Problems solved by technology

[0004] Various protocols currently in use can basically satisfy the transmission of audio redirection in virtualized desktops. However, as people's requirements for audio quality gradually increase, a slight delay and distortion of audio data will cause great inconvenience. For a good user experience, the protocols used by various manufacturers and the processing methods for audio redirection are also different, resulting in different levels of audio experience effects. Especially for thin clients or terminal devices with ARM architecture, the requirements need to be low. Good sound quality experience under system load

Embodiment Construction

[0020] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0021] The key idea of ​​the present invention is to encode the original audio data into the second audio data by hardware through the RDP protocol, so as to reduce the client load while maintaining the sound quality.

[0022] Please refer to figure 1 Embodiment 1 of the present invention provides a method for audio redirection in a virtualized desktop, including:

[0023] S1: Obtain the first audio data through the RDP protocol;

[0024] S2: Transmit the first audio data to the server through the virtual device interface;

[0025] S3: The server encodes the first audio data into second audio data by hardware.

[0026] Specifically, when the player software plays the first audio data, the GUEST system obtains the first audio data through the RDP protocol; the...

Abstract

The invention discloses a method and a system for sound frequency redirection in a virtualization desktop. The method comprises steps of obtaining first audio data through an RDP protocol, transmitting first audio data to a service terminal through a virtual device interface, and coding first audio data hardware code into second audio data by a service terminal. Through above arrangement, the invention can greatly reduce the CPU utilization rate of the client terminal on the premise that the sound quality is guaranteed so as to reduce the whole load of the thin client terminal and break the limitation of the network transmission bandwidth.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a method and system for audio redirection in a virtualized desktop. Background technique [0002] With the continuous development of computer technology, system management becomes more and more complex, and sometimes a single system cannot effectively utilize the resources of the computer platform. Virtualization technology is a decoupling technology that separates the underlying physical device from the upper-level operating system and software to achieve efficient and flexible use of computing resources. The virtualization system can dynamically organize various computing resources and flexibly build computing resources that meet various application requirements. environment, improve the utilization efficiency of computing resources, give full play to the aggregation efficiency of computing resources, and provide users with a personalized and universal computing resour...
