Thus, some companies are able to provide flexible digital demodulator designs capable of addressing both the 8-level vestigial sideband
(8-VSB) signal for North America as well as the Coded Orthogonal Frequency Division Multiplex (CODFDM) waveform of DVB-T.
The ultra compact system supports both ATSC Vestigial SideBand
and NTSC reception and channel decoding through its chipset.
To transmit the compressed digital signal over an RF carrier, several new digital modulation standards are gaining acceptance, including quadrature amplitude modulation and vestigial sideband
The ITFS transmission is a 2600 MHz vestigial sideband
television signal which is received by the learning centers via a rooftop dish, then down-converted and viewed on a standard TV receiver.
