Provided are a screen display method and system for key function icons. The method acquires a size of a screen display area of a device, and acquires preset key function icons corresponding to physical keys of the device and a display mode of the preset key function icons, determines, according to the size and the display mode, display positions of the key function icons on the screen of the device, monitors triggering states of the physical keys of the device, if a physical key of the device is triggered, displays the key function icons at the display positions, thereby improving the accuracy in operating the physical keys of the device.

Systems and methods for generating a gear-based user interface for display are disclosed. A user equipment device may generate for display a first gear shape, a second gear shape, and a third gear shape. The first gear shape comprises a first plurality of media identifiers, where a first media identifier of the first plurality is selected. The second gear shape comprises a second plurality of media identifiers that are representative of a group indicated by the selected first media identifier, where a second media identifier is selected. The third gear shape comprises a third plurality of options for a media asset indicated by the selected second media identifier. Upon input indicating that the first gear shape is to be rotated, the second gear shape is rotated with the first gear shape based on the rotation of the first gear shape.

A display apparatus is provided. The display apparatus includes a display configured to display a user interface window for receiving a letter input; a communication interface configured to receive a control instruction for inputting letters from a control device; and a controller configured to control the display to selectively display an on-screen keypad for inputting letters on the user interface window based on whether the control device includes letter keys for inputting letters.

Systems and methods for mapping keys on a remote control device to digital content items are disclosed. An algorithm is trained, based on user's consumption pattern, to determine whether a digital content item would be relevant to the user. If the digital content item matches the consumption pattern, then a key is automatically mapped, and if it does not, then a notification that includes a mapping suggestion is generated and mapped upon approval. A mapping table is updated to store only valid mappings. An input of a key results in quick display of the mapped digital content item from where it was previously exited.

A key can be mapped to a single or multiple digital content items. If similarities are detected between multiple digital content items, then they may both be mapped to the same key.

A display apparatus is provided. The display apparatus includes a display configured to display a user interface window for receiving a letter input; a communication interface configured to receive a control instruction for inputting letters from a control device; and a controller configured to control the display to selectively display an on-screen keypad for inputting letters on the user interface window based on whether the control device includes letter keys for inputting letters.

Provided are a screen display method and system for key function icons. The method acquires a size of a screen display area of a device, and acquires preset key function icons corresponding to physical keys of the device and a display mode of the preset key function icons, determines, according to the size and the display mode, display positions of the key function icons on the screen of the device, monitors triggering states of the physical keys of the device, if a physical key of the device is triggered, displays the key function icons at the display positions, thereby improving the accuracy in operating the physical keys of the device.

An image display device includes: a processor; a memory configured to store channel information corresponding to at least one channel; and at least one program which is stored in the memory and executed by the processor. The program may include instructions for controlling a display so as to move a channel indicator in a first or second direction on a channel scroll bar and to display channel information of a channel corresponding to a point at which the channel indicator is located, in response to a first input of pressing a channel-up or channel-down key for a long time, and for switching a current channel to the channel corresponding to the point at which the channel indicator is located and displaying an image corresponding to the switched channel, in response to a second input of releasing the channel-up or channel-down key.

A TV audience survey system for determining the TV viewing activities of a plurality of individuals in a household includes a master device and multiple tags, each tag assigned to an individual. After an individual logs into the system and starts watching the TV, the master device communicates with the corresponding tag repeatedly to accumulate data representing the individual's TV viewing activities. Such data can be used to determine when the individual stops watching the TV for an extended period of time without logging out of the system and when the household member remains watching the TV after logging or being logged out of the system. The master device then reports the accumulated data to a remote server, which uses the data to determine whether the individual complies with the logging protocol defined by the TV audience survey system and update the TV viewership data associated with this household.

An electronic apparatus is provided. The electronic apparatus includes a communicator comprising communication circuitry configured to receive a control signal from a remote controller; and a processor configured to determine at least one recommendation key based on a screen corresponding to an image signal and key input history information and to generate a keypad image including a button object in which the at least one recommendation key is arranged to be selectable by a plurality of buttons included in the remote controller.
