Provided is a system for identifying vehicles of traffic violators, the system having elements that include: a video camera for providing, in real-time, a video signal that represents plural sequential video image frames (either perceptually continuous video, such as 30 frames per second, or non-perceptually continuous video, such as 1-2 fps); a traffic violation detector (e.g., a radar gun, an in-ground loop, a pair of self-powered wireless transponders or transmitters, a camera-based speed detection system, or any other speed sensor) that provides a trigger signal (e.g., based on vehicle speed and detection of the state of a traffic signal); a video recorder that receives the video signal provided by the camera and records the video signal in a buffer until receipt of a trigger signal, at which point at least a portion of the video signal stored in the buffer is preserved for recording and direct real-time storage of the video signal to a hard drive, or other high-capacity storage medium, commences. As a result, the video signal is preserved during a pre-programmable sliding (or rolling) time interval prior to provision of the trigger signal.

A multimedia program bookmarking system provides a bookmark function that allows the user to bookmark a program where he left off. The invention records the frame of the program where the user stopped when the user commands the system to do so. Alternatively, the invention automatically bookmarks the program for the user if the user exits viewing the program. The invention displays an indicator indicating that a bookmark has been saved and the user can, at any time, access his bookmark and continue playback of the program from where he left off. Bookmarks within a single program can be set for different users. Remote controls are encoded for a specific user in a household, allowing each person in the household to have a personal remote control and therefore, personal bookmarks. The invention notes that a set of bookmarks belongs to a certain encoded remote control. The user can alternatively select a specific set of bookmarks manually, through a menu. The system loads the associated bookmark information for the user and any bookmarks that do not have associated programs stored on the storage device are ignored and deleted, otherwise programs are played backed starting from the associated bookmarks, if they exist. Multiple bookmarks for a program are transparent to the user because the remote control that the user uses tells the system to only display and activate that particular user's bookmarks.

A media player may occasionally be unable to play or continue to play a particular item of media. When that occurs, the media player outputs an error indication that is related to the type of media that the problem media item is representative of. For example, if the problem item is a movie, then the media player may display an error indication having the appearance of broken movie film. If the problem media item is music, then the media player may display an error indication having the appearance of a broken compact disc (“CD”). Thus whatever the type of media that is not playing, the media player outputs an error indication that is appropriate for that type of media. The error indications output by the player are therefore context-based or media-appropriate.

A graphical user interface for a computer-assisted motion video editing system directs a user through the process of editing a video program. The graphical user interface may also enables a user to plan a video program. Alternatively selectable interfaces within a single window interface, each of which provide a group of planning, capturing, editing, and recording functions can provide such an interface for producing a video program. Other simplifications to the user interface can be provided to assist in editing, such as by maintaining a video display window for displaying the edited video program at a fixed position for all available editing operations. Additionally, video information can be captured directly into a timeline representation of a video program, rather than a bin. Using a storyboard tied to the capturing process, a user is directed through the process of collecting and capturing the video clips to be used in the video program.
