Abstract

A video transmission apparatus that has a first input terminal for receiving a low-resolution TV signal. The apparatus also has a second input terminal for receiving a high-resolution TV signal and for outputting the high-resolution TV signal. The apparatus converts the low-resolution TV signal into a signal having a format which is equal to that of the high-resolution TV signal. The apparatus selects either the signal, which has been produced by converting low-resolution TV signal into a signal having a format which is equal to that of the high-resolution TV signal, or the high-resolution TV signal, which is outputted from the second input terminal. The signal which has been produced by converting low-resolution TV signal into a signal having a format which is equal to that of the high-resolution TV signal, is fitted into the high-resolution TV signal. The apparatus encodes the selected signal into a digital high-efficiency coded signal, and outputs a signal indicative thereof. Finally, the apparatus transmits the signal produced by encoding the selected signal.
