Abstract: Systems, methods, and computer products that facilitate transmission of information used for fast and responsive video and audio playback at non- standard, trick mode speeds. An embodiment of the present invention uses low resolution, compressed, and independent frames derived from the encoded digital video or audio information to facilitate the operation of user- requested VTR-like speed change functions associated with digital video and digital audio frames. The present invention greatly simplifies locating specific frames in a video or audio presentation for purposes such as fast forward and fast reverse scanning that is typically used in digital editing.
