ABSTRACT:
In cases where a video signal cannot be normally received, a display apparatus allows a display by which one can recognize whether or not a jamming electric wave in an operation frequency band used for wireless communication makes it impossible to normally receive a video signal. More specifically, the display apparatus is a display apparatus for receiving at least a video signal by wireless communication, the display apparatus, including a wireless receiving unit for receiving the video signal that is wirelessly transmitted; a jamming signal detecting unit for detecting, in an operating frequency band used for the wireless communication, a jamming signal other than the video signal; and a jamming signal information outputting unit for, in response to the detection of the jamming signal, outputting jamming signal information indicating presence of the jamming signal.
