Abstract
At a communication terminal, visual information reflecting an operation state of a candidate counterpart terminal and a graphical image that allows the communication terminal to switch from a first communications protocol to a second communications protocol, is displayed, respectively, when the communication terminal activates the first communications protocol. In response to a user instruction for selecting the graphical image, the communication terminal activates the second communications protocol to cause the communication terminal to communicate using the second communications protocol.
Claims17
A communication terminal, comprising:
- processing circuitry configured to activate one of a first communications protocol or a second communications protocol according to a user instruction, the first communications protocol to be used for transmitting at least video data based on a first call control protocol and a first video encoding format, and the second communications protocol to be used for transmitting at least the video data based on the first call control protocol of the first communications protocol and a second video encoding format different than the first video encoding format of the first communications protocol;
- a display controller configured to display, on a display, a destination selection screen to receive a selection of a candidate counterpart terminal from among a plurality of displayed candidate counterpart terminals, the destination selection screen including a selectable graphical image that, when selected, causes the processing circuitry to switch the communications protocol to be used for communication with the selected candidate counterpart terminal from the first communications protocol to the second communications protocol, when the processing circuitry activates the first communications protocol as a communications protocol to be used for communication with the candidate counterpart terminal;
- and
- a receiver configured to receive, while the destination selection screen is displayed, the user instruction for selecting the graphical image,
- wherein, when the user instruction for selecting the graphical image is received, the processing circuitry is configured to activate the second communications protocol to cause the communication terminal to communicate with the selected candidate counterpart terminal using the second communications protocol,
- wherein when the processing circuitry activates the first communications protocol, the communication terminal communicates image data based on the first communications protocol with the selected candidate counterpart terminal via a relay device, and, when the processing circuitry activates the second communications protocol, the communication terminal communicates at least the image data based on the second communications protocol directly with the selected candidate counterpart terminal and not via the relay device.

A method of controlling display at a communication terminal, comprising:
- displaying, on a display, a destination selection screen to receive a selection of a candidate counterpart terminal from among a plurality of displayed candidate counterpart terminals, the destination selection screen including a selectable graphical image that when selected, causes the communication terminal to switch the communications protocol to be used for communication with the selected candidate counterpart terminal from a first communications protocol to be used for transmitting at least video data based on a first call control protocol and a first video encoding format to a second communications protocol to be used for transmitting at least the video data based on the first call control protocol of the first communications protocol and a second video encoding format different than the first video encoding format of the first communications protocol, when activating the first communications protocol as a communications protocol to be used for communication with the candidate counterpart terminal;
- receiving, while the destination selection screen is displayed, a user instruction for selecting the graphical image;
- and
- activating the second communications protocol to cause the communication terminal to communicate with the selected candidate counterpart terminal using the second communications protocol,
- wherein when the first communications protocol is activated, the communication terminal communicates image data based on the first communications protocol with the selected candidate counterpart terminal via a relay device, and, when the second communications protocol is activated, the communication terminal communicates at least image data based on the second communications protocol directly with the selected candidate counterpart terminal and not via the relay device.

A non-transitory recording medium storing a plurality of instructions which, when executed by one or more processors, cause the one or more processors to perform a method of controlling display at a communication terminal, the method comprising:
- displaying, on a display, a destination selection screen to receive a selection of a candidate counterpart terminal from among a plurality of displayed candidate counterpart terminals, the destination selection screen including a selectable graphical image that when selected, causes the communication terminal to switch the communications protocol to be used for communication with the selected candidate counterpart terminal from a first communications protocol to be used for transmitting at least video data based on a first call control protocol and a first video encoding format to a second communications protocol to be used for transmitting at least the video data based on the first call control protocol of the first communications protocol and a second video encoding format different than the first video encoding format of the first communications protocol, when activating the first communications protocol as a communications protocol to be used for communication with the candidate counterpart terminal;
- receiving, while the destination selection screen is displayed, a user instruction for selecting the graphical image;
- and activating the second communications protocol to cause the communication terminal to communicate with the selected candidate counterpart terminal using the second communications protocol,
- wherein when the first communications protocol is activated, the communication terminal communicates image data based on the first communications protocol with the selected candidate counterpart terminal via a relay device, and, when the second communications protocol is activated, the communication terminal communicates at least image data based on the second communications protocol directly with the selected candidate counterpart terminal and not via the relay device.
