Harris Corporation Introduces QAM Capabilities in its DDM-800 Digital Demodulators

CINCINNATI — Harris Corporation (NYSE:HRS) today announced the availability of its updated Videotek® DDM-800 Digital Demodulator, which now includes QAM (quadrature amplitude modulation) in support of cable TV and 8VSB (terrestrial digital/HDTV) demodulation capability. The DDM-800 can now demodulate 64 QAM and 256 QAM (QAM ITU-TJ83 Annex B) modulated signals, used extensively by cable providers, and convert them to DVB-ASI output format. The demodulated MPEG-2 output streams can then be locally decoded, analyzed, multiplexed or passed to a cable facility via QAM modulators or to a data distribution network. These additional QAM capabilities make the DDM-800 well-suited for clear channel applications via cable or 8VSB off-air systems.

"The cable market presents many opportunities for us, and enhancements such as this recent addition to our demodulator line will help us stay ahead of the competition and provide our customers with added value," said Tim Thorsteinson, president-elect of Harris Broadcast Communications Division. "With the flexibility to add three optional demodulators to its base 1RU unit, the DDM-800 provides a space-efficient and economical solution for cable, satellite and broadcast facilities."

The Harris Videotek® product line has been supplying the market with high-performance TV demodulators at the lowest cost to the industry for more than 30 years. With a range of models to support applications from basic monitoring through full FCC proof-of-performance testing, Harris Videotek® has become one of the largest brands of frequency agile demodulators in North America. All analog models provide video and BTSC stereo signal demodulation for off-air broadcast, CATV and closed-circuit monitoring applications. 8VSB demodulators use advanced digital technology to provide transport stream outputs. High-definition, standard-definition, and analog MPEG-2 decoding features are available in select products.
