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.

An audio encoder applies an adaptive block-encoding process to segments of audio information to generate frames of encoded information that are aligned with a reference signal conveying the alignment of a sequence of video information frames. The audio information is analyzed to determine various characteristics of the audio signal such as the occurrence and location of a transient, and a control signal is generated that causes the adaptive block-encoding process to encode segments of varying length. A complementary decoder applies an adaptive block-decoding process to recover the segments of audio information from the frames of encoded information. In embodiments that apply time-domain aliasing cancellation (TDAC) transforms, window functions and transforms are applied according to one of a plurality of segment patterns that define window functions and transform parameters for each segment in a sequence of segments. The segments in each frame of a sequence of overlapping frames may be recovered without aliasing artifacts independently from the recovery of segments in other frames. Window functions are adapted to provide preferred frequency-domain responses and time-domain gain profiles.

A dynamic image recording button and a still image recording button are provided at the main unit of a movie camera. A magneto-optical recording medium is loaded in a slot. If the dynamic image recording button or the still image recording button is operated during a reproduction operation, the reproduction operation is interrupted in a state in which the mechanical drive (rotation) of the magneto-optical recording medium is sustained. At this point, a dynamic image signal or a still image signal obtained through a photographing operation performed at the camera unit is temporarily recorded in a buffer memory, and is written in the magneto-optical recording medium when a write in the magneto-optical recording medium becomes enabled. Instructions to record dynamic images and to record still images can be issued to the movie camera through a touch-panel provided on the screen of a liquid crystal display unit. Even when operation cannot be performed through the touch-panel, the instructions can be issued through the dynamic image recording button or the still image recording button.

Automated creation of videos for interactive entertainment, such as video game highlights, may be based on events that occur within that entertainment, for example based on video game events. A series of events that can occur within a play session may be designated. The game keeps track of sufficient replay data such that these discrete events can be identified. Upon replay generation, the game searches over the historical data for that session and identifies the events that have occurred. The game may present several combinations of views of those events. For example, the game can create a highlights reel of the entire play session by linearly displaying several of the discovered events, or the highlights from several games can be selected by one or more individuals to generate a “highlights of highlights” video. Another embodiment allows the player, or group of players or other individuals, to choose which events to view. The events could also be categorized, allowing the player to view a collection of a selected event type, such as all flag capture videos or all long-distance shots.

When selecting a television program for recording, a user may configure the delivery of the selected television program and associated data and interactive applications to different user equipment devices in a home network, which may have different capabilities. Because the user equipment devices in the home network may have different capabilities, the user may wish to deliver different types and amount of content, different amounts of data, and different versions of interactive applications to the user equipment devices in the home network.

An automatic playback overshoot correction system predicts the position in the program material where the user expects to be when the user stops the fast forward or reverse progression of the program material. The invention determines the position where the program material was stopped. The media controller transitions to the new mode that the user selected, starting at the stopped position with an overshoot correction factor added or subtracted from it. The invention adapts to the user by remembering how much the user corrects after he stops the fast forward or reverse mode. Correction factors are calculated using the user's corrections and adjusting the correction factors if the user continues to make corrections. The invention also uses a prediction method to correctly place the user within the program upon transition out of either mode and determines if the speed of the fast forward or reverse modes and then automatically subtracts or adds, respectively, a time multiple to the frame where the transition was detected and positions the user at the correct frame. The time multiple is fine tuned if the user is consistently correcting after the fast forward or rewind mode stops. Another method initially tests the user's reaction time using a test video and asks the user to press the fast forward or reverse button on his control device during the test video and then asks the user to position the video to the place that he expected the system to have been. This time span is then used whenever the user uses the fast forward or reverse modes and is adjusted with a multiple for each speed. A final method allows the user to simply set a sensitivity setting that the system will use as a correction factor and a multiple is subtracted or added to the release frame whenever the user uses the fast forward or reverse modes, respectively.
