Embodiment 1

[0067] The telepresence conference system in this embodiment is as follows image 3 As shown, it includes three conference terminals (conference terminals 3011, 3012, 3013), an audio-visual exchange unit 302, three sets of audio-visual terminal equipment (audio-video terminal equipment 3031, 3032, 3033) and a control unit 304, wherein:

[0068] AV end devices 3031, 3032, 3033 are used to collect local audio and / or video signals, output the locally collected audio and / or video signals to the AV switching unit 302, and play the received audio and / or video signals from the AV switching unit 302 received audio and / or video signals;

[0069] The conference terminals 3011, 3012, 3013 are used to decode the external audio and / or video data obtained from the external network and output them to the audio-visual exchange unit 302, and output the audio and / or video signals obtained from the audio-visual exchange unit 302 after encoding to external networks;

[0070] A video and audio e...

Embodiment 2

[0081] The telepresence conference system in this embodiment is as follows Figure 4 As shown, compared with the telepresence conference system in Embodiment 1, the telepresence conference system in this embodiment includes four conference terminals (conference terminals 3011, 3012, 3013, 3014), wherein conference terminal 3014 is a backup conference terminal . In this embodiment, when the control unit 304 determines that a conference terminal in use is faulty, it will activate the backup conference terminal 3014, and instruct the audio-visual exchange unit 302 to switch the audio and / or video signals of the conference terminal in use to the backup conference terminal. The conference terminal 3014 constitutes a reliable k / n voting subsystem (k=3, n=4). In actual implementation, the k value is not necessarily the same as the number of sets of audio-visual terminal equipment. For example, there are three sets of audio-visual terminal equipment in the system In the case of equip...

Embodiment 3

[0093] In this embodiment, certain improvements are made to the line subsystem. In the existing telepresence conference system, each conference terminal is connected to an external network respectively, and a failure of any line will cause a system failure, and the reliability is low. If each line is backed up directly, there will be a lot of backup lines. Therefore, in this embodiment, a network switching unit is added between the conference terminal and the external network, and is connected to the external network through at least two lines for data transmission between the external network and the conference terminal. The two lines are The parallel relationship constitutes a reliable parallel subsystem, that is, when one of the lines fails, the other line can still guarantee the data transmission between the external network and the network switching unit. For the case of Ethernet access, the network switching unit can be realized by using an Ethernet switch device.

Abstract

The invention discloses a remote-presence conference control device, a method and a remote-presence conference system; the system comprises video end equipment, a video interchange unit, a plurality of conference terminals, and at least one control unit; wherein the video interchange unit is used for leading an audio and / or video signal collected locally to be output to the conference terminal, and receiving a signal output by the conference terminal to transmit to the video end equipment, and the switching-over of the audio and / or video signal is carried out according to the indication of thecontrol unit; the control unit is used for indicating the video interchange unit to switch over the signal on the conference terminal with fault to the conference terminal without fault. As the videointerchange unit is additionally arranged, when determining a certain conference terminal to have faults, the control unit can indicate the video interchange unit to switch over the signal on the conference terminal with fault to the conference terminal without fault, thereby improving the reliability of the remote-presence conference system.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a control device and method for a telepresence conference and a telepresence conference system. Background technique [0002] Existing multi-screen telepresence conferencing systems use multiple video conferencing terminals bundled with multiple peripherals (such as multiple TV sets and multiple cameras) to form a venue, so that the images captured by each camera are passed through the corresponding terminal. After encoding, it is sent to the remote end, and the terminal receives the remote code stream and decodes it to output through the corresponding display, which can achieve close to life size and solve the problem of eye-to-eye communication to a certain extent. [0003] Taking the telepresence conference system in the prior art including three conference terminals as an example, the connection relationship is as follows: figure 1 As shown, it includes three conference terminals...
