Embodiment Construction
[0123] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0124] The present invention aims at the problem of inefficiency or non-conforming display mode caused by the difference between the sending end and the receiving end in the process of multi-screen interaction in the prior art, and provides a multi-screen interaction method and device, in the same-screen data transmission process , to detect the trigger information of transmission parameter adjustment in real time. When the trigger information satisfies the trigger condition, the sending end and the receiving end negotiate and adjust the first transmission parameter in real time, and then obtain the second transmission parameter suitable for the current same-screen transmission, and then use the second The transmission parameters transmit subsequent same-...

The invention provides a multi-screen interaction method and device. The multi-screen interaction method applied to a sending end comprises the steps that one-screen data is transmitted to a receiving end through a first transmission parameter; in the one-screen data transmission process, trigger information of parameter adjustment is detected in real time; when the detected trigger information meets preset trigger conditions, the first transmission parameter is adjusted, a second transmission parameter is obtained, and subsequent one-screen data is transmitted through the second transmission parameter. In the one-screen data transmission process, the trigger information of transmission parameter adjustment is detected in real time, when the trigger information meets trigger conditions, the sending end and the receiving end negotiate and adjust the first transmission parameter in real time, then the second transmission parameter suitable for current one-screen transmission is obtained, and the second transmission parameter is utilized for transmitting the subsequent one-screen data. According to the multi-screen interaction method, the capacity of the sending end and the capacity of the receiving end are dynamically negotiated, the transmission parameters can be adjusted in time, and the efficiency and effect of one-screen transmission are improved.
Description
technical field [0001] The invention relates to the field of communication technologies, in particular to a multi-screen interaction method and device. Background technique [0002] The multi-screen interactive technology in the prior art mainly includes forced screen switching and resolution negotiation screen switching (a resolution negotiation mechanism is provided before screen switching), but the multi-screen interactive technology in the prior art mainly solves the problem of how to pre-negotiate, Changes in the use process cannot be resolved. [0003] The multi-screen interactive solution includes screen sharing and content sharing. Screen sharing includes processes such as screen capture, encoding, packaging, and sending at the sending end, and receiving, unpacking, decoding, and playing at the receiving end. There is a problem with the same-screen solution, that is, all displays are screen copies. If the scene or reality faced by the receiving end and the sending e...
