Abstract
A multi-image adjusting method and device and a Multipoint Controller Unit (MCU) are provided. The method includes that: the MCU receives code streams sent by multiple terminals, and synthesizes a multi-image after decoding videos; the MCU receives an adjustment request for a sub-image in the multi-image, and adjusts a display parameter of a corresponding sub-image according to the adjustment request; and the MCU codes and sends the adjusted multi-image to a corresponding terminal.
Claims18
A multi-image adjusting method, comprising:
- receiving, by a Multipoint Controller Unit, MCU, code streams sent by a plurality of terminals, and synthesizing a multi-image after performing decoding to obtain video data;
- receiving, by the MCU, an adjustment request for a sub-image in the multi-image, and adjusting a display parameter of a corresponding sub-image according to the adjustment request;
- and
- coding and sending, by the MCU, the adjusted multi-image to a corresponding terminal.
A multi-image adjustment device, arranged in a Multipoint Controller Unit (MCU) and comprising:
- a processing module, configured to receive code streams sent by a plurality of terminals, and synthesize a multi-image after performing decoding to obtain video data;
- an adjusting module, configured to receive an adjustment request for a sub-image in the multi-image, and adjust a display parameter of a corresponding sub-image according to the adjustment request;
- and
- a sending module, configured to code and send the adjusted multi-image to a corresponding terminal.
A Multipoint Controller Unit, MCU, comprising:
- a network interface, configured to receive code streams sent by a plurality of terminals;
- a decoder, configured to decode the code streams to obtain video data;
- a synthesis module, configured to synthesize the video data into a multi-image;
- and
- a coder, configured to code the synthesized multi-image to send through the network interface,
- wherein
- the network interface is further configured to receive an adjustment request for a sub-image in the multi-image;
- the synthesis module is further configured to adjust a display parameter of a corresponding sub-image according to the adjustment request;
- and
- the coder is further configured to code the adjusted multi-image to send to a corresponding terminal through the network interface.
