The present disclosure describes a sensing technology. A pattern code recognition multimedia playback apparatus and driving method therefor according to some embodiments recognize pattern code by using pattern code recognition pen, extract multimedia data corresponding to the recognized pattern code from pattern code recognition set-top box, and control playback of the multimedia data, thus easily calling multimedia data stored in memory pack attached to the pattern code recognition set-top box with the pattern code recognition pen for recognizing pattern code printed on pattern code-printed material and promptly and easily watching the multimedia data played through display unit. The present disclosure provides various curriculums including animation, storytelling, dancing, and the like, to allow infants or preschool children to easily access contents to learn described in studying materials through the display unit, thus improving learning efficiency of the kids and assisting intelligence development, personality development, and emotion development.

An operation-mode conversion apparatus for an image display compound device includes a power-state detector which detects a power state of the compound device, an operation-mode determination unit which determines a present operation mode of the compound device, and an operation-mode controller which converts the operation mode of the compound device based on the power state, the present operation mode, and whether one of an optical storage medium and a movable memory is detected by the compound device, in response to a user input signal, regardless of the preset operation mode.

A display device is disclosed. The display device includes a display, a communication interface comprising circuitry, a storage configured to store combined information on contents available from a plurality of input sources, and a processor configured to control the communication interface to receive an external input signal from the plurality of input sources, display, through the display, recommendation information on a content available through a first input source from among the plurality of input sources based on a viewing history of a user and the combined information stored in the storage, the viewing history of the user is a viewing history related to an external input signal provided through a second input source from among the plurality of input sources.

Systems and methods are provided reducing storage space occupied by a media asset by adjusting quality levels of the media asset downward over time. This may be accomplished by a media guidance application that store, at a given time, the media asset in a first format having a first quality level. The media guidance application retrieves, from a database, a data entry corresponding to the media asset and determines, based on the data entry, a threshold period of time for storing the media asset in the first format. The media guidance application detects whether the threshold period of time since the given time has passed and responds by altering a first portion of the media asset from the first format having the first quality level to a second format having a second quality level that is inferior to the first quality level.

As an embodiment of the present invention, there is provided an information terminal comprising: an input/output part for performing input and output with respect to an image storage device for storing image information captured by an imaging terminal; a storage part for associating and storing image identification information for identifying the image information, summary image information that includes less information than the image information, and device identification information for identifying the image storage device; and a display part; wherein the device identification information stored in the storage part is displayed by the display part, the summary image information that is associated with device identification information selected from the device identification information displayed by the display part is displayed by the display part, and the image information associated with the summary image information selected from the summary image information displayed by the display part is displayed by the display part.

According to one embodiment, a memory system includes a non-volatile semiconductor memory device, a control unit, a memory as a work area, a wireless communication module, and an extension register. The control unit controls the non-volatile semiconductor memory device. The extension register is provided in the memory and has a data length by which a wireless communication function of the wireless communication module can be defined. The control unit causes the non-volatile semiconductor memory device to store, as a file, an HTTP request supplied from a host, causes the extension register, based on a first command supplied from the host, to register an HTTP transmission command transmitted together with the first command, and causes the wireless communication module to transmit the HTTP request stored in the non-volatile semiconductor memory device based on the transmission command registered in the extension register.

A system that incorporates teachings of the present disclosure may include, for example, a presentation device having a controller that performs operations including enabling a supply of power to a portable battery operated device from a presentation port where the presentation port is a high definition multimedia interface port by trickle charging a rechargeable battery of the portable battery operated device through the presentation port, and receiving from the portable battery operated device an audio-visual signal for presentation at the presentation device through the presentation port. Other embodiments are disclosed.

A function upgrade device, a display apparatus, and a method for controlling a display apparatus are provided. The function upgrade device may include a function unit configured to perform a function in conjunction with the display apparatus, a storage configured to store user information and an application related to the function unit, an interface configured to connect the function upgrade device to the display apparatus and enable the function upgrade device to communicate with the display apparatus, and a controller configured to, when the display apparatus is connected to the function upgrade device through the interface, control the function unit to operate in conjunction with the display apparatus based on the user information and the application stored in the storage.

According to one embodiment, a memory system includes a non-volatile semiconductor memory device, a control unit, a memory as a work area, a wireless communication module, and an extension register. The control unit controls the non-volatile semiconductor memory device. The extension register is provided in the memory and has a data length by which a wireless communication function of the wireless communication module can be defined. The control unit causes the non-volatile semiconductor memory device to store, as a file, an HTTP request supplied from a host, causes the extension register, based on a first command supplied from the host, to register an HTTP transmission command transmitted together with the first command, and causes the wireless communication module to transmit the HTTP request stored in the non-volatile semiconductor memory device based on the transmission command registered in the extension register.
