JP2000250595A - Sound-recording control system for ic memory - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent sound-recording contents of high importance from being erased by overwriting by discriminating between contents of high importance and contents of low importance in a received voice and performing control so that overwriting to only the contents of low importance is performed. SOLUTION: For example, general command contents A, B, and C are recorded in an IC memory in a receiver and the IC memory is full. The contents B are an emergency general command and information 1 indicating high importance is given. To record general command contents D newly, the contents A of low importance are erased and the new general command contents D are written. When the sound-recording time of the contents D is longer than that of the contents A, the contents C of low importance are erased and the rest of the contents D is written. The contents B given the information 1 indicating the high importance are so controlled that they are left as they are without being erased by overwriting. Consequently, the sound-recording contents of high importance can be prevented from being erased by overwriting at the time of the sound recording of the IC memory.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device which has an IC memory, records a received voice in the IC memory, and reproduces the voice when required.

[0002]

2. Description of the Related Art A conventional technique will be described with reference to FIG. For example, it is assumed that contents A, B, and C are recorded in the IC memory and the memory is full. The content B is a recorded content having high importance. When newly recording the content D, the content A is deleted and the new content D is written. If the recording time of the content D is longer than the content A, the content B is subsequently erased and the remaining portion of the content D is written.
As described above, the conventional recording method of the IC memory is overwritten regardless of the importance of the content to be recorded.

[0003]

As described above, the conventional I
The recording method of the C memory was overwritten irrespective of the importance of the contents to be recorded, so that extremely important contents were overwritten, and there was a problem that the contents could not be reproduced. The present invention
It is an object of the present invention to provide a recording control method for an IC memory that can prevent overwriting and erasing of highly important recorded contents.

[0004]

According to the present invention, in order to achieve the above object, information indicating the importance of a recorded content is added to a voice, and the voice received from the information has a high importance and a low importance. When discriminating the content and performing overwrite recording, control is performed so that overwriting is not performed on the recording content with high importance, but is overwritten only on the recording content with low importance. As a result, it is possible to prevent overwriting and erasing of the recorded content having high importance.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In the present embodiment, a receiver for receiving and recording a voice simultaneous command from a control station in a disaster management radio system will be described as an example.

[0006] Simultaneous commands in the emergency radio system are classified into ordinary simultaneous commands (low importance) and emergency simultaneous commands (high importance). One embodiment for recording these simultaneous commands will be described with reference to FIG. Simultaneous command contents A, B, and C are recorded in the IC memory in the receiver, and the IC memory is assumed to be full. The content B is an emergency simultaneous command, and information 1 indicating that the importance is high is added. Here, when newly recording the simultaneous command content D, the content A having low importance is deleted, and the new simultaneous command content D is written. If the recording time of the content D is longer than the content A, the content C having a lower importance is deleted and the rest of the content D is written. The content B to which the information 1 indicating high importance is added is controlled so as not to be overwritten or erased and to remain as it is.

[0007]

According to the present invention, it is possible to prevent overwriting or erasing of recorded contents having high importance during recording of an IC memory.
