8-VSB

(8-level Vestigial SideBand) The modulation technique used for digital TV (DTV) in the U.S. It minimizes interference with analog NTSC signals, which must be transmitted simultaneously with the digital signals until 2006. NTSC uses an analog VSB modulation. See DTV. Contrast with OFDM.

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.
The ATSC-compatible DRX3931J is based on Micronas's primeD(R) demodulator technology, the field-proven "ghost friendly" 8VSB demodulator technology from Micronas.
The DTS-330 and DTS-200 are able to support several different combinations of inputs and outputs, such as QPSK, ASI, full bandwidth GigE, SMPTE-310, DHEI, QAM, COFDM and 8VSB.
The DTV 720 can be equipped with up to four (4) ASI inputs to process live satellite feeds and up to (2) internal 8VSB and QAM tuners for local off-air broadcast TV signals.
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.
WEGENER provides telecom operators IP multicasters, high quality satellite receivers and 8VSB digital television demodulators for easy integration of an IPTV headend.
Reference design includes both 8VSB and QAM demodulators to allow compatibility with both ATSC and Digital-cable-in-the-clear sources.
Additionally, RF confidence monitoring interfaces including COFDM, 8VSB, Turbo 8PSK, QPSK (L Band), and QAM allow the MTM400 to receive RF inputs and display key RF monitoring parameters including MER, BER, and constellation displays before demodulating the signal to provide measurements on the health of the Transport Stream.
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.
Other features include PIP, POP, CC, V-Chip, Noise Reduction, 3D Comb Filter, Zoom, Freeze, Motion Adaptive De-Interlacing, 3:2 Pull Down, ATSC with 8VSB & QAM demodulation, MPEG-2 decoding, NTSC Video decoding via RF (Antenna, Cable, or Satellite) or Video (CVBS, S-Video or Component), Progressive Scan Video via Component, YPbPr, VGA or HDMI, HDTV via HDMI or Component YPbPr, Computer 640x480, 800x600, 1024x768 via VGA or 640x480 via HDMI.
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.
