摘要： A program information player automatically skips over any intermediate channel changes as a result of interrupting a prior recording of a selected program. The program information player includes a program sequence playback information generator. The program sequence playback information generator analyzes selected program identifier information and recorded program history log information and, in response, generates program sequence playback information without user intervention. The program sequence playback information includes a sequence of time stamp information associated with the selected program identifier information. According to one embodiment, the program sequence playback information directs memory to play back the selected program corresponding to the selected program identifier information by, for example, skipping over any intermediate channel changes. For example, the program sequence playback information may represent a read pointer in memory during playback.

摘要： A first set of display information is received at a device driver. The first set of display information indicates a portion of the video image to be displayed in a first window of a first monitor. An aspect ratio of the video image is determined based on the first set of display information. Based on the determined aspect ratio, the display driver determines a location on a second display device where the video image is to also be displayed.

摘要： A method and system for producing a single view video signal based on a multiview video coding (MVC) signal stream. A MVC signal stream representing multiple spatially related views of a scene, including a base view and at least one dependent view, is decoded to provide multiple decoded video signals representing the spatially related views, with respective portions of the MVC signal stream representing one of multiple temporally adjacent video frames, and the MVC signal stream representing multiple sequences of spatially adjacent video frames. The decoded video signals are processed to provide a processed video signal representing one of the spatially related views using image information from more than one of the decoded video signals. As a result, more image data is used during processing, thereby improving the spatial and temporal image quality.

摘要： Video is received at a standard aspect ratio. The video includes video content having an alternate aspect ratio. The video content is provided in a letterboxed format with black bars to make up the standard aspect ratio. The video is analyzed to identify portions of the video related to changing video content. A boundary for the changing video content is identified as the alternate aspect ratio. The alternate aspect ratio is then applied to the video to present the video at the alternate aspect ratio. Extraneous portions of the video, such as the black bars, are then discarded from the video to present the video at the alternate aspect ratio.

摘要： A system and method for providing playback of multiple video streams simultaneously is shown and described. A priority is assigned to individual windows of a plurality of windows used for playback of the video streams. A current window being accessed by a user is assigned a higher priority than nonactive, or background, windows. Playback characteristics, such as video resolution, transparency, and audio volume, are reduced in the playback of videos presented in nonactive windows in relation to video played in the active window. Accordingly, a user's attention may be drawn more to the active window than to the nonactive windows, while allowing the video and audio data in the nonactive windows to be provided to the user.

摘要： A mechanism is presented for editing a video stream as the stream is received, allowing real-time displaying and storing of the edited video stream without requiring the received video stream to first be recorded. The mechanism allows the selection of editing options prior to starting or during the record process. The mechanism can monitor the input video stream for specific characteristics and edit the video stream according to predefined editing options based on those characteristics and/or user inputs. Special effects can be intelligently selected based upon internal and external information about the video stream, for example, user actions, input source, and content information.

摘要： A method and apparatus provides for controlling presentation of multimedia content. In one example, the method and apparatus changes a display perspective of a multimedia presenting system that presents the multimedia content by determining an amount of display perspective adjustment based on a relative position between a user and the multimedia presenting system. According to the determined amount of display perspective adjustment, the method and apparatus issues one or more control commands that instruct the multimedia presenting system to change the display perspective. The display perspective may be changed for example by moving a display or portion thereof and/or by changing the perspective of the displayed image on the display while leaving the position of the display alone.
