Abstract
Abstract A multi-location conference system has conference terminals (3) connected to a conference device (1), which stores information for the conferences. A reservation center (5) registers and deletes conference information in and from the conference device (1) at times designated in accordance with reserved conference information collected in advance for the respective conferences, thereby controlling automatically the starting and ending of each of the conferences. <IMAGE>

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
141 words
A multi-location conference system comprising: a plurality of conference terminals (3) performing input and output of conference data consisting of video and audio signals; and a conference device (1) which is connected to said plurality of conference terminals (3) and which holds conferences between said plurality of conference terminals (3) by synthetic processing of conference data sent to it; characterized in that said conference device is provided with a conference table (17) storing information for the conference terminals participating in the conferences being held; and said system further comprises a reservation center (5) for registering conference terminal information in said conference table (17) and deleting the conference terminal information from the conference table (17) at times designated in accordance with reserved conference information collected in advance for the respective conferences, thereby controlling automatically starting and ending of each of the conferences.
Claim 2
Dependent Claim
21 words
The system of claim 1, characterized in that said conference device (1) is capable of holding a plurality of conferences simultaneously.
Claim 3
Independent Claim
170 words
The system of one of claims 1 or 2, characterized by further comprising at least one reservation terminal (8) connected with said reservation center (5) via a communication line (6, 7); wherein said reserved conference information comprises a reservation decision information requisite for making the decision as to whether to accept or reject the reservation, and reservation detail information required for control over performing the conference; said reservation terminal (8) sends the reservation decision information via said communication line (6, 7) to said reservation center (5); said reservation center (5) makes, responsive to the reservation decision information, a decision as to whether to accept or reject the reservation at said reservation center (5), and sends the result of decision from said reservation center (5) to said reservation terminal (8); and said reservation terminal (8) sends, if the result of the decision is to accept the reservation, the reservation detail information to said reservation center (5), thereby to achieve the registration of said reserved conference information to the reservation center (5).
Claim 4
Dependent Claim
191 words
A multi-location television conference system characterized by a plurality of first television conference terminals (106) that can be connected to a communication network (104) with a first line speed; a plurality of second television conference terminals (107) that can be connected to said communications network (104) with a second line speed; a plurality of conference devices (105) which are connected by a plurality of lines to said communication network (104), and which are capable of simultaneously holding multi-location conferences at a selected one of said first and second line speeds; and an operational management device (108) to which said conference devices (105) are connected, which determines, at the time of convening a multi-location conference (105), the conference device which is to hold the conference by searching for the conference device (105) which can hold the conference with the line speed with which the television conference terminals (106, 107) participating in the conference can be connected, and the line speed and the number of vacant lines of each of the conference devices (105), in an order different depending on the specific line speed, and which controls starting and ending of the conference.
Claim 5
Dependent Claim
31 words
The system of claim 4, characterized in that said order predetermined for said first line speed and said order for said second line speed are sequential orders reverse to each other.
Claim 6
Independent Claim
29 words
The system of one of claims 4 or 5, wherein said first conference terminals (106) can also be connected to a communication network (104) with said second line speed.
Claim 7
Dependent Claim
278 words
A multi-location television conference system, characterized by a plurality of first television conference terminals (106) that can be connected to a communication network (104) with a first line speed; a plurality of second television conference terminals (107) that can be connected to said communications network (104) at a second line speed; a plurality of conference devices (105) which are connected by a plurality of lines to said communication network (104), and which are capable of simultaneously holding multi-location conferences with a selected one of said first and second line speeds; and an operational management device (108) to which said conference devices (105) are connected, which has a reservation file (146) capable of storing reserved conference information including starting time and ending time of each of the multi-location conferences and a clock (147) by which it is possible to indicate the current time, which reserves a conference device (105), and which controls starting and ending the conference; wherein, at the time of reserving a multi-location conference, said operational management device (108) determines, in accordance the number of the conference terminals (106, 107) which are to participate in the conference, as well as the line speed with which the reservation has been made for each conference device (105), and the number of vacant lines of each conference device (105), the conference device (105) which is to be reserved for the conference by searching for the conference device (105) which can hold the conference with the line speed with which the television conference terminals (106, 107) which are to participate in the conference can be connected, wherein said search is made in an order different dependent on the specific line speed.
Claim 8
Dependent Claim
31 words
The system of claim 7, characterized in that said order predetermined for said first line speed and said order for said second line speed are sequential orders reverse to each other.
Claim 9
Independent Claim
29 words
The system of one of claims 7 or 8, wherein said first conference terminals (106) can also be connected to a communication network (104) with said second line speed.
