Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The double processor communication system adopts two processors, i.e. the first processor and second processor, and wherein first processor is as primary processor, in order to carry out playing programs; The conduct of second processor is from processor, in order to carry out performance recording.
The first processor and second processor communicate through public serial ports, strengthen the data-handling capacity of communication system, the internal memory (DDR) that each processor is corresponding independent, and first processor is connected communication with front panel, remote controller receiving system, and is as shown in Figure 1.
In embodiments of the present invention; First processor is through remote controller receiving system receiving data information; And will send to second processor according to the control command information that this data message produces; Receive control command message pick-up successful information and processing result information that second processor returns simultaneously, and fetch the demonstration that the FLASH control is controlled the programme channel information of said front panel simultaneously.Wherein, said data message comprises Data Update information or key information;
Second processor receives the control command information that said first processor sends; With adding message queue to according to the pairing incident of this control command information; Return control command message pick-up successful information to this first processor, simultaneously the pairing incident of this control command information is handled, and returned the processing result information of incident to this first processor; Wherein, this incident comprises that internal storage data upgrades the associative operation that perhaps user key-press is switched.
In embodiments of the present invention, when this data message was Data Update information, first processor was handed to second processor with the FLASH control simultaneously when this control command information is sent to second processor.
As one embodiment of the present of invention, Fig. 2 shows the realization flow of the double processor communication system communicating method that the embodiment of the invention provides, and the data message that receives with first processor is that Data Update information is that example describes, and its detailed step is described below:
1.1 first processor receives FLASH Data Update information.
1.2 first processor sends to second processor with the control command information of this Data Update information generating, simultaneously the FLASH control is handed to second processor, wherein this control command information is data update event.
1.3 second processor receives the data update event that first processor sends, and adds this incident to message queue simultaneously.
In embodiments of the present invention; When second processor adds this data update event to message queue when unsuccessful; First processor is not if when receiving the reception information of successful of second processor in certain time period; That is: second processor upgrades when overtime internal storage data, just sends data update event to second processor once more automatically, and the said time period is set by the user in advance.
1.4 when second processor successfully adds this data update event to message queue, send the information that successfully receives data update event to first processor.
1.5 second processor upgrades the data in the internal memory.
1.6 after the intact data of second update processor, to the processing result information of first processor transmission incident, promptly internal storage data upgrades the information that finishes.
Finish after the information 1.7 first processor receives the second processor memory Data Update, fetch the FLASH control.
In embodiments of the present invention, when second processor upgrades when overtime internal storage data, first processor is directly fetched the FLASH control.
As an alternative embodiment of the invention; Fig. 3 shows the realization flow of the communication means of the double processor communication system that the embodiment of the invention provides; The data message that receives with first processor is that the button handover information is that example describes, and its detailed step is described below:
2.1 first processor receives the key information that the user remote controller receiving system sends, wherein this first processor is the processor of real-time play program, can't obtain the programme information that this moment, customer requirements was play.
2.2 first processor sends to second processor with this key information control instruction corresponding information, this control command information is the button handover event.
2.3 second processor receives the control command information that first processor sends, and adds the pairing incident of this control command information to message queue simultaneously, wherein the pairing incident of this control command information is the button handover event.
In embodiments of the present invention; When adding this button handover event to message queue, second processor gets nowhere; First processor just sends the button handover event to second processor automatically once more if when in certain time period, not receiving the reception information of successful of second processor.
2.4 when second processor successfully adds this button handover event to message queue, send the information that successfully receives the button handover event to first processor.
2.5 second processor is operated current program according to user's button handover information, for example program is retreated or is advanced etc.
In embodiments of the present invention, after second processor successfully adds the button handover event to message queue, according to the content of this incident, the search program data relevant on hard disk with this content, wait search after, send to first processor.
2.6 after second processor disposes to this button handover event, send the processing result information of incident and upgrade the front panel display message to first processor.
2.7 first processor receives second processor this button handover event is disposed after the information, upgrades the display message of panel, shows the programme information of current broadcast.
In embodiments of the present invention; When user's button handover information is mode switch; If the FLASH control controls at first processor, then obtain the second processor broadcast program information and in front plate show, give second processor FLASH control simultaneously; If the FLASH control is controlled at second processor, the programme information that then first processor upgrades and plate shows current broadcast is in front fetched the FLASH control simultaneously.
In embodiments of the present invention; The processor that replaces single high throughput through the processor of using two lower reason abilities; The processor of said two reduction process abilities carries out interaction data communication; Accomplish each operation of PVR function STB, solved the STB problem of ultra-high price of bringing by the processor that adopts single high throughput, realized the interactive communication of the dual processor in digital TV field simultaneously.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
