A method is provided that includes receiving a data request from a requesting device requesting data from a data source, looking up, in a blockchain ledger, a transaction corresponding to the data request to validate the data request, forwarding the validated data request to a data server, receiving a data response from the data server in response to the data request, wherein the data response comprises the requested data from the data source, and forwarding the data response to the requesting device.

Blockchain-enforced data access control

Various embodiments of the present disclosure improve existing multi-layer and other network technologies by routing and processing client requests that require machine learning based on the machine learning capabilities of each network device and/or other computer resource characteristics of different network devices. This ensures that network latency and throughput, among other computer resource consumption characteristics, will be improved as machine learning processing can occur at the most suitable network device or be distributed among various suitable network devices.

Distributed machine-learning resource sharing and request routing

A system controls a transmission of a sequence of compressed video data from an encoder buffer to a network for delivery to a decoder buffer. Control of the transmission includes to: determine characteristics of a video transmission path between the encoder buffer and the decoder buffer, the characteristics comprising at least one of a buffer size of the decoder buffer, an input rate of the decoder buffer, and a buffer size of an equivalent intermediary buffer of the video transmission path; determine a transmission rate from the characteristics of the video transmission path and from the sequence of compressed video data, the transmission rate being determined such that a target quality of service value can be guaranteed for the entire sequence of compressed video data transmitted at the determined transmission rate to the decoder buffer; and control transmission of the sequence of compressed video data at the determined transmission rate.

Compressed video buffering

In some aspects, the disclosure is directed to methods and systems for coexistence management. A first access point operating in an unlicensed frequency band using a first RAT receives, from a second access point operating in the unlicensed frequency band using a second RAT, information regarding operation of the second access point in the unlicensed frequency band. It is determined, using the received information, that the first access point or the second access point is using a first share of the unlicensed frequency band that is below a predetermined threshold, indicating an imbalance of usage between the first RAT and the second RAT. A transmission parameter of the first access point for operating in the unlicensed frequency band using the first RAT is adjusted according to the determination. The first access point transmits the one or more packets using the adjusted transmission parameter, to cause the first access point or the second access point to use an updated share of the unlicensed frequency band that is closer to the predetermined threshold than the first share.

Adjusting transmission parameters to support coexistence fairness

A method, system and computer program product in a wireless gateway to provide secured communications over a wireless network and a wired network is provided herein. The method includes the steps of receiving a first authentication credential from a wireless device and mapping the first authentication credential to a second authentication credential. The method further includes transmitting the second authentication credential to an authentication server and receiving a first authentication response from the authentication server. The method also includes generating a first shared secret and a second shared secret if the first authentication response indicates that authentication is successful and transmitting a second authentication response to the wireless device. The first shared secret is used to setup a first secured channel for communications with a service provider over a wired network and the second shared secret is used to setup a second secured channel for communications with the wireless device.

Security integration between a wireless and a wired network using a wireless gateway proxy

An apparatus and a system are provided to proxy one or more media signals between at least one local client device and at least one remote client device. For instance, the apparatus can include a first network interface, a rate controller and media transcoder, and a second network interface. The first network interface receives a plurality of media signals over a first communication network, where the plurality of media signals is encoded into at least one codec format. The rate controller and media transcoder transcodes one or more of the plurality of media signals into a different codec format based on channel and processing capabilities associated with one or more local client devices and one or more control messages. 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.

Communication over bandwidth-constrained network

An IP multimedia gateway (IMG) receives content sharing service profiles generated by a service manager for communication devices that are coupled to the IMG. Content and/or content information that is received for communication to a first device, is communicated to other devices in response to a request. Content sharing profiles comprise permissions, group members, user preferences, device capabilities and security profiles. Content streams communicated to the first device may be shared with a second device based on the profiles. The second device may share additional streams with the first device. The first device or other devices may communicate the request. The content may be received from a service manager network device. The IMG and a communication device that may display the content may be integrated in a set-top-box or digital TV. Login access is enabled to devices for requesting content. Cooperation with other IMGs may enable discovery and/or content communication.

Method and system for providing content remotely via one or more IP multimedia residential gateways

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.

