    摘要: Methods for generating file relationship data, and media file systems that generate file relationship data A method of generating, in a media file system comprising a data store and a file record database, file relationship data for a first media file in the media file system. The method determines the essence data in the data store from which the first media file was derived, by determining from the file record for the media file in the file record database details of any previous media files in the media file system from which the media file was created. If the media file was not created from any previous media files, the essence data in the data store that constitutes the media file is determined from the file record. If on the other hand the media file was created from any previous media files, the previous steps are repeated for the previous media files. The file relationship data is the generated using the details of the determined essence data.

    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: 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: 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: The present invention seeks to provide an improved file system that provides essence data for a media file in a way that does not require the contents of the entire file to be available before any file data can be provided. The present invention is reflected in 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. The method comprises 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 is then created in the file record database. In response to a request for the location of essence data within the file, a location given by the determined layout of the media file is returned. Further, a stream of essence data corresponding to the contents of the programme is received and the received essence data is stored in the data store. 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 is returned according to the determined layout of the media file.
