The DTV Express is a demonstration and laboratory vehicle that was built for
the Broadcast community to show that HDTV could be built and could be
implemented in a small space.
Willy Halla undertook this project in Jan of 98 with Harris Corporation, then
designed and completed the drawing set, supervised the building, and showed the
system in Washington, D.C. on 23rd of March 98. Much of the equipment was
proto-type and built specifically for this project. The entire system is digital
utilizing full bandwidth component signal to included 1.5 Gbs, 270 Mbs, and 48
Khz AES streams.
The system is fully functional from camera all the way through to transmitter
and receivers for both precision and consumer products. This system showed that
contrary to industry experts a comprehensive HDTV system could be built. This
included the first delivered HDTV routing switch that would handle up to 256 x
128 1.5 Gbs ports. All of the equipment utilized in the project is now
The system included a complete four (4) channel Master Control for SDV and
multi-channel, and an NTSC input into the system. This showed that Broadcasters
could enter the DTV arena at just about any level, be it NTSC, SDV, or HDTV.
The DTV Express is an industry chartered system from some 43 manufacturers and
companies. Its sole purpose is to show and teach broadcasters, government, and
media officials that HDTV is here, it is a technology for today, and to give
broadcasters a hands on approach to learning how this technology can be
implemented. The tour will go through some 40 cities and last approximately 15
months. During this time the system will be continuously updated with new
equipment as it becomes available, this will keep the system at the fore front
of the HDTV technology.
