Fast channel change in a multicast adaptive bitrate (mabr) streaming network using multicast repeat segment bursts in a dedicated bandwidth pipe

A system and method for effectuating channel changes in a multicast adaptive bitrate (mabr) streaming network using a dedicated bandwidth pipe for burst transmitting a requested channel's data. A video management agent is configured to stitch burst-transmitted data with the regular channel stream during the channel change to generate a hybrid stream, which is multicast streamed toward the requesting device. ...

Media distribution system with manifest-based entitlement enforcement

A method for enforcing entitlements includes configuring a wide variety of entitlements at a server; determining applicable combination of entitlements for a given client request; sending entitlements to the requesting client securely; handling entitlement information securely on a plurality of client devices at run time; storing entitlement information securely on a plurality of client devices for offline use; and enforcing entitlements on a plurality of client devices. The method employs manipulation of manifest files by a proxy that may be included in the client device or located in the network.. ... Ericsson Ab

Virtualization in adaptive stream creation and delivery

An adaptive streaming server, a method, and a system are described herein that create a content stream to be delivered to one or more clients by segmenting the content into data structures which are stored in random access memory (volatile storage) rather than segmenting the content into segment files which are stored on a disk or database (non-volatile storage).. . ... Ericsson Ab

Abr video white spot coverage system and method

A scheme for managing abr streaming of content in a wireless radio network environment that may have radio white spot areas. Upon determining that the wireless ue device executing an abr client application is in a radio white spot area, the current abr streaming session may be suspended at a particular segment. ... Ericsson Ab

Merging multicast abr and unicast abr with progressive download abr in a customer premises device within the same video delivery pipe

A method of managing bandwidth allocation across a video pipe that delivers both streaming adaptive bitrate (abr) content and progressive download abr content includes receiving a designation of a congestion boundary within a video pipe, the congestion boundary designating a first percentage of the video pipe that is to be used for streaming abr content when congestion exists on both sides of the congestion boundary, wherein a remaining percentage of the video pipe is to be used for progressive download abr; allocating bandwidth for streaming abr content, wherein the gateway device can allocate for streaming content only that portion of the remaining percentage of bandwidth that is not requested for progressive download content; and allocating bandwidth for progressive download content, wherein the gateway device can allocate for progressive download content only that portion of the first percentage of bandwidth that is not requested for streaming content.. . ... Ericsson Ab

Rendering content and time-shifted playback operations for personal over-the-top network video recorder

Live streaming video content is processed and stored for real-time delivery of the content, future vod viewing of the content, and time-shifted viewing of the content, by manipulating a common manifest or playlist. Previously stored content may be reordered and/or recombined in order to provide a personalized content viewing experience.. ... Ericsson Ab

Recording device space optimization in a multicast adaptive bitrate (mabr) streaming network

A system and method for managing recording quality and device space utilization in a multicast adaptive bitrate (mabr) streaming network. Using a subscriber recording schedule and available storage capacity, a dvr recording scheduler and optimization node is operative to determine a bitrate cap for one or more programs scheduled to be recorded at a default or target recording device. ... Ericsson Ab

Recording multicast adaptive bitrate (mabr) streaming content based on schedule

A system and method for facilitating recording of content in a multicast adaptive bitrate (mabr) streaming network using a dvr recording scheduler node. A program recording request may be generated at a subscriber device based on a program schedule to record a particular program, wherein the program recording request includes a priority level indicative of a video quality preference for recording the particular program. ... Ericsson Ab

Streaming policy management system and method

A streaming policy management system and method wherein bandwidth may be allocated based on external device information received from a streaming client device connected to one or more external audio/video (a/v) devices. When a streaming network back office receives a request from the streaming client device for delivery of a particular content, wherein the request includes external device information of one or more external a/v devices connected to the streaming client device, a bandwidth is determined for streaming the particular content to the streaming client device and a request may be made to a content delivery network to create a distribution pipe having the bandwidth to accommodate the delivery of the particular content. ... Ericsson Ab

Shifting of communication session charges

In accordance with certain embodiments, disclosed herein is a method for shifting charges. The method includes receiving a request for a communication session between at least two endpoints. ... Ericsson Ab

Entropy sharing in a large distributed system

Methods and apparatus for sharing entropy between an entropy broker and various devices are shown. The entropy broker receives a communication from a client. ... Ericsson Ab

Fast channel change in a multicast adaptive bitrate (mabr) streaming network using http download segment recovery in a dedicated bandwidth pipe

A system and method for effectuating channel changes in a multicast adaptive bitrate (mabr) streaming network using a dedicated bandwidth pipe for downloading a requested channel's data in a recovery segment by issuing an http request. A video management agent is configured to stitch the recovery segment's data with the regular channel stream during the channel change to generate a hybrid stream, which is multicast streamed toward the requesting device. ... Ericsson Ab

Fast channel change in a multicast adaptive bitrate (mabr) streaming network using multicast repeat segment bursts in a shared progressive abr download pipe

A system and method for effectuating channel changes in a multicast adaptive bitrate (mabr) streaming network using temporarily borrowed bandwidth from a shared progressive download abr bandwidth pipe for burst transmitting a requested channel's data. A video management agent is configured to stitch burst-transmitted data with the regular channel stream during the channel change to generate a hybrid stream, which is multicast streamed toward the requesting device. ... Ericsson Ab
