  • 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 Innovation Lab.

    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 section.

    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," Romeo said.

    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
