摘要： A multicast content delivery system can use both multicast and unicast streams to efficiently use available bandwidth to deliver content. Available multicast content can be identified to gateways serving consumption devices, and the gateways can receive requests for unicast content deliver, but honor the requests with multicast group sessions.

摘要： A method and system optimally selecting antenna elements based on the current availability of antenna elements and the current usage of other antenna elements within a two or three dimensional array. The present system and method pertain to an approach to allow the maximal usage of each antenna element while simultaneously reducing the coupling between antenna elements to improve the signal strength in each antenna element by ensuring that antenna elements in the same incident path are not tuned to the same frequency or physically or electrically near elements tuned to identical or adjacent frequencies.

摘要： Systems, devices, and methods for streaming media content over a network are provided. One exemplary method of streaming media content over a network involves transmitting one or more portions of the media content to a client device via a delivery route between a content delivery source and the network, determining a performance metric associated with the transmitting of the one or more portions via the delivery route, and dynamically adjusting the delivery route between the content delivery source and the network based at least in part on the performance metric.

摘要： The invention relates to a method and apparatus for evaluating a network and for predicting network performance for a higher order modulation by analyzing network signals modulated using a lower order modulation format. A margin index may be generated for the current or projected modulation formats based on displacement vectors for received symbols to indicate a margin remaining before a codeword error occurs to alert the network operator of potential performance issues before actual codeword errors occur.

摘要： An example implementation includes a computer-implemented method including generating a dynamic user-interactable graphical interface using a performance summary including viewer traffic statistics for a first show and competing shows at discrete time intervals, the interface being configured to graphically display a comparison of performance of the first show and the competing shows at the discrete time intervals and provide the interface for display via on the user device. The method may also include receiving a user input selecting from the interface a time interval of the first show and the competing shows and updating the interface with the comparison of the viewer traffic between the first show and the competing shows at the time interval selected by the user input.

摘要： The present disclosure relates to a system and method for monitoring audio-video (AV) streams transported over a network. The system may include an AV probe deployed between an AV tuner and AV destination customer premise equipment. The AV probe may receive an incoming AV stream. The AV probe may generate a thumbnail stream by capturing thumbnails of the incoming AV stream. The AV probe may transmit, substantially in real-time, the thumbnail stream to a monitoring engine and the incoming AV stream to the AV destination customer premise equipment.

摘要： Systems, methods, and receiver devices enable broadcasters with restricted content license areas (e.g., Designated Market Areas (“DMAs”) to distribute content via Over the Top (“OTT”) IP networks. Embodiments enable client reporting and authentication as well as broadcast content encryption. In an embodiment, information from the client may be reported back to the broadcasters, such as a view history/use report. In an embodiment, hand off between DMAs may be enabled. In an embodiment, local advertisement insertion in network content may be enabled. Embodiments may enable Multicast-Broadcast Single Frequency Network (“MBSFN”) operation across DMA boundaries.
