Abstract: An entire stream containing a plurality of partial streams each consisting of content information is multiple-recorded on packet basis on an information recording medium. The information recording medium includes a file for storing object data consisting of a plurality of packets each containing a content information piece and further includes a file for storing information defining a reproduction sequence of object data and information indicating discontinuity of continuous numbers caused by absence of a packet during edition of continuous numbers of a plurality of packets corresponding to the recording order during multiple recording.

Abstract: An information recording medium includes an object data file for storing object data as a series of content information such as video information and audio information and play list information file for storing play list information defining a reproduction sequence on play list basis. Furthermore, the medium includes a disc information file for storing a plurality of title play lists each containing information specifying play list information defining a play list to be reproduced, pre-command information and post-command information specifying commands to be executed before and after a reproduction, respectively, according to the play list information.

Abstract: An information recording apparatus (S) is provided with: first format recording device (125) for recording an image information on a recording medium in first format; and second format recording device (125) for recording the image information on said recording medium in second format that is different from said first format.

Abstract: On an information recording medium, an entire stream including a plurality of portion streams, each of which is provided with a series of content information, such as picture information or video information and audio information, is multiplexed-and-recorded by a unit of packet. The information recording medium is provided with a file for storing object data, which is provided with a plurality of packets, each of which stores therein a piece of the picture information or the audio information.

Abstract: An information recording medium is provided with: a file for storing object data which constitutes a series of content information, such as picture information or video information and audio information, and a play list information file for storing play list information which defines a reproduction sequence of the object data by a unit of play list. The information recording medium is further provided with a disc information file for storing a plurality of title play lists including information for specifying the play list information which defines the play list to be reproduced, Pre command information and Post command information, which indicate commands to be executed before and after the reproduction, respectively, based on the play list information.

Abstract: An information editing apparatus for editing recording information already recorded on a write-once recording medium such as DVD-R is provided. In this apparatus, a remaining capacity in the DVD-R is detected. Then, it is determined whether the recording information can be edited or not on the basis of the detected remaining capacity and an amount of information to be recorded in the unrecorded area by editing the recording information. Further, a result of the determination is notified.

Abstract: On an information recording medium, an entire stream including a plurality of portion streams, each of which is provided with picture information or audio information constituting a series of content, is multiplexed-and-recorded by a unit of packet. The information recording medium is provided with a file for storing object data, which is constructed by a plurality of packets, each of which stores therein a segment of the picture information or the audio information. The information recording medium is further provided with a file for storing information which defines a reproduction sequence of the object data and a file for storing information which defines a group having a specific relation from among a plurality of the plurality of portion streams.

Abstract: Provided is an information recording apparatus which, in a state where the content of moving picture image information, etc. can be prevented from being inadvertently recognized by the user due to inadvertent presentation to the user of a relevant representative picture image, enables recording the respective information into a recording medium. A reproduction list PL that is to be reproduced is not only recorded into an optical disc 1 but is there also recorded in it a reproduction list display prohibition flag PHF indicating at least whether limiting the display of a representative picture image that represents the content of the reproduction list PL.

Abstract: Information file recording method and apparatus are devised to have high recording efficiency. In parallel with the recording of an information file on a recording medium, file management data relating to the information file is once recorded in a memory. The file management data is retrieved from the memory and recorded in a predetermined area of the recording medium.
