Abstract
A method and apparatus generates and transfers a stream of broadcast information which includes multiple video and audio information segments to a receiving device. Once received, the segments are stored in a cache and indexing information associated with the segments is made available to end users of the apparatus. The end users are then able to select which segment(s) they would like to receive, and the selected segment(s) is transmitted to the requesting user(s). In one embodiment, when a new segment is received, a determination is made as to whether it is a more recent version of another segment already stored by the apparatus. If it is a more recent version, then the older version is overwritten by the newer version.
