Patent ID: 11006161

Abstract:
Approaches for generating dynamic over-the-top (OTT) adjustable bit rate (ABR) representations of a video with a variable resolution and/or frame rate using on-the-fly (OTF) transcoding and assistance metadata. At an encoder located at a head-end, the encoder encodes a video stream at an initial bit rate and produces optimum representation (OpRep) metadata, which describes an optimum presentation for the video stream for each of a plurality of bit rates or the minimum bitrate below which a presentation becomes sub-optimal. The head-end transmits the encoded video stream and the OpRep metadata to a transcoder of a Content Delivery Network (CDN). The transcoder at the CDN uses the OpRep metadata to dynamically transcode the video stream in a preferred picture resolution and a preferred frame rate at a different bit rate than the initial bit rate using the OpRep metadata.
