Abstract
A method and system are proposed for storing streamed multimedia data in a multimedia cache. The method includes: receiving portions of a multimedia data stream item from a multimedia source; pre-storing a plurality of the multimedia data stream portions in a buffer in the order in which the portions are received; determining the temporal position of the pre-stored multimedia data portions in the multimedia data stream in order to identify consecutive sequences in the media data stream; rearranging the pre-stored multimedia data stream portions to form at least one temporally contiguous data stream portion and storing each contiguous data stream portion as a single segment in a cache file. The pre-storage and subsequent rearrangement or reorganisation of the received media data stream portions means that all data stream portions that are received out of order but are sequential within the media data item can be placed in the correct temporal sequence and also combined into a single data portion, thus facilitating both the subsequent storage of the media data in a cache and the retrieval of this data.
