Abstract

The embodiment of the invention relates to a transmission method, a device and a system of media streams. The method is executed by an access terminal, and a fist virtual desktop framework VDI channel is established between the access terminal and a network computer distributed to the access terminal by a cloud-end server. The method comprises that a real-time cooperation channel is established between the access terminal and the network computer; the access terminal sends operational orders input by a user via the first VDI channel; the access terminal receives real-time cooperation information sent by the network computer via the real-time cooperation channel; the access terminal carries out media negotiation with a communication device via the network computer to determine media property parameters used for transmitting the media streams between the access terminal and the communication device, wherein information used for the media negotiation is transmitted between the access terminal and the network computer via the real-time cooperation channel; and the access terminal and the communication device mutually transmit the media streams based on the media property diameters determined via the media negotiation.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method, device and system for transmitting media streams. Background technique [0002] Cloud computing is a new way of resource utilization on the Internet, which provides users with on-demand computing based on heterogeneous and autonomous services on the Internet. [0003] The current desktop cloud is also a type of cloud in the definition of cloud computing. The desktop cloud separates the desktop environment of the user terminal (that is, the user application interface) from the physical machine through the cloud computing model, and becomes an externally available user application interface. Services; the computing and storage resources required by the user application interface environment are concentrated on the central server to replace the local computing and storage resources of the terminal; the computing and storage resources of the central server ar...
