20120240176 | METHOD AND SYSTEM FOR FEDERATED OVER-THE-TOP CONTENT DELIVERY - 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. | 09-20-2012 |
20120265892 | METHOD AND SYSTEM FOR SECURE AND RELIABLE VIDEO STREAMING WITH RATE ADAPTATION - A system for media delivery includes a server-side proxy for aggregating and encrypting stream data for efficient HTTP-based distribution over an unsecured network. A client-side proxy decrypts and distributes the encapsulated stream data to client devices. A multicast-based infrastructure may be used for increased scalability. The encoded rate of the media delivered over the persistent HTTP proxy connections may be dynamically adapted. The client-side proxy may be integrated within a mobile device for maximum network security and reliability. | 10-18-2012 |
20120331293 | METHOD AND SYSTEM FOR SECURE OVER-THE-TOP LIVE VIDEO 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. | 12-27-2012 |
20130097309 | METHOD AND APPARATUS FOR CARRIER CONTROLLED DYNAMIC RATE ADAPTATION AND CLIENT PLAYOUT RATE REDUCTION - 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. | 04-18-2013 |
20140047069 | METHOD AND SYSTEM FOR FEDERATED OVER-THE-TOP CONTENT DELIVERY - 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. | 02-13-2014 |
20140149210 | METHOD AND SYSTEM FOR AD INSERTION IN OVER-THE-TOP LIVE MEDIA DELIVERY - 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. | 05-29-2014 |
20140150019 | METHOD AND SYSTEM FOR AD INSERTION IN OVER-THE-TOP LIVE MEDIA DELIVERY - 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.
