Abstract: A display device includes a touch screen having a display surface that displays images. The touch screen outputs a signal indicating a position on the display surface that has been touched. The display device also includes a first sensor that senses a position of an object relative to the display surface. The display device further includes a controller that generates a virtual keyboard image including a plurality of virtual keys for display on the display surface. The controller generates a left side portion and a right side portion of the virtual keyboard image, and chooses, as a display portion, one of the left side portion and the right side portion of the virtual keyboard image corresponding to the position of the object relative to the display surface as sensed by the first sensor. The controller controls the touch screen to display the display portion on the display surface.

Abstract: A digital television receiver for use in a digital television broadcast system in which a plurality of digital television data streams can be provided in respective streams of television broadcast packets forming the lowest layer of a layered digital television structure and also in respective streams of Internet protocol packets forming the lowest layer of a layered Internet protocol structure, the streams of television broadcast packets being broadcast with a plurality of tables indicating where data of one layer of one structure can be found in another layer of one or other of the two structures, the received plurality of tables being used to determine where data contained in one layer can be found in an adjacent layer so as to construct tree structures or a new table allowing determination of in which stream of television broadcast packets the television data of a selected stream of Internet protocol packets is found.

Abstract: A demodulator device and a method of operating the demodulator device where the demodulator device runs a loaded operating system and operates a communication protocol enabling a host application to control the demodulator device. The demodulator device is configured to respond to receipt of an abort command of the communication protocol by carrying out an abort process which stops current operations and reinitializes the loaded operating system.

Abstract: The present invention relates to an apparatus and method for producing an EPG from program information in an EPG database for a plurality of channels. The EPG displays items relating to the programs available on a plurality of channels at a specified time. When the specified time is changed, the EPG updates the items corresponding to channels on which the available program is not the same at the newly specified time as at the previously specified time.

Abstract: A system having a plurality of hardware blocks and a method of operating that system where power to each hardware block is independently controlled according to whether or not the respective hardware block is needed for use. A counter is provided in the respective device driver of each hardware block, the counter being configured to be incremented each time a task requests use of the respective hardware block and to be decremented each time a task ceases use of the respective hardware block. The value of the counter is used to control whether or not to power up or power down the respective hardware block.
