Abstract: A system and method of delivering video content is disclosed. In a particular embodiment, the method includes receiving channel selection data from a set-top box device via an Internet Protocol Television (IPTV) access network. The channel selection data indicates a selection of an IPTV channel. The method also includes sending a rapid channel change (RCC) request to a distribution switch/router system via a subscriber virtual local area network (VLAN) associated with the set-top box device after receiving the channel selection data. The RCC request indicates the selected IPTV channel.

Abstract: A method of providing video content includes receiving a channel change data packet from a set-top box device at a subscriber premise via a packet-based video distribution network. The channel change data packet includes data indicating a requested channel and a channel change index value. The method also includes reading the channel change data packet to identify the channel change index value. The channel change index value indicates an available bandwidth at the subscriber premise to receive video content of the requested channel via the packet-based video distribution network. The method also includes allocating an overhead bandwidth to the set-top box device based on the channel change index value.

Abstract: A method includes receiving data from a set-top box device at an access system via an access network, the data indicating a selection of a channel at the set-top box device, the data including a multicast group address. The method also includes sending copies of video data packets of the channel from the access system for storage in a first-in first-out cache associated with the channel. The method further includes automatically connecting the set-top box device to a multicast stream of the selected channel after a particular number of video data packets are sent to the set-top box device from the cache. The particular number of video data packets corresponds to a time period between communicating successive random access point packets of the channel and is less than a capacity of the cache.

Abstract: A method includes receiving an indication of at least one detected security issue at a network device. The indication is received at a security manager processor from a security agent. The method includes selecting, via the security manager processor, at least one executable security object responsive to the indication. The security manager processor verifies compatibility between the at least one executable security object, the network device, and communication media. The method also includes sending the at least one executable security object to the network device via the security manager processor to provide a protective security measure to the network device against the at least one detected security issue upon execution of the at least one executable security object.
