Abstract: The disclosed embodiments provide a system that facilitates broadcast transmission in a distributed content delivery network. The system includes a node in the distributed content delivery network that plays a content stream received over the distributed content delivery network. The node includes a leadership-management apparatus that identifies the node as a peer leader in a local network of the distributed content delivery network. The node also includes a broadcasting apparatus. Upon identification of the node as the peer leader, the broadcasting apparatus obtains the content stream from a content source, broadcasts the content stream to other nodes in the local network, and adjusts a bit rate of the content stream based on one or more attributes associated with obtaining the content stream from the content source.

Abstract: A mechanism for maintaining information variety in an information receiving system which receives a stream of incoming objects each corresponding to one or more content categories. The information receiving system includes an object store for holding a set of cached objects for access by a consumer of information. The information receiving system includes an object store manager that determines which of the incoming objects are to be added to the object store and which of the cached objects are to be evicted from the object store such that a variety of information according to a set of consumer interests in the content categories is maintained in the object store.
