Abstract: A signal control circuit and a signal control apparatus that can reduce processing time and can send or receive correct data with reliability. When a data generation block outputs data, a data judgment block judges the number of changed bits by comparing each bit of the data output in the preceding session with the corresponding bit of the data to be sent in the current session and outputs position information indicating the position of each changed bit and the number of changed bits when the number of changed bits has reached a predetermined level. An output control block keeps a time period for stabilizing the change in value of the bit corresponding to the position information when the data is output, and directs a data storage block to send the value of the bit corresponding to the position information to an external circuit after the kept period has passed.

Abstract: An information processor for controlling a storage device for storing content information, includes: a controller for receiving content information from the exterior and storing the content information in the storage device; and a generator for generating unique information that is unique to combination of the content information and the information processor through an operation of identification information of the content information and the information processor; wherein when the controller receives content information, the controller checks whether the content information includes information matching with the unique information and upon confirmation of both the information allows the content information to be stored in the storage device.
