Two-way interactive television
| Telecommunications Glossary |
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.

Interactive, английский
- Any application that allows the participants at distant locations to communicate with each other; may indicate two-way video and two-way audio; one-way video and two-way audio through a normal telephone call placed to the origination site; asynchronously (not in real time) as through computer conferencing such as an electronic mail system; or through interaction with a teaching machine such as a glossary/43 computer which is programmed to respond to the user with messages on the screen, voice or other sounds to indicate that an answer is right or wrong.
- The active participation of the user in directing the flow of the computer or video program.

Television, английский
- Телевидение; телевизионный
- The electronic transmission of pictures and sounds.
- Телевидение
- An electronic system of transmitting transient images of fixed or moving objects together with sound through space by an apparatus that converts light and sound into electrical waves and reconverts them into visible light rays and audible sound.
Instructor, английский

Facilitator, английский
- In adult education (androgogy), the person responsible for a class who acts as a guide and resource to the students. the person responsible for the local component of a video teleconference site is normally called a facilitator.

- Сотрудник органов образования, в обязанности которого входит распространение передового педагогического опыта
- What a facilitator does is plan, guide and manage a group to ensure that the group’s objectives are effectively met, with clear thinking, good participation and full buy-in from everyone involved. a facilitator brings the participants from known to unknown.

- Создание
- The making of mortgage loans.
- Начало работы над проектом
Compressed, английский
- Сжат; уплотнен
- A sound, recorded track, or mix where the dynamics are restricted or narrowed.

- Явка (в суд)
Transponder, английский
- An airborne transmitter that responds to ground-based interrogation signals to provide air traffic controllers with more accurate and reliable position information than would be possible with "passive" radar; may also provide air traffic control
- Transmitter-respon- der (beacon)
- The part of a satellite that receives and transmits a signal.
- An electronic transmitter which identifies itself in response to interrogation by another transmitter.
Transmission, английский
- Passage of electromagnetic radiation through a medium.
- Transmisión
- The property in a merchantman, or a share therein, transmitted in
- Передача; привод; коробка передач; трансмиссия; прохождение; распространение ~ of loads передача нагрузок
- The transport of high voltage electricity. this is achieved with a transmission network (or grid). generally the network will connect large generators to lower voltage distribution networks where it will be transported to the majority of electricity consumers. alternatively, large scale electricity users may connect directly to the transmission network. management of transmission is a natural monopoly due to the economies of scale inherent to it. transmission system operator (tso) (also transmission network operator-

Two-wire circuit, английский

Tvro - television receive only, английский
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.
