摘要： A recording/playback apparatus for a DVD on which a VOB and a management file of the VOB are recorded. When detecting a failure in the management file, the recording/playback apparatus changes the state of the DVD to: (a) a first state in which reading/writing of the DVD is available; (b) a second state in which reading/writing of the DVD is available but the VOB cannot be played back; or (c) a read only state, in accordance with the detected failure. When the state of the DVD changes to the second state, the recording/playback apparatus writes a new VOB onto the DVD. When the state of the DVD changes to the read only state, the recording/playback apparatus plays back the VOB recorded on the DVD.

摘要： A video frame is input to a spectrum analyzer, which transforms the frame from a spatial domain into a frequency domain. A resolution determiner analyzes the output of the spectrum analyzer, thereby selecting a resolution appropriate for the video frame. Then, a resolution converter converts a resolution of the video frame into the resolution selected by the resolution determiner. Thereafter, the video frame is subjected to a coding process by block divider, DCT transformer, quantizer and variable-length coder so as to be output as a coded bit stream. By coding the input video frame at a resolution corresponding to the high-frequency component in the frame, a video of higher quality can be obtained with the bit rate reduced.

摘要： A cumulative error D is calculated by sequentially adding up errors, each representing a difference between a given average target number Ba and a number Bg of bits generated during every predetermined period of a coded bit stream. In determining a number Bt of bits allocated to a compression coder, a provisionally allocated bit number Bst is preset based on a coding complexity X such that a number of bits allocated to a scene with a high coding complexity exceeds the average target number Ba as for a frame just after the change of scenes. And if the cumulative error D exceeds a predetermined value, the provisionally allocated bit number Bst is corrected in accordance with the magnitude of the cumulative error D so as to be reducible to, but not less than, the average target number Ba. As for frames within the same scene on the other hand, a previously allocated bit number Bt is sequentially updated such that the cumulative error D does not exceed a predetermined maximum value Dmax. Accordingly, even if a series of scenes with high coding complexities X appear consecutively, a number Bt of bits allocated to each of these scenes can always be at least equal to the average target number Ba, while the total number of bits generated can also be regulated. As a result, high image quality is ensured.
摘要翻译：通过依次相加错误来计算累积误差D，每个错误代表给定的平均目标数量Ba和编码比特流的每个预定时段期间产生的位数Bg之间的差异。在确定分配给压缩编码器的比特数Bt时，基于编码复杂度X来预设临时分配的比特数Bst，使得分配给具有高编码复杂度的场景的比特数超过平均目标数Ba，如在场景变化之后的一帧。并且，如果累积误差D超过预定值，则根据累积误差D的大小来校正临时分配的比特数Bst，以减少平均目标数Ba但不小于平均目标数Ba。对于相同场景中的帧，另一方面，先前分配的位数Bt被顺序地更新，使得累积误差D不超过预定的最大值Dmax。因此，即使具有高编码复杂度X的一系列场景连续出现，分配给这些场景中的每一个的比特数Bt总是可以至少等于平均目标数量Ba，而生成的总比特数也可以是规定。结果，确保了高图像质量。

摘要： An authoring system variously processes a bitstream carrying information about moving picture data, audio data, and subpicture data constituting titles having a sequence of related content, generates a bitstream constituting a title with content corresponding to a user selection, efficiently records the generated bitstream to a specific recording medium, and reproduces title content corresponding to a user selection from the bitstream thus generated. Editing content input by a user using a keyboard or other device for the multimedia bitstream content is the source data is converted to authoring encoding parameters. Whether certain conditions determined by the data structure and other considerations of the authoring system are met is determined, and if the conditions are not satisfied, feedback is given to the user to prompt re-entry of the editing information.
