Video is the electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. The video was first developed for mechanical television systems, which were quickly replaced by cathode ray tube systems which were later replaced by flat panel displays of several types.

MATV stands for Master Antenna Television. It’s the way reception in large buildings such as hotels, schools, office blocks and apartment blocks is conveyed to every TV in the building, using a single master TV antenna.

In simplified terms, an MATV system is made up of two main sections.

There is the ‘head end’, which is the TV antenna portion of the system, and the distribution The system, which is the network of cables that delivers the signal. These two parts are configured to the number of individual dwellings and floors of a building so each TV receives quality reception.
