摘要： This invention relates to data input/output apparatus and the like, which are suitable to be applied to an AV server. As nonlinear accessible storage medium, there is provided with HDD array device (13). When a controller (11) of an AV server (10) receives a command for reproducing data from a minimum of two discontinuous areas in the HDD array device (13) in a first order, the HDD array device (13) then puts the command in an order such that a period of time for access is minimal to reads the data so that the read data are rearranged in the first order to be outputted through decoders (15) to (18). Thereby, the efficiency of data transfer is improved without complications.

摘要： When data including video and/or audio data is dispersed into data each having a predetermined unit and recorded in a non-linear accessible recording medium, or reproducing data dispersed and recorded, in case that the status information is not output in a predetermined period, it is decided that an error occurred to perform an error processing. Also, when data including video and/or audio data is dispersed into data each having a predetermined unit and recorded in a non-linear accessible recording medium with a redundancy, in case that an error occurred, which can be corrected within the redundancy, the fault information is recorded and the data is restored immediately by using the redundancy when the data of which an error occurred is reproduced based on the fault information.

摘要： A method and apparatus for delivering multimedia video data from a server (host processor) to a plurality of clients connected to a communications network. More specifically, with this invention, preprocessed video and multimedia data packets are striped across disks in units of fixed playback time, even if such units result in variable length stripes. To deliver multiple video or continuous media streams, the disks in the array are accessed simultaneously so that at any given instance, different disks are accessing the video or multimedia data for different streams. Access to the disks for reading the continuous media files is scheduled periodically, with the period equal to the back time of the stripes. Because each disk read command retrieves data for a fixed play back time, if the first read command for a continuous media stream request can be scheduled to complete on a disk within a playback time, all subsequent read commands are also guaranteed to not interfere with read commands of other streams. Data is delivered directly from the disk array to the communication network by a stream controller without being sent to the host system. Disk storage is utilized efficiently by allocating disk space in units of cylinders and storing the variable size stripes of video in packed format.

摘要翻译： 一种用于将多媒体视频数据从服务器（主处理器）传送到连接到通信网络的多个客户端的方法和装置。 更具体地说，利用本发明，即使这样的单元产生可变长度的条带，预处理的视频和多媒体数据分组以固定的播放时间为单位跨磁盘分条。 为了提供多个视频或连续媒体流，阵列中的磁盘被同时访问，使得在任何给定的实例中，不同的磁盘正在访问用于不同流的视频或多媒体数据。 定期访问用于读取连续媒体文件的磁盘，周期等于条带的后续时间。 因为每个磁盘读取命令检索固定播放时间的数据，如果可以在播放时间内将用于连续媒体流请求的第一读取命令调度为在盘上完成，则所有后续读取命令也被保证不干扰读取 其他流的命令。 数据通过流控制器直接从磁盘阵列传送到通信网络，而不会发送到主机系统。 通过以圆柱体为单位分配磁盘空间并以压缩格式存储可变大小的视频条带来有效地利用磁盘存储。

摘要： A method of scheduling the retrieval of both continuous and non-continuous data retrieves continuous data streams at a predetermined rate. At least one server receives one or more requests for the retrieval of a stream of media data by at least one terminal. Each requested media stream is characterized by a playback rate r i . A common retrieval time period is established for each requested media stream. The common retrieval time period is a function of the playback rate. The retrieval of the requested media stream is scheduled in the order in which each request is received by the server.

摘要： A synchronized data transfer system (200) including storage processor nodes (103), a backbone communication switch 101, multiple titles subdivided into subchunks (113a) - (113e) and distributed across the nodes, a user process (207) executed on a first node (201), a transfer process (215) executed on a second node (203), and a management process (219) executed on a management node (205). The user process sends a timestamped read request to request a corresponding subchunk. The transfer process sends a message to the management process for each received read request, where each message identifies source and destination nodes. The management process broadcasts transmit commands to initiate sequential transmit periods, receives the messages, and selects from among the received messages to ensure that each node sends or receives only one subchunk during each transmit period. The management process sends a transmit request for each selected message, and the transfer process sends a subchunk identified by a transmit request in response to the transmit command.

摘要： When data including image and/or voice data are divided into predetermined units and distributedly recorded on a nonlinear-accessible recording medium or when the distributedly recorded data are reproduced, if status information is not outputted for a predetermined time, it is assumed that an error is produced and error processing is performed. Further, when data including image and/or voice data are divided into predetermined units, given redundancy and distributedly recorded on a nonlinear-accessible recording medium, if an error whose type is within a region that can be corrected by the redundancy is produced, defect information is recorded. When the data including the error are reproduced, the data are immediately restored in accordance with the defect information by utilizing the redundancy.

摘要： In a system (100), such as a video-on-demand-server, a reader (180) reads data from a storage medium (110) and stores the read data in buffers (125). The data is supplied from the buffers (125) to users (130) for consumption in the form of a plurality of data streams. The data streams may be fixed rate or variable rate with an identical maximum consumption rate of Rmax data elements per second. The reader (180) is controlled by a scheduler (170). The scheduler (170) divides a predetermined period of tcycle seconds, wherein for each active data stream at least Rmax*tcycle data elements can be read from the storage medium, into n successive time intervals, each of t¿interval? seconds. For each data stream a corresponding buffer (125) is reserved for storing at least Rmax*(n+1)*t¿interval? data elements. The data is read from the storage medium (110) by repeatedly sweeping the storage medium (110) for a group of data streams. Immediately before causing the reader (180) to perform a next sweep, the scheduler (170) determines the composition of the next group of data streams to be supplied with data. At least data streams whose corresponding buffer (125) comprise less than Rmax*2*t¿interval? data elements are assigned to this group.

摘要： Requests are received for storing/retrieving and storing data from/to a plurality of storage devices (100). A processor (300) is designed for handling each request, based, e.g., upon the load of each processor. A request for retrieving data is forwarded directly from the designated processor to the storage device via a switch, (250). Responses from the storage devices are routed directly to the designated processor via the switch (250). The switch (250) independently routes the request for retrieving data and the responses between the storage devices (100) and the processor, based on information obtained by the processor. Data provided by a designated processor is stored on the storage devices (100) via a switch (250). The switch (250) independently routes the data to be stored directly from the designated processor to the storage devices (100), based on information created by the processor. Requests and responses are exchanged between the switch (250) and the storage devices (100) via at least one high-speed network channel.
