Abstract: A method and an apparatus are provided in which wireless communication is performed through a mobile network. User selection of a hot key enables automatic synchronization of data in a mobile terminal with a web server upon entry into a wireless local area network (LAN) service area. A user ID and password are transmitted to the web server for. A type of data is set to be automatically transmitted based on a user selection. Upon the mobile terminal entering the wireless LAN service area and connecting to the web server, the data is automatically transmitted to the web server. The transmission of the data is stopped and a warning message is displayed, upon the mobile terminal exiting the wireless LAN service area. Upon the mobile terminal re-entering the wireless LAN service area, transmission of the data is automatically resumed from a point where the transmission was stopped, without reauthentication.

Abstract: Disclosed is a surveillance apparatus such as a surveillance camera and a digital video recorder. The surveillance apparatus includes: an analog-to-digital converter configured to convert an analog video signal, of at least one image of a region captured by an optical system, into digital video data of the region; and a main controller configured to detect a current motion region from the digital video data of the region, remove a high frequency component of the region except the current motion region, and transmit the digital video data of the region, from which the high frequency component is removed, to a target device over a communication network.

Abstract: Provided are a system, mobile terminal, and method for storing data into a web storage using a wireless LAN service. The method includes setting synchronization of the mobile terminal and a web server providing a web storage service; setting data of the mobile terminal to be stored into a web storage provided by the web server; sensing whether the mobile terminal enters a wireless LAN service area; connecting, if it is sensed that the mobile terminal enters a wireless LAN service area, the mobile terminal to the web server; and transmitting the set mobile terminal data to the web server.

Abstract: Disclosed herein are a method and a system for a zapping advertisement service, and more particularly, a method and a system for providing various kinds of advertisement services targeted to a content recipient to an advertiser wanting a zapping advertisement and effectively exposing the zapping advertisement to the content recipient. Accordingly, an embodiment of the present invention provides additional information corresponding to the zapping advertisement according to a user request when the zapping advertisement is provided for zapping time generated at the time of switching a channel and maximizing an advertisement effect for the zapping time by repeatedly providing corresponding zapping advertisements, or continuously providing the zapping advertisement associated therewith at the time of switching the screen.

Abstract: A television screen control apparatus includes a broadcasting contents data processing unit receiving broadcasting content for a new channel in response to an channel changing input signal. When broadcasting content is not displayed during a channel transition period, advertising information on a background plane is visible to a viewer.

Abstract: A servo track writing method and a servo track write system of a hard disk drive (HDD) using the servo track write method. The servo track writing method includes performing a reference check (R/C) on a first servo pattern which is pre-written on a first surface of a disk, and if the R/C determines that a quality of the first servo pattern is not good, erasing a specific area of the first servo pattern and writing a second servo pattern on a second surface of the disk. Therefore, process time delay factors of a series of rework processes of writing servo patterns on a disk are removed to shorten a process time of the rework processes. In addition, productivity of a HDD is improved.
