    摘要: Four techniques which result in the visual improvement (Fig. 7) of transitions (510) between video streams with a same packet identifier (PID). The first technique includes two methods: a method for pre-conditioning video stream data for storage on disks (501-504); and a method for transitioning between video streams which utilizes the pre-conditioning. The second technique involves a method for transitioning between video streams where timing information in the new stream is modified so as to be consistent with timing information in the old stream. The third technique involves a method for transitioning between video streams where packets in the old stream are replaced by picture repeat packets. The fourth technique involves a method for transitioning between video streams where packets in the old stream are replaced by null packets.

    摘要: In a parallel processing computer (100) containing a plurality of processors (106n, 108n, 110n), each connected to a memory unit (112n, 114n, 116n), a method and apparatus for accessing a distributed data buffer. Each of the processors within the computer executes a first routine for processing input data to generate output data. During processing, some or all of the data associated with the processing is temporarily stored within a predefined portion of each of the memory units that form a portion of the distributed data buffer. Upon occurrence of an interrupt signal, execution of the first routine is halted. Also, the status of the computer at the time the interrupt signal occured is stored in memory. Thereafter, a second routine (an interrupt routine) is executed to access the data stored in the data buffer. Once the data is accessed, the status of the computer is restored in accordance with the previously stored computer status information. Lastly, the first stored routine is restarted at a position therein at which the first routine was interrupted to execute the second routine.

    摘要: A method and apparatus for recovering data from a failed disk drive in a disk drive array. The method and apparatus includes storing data on an array of disk drives by dividing extents (406) of data into data segments and defining a parity group (404) including at least one data segment from a plurality of data segments (402) from different extents. Parity segments (410) are generated from the data segments in the parity group and stored in the parity group. Furthermore, a second parity segment (408) is generated from the parity segments and stored with the parity group. The method and apparatus then outputs data in realtime to users in a normal disk access mode from parity groups without the failed disk drive, and outputs recovered data in realtime to users in a normal disk access mode from parity groups without the failed disk drive, and outputs recovered data in realtime to the users in a parity correction mode from the parity group containing the failed disk drive.
