Broadcasters, unlike yourself, hope for, but has not even been approved yet.

    Veronica Serrano Padilla says:

    October 1, 2016 at 8:11 pm

    LMAO!!! ATSC 1.0 isn’t mentioned in the story or in @HopeUMakeit’s comments either, yet you jumped to the conclusion that it was what he/she was referring to. Anyone with any reading comprehension could understand what that poster was getting at – better signal propagation with ATSC 3.0 unlike “the BS we have now” to quote @HopeUMakeit.

    Wagner Pereira says:

    Sorry to disappoint but ATSC 1.0 is the only authorized standard approved by the FCC at this time. Again, you are ASSUMING what HopeUMakeIt was infering – and you are referencing, as they call it in a court of law, facts not in evidence. Don’t try to wiggle your way out of it. You are busted.

    Nope, I’m just having fun watching you make a complete ass of yourself once again. I’ve not been “busted” at all. You just have to jump in with a smart ass comment before even thinking about what a poster is saying… and when you get caught, you generally resort to lying and slander. What a fine example of a broadcaster you are (though you’re just a beancounter)…

    Wagner Pereira says:

    October 2, 2016 at 5:23 pm

    Again, you’ve been busted by trying to explain a comment on the repack with a technology that was not part of the story or even approved yet. AGAIN the repack by itself will not help VHF Reception. Period. However ATSC 3.0 with better error correction has true potential to do that, as I have posted, unlike you, for the past 12 months.

    By the way, HopeYouMakeIt and his negative comments on Broadcasting claims to be one of the 2 Black Male Sales Reps at 1 of the 4 Major Broadcast Facilities in Houston. Let’s hope he does a better job of pitching his station with facts instead of what he posts here.

Let’s not get too far ahead, lets see if the auction found new interest, the same 63 qualified bidders are in round two, if this goes to 4 rounds there will a lot less displacement. This auction is a disaster & time water from the gitgo.

Before everyone is all jacked up about the plans, lets see where we end up !!!

As Sgt Shultz says , I see nothing etc etc

I would like to know who is going where in SW Ohio. Will I loose some or all of the sub channels? If I need to erect my 40 foot tower and HD 8200 winegard , so be it.
