Problems solved by technology

Using the vorbis compression algorithm can obtain good sound quality, but the compression time and resource usage may be relatively high, and the compression rate is average, which is suitable for scenes that require high sound quality and low delay requirements; while the compression rate of the speex compression algorithm Very high, short compression time, low resource usage, but poor sound quality, suitable for scenes that have high requirements for delay but not high requirements for sound quality
[0005] In existing remote desktop applications, a compression algorithm is uniformly used for audio compression, so that in some scenarios, users' needs for audio cannot be met

Abstract

The invention discloses an audio transmission method and device to dynamically select an audio compression algorithm. The method provided by the invention comprises the steps that audio trigger information is acquired, wherein the audio trigger information is used to trigger a desktop server to select the compression algorithm used by audio data; the desktop server selects the compression algorithm used by the audio data produced by the audio application according to the audio trigger information; the desktop server uses the corresponding compression algorithm to carry out audio compression on the audio data produced by the audio application according to the selection result of the compression algorithm; and the audio data after audio compression is sent to a desktop client.

Description

technical field [0001] The invention relates to the field of remote desktops, in particular to an audio transmission method and device. Background technique [0002] Remote desktop is a popular technology in the current enterprise office environment. It is often used to transfer the content displayed on a computer screen to another display screen. The commonly used windows remote login program (mstsc.exe) is the most common remote desktop. A desktop program, through which you can easily log in to a remote computer. At present, most remote desktop systems transmit remote desktops based on IP networks. Remote desktop does not only refer to remote screen display, but also includes technologies such as remote sound transmission and pluggable hardware mapping. [0003] Virtual Desktop Infrastructure (VDI, Virtual Desktop Infrastructure) is a way to realize remote desktop; On the display terminal of the desktop, the user's operations on the desktop client are all synchronously ...
