A method is provided for managing key rotation (use of series of keys) and secure key distribution in over-the-top content delivery. The method provided supports supplying a first content encryption key to a content packaging engine for encryption of a first portion of a video stream. Once the first content encryption key has expired, a second content encryption key is provided to the content packaging engine for encryption of a second portion of a video stream. The method further provides for notification of client devices of imminent key changes, as well as support for secure retrieval of new keys by client devices. A system is also specified for implementing a client and server infrastructure in accordance with the provisions of the method.

Method and system for secure over-the-top live video delivery

A software-defined media platform having one or more media processing units that may be dynamically instantiated, interconnected and configured according to changes in demand, resource availability, and other parameters affecting system performance relative to demand. In one example media processing method, a source media stream may be received via multicast or unicast. The source media stream may be processed into one or more levels of work product segments having different media characteristics by a plurality of transcoding processing units, as needed. One or more levels of work product segments, or the source media stream, may be packaged (e.g., including resegmenting) into final work product segments having select media characteristics, which may be uploaded to a cloud storage unit for delivery to end users.

Software-defined media platform

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.

A method is provided for performing targeted ad insertion in over-the-top delivery of content by detecting ad replacement opportunities in a live content stream and preparing the content for seamless replacement with segmented HTTP adaptive streaming delivery. The method includes provisions for multi-stage proxy-based segment replacement for targeted ad delivery. The method provided works transparently with standard HTTP adaptive streaming clients. A system is also specified for implementing a client and server content delivery infrastructure in accordance with the provisions of the method.
