摘要
An arrangement is provided where all applications in an interactive media environment run on a single application thread in a media player. Event queues are utilized to schedule the application thread's processing of workitems corresponding to events that occur in the environment. Workitems include methods to be invoked when the workitem is processed and arguments for the method. Workitems further include a begin time and an end time and are ordered in the event queue first by begin time followed by the order in which they were inserted into the queue. The application thread marks workitems whose begin times corresponds to the current or previous time and then processes marked workitems from the queue in order. Such processing is committed so that once the application thread begins processing of a workitem it does not stop. Workitems are dropped from the event queue if their end times have been passed.
