A kind of cloud displayer supporting the full frame display of the dynamic convergent-divergent of pictureTechnical field
The present invention relates to field of display, particularly a kind of cloud displayer supporting the full frame display of the dynamic convergent-divergent of picture.
Background technology
Remote desktop host-host protocol (Remote Desktop Protocol, RDP) RDP is a set of standard agreement for carrying out remote desktop access on network that Microsoft formulates, and it belongs to the application layer of network protocol suite.The Main Function of RDP allows user can be connected to a remote Windows server (this startup of server the service of Terminal Service) by RDP cloud displayer exactly.Set up with remote server the cloud displayer be connected by RDP, the desktop of complete remote server can be obtained, and on this desktop operations server, whole operating process is the same with the effect directly operated on the remote server, is very easy to server maintenance personnel.
The cloud displayer of conventional cloud server uses Box Client plate+Scalar IC mainboard, when performing RDP and transmitting picture, Client Monitor(cloud displayer) resolution of fixing can only be accepted and cause cloud displayer to show discontented frame, picture frame has black surround, or causes cloud displayer OSD (On-Screen Display) menu to be become different proportion by proportional zoom and be out of shape because output resolution ratio is different.
Summary of the invention
Object of the present invention keeps the full frame of picture to export and the indeformable a kind of cloud displayer supporting the full frame display of the dynamic convergent-divergent of picture of OSD menu image for providing a kind of.
To achieve these goals, the present invention is by the following technical solutions:
The cloud displayer of the full frame display of the dynamic convergent-divergent of this support picture, it comprises cloud displayer, embedded network communication microcontroller, storer and IC internal memory, and described embedded network communication microcontroller is connected with the RemoteFx 3D video image engine of cloud displayer, storer, IC internal memory and cloud server respectively; Described cloud displayer is provided with interface, is connected with the dummy machine system of Cloud Server by interface.
The concrete steps of the cloud displayer of the full frame display of the described dynamic convergent-divergent of support picture comprise:
1) data bitmap that the dummy machine system that the embedded network communication microcontroller described in decodes Cloud Server by RDP sends, and decoded bitmap is stored in IC internal memory;
2) the RemoteFx 3D video image engine described in, according to different input resolution, exports full frame picture to the full frame of the according to pixels unit calculating of the bitmap in IC internal memory interpolation proportional zoom;
3) OSD menu image exports OSD picture by RemoteFx 3D video image engine in 1:1 ratio;
4) by step 2) in full frame picture and OSD picture in step 3) be stored in two different storeies respectively;
5) RemoteFx 3D video image engine merges full frame picture in two different storeies and OSD picture exports cloud displayer to.
Further, described interface is RJ45.
Further, described storer is DDR (Double Data Rate).
Further, NADN-flash is saved as in described IC.
The present invention adopts above technical scheme: be connected with the dummy machine system of Cloud Server by the interface of cloud displayer; The data bitmap that the dummy machine system that described embedded network communication microcontroller decodes Cloud Server by RDP sends, and decoded bitmap is stored in IC internal memory; Described RemoteFx 3D video image engine, according to different input resolution, exports full frame picture to the full frame of the according to pixels unit calculating of the bitmap in IC internal memory interpolation proportional zoom; The picture of cloud displayer can be made not by the impact of the change of resolution, and full frame exports.OSD menu image exports OSD picture by RemoteFx 3D video image engine in 1:1 ratio; The OSD menu image that cloud displayer is exported keeps original size, indeformable.Full frame picture and OSD picture are stored in two different storeies respectively; Full frame picture and OSD picture is made to realize controlling separately.

Embodiment
According to Fig. 1, the present invention includes cloud displayer, embedded network communication microcontroller, storer and IC internal memory, described embedded network communication microcontroller is connected with the RemoteFx 3D video image engine of cloud displayer, storer, IC internal memory and cloud server respectively; Described cloud displayer is provided with RJ45 interface, is connected with the dummy machine system of Cloud Server by RJ45 interface;
The concrete steps of the cloud displayer of the full frame display of the described dynamic convergent-divergent of support picture comprise:
1) data bitmap that the dummy machine system that the embedded network communication microcontroller described in decodes Cloud Server by RDP sends, and decoded bitmap is stored in IC internal memory NAND-flash;
2) the RemoteFx 3D video image engine described in, according to different input resolution, exports full frame picture to the full frame of the according to pixels unit calculating of the bitmap in IC internal memory interpolation proportional zoom;
3) OSD menu image exports OSD picture by RemoteFx 3D video image engine in 1:1 ratio;
4) by step 2) in full frame picture and OSD picture in step 3) be stored in two different storer DDR respectively;
5) RemoteFx 3D video image engine merges full frame picture in two different storer DDR and OSD picture exports display to.
The present invention can make the picture of cloud displayer not by the impact of the change of resolution, and full frame exports.OSD menu image exports OSD picture by RemoteFx 3D video image engine in 1:1 ratio; The OSD menu image that cloud displayer is exported keeps original size, indeformable.Full frame picture and OSD picture are stored in two different storeies respectively; Full frame picture and OSD picture is made to realize controlling separately.
