Patent attributes
A method performed by an apparatus provides for adaptive bit rate content delivery to one or more client devices. The method includes: receiving data presentation content encoded into a first data stream using a first set of encoding parameters, wherein the first data stream comprises a first plurality of frames corresponding to a first encoded bit rate, wherein each frame in the first plurality of frames includes as payload a portion of the data presentation content; receiving a request, for a client device, for a second data stream having a second bit rate that is lower than the first encoded bit rate; determining a first subset of the first plurality of frames, which corresponds to the second bit rate, and generating the second data stream using the first subset of the first plurality of frames, for delivering the data presentation content to the client device.
