Abstract: Disclosed is a user interface method for switching modes in a combined terrestrial DMB terminal. When an event according to other mode (B) occurs, a user's key input is confirmed. It is checked if the key input aims at mode switching, and if so, a current service mode is switched to the other mode (B). Otherwise, it is further checked if the key input is a key input for immediate execution. When the key input for immediate execution aims at immediate execution following audio termination, an audio service in the current service mode (A) is terminated, and then the current service mode is switched to the other mode (B). When the key input for immediate execution aims at immediate execution without the audio termination, a video service in the current service mode (A) is terminated, and then the current service mode is switched to the other mode (B).

Abstract: Disclosed is a wide-band dispersion controlled optical fiber. The optical fiber enables the use of optical signals in various wavelength regions in a wavelength division multiplexing mode communication network by controlling the position of the zero dispersion wavelength, and enables long distance transmission by controlling dispersion slope and bending loss. Furthermore, there is an advantage in that the optical fiber enables not only short distance transmission but also middle/long distance transmission using a single type of optical fiber because the optical fiber is controlled to have negative dispersion values in the O-band wavelength region and positive dispersion values with small deviations in the C-band and L-band wavelength regions.

Abstract: A dual mode Digital Multimedia Broadcasting (DMB) terminal for simultaneously receiving signals of satellite and terrestrial DMB broadcasting stations includes a satellite DMB receiver for receiving and demodulating the satellite signals, and outputting a satellite MPEG 2-TS, and another receiver for analogously processing terrestrial signals. A classification unit switches the two types of MPEG 2-TSs, and outputs the switched MPEG 2-TS to a broadcasting information display unit or an MPEG 2-TS output unit. The first unit generates TAG information, and inserts it into the MPEG 2-TS. A storage unit saves the MPEG 2-TS. The MPEG 2-TS output unit decodes and outputs the MPEG 2-TS. A controller transfers selection information for a switching operation of the DMB classification unit, and transfers information on a decoding scheme.
