Method and system for playing multimedia on virtual desktop, cloud-based system for providing virtual desktop and computer readable storage medium applying the method

A cloud-based system for providing virtual desktop comprising:

• a virtual desktop server for building a virtual desktop connection through a network after receiving a virtual desktop request through the network from a client, and for providing a virtual desktop to the client through the virtual desktop connection for the client to display;
• and
• a PUSH server for building a PUSH-mode connection different from the virtual desktop connection with the client through the network, wherein the virtual desktop server drives the push server to build the PUSH-mode connection with the client in response to the virtual desktop server receiving the virtual desktop request from the client;
• and
• wherein the virtual desktop server receives a request of multimedia streaming for obtaining a target multimedia file to display on the virtual desktop of the client through the virtual desktop connection,
• wherein the cloud-based system obtains the target multimedia file and transmits the target multimedia file through the PUSH-mode connection to the client for playing the target multimedia file on the virtual desktop of the client
• wherein the client decodes the target multimedia file to obtain frames of the target multimedia file, and overlaps the decoded frames on the virtual desktop of the client, such that the client plays the virtual desktop after the overlapping.

A non-transitory computer readable storage medium with a computer program to execute a method for playing multimedia on virtual desktop, wherein the method for playing multimedia on virtual desktop comprises:

• (a) receiving a virtual desktop request from a client by a virtual desktop server;
• (b) building a virtual desktop connection by the virtual desktop server to provide a virtual desktop to the client through the virtual desktop connection for the client to display;
• (c) receiving a request of multimedia streaming through the virtual desktop connection by the virtual desktop server for obtaining a target multimedia file to display on the virtual desktop of the client;
• (d) obtaining the target multimedia file from a multimedia server by the virtual desktop server;
• (e) building an additional PUSH-mode connection with the client by a push server and transmitting the target multimedia file to the client through the PUSH-mode connection by the push server for playing the target multimedia file on the virtual desktop of the client, wherein the PUSH-mode connection different from the virtual desktop connection, wherein the virtual desktop server drives the push server to build the PUSH-mode connection with the client in response to the virtual desktop server receiving the virtual desktop request from the client;
• and
• decoding the target multimedia file by the client to obtain frames of the target multimedia file, and overlapping the decoded frames on the virtual desktop of the client, such that the virtual desktop after the overlapping is played by the client.
