The following quote was obtained by the news editors from the background information supplied by the inventors: "This invention relates in general to over-the-top (OTT) media delivery and more specifically to managing multi-source streaming media.
"Content providers (CPs) typically create content (e.g., movies, television shows, webcasts, etc.) and license the distribution rights to network service providers, e.g., mobile network operators (MNOs) and multiple system operators (MSOs). There is a clear delineation between content production and content distribution in this model. The move toward Web-based delivery of content, over the public Internet, has shifted the paradigm for content delivery. Traditional service provider broadcast networks are being bypassed, and content publishers, content aggregators, and content service providers (all referred to herein as content providers) deliver content directly to consumers using generic data channels. This new paradigm, a non-broadcast, non-streaming approach which uses generic on-demand data connections rather than legacy multicast distribution infrastructure, is referred to as over-the-top or OTT delivery. OTT delivery affords greater control to CPs, but requires the CPs to manage content distribution. CPs may utilize content delivery networks (CDNs) to provide a distribution channel for OTT delivery. CDNs may be run by MNOs or MSOs, or by independent network service providers."
In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "Among the challenges faced by content providers in using content delivery networks (CDNs), one is the possibility that a given CDN may not have the necessary geographic footprint or network capacity to service all clients wishing to retrieve content. It may be necessary to employ multiple CDNs to adequately support content delivery. The management of these distribution channels requires new methods of interaction.
"Methods and apparatus are disclosed for managing a plurality of CDNs to optimize OTT content delivery to client devices. A workflow management system, referred to herein as a workflow manager (WFM), is responsible for managing the acquisition of source content from a content management system (CMS), preparation of the content, including, but not limited to, transcoding of the content into different encodings (e.g., different bitrates, frame rates, resolutions, sample rates, codecs, etc.), storing the transcoded content in different formats (e.g., 3GP, MP4, fragmented MP4, MPEG-TS, segmented MPEG-TS, RTP, etc.), and encrypting the different formats, so that the content is suitable for delivery to a plurality of client devices over a plurality of network infrastructures. The prepared content is then uploaded to a plurality of CDNs. Included are provisions for managing which content is distributed through a given CDN, and prioritizing which clients retrieve content through a given CDN.
"A method is provided for uploading content to a plurality of CDNs, managing delegation of delivery between CDNs, monitoring the performance of content delivery by each CDN, and providing clients with CDN retrieval information. A separate method is provided for client devices to measure and report the performance of content delivered, and manage the retrieval of content based on CDN performance metrics. A system is also specified for implementing a client and server infrastructure in accordance with the provisions of the method. The system includes a WFM server for preparing and uploading content to a plurality of CDNs. The system further includes a client for communicating with the WFM to determine where to retrieve content from and to provide feedback on CDN delivery performance.
