Description

Video conferencing multi-point control device capable of connecting to a non-reserved terminal

The present invention relates to a video conferencing system, and more particularly, to a video conferencing system in which a video conferencing terminal is connected to a reserved terminal belonging to a predetermined conference group, And more particularly, to a video conferencing multi-point control device capable of such a video conference.

Recently, as multimedia communication services become popular, multimedia is being developed based on video communication in which a face of a remote party facing away from each other faces and a conversation can be exchanged. Among them, the videoconferencing system is connected to each other through a network that can connect various regions together so that the videoconference system transmits the conference information such as voice and video to the other party. In addition, an Integrated Service Digital Network (ISDN) in which conference information is transmitted at a high speed and at a high speed using a single digital line is disclosed. H.221 is recommended as a method for multiplexing video, audio, and other data to realize video telephony and video conferencing in ISDN. ISDN video telephones and video conferencing devices are referred to as H.320 terminals according to the name of the recommendation. In order to hold a video conference because these video terminals are dispersed in many places, there is a method in which a call is made from a multipoint control unit (MCU) to each terminal and a method in which a call is made from a terminal to a multi-point control unit (MCU) You must select and start the meeting. Particularly, a method of making a telephone call from a terminal requires that a video conference time be reserved in advance in a multi-point control device (MCU) that controls each terminal, and each terminal must call the multi- .

However, since only the registered terminals that are reserved in the conference group are connected to the multi-point control device, unregistered terminals can not be connected. As a result, the composition of the conference group can not be flexibly changed, making it difficult to efficiently operate the conference group. Accordingly, the present invention proposes a video conferencing multi-point control device capable of unassociated terminal access to designate a conference group so that unregistered terminals can participate in a conference group in a fluid manner without reservation.

Accordingly, the video conference multi-point control apparatus capable of connecting to the non-reserved terminal of the present invention is a video conference system including a video conference group name, a memory for storing information of terminals to be present in the conference group, And a variable conference group method in which terminals are variably connected to a conference group, a conference group is designated in the memory, and when a video conference is held, a fixed terminal or a variable And a multipoint control unit (MCU) connected to the terminals for controlling the progress of the video conference.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram illustrating a video conferencing system to which a video conferencing multi-point control device capable of connecting to a non-reserved terminal of the present invention is applied. As shown in the figure, the video conferencing system of the present invention is connected to a plurality of video terminals 14-1, ..., 14-m, ..., 14-n and respective terminals to perform overall control necessary for video conference proceeding The interface unit 11 and the multipoint control unit 12 for performing the interface between the pointing control unit (MCU) 12 and the user and the multi-point control unit 12 store the conference group designation information that can be controlled by the multi- And a memory 13 for storing the data.

1, a user designates a group of conferences through which the multi-point control device 12 can control the progress of the video conference through the interface unit 11. [ In general, the number of conference groups that can be simultaneously controlled by the multi-point control device 12 is two, and the number of terminals that can be connected is limited to sixteen. The multi-point control device 12 stores the reservation contents related to the conference group designation in the memory 13 according to the user's input through the interface 11. [ That is, when a conference group is designated, the conference group is divided into a fixed conference group and a variable conference group. The fixed conference group is divided into a conference group name and information of a fixed terminal belonging to the conference group (for example, Or a telephone number) in the memory 13. On the other hand, for the variable conference group, the conference group name and the fixed terminal belonging to the conference group are registered in the memory 13, and the variable terminal, that is, the other terminal not registered in the conference group, (13). Of course, the variable conference group may specify the conference group name with a specific name, and the terminal for the conference group with this specific name may be automatically set to the unspecified terminal so that the number of terminals in the conference group can be connected. Thus, the multi-point control device 12 connects the terminals attempting connection at the time of holding a conference group of a specific name, on a first-come-first-served basis regardless of whether or not the terminals are registered. A method of using a fixed terminal and a variable terminal together in a conference group is configured by using specific terminal information (for example, special characters) in the case of a variable terminal, and when the terminal is attempting to connect by an unassigned terminal, Group. Thus, the multi-point control device 12 is stored in the memory 13 when the terminals 14-1, ..., 14-m, ..., 14-n attempt to connect in the case of video conferencing belonging to the fixed conference group And accesses the terminal registered in the conference group through the information of the conference group name and the terminal belonging to the conference group. On the other hand, in the case of a video conference belonging to a variable conference group, the multi-point controller 12 checks whether the group is a variable conference group having a specific name stored in the memory 13. If the group is a variable conference group, 14-m, ..., 14-n attempting to connect to the conference group sequentially as many as the number of terminals assigned to the conference group. The multi-point control device 12 accesses within the range of the allocated variable terminals even if the video conference is a variable conference group, if the fixed terminal and the variable terminal are used together.

As described above, the present invention relates to a video conferencing multi-point control device capable of connecting to a non-reserved terminal, in which a conference group is composed of a designated terminal and an unspecified terminal so that members of the group can flexibly change, And the like.

The object of the present invention is to provide a video conferencing multi-point control device (MCU) capable of connecting to a non-reserved terminal, in which not only a terminal reserved in a conference group but also a non- .
