An audio/video plug detecting apparatus applied in an audio/video apparatus, wherein the audio/video apparatus outputs a plurality of audio/video signals, the audio/video plug comprises a plurality of contact sections, and the detecting apparatus comprises:
- a jack for accommodating the audio/video plug;
- a placement detector for detecting whether the audio/video plug has been loaded into the jack;
- a section number detector for detecting the number of the contact sections of the audio/video plug;
- a controller for determining a plurality of possible output arrangements according to the detected number of the contact sections, wherein the possible output arrangements define different arrangements of the audio/video signals to be outputted selectively to the contact sections of the audio/video plug;
- and
- a display circuit for displaying a menu of the possible output arrangements on the audio/video apparatus for selection of one of the possible output arrangements as an active output arrangement from the menu so that the audio/video signal are outputted to the contact sections of the audio/video plug via the jack according to the active output arrangement.
An audio/video plug detecting method applied in an audio/video apparatus, the audio/video apparatus having a plurality of contact sections for outputting a plurality of audio/video signals, the detecting method comprising:
- detecting whether the audio/video plug has been loaded;
- determining the number of the contact sections of the audio/video plug;
- displaying a menu according to the determined number of the contact sections, wherein the menu comprises a plurality of possible output arrangement options of the audio/video signals for a user to select an active output arrangement from the possible output arrangement options, wherein the possible output arrangement options correspond to different arrangements of the audio/video signals to be outputted selectively to the contact sections of the audio/video plug;
- and
- outputting the audio/video signals to the audio/video plug according to the active output arrangement.
A detecting apparatus applied in an audio/video apparatus, wherein the audio/video apparatus can output a plurality of audio/video signals to a first audio/video plug comprising three contact sections or a second audio/video plug comprising four contact sections, while the detecting apparatus comprises:
- a jack for accommodating either of the first audio/video plug and the second audio/video plug;
- a section number detector for detecting the number of the contact sections of an active audio/video plug connected with the jack, wherein the active audio/video plug is either the first audio/video plug or the second audio/video plug;
- a controller for determining a plurality of possible output arrangements according to the detected number of the contact sections, wherein the possible output arrangements define different arrangements of the audio/video signals to be outputted selectively to the contact sections of the active audio/video plug;
- and
- a display circuit for displaying a menu showing the possible output arrangements on the audio/video apparatus for selection of an active output arrangement from the possible output arrangements so that the audio/video signal are outputted to the contact sections of the active audio/video plug via the jack according to the active output arrangement.
