Abstract
Disclosed is a method and system for synchronously reproducing multi-media multi-information. The method is a method of combining a plurality of relevant files or a plurality of information streams that have an associated information relationship using a “multi-information modulation unit”, and then synchronously reproducing the relevant files or the information streams using a dedicated player capable of synchronously reproducing and playing back the multi-information. The step of synchronously recording the multi-information in the method is to insert “non-audio/video information” into an “audio/video steam before compression or after compression or a file thereof” using the “multi-information modulation unit”, that is, to embed some “additional information blocks” carrying the “non-audio/video information” into necessary “video frames” or “audio frames” and/or create or insert some “additional information frames” carrying the “non-audio/video information” between the necessary “video frames” and “audio frames”.