Time-shifting distribution of high definition audio data

An IP multimedia gateway (IMG) determines device capabilities and proposed service priority profiles of communicatively coupled client devices. The determined device capabilities and proposed service priority profiles are transmitted to service managers for service scheduling. Device capabilities of the communicatively coupled client devices are configured or prioritized based on available actual service priority profiles from the service managers. The configured device capabilities are transmitted to the service managers for subsequent service scheduling. Services provided by the service managers are announced based on the available actual service priority profiles. The IMG communicates content for the announced services between the communicatively coupled client devices and the service managers. The IMG may allow the user of a client device to access desired content via other client devices. Content and/or downloaded content for carrier grade services are provided to one or more non-carrier grade client devices when needed.

Method and system for prioritizing and scheduling services in an IP multimedia network

A video reception device, comprising a single video decoder, may dynamically allocate media-processing resources based on QoS parameters associated with the received time-sensitive and non-time-sensitive video streams. The single video decoder is utilized to decode the content of the received time-sensitive and non-time-sensitive video streams for display. The QoS parameters associated with the received time-sensitive and non-time-sensitive video streams are mapped to corresponding media-processing resource requirements at the video reception device. The video reception device performs resource allocation for the received time-sensitive and non-time-sensitive video streams based on the corresponding media-processing resource requirements. Multi-dimensional resources allocation metrics are selected or formed from the corresponding associated QoS parameters for media-processing resource allocation. The video reception device starts resource allocation for the received time-sensitive video streams. Un-used portions of the allocated media-processing resources to the received time-sensitive video streams are re-allocated to process the received non-time-sensitive video streams.

Utilizing multi-dimensional resource allocation metrics for concurrent decoding of time-sensitive and non-time-sensitive content

Media gateways (MGs), grouped into a hierarchy, are operable to provide a multiparty conferencing among client devices. Gateway resources such as processors, Codecs and network interfaces are aggregated at each MG to establish distributed connection sessions based on resource management metrics such as minimizing total network. The distributed connection sessions are utilized to provide the multiparty conferencing. Each MG may aggregate the gateway resources, which may be determined utilizing a look-up table, from other MGs for sharing among the MGs. Each MG may be activated to provide the media gateway controller (MGC) processing utilizing the shared aggregated gateway resources. A MG may be de-activated from the MGC processing when needed and the associated connection sessions may be subsequently released. Gateway resources are managed at each MG based on the resource management metrics in order to establish distributed connection sessions to support the multiparty conferencing among the client devices.

Distributed resource management for a plurality of local media gateways to provide video conferencing

An IP multimedia residential gateway (IMRG) determines device capabilities and service priority profiles of client devices. The determined device capabilities and service priority profiles, comprising service classes and service class priorities, may be transmitted to the service managers for service deployment. The service managers may provide services to client devices based on corresponding device capabilities and service priority profiles. The IMRG may track device capabilities and service priority profiles for self-configuration. Available services supported by networks may be discovered during network discovery. The discovered services are announced to the client devices. The IMRG may communicate content of the announced services with the client devices based on corresponding device capabilities and service priority profiles. The service managers schedules services for the client devices based on corresponding device capabilities and service priority profiles, and may communicate content of the scheduled services to the client devices via the IMRG.

Method and system for service discovery and deployment in an IP multimedia network

A method and system virtualizes bandwidth. The system may include multiple communication interfaces to communicate across a hybrid network containing multiple networks of different types, technologies, protocols, topologies, or other network characteristics. The system may aggregate the bandwidth of the multiple communication interfaces into an aggregated virtualized bandwidth. When a bandwidth request is received, the system may determine a bandwidth allocation across the aggregated virtualized bandwidth. The system may also determine a communication resource allocation for the bandwidth allocation, which may assign any number of the communication interfaces. The system may then communicate application data across the allocated bandwidth.

Bandwidth virtualization

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.

Multiplexing, synchronizing, and assembling multiple audio/video (A/V) streams in a media gateway

In an IP multimedia gateway, locations corresponding to communicatively coupled communication devices are determined and transmitted to a service provider device (SPD) that provides services to the communication devices. Communication devices receive location based service profiles from the (SPD) based on the determined locations. Services content from the (SPD) is communicated with the communication devices and/or with the (SPD), based on the profiles. The determined locations are received from communication devices which may be local or remote. A device location map is generated to be displayed by communication devices. The gateway may be integrated in an STB/DTV that displays the determined locations. Content is communicated to communication devices based on their location. The (SPD) may provide content and/or control information for communication device services. Locations are associated with client devices for detecting cloned client devices where determined locations are different than associated locations and/or for restricting services based on location.
