FCC
Lifts Freeze on Filing of DTV Maximization Applications and Petitions
for Digital Channel Substitutions
On
May 30, 2008 the FCC released a Public Notice (DA 08-1213) announcing
that it will lift effective immediately, the freeze on the filing
of maximization applications and petitions for rulemaking to allow
requests for channel substitutions to the DTV Table of Allotments.
The Commission encourages stations to file these applications
promptly.
The FCC imposed
a freeze in August of 2004, on requests from full power and Class
A television stations to maximize facilities or change DTV channels.
The freeze provided a stable database during the channel election
process and the initial processing of applications for post-transition
digital facilities. The Public Notice stated that the FCC had
anticipated being able to lift the freeze in mid-August, 2008,
but, as a result of successful expedited processing efforts, the
FCC says it has completed its review of, and has granted all post-transition
construction permit applications (except for those requiring international
coordination or additional information from the applicant). Therefore
the FCC can lift the freeze on the filing of maximization applications
twelve weeks earlier than originally anticipated.
In addition
to lifting the freeze, the Commission reminded stations which
have filed for further reconsideration in the DTV Table of Allotments
Proceeding that they may now file maximization applications, if
needed to obtain authorization for the facilities they sought
in their reconsideration in Docket 87-268. The Public Notice stated
that stations should take this opportunity to file maximization
applications, rather than rely on their pending petitions for
reconsideration to preserve their ability to maximize in the future.
The Notice
also stated that the FCC will not, at this time, accept petitions
for allotment of DTV channels for new stations, or for changes
in community of license. The Commission did however, emphasize
that the mere filing and pendency of a maximization application
or petition for digital channel substitution will not excuse a
station's compliance with the construction deadlines for full,
authorized DTV facilities established in the Third DTV Periodic
Report and Order.
Finally the
Public Notice clarified the exact time of that post-transition
construction permits will expire. The Commission's automated filing
system (CDBS) has issued post-transition DTV construction permits
with an expiration of February 17, 2009 at 3:00 a.m. local time.
The expiration of all of these permits is now extended to February
17, 2009, 11:59:59 p.m. local time.

Notice is available on the FCC's Web at: http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-08-1213A1.pdf.

FCC
clarifies the Third Report and Order on the DTV Transition
The new ATSC standards A/53:2007 (all parts) and A/65C
with Amendment 1 were adopted into the FCC rules by the Third
Periodic Order1 for the DTV transition and their provisions became
effective May 29, 2008.
These standards
have a few technical changes from the previous versions in the
rules and the original language adopting PSIP provisions was troublesome
and felt to be impractical across all broadcast operations. NAB
(and others) asked for clarification and a postponement of the
implementation date. The postponement was not granted, but an
important clarification was issued, which addressed the key operational
issue.
The original
Order asserted that broadcasters must accurately fill the contents
of the fields and the descriptors of each event descriptor loop
with the known information about each event at the time the event
is created and shall update each field if more accurate information
becomes available. The FCC has effectively clarified the meaning
of 'known' and 'becomes available' by stating that: "While
we encourage stations to update the EIT as rapidly as possible
when overages or other circumstances result in changes to scheduled
programs, our rules and policies do not require that updates be
accomplished in real-time. The rule adopted in the Third DTV Periodic
incorporates by reference the ATSC PSIP Standard A/65C which does
not require real-time updates." The order also noted that
"Because real-time updates are not required, there is no
need to address the alternative request in MSTV/NAB's petition
for reconsideration for an extension of the effective date for
compliance with the rule."
Therefore,
as of May 29th, the equipment that creates the PSIP data is required
to be able to send the actual event titles when the inputs to
the PSIP equipment contain the titles. The time to get updated
titles with the associated metadata (descriptors containing the
content advisories, closed captioning information, content identifier,
audio characteristics and such) to the PSIP generator is an operational
matter. There are no fixed time intervals from the time a change
happens until the new data is transmitted from the DTV station
in the 8VSB signal. The particularly difficult operational situation
to manage is overruns and emergency replacements, which can create
discrepancies between what was planned (in the EITs) and what
is actually happening. Depending on what degree of automation/system
interconnectivity exists, the amount of time to get matched up
again is not predictable, and getting the data right is generally
of secondary importance compared to keeping the programming on
the air. However, if this data about the program is not correct,
consumers may complain to the station or the FCC that they were
misled. Management of such situations to prevent the number of
complaints becoming large enough to motivate FCC readdressing
this regulation is the responsibility of each station.
Another change
was made which alters and improves how audio characteristics are
signaled. In summary:
1) The AC-3_audio_stream_descriptor
was modified to create a new method for signaling the language
of an audio track exists.
2) This (AC-3) descriptor is now required to be in the EIT when
a program has audio. This descriptor can enable consumers to
see what language the program will contain by sending codes
for the language (or languages) of the audio(s), if the consumers
have receivers supporting the new method (which ATSC standardized
back in 2005) and may then select a program based on language.
3) The old method of signaling language for the current program
(in the PMT) is now optional but strongly recommended. This
may be of particular interest to broadcasters being carried
over cable systems with 'old' digital set top boxes, which only
can use this old method, otherwise being unable to select audio
based on language. Some old DTV sets may also rely upon this
old method.
NAB and MSTV
also sought clarification that where more than one of the Commission's
viewer notification obligations adopted in the Order is triggered,
a station may comply with the Commission's requirements through
use of a consolidated notification that includes all of the elements
required in each of the viewer notification obligations. The FCC
clarified that they "will permit use of such a consolidated
notification in circumstances in which the Commission approves
service adjustments that overlap in time. Indeed, we believe it
could be confusing for viewers to hear multiple notifications
that seem to conflict. Stations that prefer to have separate notifications
for separate service adjustments may take that approach, as well,
provided they offer clear information to viewers."
