  • Patent number: 10326701
    Abstract: Techniques for intelligent designated forwarder (DF) and master router selection (for router redundancy) are provided. In one embodiment, a network router that is part of a set of network routers connected to a common LAN segment can retrieve a priority value adapted for use by the network router in electing a DF for multicast traffic. The network router can further check for the presence or absence of one or more routes to one or more multicast sources in a routing table of the network router. The network router can then modify the priority value based on the presence or the absence of the one or more routes and can transmit a multicast routing protocol control packet including the modified first priority value to one or more other network routers in the set of network routers.

    Abstract: A system is proposed for delivering video content to display devices using a cloud computing model. A plurality of independent physical computer systems cooperate to implement a virtual computer system (“cloud”) which receives media content from sources of media content, and delivers the media content selectively to video display devices. For each of a plurality of users of the virtual computer system, there is a corresponding process (“cloudclone”) running on the virtual computer system which coordinates the delivery of the content to one or more of the video display devices which are associated with the corresponding user. The cloudclone includes respective components for managing the transfer of media content to each of the video display devices associated with the user. This makes possible a straightforward way of migrating video sessions between the devices associated with the user, by changing the corresponding cloudclone.

  • Patent number: 9015738
    Abstract: A video stream measurement method and system. The method includes receiving by a computing system, a video stream comprising plurality of timestamps located at specified intervals of the video stream. The computing system broadcasts the video stream for a user and decodes a first time stamp broadcasted during a first time period. The computing system monitors a user interaction function performed by the user and associated with the video stream. The computing system generates and transmits a report comprising a description associated with the user interaction function. The computing system receives an analysis associated with the report.

  • Patent number: 9009765
    Abstract: An object with embodiments of the present invention is to achieve a solution for fast channel change that improves bandwidth utilization, wherein the fast channel change is accomplished by initiating a unicast stream until a multicast stream can provide the desired media. The bandwidth utilization is achieved by delaying the multicast session and by terminating the unicast session at the latest when the multicast session starts. The delay of the multicast session is dependent on the network latency. Latency in this context refers to the time passed from when the client sends an IGMP JOIN message until it receives the first packet of the multicast stream.

  • Patent number: 9009771
    Abstract: In a video distribution apparatus, a memory caches segments of video data into which video data received from a communication network is sectioned on a basis of a predetermined unit and stores video identifying information of the segments of video data. A distribution controller derives, upon receipt of a cache distribution request from the network, video identifying information contained in a cache distribution request. A relay controller obtains segments of video data associated with the video identifying information from the memory to transfer the obtained segments of video data to a requester at a transfer rate defined on the segments of video data in the vicinity of a source of the video data. The video can be distributed at a transfer rate close to a transfer rate defined by a content distribution server while the video traffic can be diminished.

  • Patent number: 8990878
    Abstract: A system is described that consists of a variable modulation unicast system that utilizes multiple modulation schemes in a cable network for unicast applications and is capable of assigning users to different channels of differing modulation schemes in the network based on a feedback signal received in response to a transmitted probe signal. The system may also, in response to the feedback signal from a remote device in the network, assign a channel from a plurality of channels having differing carrier frequencies and modulation schemes to the remote device and may also modify the carrier frequencies of the channels.

  • Publication number: 20150082368
    Abstract: A system for presentation timing based audio video (AV) stream processing may include a switch device, a first processor, and a second processor. The switch device may be configured to route AV traffic to the first processor for processing and non-AV traffic to the second processor for processing. The first processor may receive transport stream packets that include an audio stream and/or a video stream. The first processor may receive a request to modify presentation timing of the audio stream and/or video stream. The first processor may modify the transport stream packets and/or presentation timing parameters of the transport stream packets based at least in part on the received request. The first processor may provide the transport stream packets to an electronic device. In some implementations, the second processor may be unable to access the content of the transport stream packets in the clear, e.g. due to security considerations.
