A multiplexed display apparatus and method for a digital broadcast receiver are provided. A multi-screen display apparatus for a digital broadcast receiver of the present invention includes a broadcast reception unit for receiving broadcast data of a primary service channel and at least one secondary service channel; a decoding unit comprising a video decoder for decoding video data of all types of video frame of the primary service channel and a predetermined type of video frame of the secondary service channel and an audio decoder for decoding audio data of a predetermined service channel, by time frame; a multiplexed screen processing unit for multiplexing the video data of the primary service channel and the at least one secondary service channel output by the decoding unit; a display unit for displaying the multiplexed video data in the form of multiplexed screen image; and a speaker unit for outputting the decoded audio data in the form of an audible sound wave.

Multi-screen display apparatus and method for digital broadcast receiver

A method and system for displaying digital broadcast signals are disclosed. The method displays a broadcast signal, transmitted from a portable terminal having a digital broadcast receiver, on an external device having a decoding unit. When the external device transmits a digital broadcast playback request and selected channel information, the portable terminal controls the digital broadcast receiver to select a broadcast channel according to the selected channel information, demultiplexes a broadcast signal of the selected broadcast channel, and transmits the demodulated broadcast signal. The external device classifies the demodulated broadcast signal as audio, video, and broadcast information, decodes the classified signals and plays them back. When a communication event is generated while the portable terminal demodulates and transmits the broadcast signals of the selected broadcast channel, the communication event is transmitted to the external device and a wireless communication route is established to process the communication event.

Method and system for displaying digital broadcast data

A fast channel switching method and apparatus for a digital broadcast receiver having a single tuner are disclosed. The fast channel switching method includes setting an ongoing service channel and at least one standby service channel, buffering broadcast data received through the ongoing and standby service channels, outputting the buffered broadcast data of the ongoing service channel, determining whether the ongoing service channel is switched to one of the standby service channels, outputting, if the ongoing service channel is switched to one of the standby service channels, the buffered broadcast data of the switched standby service channel and resetting the ongoing and standby service channels.

Fast channel switching method and apparatus for digital broadcast receiver

A file execution method and system for a portable device for expediting an execution of files is provided. A method for executing an audio file including at least one track associated with a cover image includes displaying a first cover image associated with a track that is playing and displaying a first track list on the first cover image in response to a first key input signal, the first track list listing tracks associated with the first cover image. The portable device implemented with the file execution method and system of the present invention enables a track list to be displayed together with a cover image shared by a set of tracks listed on the track list, thereby expediting execution of files.

File execution method and system for a portable device

An apparatus and method is provided for idle mode screen image presentation device, such as a mobile phone. The screen image presentation apparatus includes a memory for storing a character house including variable and selectable background and function items for executing functions of the mobile phone, a controller for presenting the character house in a given mode, such as an idle mode of the mobile phone, and providing information, when one of the function items is selected, on a function represented by the selected function item, and a display which displays the character house and contents under the control of the controller.

Screen image presentation apparatus and method for mobile phone

A method and apparatus for changing a broadcasting channel list provided in a digital broadcasting service by a user are provided. The method of providing a channel list of digital broadcasting in a mobile terminal includes providing a setting screen of the channel list according to a request for setting the channel list; receiving a digital broadcasting channel selected by a user in the channel list; allocating a predetermined sky wave broadcasting channel number to a virtual channel of the selected digital broadcasting channel according to the user's request; and completing setting of a channel list including the allocated virtual channel information.

Apparatus and method for providing channel list of digital broadcasting in mobile terminal

A band brake apparatus functions to brake a rotary drum, wherein the magnitude of the braking force is independent of the direction in which the drum rotates. The band brake apparatus comprises first and second brake bands situated next to one another and encircling a reversible rotary drum. Each band has an anchored end anchored to a casing, and a displaceable end. The displaceable ends of both bands are connected to a common actuating lever. One band encircles the drum clockwise from its displaceable end, whereas the other end encircles the drum counterclockwise from its displaceable end. Each band includes a hole through which an end of the band extends, in order to form a loop encircling the drum.
