摘要： A protocol and interface provides continuous play over multiple clips for extended periods of time, allows a play-list to be edited dynamically after being given to the video server and during playback of clips in the play-list, allows some notion of "current time" to be used during the streaming of continuous media data, and supports features of the "Louth Automation" video disk communications protocol. Preferably, the client application first creates a session with a play-list containing a fixed number of entries; the number should be as small as possible consistent with the client's requirements. The client edits this play-list by appending the first few clips and then starts the session playing. Each time transmission of video data of a clip is completed, the clip is removed from the head of the play-list, all other clips are moved down, and a callback is issued to the client with the current, updated, play-list. A callback is also issued with the updated play-list to acknowledge each edit command. Preferably, there is a limit as to how close to air-time a clip normally may be deleted or new material inserted, in order to ensure continuity of transmission of the video stream of each clip. To allow live break-ins or other "emergency" operations, however, the session may be paused and later resumed and subsequent clips may be "trimmed" to reduce their play times to recover the time lost to the break-in.

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： 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： Transform coefficients for blocks of pixels in an original picture are quantized to produce respective sets of quantization indices for the blocks of pixels. The quantization indices for at least some of the blocks are produced by using a quantization step size that is not uniform within each block. Largest magnitude quantization indices are selected from the respective sets of quantization indices for (run, level) encoding to produce the (run, level) encoded picture. For example, MPEG-2 coded video includes a set of non-zero AC discrete cosine transform (DCT) coefficients for 8×8 blocks of pixels. For scaling the MPEG-2 coded video, non-zero AC DCT coefficients are removed from the MPEG-2 coded video to produce reduced-quality MPEG-2 coded video that includes no more than a selected number of largest magnitude quantization indices for the non-zero AC DCT coefficients for each 8×8 block.

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： 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.
摘要翻译：为了减少不可扩展的MPEG-2编码视频的带宽，从MPEG-2编码视频中去除8×8块的某些非零AC DCT系数。在一个实现中，在系数扫描顺序结束时去除高频AC DCT系数。该方法需要最少的计算，并且如果减小带宽视频要在空间上被次采样，则是最希望的。在另一实施方式中，去除最小量级的AC DCT系数。该方法可能在（运行，级别）编码中产生转义序列的发生频率的不期望的增加。可以通过保持不是最大幅度系数的某些非零AC DCT系数，并且通过增加量化尺度来降低系数水平，可以减小该频率。缩小带宽视频可以用于各种应用，例如用于搜索和播放列表生成的浏览，用于拼接的比特流缩放以及用于有限资源的服务的比特率调整和用于传输流的复用。

摘要： Mirrored data is contained in a first data storage device array and also in a second data storage device array. However, devices in the first array are not simply mirrors of devices in the second array. Instead, each data storage device in the second array contains a respective share of the mirrored data contained in each data storage device in the first array, and each data storage device in the first array contains a respective share of the mirrored data contained in each data storage device in the second array. Therefore, when a data storage device in one array fails, the failure load is spread over the data storage devices of the other array. For disk storage devices, the mirrored data can be arranged in the first and second arrays so that the mirrored data is contained at the same disk track radius in both arrays in order to equalize seek time for write access or sequential read access to both arrays. Alternatively, the mirrored data can be arranged so that mirrored data at the minimum and maximum track radius in one array is contained at the mean track radius of the other array in order to minimize seek time for random read access.
