In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
Q: What "mooted" format was viewed as an enhanced television format?, Context: It also includes the alternative 1440×1152 HDMAC scan format. (According to some reports, a mooted 750-line (720p) format (720 progressively scanned lines) was viewed by some at the ITU as an enhanced television format rather than a true HDTV format, and so was not included, although 1920×1080i and 1280×720p systems for a range of frame and field rates were defined by several US SMPTE standards.)
A:
720p
