Abstract: A transmitter includes a human body communication unit to detect an available broadcast channel; a channel setting unit to set the available broadcast channel to be connected; a broadcast data processing unit to generate a broadcast signal to be transmitted via the human body communication unit. A receiver includes a human body communication unit to receive broadcast signal; a channel setting unit to retrieve the broadcast channel to be connected; a broadcast processing unit to control the human body communication unit to receive the broadcast signal; and a broadcast data processing unit to generate broadcast data. A method for transmitting a broadcast signal includes detecting and setting the available broadcast channel to be connected; generating the broadcast signal; and broadcasting the broadcast signal via the broadcast channel. A method for receiving broadcast signal includes receiving, retrieving, and setting the broadcast channel; receiving the broadcast signal; and generating broadcast data.

Abstract: A mobile terminal includes: a first camera; a second camera; an image processor to process first image data generated by the first camera according to an interface format of a host processor; and a concurrent driver to process second image data generated by the second camera according to an output format of the image processor and to buffer the processed second image data to the host processor. A method for image processing of a mobile terminal includes, if both the first and second cameras operate in an ON state, the image processor processing the first image data of the first camera according to the interface format of the host processor, and the concurrent driver operating in an active mode to process the second image data of the second camera according to the output format of the image processor and buffering the arranged images to the host processor.

Abstract: The present invention provides an interface device using a function of switch that can execute various applications in a mobile terminal by multi-switching USB_D+ and USB_D?, or RS232C data line to an external interface; and, particularly, that can make the mobile terminal used as a PC camera. A universal serial bus (USB) interface device using function of switch includes a dual interface unit for multi-switching data according to a microcontroller unit (MCU) selection signal and a digital signal processor (DSP) selection signal; an image processing unit for digitalizing the image data; a signal processing unit for activating the MCU selection signal or the DSP selection signal, and processing the data; and a memory unit for saving the data according to control of the image processing unit or the signal processing unit.
