Electronic toy receives control information via an input interface and stores the received control information in memory. In one aspect, a metal-oxide semiconductor device is provided comprising a substrate having a buried oxide layer at least a portion of which is configured to serve as a primary background oxygen getterer of the device; and a gate stack separated from the substrate by an interfacial oxide layer. The optical waveguide includes an input optical waveguide 21, branched optical waveguides 23 to 28, and an output optical waveguide 30. In this case, the receiving station can automatically issue a recording substitution request to the recording center station for substitution of the program recording.
