Apparatus and method for converting an HDTV signal to a non-HDTV signal

A digital video signal reception apparatus comprising:

• multiplexer selection control means for outputting a plurality of control signals according to a format of a compressed input digital video signal;
• decoding means for decoding the compressed input digital video signal;
• frame rate conversion means for converting a frame rate of the decoded digital video signal from said decoding means into a desired value under the control of said multiplexer selection control means;
• decimation means for performing a decimation operation to convert the number of horizontal scanning lines of an output video signal from said frame rate conversion means into a desired value;
• display mode conversion means for performing a display mode conversion operation so that an output video signal from said decimation means can be displayed in a desired display mode;
• and
• display processing means for displaying an output video signal from said display mode conversion means on a screen of a monitor.
