A television () includes: an image data receiving section () for receiving, from the outside, image data storing therein process specifying information; and a controlling section () for controlling an image processing section () so as to carry out a process specified by the process specifying information stored in the received image data. Thus, it is possible to cause the television () to carry out the desired process by causing the television () to receive the image data including the process specifying information for specifying the process which should be carried out by the television ().

Operating system that includes an image data receiving device and an operation device for processing image data sets

A digital optical transmitter includes a main/subdata modulation part for distorting a main data modulated signal waveform in response to sub-data, and an E/O conversion part for converting a subsequently obtained electrical modulated signal to an optical modulated signal and outputting the optical modulated signal. A digital optical receiver includes an O/E conversion part for receiving the optical modulated signal, converting it to an electrical modulated signal, and outputting the electrical modulated signal. Additionally, the digital optical receiver further includes a main/subdata demodulation part for demodulating the main data from the electrical modulated signal, while detecting whether or not a distortion signal responsive to the subdata is superposed on a subcarrier which forms the electrical modulated signal. If the distortion signal is superposed on a subcarrier, the main/subdata demodulator part demodulates the associated subdata.
