Abstract

An encoder resource receives segments of content on one or more data feeds. The encoder resource receives and/or produces encoder control information specifying multiple different bit rate data streams on which to encode the segments of content. As specified by the encoder control information, in accordance with encoding rules, the encoder resource adaptively encodes the segments of content into a varying number of different bit rate data streams. Clients in a network environment initiate retrieval of the varying number of different bit rate data streams to playback content.

IPC Classes  ?

  • H04N 21/2662 - Controlling the complexity of the video stream, e.g. by scaling the resolution or bitrate of the video stream based on the client capabilities
  • H04N 21/238 - Interfacing the downstream path of the transmission network, e.g. adapting the transmission rate of a video stream to network bandwidth; Processing of multiplex streams
