摘要： Provided is a method of efficiently processing a Short-Term Key Message (STKM) in the mobile broadcast supporting the mobile terminal. A structure of a response message according to processing the STKM in the smart card is also provided. In particular, a variety of information necessary for reproducing in the player is included in the response message and delivered to the mobile terminal, thereby the mobile terminal can easily obtain the desired information through the response message. Therefore, when the STKM is processed in the mobile terminal, there is no need to process operations except for a resending check, and the information does not need to be stored separately.

摘要： 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).

摘要： 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.
