- the layout information 2000L is defined separately from the layout of the image data
- the information and the layout to be arranged in the auxiliary area 173 can be defined without being influenced by the layout of the image data. That is, the transmission terminal 10 can display the first area ar1 to the sixth area ar6 in the auxiliary area independently of the image data, and the auxiliary area 173 is not affected even if the layout of the image data is changed.
- FIG. 21 is an example of a sequence diagram illustrating a procedure in which the transmission system 1 displays the number of bases when the transmission terminal 10 is in the all-image display mode.
- the procedure in FIG. 21 is executed even if the user does not operate the operation button 108 (FIG. 4) or the like after the session is established in step S47 in FIG. That is, the initial setting for displaying the auxiliary area 173 is set in the transmission terminal 10.
- step S47 may be executed when the user presses the operation button 108 after the session is established in step S47.
- the transmission terminal 10 is the information processing terminal 40
- the procedure of FIG. 21 is executed by pressing a hard key of the information processing terminal 40 or a soft key displayed on the touch panel instead of the operation button 108.
- the transmission terminal 10 designates the URI of the UI providing apparatus 20 acquired in step S25 of FIG. 11, and issues a layout information request signal (an example of an arrangement information request) for requesting layout information 2000L. It transmits to the UI providing apparatus 20.

- the transmission / reception unit 11 of the transmission terminal 10 stores the layout information 2000L in a volatile memory.
- the volatile memory is, for example, the RAM 103. That is, by storing once obtained layout information 2000L in the transmission terminal 10, it is not necessary to acquire the layout information 2000L from the UI providing apparatus 20 again while the power is on. Thus, even when the transmission terminal 10 once erases the auxiliary area 173 and then displays the auxiliary area 173 again, the layout information 2000L can be read from the volatile memory of the transmission terminal 10. Accordingly, since the processing time for acquiring the layout information 2000L can be omitted, the time until the auxiliary area 173 is displayed can be shortened. Further, if the layout information 2000L is stored in the volatile memory, the layout information 2000L can be prevented from leaking from the transmission terminal 10 because the layout information 2000L is erased by turning off the power of the transmission terminal 10.

- the number of existing terminal IDs is calculated. That is, the terminal state acquisition unit 55 identifies the terminal management table 5003T (FIG. 9B) in which the IP address of the transmission terminal 10 that has transmitted the terminal information request signal is registered, and the operation state is “online” from the terminal management table 5003T. All terminal IDs that are “(Transmitting)” are identified and the number is obtained. In the present embodiment, since the terminal ID detected by the terminal state acquisition unit 55 is “01aa”, “01cb”, and “01db”, the number is “3”. The operating state of the transmission terminal 10aa with the terminal ID “01aa” is set to “online (during transmission)” in step S43 of FIG.
- the number of “online (transmission possible)” transmission terminals 10 may be obtained. Thereby, each transmission terminal 10 can display the number of logged-in transmission terminals 10 on the display 120.

- the terminal status acquisition unit 55 may transmit the number of “online (during transmission)” terminal IDs to an online transmission terminal 10 other than the transmission terminal 10 that has transmitted the terminal information request signal. For example, when the number of online terminal IDs is transmitted to the transmission terminal 10aa whose terminal ID is “01aa” in step S86, the number of online terminal IDs is also transmitted to the transmission terminals 10cb and 10db whose terminal IDs are “01cb” and “01db”. Send. As a result, the transmission terminals 10cb and 10db with the terminal IDs “01cb” and “01db” can display the number of bases in the auxiliary area 173 only by receiving the layout information 2000L.
- step S87 the transmission / reception unit 11 of the transmission terminal 10 receives the number of terminal IDs “online (during transmission)”, and the auxiliary area display unit 18 displays the number on the display 120. That is, the auxiliary area display unit 18 interprets the layout information 2000L, determines the position of the auxiliary area 173 and the layout of the first area ar1 to the sixth area ar6, and stores each information in the first area ar1 to the sixth area ar6. The information is set and displayed on the display 120.

- the transmission terminal 10 can display the number of locations participating in the video conference without shifting to the information display mode. Therefore, the user does not need to operate the operation button 108 or the like. Further, since the transmission terminal 10 remains in the all-image display mode, the user can grasp the number of bases while viewing the images of the respective bases. Further, even when the number of bases participating in the video conference exceeds the upper limit of display, the user can accurately grasp the number of bases.
- the user can set the transmission terminal 10 to either “display according to the operation” or “delete after a predetermined time” for the displayed auxiliary area 173.

- a predetermined initial value is set until the user sets the time.
- the user of the transmission terminal 10 can set an arbitrary time in the time setting field 226.
- the upper limit and lower limit of the time that can be set in the time setting field 226 may be defined.
- FIG. 23 is an example of a flowchart illustrating an operation procedure of the transmission management device 50. The process of FIG. 23 is repeatedly executed after the transmission management device 50 calculates the number of terminal IDs that are online in step S85 of FIG. 21, for example.
- step S85-1 the terminal status acquisition unit 55 (FIG. 7) monitors the terminal management table 5003T in which the IP address (or terminal ID) of the transmission terminal 10 that has transmitted the terminal information request signal is registered.
- step S85-2 the terminal state acquisition unit 55 determines whether or not the number of terminal IDs “online (during transmission)” transmitted in step S85 in FIG. 21 has increased or decreased.
- step S85-2 If the determination in step S85-2 is NO, the process in FIG. 23 ends and is repeatedly executed from step S85-1.
- step S85-3 the terminal status acquisition unit 55 determines the current terminal ID whose operation status is “online (during transmission)”. The number is transmitted to the transmission terminal 10. As a result, the transmission terminal 10 that has once acquired the number of terminal IDs that are “online (during transmission)” can always acquire the correct number of bases.
- the terminal state acquisition unit 55 assigns the terminal ID “online (during transmission)” to the transmission terminal 10 “online (during transmission)” other than the transmission terminal 10 that transmitted the terminal information request signal. A number may be sent. Thereby, all the online transmission terminals 10 can always maintain the correct number of bases.
- FIG. 24 is an example of a flowchart showing an operation procedure of the transmission terminal 10. The process in FIG. 24 is repeatedly executed after the transmission terminal 10 displays the auxiliary area 173 in step S87 in FIG.
