Abstract: 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.

Abstract: An information recording medium and a reproducing method and apparatus are provided, so as to effectively update software in the reproducing apparatus. The information recording medium is provided with data and information for updating software stored in an apparatus which reproduces data from the information recording medium.

Abstract: A recording medium and a recording apparatus store manufacturer information to support specific functions for each manufacturer and a method therefore. A reproducing apparatus reproduces the manufacturer information to support specific functions. When the recording apparatus modifies the contents of the recording medium, the manufacturer's identification code is recorded. The recording apparatus and the reproducing apparatus checks the identification code on the recording medium before using its own manufacture information item for some specific function. Also, a time required to determine whether the manufacturer information items are effective is reduced.

Abstract: 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.

Abstract: An apparatus and method to record and/or read data on a recording medium including a master data processor to process a first type of data, a slave data processor to process a second type of data, and a multiplexer selecting one of interface signals outputted from the master data processor and the slave data processor to communicate with the disk driver. Additionally, the master data processor controls an operation of the slave data processor and the multiplexer to select one of the interface signals outputted from the master data processor and the slave data processor.

Abstract: A digital video recording apparatus is provided with the ability to permit a user to record images while watching those images without any time delay. The digital video recording apparatus includes an ADC for analog-to-digital converting and outputting either demodulated analog broadcast signals of a selected channel or analog AV signals inputted from an external device, an MPEG encoder for MPEG-encoding the ADC output in order to create stream data, a record-play unit for controlling so that data can be recorded onto or read from a recording medium, a background memory for buffering the stream data by a certain unit, and a controller for controlling so as to combine the stream data that is buffered in the background memory and the stream data that is encoded and created by the MPEG encoder subsequent to the buffered stream data, and to store the combined data into a recording medium, when a recording command is entered.

Abstract: A recording medium for storing information for still pictures, and a recording and/or reproducing method and apparatus therefor. A writeable and rewriteable recording medium stores data for a plurality of still pictures and audio data added thereto in one file or a space having a logically one-dimensional order, rather than in each file, and still picture group information for separating the still picture data into within a predetermined maximum number of groups in order to manage the still pictures at a group level is then stored on the recording medium. Thus, large-capacity still picture data and audio data added thereto can be recorded and/or reproduced using a minimum amount of information. The still picture group information includes general information for still picture groups, and information for still pictures in each still picture group.
