ABSTRACT:
A broadcasting mode name display apparatus is disclosed. A broadcasting mode detector selects the broadcasting channel and detects the broadcasting mode of a video signal. A mode converter converts a conventional broadcasting mode into a high definition mode. If the mode converter receives a high definition mode signal instead, it is passed as it is. A recorder records the video signal, together with a mode identification signal representing the correspondingly detected broadcasting mode, on a recording medium. A reproducer and detector reproduces the video signal from the recording medium and simultaneously detects the mode identification signal. A switching portion selectively outputs the video signal from either the mode converter or the reproducer and detector according to a control signal. A microprocessor supplies the control signal, the value of which is based on the operation mode of the apparatus, to the switching portion. The microprocessor generates a further control signal representing the broadcasting mode of the video signal. An OSD block generates an OSD signal prompting display of the broadcasting mode on a display screen in response to receiving the further control signal of the microprocessor.
