Detailed description of the invention
Fig. 1 show a kind of schematic diagram of set-top box failure restorative procedure based on the embodiment of the present invention.
Specific embodiment
The present invention will be described with reference to embodiments.
Embodiment 1 based on invention, a kind of set-top box failure restorative procedure as shown in Figure 1, comprising the following steps: detection is
It is no to receive booting pass signal, do not activate then Auto-Sensing Mode to proofread startup-program code；Preset check and correction code is read,
Startup-program code is gradually proofreaded based on the check and correction code, corresponding error code is exported according to collation；Based on des encryption mistake
Error code is simultaneously sent to remediation server；Remediation server parsing passes through the error code of encryption and exports corresponding repair data stream,
Set-top box receives the repair data stream and repairs startup-program code based on repair data stream.
Control circuit built in set-top box starts a small routine, the program is for receiving when detecting startup power supply
Be switched on pass signal, and the pass signal that is switched on can be inside boot program, and a signal instruction is issued in final step
Normally start set-top box, is also possible to feed back by the enabling signal of the hardware of set-top box, when these hardware are activated journey
When sequence is driven successfully, the signal of such as electric signal etc is fed back, when detecting these signals, output booting pass signal,
When do not detect be switched on successfully when, activate Auto-Sensing Mode, Auto-Sensing Mode reads preset check and correction code first, pass through detection data
Whether the Information Authentications such as length data are abnormal；Corresponding error code is exported according to Exception Type；Based on 128 des encryption mistakes
Encrypted error code is sent to remediation server by code, and remediation server parses the encrypted error code, reads therein
Information (position including the set-top box that request is repaired, required reparation data etc.), and export corresponding repair data stream, machine top
Box receives repair data stream, according to the content of repair data stream, guides and covers and repair corresponding abnormal data block.
The startup-program code includes several data blocks, and data block includes data head and data subject, the data head
Including data block ID, data length information, crc value and satellite information.
The internal applications (startup program) of set-top box hereinafter referred to as " set-top box App ", using 64K as basic unit, often
64k is a chunk(database block), 128 byte of beginning of each chunk is used to store chunk header information (data
Head)；Then chunk number required for being calculated app.Chunk header information mainly includes chunk id, app
Version, the length of valid data, crc value and reserved information；Set-top box App carries out differentiation storage with such structure, together
Shi Suoyou app chunk header can be stored into inside the chunk of a specific id in the form of data and be preserved.
The naming method of Chunk id is 0xC23Exxxx, and C23E is fixed value, and set-top box App segmentation sequence is since 1
Assignment, such as 0xC23E0001,0xC23E0002 ... ...But 0xC23E0000 is special chunk id, is used to store record just
All App chunk header to begin.
The check and correction code is a data block being stored in startup-program code, and the Auto-Sensing Mode is according to preset
Data block ID reads the check and correction code, based on data block ID gradually read data block locating for non-check and correction code and with proofread generation
Code is compared verifying, is based on verification result output error code.
The particular database of 0xC23E0000 is stored with the check and correction code for verification, and Auto-Sensing Mode extracts this school first
To code, then gradually each others database is verified according to id, then output error code.
Each data head preserves the crc value of oneself data, so we calculate chunk data's (data subject)
CRC and Chunk Header(data head) compared with the crc value that saves.Crc value is different, then the chunk data is destroyed, and needs
It repairs.
The Auto-Sensing Mode further includes the chip identification code for obtaining set-top box, merges chip identification code and error code, is based on
Des encryption is simultaneously sent to remediation server；The repair data stream further includes chip identification code, and set-top box receives the reparation number
According to stream and proofing chip identification code, it is verified and startup-program code is then repaired based on repair data stream.
After completing to test to abnormal data block, STB(digital video switching box, i.e. set-top box are obtained)
Chip id(chip identification code), error code is tied on this chip id, to distinguish the error code of other set-top boxes；Work as reception
To remediation server feed back repair data stream when, equally chip identification code is identified, by then receiving reparation number
According to stream.
The Auto-Sensing Mode further includes that merging chip identification code and error code obtain data combination SUM, to data combination S UM
CRC operation is carried out to obtain its crc value, in conjunction with crc value, data combination SUM and des encryption is carried out, encrypted result is sent to
Remediation server.
In conjunction with chip id and error code to export a data combination S UM, CRC meter is carried out to this data combination SUM
It calculates, obtains crc value；SUM crc value is combined with the data of original chip id and error code to merge, use des encryption algorithm
The combined value is encrypted and result is sent to remediation server.
Based on the embodiment of the present invention 2, Auto-Sensing Mode will be by error code (other parts and above-described embodiment of encryption
1 is consistent), in conjunction with the network address of server, a two dimensional code is generated, then by being displayed on the screen, for customer scans, works as client
The error code two dimensional code for seeing generation scans error code using mobile phone.Error code can be sent automatically to apply to front-end server PC
Software tool can search correspondence according to this error code after PC application tool is connected to error code in the database of the PC software
Correct data, and generate one be directed to this chip id set-top box a reparation code stream.Then it is automatically inserted into front end system
System, user's set-top box can automatic trigger errors repair.
Based on the embodiment of the present invention 3, a kind of set-top box failure repair system, including set-top box and server, wherein institute
Set-top box is stated for detecting whether receiving booting pass signal, does not then activate Auto-Sensing Mode to proofread startup-program code,
Preset check and correction code is read, startup-program code is gradually proofreaded based on the check and correction code, is exported according to collation corresponding
Error code based on des encryption error code and is sent to remediation server；The server is used to parse the error code by encryption
And corresponding repair data stream is exported, set-top box receives the repair data stream and repairs startup program generation based on repair data stream
Code；The set-top box is also used to receive the repair data stream and repairs startup-program code based on repair data stream.
The above, only presently preferred embodiments of the present invention, the invention is not limited to above embodiment, as long as
It reaches technical effect of the invention with identical means, all should belong to protection scope of the present invention.In protection model of the invention
Its technical solution and/or embodiment can have a variety of different modifications and variations in enclosing.
