A method is provided for managing over-the-top delivery of content through a plurality of content delivery networks (CDN). The method provided works transparently with standard HTTP servers supporting an initial request for content from a client to a first preferred CDN. If the first CDN does not have the content, the method includes provisions for the first CDN to acquire the content from a second CDN, or for the client to request the content from a second CDN directly. A system is also specified for implementing a client and server infrastructure in accordance with the provisions of the method.

Method and system for federated over-the-top content delivery

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 method and a user device are disclosed for securing streaming content decryption. The method includes receiving at the user device a manifest for requested content, the manifest providing a Content Encryption Key (CEK) that is encrypted using a first public Key Encryption Key (KEK), a corresponding first private KEK being stored in secure storage on the user device; decrypting, inside a secure processing zone on the user device, the CEK using the first private KEK to create a decrypted content key; decrypting, inside the secure processing zone, requested content using the decrypted content key to form decrypted content; and providing the decrypted content to a decoder on the mobile user device.

System and method for securing content keys delivered in manifest files

A traffic control system that controls mobile drive unit traffic within a facility by handling requests to traverse intersections based on a priority based in part on an order in which requests are received. For intersections with a directional bias, higher priority is given to requests having a direction of travel that aligns with the directional bias.

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.

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

A system and method for distributing content in an adaptive bitrate (ABR) streaming network. In one embodiment, an origin server receives an initial content request from a client device for a particular content, the client device operative with an ABR streaming media player. Depending on the information received in the initial content request, a local cache proximate to the client device requesting the particular content is located. The requested is then pushed to the local cache, whereupon a response message is generated to the client device, responsive to the initial content request, the response message including location information of the particular content with respect to the local cache.

Method and system for optimized media delivery

A method and apparatus for managing entitlements in a broadcast stream are disclosed. The method includes receiving a manifest containing program information for a program in the broadcast stream, with the program information providing a program entitlement block. The method uses entitlements specified in the program entitlement block to enforce entitlements for the program.

Program and device class entitlements in a media platform

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.

Method and system for ad insertion in over-the-top live media delivery

A method and system is provided for controlling bandwidth rate limiting and client rendering rate limiting in a video delivery network. The method provides network service providers with a means for overriding video delivery data rates selected through dynamic client bitrate adaptation, as well as video data rendering rates of the clients, to limit the impact of network congestion. A system is also specified for implementing a client and a proxy computer in accordance with the method. The system works transparently with standard HTTP-based video delivery systems and includes an HTTP proxy cache infrastructure to support bandwidth rate limiting and client rending rate limiting. The system further provides for administrative overrides of client bitrate selection and client bandwidth usage.
