Abstract

Systems and methods of placeshifting media playback between two or more devices are provided. For example, a method for placeshifting media may include sending a first message from a media-receiving electronic device to a media-playing electronic device playing a media file and receiving a response identifying the media file and a point at which the media file was being played when the first message was received. The media-receiving electronic device may play a copy of the media file at the point where the media-playing electronic device left off.
