Larry Goldberg:
Yesterday's presentation gave an opportunity to discuss television
captioning in general, and it touched a bit on digital. Today we will
focus exclusively on digital television, where it came from and where it's
going. We'll talk about the upcoming digital television transition, for
which there has been concern about how it all is supposed to work.
When captions on HDTV work, it's a wonderful, fantastic experience. The
captions are better than ever. We will talk about how we can make that
work even more frequently. Each of the panelists will have a few minutes
to present from their perspective both the industry aspects and consumer
aspects.
History of HDTV and Captioning
I'll give a quick history, just to get us up to today. Discussions
began in the early 1990s when the United States decided that we needed to
develop a new television system to replace our old analog system. A number
of proponent systems were put forward. The Federal Communications
Commission (FCC) asked the proponent systems to get together and pick the
best features of all of those systems. They put together what was called
the "grand alliance," which eventually became the standard for digital
television when the FCC adopted it as a requirement in 1996.
Many things were still left open at that time, but the alliance finally
came together with a very robust, excellent and flexible digital
television system for the United States.
Also in 1990 te Television Decoder Circuitry Act was passed. It
required caption decoders to be built into every analog television set.
And with a great deal of skill, the following line was added to the act:
"As new video technology is developed, the commission shall take such
action as the commission determines appropriate to ensure that closed
captioning service continues to be available to consumers." I believe
Karen Strauss either takes credit or gives credit to others for having
inserted that line into the law, which protects us with today's HDTV and
what it needs to do for supporting captioning.
In 1996, the Telecommunications Act was rewritten and in that bill was
the requirement for broadcast, cable and satellite television to be
captioned. This included digital television captioning. And in the year
2000, the FCC issued their report and order on digital television closed
captioning, with the requirements for both the hardware and service.
The July 2000 report and order said that by July 1, 2002, digital
television (DTV) sets and tuners and set top boxes must support standard,
large and small caption sizes, user selectable or producer selectable,
eight fonts, eight captions and background colors, captioning edging,
which also included character background translucency, six standard
captioning services.
These applied to all DTV receivers, if they were in the old fashioned 4
by 3 aspect ratio, 13 inches, diagonal and larger. If they are in the
elongated 16 by 9 format, then those sets, 7.8 inches vertical and larger
also had to have the built-in caption decoder circuitry, as well as all
DTV tuners with or without displays. We knew at that time much of the
technology would be separated, and sometimes the display would be
separated from its tuner.
And finally, there was a requirement that programming produced for
these digital television sets after July 1, 2002 would have to be closed
captioned.
The Results
That resulted in caption windows and sizes, colors and fonts [Displays
crisp looking fonts, translucent background, proportional fonts]. These
are much better looking captions than we have in the analog world.
[Displays a screen shot] This is from one TV set's onscreen menu, where
you can select from all of the parameters, or default, so you can reset it
back to the standard look. That is what is now required in all of this new
digital television equipment.
