Method and system for data transmission in cloud terminal system

Abstract

The invention provides a method for data transmission in a cloud terminal system. The method comprises the steps that audio and video transmission parameter values of a corresponding cloud terminal virtual desktop are obtained by a local terminal, wherein the audio and video transmission parameter values are used for representing the audio and video transmission capacity; if the audio and video transmission parameter values are compared with audio and video transmission parameter values of the local terminal and the audio and video transmission capacity of the cloud terminal virtual desktop is stronger than that of the local terminal, audio and video data obtained by the local terminal are offered to the cloud terminal virtual desktop, and the audio and video data are transmitted to an opposite terminal communicated with the local terminal after being coded and decoded by the cloud terminal virtual desktop; otherwise, the obtained audio and video data are transmitted to the opposite terminal communicated with the local terminal after being coded and decoded by the local terminal. According to the method for data transmission in the cloud terminal system, the transmission time is shortened and the transmission efficiency is improved.

Description

technical field [0001] The present application relates to the field of virtualized video compression transmission, in particular to a data transmission method and system in a cloud terminal system. Background technique [0002] In the cloud terminal virtual desktop system, each local terminal corresponds to a unique cloud terminal virtual desktop, and audio and video interactions between two different local terminals are transmitted through their respective cloud terminal virtual desktops. [0003] At present, there are two audio and video interactive transmission methods between two local terminals in the cloud terminal virtual desktop system. The first method: in order to perform audio and video encoding and decoding processing on the local terminal, the processed audio and video The video is transmitted to other local terminals communicating with the local terminal through the virtual desktop of the cloud terminal corresponding to the local terminal. The first method is:...

Problems solved by technology

[0004] However, when only the first method is used for audio and video transmission, if the audio and video transmission capability of the local terminal is worse than that of the corresponding cloud terminal virtual desktop, the local terminal still encodes and decodes the audio and video, resulting in The transfer time to another local terminal is greatly increased

When only the second method is used for audio and video transmission, if the audio and video transmission capability of the cloud terminal virtual desktop is worse than that of the local terminal, the cloud terminal virtual desktop still performs encoding and decoding processing, which will also cause The transfer time to another local terminal is greatly increased

Neither of the two transmission methods weighs the transmission capabilities of the local terminal and the virtual desktop of the cloud terminal. As a result, when the first transmission method is adopted, the transmission capacity of the local terminal is poor and when the second transmission method is adopted, the virtual desktop of the cloud terminal In the case of poor desktop transmission capability, the transmission time is prolonged and the transmission efficiency is reduced

[0005] It can be seen from the above that the current audio and video transmission methods in the cloud terminal virtual desktop system have the disadvantages of prolonging the transmission time and reducing the transmission efficiency
