Abstract
An information collecting system includes at least one terminal and an application server. The application server includes a receiving section for receiving input information transmitted from the terminal to the information processing center via the network; an information processing section for deciding as to the information received, and for constructing a picture to be displayed on the terminal in response to a decision result; and a transmitting section for transmitting the picture generated by the information processing section to the terminal. The application server further comprises a differential detector for detecting a difference between the client display picture stored in a storage and a client display picture newly generated by a client display screen constructor, wherein said transmitting section transmits only differential information detected by said differential detector to said terminal.
