Any converter box converts the digital signal for the current digital sub-channel to an analog signal (at the reduced screen resolution of the analog standard), outputs that signal onto analog channel 3 or 4 (set by the user to avoid any conflict with local over-the-air channels) and sends that signal to the analog tuner on the TV. With a box ...
A low-noise block downconverter (LNB) is the receiving device mounted on satellite dishes used for satellite TV reception, which collects the radio waves from the dish and converts them to a signal which is sent through a cable to the receiver inside the building.
The input digital signal may be over-the-air terrestrial television signals received by a television antenna, or signals from a digital cable system. It normally does not refer to satellite TV , which has always required a set-top box either to operate the big satellite dish , or to be the integrated receiver/decoder (IRD) in the case of direct ...
The term breakout box is derived from the mechanical enclosure in which a connector's aggregate connections are separated (i.e., broken out) into the individual signal or current-carrying wires or cables. Often, if there are only a few connections, then a breakout cable (also called an octopus cable) may be used, as is common on notebook computers.
A coaxial cable used to carry cable television onto subscribers' premises A set-top box, an electronic device which cable subscribers use to connect the cable signal to their television sets. Presented unit is a Cisco RNG200N for QAM digital cable television system used in North America.
That cable would then run from the roof into the house. At a convenient point, a second diplexer would split the two signals apart; one signal would go to the TV set and the other to the IRD of the DBS set-top box. These usually have an antenna input and a diplexer, so that the antenna signal is also distributed along with the satellite.
Changes in signal reception from factors such as degrading antenna connections or changing weather conditions may gradually reduce the quality of analog TV. The nature of digital TV results in a perfectly decodable video initially, until the receiving equipment starts picking up interference that overpowers the desired signal or if the signal ...
That is, the antennas might both pick up the same station; the signal from the one with the shorter cable will reach the receiver slightly sooner, supplying the receiver with two pictures slightly offset. There may be phasing issues even with the same length of down-lead cable. Band-pass filters or signal traps may help to reduce this problem.
