Several systems were proposed as the new standard for the US, including the Japanese MUSE system, but all were rejected by the FCC because of their higher bandwidth requirements. At this time, the number of television channels was growing rapidly and bandwidth was already a problem. A new standard had to be more efficient, needing less bandwidth for HDTV than the existing NTSC.
Why did the FCC reject systems such as MUSE? What was increasing and consuming a lot of bandwidth? Who rejected systems such as MUSE as the new standard for the US? What was one of the requirements for a new standard system in the US? What was the existing system at the time?
