System and method for synchronization of multimedia streams

A method for synchronizing initiation of media operations in a multimedia recording and playback system, comprising the steps of:

• in a starter process, receiving the current time from a clock means, assigning the received current time as an initialization-time value, determining a zero-time value by adding a process preparation time to the initialization-time value, broadcasting the zero-time value to at least one media process;
• and
• in the media process, receiving the zero-time value, determining a media start-time by combining an offset time with the zero-time value, and upon the current time reaching the media start-time, initiating the media operation,
• thereby, synchronizing initiation of the media operations.

A method for synchronizing media recording in a multimedia recording and playback system, comprising the steps of:

• in a starter process, receiving the current time from a clock means, assigning the received current time as an initialization-time value, determining a zero-time value by adding a process preparation time to the initialization-time value;
• broadcasting the zero-time value to at least one media process;
• and
• in the media process, receiving the zero-time value, upon the current time reaching the zero-time value, repeating for each media event the sub-steps of obtaining the current time from the clock means, determining an event offset based on the zero-time value and the current time, logging the event offset in association with the media event, recording the media event,
• thereby, synchronizing the media recording.

• in a starter process, receiving the current time from a clock means, assigning the received current time as an initialization-time value, determining a zero-time value by adding a process reparation time to the initialization-time value, broadcasting the zero-time value to at least one media process;
• and
• in the media process, receiving the zero-time value, determining a media start-time by adding an offset time to the zero-time value, upon the current time reaching the media start-time, repeating for each media event the sub-steps of obtaining the current time from the clock means, determining an event offset based on the zero-time value and the current time, logging the event offset in association with the media event, recording the media event,

A method for synchronizing media playback in a multimedia recording and playback system, comprising the steps of:

• in a starter process, receiving the current time from a clock means, assigning the received current time as an initialization-time value, determining a zero-time value by adding a process preparation time to the initialization-time value;
• broadcasting the zero-time value to at least one media process;
• and
• in the media process, receiving the zero-time value, accessing a log of event offset times associated with a plurality of media events, for each logged event offset time, performing the sub-steps of readying the associated media event for playing, and when the event offset time arrives, playing the media event,
• thereby, synchronizing the media playback.

A method for synchronizing initiation of events in a multiprogramming computer system, comprising the steps of:

• in a starter process, receiving the current time from a clock means, assigning the received current time as an initialization-time value, determining a zero-time value by adding a process preparation time to the initialization-time value, broadcasting the zero-time value to at least one receiving process;
• and
• in the receiving process, receiving the zero-time value, upon the current time reaching the zero-time value, initiating the event,
