CATV network evolution

Abstract

Cable television (CATV) distributions are transmissions systems assigned for received and distribution televisions (TV) and radios (R) signals. This paragraph is about individual stages of evolution of this distribution. It begins by classic CATV network by using coaxial cable then it continues by modernization of optical fibre. It describes structure and two-way communication of interactive TV cable distribution frame and it describes intelligence of this network. By implementation interactivity we can not understand it as the CATV network as only distributions system which transfers only TV and R signals but like multifunctional system which can transfer information by both directions.
