Abstract
A base station apparatus creates a synthesized moving image signal resulting from the synthesis of multiple moving image signals and encodes and converts the synthesized moving image signal to the encoded moving image signal and transmits the encoded moving image signal. In response thereto, a monitor apparatus extracts a moving image signal required by the monitor apparatus from the synthesized moving image signal obtained from the received encoded moving image signal. The extraction processing includes a transmission from the base station apparatus to each monitor apparatus and is implemented by the monitor apparatus based on extract command information having information details indicating a method of extracting a moving image signal from a synthesized moving image signal. Under the system configuration, one signal processing system is required for the encoding processing in the base station apparatus.
