摘要： PURPOSE:To provide the communication conference system keeping a voice signal of a talker to be a level easily listened to independently of number of conference participants so as to contribute to the smooth progress of the conference. CONSTITUTION:A voice addition/distribution section 232 uses an attenuation level adjustment section 20 to variably adjust a level adjustment attenuation for attenuators 31-34 corresponding to conference terminals 101-104 when voice signals from the conference terminals 101-104 are added by an adder 50. As a parameter for the adjustment of the attenuation, the result of discrimination of sound/non-sound of the voice signal from each conference participant, for example, is used, and concretely when talkers of the conference terminals 101, 102 make utterance simultaneously and the sound state is discriminated, the attenuation of the voice signal of the talker is adjusted smaller than the attenuation of the voice signals from the conference terminals 103, 104 not making utterance.

摘要： PURPOSE:To generate a united sense between a terminal in use and its opposite terminal by executing the image pickup control of the terminal in use also together with that of the opposite terminal when the image pickup control of the opposite terminal is instructed and changing the sound output level of the opposite terminal while interlocking with the image pickup control. CONSTITUTION:It is supposed that a user of a 1st communication equipment 1 instructs zoom-up operation from an operation part 116 to an image pickup part 23 in a 2nd communication equipment 2. The operation part 116 transmits the instruction to a communication control part 111 and instructs the zoom-up operation to an image pickup control part 17. An image pickup part 13 executes the zoom-up operation based upon the instruction. The operation part 116 informs a sound control part 118 of the increment of a sound output from the 2nd equipment 2 and a sound output part 14 increases an output level. The control part 111 informs the equipment 2 of the instruction from the operation part 116. In the equipment 2, an image pickup control part 27 executes the zoom-up operation of the image pickup part 23. A sound control part 228 increases the output level of a sound output part 24.

摘要： PURPOSE:To enlarge communication location and to emphatically display the image of a speaker by varying an extracting area on a screen corresponding to the number of attendants at the time of synthesizing video signals from respective TV conference terminals, and modifying the arrangement at the time of synthesizing the extracting areas. CONSTITUTION:Video signals from respective TV conference terminals 1a-1f are signal-converted in interface parts 3a-3f, decoded by video line processing parts 4a-4f, and thus video synchronization is attained. Then, based on conference control signals (number of communication locations, number of conference attendants, segmented size/position information) from a specified terminal (for instance a terminal 1a at which a conference master of the chairman participates), a reduced picture is generated. A video multiplex switching part 12 generates the picture of a specified location or a reducing synthesis picture from each terminal corresponding to a request from each terminal, and the data is coded again in a processing part 4, then multiplexed with a voice signal from a voice line processing part 7, and further signal-converted in the interface part 3, thereafter, the data is distributed to respective terminals through a line 10.
