This document summarizes two modern communication mediums: Direct Broadcast Satellite (DBS) television and Internet Protocol Television (IP-TV). It describes how DBS uses satellites to deliver digitally compressed TV programs to viewers worldwide. It also explains the components of a DBS system, including programming sources, broadcast centers, satellites, dishes, and receivers. For IP-TV, it defines it as digital television services delivered via internet and outlines the technologies used like broadband and digital subscriber lines. It provides examples of content and services offered by IP-TV like video on demand, interactive TV, and voice calls.
This document discusses satellite networks and provides information on various types of satellite orbits including GEO, MEO, and LEO. It describes key aspects of different satellite systems such as how GPS uses MEO satellites in six orbits to enable location services through trilateration. The summary also outlines some advantages and disadvantages of using satellite networks for communication.
