The Battle Over TV Channel 6 and LPTVs Used for FM Radio Broadcasts

A controversy has bubbled up in connection with the FCC proceeding to set the date by which Low Power Television stations will be required to convert to digital operations.  While the analog operations of full-power TV stations were mandatorily terminated in 2009, Low Power television stations and TV translators have not yet faced any end date for their analog operations - though the FCC recently suggested that the final date for analog broadcasting by these stations be set - perhaps as soon as next year.  In comments filed in the proceeding to set the end date, the question of when to terminate analog broadcasting became tangled in another issue - whether Channel 6 LPTV stations should be allowed to continue to be used to broadcast FM programming.  NPR suggested that the practice be terminated now, while Channel 6 licensees argued that this use was perfectly permissible under FCC rules, and that it provides a public interest benefit that should be preserved.

Channel 6 is immediately adjacent to the FM band.  Analog television stations used an audio transmission standard that was very similar to that used by FM stations, and the audio from analog Channel 6 stations could be picked up by FM radio receivers. In many major television markets across the country, LPTV operators have taken their stations, optimized the audio for FM reception, and started broadcasts intended to be treated like radio stations - programming music or talk like a radio station, with the video programming being secondary to the audio output.  Some have called these "Franken FMs", and many listeners don't even realize that they are listening to a station licensed for video operation - just assuming that radio on 87.7 or 87.9 is a normal extension of the FM band.  But this proceeding to end analog television broadcasting has brought the issue to the forefront.

Why would anyone care about these stations?  Several reasons present themselves.  First, NPR has suggested that some of these stations may be creating interference to noncommercial FM stations low on the FM dial, and adjacent to these channel 6 stations.   In addition, the existence of these stations have posed issues about increasing the facilities of noncommercial stations low on the FM band.  And, finally, there have even been proposals, about which we have written before, to take television channels 5 and 6 and use them for radio.  Some of these proposals include suggestions about reserving some of the spectrum for noncommercial stations.  Obviously, the more "television" stations operating on these channels. the less likely that the channels will be reallocated to radio.

The question of whether using LPTV stations to provide an audio service is permissible centers around the interpretation of Section 73.653 of the FCC rules, which permit television stations to operate separate audio and video transmitters "used with different and unrelated program material."  While objections were raised as to whether this rule was meant to allow audio-only programming during all hours of station operations, proponents of these radio-type uses of LPTV stations claim that the rule, by its terms, does not prohibit these operations, so the FCC should not interfere. 

Where will this go?  While, when we've written about this issue in the past, we have had readers tell us that that they believe that the FCC will find a way to grandfather these radio-like broadcasts even when LPTV stations go fully digital.  Given the FCC's interest in clearing the TV band and repurposing part of it for broadband, this should be an interesting argument to watch develop.  

There were other interesting proposals made in the LPTV digital conversion proceeding, and debate about whether that transition should be mandated quickly or whether it should take place on a more gradual basis.  And there are even suggestions that LPTV itself could be used to provide a broadband service.  We hope that we have a chance to write about those issues in the coming days. 

FCC Authorizes Mobile DTV Receivers Without Analog Tuners - Further Signals of the End of Analog LPTV, and Raises Questions of Recapture of TV Spectrum for Broadband

Last week, the FCC's Media Bureau granted waivers of the requirement that television tuners be capable of receiving both analog and digital television transmissions, but only with respect to tuners meant for mobile use.  The FCC justified the waivers of the All Channel Receiver Act given the technological constraints that an analog reception chip would put on mobile receivers meant for the reception of the Mobile/Handheld Digital Television Standard (A/153) signals.  This signal is being tested now to allow television broadcasters to provide mobile programming in addition to their current over-the-air broadcast signals - a service planned for commercial roll out at the end of the year.  These waivers, granted in response to requests by Dell and LG Electronics, not only signal the seriousness with which this new service is being regarded, but also provide evidence of the coming end of analog television, now used solely by LPTV stations.   

In considering the waiver, the Commission recognized that the only television stations that would be affected by the lack of an analog tuner were LPTV stations, and no such stations opposed the waiver request.  As one of the waiver proponents noted, analog television signals were not meant for mobile reception, and thus the lack of such a receiver in a mobile device was no big loss.  Moreover, the FCC noted that the digital conversion of LPTV stations has already begun, in that it no longer accepts applications for new analog LPTV stations.  The Commission reiterated that it will soon set a date for the final conversion of the last analog LPTV stations to digital.  Thus, the failure to receive analog would be, at most, a temporary issue.

The order allows mobile receivers to leave out not only the analog tuner, but also a tuner that is capable of receiving normal over-the-air digital television pictures, as long as their is a clear disclosure to consumers that these tuners are not capable of receiving normal analog or digital television programming.  Thus, these will be dedicated devices for the new mobile television service. 

One interesting note is that the success of this service will make it more difficult for the Commission to reclaim television spectrum for broadband use.  The old VHF channels, still used by some television stations, though much less congested than in analog days, are reportedly not very good for mobile use.  Were the Commission to try to take back television spectrum for broadband use, where could they put the TV stations displaced from the reclaimed spectrum, especially if they have successful mobile operations?  Thus, the services which this ruling promotes may help to shape the debate about the broadband recapture. 

Analog Television - Not Dead Yet - Not All LPTV Stations are Digital

Reading the papers and watching the news this weekend, one would think that analog television is a relic of the past - something that we can all soon look back at fondly as a quaint childhood memory, never to be seen again.  Yet all the reports fail to mention that for populations that watch their over-the-air television from TV translators or Low Power TV stations, analog television is still very much a reality, and in some places will be for years until the FCC sets a deadline for the digital conversion of these stations. Many of these stations operate in rural areas or serve minority or other specialized audiences, perhaps explaining the lack of coverage in the mainstream media.  But, given all the publicity that has been accorded to the "completion" of the conversion, some of these populations may well have been confused by the process.  We've writtenabout this issue and how it could have created confusion in smaller markets which have service by both full-power and low power TV stations, here.

The transition of LPTV to digital raises a number of issues - including the ability of these stations to deliver radio-type programming when operating on Channel 6.  As we've written, LPTV stations on Channel 6 have been used to provide radio services, as Channel 6 is immediately adjacent to the FM band and can be picked up on most radio receivers..  However, when the ultimate transition of LPTV to digital is completed, the ability of these stations to provide a radio-type service will probably disappear, as the audio system used by digital television will not be picked up by analog radio receivers. 

As we recently wrote, the FCC has just announced a window during which LPTV stations can file for new digital channels that were made available by the full power conversion between now and June 30.  This is but one more step toward the day when these last analog holdouts will make their transition.  The government is also making available funds to help many of these stations make the transition (see our post here).  We will only wait for the FCC to set the date when that transition will be mandated, and analog television broadcasting will truly be a relic of the past.

UPDATE 6/18/09:  I received a message in response to this post, from someone very involved in the LPTV community, who says that engineers are working on a way to allow the analog audio signal to be embedded in the digital LPTV transmission, so that using LPTV for radio-like services may still be possible after the LPTV digital transition.  It will be interesting to hear any specifics on that proposal as they become available.
