Abstract: A broadcasting receiving apparatus includes a receiver having a plurality of tuners, a storage configured to store an image received by the receiver and a controller configured to control at least one of the tuners that does not tune to a currently viewed image out of the plurality of tuners, to alternately tune a plurality of channels for preset time, and controls the storage to store a channel information image corresponding to respective channels based on an image tuned to by the at least one tuner.

Abstract: In an image processing apparatus and method, a digital broadcasting receiver enables electronic program guide (EPG) information data and digital broadcasting image data not to visually overlap each other when digital broadcasting image data of a channel, including caption information, is processed. The image processor of the digital broadcasting receiver determines whether a changed channel includes caption information, and when the changed channel includes the caption information, the image processor scales down the digital broadcasting image data received from a digital broadcasting server, displays the scaled down digital broadcasting image data on one side of a screen, and displays EPG information data on another side of the screen.

Abstract: An apparatus and a method for switching channels in a digital broadcasting system. The apparatus and method of the invention can convert an abridged channel name comprised of alphabetic letters, or a combination of alphabetic letters and Arabic numbers, inputted by a user, into a corresponding channel number and switches into a digital broadcasting channel at a tuner according to the channel number so that a user can easily switch broadcast channels.

Abstract: A method of changing between a Data over Cable Service Interface Specifications (DOCSIS) mode and a DOCSIS Set-top box Gateway (DSG) mode in a digital broadcast receiver, includes: performing channel searching to change into the DSG mode, and detecting a cause of a failure in securing a channel via a database upon failing to secure the channel in response to a user requesting a change of mode via a host; and recovering the DSG mode as a result of detecting the failure cause upon receiving DSG data. It is therefore possible to change from the DOCSIS mode to the DSG mode according to the state of the OpenCable digital broadcast receiver, thereby improving its capability of coping with a field.

Abstract: An apparatus and method of managing a reception state of data in a digital broadcasting system has monitoring functions of a cable network, a broadcasting channel and received data realized for a set-top box as a digital broadcasting receiver of the digital broadcasting system, and a notification message depending on generated reception error of the data is transmitted to a head end, thereby efficiently managing data transmission of the cable network, the broadcasting channel and each server of the head end.

Abstract: A system adapted to process data required by a bi-directional application in real-time in a digital data broadcasting based on the cable network includes: a data server adapted to collect data needed for data broadcasting and to transmit the data; a broadcasting station adapted to transmit an application including information on the data server; and a set-top box adapted to couple the application received from the broadcasting station to the data received from the data server in accordance with the information on the data server.

Abstract: A time information management method and system for providing time information necessary for an embedded system, without using a hardware real-time clock device. The method and system comprises accessing a time server providing real-time information through the Internet during system initialization; acquiring the real-time information from the time server through a message exchange with the time server; and defining the acquired real-time information as the system's time information and updating the time information depending on a timer operation of the real-time operating system.
