Information on the Set-Top Box
Panasonic Digital Set-Top Box model TU-DST50
Current Conventional Televisions
Panasonic’s digital set-top box (STB) model TU-DST50 uses a Panasonic-developed
single chip which will allow current televisions (with AA/ inputs) to display digitally
broadcast programs. The STB, which receives only digital signals, has the ability to
convert the digital broadcast into National Television System Committee (NTSC)*
signals (480i) that a conventional television can display. The picture and sound
quality will be similar to small dish digital satellite systems today. Most conventional
televisions will not be able to display HDTV programs in their original format.
DTV-Compatible Televisions
The STB, by using component video connections, will allow DTV-compatible
televisions to produce pictures with incredible resolution. Component video consists
of three (3) primary color signals: red, green and blue that together convey all
necessary picture information. The three (3) component signals have been translated
into luminance (Y) and two color difference signals (P q , P r ), each on a separate wire.
The STB, depending on the capabilities of the DTV-compatible television, will give you
the choice of HDTV or SDTV format.
Audio/Visual Features
The STB contains two vital links to the future of TV. The optical Dolby Digital (AC-3)
output connection provides the highest quality surround sound when attached to an
external AC-3 decoder/receiver. A digital interface connection allows the STB to be
attached to a Panasonic digital VHS (D-VHS) VCR.
DTV-Compatible Monitor/Receiver Capability
HDTV-Compatible (1080i/720p)
HDTV-compatible TV models process and display high definition output from the
Panasonic STB as a 1080i or 720p format. When DTV broadcasts are available in
your viewing area, your HDTV monitor/receiver will be compatible using the STB. It
will display the 16:9 wide screen aspect ratio format.
SDTV-Compatible (480p/480i)
SDTV-compatible TV models process and display standard definition output from the
Panasonic STB as a 480p or 480i format. When DTV broadcasts are available in your
viewing area, your SDTV monitor/receiver will be compatible using the STB. It will
display the incoming SDTV format.
*NTSC is the current television system used in the U.S. It uses analog (non-digital) signals.
