5.3 DISEQC SWITCH TEST
DiSEqC (Digital Satellite Equipment Control), is a special communication protocol for use between a satellite receiver and a
device such as a multi-dish switch or a small dish antenna rotor.
Single-cable distribution (Unicable) is a satellite TV technology that enables the delivery of broadcast programming to
multiple users over a single coaxial cable, and eliminates the numerous cables required to support consumer electronics
devices.
A digital channel-stacking switch (dCSS) IC is a multiple-input multiple-output device. It typically has N 1.2 GHz inputs that
can be cascaded to additional chips as required (to expand output capacity). These inputs are fed into a large N-pole M-
Throw switch that outputs to M mixers. Each mixer path then translates only the user requested transponder to a
predetermined fixed frequency within the 950-2150 MHz band. This fixed frequency is unique for each tuner on the single
cable output. Each tuner in the STB always stays at this fixed frequency while the dCSS IC translates the user requested
content down the cable to this exact frequency. This architecture requires no hardware change to the STB design.
