Abstract: In a server-client network conference system having a conference server 100 and a plurality of conference terminals 140a to 140n through a network 130, a conference data storage section 120 creates a real-time conference data file 123 and an index file 122 containing time-of-day information and heading information while a conference proceeds. After the conference is over, edit such as voice stream merge processing, image thinning-out processing, etc., in the real-time conference data file 123 is performed to create a minute file 124 and the minute file 124 is managed with an index file 122.

Abstract: It is assumed that a presenter A makes an important statement at a scene 2 in a real-time conference. Participants B and C press a chapter insertion button at times t4 and t5 respectively (steps S1-1 and S1-2). A conference server turns back the time by a predetermined time from the times t4 and t5 (steps S2-1 and S2-2) and sets headings (manual insertion chapters) HCP2 and HCP3 at the turned-back times (t2 and t3). Alternatively, the conference server determines the time separator just before the time (namely, CP4) and sets a heading HCP1 at the time (S4). Accordingly, the heading is set before the scene 2 where the presenter A makes an important statement.

Abstract: In addition to a conference server 100, a record server 200 is provided. The conference data of a real-time conference is stored in a storage section 214 of the record server 200 (S2). A conference terminal 300a performs connection processing to the conference (S1) and then transmits a catch-up playback request to the record server 200 (S3). The record server 200 determines whether or not catch-up playback is enabled (S4) and then distributes the past conference data (S6), and notifies the conference terminal 300a that the catch-up playback end point has come (S7-1). Accordingly, the connection of the conference terminal 300a is switched to the conference server 100 (S9) and the conference terminal 300a is connected to the real-time conference (S10).

Abstract: A network conference system with multipoint connection in which a plurality of users (at least two) are allowed to speak simultaneously, a server-client system in which distribution of information can be easily managed in a centralized manner. A management server (100) executes real-time and dynamic management of the information origination authorization (speech authorization, etc.,) for all sites and on the other hand, an information origination control section (221) of each conference terminal appropriately controls transmission of information from the conference terminal to a network in response to the presence or absence of the information origination authorization.
