摘要： In a data processing system, a first processor pre-allocates data blocks for use in a file system at a later time when a second processor needs data blocks for extending the file system. The second processor selectively maps the logical addresses of the pre-allocated blocks so that when the pre-allocated blocks are used in the file system, the layout of the file system on disk is improved to avoid block scatter and enhance I/O performance. The selected mapping can be done at a program layer between a conventional file system manager and a conventional logical volume layer so that there is no need to modify the data block mapping mechanism of the file system manager or the logical volume layer. The data blocks can be pre-allocated adaptively in accordance with the allocation history of the file system.

摘要： A system for producing multiple concurrent real-time video streams from stored MPEG video clips includes a video server and at least one MPEG decoder array. The decoder array has multiple decoder pairs, each pair having a video switch for switching from one decoder in the pair to the other at a specified time. Switching may occur from a specified Out-point frame to a specified In-point frame, and the specified frames can be any frame type at any location in the group of pictures (GOP) structure. In a preferred construction, the video server has a controller server linked to a series of data mover computers, each controlling one or more respective decoder arrays. The data mover computers use a control protocol to control the decoder arrays, and each decoder uses a data protocol to request data from a respective data mover computer.

摘要： A network file server has storage for storing a file system, and a computer programmed for access to the file system in accordance with a file access protocol and in accordance with a storage access protocol. The computer receives a file access request from a network client for access to a file in the file system in accordance with the network file access protocol. The computer decides whether it should finish the file access using the file access protocol or the client should finish the file access using the storage access protocol. Upon deciding that the client should finish the file access using the storage access protocol, the computer returns to the client metadata of the file including metadata specifying addresses of logical blocks of storage allocated to the file, and then the computer responds to storage access requests from the client by performing read-write access to the file.

摘要： The (run, level) pairs in an original series are inspected to determine whether or not modification of the (run, level) pairs would produce a desirable decrease in a number of bits required for variable-length encoding of the series of (run, level) pairs, despite introduction of noise. If so, the (run, level) pairs are modified prior to variable-length encoding. For example, a (run, level) pair of (M, N) is modified by substitution of a first (run, level) pair of (M−1, 1) immediately followed by a second (run, level) pair of (0, N). A lookup table or testing of predetermined ranges of run length and level magnitude provides a fast determination of whether or not to modify a (run, level) pair. The decoder can be programmed to reduce the noise introduced by this process by recognizing and rejecting (run, level) pairs that are likely to have been inserted during the encoding process.

摘要： Original-quality MPEG coded video is processed to produce reduced-quality MPEG coded video at a reduced bit rate. The processing is based on a scale factor between average frame size of the original-quality MPEG coded video and a desired average frame size of the reduced-quality MPEG coded video. For each Discrete Cosine Transform (DCT) block of each frame, the processing calculates a size of the block of the reduced frame by scaling the original block size by the scale factor, and removes a sufficient number of bits from the original block to obtain substantially the calculated size. In addition, the processing accumulates excess bits when the block size reduction eliminates more bits from a block than are necessary for the desired reduction of the size of the block, and any excess bits are used for processing a number of following blocks.

摘要： Read-only and read-write snapshot copies of a production file in a Unix-based file system are organized as a version set of file inodes and shared file blocks. Version pointers and branch pointers link the inodes. Initially the production file can have all its blocks preallocated or it can be a sparse file having only an inode and its last data block. A protocol is provided for creating read-only and read-write snapshots, deleting snapshots, restoring the production file with a specified snapshot, refreshing a specified snapshot, and naming the snapshots. Block pointers are marked with a flag indicating whether or not the pointed-to block is owned by the parent inode. A non-owner marking is inherited by all of the block's descendants. The block ownership controls the copying of indirect blocks when writing to the production file, and also controls deallocation and passing of blocks when deleting a read-only snapshot.

摘要： Original-quality MPEG coded video is processed to produce reduced-quality MPEG coded video for trick mode operation by removing non-zero AC DCT coefficients from the 8×8 blocks of I-frames of the MPEG coded video to produce I-frames of reduced-quality MPEG coded video, and inserting freeze frames in the reduced-quality MPEG coded video. Preferably, the coded video is stored in a main file, a fast-forward file and a fast-reverse file. The fast forward file and the fast reverse files contain reduced-quality I frames corresponding to original-quality I frames in the main file. A reading of the main file produces an MPEG transport stream for an audio-visual presentation at a normal rate, a reading of the fast-forward file produces an MPEG transport stream of the audio-visual presentation in a forward direction at a fast rate, and a reading of the fast-reverse file produces an MPEG transport stream of the audio-visual presentation in a reverse direction at a fast rate. Preferably, the files share a volume that includes at least one GOP index associating the corresponding I frames of the files.

摘要： To reduce bandwidth of non-scalable MPEG-2 coded video, certain non-zero AC DCT coefficients for the 8×8 blocks are removed from the MPEG-2 coded video. In one implementation, high-frequency AC DCT coefficients are removed at the end of the coefficient scan order. This method requires the least computation and is most desirable if the reduced-bandwidth video is to be spatially sub-sampled. In another implementation, the smallest-magnitude AC DCT coefficients are removed. This method may produce an undesirable increase in the frequency of occurrence of escape sequences in the (run, level) coding. This frequency can be reduced by retaining certain non-zero AC DCT coefficients that are not the largest magnitude coefficients, and by increasing a quantization scale to reduce the coefficient levels. The reduced-bandwidth video can be used for a variety of applications, such as browsing for search and play-list generation, bit stream scaling for splicing, and bit-rate adjustment for services with limited resources and for multiplexing of transport streams.

摘要： A processing device of an information processing system is configured to identify different candidate clouds for performing a processing job for a requesting user, to collect respective sets of parameters from the different candidate clouds with each such set of parameters characterizing at least one aspect of a manner in which the processing job would be performed in the corresponding candidate cloud, and to compile information characterizing the collected sets of parameters so as to permit informed selection by the requesting user or another system entity of at least a particular one of the candidate clouds for performing the processing job. The processing device may be further configured to permit the requesting user to monitor and/or control the processing job as it is executing in the selected cloud(s). For example, warnings may be provided to the user if execution of the processing job is not meeting specified user requirements.
