It should be noted that, the identity information of Set Top Box can be hardware version ID and the user ID value of Set Top Box type, can be also the distinctive data messages relevant with type such as the machine model of this type, regional value.Within every information relevant with the Set Top Box type can be incorporated in the scope that identity information checks.
Step 200, the identity information of Set Top Box self is encrypted, and generates identifying information.
In the present embodiment, for the identity information of Set Top Box self, adopt the MD5 algorithm to be encrypted, generated identifying information.The MD5 algorithm is a kind of md5-challenge, is to allow large capacity information be become a kind of secret form (being exactly the byte serial of a random length to be transformed into to the large integer of a fixed length) by " compression " before with digital signature software, signing private secret key.By by the MD5 algorithm for encryption, making user profile well be protected.
And the standard information in the upgrading trigger message is also by MD5 algorithm for encryption gained, its advantage by the MD5 algorithm for encryption is, the byte serial of identity information can be transformed into the large integer of one fixed length, therefore when the identifying information of Set Top Box is compared with upgrading trigger message Plays information, only need relatively their MD5 value, can judge that whether these two kinds of information are identical.
Step 201, Set Top Box receives the upgrading trigger message.
In an embodiment, the upgrading trigger message can be sent to Set Top Box by transport stream TS stream, and TS stream, when carrying the upgrading trigger message, also carries upgrade data information.In specific implementation, upgrade data information can be realized by function (Software_update_section ()).Trigger message and the upgrade data information of wherein upgrading is included in a group name in the table of (table_id), when the value of the table_id positional value that is 0x8D interval scale upgrading trigger message place; When the positional value that the value of table_id is 0x90 interval scale upgrade data information place, when Set Top Box need to be upgraded, the upgrading trigger message finds the positional value at upgrade data information place in table_id, and extracts upgrade data information and download.
Step 202, whether judgement upgrading trigger message and upgrade data information have renewal.
In specific implementation, whether judgement upgrading trigger message and upgrade data information have renewal to judge according to the variation of version number in (Software_update_section) function, when upgrade trigger message and upgrade data information have renewal, in corresponding (Software_update_section) function, the field of version number (version_number) can add " 1 " on original value.Therefore can judge according to the variation of version number value whether upgrading trigger message and upgrade data information have renewal.Perform step 203 when having judged while upgrading, when judging while not upgrading, perform step 210, cancel upgrading.
Step 203, during being judged as upgrading trigger message and upgrade data information renewal is arranged of the step 202 that continues, further judge whether the identifying information of Set Top Box self is complementary with one of them standard information of upgrading trigger message.
In the present embodiment, in (Software_update_section) function, the value of version number can change to some extent owing to upgrading, the concrete value of version number is shone upon the standard information of n Set Top Box type in (Software_update_section) function, and these standard information are all through the MD5 algorithm for encryption.Therefore, when whether the identifying information that judges Set Top Box self is complementary with one of them standard information of upgrading trigger message, by the MD5 value of the standard information of n Set Top Box type in the MD5 value of the identifying information of Set Top Box self and (Software_update_section) function, compare one by one, the MD5 value that the standard information of a Set Top Box type is arranged in comparing out function is that the MD5 value with the identifying information of Set Top Box self is when identical, the identifying information that Set Top Box self is described has the standard information be complementary with it, can continue to carry out the judgement that next step is step 204.
Be MD5 value with the identifying information of Set Top Box self when identical without any the MD5 value of the standard information of a Set Top Box type in inquiring function, directly perform step 210, cancel upgrading.
Step 204, the result of the step 203 that continues judgement is the identifying information that inquires Set Top Box the self when standard information be complementary with it is arranged, and continues judge that the software version of identifying information of Set Top Box self is whether lower than the software version of the standard information of mating.
If the software version of the identifying information of Set Top Box self, lower than the software version of the standard information of coupling, performs step 205; If the software version of the identifying information of Set Top Box self, higher than the software version of the standard information of coupling, directly performs step 210, cancel upgrading.
Step 205, the software version of the identifying information that the result of the step 204 that continues judgement is Set Top Box self is lower than the software version of the standard information of coupling, judges that the sequence number of identifying information of Set Top Box self is whether in the sequence number extent of competence that the standard information of coupling limits.
As a kind of enforceable mode, in the present embodiment, each Set Top Box has unique sequence number corresponding with it when dispatching from the factory.In the upgrading trigger message, each standard information correspondence the sequence number extent of competence, as long as the sequence number of Set Top Box self can meet promotion condition in this scope.In (Software_update_section) function, the minmal sequence of set top box upgrading number means with (STB_id_begin) statement, and maximum sequence number is meaned by (STB_id_end) statement.
If the sequence number of the identifying information of judgement Set Top Box self, in the sequence number extent of competence of the standard information restriction of coupling, meets above promotion condition, perform step 206.If, in the sequence number extent of competence that the sequence number of the identifying information of Set Top Box self does not limit in the standard information of mating, directly perform step 210, cancel upgrading.
Step 206, whether judgement upgrading type is common upgrading type.
In specific implementation, in the time of in the sequence number extent of competence that the sequence number of the identifying information that the result of the step 205 that continues judgement is Set Top Box self limits in the standard information of mating, the standard information of coupling has defined the upgrading type of this Set Top Box.It means with (upgrade_kind) in (Software_update_section) function.Performing step at 206 o'clock, whether the upgrading type of defined this Set Top Box of standard information of judgement coupling is common upgrading type.If common upgrading type, perform step 207; If judged result is not common upgrading type, perform step 208, the upgrading type of defined this Set Top Box of standard information of coupling is the mandatory upgrade type.
Step 207, whether the user needs upgrading.
In step 206, when the upgrading type of defined this Set Top Box of standard information of mating is common upgrading type, whether (Software_update_section) function can eject dialog box prompting user by display needs upgrading.If the user selects upgrading, perform step 209 download upgrade datas; If the user selects to cancel upgrading, directly perform step 210, cancel upgrading.
Step 208, mandatory upgrade.
In step 206, when the upgrading type of defined this Set Top Box of standard information of mating is not common upgrading type, force set top box upgrading.And then perform step 209.
Step 209, download upgrade data, carries out software upgrading.
In the present embodiment, in step 207, the user selects to need upgrading trigger message in upgrading or step 208 to judge when the type of Set Top Box is mandatory upgrade, meets above promotion condition.In specific implementation, upgrade data information is by (Software_Data_Section ()) function representation, when step 208 and above step all meet promotion condition, the upgrading trigger message finds the place value of upgrade data information, and the value of showing (table_id) is 0x90.In transmission upgrade data information process, by the frequency point information PD in (Software_update_section) function, symbol rate indications FHL, and modulation system TZFS pins the frequency in transport stream TS stream.After pinning frequency, download table indications (table_id) corresponding with Set Top Box self type and upgrading type in (Software_Data_Section ()) function by the indications (download_table_id) of the download upgrade data table in (Software_update_section) function on the one hand.
