Abstract:
PURPOSE: A terminal and a method for enabling the terminal to receive a frame are provided to selectively receive a necessary frame from frames including broadcasting data. CONSTITUTION: A control unit determines whether broadcasting data is received through the first RS(Read-Solomon) frame for transmitting video broadcasting data or whether broadcasting data is received through the second frame for transmitting audio broadcasting data. In case of broadcasting data received through the second RS frame, the control unit checks a channel state. If the checked channel state is more than the preset first channel state, the control unit receives only the broadcasting data in the second RS frame(905).

PURPOSE: A portable terminal performing a mobile broadcasting function and a channel control method of the same are provided to display a broadcasting data of a primarily searched channel and updates channel information of other channels, thereby reducing the channel searching time, which a user feels, when displaying channel information. CONSTITUTION: A control unit(230) checks standby interval, which frame is not received, through channel information of received frame and outputs broadcast data included in the frame. The control unit scans the frequency by controlling a broadcasting receiving unit(210) in the checked standby interval. The control unit analyzes a frame received per scanned frequency and checks the channel information. A storing unit(250) updates the checked channel information per frequency, and stored the information.

Abstract:
A method and an apparatus for receiving broadcast data in a digital broadcast receiver are provided to decode the data correctly in spite of the broadcast data error or the bad receiving condition, and to reduce the standby power consumption. A point of time for starting the power-off mode is inspected in case of finishing the burst section. The receiving environment for receiving the broadcast data from the transmitter is inspected in case of the power-off mode section. In case of the good receiving environment, the critical value of the section interval is stored in the received burst section. In case of detecting the new first section, the section number of the detected first section and the detected time are stored. In case of detecting the second section, the difference of the clock number between the first section and the second section is calculated. The effectiveness of the calculated clock number difference is inspected. In case of existing the effectiveness, the number of the rest section is confirmed. The frame boundary expectation position is calculated by using the number of the rest section and the clock number difference. The time slicing is performed to the frame boundary expectation position.

A transmitting unit(130) multiplexes the encoded video streams and transmits the multiplexed video stream through a broadcasting channel. The transmitting unit(130) transmits information about the number of the video streams transmitted through the broadcasting channel as system information.
