PROBLEM TO BE SOLVED: To allow for video recording of image data, transmitted from a predetermined terminal participating in a remote conference, from the timing when a video recording start instruction is acquired.SOLUTION: A conference server acquires first image data from a first terminal and second image data from a second terminal, and transmits the first image data to the second terminal, and the second image data to the first terminal. The conference server acquires a video recording start instruction, transmits a supplement instruction for instructing creation of supplement data to one specific terminal out of the first and second terminals, thus acquiring supplement data. The supplement data is the data corresponding to a period from a first timing when the video recording start instruction is acquired, to a second timing when an intraframe coding image forming the first image data is acquired for the first time after the first timing. The conference server records the first image data from the second timing, and synthesizes the supplement data and video recording data in time series. |
