- direct broadcast via satellite, television receive-only, and direct-to-home television.

- 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?
