Abstract
A method of determining the status of a plurality of input ports in a television receiver having a plurality of signal input ports, and including a main-screen signal processor and a sub-screen signal processor, automatically verifies the presence or absence of an input signal at each signal input port. The port status determining method includes detecting signal presence at each of the plurality of signal input ports via the sub-screen signal processor to determine whether the corresponding input signal exists, by sequentially setting an input mode in correspondence to each of the plurality of signal input ports; and recognizing as a valid input port each signal input port at which signal presence is detected.
Claims24
A method of determining port status in a television receiver including a plurality of signal input ports and including a main-screen signal processor for displaying a first image on a main screen of the television receiver and a sub-screen signal processor for displaying a second image on a sub-screen of the main screen, the method comprising:
- detecting a signal presence at at least one of the plurality of signal input ports via the sub-screen signal processor, to determine whether the corresponding input signal exists, by sequentially setting an input mode in correspondence to at least one of the plurality of signal input ports;
- recognizing as a valid signal input port where the signal presence is detected;
- and
- displaying OSD information indicative of the recognized valid signal input port for distinguishing between a valid signal input port and an invalid signal input port,
- wherein the displayed OSD information includes at least one valid signal input port and at least one invalid signal input port, and the valid signal input port is distinguished from the invalid signal input port by using a different marking or a highlight.
A method of determining port status in a television receiver including a plurality of signal input ports and including a main-screen signal processor for displaying a first image on a main screen of the television receiver and a sub-screen signal processor for displaying a second image on a sub-screen of the main screen, the method comprising:
- identifying a valid signal input port by sequentially detecting, via the sub-screen signal processor, a signal presence of one of the plurality of signal input ports that has been determined to be a preliminarily confirmed signal input port;
- and
- displaying OSD information indicative of the identified valid signal input port for distinguishing between a valid signal input port and an invalid signal input port.
- wherein the displayed OSD information includes at least one valid signal input port and at least one invalid signal input port. and the valid signal input port is distinguished from the invalid signal input port by using a different marking or a highlight.
A television receiver, comprising:
- a plurality of signal input ports for respectively receiving a corresponding plurality of input signals, each input signal corresponding to a peripheral device configured to supply a video signal to the television receiver;
- a key signal input unit for generating a first selection signal for selecting a main screen signal and a second selection signal for selecting a sub-screen signal;
- a first signal processor for processing the selected main screen signal in response to the first selection signal;
- a second signal processor for processing the selected sub-screen signal in response to the second selection signal;
- and
- a controller for sequentially setting an input mode in correspondence to each of the plurality of signal input ports and for recognizing as a valid signal input port by detecting a signal presence at at least one of the plurality of signal input ports via said second signal processor to determine whether the corresponding input signal exists, and for controlling a display of OSD information indicative of the recognized valid signal input port for distinguishing between a valid signal input port and an invalid signal input port,
- wherein the displayed OSD information includes at least one valid signal input port and at least one invalid signal input port, and the valid signal input port is distinguished from the invalid signal input port by using a different marking or a highlight.
