Abstract
An image data processor converts an image signal into an image data. The multi-codec unit converts the image data into a transfer data. A communication unit receives a transfer request from an outside terminal device and transmits the transfer data to the outside terminal device. A time-sharing control unit controls to drive the image data processor and the multi-codec unit in a time-sharing manner in accordance with the transfer request. A transfer data selecting unit for selecting the transfer data corresponding to the transfer request from a group of the transfer data generated by the image data processing unit and the multi-codec unit which are controlled to drive in the time-sharing manner by the time-sharing management unit, and transmitting the selected transfer data to the communication unit.
