Apparatus for converting frame format of a television signal to a display format for a high definition television (HDTV) receiver

摘要

An apparatus for converting a frame format of a television signal to a display format includes a scanning format conversion circuit for converting a scanning format of an input video signal to a progressive scanning type if it is of an interlaced scanning type, a scanning line conversion circuit for converting the number of vertical scanning lines of an output video signal from the scanning format conversion circuit to that of the display format, a horizontal pixel conversion circuit for converting the number of horizontal pixels of an output video signal from the scanning line conversion circuit to that of the display format, and a format control circuit for controlling the scanning format conversion circuit, the scanning line conversion circuit and the horizontal pixel conversion circuit to convert a frame format of the input video signal to the display format.
