Accessing annotations across multiple target media streams |
摘要 |
An annotation server uses a hierarchical annotation storage structure to maintain a correspondence between a plurality of multimedia stream annotations and a hierarchically higher group identifier. The annotations corresponding to the different multimedia streams can easily be accessed concurrently by referencing the group identifier.
