  • Publication number: 20190342601
    Abstract: A method embodying the disclosure includes facilitating communications with mobile user equipment (UE) devices to form a collaborative group that uses a local wireless network. A UE receives video content from a content provider via a first network, presents the video content, and predicts a degradation of presentation quality for a portion of the video content. The UE sends requests to other UEs in the group for subportions of the video content, and receives the subportions via the local wireless network. The requesting UE aggregates the received subportions to obtain an alternate video portion for presentation and thus mitigate the predicted degradation of presentation quality. Other embodiments are disclosed.

  • Publication number: 20190342423
    Abstract: A content distribution network includes a first server in communication with an anycast server that provides content via a unicast signal, and with a multicast server that provides the content via a multicast signal. The first server is configured to receive a list of source addresses associated with the content, and to provide a metadata file including an anycast Internet protocol address of the anycast server from the list of source addresses as an Internet protocol address of the content in response to a first request for the content. When the number of client devices requesting the content exceeds a first threshold, the first server receives an updated list of sources including a multicast Internet protocol address of a multicast server, and provides the multicast Internet protocol address of the multicast server as the Internet protocol address of the content in the metadata file.

  • Patent number: 10470053
    Abstract: Aspects of the subject disclosure may include, for example, a guided wave launcher generates, in response to an output RF signal, a guided electromagnetic wave along a surface of a transmission medium, wherein the guided electromagnetic wave propagates along the surface of the transmission medium without requiring an electrical return path, and wherein the guided electromagnetic wave has a non-optical carrier frequency. A mismatch probe generates a mismatch signal based on the output RF signal, wherein the mismatch signal indicates an impedance mismatch of the guided wave launcher. A controller generates one or more control signals in response to the mismatch signal, wherein the one or more control signals adjust one or more adjustable circuit elements of an impedance matching circuit, wherein adjustment of the one or more adjustable circuit elements facilitates reducing the impedance mismatch of the guided wave launcher. Other embodiments are disclosed.
