Abstract: In some embodiments, a method generates a first representation of a first relationship between bitrate and quality based on first features of a first portion of a video. Also, the method generates a second representation of a second relationship between bitrate and quality based on second features of a second portion of a video. The first representation is analyzed to determine a first list of bitrates for the first portion of video and the second representation is analyzed to determine a second list of bitrates for the second portion of video. The first list of bitrates is different from the second list of bitrates. The method outputs the first list of bitrates for use encoding the first portion of video and the second list of bitrates for use encoding the second portion of video.

Abstract: A client (20A) receives streaming data according to Moving Picture Experts Group-Dynamic Adaptive Streaming over HTTP (MPEG-DASH) standard. The client (20A) includes a transmitter (202) which transmits a Media Presentation Description (MPD) request or a segment request to a server, and a receiver (201) which receives an MPD specified in the MPD request and a segment specified in the segment request. The MPD request contains information requesting transmission of an initialization segment by a push. The receiver (201) receives the initialization segment transmitted by the push.

Abstract: A method and apparatus for providing seamless failover to a redundant stream at an edge device is disclosed. A plurality of identical streams are received via a plurality of paths at a plurality of synchronization buffers. Each synchronization buffer receives one of the plurality of identical streams from a corresponding path of the plurality of paths. The plurality of streams are synchronized. A composite stream is generated from the plurality of identical streams according to a packet selection process.
