Abstract
The method includes three components: rules and procedures for determining software update condition, attribute field of set-top box needed by determining procedures, and attribute field of operation manager needed by determining procedures. Descriptor of software update condition for set-top box composed of the attribute field of set-top and the attribute field of operation manager are broadcasted by front end of digital TV set circularly. After receiving descriptor of software update condition, the set-top box uses information of attribute field self stored, and information of attribute field in IC card to determine whether self satisfies the software update condition based on rules for determining software update condition or not; if not, then exiting from the current procedure, and returning back to previous running state; otherwise, continuously carrying out next software update condition based on upgrading type pointed in conditional descriptor.
Description
Technical field
The invention belongs to the digital television broadcasting field, be specifically related to the condition judging method in a kind of digital television set top box software updating system.
Background technology
Digital television techniques is the new technology of radio and television, and it adopts digital signal to replace analog signal to come transmitting television program.In digital television system, user side need use set-top box to receive the digital television program of being broadcast by front end.When there is defective in the software in operator's increase Digital Television new business or the set-top box, need the software in the set-top box be upgraded, renewal process is to be finished by the software update system of set-top box.A complete set top box software updating process is as described below:
1) digital TV front-end broadcast (sites) in turn update software data flow and corresponding with it set top box software updating condition descriptor in transport stream;
2) after set-top box receives software upgrading condition descriptor, judge according to decision rule whether oneself satisfies update condition, if satisfy then receive the update software data flow;
3) after set-top box receives the update software flow data and finishes, software data is verified, checking by after can begin to carry out the software refreshing process, until finishing.
Wherein, set top box software updating condition descriptor is used for carrying the condition of software upgrading, and the software data stream and the executive software that promptly have only the set-top box that satisfies these conditions just can download will to upgrade upgrade operation.
Software refreshing is meant that set-top box writes process in the internal repository with downloaded software, promptly uses newly downloaded software to cover original software.
What above-mentioned steps 2) describe is exactly condition criterion process in the set top box software updating system, condition judging method has important function in digital television set top box software updating system, the digital-TV operator that can help perfect update software condition judging method realizes under the complex situations the effective enforcement and the management of set top box software updating such as (for example multistage operation, the many districts and cities of front-end platform shared), guarantees that operator carries out software upgrading to affiliated subscriber computer top box safely and reliably.
Summary of the invention
The object of the present invention is to provide the condition judging method in a kind of digital television set top box software updating system, this condition judging method has logic manage level clearly, can help digital-TV operator to realize under the complex situations the effective enforcement and the management of set top box software updating such as (for example multistage operation, the many districts and cities of front-end platform shared), guarantee that operator carries out software upgrading to affiliated subscriber computer top box safely and reliably.
Condition judging method in a kind of digital television set top box software updating system provided by the invention, it is characterized in that digital TV front-end circulation broadcasting set top box software updating condition descriptor, this condition descriptor comprises field contents as described below: Manu_code, HW_Version, Major_HW_version, Minor_HW_version, HW_Batch_No, Version_number, Region_Code_Start, Region_Code_End, Operator_Code, Upgrade_type, STB_Sequence_Start, STB_Sequence_End, after set-top box receives the condition descriptor, utilize the attribute field information of self preserving and the attribute field information in the IC-card, judge according to software upgrading condition criterion rule whether self satisfies the software upgrading condition, turn back to running status before if do not satisfy then withdraw from active procedure, otherwise continue to carry out ensuing software upgrading process according to the upgrading type of appointment in the condition descriptor.
The field contents that above-mentioned condition descriptor comprises is defined as follows:
Manu_Code: set-top box vendor code;
HW_Version: top-set hardware version information;
Major_HW_version: the top-set hardware key plate originally;
Minor_HW_version: top-set hardware time version;

Condition judging method in the digital television set top box software updating system provided by the invention specifically comprises following steps:
(1) set-top box judges whether the Manu_code field value in self Manu_code field value and the software upgrading condition descriptor mates, and does not then withdraw from the software upgrading process if match, state before turning back to, otherwise continue to carry out the judgement of back;
(2) set-top box judges whether the same field in self HW_Version field value or Major_HW_version field and Minor_HW_version field value and the software upgrading condition descriptor mates, then do not withdraw from the software upgrading process if match, state before turning back to, otherwise continue to carry out the judgement of back;
(3) set-top box judges whether the HW_Batch_No field value in self HW_Batch_No field value and the software upgrading condition descriptor mates, and does not then withdraw from the software upgrading process if match, state before turning back to, otherwise continue to carry out the judgement of back;
(4) set-top box judges whether the Version_number field value in self Version_number field value and the software upgrading condition descriptor mates, and does not then withdraw from the software upgrading process if match, state before turning back to, otherwise continue to carry out the judgement of back;
(5) set-top box judges whether Region_Code field value in the IC-card drops within the scope of Region_Code_Start field value and Region_Code_End field value in the software upgrading condition descriptor, if in scope then continue to carry out the judgement of back, otherwise withdraw from the software upgrading process, state before turning back to;
(6) set-top box judges whether the Operator_Code field value in the Operator_Code field value and software upgrading condition descriptor mates in the IC-card, does not then withdraw from the software upgrading process if match, state before turning back to, otherwise continue to carry out the judgement of back;
(7) set-top box is determined updating type according to the Upgrade_type field value in the software upgrading condition descriptor, and whether the STB_Sequence field value of judging self is in the scope of the STB_Sequence_Start of updating type agreement and STB_Sequence_End field value, if in scope, then set-top box is carried out the software upgrading operation of respective type, otherwise withdraw from decision process and turn back to state before.
Each field and decision rule are defined as follows in the above-mentioned steps:
Manu_code: the set-top box vendor code, distribute to each producer's unique value by operator; The Manu_code field value that satisfies in the set-top box of promotion condition will mate mutually with the Manu_code field value that condition is upgraded in the descriptor;
