Abstract: A communication apparatus includes a communication unit; and a control unit. The control unit performs control to cause a relay apparatus via the communication unit to request, from an external apparatus, second data for transmitting first data to the external apparatus. The control unit performs control to cause the communication unit to receive the second data from the relay apparatus. The control unit performs control to cause the communication unit to transmit the first data to the external apparatus without going through the relay apparatus based on the second data. The first data is communicated in compliance with a first communication protocol, and the second data is communicated in compliance with a second communication protocol. A communication compliant with the first communication protocol is less delayed than a communication compliant with the second communication protocol.

Abstract: The present invention enables an image selected by a user on the server side to be sent to a client in a client-server protocol. An image supply apparatus includes a storage unit storing images; a communication unit; and a processing unit that returns a response by performing processing in accordance with a type of a request received from a client. Here, the processing unit includes a display unit that displays, when a predetermined request is received, a list of images stored in the storage unit; a generation unit that generates, when a user has selected an image, information specifying the selected image for enabling the client to make a sending request for the selected image; and a sending unit that sends the generated information to the client as a response to the predetermined request.

Abstract: A communication apparatus which includes a communication unit that communicates with an external apparatus, records connection information for connecting to the external apparatus using the communication unit, and subjects, upon activation of the communication apparatus, the communication unit to communication connection to the external apparatus based on the connection information. The communication apparatus inhibits the communication connection to the external apparatus based on an activation factor, which is a factor in the activation of the communication apparatus.

Abstract: In a case where a recording medium having a communication function is used for a digital still camera, noise may be generated and superposed on data to be recorded if data transmission is performed in imaging. On the other hand, in a case where data is transmitted in response to a user's request from an external apparatus, communication interruption degrades usability. The digital still camera obtains a product name of the recording medium from the recording medium so as to specify a transmission mode. If an automatic transmission mode for spontaneously performing data transmission is specified, data transmission is interrupted when imaging instruction is issued and furthermore the communication function of the recording medium may be disabled. On the other hand, if a manual transmission mode for performing data transmission in response to a request is specified, a communication state is maintained even if an imaging instruction is issued.
