  • Patent number: 10085047
    Abstract: Methods and apparatus for selectively caching (and de-caching) video content in network so as to reduce content transformation requirements and also cache storage requirements. In one embodiment, a content caching controller associated with a content server differentiates content requests based on content attributes such as the requested codec format (e.g., MPEG or Windows Media), resolution, bitrate, and/or encryption type or security environment. If the content requested by a user is not available with the requested attribute(s), the content server transfers to content to the user by first transforming it. The content server also speculatively caches the transformed content locally, so that a future request for the same content with the same attributes can be filled by transferring without the intermediate transformation step. The controller allows the network operator to optimize use of available storage and transcoding resources.

  • Patent number: 9973785
    Abstract: A computer system receives two publishing streams from two multimedia recording devices for generating a playlist for streaming a live event. An ingest endpoint transcodes the publishing stream input into multimedia segments and uploads the multimedia segments to a data storage service. The multimedia segments from both publishing streams are evaluated to determine whether a failover event occurred that requires failing-over from a first publishing stream to a second publishing stream in order to generate the playlist. A playlist is generated, based on the evaluated multimedia segments, and includes Uniform Resource Identifiers for each multimedia segment of the live event. By using dynamic, on-demand playlist generation for input received on two publishing streams, the system is able to provide failover capabilities from a first stream to a second stream without the need for customer or viewer action.

  • Patent number: 9769536
    Abstract: The virtual broadcast system of the present invention optimizes the routing of digital content among nodes along overlay networks that are dynamically reconfigured based upon forecasts of frequently-changing congestion levels of component interconnections within an underlying network. In the context of delivering streaming video over the Internet to large numbers of concurrent users, the present invention makes efficient use of the limited capacity of congested ASN peering points by employing deep learning techniques to forecast congestion levels across those ASN peering points and, based on those forecasts, to optimize the routing of video content along dynamically reconfigured overlay networks. The virtual broadcast system handles unscheduled as well as scheduled events, streams live as well as pre-recorded events, and streams those events in real time with minimal delay in a highly scalable fashion that maintains a consistent QoE among large numbers of concurrent viewers.

  • Patent number: 9143813
    Abstract: A channel allocation mechanism for manages bandwidth using a channel profile to assure an available channel for supporting the highest expected bandwidth request by leaving a contiguous segment available to support such requests. Configurations discussed further below define a profile for expected media types, and associate each channel with a profile designating the media types assignable on that channel. Each media type includes a service and a bitrate, thus different formats of the same service (such as SD and HD) are distinguished. Each profile specifies a media type, and each channel is associated with one or more profiles. Further, a mapping of channels to associated profiles includes a reserve designation, indicating that other (unreserved) be fully assigned before assigning the reserved channels. The reserved channels provide a contiguous block of bandwidth, so that large bandwidth requests do not encounter assignment failure from a plurality of sparsely allocated channels.

    Abstract: The invention relates to a method and device for buffering data for multiplexing. The invention also relates to a method of multiplexing and to a multiplexer arrangement using the method and device for buffering data for multiplexing. In one embodiment the invention can be applied to the buffering of non-traffic data, such as firmware updates or other supplementary information, before multiplexing the non-traffic data with traffic data, such as television data of television channels, to form a satellite broadcast channel. In embodiments of the invention, non-traffic data for multiplexing is buffered and then read out again for multiplexing at a rate which is a function of buffer fullness. The non-traffic data may be multiplexed with at least one traffic data channel. A multiplexer can view the non-traffic data channel as another multiplexing input and can allocate the available bit rate between the traffic data channels and the non-traffic data accordingly.
