Abstract: In recording audio information, an information medium in a format obtained by expanding the RTR (recordable/reproducible DVD) standard is used. For management information about each piece of information recorded on the information medium, an “audio information cell” is defined as a playback unit even for audio information as in the RTR standard. To a PGC (program chain) higher in level than the cell, “playback sequence” information about the relationship between other video information (movie cells) and/or still picture information (still picture cells) is given.

Abstract: A white balance correcting device for correcting white balance by using video signals is arranged to be capable of accurately obtaining white balance even in a case where a picture includes only a small white part therein. The white balance correcting device is arranged to divide a picture into a plurality of blocks, to obtain a mean value of signals by averaging signals of each divided block as representing the block and a peak value of luminance from a signal having the highest luminance among others in each divided block also as representing the block, and to use, for white balance control, either the mean value or the peak value according to the state of the object of shooting.

When this setting range does not agree with the cell unit of the current cell, the current cell is divided to set a sequence of divided cells. Playback management information of each of the divided cells and current cell is re-created, and erasion level information is appended to playback management information of the divided cell that belongs to the appending range.

Abstract: A recording arrangement (1) for receiving and recording a television signal (F) and for receiving an information signal (I) which contains television program information (FPI), for example, title information about future television programs. The recording arrangement (1) has a keyword detector (54) which derives at least one keyword characteristic of the fields of interest of the user from title information of a television program recorded by the recording arrangement (1). A selector (58) selects, from the title information of future television programs, which is contained in the television program information (FPI), the title information containing at least one detected keyword. Selected television programs can be displayed on a display device (3) or can be recorded automatically.

The recording medium includes a first region having a plurality of still pictures, and a second region having first virtual deletion information for the still pictures, and still picture group information for separating the still pictures in the first region into a predetermined maximum number of groups in order to manage the still pictures at a group level, wherein the first virtual deletion information is within the still picture group information, and if the first virtual deletion information is set to a virtual delete state, the corresponding still picture is not to be reproduced. Accordingly, file extent information can be prevented from excessively increasing by maximally preventing a recording area from being scattered, when some of a data file are deleted by a user's request.

Abstract: A digital video disk player having a quick playback function and a method of reproducing an optical disc using the digital video disk player. The quick playback function is accomplished by analyzing reproduction control information and searching the titles corresponding to a predetermined title, calculating the running time of each title based on the video title information corresponding to the searched titles, and reproducing the selected title on the basis of the calculated running time. Accordingly, a selective reproduction of a title corresponding to a main movie among a plurality of titles recorded on the disk can be performed.

Abstract: The invention relates to a data structure and operation method for A/V (audio/video) disks. The specification disclosures a type of navigation files with a new structure. This navigation file utilizes a plurality of tables with different data types to record data relevant to another A/V file in the disk. To distinguish different data types of tables, each table has a table head and a table serial number. There is also an erase/modify information table in each of the data types to record editing information that has been done (such as editing information of erase/modify). Any newly created or edited table is written to a disk by appending. When first using an A/V player to play A/V data, all the tables are combined into a navigation file through the steps of separating tables, modifying tables and rearranging table. Thus, newly created or edited A/V data in an A/V disk can be played without the need to modify the original navigation file in the disk.

Abstract: A video signal processing apparatus, a video signal playback apparatus, and a video signal recording apparatus are presented for preventing illegal copying of thumbnail images. For example, a thumbnail encoder generates a thumbnail image of a video signal input from a terminal. A macrovision detector, a CGMS detecting/updating unit, and a WM (watermark) detecting/updating unit detect an analog copy protection signal (APS), a CGMS signal as copy generation management information, and watermark, respectively, of the video signal input from the terminal, and outputs them to a controller. The controller generates copy control information of the thumbnail image based on the input copy control information. The thumbnail image and the copy control information thereof are recorded in an information recording medium. This may be applied to a recording apparatus for recording data into an information recording medium and to a playback apparatus for playing back data recorded in an information recording medium.

Abstract: A video editing system uses simple heuristics and parameters on video footage to provide a condensed version of the footage. The editing system automatically provides either a finished condensed version of the footage or selects a plurality of clips based on the heuristics and parameters. The clips are optionally further edited by a user to produce a condensed version. The condensed version is transferable to any desired media suitable for storing video. A user interface enables the user to select heuristics to identify video clips from the footage. Parameters are also be set to automatically edit the clips in a desired manner. Temporal combinations of heuristics and parameters form templates, which are used to assemble desired clips for selected types of events.
