First Claim
Patent Images
1. A method for delivering objects to one or more receiver units, comprising:
- receiving a number of incoming objects, each object corresponding to one or more classes;
maintaining objects from a variety of classes in an object schedule, wherein each object has a utility factor comprising one or more of the importance of the object, the timeliness of the object, and the number of objects previously transmitted in a same or related class as the current object; and
delivering selected objects from the object schedule to the one or more receiver units.

Abstract
Methods and apparatus are disclosed for efficiently scheduling incoming information objects so that timely objects from a variety of content classes are scheduled for broadcast. The incoming information objects are preferably received from one or more information sources, and are tagged with attributes that associate each object with one or more classes of information (e.g., sports, news, etc.), and provide a gauge of the timeliness or ‘age’ of the object. The tags can be used to select and broadcast objects from a variety of classes, and to identify the most timely objects at any give time.

19. A method for scheduling objects for delivery to one or more receiver units, the method comprising:
-
receiving one or more incoming objects, each having a utility factor; scheduling the objects for delivery in an initial scheduling order, the value of the utility factor for each of the objects being dependent, at least to some degree, on the position of the object in the schedule; calculating an overall schedule utility factor for the schedule by combining the utility factors of each of the scheduled objects using a predefined function; reordering the scheduled objects so that the overall schedule utility factor is increased; and delivering one or more of the objects from the top of the schedule. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. An information delivery system, comprising
a receiver for receiving a stream of incoming objects, each object corresponding to one or more classes; -
object schedule for storing a set of the incoming objects, wherein each object has a utility factor comprising one or more of the importance of the object, the timeliness of the object, and the number of objects previously transmitted in a same or related class as the current object; object scheduler for determining which of the incoming objects to add to the object schedule and which of the cached objects to evict from the object schedule, such that objects from a variety of classes are maintained in the object store; and delivery means for delivering selected cached objects from the object schedule to one or more receiver units based on the position of the object in the object schedule. - View Dependent Claims (34, 35, 36, 37, 38)

39. A system for scheduling objects for delivery to one or more receiver units, comprising:
-
a receiver for receiving one or more objects, each object having a utility factor; an object scheduler for scheduling the objects for delivery in an initial scheduling order, the value of the utility factor comprising one or more of the importance of the object, the timeliness of the object, and the number of objects previously transmitted in a same or related class as the current object; the object scheduler calculating an overall schedule utility factor for the schedule by combining the utility factors of each of the scheduled objects using a predetermined function; the object scheduler reordering the scheduled objects so that the overall schedule utility factor is increased; and delivery means for delivering one or more of the objects from the top of the schedule to the one or more receiver units.
