Provided are a screen brightness adjustment method, multipoint controller unit (MCU) and terminal, the method comprising: an MCU determines to adjust the brightness of one or more sub-screens in a plurality of screens; and the MCU adjusts the brightness of one or more sub-screens in the plurality of screens according to a predetermined brightness adjustment method, the predetermined brightness adjustment method comprising at least one of the following: determining a brightness adjustment value by the MCU, and determining the brightness adjustment value by a remote terminal receiving the plurality of screens. The present invention solves the problem in the relevant art that a large brightness deviation in the screens of a multi-screen conference system affects screen perception, thus adjusting the brightness of one sub-screen in the plurality of screens improves the watching experience of all the screens.
Description
technical field [0001] The present invention relates to the communication field, in particular, to a screen brightness adjustment method, a multi-point control unit MCU and a terminal. Background technique [0002] A basic multi-screen video conference system generally consists of at least two terminal devices, a transmission network, and a multipoint control unit (Multipoint Controller Unit, MCU for short). MCU is the core of the video conference system. In a multi-screen conference, the MCU is responsible for decoding the video sent by each terminal, and then synthesizes it into a multi-screen, and then encodes it to each terminal according to the requirements of the conference. [0003] In the context of converged communication, the MCU will be connected to various devices with video communication capabilities other than traditional conference TV terminals, such as various monitoring equipment, recording and broadcasting equipment, smart phones, desktop terminals, etc. A...
