信機。[Scope of claim for utility model registration] A current standard television system signal with a different aspect ratio from a high-definition television system signal,
In high-definition television receivers that have means to display images on the screen of a high-definition display that is compatible with the high-definition television system, the current standard television system signal is based on the vertical length of the high-definition display screen. A signal conversion device that converts the current standard television signal into a high-definition signal further converts the high-definition signal into a high-definition signal by using a portion of the current standard television system signal to provide a supplementary signal that fills the horizontal period that is insufficient in the current standard television signal. A high-definition television receiver characterized by being provided with means for adding.
