WSNET Offers QAM Digital Video Solution.NAA/NSC member WSNet announced that it now offers its network of multiple dwelling unit (MDU (1) (Multiple Dwelling Unit) A commercial or residential building with multiple offices or apartments. See BLEC. (2) (Multiply-Divide Unit) A high-speed circuit that performs multiplication and division within the CPU. ) service providers digital video via Quadrature Amplitude Modulation See QAM. Quadrature Amplitude Modulation - (QAM) A method for encoding digital data in an analog signal in which each combination of phase and amplitude represents one of sixteen four bit patterns. This is required for fax transmission at 9600 bits per second. (QAM (1) (Quality Assessment Measurement) A system used to measure and analyze voice transmission. (2) (Quadrature Amplitude Modulation) A modulation technique that employs both phase modulation (PM) and amplitude modulation (AM). ), one of the most cost-effective methods of providing 200 channels of digital satellite television to apartment complexes, condominiums, townhomes, retirement communities, nursing homes, marinas, RV parks, university dormitories and new housing developments. QAM allows MDU service providers to use a building's existing cable wiring, saving hundreds of dollars in installation expenses. QAM also eliminates the requirement of having a satellite antenna or "dish" on each MDU building. QAM uses satellite signals that have been converted from QPSK/L-Band satellite signals; a digital modulation standard used by the cable television industry. This cost-effective conversion, which occurs at the headend, allows the delivery of WSNet's digital programming using 18 transponders and only 108 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. of bandwidth. This method of QAM distribution is compatible with 330, 450, 550 and 750 MHz CATV (Community Antenna TV) The original name for cable TV. It used a single antenna at the highest location in the community in order to deliver a quality signal to homes in areas with hilly terrain or other interference. systems. WSNet's digital satellite television service distributes basic and specialty programming to the private cable and wireless cable industries. WSNet's comprehensive digital television service offers nearly 200 channels, including more than 80 basic video channels, 41 premium multiplex services, 37 channels of digital music, as well as pay-per-view and international programming. |
