Abstract: A multi-media broadcasting system that links a user profiles associated with a first user with a second user profile associated with a second user, where the first and second user profiles each comprise an indication of an interest common to the first and second users. The user profiles allow a user to customize a viewing experience via the broadcasting system. In addition, the system detects a content update to the first user profile, wherein the content update is associated with a content item that comprises content having a characteristic within the interest common to the first and second users. Furthermore, the system notifies the second user of the content update if the second user profile has not been updated with the content update.

Abstract: According to one embodiment, a digital stream, inclusive of an Internet Protocol (IP) datagram, is transmitted to a digital device. IP datagram comprises an IP header and a body segmented including a plurality of packets in an MPEG format such as MPEG-2 or MPEG-4 for example. The plurality of packets comprises (i) a first packet including a payload having content and a header that comprises a first packet identifier to indicate a type of the content contained in the payload of the first packet, and (ii) a second packet including a payload and a secondary packet identifier to indicate that its payload includes content duplicative of the content contained in the first packet. The second packet precedes the first packet in the digital stream. Upon detecting the presence of duplicative content, the duplicative content is recovered, but the content contained in the payload of the first packet is disregarded.

Abstract: A method comprising receiving a request for a connection over a network to an address is disclosed. The network conforms to a first network protocol, and the address conforms to a second network protocol. A field is compared to the network address. If the field matches the network address, a connection is established with a network node corresponding to the file. According to another embodiment of the invention, a Fibre Channel (FC) Virtual Interface (VI) is used to forward Transmission Control Protocol/Internet Protocol (TCP/IP) packets.
