Abstract: A line tripler for an NTSC/HDTV dual receiver includes a control signal generation section for generating write enable signals and read enable signals. A FIFO line memory section writes each line of an NTSC video signal three times at a predetermined write sampling rate in response to the write enable signals from the control signal generation section to triple each line. The memory section sequentially outputs the stored three lines of the NTSC video signal at a predetermined read sampling rate in response to the plurality of read enable signals from the control signal generation section.

A format of the NTSC signal can be converted into an HDTV format of 16:9 or 4:3 aspect ratio.
