ABSTRACT:
Systems and methods for remotely scheduling tasks that are transmitted to a set top box and implemented on the set top box. A task service includes a website that provides program guide data to users. From the program guide data, a user selects a task. The website generates a notification that includes the task and certain identifiers, including a set top box identifier and a sequence number. The notification is sent to a notification service, that repeatedly sends the notification to a broadcast service. The broadcast service ensures that the notification is transmitted to the set top box. The set top box detects the notification from the set top box identifier and implements the task on the set top box unless the task: has been previously handled.
