    摘要： Disk players for allocating pointers to the respective frames of CD data and storing the pointers in a memory, and methods of processing reproduced data of the disk player are provided. According to one aspect, a disk player includes a pointer controller, which allocates pointers to frames of recorded data read from a disk, wherein the allocation of the pointers starts from a first frame following frames having special sub-code synchronization signals and is performed in a predetermined order; a memory, which stores the frames and the allocated pointers; and a memory controller, which controls an operation of writing the data to memory. A pointer is allocated to every frame of the recorded data reproduced from the disk player, and the allocated pointers and the frame data are stored in the memory. The pointers are retrieved and the respective frame data stored in the memory are output. Therefore, the sound continuity can be maintained even in a vibration environment causing jitter.

According to one aspect, a disk player includes a pointer controller, which allocates pointers to frames of recorded data read from a disk, wherein the allocation of the pointers starts from a next frame after frames having sub-code synchronization signals and is performed in a predetermined order; a memory, which stores the frames and the allocated pointers; and a memory controller, which controls an operation of writing the data to memory.

    摘要： CIRC code decoding includes for each input frame a one-symbol delay operation of every second data symbol and the inversion of parity symbols, C1 word decoding, de-interleaving, C2 word decoding, and a two-symbol delay op-eration before output. The error correction capabilities can be improved if the C1 word decoding, de-interleaving and C2 word decoding are carried out twice (double pass operation) before the two-symbol delay operation and out-put. The invention allows double pass operation as well as sin-gle pass operation and uses a single memory with minimum capacity, wherein to three parts of the memory specific operations are assigned and wherein the memory is con-trolled in a special way.

    摘要翻译： 对于每个输入帧，CIRC码解码包括每个第二数据符号的单符号延迟操作和奇偶校验符号的反转，C1字解码，解交织，C2字解码和输出之前的两符号延迟操作。 如果在双符号延迟操作和输出之前执行C1字解码，解交织和C2字解码两次（双通操作），则可以提高纠错能力。 本发明允许双程操作和单通过操作，并且使用具有最小容量的单个存储器，其中分配存储器特定操作的三个部分，并且其中存储器以特殊方式被控制。

    摘要： A motion picture film having digital audio data recorded in at least one sound track thereof. Such digital audio data includes a plurality of bytes of data each having 8 bits of data. Each respective bit of each byte of audio data is recorded in a sound track of the film in the film running direction and each byte is arranged side-by-side in a direction normal to the film running direction to form a compression processing block. C1 parity data is added to each such compression processing block and C2 parity data is added after a predetermined interval of plural compression processing blocks. Error correction may be performed by utilizing the C1 and C2 parity data for each compression processing block and at the predetermined interval of plural compression blocks.
