Abstract: 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.

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

Abstract: Methods, systems and computer program products to synchronize timing of data transmissions between wireless and wired networks using a combined wireless gateway and cable modem are provided herein. The method includes the step of generating an indicator prior to a look-ahead time period and transmitting a poll to a wireless device upon sending the indicator. The look-ahead time period is a time period from transmitting the indicator to transmitting the DOCSIS frame. The method further includes the step of receiving data from the wireless device and encapsulating the data in a DOCSIS format to generate a DOCSIS frame. The method also includes transmitting the DOCSIS frame at a start of a next transmit opportunity to a cable modem termination system (CMTS).
