- the printed circuit board on which the LSI for function expansion is mounted There is a problem that the total area of the substrates is increased by the area occupied by the function expansion substrate by further adding (hereinafter referred to as a substrate) to the device.

- a decoder for function expansion to reduce the size to a semiconductor chip size or an LSI package size.
- a manufacturer manufactures a digital television receiver by mounting a decoder and a tuner and a demodulator on separate substrates. Since the reduction in individual substrate area is at a limit in digital television receivers, it is difficult to further miniaturize the entire digital television receiver.
