Display mode switching apparatus, method and program product
View Patent ↗A display mode switching device and method automatically switches a display mode of a television set to an overscan mode or to an underscan mode depending on a content of a screen. In a case of connecting a television set to a computer, a call from an application for an API in an OS is detected by a device driver when a user starts playing a DVD or a game. Accordingly, an output mode for the television set is switched to the overscan mode. In this way, a motion video or a game is displayed on the television set in the overscan mode. Meanwhile, when the user finishes playing the DVD or the game, a call for the API to release resources is detected by the device driver, and the output mode is restored to the underscan mode. In this way, a computer screen is displayed on the television set in the underscan mode.
1. An apparatus comprising:
a content identifier which identifies content to be displayed on a television set; and
a switch, coupled to said content identifier, which switches an output mode for the television set to an overscan mode or to an underscan mode depending on a result of identification obtained by said content identifier;
wherein said content identifier identifies that the content to be displayed on the television set is any one of a motion video and a game by detecting a call for a given application program interface from any one of a motion video player application and a game application, and
said switch automatically switches the output mode for the television set to the overscan mode on condition that the content to be displayed on the television set is identified as any one of the motion video and the game.
2. A method comprising:
a content identifying step of identifying a content to be displayed on a television set; and
a switching step of switching an output mode to the television set to an overscan mode or to an underscan mode depending on a result of the content identifying step;
wherein said identifying and switching are performed by a device driver stored in a computer-readable recording medium;
wherein the content identifying step further comprises a step of identifying that the content to be displayed on the television set is any one of a motion video and a game by detecting a call for a given application program interface from any one of a motion video player application and a game application, and
the switching step further comprises a step of automatically switching the output mode for the television set to the overscan mode on condition that the content to be displayed on the television set is identified as any one of the motion video and the game.
3. A product comprising:
a computer-readable recording medium having computer readable program code stored therein, the computer readable program code in said product causing a computer to execute:
a content identifying step of identifying a content to be displayed on the television set; and
a switching step of switching an output mode for the television set to an overscan mode or to an underscan mode depending on a result of identification obtained by the content identifying step;
wherein the content identifying step further comprises a step of identifying that the content to be displayed on the television set is any one of a motion video and a game by detecting a call for a given application program interface from any one of a motion video player application and a game application, and
the switching step further comprises a step of automatically switching the output mode for the television set to the overscan mode on condition that the content to be displayed on the television set is identified as any one of the motion video and the game.
4. An apparatus comprising:
a processor; and
a device driver operatively coupled to the processor and stored in a computer-readable recording medium, the device driver comprising:
a content identification unit configured to identify content to be displayed on a display device; and
a switching unit, coupled to said content identification unit, configured to automatically switch an output mode for the display device to an overscan mode or to an underscan mode depending on identified content to be displayed;
wherein the content identification unit is configured to identify the content to be displayed by detecting a call for an application program interface from any one of a motion video player application and a game application.
