Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and method for providing a conference call service using broadcast,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fusion technology of broadcasting and communication, and more particularly, to a broadcasting technology in which a broadcasting file including a moving picture photographed for a broadcasting conference is received from various participants attending a broadcast- And more particularly, to a system and method for providing a conference call service using a broadcast, which implements a conference call using a broadcast when a broadcast file is shared and broadcasted in a time zone designated by the broadcast conference.

A video conferencing solution is a system that allows a conference to be held remotely and using video conferencing equipment. The video conference system transmits video, audio, and various document data in real time and displays voice, image, and document using various devices such as monitor and projector, so that remote conference can be performed at any time without restriction of space and time.

A basic element that enables such video conferencing is a video conferencing system and a communications line that carry video and audio from meeting participants.

Videoconferencing systems are various devices based on various video communication protocols (H.323, SIP, H.324M). ATMs and ISDN have been used for communication lines. Recently, according to the development of IP, ADSL, And the like are generally used.

The Multipoint Control Unit (MCU) provides the ability for three or more terminals and gateways to participate in multipoint conferences for video conferencing.

With the development of multiplexing technology in digital broadcasting, it has become possible to bundle video, audio, and data at the same time regardless of their contents and size, and a return channel through a modem has been formed to enable bidirectional broadcasting technology. Enables various receiving functions to be performed.

The two-way broadcasting technology is that the information flow between viewers and broadcasters is unidirectional rather than unilaterally like current analog TV. That is, the viewer is provided with various interactive additional information from the broadcasting company, and accesses additional information provided by the viewer through a separate dedicated line to the linked site and receives the desired information.

In a traditional video conferencing system, the MCU is required to connect a 1: 1 bidirectional line with all attendees to send the results of the video conferencing participants to the videoconferencing participants, as the number of attendees increases. The network resources of the network are wasted.

Also, there is a problem that the participants of the recall meeting waste the network resources by maintaining the sentence with the MCU and transmitting the media generated by the encoder even though they do not want to send information.

A solution is needed.
