Accompanying drawing explanation
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the flowchart of a kind of safe and reliable data of set top box programming method of the present invention.
Embodiment
As shown in Figure 1, the data of set top box programming method that the present invention is safe and reliable, comprises the steps:
The data encapsulation that will write pluralizes a deblocking by the maximum data length that step 1, terminal once can be transmitted according to serial ports, and be numbered for each deblocking, also be provided with an identification data in described each deblocking, after identifying this deblocking, whether also have deblocking;
Step 2, plurality of data piecemeal is sent to Set Top Box successively;
Step 3, Set Top Box receive deblocking, carry out data check, and reply terminal one feedback information to this deblocking;
Step 4, according to feedback information, terminal obtains this deblocking accepting state, if this deblocking sends unsuccessfully, then resends this deblocking; Otherwise terminal continues to send deblocking until all deblockings are sent; Terminal calculates time-out time by baud rate, and when terminal confiscates the feedback information of Set Top Box in time-out time, then terminal retransmits this deblocking sent;
After step 5, Set Top Box receive all deblockings, terminal control completes data of set top box programming.
A safe and reliable data of set top box programming system, comprises as lower module:
Package module, the data encapsulation that will write pluralizes a deblocking by the maximum data length that terminal once can be transmitted according to serial ports, and be numbered for each deblocking, also be provided with an identification data in described each deblocking, after identifying this deblocking, whether also have deblocking;
Sending module, sends to Set Top Box successively by plurality of data piecemeal;
Receive feedback module, Set Top Box receives deblocking, carries out data check, and reply terminal one feedback information to this deblocking;
Feedback processing modules, according to feedback information, terminal obtains this deblocking accepting state, if this deblocking sends unsuccessfully, then resends this deblocking; Otherwise terminal continues to send deblocking until all deblockings are sent; Terminal calculates time-out time by baud rate, and when terminal confiscates the feedback information of Set Top Box in time-out time, then terminal retransmits this deblocking sent;
Programming module, after Set Top Box receives all deblockings, terminal control completes data of set top box programming.
A kind of embodiment of the present invention is as follows:
This invention adopts serial ports to carry out the write of segmentation height secure data, and supports retransmission mechanism, data check etc.Because Set Top Box is substantially all with serial ports, so this invention can support the high secure data write of all types Set Top Box, supports the transmission to large data, realize controlling ablation process in real time, ensure correctness and the integrality of high secure data.
Production line terminal encapsulates the data that will write:
If a. data volume is greater than minimum delivery unit (minimum delivery unit is the maximum data length that serial ports once can transmit), carry out block transmission to data, the length of piecemeal is not more than minimum delivery unit; If data volume is less than or equal to minimum delivery unit, then can encapsulate according to following steps.
B. encapsulate piecemeal, wrapper is containing following information:
* total length: the length of packaging information length and piecemeal sum.
* divide block identification: when piecemeal is designated 1, after representing current piecemeal, also have piecemeal; When piecemeal is designated 0, represent that current piecemeal is last in all piecemeals.
* piecemeal sequence number: along with the increase of piecemeal, increase progressively by 1.Piecemeal sequence number and data-bias help set top box side that correct for the data after piecemeal is reassembled as original data.
* data-bias: data-bias is pointed out, longer data after piecemeal, the relative position of current piecemeal in former data.
* block data: the piecemeal being namely not more than the data of minimum delivery unit.
* data check: for the verification that set top box side is correct to the data received, such as CRC check.
2, the piecemeal after encapsulation is sent to set top box side by serial ports.Set top box side keeps the reception buffer memory of serial data by receiving process, make the process of resolution data can obtain the data of needs fast, carry out parsing by parsing process to the block data received to extract, according to check code, data are verified, preserve correct piecemeal, abandon the piecemeal of mistake, and the information of feedback acknowledgment reception or misdata is to production line terminal, then according to piecemeal sequence number and data-bias, block data is assembled into original data.Set-top box software has two process A, B, A process are responsible for ceaselessly receiving serial data and being cached using for B process, B process combines data process analysis.Because B process processing speed is very fast, and Serial Port Transmission speed is relatively slow, does the time that can reduce B process idle waiting data like this, increases concurrent degree, shortens whole programming process.
3, Retransmission timeout and erroneous retransmissions.Production line terminal estimates time-out time by baud rate, when production line terminal does not receive the confirmation that set top box side feeds back corresponding piecemeal in time-out time, will retransmit the piecemeal that this has sent; Or the reception data receiving set top box side feedback when production line terminal are wrong, also can initiate the re-transmission of this piecemeal.
4, based on the feedback information of STB terminal, production line terminal accurately can know the progress that current data writes, and can suspend or the control such as cancellation to the write of data.
Although the foregoing describe the specific embodiment of the present invention; but be familiar with those skilled in the art to be to be understood that; specific embodiment described by us is illustrative; instead of for the restriction to scope of the present invention; those of ordinary skill in the art, in the modification of the equivalence done according to spirit of the present invention and change, should be encompassed in scope that claim of the present invention protects.
