Patent Number: 7,821,573

Title: Time setting system, imaging device, video-device, and time setting method

Abstract: An imaging device outputs video data with an image signal obtained from imaging an object, records video data onto a record medium, reproduces video data therefrom, outputs first time information from a clock section, communicates with another device through a first communication interface according to a predetermined protocol, and exchanges video data with the other device. A video-device automatically obtains second time information as reference from the outside of the video-device, processes a video signal, communicates with the other device through a second communication interface according to the protocol, and exchanges video data with the other device. When connected through the first and second communication interfaces, the video-device transmits the second time information to the imaging device. The imaging device receives the second time information and sets a time for the clock section with the received second time information.
