Abstract
Systems and methods for performing a trick mode of video streams transmitted over a network without increasing the amount of data transmitted over the network. A video server transrates a source video stream to a target video stream by removing pictures from the source video stream. The target video stream has a reduced number of pictures compared to the source video stream. Therefore, when the target video stream is played on a display device, the target video stream has a playback speed faster than the playback speed of the source video stream.
