Abstract
Transfer control information for controlling a transfer amount per unit time of a transfer path is delivered from a transfer control section to an information transfer section. During encoding, the information transfer section receives image information from an external device in accordance with the transfer control information, and inputs the same to an image-information encoding/decoding section. A code-amount control section forwards code-amount control information for controlling the code amount to the image-information encoding/decoding section. The image-information encoding/decoding section encodes the image information in accordance with the code-amount control information outputted from the code-amount control section. The information transfer section transfers to an external device encoded information outputted from the image-information encoding/decoding section, while the transfer amount per unit time is being controlled by the transfer control section.
