Abstract: An alternative design is presented and analyzed for providing a just in time video such that even though multiple variants are advertised to a client, the bit streams need not be present. Instead, the videos are generated just in time when a client requests them. At a given time instant, only that video stream is generated which corresponds to the bit rate requested by the client and streams with other bit rates advertised in the manifest file are not generated. This saves storage cost and/or lowers the numbers of transcoders needed to generate full manifest file all the time. Two different architectures are presented and analyzed. Analysis of impacts of the encoding/transcoding speed on the behavior of such a system is presented and used in designing an optimal solution based on desired price and performance points.

Abstract: Embodiments include a unified framework for minimizing congestion-dependent network cost by jointly optimizing forwarding and caching strategies that account for link congestion between neighboring nodes. As caching variables are integer-constrained, the resulting optimization problem is a non-deterministic polynomial time (NP)-hard problem. Embodiments relax the optimization problem, where caching variables are real-valued. Embodiments include optimality conditions for the relaxed problem. Embodiments include an adaptive and distributed joint forwarding and caching method, based on a conditional gradient method. Embodiments elegantly yield feasible routing variables and integer caching variables at each iteration, and can be implemented in a distributed manner with low complexity and overhead. Over a wide range of network topologies, simulation results show that embodiments have significantly better delay performance in the low to moderate request rate regions.

Abstract: The present disclosure provides systems and methods for interrupting streaming content provided via a manifest inviolate protocol. An intelligent streaming server or edge cache may substitute different content than that which is requested, without the client's knowledge. In some implementations, the client may request a first segment of a file or stream, and the streaming server may instead deliver a segment of an entirely different file or stream. The replacement segment may have the same length as the requested segment, and may be renamed such that the client believes that the requested segment has been properly served. Accordingly, without changing the manifest or departing from the requirements of the manifest-inviolate protocol and without changing any functionality of the client, a system may provide content switching on a per-segment basis, rather than a per-manifest basis.
