Exploring Cable TV and Internet Systems
Broadcast TV
• The global telecommunications system is made up of many subsystems such as: • Prior to the 1950s, information was primarily delivered over fixed lines or radio broadcasts.
• Fixed--line telephone systems
• Toward the end of the 1940s and during the 1950s, the television broadcast infrastructure began to develop.
• Cable TV systems
• Internet systems
• During that time, the primary method employed to deliver TV broadcasts to consumers was radio waves.
4
• One critical limitation in the TV broadcast system is range.
• One solution to this problem is community antenna television
(CATV), more commonly known as cable TV.

Community Antenna Television
Headend
• The early generations of CATV may have simply consisted of an antenna placed on the highest point, such as a hilltop.
• In a cable TV system, headend refers to the main building or facility that contains the receiving antennas. • As CATV systems matured, amplifiers were added to boost the
signal
