PROBLEM TO BE SOLVED: To solve the problem that sound information which is not permitted to copy without the consent of a copy right owner can be copied onto a memory card with a comparatively high sound quality when recording voice information collected by a microphone of a high sound quality to the memory card in a digital video camera provided with an attachable/detachable memory card, etc. SOLUTION: In the case of recording a sound signal in the memory card 117, a switch means 113 selects the side of a terminal B to restrict the voice signal (band restriction by an LPF 112, the reduction of sampling frequencies, the reduction of the number of quantization bits, e.g.). Thus, sound information which is not permitted to copy without the consent of a copyright owner is prevented from being copied onto the memory card with the comparatively high sound quality. |
