1) cost height.Producer of every increase, Digital Television operation front end will increase by a cover set top box software updating equipment (server).
2) extendability is poor.Because the set top box software updating number of devices is uncertain, causes the front end system difficult design, extendability is poor.
3) poor stability is not easy to management.Because each set-top box producer adopts oneself independently set top box software updating equipment (server), TV station is wayward to the content code stream that set-top box producer generates.The pid value of the code stream that set-top box producer is generated is not easy to management.
4) operation inconvenience.Because the set top box software updating ASCII stream file ASCII is generally all very big, arrive between the hundreds of MB (megabyte) at tens MB (megabyte).Submission and backup are all very difficult like this, operation inconvenience.
Summary of the invention
The technical problem to be solved in the present invention is the method that proposes a kind of set top box software updating, the method of the invention does not need each set-top box producer to adopt oneself independently set top box software updating equipment, can guarantee the security that the set-top box manufacturer software upgrades again, and be convenient to digital-TV operator the software upgrading service is managed.
The technical scheme of the method for a kind of set top box software updating of the present invention is such: producer submits the software upgrading data file to, from the software upgrading data file that producer submits to, extract data message, and generate the ASCII stream file ASCII meet the DVB standard according to the pid value allocate file, playout software upgrades code stream, carries out software upgrading.
The method of aforesaid a kind of set top box software updating also comprises, before playout software upgrades ASCII stream file ASCII, earlier the ASCII stream file ASCII that generates is carried out the software upgrading test, and then plays the software upgrading code stream of testing.
The method of the invention has adopted a kind of data file that each producer submits the software upgrading data to that is used for, and this data file only comprises producer and wants data updated and corresponding information, rather than ASCII stream file ASCII.Therefore data file is less, arrives between several MB (megabyte) at hundreds of KB (kilobyte) usually, is convenient to submit to and backup.
Description of drawings
Fig. 1 is the method flow diagram of set top box software updating of the present invention;
Fig. 2 is the schematic flow sheet that software upgrading code stream of the present invention generates software.
Embodiment
