Abstract: A flow bonder at a CMTS and another at a cable modem distribute packets of a service flow over multiple channels and collect them in the downstream direction respectively; vice versa in the upstream direction. The service flow may include video and data streams that are provided to the CMTS via an IP network. IP header information is stripped form video packets and remultiplexed with packets of other video streams. The remultiplexed video stream packets are combined into a composite stream, which is transported using multiple bonded-flow RF channels over an HFC. A set top box receives the composite stream and separates data from video packets based on IP information. Video packets are assembled according to information from a multiple program transport stream table based on a program selected by a user.

Abstract: A system for increasing bandwidth to a communication device, comprising: a packet scheduler; and a transmitter; the system configured to operate the packet scheduler to schedule packets of a service flow onto multiple media access control (MAC) channels forming a MAC channel group before operating the transmitter to send the scheduled packets from an origination device toward a destination device, the packet scheduler waiting a maximum group cross channel skew time for an out-of sequence packet, the maximum group cross channel skew time a maximum of multiple pair cross channel skew times, one pair cross channel skew time associated with each pair grouping of MAC channels configured to be formed from the MAC channel group; and the system configured with a setting to allow only a single channel of the multiple channels of the MAC channel group to carry DOCSIS messages, and to override the setting to share at least some of the channels of the MAC channel group among multiple cable modems while the MAC channel gr

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: Systems and methods can provide a gateway-based video client proxy subsystem for managing delivery of segmented video in a stateful system. Such systems can operating to provide segmented video streams client devices via customer premise gateway devices. The system can receive state information from the customer premise gateway devices for use in managing network resources associated transmitting with the segmented video streams, and deriving allocations of bandwidth to flows associated with the client devices based upon the state information received from the customer premise gateway devices.

Abstract: Methods, systems, and computer readable media can be operable to facilitate the provisioning of a user interface with video frame tiles. Specific content sources or pieces of content may be identified according to various parameters, and media renderings of the associated content may be generated. The media renderings may be processed at a device receiving the content, and a user interface including one or more of the media renderings may be generated. The media renderings may be organized within the user interface as individual video frame tiles.

Abstract: A flow bonder at a CMTS and another at a cable modem distribute packets of a service flow over multiple channels and collect them in the downstream direction respectively; vice versa in the upstream direction. The collector uses a service flow identifier and a sequence number identifier inserted by the distributor into each packet of the flow to reassemble the packets into the order they left the distributor. Packets received at the collector are stored to a buffer. If a stored packet is the next to be transmitted, it is transmitted. If not, the collector waits a predetermined period until the next packet to be sent is received. If it is not received during the wait period, the previously stored packet is sent. The wait period is based on the maximum transmission time difference between any two of the multiple channels.

Abstract: A device receives packets associated with a program stream at an addressable communications port, and assigns them to one of a plurality of QAM channels. Multiplexed program packets, DOCSIS data or multimedia packets or a combination of both, are transmitted over the QAM channel. DSG messaging transports requests for content to a server, transports queries to mapping tables and returns information from the tables to a manager that, along with processors, determine which channel to use for downstream transport of the multiplexed streams. The manager assigns a connection identifier corresponding to a channel and program number combination to the packets, and sends the identifier, via DSG, to the requesting/receiving user device; the identifier instructs the user device how to tune and receive the requested packets. The identifier may use seven bits for program numbers, two for output port number and two for channel frequency.

Abstract: A direct broadcast satellite system delivers video content to a subscriber and a CATV network is used to simultaneously provide data services to the same subscriber. Since the CATV system is not used to deliver video/television programming channels, these same channels can be used to transport downstream and upstream data signals. To provide upstream performance and immunity to noise, upstream data traffic signals are upconverted at a subscriber's cable modem for transmission by channels having center frequencies higher than 54 MHz. Cable modem circuitry combines the conventional output signal with the output of a local oscillator to raise the carrier frequency of upstream traffic before it is introduced to the CATV network. Thus, upstream traffic can be carried by channels higher than 54 MHz. This upstream signal is received by a block converter that lowers the carrier frequency back to a conventional channel frequency before processing by a standard CMTS.

Abstract: A direct broadcast satellite system delivers video content to a subscriber and a CATV network is used to simultaneously provide data services to the same subscriber. Since the CATV system is not used to deliver video/television programming channels, these same channels can be used to transport downstream and upstream data signals. To provide upstream performance and immunity to noise, upstream data traffic signals from a subscriber's cable modem are upconverted for transmission by channels having center frequencies higher than 42 MHz.

Abstract: Cable modem circuitry is connected via a bus interface to decoder circuitry in a set top box to receive various types of content and distribute the content to outputs corresponding to the content type. The outputs include video, audio, data (USB host), telephony and asynchronous interface. The content is received on a single broadband connection from a single service provider rather than multiple connections from multiple service providers. The DOCSIS protocol, and features that are a part thereof, are used to facilitate efficient transmission of content to a subscriber.

Abstract: A user interface accesses a storage device and allows a user to change telephony features in a system that provides telephony service over IP. A user logs in to an MTA of a telephony terminal and chooses which features to change and which options associated with the chosen feature(s) is to be selected. The features may apply to incoming call features, such as ring cadence, and outgoing features, such as call blocking.

Abstract: A converged multi-media portal for coupling a plurality of multi-media signals carried on a single network medium to a plurality of corresponding multi-media devices includes a backplane, having a plurality of connectors, wherein the at least one connector is capable of accepting a network interface module. A plurality of the connectors are capable of accepting multi-media processing modules. Within the converged multi-media portal, the backplane enables communication between the network interface module and the multi-media processing modules disposed within the connectors. The network interface module receives at least one type of data signal and directs the at least one type of data signal to one of the multi-media processing modules according to a signal destination address. Each of the multi-media processing modules receives a multi-media signal from the network interface module and routes at least one multi-media signal to a corresponding multi-media device.
