Alternatively, the live video communication will be extended beyond the pre-set time period if a request to extend the live video communication is received from one of the two terminals. ## Claims ### Claim 1 A method for live video communications, comprising: bridging a live video communication between a first terminal and a second terminal by a server device which comprises one or more processors and memory storing instructions to be executed by the one or more processors to bridge live video communications; setting a pre-set time period ranging from 1-15 seconds; and extending the live video communication beyond the pre-set time period upon a condition that a request to extend the live video communication is received from the first terminal or the second terminal, before the pre-set time period has elapsed since the live video communication started; or terminating the live video communication upon conditions that the pre-set time period has elapsed and no request to extend the live video communication is received from the first terminal or the second terminal, before the pre-set time period has elapsed since the live video communication started. ### Claim 2 (depends on 1) The method of claim 1, further comprising: before bridging the live video communication, rendering availableness description of the first terminal for the live video communication to the second terminal. ### Claim 3 (depends on 2) The method of claim 2, wherein the availableness description of the first terminal comprises information on environment the first terminal is in. ### Claim 4 (depends on 2) The method of claim 2, wherein the availableness description of the first terminal comprises information on location the first terminal is in. ### Claim 5 (depends on 1) The method of claim 1, further comprising: before bridging the live video communication, rendering request description from the second terminal for the live video communication to the first terminal. ### Claim 6 (depends on 5) The method of claim 5, wherein the request description from the second terminal comprises a description about the live video communication to the first terminal. ### Claim 7 (depends on 1) The method of claim 1, wherein rendering an indicator that the live video communication is going to be terminated to the first terminal or the second terminal, before the pre-set time period has elapsed. ### Claim 8 (depends on 1) The method of claim 1, wherein rendering an indicator that the live video communication is going to be terminated to both of the first terminal and the second terminal, before the pre-set time period has elapsed. ### Claim 9 (depends on 1) The method of claim 1, wherein the pre-set time period ranges from 1 to 10 seconds. ### Claim 10 (depends on 1) The method of claim 1, wherein the pre-set time period ranges from 1 to 30 seconds. ### Claim 11 A method for live video communications, comprising: bridging a live video communication between a first terminal and a second terminal by a server device which comprises one or more processors and memory storing instructions to be executed by the one or more processors to bridge live video communications; and terminating the live video communication upon a condition that a pre-set time period has elapsed since the live video communication started, wherein the pre-set time period ranges from 1 to 10 seconds. ### Claim 12 (depends on 11) The method of claim 11, wherein rendering an indicator that the live video communication is going to be terminated to the first terminal or the second terminal, before the pre-set time period has elapsed. ### Claim 13 (depends on 11) The method of claim 11, wherein rendering an indicator that the live video communication is going to be terminated to both of the first terminal and the second terminal, before the pre-set time period has elapsed. ### Claim 14 A method for live video communications, comprising: bridging a live video communication between a first terminal and a second terminal by a server device which comprises one or more processors and memory storing instructions to be executed by the one or more processors to bridge live video communications; and terminating the live video communication upon a condition that a pre-set time period has elapsed since the live video communication started, wherein the pre-set time period ranges from 1 to 30 seconds. ### Claim 15 (depends on 14) The method of claim 14, wherein rendering an indicator that the live video communication is going to be terminated to the first terminal or the second terminal, before the pre-set time period has elapsed. ### Claim 16 (depends on 14) The method of claim 14, wherein rendering an indicator that the live video communication is going to be terminated to both of the first terminal and the second terminal, before the pre-set time period has elapsed.
