Abstract: The error detection code adding circuit adds error detection codes to watermark data. An encrypting circuit encrypts the error detection code added watermark data according to a first password. N encoders hide (embed) the encrypted error detection code added watermark data in the content data by N different hiding algorithms, respectively. A selector selects one of N encoders in response to a selection signal and outputs the encoded and selected content data in which the encrypted error detection code added watermark data is hidden. N decoders read watermark data and the error detection codes from the encoded content data by N extracting algorithms corresponding to the N hiding algorithms, respectively, to output N extracted content data including N read watermark data and N error detection codes and N read watermark data, respectively.

Abstract: Music-performance data is separated into at least note-number data, musical note-velocity data, musical note-length data and other necessary data. A primary encoded code is formed in which the note-number data, the musical note-velocity data, the musical note-length data and the other necessary data are arranged in different data fields. The primary encoded code and a playback player are compressed, the playback player being formed in software having a primary encoded code decoding function to decode the primary encoded code into the data arranged in the different data fields for reproducing the music-performance data, thus forming a first secondary encoded code for the primary encoded code and a second secondary encoded code for the playback player. The first secondary encoded code is decoded into the primary encoded code of the music-performance data. The second secondary encoded code is decoded into the playback player.

Abstract: A text analyzing section converts given text data into syllable data. A melody producing section receives the converted syllable data together with the text data and a standard MIDI file. The syllable data are assigned to a melody of the standard MIDI file and sent to a sequencer section. A software synthesizer converts the syllable data into vocal sounds with the interval variable in accordance the melody.

Abstract: A digital memory card includes a first area for storing a first file set having a set of audio objects and a second area for storing a second file set including a set of sound objects. A managing area is provided in the second file set and includes data for managing the first and the second file sets. Another memory card includes a first area for storing a set of sound files having a managing area, a second area for storing a still picture file and a third area for storing a motion picture file. The managing area stores data for managing the still picture and the motion picture files separately or together. The first and second file sets and the still picture and the motion picture files can be reproduced by a reproduction apparatus. Tune information is embedded in tune data as a digital watermark, the tune information being peculiar to the tune data. The tune information is further recorded in a file provided other than the tune data.

Abstract: In response to a "PAUSE RELEASE" command, a CD drive 1 resumes a playback operation earlier than the "PAUSE" position. The control module 2 analyzes whether continuity is recognized in the time information between a newly entered instruction and a finally processed instruction memorized in the memory 7. Graphic processing and development processing are canceled until the continuity is found. The image data developed in an internal memory 8 is transferred to an external memory 10 through a format conversion module 9. The control module 2 cancels a processing of the newly entered instruction when the newly entered instruction is either Soft Scroll Screen with Preset instruction or Soft Scroll Screen with Copy instruction having a scroll dot number smaller than a predetermined number. Alternatively, all the dot units scroll can be canceled while only the character units scroll can be performed.

Abstract: An original image signal is encoded into an image code signal of a predetermined format through an approximation process on colors. A first luminance component is derived from the image code signal. A second luminance component is derived from the original image signal. A difference between the first luminance component and the second luminance component is derived. The difference is converted into a luminance corrective signal. The image code signal and the luminance corrective signal are transmitted via a common transmission line. In a decoder, the luminance corrective signal is decoded to a luminance difference signal, which is added to an image signal decoded from the image code signal.

Abstract: In a MIDI signal processor, note on messages and note off messages are extracted from an input MIDI signal. A device detects that a first extracted note on message of a channel number and a note number is followed by a second extracted note on message of the same channel number and same note number without being followed by an extracted note off message of the same channel number and the same note number. The first note on message is outputted but output of the second note on message is inhibited when the detecting device detects that the first note on message is followed by the second note on message without being followed by the note off message.

Abstract: In a MIDI Signal processor, MIDI data is reproduced from a recording medium. The reproduced MIDI data is outputted. An interruption of the reproducing of the MIDI data is detected. A MIDI status byte is detected after the interruption ends. The outputting of the reproduced MIDI data is suspended when the interruption is detected. The suspending is continued until the MIDI status byte is detected.

Abstract: In a MIDI signal processor for use with a CD player, MIDI data is extracted from predetermined subcode frame of a digital output signal of the CD player. The extracted MIDI data is rearranged into a set of bytes. A predetermined start bit is added to a head of each of the MIDI data bytes. A predetermined stop bit is added to an end of each of the MIDI data bytes. The MIDI data bytes with the start and stop bits are outputted in a serial manner.
