Abstract: A display apparatus includes a receiver, an image processor, a display and a controller. The receiver receives an image of content in the form image segments. The image processor processes the image of content received via the receiver. The display displays the processed image of content. The controller controls the image processor to display an image corresponding to one viewpoint of the image of content, and display information about a display quality of at least one image segment based on reception states of the image segments. With this, the display apparatus may provide the information about display quality for the at least one segment of the image of content, thereby allowing a user to watch the image of content while smoothly moving a viewpoint.

Abstract: A digital multimedia reproducing apparatus capable of receiving and providing digital multimedia broadcasting (DMB) in addition to reproducing moving pictures and music, and a DMB providing method performed in the digital multimedia reproducing apparatus, the digital multimedia reproducing apparatus including: a tuner unit to receive a digital broadcasting signal via a predetermined channel; a channel decoding unit to convert the digital broadcasting signal received from the tuner unit into a digital signal and to produce an MPEG-2 transmission stream therefrom; a decoding unit to demultiplex the MPEG-2 transmission stream to extract video data and audio data and H.264-decode the video data; and a control unit to decode the extracted audio data using bit-sliced arithmetic coding (BSAC) software and to control the decoded audio data and the video data to be output.

Abstract: An embedded device and an initialization method of the same in which a data loss warning and a reset mode selection menu is displayed, in response to a hard reset command to allow a user to confirm and/or select either cold booting or warm booting after being notified of data loss.

Abstract: A mobile device having a power control function. The mobile device having the power control function includes a plurality of function modules, a control unit, incorporating a predetermined program for driving the plurality of function modules, for driving each of the plurality of function modules by the program corresponding to a control signal; a power control unit for receiving information on the program that is driven by the control unit and selectively supplying the power to each of the plurality of function modules based on the information. In accordance with the present mobile device, when driving a function module and a program provided in the mobile device, only the necessary function modules are supplied with power, thereby reducing unnecessary power consumption and extending the operation duration of the mobile devices such as PDAs, cellular phones, and notebook computers.

Abstract: A data backup method and a data backup apparatus in which a part of a user data area in a volatile memory, wherein data is lost when the power is turned off, is predesignated as a backup area and data is rapidly backed up in an emergency. The data backup method includes the operations of: receiving a command related to data backup through a user interface; obtaining a backup area which is a continuous space of a desired size by adjusting backup priorities between pieces of backup object data when the backup area is to be adjusted in order to execute the command; moving and storing data of the obtained backup area to a non-volatile memory according to a predetermined condition. Accordingly, the user data backup can be rapidly and automatically executed to prevent permanent loss of a database, document file, and the like.

Abstract: A personal hand held terminal has a data sync driver, a USB mass storage driver, and a control section. The control section loads the preset USB mass storage driver or a data sync driver in response to an input command or a request received from a USB host. For example, a system/USB mass storage switchover command is input through a system switchover command key. The control section transmits/receives data to/from the USB host via the USB mass storage driver, if a data transmission/reception request is received from the USB host based on a USB mass storage specification via a USB client interface of the hand held terminal. If the USB host is not provided with a data sync module, it is possible to interface information between both systems, because USB host systems provided with a USB host interface can recognize the personal hand held terminal as a USB mass storage.
