Abstract: A broadcast receiver and a method of processing data are disclosed. The broadcast receiver includes a broadcasting module, at least one function module, and a controller. The broadcasting module receives and processes mobile broadcast signal. The function module outputs at least one of a video output and an audio output. The controller controls output of at least one of video output and audio output corresponding to each of the broadcasting module and the function module, when a mode shift occurs between the broadcasting module and at least one the function module.

Abstract: A broadcast receiver, and a method of processing data are disclosed. The broadcast receiver includes a receiving unit, a RS frame decoder, a decoding unit, and an output unit. The receiving unit receives a broadcast signal multiplexed mobile broadcast service data including a first information associated with safety/security and main broadcast service data. The RS frame decoder performs CRC-decoding and RS-decoding on the RS frame, thereby correcting errors occurred in the corresponding mobile broadcast service data. The decoding unit extracts the first information from the error-corrected mobile broadcast service data, thereby decoding the extracted data with at least one of an audio decoder, a video decoder, and a data decoder. The output unit outputs the first information decoded by the decoder in a form of at least one of a text, a voice message, and an image.

Abstract: A broadcast receiver and a method of processing data are disclosed. The broadcast receiver includes a receiving unit, a RS frame decoder, a storage unit, and a navigation unit. The receiving unit receives a broadcast signal multiplexed mobile broadcast service data including information on route prediction and main broadcast service data. The RS frame decoder performs CRC-decoding and RS-decoding on the RS frame, thereby correcting errors occurred in the corresponding mobile broadcast service data. The navigation unit uses the information on route prediction and a current position information of the broadcast receiver, thereby predicting at least one route.

Abstract: A broadcast receiving system capable of receiving mobile broadcast data and a method for processing broadcast signals are disclosed. The broadcast receiving system includes a first receiving unit, a second receiving unit, a known sequence detector, a equalizer, and a display unit. The first receiving unit receives a first broadcast signal including first mobile broadcast service data and first main broadcast service data. The second receiving unit receives a second broadcast signal including second mobile broadcast service data and second main broadcast service data. The known sequence detector detects at least one of known data included in the received first broadcast signal and known data included in the received second broadcast signal. The channel equalizer uses the detected known data, thereby channel-equalizing the received first and second mobile broadcast service data corresponding to the detected known data.

Abstract: A broadcast receiver and a method of processing data are disclosed. The broadcast receiver includes a signal receiving unit, a known sequence detector, and a channel equalizer. The signal receiving unit repeats, when an operating mode of the broadcast receiver has been switched to a Discontinuous Receive (DRx) mode, preset wake-up and sleep sections, and receives a broadcast signal containing main broadcast service and mobile broadcast service data in the wake-up section. The known sequence detector detects known data included in the received broadcast signal. The channel equalizer uses the detected known data, thereby channel-equalizing the received mobile broadcast service data.

Abstract: An A/V equipment and a channel selecting method are disclosed, wherein the A/V equipment forms a wireless network by using information of each channel obtained by scanning each channel of a monitoring channel set to compute a predetermined parameter, and comparing the computed parameters to select an optimum channel. Consequently, the A/V equipment is configured to form a wireless network at a channel in which the wireless environment is the most satisfactory, thereby being enabled to satisfy a QoS requirement and to provide good quality of service, and to effectively distribute frequency resources under an environment, where the wireless equipment is mixed exists.

Abstract: The present invention relates to a method for transmitting/receiving voice packet data having different encoding techniques through one server in a multimedia internet protocol system. According to the present invention, the voice packets having a predetermined size and a predetermined period which are received from a transmitting IP phone in accordance with each encoding technique are sequentially stored, without performing decoding and encoding operations, and the stored voice packets are sequentially transmitted to a receiving IP phone when a transmission demand is transmitted from the receiving IP phone by a predetermined period.
