Abstract: An apparatus and method for dynamic ciphering in a mobile communication system are provided. In a dynamic ciphering mobile communication system, a ciphering apparatus receives the Security Code Table (SCT) in advance and stores it, creates dynamic cipher keys when the data need to be ciphered using the SCT and the frame number of the data, and transmits the frame containing the data ciphered by the created dynamic cipher key, a deciphering apparatus receives the frame, creates the dynamic cipher key using the SCT and the frame number of the received frame, and deciphers the data contained in the frame using the dynamic cipher key created, and an authentication center manages authentication keys which are subscribers' authentication information, and creates and manages the SCTs of subscribers.

Abstract: A CD video-song accompaniment apparatus reproduces information from a compact disc and contains a CD reproducing portion, a CD-OK reproducing portion, and audio selector, and a main controller. The CD reproducing portion reads audio data from the compact disc and generates an audio signal if the compact disc is a first type of compact disc. On the other hand, the CD reproducing portion reads digital data from the compact disc if the compact disc is a second type of compact disc. The CD-OK reproducing portion inputs the digital data, which contains background image data and music information data, generates a first background image and a second background image based on the background image data, and generates a CD-OK audio signal based on the music information data. The audio selector inputs the audio signal generated by the CD reproducing portion and the CD-OK audio signal generated by the CD-OK reproducing portion and selectively outputs either the audio signal or the CD-OK audio signal.

Abstract: A song program and a motion picture background image suitable for the mood of the song program are recorded on a recording medium. A video-song accompaniment apparatus employs the recording medium to reproduce the song program and the motion picture background image. The recording medium has a lead-in area, a program area and a lead-out area.

Abstract: An external sync image superimposing apparatus synchronizing an analog video signal with digital image data is provided by an apparatus which includes a sync separator for separating an external composite sync signal from an external composite image signal, a clock signal generator for synchronizing the frequency of the clock signal with an external sync signal according to a phase difference between the horizontal sync signal of the separated external composite sync signal and the internal horizontal sync signal and generating the adjusted clock signal, a sync signal generator receiving the adjusted clock signal for generating an internal composite sync signal and a reproduction address signal, a video memory for reading stored digital video information according to the reproduction address signal and a superimposing circuit for converting the digital video information from the video memory into an RGB signal, encoding the internal composite sync signal and the RGB signal as a color television signal, and su

Abstract: A disk recording medium includes a lead-in area, a program area and a lead-out area. The program area includes: a first track on which a plurality of data signals each of which has a different index from the others is loaded; a second track on which a plurality of programs is loaded, whereby the plurality of programs consists of the sequential combination of the indices of at least one data signal among the plurality of data signals and each program has a different index from the others; a third track on which a data index table comprising the indices of the respective data signals and initial address information is loaded; and a fourth track on which a program index table comprising the indices of the respective programs and initial address information is loaded.

Abstract: A disk recording medium includes a lead-in area, a program area and a lead-out area. More specifically, the program area includes a first track on which a plurality of data signals, each of which has a different index from all of the others, is loaded, a second track on which a plurality of programs are loaded, a third track on which a data index table including the indices of the respective data signals and initial address information are loaded, and a fourth track on which a program index table including the indices of the respective programs and initial address information are loaded. The lead-in area is loaded with a table of contents consisting of the initial address information and a plurality of pointers, each of which is different from all of the others each of which designates the respective tracks of the program area and the initial position of the lead-out area.
