Abstract: An original stream file and an after-recording data file are managed as different files. In the original stream file, data is made up of sets of partial data (CU) divided in accordance with a predetermined interval. Likewise, in the after-recording data file, data is made up of sets of partial data (CA) divided in accordance with a predetermined interval. These sets of data are recorded onto a disc such that the after-recorded data (CA) is recorded in a region adjacent to a relevant original stream (CU). This allows reproduction and real-time after-recording with the use of a general MPEG-2 PS/TS decoder. Moreover, this allows realization of data recording that causes less interruption of reproduction when non-destructive editing is carried out with respect to an after-recorded result.

The number of minimum angle change units within the jump distance is calculated. The number of recordable angles is checked. The method is selected whereby the largest number of data items can be recorded consecutively on condition that the necessary number of angles is provided. This invention can be applied to recording/reproducing apparatuses.

Abstract: A “hold” feature on a user operated remote control allows a currently displayed track or view to be maintained while a video presentation is being played. As a user is watching a presentation that uses multiple camera views shown one-at-a-time as in a standard edited cut (i.e., “director's cut”) of a movie, the user can press a button when the user sees a camera view or scene of particular interest. Thereafter, the track associated with the camera view or scene that was showing when the hold button was pressed will continue to be played in place of the presentation. To return to the edited cut the user depresses the hold button again. The held track will continue to play until the user decides to resume presentation of the edited program or until the held track ends. Upon ending, the program track is resumed. While holding a track the user is free to select other available tracks in addition to jumping back to the program track at any time.

Abstract: According to an approach for storing digital content onto a DVD, digital content is received from a source, such as a DirecTV link, an over the air (OTA) broadcast, over a cable television link, or any other type of communications link, including the Internet. The digital content is formatted to comply with the MPEG standard to create MPEG digital content and stored on a non-volatile storage. Text-based information is received that describes one or more attributes of the received digital content. A set of DVD subpicture graphics is generated based upon the text-based information. The set of DVD subpicture graphics may represent a structure that can be navigated by a user when the DVD is played. The MPEG digital content is retrieved from the non-volatile storage, converted to DVD format and stored on the DVD with the DVD subpicture graphics.
