Abstract: A data transmission system for minimizing the number of errors during Tx/Rx times of mobile service data under mobile environments, and a data processing method for the same are disclosed. The system additionally codes the mobile service data, and transmits the resultant coded mobile service data. As a result, the mobile service data has a strong resistance to noise and channel variation, and can quickly cope with the rapid channel variation.

Abstract: An optical detector is provided. The optical detector allows an auto-convergence control to be effectively made by cutting off external light incident to an optical sensor for use in the auto-convergence of a projection TV. The optical detector includes optical sensors and external light cut-off units. The optical sensors are positioned in an inside of the projection TV to receive test signals. The external light cut-off units are protruded to a direction to which the test signals are incident.

Abstract: A method of manufacturing a solvent-soluble stamp for nano-imprint lithography is provided. According to the method, a stamp is formed on a master substrate made of an ultraviolet-transparent material, using a material which is soluble in a solvent, and then a metal stamp or another stamp for a nano-imprint lithography is manufactured using the solvent-soluble stamp. Next, the stamp for nano-imprint lithography can be achieved by melting the soluble stamp. Therefore, it is possible to reuse the master several times. Further, it is possible to solve a problem in which a mold cannot be separated from the stamp. Furthermore, a uniform and clean stamp with a nano size can be obtained.

Abstract: A receiver and receiver control method facilitate user access to recorded content, including access for viewing, editing, and deletion, by providing means for improved file recognition so that recording items can be accurately and efficiently confirmed via a main screen without playing back any of the recording items in full. The method uses a recording list including at least one window, at least one progress bar, and additional information such as a program title and enables the recording list to be constructed from a received stream.

Abstract: Provided are a system and a method for diagnosing and editing a channel using received signal sensitivity. The method allows a user to edit a channel on a received signal sensitivity diagnosis screen of a digital TV, so that the user can edit a favorite channel while checking received signal sensitivity of a predetermined channel. Since a user can edit a channel while checking received signal sensitivity of each channel, channel diagnosis and channel editing can be performed accurately and efficiently.

Abstract: An over-the-air transceiving method and a mobile receiver using the same minimize the time for downloading driver software configured as a plurality of download data blocks (DDBs) and achieves timely downloads of driver software despite failures in receiving one or more download data blocks. On the transmitter side, the method includes steps of transmitting first DDB data corresponding to the plurality of download data blocks, each download data block of the first DDB data having a first packet identifier value; and transmitting second DDB data corresponding to the plurality of download data blocks, each download data block of the second DDB data having a second packet identifier value, the transmission of the second DDB data exhibiting a temporal overlap with respect to the transmission of the first DDB data.

Abstract: A method of controlling an apparatus for receiving an electronic program guide (EPG), and an EPG receiver using the same, enable preferred broadcast programs to be displayed and viewed using a reserved recording function, without performing specific searching or playback operations, by employing a user channel to simulate reception of real-time television broadcasting to enable a sequential display and viewing of at least one broadcast program via the user channel.

Abstract: An apparatus and method for permanently storing a broadcast program during time machine function is disclosed. An apparatus for permanently storing a program during a time machine function comprises a first memory for temporarily storing a plurality of programs, an on screen display (OSD) data generator for displaying OSD data on a screen, an address generator for generating a location information of the stored plurality of programs, a third memory for storing the location information of the stored plurality of the programs, and a controller for retrieving the location information of the program if the program is selected and for permanently storing the program at a second memory.

Abstract: An apparatus and method for simultaneously providing a plurality of time shifting functions is disclosed. An apparatus for simultaneously providing a plurality of time shifting functions comprises a first memory for storing a first broadcast program for performing a first time-shifting function; a second memory for storing a second broadcast program for performing a second time-shifting function; and a controller for selecting and displaying at least one of the first and the second stored broadcast programs. Also, a method for simultaneously providing a plurality of time shifting functions comprises determining if a first time shifting function is used; storing a first broadcast program in a first memory for time shifting function if the first time shifting function is not used; determining if a second time shifting function is used; and storing a second broadcast program for time shifting function in the second memory if the second time shifting function is not used.
