Patent ID: 8713336

Claim:
A display apparatus comprising: a receiving unit that receives from a communication apparatus, a confirmation message that confirms whether connections are to be established with the communication apparatus that transmits image data; a judging unit that judges whether the connections are to be established on the basis of an operation mode of an application program that runs on the display apparatus and that accesses information stored on the display apparatus or on the communication apparatus when the confirmation message is received; a generating unit that generates a reply message indicating whether the connections are to be established and responding to the confirmation message, on the basis of a judgment result made by the judging unit; and a transmitting unit that transmits the reply message to the communication apparatus, wherein the judging unit further judges, when a change is to be made to the operation mode, whether the connections are to be established based on an operation mode after the change, the generating unit further generates, when the change is to be made to the operation mode, a notification message that is notified during the connections being established to indicate whether the connections are to be established, based on a judgment result made by the judging unit, and the transmitting unit transmits the notification message to the communication apparatus before the change is made to the operation mode.
