| Samsung Electronics America to Debut HDTV Decoder
April 6, 1998 (BOSTON) -- Samsung Electronics America Inc. will
be one of the first electronics manufacturers to provide HDTV
broadcasters with a broadcast-quality demodulator/decoder.
The new ARX-100 product supports the Advanced Television System
Committee (ATSC) professional demodulator/decoder guidelines. It
will be unveiled at the 1998 National Association of Broadcasters
(NAB) convention from April 6-9 in Las Vegas.
The ARX-100 also will be used in the DTV Express touring road
show, an 18-24 month national program initiated by Harris Corp.
and the Public Broadcasting Service (PBS) as a means of educating
broadcasters about digital television technology.
Samsung's ARX-100 is designed specifically to monitor off-air
signals. It can be used as a confidence monitor or as a link
between a measurement device and a transmitter or encoder. The
broadcast receiver will demodulate 8VSB signals and output
baseband signals in analog and transport stream formats.
The product was designed and engineered by Samsung Electronics
Co., Ltd. in conjunction with its New Jersey-based Product
Samsung Electronics America Inc. of Ridgefield Park, N.J., is the
U.S. subsidiary of Samsung Electronics Co., Ltd. of Korea.
Samsung Electronics is a US$19 billion flagship company of US$93
billion Korea-based Samsung Group. Samsung Electronics is the
fifth largest color TV manufacturer in the world.
"The broadcast demodulator/decoder utilizes Samsung's advanced
HDTV decoder technology, a subset of which will be incorporated
in our consumer HDTV products later in 1998," said Art Rancis,
vice president of Samsung's Product Innovation Lab.
The ARX-100 is packaged in a two-unit high, standard 19-in. rack
mount enclosure. The front panel display includes channel
numbers, error indicators and RF signal strength. The output of
the demodulator provides access to the transport stream, while
also providing input capability directly into the decoder
Frank Romeo, senior manager of the Product Innovation Lab, said
the company's goal in designing this product was to provide
flexibility and ease-of-use. "Features like VHF reception,
separate PCB slots for the demodulator and decoder, PC monitoring
and on-screen graphics allow broadcasters to use this product now
with analog and well into the future of the HDTV transition,"
There are three main sections in the ARX-100: the 8VSB
demodulator, MPEG2 decoder and a picture format converter, all of
which were designed by Samsung.
The 8VSB demodulator is tunable over all television band channels
2-69. The tuner will also tune to VHF stations to display NTSC
broadcast signals. Automatic IF gain control and NTSC
interference rejection filter, multipath interference
cancellation and symbol time recovery are some of the advanced
features built into the demodulator.
The decoder section of the ARX-100 is a MPEG2 MP@HL IC that will
decode all 18 ATSC video formats and audio bit streams. The unit
also offers a Dolby digital decoder for audio monitoring. The
picture format converter will interpolate the video bit stream
into one of three formats: 1080i, 720p or 480p for displaying
into a monitor
