摘要

PROBLEM TO BE SOLVED: To provide a surveillance video image/voice recording/reproducing apparatus in a surveillance system for recording video image/voice data within an observed area, and allowing a user to visually check a speech information when recorded video data are reproduced in special modes such as high-speed reproduction or slow reproduction.;SOLUTION: When video image/voice data transmitted through a communication line 1 from each network camera is recorded on a hard disk 47, a voice analyzer 46 analyzes voice data in a reception voice buffer 44 with a voice-recognition algorithm and an impact sound judging algorithm, and generates a text information for utterance sound or a text information for "impact sound", as the result of recognition. A data recorder 45 associates the text information with video data in a reception video image buffer 43, and records it on the hard disk 47. Although voice is not reproduced at the time of video data reproduction in a special mode, the text information is displayed with the video image. Consequently, voice status in the reproduced video image can be checked visually.;COPYRIGHT: (C)2007,JPO&INPIT
