摘要： A video server and a file management method which can erase an unnecessary program data file promptly are provided. Video server S divides processing of management of files performed by one frame into 11 sections, assigns five sections to playing process, assigns five sections to recording process and assigns one section to erasing process and performs processing of the file management. Server S supervises the file processing under executing. When a number of sections which perform the playing process or a number of sections which perform recording process is smaller than 5 and there is a demand of the erasing process for more than 2 files, server S assigns the section which is not used to the erasing process and unnecessary files are erased.

摘要： A packet timing method and apparatus for use with a system for controlling digital TV program start time. An encoder inserts a program clock reference (PCR) timing field, in at least two intervals in transport packets. A decoder generates a decoder-clock signal from the PCR timing signal, which has the same frequency as an encoder-clock signal used for encoding. In response to the PCR timing field, a rate of consumption of data is synchronized with a rate of production of data, and chroma sub-carrier is synchronized.

摘要： A video system for providing a large number of video streams. The video system includes a video server and dividing means. Storage means, a switch and control means are located at the video server. The video server has a plurality of central-processing units (CPUs). The dividing means divides a plurality of input video-streams entering the video system, and sends the divided plurality of input-video streams, with each divided video stream identified with a separate Ethernet address, to the video server. The storage means stores an input video-stream of the plurality of input video-streams as a stored-video stream. The switch routes an input-video stream of the plurality of input-video streams to the storage means. The control means controls the storage means to replay the stored-video stream and to control portions of the stored-video stream at an appropriate time, and controls the plurality of CPUs at the video server to work in parallel.

摘要： The disk scheduling algorithms try to service a request with lower priority and strict deadline only if serving this request is not going to violate the deadline constraints of a higher priority request. One of the algorithms uses a single queue to hold all the requests regardless of their priority. The single queue is reorganized after the arrival of a new request according to the order requests would be serviced. A second algorithm uses multiple queues. Each queue holds only requests with the same priority, and the requests in each priority queue are sorted according to their deadlines. The decision of servicing a request is made at scheduling time.
摘要翻译：磁盘调度算法只有在服务该请求不会违反较高优先级请求的期限限制时，尝试以较低优先级和严格的限制时间来服务请求。其中一种算法使用单个队列来容纳所有请求，而不考虑它们的优先级。在根据订单要求提供服务的新请求到达后，重新组织单个队列。第二种算法使用多个队列。每个队列仅保存具有相同优先级的请求，并且每个优先级队列中的请求将根据其最后期限进行排序。处理请求的决定是在调度时间进行的。

The object of the present invention is to provide a method for storing data in a disk array based on block division by dividing the blocks of large amounts of data, such as video/audio data stream into split blocks and a method for controlling input/output of a disk array based on multiple command pending. The data placement method includes the steps of: a) dividing data into logical blocks based on an input/output unit of a file system; b) dividing the logical blocks into split blocks by the number of disks included in the disk array; and c) commanding to store the split blocks in the disks of the disk array sequentially.

摘要： Systems and methods for streaming of multimedia files over a network are described. A streaming delivery accelerator (SDA) receives content from a content provider and streams the receives content to a user when a quality metric exceeds a predetermined value. A similar quality metric applies to caching and storing the received content in the SDA' cache. The caching process can be iterative, with only content not previously retained in the SDA's cache being requested from and retransmitted by the content provider.
摘要翻译：描述了通过网络流式传输多媒体文件的系统和方法。当质量度量超过预定值时，流传输加速器（SDA）从内容提供者接收内容并将接收的内容流传输给用户。类似的质量度量适用于将所接收的内容缓存并存储在SDA缓存中。高速缓存过程可以是迭代的，只有内容提供者才从SDA的缓存中先前保留的内容不被请求和重传。
