Communication control system, communication control method, communication control program, terminal, and program for terminal

A terminal comprising:

• a signal transmitting unit configured to transmit a transmission signal containing at least one of a voice signal and a video signal to an other terminal;
• a storing unit configured to store the transmission signal in association with information indicating each part of the transmission signal into a memory unit;
• an acquisition unit configured to acquire response information indicating an arrival part of the transmission signal received by the other terminal among the transmission signal from the other terminal;
• and
• a display unit configured to display information transmitted by the transmission signal in chronological order in such a way that a lost part of the transmission signal not received by the other terminal among the transmission signal is identifiable based on the information indicating each part of the transmission signal and the response information.

A communication control method by a terminal that communicates with an other terminal, comprising:

• transmitting a transmission signal containing at least one of a voice signal and a video signal to the other terminal;
• storing the transmission signal in association with information indicating each part of the transmission signal into a memory unit;
• acquiring response information indicating an arrival part of the transmission signal received by the other terminal among the transmission signal from the other terminal;
• and
• displaying information transmitted by the transmission signal in chronological order in such a way that a lost part of the transmission signal not received by the other terminal among the transmission signal is identifiable based on the information indicating each part of the transmission signal and the response information.

A non-transitory computer readable medium having a program for a terminal causing the terminal to:

• transmit a transmission signal containing at least one of a voice signal and a video signal to an other terminal;
• store the transmission signal in association with information indicating each part of the transmission signal into a memory unit;
• acquire response information indicating an arrival part of the transmission signal received by the other terminal among the transmission signal from the other terminal;
• and
• display information transmitted by the transmission signal in chronological order in such a way that a lost part of the transmission signal not received by the other terminal among the transmission signal is identifiable based on the information indicating each part of the transmission signal and the response information.
