Abstract: A mobile terminal may be remote controlled by setting a condition for the mobile terminal to enter a remote-control mode, receiving a call connection request, and entering the remote-control mode when the call connection request is received at the mobile terminal and the call connection request corresponds to the set condition. A function control signal may be received by the mobile terminal while the mobile terminal is in the entered remote-control mode, and a remote-control function may be performed that corresponds to the received function control signal.

Abstract: A communication method and data transmission protocol adapted to an image communication apparatus is provided. More particularly, this protocol provides a structure in which video, audio, and control data are multiplexed for communication, wherein loss of data other than video and audio data can be minimized, video, audio, and control data can be easily separated when the receiver side reads a packet data, and its control data can be set so as to select an image quality and a retransmission privacy mode.

Abstract: In an interface apparatus and a method thereof for a display system displaying an image (an animation, a still image and a text) and a text through an I2C (IIC) interface of a main CPU without operating a video codec in a standby mode of a display system, the apparatus includes a main CPU for outputting data including an image and a text according to an operation mode of a system, a video codec being inputted the data and outputting the data by interfacing with the main CPU according to the operation mode and a LCD driver being inputted the data through the video codec in accordance with the operation mode or being inputted the data from the main CPU through the I2C interface of the main CPU and displaying the inputted image and text on the screen.

Abstract: A data transmission protocol for reducing the MODEM connection time in an image communication is provided by the structure of a flag for informing of a start of a file, header information for discriminating a nature of data information, flag data address information which contains address information corresponding to flag data of the data information, data information, and a flag for informing of a completion of the file.

Abstract: A rotary transformer circuit, for a video cassette recorder, including: a single rotary transformer; a plurality of magnetic heads for recording/playing back signals on the magnetic tape; and a switching circuit for selectively sampling each of the plurality of magnetic heads and for forming a signal of concatenated individual-head sub-signals and for selectively connecting a signal of concatenated individual-head sub-signals to corresponding ones of the plurality of magnetic heads. The switching circuit transferring the signal of concatenated individual-head sub-signals through the single rotary transformer. The circuit avoids noise caused by cross-talk when using multiple rotary transformers.
