The conversion unit for reducing and converting the image data, the second control signal 3b from the control unit 3, 7 is a graph creation unit for creating a graph of the transmission order of the audio data, and 8 is the reduction output from the conversion unit 6. Image data and graph creation unit 7
An image memory for storing graphic data output from the display unit 9, a display unit for displaying the contents of the image memory 8, and a data storage unit 4 for receiving a third control signal 3c from the control unit 3.
A reading unit for reading out image data from the playback device 12 and sending it to the reproducing device 12 is a reading unit for receiving the fourth control signal 4d from the control unit 3, reading the audio data from the data storage unit 4, and sending it to the playing device 12. is there. In the reproducing device 12, 121 is an image memory for storing image data signals, and 122 is an image memory 121.
Is a FIFO for adjusting the time base timing of the audio data signal, 124 is a D / A converter, and 125 is an audio output unit.

The operation of the data editing apparatus configured as described above will be described below with reference to FIGS. 1 and 3.

First, FIG. 3 is an example of a screen displayed on the display unit 9. In FIG. 3, the screen is divided into an image data editing portion 31, a sound data editing portion 32, and an overall control portion 33 from the top. Of the image data editing portion 31, 313a to 313c are image data to be displayed on the playback device 12, 313b is the currently displayed image data, 313a is the previously displayed image data, and 313c.
Is image data to be displayed next. Characters 312a to 312c on the images 313a to 313c are file names corresponding to the respective image data. The image data 313a to 313c are stored in the data storage unit 4 with the file names 312a to 312c. The reading unit 5 reads these files from the data storage unit 4 and reduces them in the conversion unit 6 and then the image memory 8 And is displayed on the display unit 9. The arrow symbols 311a and 311c are symbols for controlling the image schedule. For example, when the arrow symbol 311c is selected using the mouse of the input unit, the image schedule advances by one, so the schedule storage unit 2 The content of is changed.
The control unit 3 reads the schedule storage unit 2 and gives a control signal 3a for the reading unit 5 to read the next image data from the data storage unit 4. The image data read by the reading unit 5 is reduced by the conversion unit 6 and displayed on the display unit 9 through the image memory 8. Therefore, the image displayed on 313c is
Move to the location of 313b, and the image displayed on 313b is 313a
Go to the location and see the following new image on 313c: If the image file names 312a to 312c are input from the keyboard of the input unit 1, the contents of the schedule storage unit 2 are changed, new image data is read from the data storage unit 4, and the display of the display unit 9 is changed. It

Further, the middle part of the image in FIG. 3 is the audio data editing section 32, which is displayed here on the premise of audio reproduction of 4 channels. 321a is the file name of the audio data file, and 321b graphically displays the position of the currently reproduced audio data with respect to the entire file. The arrows on both sides of 321b are used to move the position where the audio output is started. For example, when the arrow on the right side is selected with the mouse of the input unit 1 to advance the voice data, the contents of the schedule storage unit 2 are changed, and the control unit 3 sends the control signal 3b to the graph creating unit 7 according to this change and the graphic The data is changed and the display content of the display unit 9 is changed through the image memory 8. That is, the thick line at the center of the graphic data of 321b moves to the stone. Reference numeral 321c is a switch for outputting or not outputting audio data.

The lower part of the screen in FIG. 3 is the overall control part 33.
After the data transmission order is determined by the method already described and stored in the schedule storage unit 2, if the right arrow of the overall control unit 33 is selected to confirm the schedule, the schedule stored in the schedule storage unit 2 is selected. The control unit 3 reads and sends control signals 3c and 3d for reading the data file according to the schedule from the data storage unit 4 to the read units 10 and 11, and the read units 10 and 11 read The data is sent to the playback device 12 in real time. In this way, the schedule input from the input unit 1 is reproduced.
