摘要： The erasion level appending range of a file is instructed. According to this instruction, the erasion level is set. 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.

摘要： A method and system in which a user manually changes the quality of portions of video frames after the frames have been previously encoded. Regions of one or more frames of video are selected to have an increased quality, a decreased quality, or a quality which should not be altered (174). After the regions are defined by a user, the frames of video is digitally re-encoded and inserted into the digitally encoded data stream in place of the previously encoded data (182 and 190). In order to easily remove a previously encoded frame from the data stream and replace it with a newly encoded frame having regions of quality defined by the user, it is preferable to have the newly encoded frame consume the same number of bits as the previously encoded frame.

摘要： 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.

摘要： A system (31, 41, 32, 33) in which a user manually changes the quality of specific time periods of encoded video (180). After the automatic encoding (50) of video into a compressed digital format, a person editing (31, 33) the encoded video reviews the quality of the video and manually indicates that the quality of specific time periods (180) of the video is to be altered. As the digital storage medium such as an optical disc (84, 90) which stores the encoded video has finite storage capacity, the total number of bits for the encoded video (50) and the quality of the video is limited. A percentage of bits are removed from time sequence and placed in a bit pool (368). Using an exponential function (368) new bits are calculated and the bits in the bit pool are proportionally distributed to the video frames (376). The frames must then be checked (394) and possibly adjusted (398, 400) to prevent underflow of the video buffer.

摘要： A method and system for re-encoding frames of a digital video stream without changing the previously calculated bit length of the stream. A set of macroblocks at a time are re-encoded (292), the number of resulting bits is calculated (306, 368) and the deviation from an estimated number of bits is calculated (372), either set-by-set or cumulatively. Based on the accuracy (372), of the estimate (422) and the remaining number of sets of macroblocks (424) to re-encode, a correction factor (710) for the quantization level of the next set of macroblocks is chosen from a lookup table. The correction factor is added to the quantization level of the next set of macroblocks (712) and the results stored as the new quantization level of the set (706). This sequential process is done for all sets of macroblocks in the digital stream which are to be recorded according to changed image qualities (706, 708, 710, 712, 714).

摘要： Audio information is recorded on an information medium in a format which is an expansion of the RTR (recording/reproducing DVD) standards. A 'cell for audio information' is defined as management information about information recorded on the information medium and as a reproduction unit for audio information similarly to the RTR standards. A PGC (program chain) at an upper level thereof has 'reproduction order' being the relation with other video information (movie cell) and/or still image information (still image cell).

摘要： In addition to normal subtitles, easy-to-see large letters, easy-to-read letters intended for children, and comments are available on the screen in the same language as that used in subtitles.
An optical disk has a management area and a data area. In the data area, main picture information, sub-picture information used to construct streams in different languages, and audio information have been recorded. In the management area, attribute information used to identify each piece of sub-picture information on the streams has been recorded. The attribute information includes language code indicating kinds of language. The language code is supplemented with a code extension indicating differences in the size of characters and/or description obtained from the sub-picture information. Sub-pictures include a stream of easy-to-see large letters and a stream of easy-to-read letters intended for children.-
