Metadata sharing system

摘要

PPROBLEM TO BE SOLVED: To release metadata created by individual audience so that it can be shared among multiple audiences. PSOLUTION: A system comprises multiple media data audio-visual devices 10-i serving as clients configured in a way that media data can be used together with metadata for viewing and listening, and a server 20 for data transmission and reception between the clients concerned. A metadata storage 23 in the server 20 accumulates metadata created by each media data audio-visual device 10-i. Each media data audio-visual device 10-i downloads metadata from the server 20 as needed and combines it temporally with media data accumulated in its media data storage 15 to view and listen the media data.
