Patent ID: 7268828

Claim:
A television receiver comprising: a switching portion which receives each of a video signal received and obtained by an antenna and a video signal read from a storage medium, and selectively outputs one of the video signals in response to an instruction signal for output selection; a detection portion configured to receive a video signal selected and output by the switching portion and to detect a mode of the received video signal; a selection/control portion configured to supply the instruction signal for output selection to the switching portion, and to forcibly cause the detection portion to output a detection result corresponding to a preset specific mode without permitting the detection portion to detect the mode of the received video signal, when the instruction signal is a signal for selecting the video signal read from the storage medium; a signal processing portion which applies sequential scanning conversion processing corresponding to the mode detected by the detection portion to the video signal selected and output by the switching portion; and a display portion which displays the video signal subjected to the sequential scanning conversion processing in the signal processing portion.
