Earlier this year the FCC voted on a plan to fix crappy cable boxes. Dubbed "Unlock the Box," the plan would make cable companies open up their services for use on boxes made by other companies.
The Cimple TV Antenna Amplifier is a powerful distribution amplifier with an adjustable gain feature that reaches up to 24 decibels. Simply turn the adjustment knob to the amount of gain needed ...
Some of the systems used for cable feed distribution were expensive. As the DTH market grew, less secure systems began to be used. Many of these systems (such as Oak Orion) were variants of cable television scrambling systems that affected the synchronisation part of the video, inverted the video signal, or added an interfering frequency to the ...
Most digital video signals are compressed to MPEG-2 and MPEG-4 formats in order to combine multiple video streams into a QAM making the most efficient use of spectrum which a customer cable set top box receives, demodulates, de-encrypts and displays as a virtual channel number that the viewer recognizes. In many cases the same TV network may ...
An audio distribution amplifier also known as: a press feed; a pool feed; a media feed; press box; or an ADA, takes a single audio feed, usually a line input, but it may be a microphone input, and outputs multiple line or microphone outputs. This can be done using a passive feed, where the signal is split among the outputs, or as an active feed ...
An addressable cable box is one that can be controlled by the local cable company. Addressability is the process by which (optionally encrypted) messages are sent from the cable provider for a particular cable box via the cable signal. The cable company can "address" a particular customer's cable box to command it to activate or deactivate the ...
A system involving the use of a high-pass filter on the line to prevent two-way communication has been widely promoted by some businesses as a means of disabling communication of billing information for pay-per-view programming but this device is effectively worthless as a cable operator remains free to unsubscribe a digital set-top box if two ...
In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead cable. An antenna amplifier boosts a radio signal considerably for devices that receive radio ...
