Transmission terminal, transmission method, and recording medium storing transmission control program

1. A transmission terminal that communicates with a counterpart transmission terminal, the transmission terminal comprising:

a network interface configured to receive first content data from the counterpart transmission terminal, the first content data including first image data and first sound data, and to transmit second content data to the counterpart transmission terminal, the second content data including second image data and second sound data; and

a processor configured to detect a delay time indicating a delay in receiving the first content data from the counterpart transmission terminal, wherein, upon the detected delay time exceeds a predetermined value, the processor causes an imaging unit to interrupt capturing of the image of the object and further causes the network interface transmit, of the second content data, only the second sound data, to the counterpart transmission terminal.

2. The transmission terminal of claim 1 , wherein the processor causes the network interface to interrupt transmission of the second image data included in the second content data.

3. The transmission terminal of claim 2 , further comprising:

an imaging unit configured to capture an image of an object at the transmission terminal, wherein the image captured by the imaging unit is included in the second content data for transmission to the counterpart transmission terminal.

4. A method of controlling communication with a counterpart transmission terminal, performed by a transmission terminal, the method comprising:

receiving first content data from the counterpart transmission terminal, the first content data including first image data and first sound data;

detecting a delay time indicating a delay in receiving the first content data from the counterpart transmission terminal;

determining whether the detected delay time exceeds a predetermined value, wherein, upon determining that the detected delay time exceeds the predetermined value, a processor causes the imaging unit to interrupt capturing of the image of the object: and

transmitting, of second content data, the second content data including second image data and second sound data, only the second sound data, to the counterpart transmission terminal.

5. The method of claim 4 , wherein the transmitting step comprises interrupting transmission of the second image data included in the second content data.

6. The method of claim 5 , further comprising:

capturing an image of an object at the transmission terminal, wherein the captured image is included in the second content data for transmission to the counterpart transmission terminal.

7. A non-transitory recording medium storing a plurality of instructions which, when executed by a processor of a transmission terminal, cause the processor to perform a method of controlling communication with a counterpart transmission terminal, the method comprising:

receiving first content data from the counterpart transmission terminal, the first content data including first image data and first sound data;

detecting a delay time indicating a delay in receiving the first content data from the counterpart transmission terminal;

determining whether the detected delay time exceeds a predetermined value, wherein upon determining that the detected delay time exceeds the predetermined value, a processor causes the imaging unit to interrupt capturing of the image of the object; and

transmitting, of second content data, the second content data including second image data and second sound data, only the second sound data, to the counterpart transmission terminal.
