Technologies are disclosed for providing stream media content and/or metadata indicating stream media content. A media control device may receive a Digital Living Network Alliance (DLNA) hypertext transport protocol (HTTP) request from a media content device. The DLNA HTTP request may have a header created by the media content device. The media control device may interpret the DLNA HTTP request header. A first metadata may be identified in the DLNA HTTP request header that may indicate a request for stream media content information. The media control device may send a DLNA HTTP response to the media content device. The DLNA HTTP response may have a header that may include a second metadata indicating the stream media content information. The second metadata may include information enabling construction of a HTTP Live Streaming (HLS) master playlist, a program map table, and/or a program association table associated with the stream media content.

Excess bitrate distribution based on quality gain in sabr server

A method and apparatus for predicting the software frame decoding time for an HLS variant bit stream based on measurements of the frame decoding time for the lowest bit rate variant given in the master playlist and acquired and played at initial session startup. This permits the determination of a maximum bitrate setting to be refined and applied at startup such that a media program player does not attempt to download and decode variants that might exceed its CPU capacity, thus preventing playback stalls and similar failures.

In embodiments of broadcast content to HTTP client conversion, a client converter receives video content as an input of broadcast content data streams from a content distribution system. The client converter can join a content data stream of the broadcast input, and convert the content data stream to unicast HTTP data, such as video content segments that are buffered for communication to a client device or to a media player of a client device. An HTTP server of the client converter can then communicate the unicast HTTP data to the client device or to the media player for playback of the video content.
