Abstract:
1. A system implemented on a machine that asynchronously distributes multimedia content, comprising: one or more processors; an interface component that receives multimedia content supplied by a multimedia publisher; an encryption and key generation component, executable by the one or more processors, that applies a time-sensitive lock to the multimedia content and disseminates the locked multimedia content to a plurality of disparate clients for storage to associated storage media, and at a later time disseminates a time sync signal that unlocks the locked multimedia content for playback at predetermined times established by the system, wherein the time-sensitive lock includes a time-sensitive key disseminated concurrently with the time-sensitive lock and the locked multimedia content in a first time interval, the time-sensitive lock being unlocked by the time sync signal generated by the encryption and key generation component in a plurality of subsequent time intervals, thereby controlling when users can view different portions of the multimedia content; a synthesizing component that filters information received from a variety of inputs; and a context summary component that determines context associated with the variety of inputs and disseminates the locked multimedia content or the predetermined time sync signal based on the context.
