Abstract: Systems and methods for restoring lost or corrupted data in packets that traverse a packet-switched network. In some embodiments, a device at the edge of a packet switched network may restore data that was originally inserted in a packet header by a sender, but overwritten or bleached during transport over a network by identifying an associated packet, and transferring a value from the associated packet to the packet.

Abstract: Systems and methods of this disclosure can operate to synchronize timing between communication devices and can include a timing server. The timing server can provide a communications interface for the exchange of timing messages to a first communication device. Using existing protocol messages defined in the M-CMTS architecture, additional communication devices can intercept, snoop, and extract timing information from messages between the first communication device and the timing server to adjust their internal clocks to maintain timing synchronization thereby reducing the number of communication interfaces required from a timing server.

Abstract: A multicast adaptive bit rate receiver is employed delay issuance of specific unicast HTTP adaptive bit rate media segment requests while waiting for receipt of stripped multicast media segments from a multicast server. An HTTP proxy may create a new internal state that waits for subsequent media segment URL requests. As the stripped multicast media segments are received, the HTTP requests queued in the proxy may be delivered to the local ABR client.

Abstract: A packet data flow processor applies a first level of Data Over Cable Service Interface Specification (DOCSIS) processing to packet flows that are not from trusted sources, and applies a second level of DOCSIS processing, simpler than the first level, to packet flows from the trusted sources.

Abstract: Methods, systems, and apparatuses can provide for adaptive streaming using non-local information. Non-local information identifying usage statistics associated with a network service group can be collected and used to derive session parameters associated with each of a plurality of sessions within the network service group. The non-local information can also be updated and the updated non-local information can be used to dynamically adjust the session parameters.

Abstract: Systems and methods of this disclosure can operate to re-synchronize timing between communication devices and can include a timing server. The timing server can provide timing messages containing timing correction values to communication devices that can synchronize the communication devices. If communication devices fail to receive timing messages, the communication devices may continue to provide communication services using their internal clocks that can drift over time. When timing messages are restored, the timing correction values can be significant enough to result in the loss of communications if immediately applied by communication devices. By gradually applying timing corrections over a period of time approaching the received timing correction value, communication devices can achieve re-synchronization while avoiding and/or minimizing the loss of communications.

Abstract: Multicast information contained in a request from an IP TV set top box for video content to an IGMP manager is passed to an SA processor to perform a lookup of an SA table. A result of the lookup is the frequency of the downstream legacy channel over which the requested content is being delivered from an edge QAM device. The SA processor instructs a legacy QAM tuner to tune the determined frequency. The IGMP manager selects packets corresponding to the request content based on a program identifier that is associated with the multicast address in the SA table. As selected packets are received by the IGMP manager, multicast address information is placed into them, and they are passed on from the manager to the IP TV set top box. The IP TV set top box receives the requested content packets based on the multicast address.

Abstract: A stream request is generated based on the stream address of a corresponding program selected from an electronic program guide that associates programs with corresponding IP multicast stream addresses by a subscriber/user device. The stream request is sent from the subscriber device to a broadband device, which compares the address in the request to available stream information listed in a content guide. The content guide contains information for all multicast streams that are available from a CMTS to the broadband device over DS channels of the current MAC domain. The broadband device locks to the stream that corresponds to the request, including tuning to a different DS channel if necessary. The broadband device may request another MAC domain if the stream is not available from the current one. After locking to a desired stream, the broadband device informs the CMTS so that it can adjust content guide user counts.
