    摘要: A recording medium for storing virtual deletion information, and recording and/or reproducing method and apparatus therefor are provided. 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.

    摘要: A method of assigning a channel identification (ID) of an audio signal by which it is possible to follow up and select the audio channel selected by a user even though a program or an audio data stream is changed in an audio/video (A/V) device for reproducing a program including a plurality of audio data streams, a method of selecting audio channels using the same, and an apparatus suitable therefor. The method of selecting the audio channels of an A/V data stream including a plurality of programs, each program including at least two kinds of audio data streams, each audio data stream including at least two sub-audio data streams which are not repeated and having a series of IDs according to a predetermined order of precedence, the method including (a) when a program is changed to another program, searching whether there is a sub-audio data stream having a channel ID which is the same as the channel ID assigned to the sub-audio data stream of the program which was being reproduced before the program was changed, in the changed program, and (b) when it is determined that there is the sub-audio data stream having a channel ID which is the same as the channel ID assigned to the sub-audio data stream of the program which was being reproduced before the program was changed in the step (a), selecting the sub-audio data stream. According to the method of selecting the audio channels, it is possible to follow up a voice mode selected by a user (maintain the previously selected audio channel) although a program or an audio data stream is changed.
