    摘要： A method of providing file data for a media file of a pre-determined format from a file system comprising a file record database and a data store, wherein the media file corresponds to a programme consisting of a plurality of segments, and wherein the segments included in the programme are dynamically determined. The method comprising the steps of receiving details of the programme including the duration of the programme, and determining the layout of the media file in the pre-determined format from the received details of the programme, the layout including locations for essence data within the file. A file record for the media file in the file record database is then created. In response to a request for the location of essence data within the file, a location given by determined layout of the media file is returned. Further, in response to an instruction that a segment is to be included in the programme, essence data corresponding to the contents of the segment is obtained. Then, in response to a request for a portion of essence data from the media file corresponding to a time period of the programme, essence data derived from the received essence data according to the determined layout of the media file is returned.

    摘要翻译： 一种为包括文件记录数据库和数据存储的文件系统提供预定格式的媒体文件的文件数据的方法，其中该媒体文件对应于包括多个段的程序，并且其中包括的段 在程序中是动态确定的。 该方法包括以下步骤：接收包括节目持续时间的节目的细节，并且从接收到的节目详情中确定具有预定格式的媒体文件的布局，该布局包括文件内的本质数据的位置 。 然后创建文件记录数据库中媒体文件的文件记录。 响应于对文件内的基本数据的位置的请求，返回由确定的媒体文件的布局给出的位置。 此外，响应于节目将被包括在节目中的指令，获得与该片段的内容相对应的基本数据。 然后，响应于对应于节目的时间段的来自媒体文件的一部分基本数据的请求，返回根据所确定的媒体文件的布局从接收到的基本数据导出的基本数据。

    摘要： A method of providing file data from a file system comprising a data store and a file record database. The method comprises the steps of receiving a request to open a file in the file system and determining the desired properties of the file using the syntax of the request. A file record is then created in the file record database based on the determined properties of the file, and a file handle for the file record is returned. Data constituting the requested file from data in the data store is generated based on the determined properties of the file, and in response to a request to read a portion of data from the file, a corresponding portion of the generated data is returned.

    摘要： There is described an editing system in which image data representing an initial moving image input in a first format at a corresponding rate is stored in a store (2) and is manipulated to produce image data representing an edited moving image for output in a second format at a corresponding data rate. The system is arranged such that processing is effected at a data rate which is variable and determines the second data rate.

    摘要： A video processing system comprises a video store 7 for storing video data defining a plurality of clips. For each of the clips an associated set of clip data is stored in an editing memory 12. Each set of clip data comprises processed data identifying processing to be applied to the video data forming the clip and history data identifying the origin of the clip. The video data forming the clip or clips is processed by a processor 6 in accordance with the processing identified by the process data associated with the or each clip to produce video data forming a process clip for storage in the video store 7 and an associated set of clip data for storage in the editing memory 12.

    摘要： A data storage apparatus 20 comprises several disc stores 21 to 24 connected to respective RAM buffers 37 to 40 by respective data interfaces and highways 25 to 36. Sets of data are stored in the disc stores with the data in each set being distributed among the disc stores. The apparatus comprises a controller 51 which, in response to an external request for data, generates control data identifying one or more sets of data to be transferred between the disc stores and the RAM buffers. The control data is transferred to the disc stores 21 to 24 via the respective data interfaces and highways 25 to 36. When data is ready for transfer a signal is sent from the interfaces 33 to 36 and once the controller has received signals from each of the interfaces it enables data to be transferred between the interfaces and respective RAM buffers. A data highway 49 is provided for connection to external apparatus for a substantially continuous sequential transfer of the data in the identified set or all of the identified sets. Data is transferred between the RAM buffers 37 to 40 and the data highway 49 under the control of the controller 51. The highway 49 may be provided with error checking circuitry 55 to 57.
