A printer includes a communication circuit that communicates with an external device, a printing instruction receiver that receives a printing instruction, a controller that determines a printing amount based on a state of the communication with the external device, and a printing unit that executes printing based on the printing instruction and the printing amount.

Forward error correction is implemented in a facsimile transmission using adaptive redundancy. The depth of redundancy can change based on a number of factors, including lost packet counts, transport type, facsimile modulation type, call history or facsimile engine state changes. Separate redundancy depths can be implemented for image and for control phases of the facsimile call. Redundancy depth can be increased or decreased during a facsimile call, and may be maintained at an increased level once encountered transmission impediments are overcome. Variable redundancy can be provided for specific portions of the call, such as temporarily increased redundancy during control phases. Adaptive redundancy may be implemented at one or more endpoints or nodes in a packet-switched communication network through which the facsimile call passes. The adaptive redundancy contributes to improving successful facsimile call completion in communication networks that may be prone to error losses.

An image processing apparatus includes a reception unit configured to receive a session start message, a determination unit configured to determine whether the session start message received by the reception unit is a session start message from a public Internet Protocol network or a session start message from a local Internet Protocol network, an acquisition unit configured to acquire a media type included in the session start message received by the reception unit, and a control unit configured to determine whether a start of a session is allowed, based on a result determined by the determination unit and the media type acquired by the acquisition unit.

Provided is an image forming apparatus that allows a remote operation terminal to operate an image processing apparatus connected by SIP. On this account, the image forming apparatus (100) connected to the remote operation terminal (300) by SIP includes a remote operation-request message receiving part that receive a remote-operation request message from the remote operation terminal (300), a remote-operation response message transmitting part that transmits a remote-operation response message in response to the remote-operation request message, and an operation-screen information transmitting part that transmits operation screen information of the image forming apparatus (100) to the remote operation terminal (300) in accordance with the communication condition of the communication session when an SIP-based communication session is established between the remote operation terminal (300) and the image forming apparatus (100).

A method and apparatus for approving multimedia data, including: receiving second multimedia data of a second resolution; selecting a block of the second multimedia data; and requesting a corresponding block of first multimedia data, to the selected block of the second multimedia data. Furthermore, the method includes receiving the corresponding block of the first multimedia data of a first resolution; and approving the second multimedia data at the server apparatus in response to evaluating the received block of the first multimedia data.

To provide a mechanism in which a browser appropriately notifies a user of a change in the state without waiting for an instruction from a server and displays an appropriate operation screen upon reception of the instruction from the server in an information processing apparatus executing a process based on a request from the server. Upon detection of a change in the state, a service provider 340 notifies a Web browser 330 of the state and content information corresponding to the state. The Web browser 330 displays a screen in accordance with the content information included in the notification of the change in the state from the service provider 340. In addition, the Web browser 330 accesses an URL in accordance with an instruction from a Web server 102 to acquire an appropriate operation screen and displays the operation screen.
