Description

Video conference broadcasting system and method

The invention relates to a video conference communication technology, in particular to a video conference data transmission technology related to the field of broadcast transmission.

The video conferencing system is a system that combines network, TV, computer communication and data sharing technology. It can hold meetings between clients located in different locations to transmit sound and images instantly, with real and efficient features. It is a simple and effective technical means of management, command and collaborative decision-making.

Multipoint Control Unti (MCU) is an indispensable device in the video conferencing system. The multipoint control unit is a switching device set on the network node. The video, audio, and control sent by each user terminal. Signals and other data need to complete the same mode conversion through the multi-point control unit, thereby realizing information exchange between user terminals.

In today's video conferencing systems, participants often have to connect to the multipoint control unit through client devices to allow participants to interact with each other, provided that all client devices must be connected to the MCU. However, when conducting a video conference such as product display or education training, the lecturer usually does not interact with all the participants, that is, the participants only need to listen without dialogue with the lecturer, but in order to receive the voice. And the image, each participant will still occupy the MCU resources and the uplink and downlink bandwidth of the network, which will undoubtedly waste the MCU resources and bandwidth.

In addition, the traditional MCU can only support the client to participate in the video conference through the codec (codec), personal computer, and mobile phone, but cannot support the new generation of client devices such as tablet computers and smart phones, resulting in the client device. Restricted in use, and not flexible.

The other embodiments of the present invention will be readily understood by those skilled in the art from this disclosure. Or application.

1 is a schematic structural diagram of a video conference broadcasting system of the present invention. As shown, the video conferencing broadcast system 100 is mainly composed of a conference end 110, a broadcast platform 120, a client 130, and a multipoint control unit 140. In this embodiment, the conference end 110 can be, for example, at least one device such as a video conferencing system, an IP video recorder, or an IPTV. The client 130 can be, for example, a personal computer, a notebook computer, or a smart phone.

The conference end 110, that is, the video conference convening end, is mainly used for transmitting a video conference broadcast invitation to transmit a video conference data stream.

The multipoint control unit 140 has a plurality of data transmission ports, and uses one of the data transmission ports to transmit the video conference broadcast invitation and the video conference data stream transmitted from the conference terminal 110.

The broadcast platform 120 is configured to receive a video conference broadcast invitation and transmit a video conference data stream transmitted from the multipoint control unit 140. The broadcast platform 120 further includes a transceiver module 123, a broadcast module 125, an identification module 127, and a management module 129.

The transceiver module 123 is mainly configured to send the video conference broadcast invitation to each client 130, and receive a video conference link request returned by each client 130 according to the video conference broadcast invitation.

The broadcast module 125 is configured to respond to the video conference link request of each client 130 received by the transceiver module 123, so that the video conference data stream is broadcasted to each of the required clients 130, that is, It is transmitted to the client 130 of each pair of video conferencing link requests.

It should be noted that, in a preferred embodiment of the present invention, the broadcast module 125 may select to transmit the video conference data stream in an immediate or delayed manner. When the broadcast platform 120 transmits the video conference data stream in a delayed manner, the video conference data stream transmitted by the conference terminal 110 may be stored in the storage module of the broadcast platform 120 by using the management module 129 (not shown). In the case, the client 130 for each demand is delayed to download and watch.

The identification unit 127 installs an application 131 in the client 130 to automatically identify the data stream format supported by the client 130 (such as a personal computer, a notebook computer, or a smart phone). The data stream format is supported to transmit the identification result to the identification module 127 of the broadcast platform 120, and the broadcast module 125 broadcasts and transmits the video conference data stream of the corresponding format to each of the corresponding video conference link requests. The client 130 expands the range of use of the client device, improves the performance of the video conferencing broadcast system, and is more flexible.

The management module 129 is for managing, verifying, and recording the video conference data stream.

FIG. 2 is a schematic flow chart of a video conference broadcasting method according to the present invention. As shown in the figure, first, in step S201, the conference end 110 transmits a video conference broadcast invitation, and then proceeds to step S203.

In step S203, the broadcast platform 120 is configured to receive the video conference broadcast invitation via one of the data transmissions of the multipoint control unit 140 to send the video conference broadcast invitation to each client 130, and then proceeds to step S205.

In step S205, the client 130 is configured to receive the video conference broadcast invitation to return to the video conference broadcast invitation according to the actual demand, and return the video conference link request to the broadcast platform 120, and then proceed to step S207.

In step S207, after receiving the video conference link request returned by the client 130, the broadcast platform 120 automatically identifies the data stream format supported by each client 130. In this embodiment, the broadcast platform 120 transmits an identification result supported by the client 130 by using an application 131 in the client 130 to transmit the recognition result. To the broadcast platform 120, step S209 follows.

In step S209, the conference terminal 110 is caused to generate a video conference data stream to transmit the video conference data stream to the broadcast platform 120, and then proceeds to step S211.

In step S211, the broadcast platform 120 is configured to receive the video conference data stream via the data transmission of the multipoint control unit 140 according to the data stream format supported by the client 130, to broadcast the video conference data stream. The forms are transmitted to the respective clients 130 that are responsible for the video conference link request. In the present invention, the broadcast platform 120 can optionally broadcast and transmit the video conference data stream in an instant or delayed manner.

In addition, the broadcast platform 120 can also manage, verify, and record the video conference data stream.

In summary, the video conference broadcasting system and method of the present invention are combined with the broadcast transmission technology. Therefore, it is only necessary to use the broadcast platform to occupy one data transmission port in the multi-point control unit, so that the video conference data stream can be shared with multiple parties. To greatly save hardware resources and network resources.
