Tvro - television receive only
| Telecommunications Glossary |
Earth stations which receive (but not transmit) satellite transmissions. normally comprised of a parabolic antenna, low noise converted (lnc) or low noise amplifier (lna) and a satellite receiver. the antenna gathers the weak signals transmitted from the communications satellite located in the geostationary orbit which are then amplified and downconverted to a more usable portion of the spectrum by the low noise converted. from the lnc the signals may travel up to several hundred feet to a satellite receiver; the output of which is typically video and audio or modulated channel three or four. 23b+d the capability of isdn primary rate interface (pri) to enable data terminals served by a dms-100 isdn node to have fully digital circuit- and packet-switched isdn internetworking with data terminals served by pbxs.

Two-way interactive television, английский
Two-way interactive television provides real-time, two-way visual contact and audio contact between students in two or more classrooms and their instructor/facilitator who may be at one of the sites or a separate origination site. two-way compressed video systems are not all delivered at the same speed. some are full-motion video and some are delivered at slower speed so that the picture and audio are delayed in delivery and do not have the same appearance as full ntsc video. some systems use full fiber optic or t1 lines for delivery while other use a partial t1 or isdn for delivery of the signal. signals are also delivered compressed to a part of glossary/87 a satellite transponder. the reason for using partial lines and partial transponders is to use less bandwidth. less bandwidth for the transmission reduces the cost to deliver the signal.
Tuner, английский
A device, circuit, or portion of a circuit that is used to select one signal from a number of signals in a given frequency range.
