Offering the highest level of integration and performance of any solution on the market today, the DRX-H integrates an ATSC A/53-compliant 8VSB
demodulator with an ITU-T J.
In addition to performing MPEG transport analysis and monitoring for interface points carrying 8VSB
or COFDM modulated terrestrial broadcast RF signals, this interface also provides the important function of RF analysis of the DTTV signal, allowing customers to determine whether or not the problem exists in the digital video service or in the DTTV transmission.
83B/SCTE DVS-031 compliant 64 QAM or 256 QAM modes used by digital cable systems, the NTSC analog system, or the ATSC compliant 8VSB
mode used in digital terrestrial broadcasting.
Reference design includes both 8VSB
and QAM demodulators to allow compatibility with both ATSC and Digital-cable-in-the-clear sources.
In Q4 2004, USDTV will introduce a next-generation set-top box featuring Zenith's fifth-generation 8VSB
reception technology from LG Electronics and MPEG4 compression, which will enable the company to introduce new services, such as VOD and digital video recording (DVR) capabilities.
THEATER 313 will enable LG Innotek to provide compact tuners that convert RF in the form of 8VSB
(vestigial sideband), 64/256 QAM (quadrature amplitude modulation) and NTSC (National Television Standards Committee), outputting MPEG2, CVBS and I2S.
The DHDC-D receives the 8VSB
signal, downconverts it to IF and then feeds it to the DHDC-U.
83B/SCTE DVS-031 compliant 64 QAM (quadrature amplitude modulation) or 256 QAM modes used by digital cable systems, the NTSC analog system, or the ATSC compliant 8VSB
(vestigal sideband) mode used in digital terrestrial broadcasting.
The award presented yesterday evening during a ceremony in New York City was given to Thales Broadcast & Multimedia for the pioneering development of Digital Modulator Adaptive Pre-Correction for ATSC 8VSB
Digital Transmitter Systems(1).
