How is color information sent in analog SSTV?
- A.Color lines are sent sequentially (correct answer)
- B.Color information is sent on a 2.8 kHz subcarrier
- C.Color is sent in a color burst at the end of each line
- D.Color is amplitude modulated on the frequency modulated intensity signal
WhyAnalog SSTV sends color information by transmitting each color line sequentially. Analog SSTV sends color pictures by transmitting the red, green, and blue (or similar) color component for each line one after another in sequence, rather than all at once, answer A. There's no 2.8 kHz color subcarrier or end-of-line color burst the way analog broadcast color TV works, and color in SSTV isn't amplitude-modulated onto an FM intensity signal.
