ABSTRACT
The idea of broadcasting data along with normal NTSC transmissions has been around for a long time. There were three main reasons it didn't work here: it did not produce acceptable data recovery in enough locations, there wasn't a single standard that could be fully developed by the industry. And the program offering was not one that either the public or advertizers were willing to support financially. The work is being done under the auspices of the National Data Broadcasting Committee (NDBC), formed jointly by the Electronic Industries Association (EIA) and the National Association of Broadcasters (NAB). The review process within the NDBC resulted in reduction of the number of systems under consideration to two – those of WavePhore and of Digideck. Approval of the WavePhore system was sought from the FCC by WavePhore in a request for declaratory ruling in December, 1993.
