Re: Docket 060512129-6129-01
Dear Mr. Brown,
UpdateLogic is a three year old software technology company
based in
Southborough, Massachusetts.
UpdateLogic respectfully requests that NTIA require the Digital-to-Analog
"converter boxes" to be capable of receiving software
updates from an
"over-the-air" terrestrial broadcast distribution
service.
The converter boxes are a key component of the Digital-to-Analog transition,
but the proposed NTIA specifications are out of step with consumer
electronics reality. The converter boxes are essentially small
computers
which contain a set of software programs; software that has
bugs and needs
updates. From PCs to cell phones to ATMs, routine and multiple
software
upgrades have been installed to fix errors, improve quality,
and maintain
functionality. The converter box will be no different.
The impact of one or more software bugs in the converter box
could reduce
performance, freeze out some channels, or cause a complete
system crash.
The software also controls the V-chip, emergency alert system,
and closed
captioning in the box. If something goes wrong with the converter
box
software, the digital television transition and all the legislative
effort
to create it may be compromised.
Converter boxes can be enabled with the ability to receive
software updates
by way of an over-the-air download mechanism as is done in
comparable
devices in many other countries. Over-the-air downloads can
fix software
errors before consumers are even aware of them and without
any action by the
consumer. Installing an over-the-air feature in a converter
box costs
significantly less than $1 per converter box and is easy for
the
manufacturer to include in the device.
NTIA should not spend $1.5 billion on converter boxes without
including this
feature. Furthermore, because consumer equipment manufacturers
will build
the converter box to meet the narrowest interpretation of the
specification
to qualify for the coupon, the NTIA rules must mandate such
an over-the-air
update feature.
It is wholly insufficient to say the market will take care
of this issue.
Normal tradeoff calculations by manufacturers of the costs
to support a
product do not apply here. The device that qualifies for the
coupon is
heading towards being a throw away item. It need only work
long enough so
that it is not returned to the retail store within a very short
period after
purchase. Hence the less fortunate consumer, who cannot afford
a higher end
device with good product support (including over the air download
capability), will be stuck with an unsupported converter box.
NTIA must
mandate that these converter boxes contain software update
capability.
Without the mandate, the consumer will suffer and the government
which
designed, funded and sponsored the converter box will be blamed.
No one can predict what will happen with a new product and
its new software.
But there are certainly historical indications of the need
for NTIA to
require that converter boxes have the ability to receive software
updates to
correct problems. Here are a few software problems that have
already
occurred in consumer electronic devices in the US market which
very similar
to the converter box:
* In 2006, a software bug in two types of digital televisions
after
1200 hours of use suddenly prevented the devices from powering
off (unless
the consumer completely unplugged the devices). The internal "clock"
interfered with the software-controlled on-off switch.
* In 2005, a supplier of components for satellite digital television
receivers (devices which are comparable to the converter box)
accidentally
shipped a hardware and software platform to a satellite set-top
box vendor
for mass production which did not have close captioning working
at all. A
software update, delivered over-the-air via the satellite network,
was sent
out after units were sold to the consumers.
* In 2004, a supplier of components for digital TV devices
reported a
bug in their software which caused the TV to freeze if the
consumer was
watching a channel which had a program shown at 720p resolution,
then
switched to another channel with a program at 480i, then switched
back to
the 720p content.
* In 2003, one manufacturer's digital television device experienced
a
software problem with closed captioning from several different
digital
terrestrial broadcast stations. The software problem caused
the devices to
freeze.
Imagine the economic, logistical, and political nightmare
which would occur
if these converter boxes fail to operate because of a simple
software error.
What if the software bug required a total recall of the device?
The NTIA
should take steps to avoid failure of the Digital-to-Analog
transition where
feasible. Software errors are easy to fix using an over-the-air
download
system. Here are a few other potential problems related to
software
errors:
* Terrestrial over-the-air television transmissions are spotty
and
sometimes unreliable. Reception levels change constantly and
are affected
by controllable factors (station wattage, antenna size/direction,
etc.) and
uncontrollable factors (weather, interference from other sources,
etc.).
Inside the converter box is a digital tuner which is controlled
and
configured by software. Given the dynamic and different environments
which
the converter boxes will be deployed (basements, boats, dorm
rooms,
tailgates, beaches, sheds, etc.where antenna TVs are located)
it is not
possible to test all levels of broadcast strength, frequency,
and types. If
the tuner software is unable to process the content it receives,
it may
"freeze" and in doing so "freeze" the entire
device and produce a blank
screen. Imagine the frustration level of the consumer whose
analog TV was
able to receive and display the analog terrestrial broadcast
in the same
location before the government imposed this digital transition!
* To date, very few people have watched digital terrestrial
content
broadcast. The 14 million digital television devices which
exist in the US
market today are high-end, large size television sets. These
sets are
typically connected to a digital cable box or digital satellite
box and they
do not receive the digital terrestrial broadcast. Even within
this small
exposure, the industry has experienced many problems with the
digital
terrestrial broadcast. As some of the consumer market is "forced" by
the
federal government to receive its television content from a
digital
terrestrial source, more and more people will receive digital
terrestrial
signals and more problems will be exposed. Thus, issues are
likely to be
discovered as the millions of converter boxes are deployed
and used.
* The converter box is going to be sold and distributed in
massive
volume in short period of time around the analog shut off date.
