Described herein is a technology for the presentation of digital video. One implementation, described herein, smoothly presents variable-speed scanning of a compressed digital video stream&#x2014;for example, a MPEG video stream. One implementation, described herein, smooth scanning (e.g., fast-forward and fast-rewind) video is produced by selectively displaying certain types of frames of a Group-of-Pictures (GOP). The scope of the present invention is pointed out in the appending claims.

Smooth scanning presenter

An arbiter component receives a request from a media control object for control of a media resource. The arbiter determines whether a media resource is available, and if a media resource is available, forwards the request to the available media resource. The control object may lock control of the media resource to maintain control of the media resource until the media control unlocks control of the media resource.
