发明名称 Apparatus and Method for Secure Distribution of Media Data
摘要 A technique for playing a media file by a data processing system. A degraded initial version of the media file is received from a sending data processing system. A supplemental version of the media file is received from the sending data processing system. The degraded version of the media file is merged with the supplemental version of the media file to form a combined media file, with the combined media file being played. In one embodiment, the degraded version of the media data has a reduced quality that is obtained by removing portions of the data and filling in the removed portions with dummy data. During a subsequent rebuilding of the media data by the receiving/recipient data processing system, a supplemental version of the media data is received and merged/combined with the degraded version to form a copy that corresponds to the original, high-quality version of the media data.