Typically a
consumer electronics manufacturer realizes a software bug in
the first few
months of a product's life cycle when only a small number of
devices have
shipped. The manufacturer can address the small quantity of
sold units and
fix the others still in the warehouses without too much cost
or hassle. In
the case of the converter box, the first few months might result
in millions
of units shipped. Fixing all of these deployed units located
in consumer
homes throughout the country will have substantial costs. Using
an
automatic over-the-air update service will help to reduce costs
should this
situation occur.
* Buggy or just out-of-date software can cause many on-going
problems.
Software programs control everything inside the television
device. However,
there are specific problems a software program could cause
the converter
boxes to experience. Close captioning, emergency alert, and/or
v-chip
parental control features are all driven by software. Typically
these
features evolve and change over time.
* V-chip parental controls may have changes in ratings and
the
possible addition of the educational/informational category.
* Emergency alert messages which come through digital broadcasts
must
be decoded, unencrypted and displayed on the television set.
Digital
distribution of messages over the emergency alert system (EAS)
is still in
early stages and not really tested in mass. There is software
within the
converter box for handling the EAS data. The modernization
of the Emergency
Alerting System (now underway) will likely have changes in
the data
standards that use it, such as the OASIS Common Alerting Protocol
that has
had two versions in the last two years.
* If software inside the box does not work, or if the format
and
structure of the v-chip rating or EAS message changes (by a
standards change
such as the new OASIS Common Alerting Protocol) the EAS alert
may not be
displayed.
Governments of other countries which have started the transition
from analog
to digital terrestrial broadcasting have created the infrastructure
necessary to update the software inside the digital television
devices. In
most cases, the government assisted and encouraged the use
of over-the-air
bandwidth for delivery of software updates to the TV device.
In many cases,
the government mandated that the devices be capable of receiving
such an
update. These governments recognized the need for routine software
updates
and took action to protect the consumers and create a smooth
transition to
digital. Here are a few examples:
* In the UK, it is common to routinely deliver software updates
to
devices. The industry consortium "Digital Television Group" administers
the
Engineering Channel, which uses BBC television broadcast frequencies
to
allow manufacturers to download software updates to receivers.
See
http://griffin.dtg.org.uk/retailer/download_schedule.pl. Service
providers
such as Cabot Communications offer the technology to do so.
See
http://www.cabot.co.uk <http://www.cabot.co.uk/> .
* In Japan, a government-organized consortium delivers over-the-air
updates to digital television devices using broadcast bandwidth
from NHK.
See http://www.nhk.or.jp/strl/publica/dayori-new/en/n-0012-1e.html
and
http://www.arib.or.jp/english/index.html (the equivalent of
the US ATSC A/97
specification).
* In Germany, as part of the so-called "Berlin-Brandenburg
switch-off", a summary report concluded that the capability
of "downloading
new software through the air.is required" in all digital
terrestrial
television receivers (including the German equivalent of the
converter box).
See
http://www.digitallaw.net/switchoff/berlin_project_report.pdf#search='Digita
l%20Terrestrial%20Transmission%20Berlin%20Brandenburg'.
Two major Korean television manufacturers (LGE and Samsung)
formally asked
the Advanced Television Systems Committee (ATSC), which was
selected by the
US Government to control television standards in the United
States, to
create a standard for downloading fixes and updates to any
digital
television device. See attached letter. The letter started
the creation of
the now completed ATSC A/97 standard. See
http://www.atsc.org/standards/a97.html.
As a result, the digital television industry has the ability
to deliver
software updates to these converter boxes easily, inexpensively,
and without
the need for consumer interaction. The ATSC A/97 standard provides
the
guidelines and specifications for delivering software updates
via
"over-the-air" broadcasts (also known as "datacasting").
Technology
compatible with the ATSC A/97 standard has already been developed
and
successfully tested by our company (UpdateLogic), the Public
Broadcasting
Service (PBS) and several digital television manufacturers.
Other service
providers like UpdateLogic and/or television broadcast networks
like PBS are
able to provide similar over-the-air datacasting services based
on the open
ATSC standard.
UpdateLogic has been developing an over-the-air distribution
system in the
US for digital television sets, most of which are connected
to cable systems
or satellite systems. The same distribution system and technology
can be
used for any digital television device, allowing UpdateLogic
to offer a very
economical solution for the converter boxes. In July of 2006,
UpdateLogic
successfully completed field test trials of the "UpdateTV" technology
service at select stations within the PBS network. Major consumer
electronics manufacturers participated in the field trial including
Hitachi,
Samsung, and Sharp. The UpdateTV service will be commercially
available in
2007 and therefore ready for manufacturers of converter boxes
to use.
UpdateLogic suggests the NTIA include the following language
in the rules
specifying the characteristics of a certified converter box:
. Receives software data downloads from an over-the-air terrestrial
broadcast, compatible with the ATSC A/97 standard, which repairs,
fixes and
corrects errors or otherwise upgrades the pre-installed software.
NTIA needs to protect the consumers and the investment of
taxpayer money in
the subsidy program by requiring the converter boxes to have
the ability to
accept fixes for software problems. NTIA should require the
capability to
fix software errors remotely using an over-the-air download
service which
can be provided at a low cost and at minimal consumer inconvenience.
The
NTIA should adopt best practices from the consumer industry
and from other
countries to take precautions, especially where those precautions
are easy
and inexpensive, to make sure the converter box works.
