Video Modulation and Transport
Chapter Outline
Video compression is often performed to reduce the data rate, or bandwidth, necessary for transport. Video is sent over satellite, fiber, coax or copper twisted-pair wires. In practice, multiple video signals are often sent over the same medium simultaneously.
17.1 Complex Modulation and Demodulation
Modulation is the process of taking information bits and mapping them to symbols.
This sequence of symbols is filtered to produce a baseband waveform with the desired spectral properties. The baseband waveform or signal is then ...
