Abstract: Techniques are described for adaptive encoding different portions of media content based on content. Characteristics of GOPs of media content can be determined and used to set encoding parameters for the GOs. The GOPs can be encoded such that one GOP is encoded differently than another GOP if they have different characteristics.

Abstract: Techniques are described for server-side fragment insertion and delivery of media content. After receiving a request to play back media content, a manifest is generated that includes fragments associated with the requested media content and fragments associated with different media content. A client device requests fragments from a media server according to the manifest, and the media server provides the correct fragment in response to the request.

Abstract: Methods and apparatus are described for combining fragments of media content that correspond to multiple quality levels. A particular combination of fragments may be selected for a client device based, at least in part, on feedback received from the client device. In this manner, adaptive bit rate selection can be simulated for a client device that does not support adaptive bit rate selection.
