When power-off is instructed, a 1394 bus power source management section reads the value of a register of a link layer control unit circuit, and checks if a network device acts as a data transmission mediator. A video processing method to process video information of an image capturing device mounted on a moving body, includes detecting an analysis target from video information of images captured by the image capturing device, determining a status of the video information on the basis of information on the analysis target and outputting a result of the determination. The method may further include performing at least one of: processing a payment associated with the payment coupon to the biller based at least in part on the data extracted from the image; adding the biller to a list of billers for a payer associated with the payment coupon; or activating the biller as an electronic biller for the payer associated with the payment coupon. It also calculates for control the point of completion of compression from the history of compression performed previously. Also, the present invention is able to be utilized repeatedly. The coated electrode comprises a dry fibrillized polymer that is fibrillized with no processing additives.
