IPC: H03M7/40
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a certain propagation control capability and to realize an excellent compression rate in the adaptive data compression system. SOLUTION: It is discriminated whether a block to be compressed is the head of a cluster or not (S1). If it is the head of the cluster, the initial state of a model used for compression is set to a preliminarily determined state (S2) If it is not the head of the cluster, the model is set to the state for the end of compression of the block at the head of this cluster (S3). After the initial state of the model is determined, each block is compressed (S4). The model is successively updated in the process of compression. It is confirmed whether data to be compressed exists yet or not before switching to the next block (S6). If it exists yet, compression of the next block is started (S6); but if it doesn't exist, compression is terminated.

Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To store information preferred by the user by deleting main information with lower priority from a storage means sequentially based on the priority set by the user without increasing the capacity of the storage means. SOLUTION: A broadcast signal for integrated service digital broadcasting to be selected is fed to a signal separate section 50, in which the signal is separated into main information and additional information and fed to a decoding section 52 and a storage means 50.

IPC: G11B7/004
Filed: 1985-10-08
Abstract: PURPOSE:To record and reproduce data at a high transfer rate by giving plural optical heads irradiating a laser beam on an optical disk and simultaneously or individually driving laser diodes in the optical head. CONSTITUTION:Two optical heads A and B can be simultaneously or individually driven, and an external controller controls traces on the track of laser beams and jumping between tracks. For instance, the laser beam of the head A repeats jumping between tracks at every half rotation, whereby the head A traces the track toward the outer periphery from 1 4 5 8 9 12... in this order. The head B tracks the track in the same manner from 2 3 6 7 10 11... in this order. Accordingly, when the optical heads A and B are simultaneously driven at the time of recording, two laser beams simultaneously trace the track while the optical disk makes one turn at a constant rate, whereby this can obtain a recording rate twice a case where a laser beam is individually driven.
