Description
Technical field
The present invention relates to digital television techniques field, relate in particular to a kind of digital television terminal software upgrading method.
Background technology
Along with the particularly fast development of digital television techniques of science and technology, domestic Digital Television has entered Rapid development stage, at present, domestic each radio and TV operator is also actively carrying out Digital Television translation, and digital TV set-top box and digital TV integrated machine are the main terminal equipments of rating Digital Television.But, because the radio and TV operator of different regions requires to be not quite similar to the software function of Set Top Box or all-in-one, must there is for different radio and TV operator's exploitations the software of difference in functionality.Like this, even if the Set Top Box that the radio and TV operator of different regions selects or the hardware of all-in-one are identical, difference due to software aspect, Set Top Box or all-in-one producer also must produce Set Top Box or the all-in-one with same hardware and different software for different radio and TV operators, cannot there is for different radio and TV operator's large-scale production Set Top Box or the all-in-one of same hardware and same software, thereby cause Set Top Box or all-in-one manufacturer production flow process complicated, the problems such as production cost increase.
In order to solve the radio and TV operator of different regions, software function is required to inconsistent problem, Set Top Box or all-in-one producer can produce Set Top Box or the all-in-one with same hardware and same software for the radio and TV operator of different regions, Set Top Box or all-in-one are being delivered to after the radio and TV operator of different regions, by radio and TV operator, by digital television signal network, Set Top Box or all-in-one are carried out again the upgrading of corresponding software, but, at present to the method for Set Top Box or all-in-one software upgrading mainly: radio and TV operator is dealt into digital television signal network by upgrading traffic identifier and upgrading stream by dominant frequency program request by digital TV front-end, digital TV terminal is set the frequency (being dominant frequency point) at upgrading traffic identifier and upgrading stream place when dispatching from the factory, digital TV terminal is downloaded upgrading traffic identifier from dominant frequency point in the process of start, and judge whether that according to upgrading traffic identifier needing to download upgrading stream carries out software upgrading, and then complete software upgrading.Because different local radio and TV operators' dominant frequency point is also not quite identical, therefore, even if each operator requires in full accord to the hardware of Set Top Box or all-in-one and software function, consider the upgrade problem of subsequent software, Set Top Box or all-in-one producer still cannot large-scale production have Set Top Box or the all-in-one of same hardware and same software, or can cause Set Top Box or all-in-one manufacturer production flow process complicated, the problems such as production cost increase.
Application number is a kind of method that 200710186157.8 patent discloses updating set-top box software, disclose following technical characterictic: upgrade server front end adopts respectively two packet passages with fixed data Packet Identifier, at same frequency, broadcast upgrading stream and upgrading traffic identifier; Set Top Box detects the packet passage of the fixedly broadcasting upgrading traffic identifier of each frequency, the frequency that receives upgrading sign is used as to upgrade frequency point, and download ROMPaq in the packet passage flowing in the fixedly broadcasting upgrading of upgrade frequency point, completed the renewal of set-top box software.200710186157.8 number patent is not specified upgrade frequency point in set-top box software, but by frequency is one by one detected to whether have upgrading traffic identifier, and using the frequency that upgrading traffic identifier detected as upgrade frequency point, can solve a plurality of independently upgrade frequency point disunities between sub-operator, cannot use unified server to carry out the problem of software upgrading.But known according to the specification part of No. 200710186157.8 patents, the each start of Set Top Box all will detect each frequency, will cause set-top-box opening time lengthening; And the data that need always to detect the pid data bag of playing upgrading sign after set-top-box opening, increase resource overhead; In addition, No. 200710186157.8 patent has been specified the package identification symbol of upgrading traffic identifier with upgrading stream in set-top box software, when different regions operator for some reason cannot be when upgrade server front end be used the packet passage of the fixed data Packet Identifier of appointment in set-top box software, Set Top Box cannot be carried out software upgrading.Visible, No. 200710186157.8 patents also must be set for different radio and TV operators different upgrading traffic identifier and accord with the package identification of upgrading stream, the Set Top Box manufacturer production flow process complexity that exists equally Set Top Box producer to cause because producing for different radio and TV operators different Set Top Box, the problems such as production cost increase.
Summary of the invention
Object of the present invention is exactly the reasons such as software upgrading frequency disunity that require the radio and TV operator of incomplete same and different regions to set to the software function of Set Top Box or all-in-one in order to solve the current radio and TV operator because of different regions, and the Set Top Box causing or all-in-one producer must produce for different radio and TV operators different Set Top Box or all-in-one, make Set Top Box or all-in-one manufacturer production flow process complicated, the problems such as production cost increase, a kind of digital television terminal software upgrading method has been proposed, it increases a particular program information for describing upgrading flow identification information in program data by digital TV front-end, digital TV terminal is downloaded particular program information by program searching, and download upgrading traffic identifier according to particular program information, and then download upgrading stream according to upgrading traffic identifier, complete the upgrading of digital TV terminal software.It does not specify upgrade frequency point in digital TV terminal software, only need just can obtain particular program information by program searching, and then obtain upgrading traffic identifier and the relevant information of the stream of upgrading, realize the upgrading of digital TV terminal software, it makes digital TV terminal producer to produce the digital TV terminal with same hardware and software function for different radio and TV operators, simplified the production procedure of digital TV terminal producer, reduced production cost, the upgrading that realizes digital TV terminal software that can be convenient, flexible.
