Abstract: An apparatus and a method for reducing channel changing time of a digital broadcasting in a mosaic EPG(Electronic Program Guide) system are provided to display a mosaic EPG image with low resolution during the channel change processing time. When a conversion event to a mosaic EPG mode is generated in order to search a channel(S410), a digital broadcasting receiving system provides a mosaic image on a TV screen. When a user moves a cursor to one of plural sub pictures(S420), the video/audio signals are outputted from the channel corresponding to the sub picture(S430). When a desired channel is discovered, the corresponding channel is selected(S440). Whenever the channel is changed by the cursor, the video/audio signals are outputted.

Abstract: An apparatus and a method for converting a channel in a digital broadcasting system are provided to continuously output a broadcasting program, received through a channel for watching and complete the channel conversion through an additional channel for conversion when channel conversion is requested, and then output a broadcasting program after the channel conversion so that disconnection of broadcasting due to a long channel conversion time in the digital broadcasting system can be prevented. An apparatus for converting a channel in a digital broadcasting system comprises a controller(270). The controller(270) outputs a broadcasting program, received through a channel for watching, to the first window on a display unit, and outputs channel conversion information, received through an information providing channel, to the second window on the display unit. When channel conversion is requested, the controller(270) performs the requested channel conversion through a channel for conversion. When the channel conversion is completed, the controller(270) outputs a broadcasting program, received through the channel for conversion, to the first window.

Abstract: A device and a method for changing a channel in a digital broadcasting system are provided to carry out channel conversion between logic channels without any additional CAS(Conditional Access System) processing, thereby reducing a time required for the channel conversion. A device for channel conversion in a digital broadcasting system includes a tuner(210) for carrying out tuning of a physical channel, and a CAS(Conditional Access System;230) for restraining access to the tuned physical channel. A demultiplxer(240) carries out demultiplexing for the physical channel to distinguish logic channels included in the physical channel. A control part(270) controls the tuner, the CAS, the demultiplexer, and a demodulation part(220) to receive and output the logic channels corresponding to a user's channel conversion request as the request is received.

Abstract: An apparatus and a method for reducing a channel conversion time in digital broadcasting through the prediction of the channel change are provided to display the preference channels on a screen as the OSD(On Screen Display) type. A tuner(110) tunes a desired channel from the received broadcasting channel. A demodulation member(120) demodulates the tuned analog signal into a digital signal and transmits the reception restriction data to a CAS(Conditional Access System)(160). When a subscriber selects a channel, the CAS confirms whether the subscriber has the watching authority related to the corresponding program channel. If there is the watching authority, the encrypted broadcasting data are de-scrambled.
