Description
Technical field
The present invention relates to a kind of video acceleration method, the video especially related in a kind of virtual desktop display device shows
Accelerated method.
Background technology
Current virtual desktop solution is broadly divided into two big class: VDI (Virtual Desktop
And SBC (Server-Based Computing) Infrastructure).
Virtual desktop solution based on VDI, its principle is to be that each user prepares its special void in server side
Plan machine also disposes the operating system needed for user and various application the most wherein, then by desktop display protocol by complete virtual
Machine desktop consigns to long-range user and uses.Therefore, the basis of this kind of solution is server virtualization.Server virtualization
Mainly having virtualization based on hardware auxiliary and virtualization two kinds based on operating system auxiliary, wherein, the former is a kind of complete
Virtualized method, it is possible to provide one and physical hardware identical virtual hardware ring for the operating system in virtual machine
Border；The latter is then a kind of method of partial virtual, needs to be deployed in void by amendment operating system system
In plan machine.
Virtual desktop solution based on SBC, its principle is to install unified for application software on the remote server, uses
Family by and the session set up of server server desktop and related application conducted interviews and operate, and between different user
Session is isolated from each other.This kind of solution is that (such as keyboard percussion, click, video show at OS Events
Update etc.) insert virtualization layer between layer and application software layer, thus weaken the close-coupled relation between two levels,
The operation making application is no longer limited to ordering about of native operating sys-tern event.In fact, this mode is in previous server version
Windows supports, but in application before, user environment has been fixed on particular server, causes server
Can not be according to loading condition adjustresources dispensing.It addition, application scenarios before is mainly conversational service, its application has
Limitation, does not the most support double-directional speech, supports poor etc. to transmission of video, and the communication between server and user side
There is insecurity.Therefore, novel virtual desktop solution based on SBC mainly provides in server version Windows
Terminal service ability on the basis of the aspects such as the function of virtual desktop, performance, Consumer's Experience are improved.
Regardless of whether be the virtual desktop solution of VDI or SBC, the mainly profit of the multimedia decoding in client device
With Software-only method realize, from server will coding after media stream one by one be transferred to client, soft in client
Directly render after part decoding.Which decoding speed is slow, is that video is the most smooth to user's impression the most intuitively.

Flow data renders, if it has not, then use software mode to render multimedia streaming data.
H.246, JPEG, MPEG4 and RGB the multimedia streaming data coded system kind supporting Hardware Render includes:.
In described step S42, GPU process that multimedia streaming data is rendered is used to specifically include step:
S421: decoded multimedia streaming data is deposited in Installed System Memory；
The decoded multimedia streaming data deposited in S422:DMA controller control system internal memory transmits to GPU；
Multimedia streaming data is rendered by S423:GPU according to decoded multimedia streaming data.
During described step S422, the control of dma controller adapter system bus.
During described step S422, dma controller and CPU alternate access Installed System Memory.
Described Installed System Memory is physical memory and/or virtual memory.
Compared with prior art, the invention have the advantages that
1) mode that the multimedia streaming data supporting hard solution and Hardware Render preferentially uses hardware calculate, can save this
The most rare CPU calculates resource, promotes the response speed of client and plays experience.
2) make full use of software and hardware capability by the hardware multi-media decoding and encoding module in SoC, solve virtual desktop
The problem that the video playback performance of display device is not enough, to realize the function that Video processing is accelerated.
3) multimedia streaming data of various forms is carried out Screening Treatment, reduce the utilization rate of the network bandwidth, hold concurrently simultaneously
Turn round and look at compatibility.
4) data have employed dma mode to the process in GPU from internal memory, and this mode can need not CPU and perform
Transfer, therefore CPU can process the calculating task of oneself, will not be tied down, and improves the efficiency of CPU.
5) using the mode of DMA and CPU alternate access Installed System Memory, CPU neither stops the operation of mastery routine, does not enters
Waiting state, can be more efficient.

Multimedia streaming data is rendered by S423:GPU 2 according to decoded multimedia streaming data.
Using solution based on VDI, user is obtained in that a complete desktop operating system environment, with traditional
The experience of local computer is sufficiently close to.And in this kind of solution, user's virtual desktop can accomplish performance and
The isolation of safety, and have other advantage that server virtualization technology brings, service quality can be protected.But, this
Class solution needs, at server-side portion administration's server virtualization and management software thereof, to want with storage resource calculating resource
Ask higher, there is higher cost.
Using solution based on SBC, application software can install and deploy on server as traditional approach,
Then it is simultaneously supplied to multiple user use, there is relatively low resource requirement, but in terms of performance isolation and security isolation only
It is able to rely on the Windows operating system of bottom.It addition, because what this kind of solution installed on the server is server
Version Windows, desktop version operating system difference that its interface is usual with user, so in order to reduce user in use
Puzzlement, current solution the most only provide the user application software operation interface and and incomplete operating system table
Face.Therefore
The user that virtual desktop based on VDI is relatively more suitable for desktop function demand is perfect uses, based on SBC virtual
The internal user that desktop is more suitable for software requirement is single uses.Therefore the virtual desktop using VDI in the application can be more
Properly.
First the VDI module of server can automatically select current most suitable coded system to coding video data,
And the data stream after coding is sent to client.
