Embodiment 1

[0040] In this embodiment, an information queue (which may be referred to as a screen control queue, or a voice activation queue, hereinafter referred to as the queue) is configured on the MCU for storing the site ID, and corresponding to the site ID, it is also stored that the site changes from maximum volume to not The moment of maximum volume (for the convenience of description, hereinafter referred to as the inactive start moment), can further include the maximum sustainable duration of the picture of the venue, and the MCU maintains the queue in real time according to the voice excitation, and controls the video according to the queue Conference screen playback, such as screen switching, screen selection, split screen and other operations.

[0041] Wherein, the maximum sustainable duration of a picture of a venue is a newly added venue parameter in this embodiment on the basis of existing video conference venue parameters. This parameter indicates the maximum time that th...

Embodiment 2

[0075] In this embodiment, a timer can be assigned to each meeting place in the video conference, and the timer duration of each meeting place is the maximum sustainable duration of the picture set for the corresponding meeting place. With the first embodiment, each meeting place can have the same The maximum sustainable duration of the picture can also have different maximum sustainable duration of the picture. Preferably, the maximum sustainable duration of the picture of the chairman site can be set to infinity, that is, it will not time out, or no timer is set for the chairman site in this case. When the timer expires, a timeout signal is sent to the MCU.

[0076] like figure 2 As shown, the process for the MCU in Embodiment 2 to control the playback of the site image may include:

[0077] MCU detects the venue with the loudest volume in each venue of the video conference according to the set cycle, and this process can be the same as embodiment one (step 201);

[0078...

Abstract

The invention discloses a picture control method and a picture control device for a video conference place, which are applied to a video conference system comprising a multipoint control unit (MCU). The method comprises the following steps that: the MCU periodically detects the volumes of the place and adds the picture of a current place with a maximum volume periodically detected by the MCU intoa broadcast picture when the picture of the current periodically-detected place with the maximum volume does not exist in the broadcast picture; and when the picture playing time length of a certain one of the places corresponding to the broadcast picture from the latest moment when the change of the place from a place with the maximum volume to a place without the maximum volume is detected is more than a set time length, the MCU deletes the picture of the corresponding place from the broadcast picture. Due to the adoption of the method and the device, the playing of video conference place pictures can be automatically controlled according to the on-site situation of a video conference.

Description

technical field [0001] The present invention relates to video conferencing technology in the field of communication technology, in particular to a method and device for controlling a picture of a video conference site. Background technique [0002] Video conferencing is a meeting that integrates video, audio, and data communications. It can transmit images and sounds of each venue in real time, so that each venue is logically in a meeting, but physically not in the same area. Compared with traditional conferences, Significant savings can be made without compromising the quality of the meeting. The video conferencing system realizes virtual meetings through network communication technology, gathers geographically dispersed users in one place, exchanges information through various methods such as images and sounds, and carries out collaborative work. Video conferencing shortens the spatial distance to the greatest extent and facilitates real-time and intuitive communication a...
