The object of the present invention is to provide a multimedia presentation device which, by executing a setting process for an information block, which is an address of an automatic branch, by means of an automatic discharge process for a button which stores the branch address, enables the user to understand how a branch address was selected. Command discharge condition information is stored the information block reproduction means for managing buttons which are automatically discharged at an end of a reproduction period or other such time, so that by executing a branch process by automatically selecting a button in place of a user operation, then even if there has been no user selection of a branch address before the end of the reproduction period, a branch address can be automatically selected and, by showing on the display the button which for manual selection stores a link to the same branch address, the data can be presented in a form which can readily understood by the user.

Multimedia data presentation device and editing device with automatic

A data editing apparatus includes a mass storage device to edit multimedia data such as picture, audio, text and other data. By the visual graphic display of the time positions of the edited information, the user can easily grasp the reproduction time of the picture, text and audio data, thereby simplifying synchronization of plural media data. Graphic editing may be effected to facilitate multimedia data editing.

Method of editing multimedia data including graphic display of

Information which must be continuously inputted or outputted in time, namely, audio and picture information, are inputted and outputted into a file apparatus as the digital data. Conventionally, the continuous inputting and outputting operations of the audio and the picture information and editing operations such as deletion, insertion and so on could not be made compatible and instantaneous. In the present technique an individual size is continuously stored into a storage media physically, and the input and output of the data and the storage reproduction with the storage media are effected in non-synchronization, with the size of an input/output buffer, a unit of an input/output of the audio and the picture information, and the unit of the editing being the same in size so as to realize instantaneousness and continuous input/output operations of the editing.

System with dedicated buffers connected to respective I/O devices for

Mass data is managed as data files in a mass data storage device. Each data file is formed or plural data blocks. Upon editing of a data file, the data content of each data block forming the file is examined. If the data content of a data block is less than a predetermined value, data from one or more adjacent data blocks is extracted and placed in the one data block so that the data content thereof will be at least the predetermined constant value. In this manner, the data content of blocks forming a file is maintained at or above a predetermined level.

Two level indexing method for accessing data blocks having first pointer

Information including pictures, sounds, and characters is inputted. A form of the inputted information is converted into a prescribed format in accordance with properties of the information, and thus converted information is derived. A first storage means holds the inputted information and/or the converted information. The information held in the first storage means is edited, and thus edited information is derived. A reproduction sequence is generated. A second storage means holds the edited information. The information held in the first storage means and/or the second storage means is reproduced in the reproduction sequence to allow a check on the information and the reproduction sequence. The information held in the first storage means or the second storage means is outputted for manufacturing a recording medium.
