摘要： A method of providing file data for a converted video file from a file system. After receiving a request for a portion of file data from the converted video file, an existing video file from which to derive the file data is determined. A portion of file data from the existing file that corresponds to the requested portion of file data is then determined, and file data from the portion of file data from the existing file data, by converting the portion of file data to file data of a different quality. The generated file data is then returned.

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.
摘要翻译：一种从包括数据存储和文件记录数据库的文件系统提供文件数据的方法。该方法包括以下步骤：接收在文件系统中打开文件的请求，并使用请求的语法确定文件的期望属性。然后根据确定的文件属性在文件记录数据库中创建文件记录，并返回文件记录的文件句柄。基于所确定的文件属性生成构成数据存储器中的数据的请求文件的数据，并且响应于从文件读取数据的一部分的请求，返回生成的数据的相应部分。

摘要： A method of providing file data for a media file from a file system, where the format of the file requires that the file comprise a plurality of segments of file data located at pre-declared locations within the file. The file data making up the file is based upon derived file data. After receiving a request to open the file, a maximum segment length for the file is determined based on the desired properties of the file. In response to a request for the location of a segment within the file, a location calculated by considering each segment of the file to have the maximum segment length is returned. In response to a request for file data from a segment of the file, generated file data for the segment is returned, where the generated file data comprises the derived file data and padding data to give the generated file data the maximum segment length.
摘要翻译：一种从文件系统提供用于媒体文件的文件数据的方法，其中文件的格式要求文件包括位于文件内预先声明的位置的文件数据的多个段。构成文件的文件数据基于导出的文件数据。在收到打开文件的请求后，文件的最大段长度将根据文件的所需属性确定。响应于文件中段的位置的请求，返回通过考虑文件的每个段以具有最大段长度来计算的位置。响应于来自文件段的文件数据的请求，返回用于该段的生成的文件数据，其中所生成的文件数据包括导出的文件数据和填充数据，以使生成的文件数据具有最大段长度。

摘要： The invention comprises a file server system for providing user access to data stored in a storage means including a database and a high capacity store. The system includes means interacting with the database to present to a user file identifiers indicative of virtual data files apparently available from the system though not assembled into files, and responds to a request from the user for access to data in a virtual file indicated by a selected file identifier by assembling from the database and the high capacity store a file containing the selected data. The contents of selected files are constructed, from essence data (such as video image data) archived in the high capacity store, and associated metadata information stored in the database, when requested of the server; file headers being generated from data stored in the database and file payloads being assembled from the high capacity store. In a preferred embodiment, the system detects when an ordered sequence of files is being requested by the user and predicts the opening of the next file in the sequence, thereby enabling the next file to be prepared for user access prior to the receipt by the system of a request therefor from the user.
