Abstract
A data-processing system facilitates processing a data stream to assist other devices to pre-fetch elements of the data stream, out-of-sequence, for uninterrupted playback. During operation, the system can receive a data file, and segments the data file into a sequence of content objects. The system then determines a target content object that is to be processed out-of-sequence, and a corresponding source content object. The system then inserts a reference to the target content object, into the source content object, and stores the sequence of content objects. A client device can disseminate interest to obtain the data stream's content objects. Upon receiving a content object, the client device can determine whether the content object includes a reference to other content objects. If so, the client device can disseminate interests for these referenced content objects.
