Abstract:
A method includes receiving, at a multimedia device, a data stream representing multimedia content, the data stream comprising first timing information for the multimedia content, and metadata representing interactive event information associated with the multimedia content, the metadata comprising second timing information for the interactive event information. During the playback of the multimedia content, a first user interactive event is identified that is associated with a first time point in the playback of the multimedia content based on the interactive event information, and the first user interactive event is performed concurrent with the first time point in the playback of the multimedia content.
