  • Publication number: 20190089996
    Abstract: Real-time metadata about a plurality of video streams, and information associated with a directed stream, is received. The information includes a plurality of time segments, where time segments correspond to a respective video stream selected by a director for display in the directed stream during the time segment. Additionally, it is determined, based on the information, that the directed stream will display a first video stream during a first time segment. Further, a subsidiary stream is generated for a first group of users. This involves determining to substitute a second video stream for the first video stream during the first time segment, based on real-time metadata and further based on a first set of rules associated with the first group of users. When the first time segment begins, the second video stream is outputted for display in the subsidiary stream.

  • Publication number: 20190082204
    Abstract: Embodiments provide techniques for delivering a paced stream of video data packets. One embodiment includes receiving a data stream of video data packets formatted according to a Society of Motion Picture and Television Engineers (SMPTE) standard. A desired rate of delivery for the video data packets at a gateway device is determined. Embodiments generate a padded data stream by inserting one or more pause frames in between the video data packets in the received data stream, based on the desired rate of delivery. The padded data stream is transmitted across a link to a network switch, to be transmitted to the gateway device.

  • Patent number: 10158973
    Abstract: Techniques in an information-centric network (ICN) for facilitating the transport of passengers or items are described. In one illustrative example, a first mobile device is configured to operate as a mobile transportation-offering ICN endpoint device. The first mobile device may connect to one of a plurality of fixed-location ICN nodes in the ICN network. The first mobile device may communicate in the ICN network one or more interest packet messages indicating an interest in a passenger or item to transport. The interest in a passenger or item to transport may be indicated in, for example, a Named Data Object (NDO). The one or more interest packet messages may include current transportation route information indicating a current anticipated route of transportation for a current passenger or item.
