Title: Explain the components of common satellite signals.
Course: Telecommunications I (10006-I) > Section: Examining Satellite Communication

Explanation should include

- National Television Standards Committee (NTSC), Phase Alternate Line (PAL), or Sequential Color and Memory (SECAM) television broadcast standards
- quadrature phase shift keying (QPSK) for digitized television signal or multiplex of signals
- digital television using open standards such as moving picture experts group (MPEG)  and Digital Video Broadcasting-Satellite (DVB-S) or Integrated Services Digital Broadcasting-Satellite (ISDB-S)
- conditional access using encryption/scrambling methods
- direct broadcast via satellite, television receive-only, and direct-to-home television.

Process/Skill Questions:

- What are the differences between NTSC, PAL, and SECAM?
- Why is QPSK used with digital signal distribution rather than NTSC, PAL, or SECAM?
- What is the difference between open standards and conditional access?
