    Abstract: A system includes a processor and a memory. The memory stores instructions that, when executed by the processor, cause the processor to perform operations including sending a primary multicast video stream and a secondary multicast video stream to a media device. The secondary multicast video stream is limited to intra-coded frames (I-frames) extracted from the primary multicast video stream. Transmission of each intra-coded frame (I-frame) of the secondary multicast video stream is delayed with respect to transmission of a corresponding I-frame of the primary multicast video stream. The delay is based on an amount of writing time to satisfy a buffer threshold of a video content buffer at the media device to prevent a noticeable time shift of video displayed by the media device when the media device switches from outputting the secondary multicast video stream to outputting the primary multicast video stream.

    Abstract: A method includes sending a unicast transmission including at least a portion of media content to a media device in response to determining, at a media distribution computing device, that a request for a media stream to be provided to the media device does not indicate a scheduled recording of the media content associated with the media stream and joining the media device to a multicast group associated with the media stream without sending the unicast transmission to the media device in response to determining, at the media distribution computing device, that the request indicates the scheduled recording of the media content.

    Abstract: A system for resource provisioning for content delivery of multiple services is disclosed. The system may be configured to offer multiple services, wherein at least one first offered service is delivery of prerecorded content and at least one second offered service is content delivered according to a deadline. In at least one embodiment, the first offered service may be video content, and the second offered service may be broadcast television content. The system may also be configured to deliver at least a portion of the first offered service in advance of use of that portion of the first offered service such that resource demand in connection with delivery of service content of the second offered service at peak delivery may be reduced. As such, fewer resources are needed to provide uninterrupted service of the first and second offered services.

    Abstract: A method includes receiving, at a first node of a data network, a message indicating a failure of a communication link of the data network. The message is received at the first node from a second node of the data network. The method includes determining an alternate route from the first node to a data source of the data network. The alternate route includes a third node as an upstream node of the first node. The method includes determining whether the third node is a downstream node of the first node prior to sending a first join message from the first node to the third node, and sending the first join message from the first node to the third node conditioned on determining that the third node is not a downstream node of the first node.

    Abstract: A method includes forecasting demand for media content items of a media distribution system based on historical demand information to generate forecasted demand. The method includes generating a mixed integer program model based on storage constraints of a plurality of distribution nodes of the media distribution system, bandwidth constraints of the media distribution system, and the forecasted demand. The method includes performing a Lagrangian relaxation operation using the mixed integer program model. The method includes determining values of a cost function based on a result of the Lagrangian relaxation operation. The method includes assigning each of the media content items to a corresponding distribution node of the plurality of distribution nodes based on the cost function and the forecasted demand.
