Abstract
A media server in a home entertainment network allows a media rendering device to act as a digital media receiver. The media server enables trick mode functions such as scan forward or reverse, slow motion, pause, and seek on rendering devices with capabilities limited to 1× playback. The media server receives commands from user input at the rendering device transmitted over the network to the media server. The media server manipulates the media stream before transmission over the network by deleting or adding frames to the media stream as necessary to emulate the desired playback functions and replacing frame timestamps to create a media stream that appears to the media rendering device as a sequential 1× stream. The transmitted media stream may not contain all of the media content stored in the corresponding media file on the media server, thus avoiding limitations on the download bandwidth and local client storage.
