Apparatus for receiving and selecting high-definition television (HDTV) signals and standard television (NTSC) signals

摘要

An apparatus for receiving and selecting high-definition television signals and NTSC standard television signals includes a high-definition display screen device having an aspect ratio of 16 to 9. The NTSC standard television signals have an aspect ratio which is different than the 16 to 9 aspect ratio of the high-definition display screen device. A first signal converter is for converting the NTSC standard television signals into first quasi-high-definition television signals identifying a first displayed image corresponding in vertical length to a vertical length of the high-definition display screen device. A second signal converter is for converting the NTSC standard television signals into second quasi-high-definition television signals identifying a second displayed image corresponding in horizontal length to a horizontal length of the high-definition display screen device. Switching circuits are provided for selecting one of the high-definition television signals and the first and second quasi-high-definition television signals.
