Specific embodiment
The embodiment of the present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this Locate described specific embodiment and is used only for explaining the embodiment of the present invention, rather than the restriction to the embodiment of the present invention.In addition also It should be noted that only parts related to embodiments of the present invention are shown rather than entire infrastructure for ease of description, in attached drawing.
Referring to Fig.1, Fig. 1 is a kind of flow diagram of method for handling message provided in an embodiment of the present invention.
In Fig. 1, the method for the processing message includes:
Step 101, the conversion module in OSD layers receives the instruction message that mobile terminal is sent, and described instruction message includes Remote controller key message, mousebutton message, keyboard message and/or touch screen message;
Wherein, OSD develops engine and selects a kind of to open widely used Tara graphics engine in various embedded devices Hair.Tara graphics engine, developing instrument are also known as Embedded Wizard, are a set of based entirely on object-oriented, provide multiple Animation control can simulate the powerful developing instrument of real effect at the end PC.The engine built-in code compiler (Code Generator) and resource converter (Resource Converter) is according to the difference of target platform, configures different platform packet, The ANSI C/Java code that suitable platform compiling can be generated, is very suitable to code migrating and animation effect is realized.Such as Fig. 2 exhibition Show Tara graphics engine OSD in different platform porting principle figure.
Step 102, the corresponding pulse signal of described instruction message that the conversion module in OSD layers described will receive passes through Analog-to-digital conversion, the digital signal after obtaining conversion;
Step 103, conversion module in OSD layers described by the digital signal by after pre-arranged code algorithm coding, will Digital signal after coding is by being sent to DFB layers after the driving conversion of the port UART;
Wherein, the pre-arranged code algorithm includes STBC coding.Figure accelerated selection one kind is on embedded system platform Widely applied DFB (DirectFB) shape library.DFB shape library is developed small exclusively for embedded device requirement is met Ingeniously, powerful, flexible and wieldy shape library.It provides that figure accelerates, input equipment processing is extracted, transparent window and more The function of weight display layer, can there is preferable support to embedded type GUI.Compared with those other Embedded GUI Systems, it has There are very succinct, efficient architecture and Hardware graphics acceleration function.
Step 104, the conversion module in OSD layers described is converted the digital signal after the coding by described DFB layers For described instruction message, and described instruction message is sent to OSD and is handled.
Specifically, remote controller key passes through keying panel infrared receiving device in infrared emission, television set, the arteries and veins that will be received Signal is rushed by analog-to-digital conversion, is encoded by STBC, is converted by the port the uart driving of mainboard chip, then give DFB layers, After DFB receives corresponding key, corresponding press key message is sent, Tara Task is responsible for receiving and conversion DFB comes into the Key come and disappears Message is finally transmitted to Tara UI (OSD) correlation Task processing by breath.Fig. 3 receives the process handled from UI is emitted to for MENU key Figure.
In addition, it is almost the same with keystroke handling for mouse, keyboard and touch screen Message Processing, it is set the difference is that receiving Standby and DFB conversion.Such as mouse device, mouse-driven receives message, is converted into mouse down by DFB and mouse movement disappears Breath is then forwarded to UI processing.
The embodiment of the present invention provides a kind of method for handling message, by increasing OSD between extraneous mobile terminal and OSD Layer in conversion module, it is OSD layer described in conversion module receive mobile terminal transmission instruction message, described instruction message package Include remote controller key message, mousebutton message, keyboard message and/or touch screen message;Conversion module in OSD layers described Digital signal by the corresponding pulse signal of described instruction message received by analog-to-digital conversion, after obtaining conversion;The OSD Conversion module in layer is by the digital signal by the way that after pre-arranged code algorithm coding, the digital signal after coding is passed through UART DFB layers are sent to after the driving conversion of port;Conversion module in OSD layers described passes through described DFB layers for the number after the coding Word signal is converted to described instruction message, and described instruction message is sent to OSD and is handled, and develops phase with traditional OSD Than the program has abandoned different OSD developing instruments, is used uniformly the exploitation of Tara graphics engine;It can be not by a set of OSD Same chip solution transplanting, reduces the work of overlapping development;Set OSD realizes that framework is well arranged, key/event handling stream Cheng Minglang, interface are realized independently, to substantially increase development efficiency.
It is a kind of flow diagram of method for handling message provided in an embodiment of the present invention referring to Fig. 4, Fig. 4.
On the basis of Fig. 1, the method for the processing message further include:
Step 401, (APP layers) initialization creation event message processing threads of application layer and event message queue;
Step 402, (Driver layers) of the layer monitoring event message queues are driven;
Step 403, if having monitored message arrival, what the application layer converted the message to that TARA defines disappears Breath, and update the state of the OSD.
Specifically, bottom (for example, layer Driver layers of driving) needs to send dependent event, OSD wants synchronized update.Such as sweep platform In the process, Tuner can send lock/unlock event according to current frequency, and OSD needs to show current frequency point, searches out program Several and entire progress.Tara OSD realizes message from different scheme platforms as how an independent drawing engine modules are realized Transmitting, Fig. 5 are the flow chart for showing event message pass through mechanism.
It is a kind of flow diagram of method for handling message provided in an embodiment of the present invention referring to Fig. 6, Fig. 6.
