Abstract
Systems and methods in accordance with various embodiments of the invention enable quality based streaming. A content player in accordance with an embodiment of the invention includes: a processor; a network interface; and memory containing a content player application. The content player application can direct the processor to: receive quality metadata describing a plurality of streams, where: the plurality of streams are encoded at different maximum bitrates; each stream is divided into content segments; and the quality varies between content segments in each stream. Furthermore, the content player application directs the processor to measure available bandwidth; request content segments from the plurality of streams based upon the available network bandwidth and the quality metadata, where the requested content segments include content segments encoded at a maximum bitrate and having quality that is the lowest maximum bitrate that achieves a target quality level.
