Step 11: The status of the remote desktop window is monitored to determine the active window of the current frame.

In an embodiment of the present invention, the remote desktop, when switching from one window to another window, the window will change state. For example, when a first window, said first window is active, and when the switching from the first window to the second window, said first window is no longer active, then the second the window is active.

FIG 2 is a schematic view of the step of monitoring windows remote desktop video encoding method of the embodiment provided in the embodiment of the invention. In an embodiment of the present invention, the hook may be injected in a global operating system resides in a remote desktop, thus monitored by a window on the desktop state of the global hook.

In the operating system, the hook (Hook) may utilize an application programming interface (API, Application Programming Interface) to intercept messages and the processing system. A hook block is actually processing the message, the system can be linked into the system call. Whenever a particular message is sent, in the absence of the destination window, the program can hook to capture the message, i.e. hooking function may first get control, i.e. time hooking function may analyze the message, processing may continue without the message passing can also force transmitting end of the message. For each type of hook by the system to maintain a chain hook, hook on to start the final installation of the chain, and the first to install a hook on the end of the chain, that is, after adding hooks to gain control.

In an embodiment of the present invention, to achieve injection hook in the system, you can call the API function SetWindowsHookEx Software Development Kit (SDK, Software Development Kit) is to install the hook function prototype for this function is HHOOK SetWindowsHookEx (int idHook, HOOKPROC lpfn, HINSTANCE hMod, DWORD dwThreadId), wherein the first parameter within the parentheses are idHook type hook function; HOOKPROC lpfn second argument is the address of the hook function; HINSTANCE hMod third parameter is the hook function module comprising handle; the fourth parameter DWORD dwThreadId threads specified monitor. If you specify a certain thread, the thread is the special hook; if you specify is empty, is the global hook. Thus, in an embodiment of the present invention, the fourth parameter is specified as null, it can be injected in the system global hook. Global hook function can be included in the dynamic link library (DLL, Dynamic Link Library), the special hook and thread can also be included in the executable file. Gain control of the hook function after the completion of processing of the message, if you want to pass on this message, then it can call another API function CallNextHookEx the SDK to deliver the message. Hooking function may be used to discard the message directly returns TRUE, and prevent transmission of the message.

In an embodiment of the present invention, may be injected in the desktop operating system resides in the global hook, the events within the window intercepted by the global table hook; then analyzing the intercepted event window, thus determining the active window within the desktop of the current frame; obtained after determining the active window of the current frame, the current can be reported to the active window frame encoder for subsequent processing.

In this case, the encoder may determine the identity of the currently active window frame identified in the same reference frame lists certain pre-established. For example, the identification of the current active window frame is A, then the identification of the target can be determined that A. Thus, the target identifier corresponding to the reference frame may be determined as a target with the current active window frame matches the reference frame. That is, the reference frame list may be identified as the reference frame A is determined as the target of the active window of the current frame matches the reference frame. Seen from the above, by matching relationship between the identifier of the reference frame can quickly find the active window and obtain a current frame matches.

In the practical application scenarios, there may be no identification of the currently active window frames of the same target identified in the reference frame of the pre-established list. In this case, not to obtain the reference frame and the frame of the currently active window matches the matching identifier. In an embodiment of the present invention, the reference frames corresponding to one frame may be determined to be the active window of the current frame that matches the target reference frame. That is, assuming the reference mark on a corresponding frame is B, and the identification of the active window to the current frame C, through a query, the reference frame is identified as found C does not exist in the reference frame list, then the when the can corresponding to a reference frame (i.e. B is identified as the reference frame) is determined as the reference frame and the frame of the currently active window matches. Since the contents of the current frame and the previous frame more similar, so use the same reference frame also ensures accuracy of the content.

Step 13: a reference frame of a current frame coded according to the extracted target.

After the embodiment of the present invention, the determination of the target frame and the reference frame with the currently active window matching, encode the current frame based on the extracted target reference frame.

Furthermore, the results also used for encoding the reference frame list is updated. Specifically, in the embodiment of the present invention, the target may be deleted from the reference frame in the reference frame list, the current frame is added to the encoded reference frame list, and after the current frame code assignment reference frame identifier.

Seen from the above, a method of remote desktop video coding according to an embodiment of the present invention, by the desktop window H264 with a preset reference frame corresponding to a reference frame list to thereby be able to select the current window when a handover occurs active window frames a reference frame matches the reference frame list that can be encoded reference frames, when the window switch occurs, since the frame to be encoded and the reference frame is similarity between the current frame can be used with active window It matches a reference frame, thereby reducing the calculation time of the CPU encoder, while reducing network bandwidth utilization.
