Abstract: Different data communication architectures deliver a wide variety of content, including audio and video content, to consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architectures distribute data across multiple orbital angular momentum channels in the bonded channel group.

Abstract: A media gateway that services a plurality of client devices may be used to combine a plurality of encoded multimedia transport streams, which may comprise a buffered copy of received encoded broadcast multimedia transport stream and an encoded local multimedia transport stream that pertains to the broadcast transport stream. The media gateway may decode the encoded broadcast multimedia transport stream to extract broadcast multimedia content carried therein based on determination of capabilities of one or more client devices used in playback of the content. The encoded local multimedia transport stream may be generated based on local multimedia content generated and/or captured via one or more client devices. The buffering duration of the received encoded broadcast multimedia transport stream may be adaptively determined, to ensure that the encoded local multimedia transport stream and the encoded broadcast multimedia transport stream are synchronized when they are combined.

The second network interface transmits the one or more of the transcoded plurality of media signals to a respective plurality of remote client devices over a second communication network.

Abstract: An IP gateway, attached to a source network and a destination network, handles an application session between a source client device and a destination client device. Application-level control messages in the existing application session may be time stamped by the IP gateway. Individual network round-trip delays (RTDs) associated with the attached networks may be calculated or determined utilizing the resulting time stamps. The IP gateway may time stamp one or more of the application-level control messages in the existing application session whenever transmission and/or reception of the application-level control messages occurs at the IP gateway. The resulting gateway related time stamps such as the gateway-to-source receive time stamp and the gateway-to-destination transmit time stamp may be stored.

Abstract: A participation device in a multiparty conference call may act as a server device and/or a client device for two-way audio and video (AV) streaming. A server device may encode a requested AV stream into a set of different encoding profiles that may be dynamically determined based on the varying channel conditions and device capacities of the client devices. At least a portion of differently encoded AV streams is selected and dynamically communicated to the client devices for display. Session parameters are determined according to the varying channel conditions and the device capacities of the client devices to create intended sessions. The selected encoded AV streams are communicated utilizing segment-based adaptive streaming techniques such as HTTP. A client device may access to a HTTP session to download an expected AV stream from the server device. The downloaded AV stream may be decoded into different decoding profiles for display as needed.

Abstract: A system may time-shift the distribution high-definition (HD) audio. The system can obtain an audio stream from a specified audio source, transcode the audio stream into an HD audio stream, and store the HD audio stream in a memory. The system may later forward the stored HD audio stream to a destination device, which can be a communication device linked to the system through a local telephone network or a remote communication device. The system can also store HD audio when a local communication device receives an incoming call request that interrupts a current HD audio distribution process. The system may resume distribution of the HD audio after processing the incoming call request from a point when the distribution was interrupted.
