Electronic Program Guide (the Electronic Program Guide of tradition DVB service application, EPG) utilize the C language in set-top box, to realize, that is to say that TV programme list that the televiewer sees is along with the set-top box back of dispatching from the factory just specific represent form and exists with a kind of, conversion EPG's represents form if desired, can only be made into upgrading stream by front end system and issue set-top box then, set-top box loader program begins set-top box is upgraded after getting access to the upgrading descriptor.
Set-top box shows that the flow process of DVB may further comprise the steps:
1, set-top-box opening scans specific frequency;
2, the EIT table in the TS stream obtains EPG in the frequency by resolving;
3, set-top box interior tissue EPG, and by pre-set ways of presentation displaying.
Front end upgrading flow process may further comprise the steps:
1, gives loader manufacturer the file of needs upgrading, be made into the TS stream of upgrading usefulness by loader manufacturer;
2, send to the multiplexing TS stream of multiplexer by server (can be the EPG server);
3, the TS stream after the multiplexer handle is handled is issued modulator and is modulated;
4, be dealt into the subscriber computer top box flowing down at last.
The set top box upgrading flow process may further comprise the steps:
1, starts the loader program behind the set-top-box opening and check whether the upgrading descriptor is arranged;
If 2 have upgrade information then carry out set top box upgrading work, if not then normal boot-strap;
If 3 carry out upgrade job after, then need to restart the set-top box work of starting shooting normally then;
4, behind the normal boot-strap, the set top box upgrading success.
There is following shortcoming in present technical scheme:
1, set-top box can only offer self application by the EPG that TS stream parsing EIT table obtains, and this makes subsequent expansion and modification all will carry out program upgrade to set-top box.
2, because the upgrading of set-top box is to have very high riskly, and ROMPaq makes trouble, the frequent upgrading of set-top box is not allowed to.
3, upgrading is closely-related with the design of set-top box.If in set-top box flash, opened up description, then can carry out the part upgrading to the independent data of set-top box program; If no, then at every turn need be to the whole upgrading of set-top box.
If 4, set-top box can not local be upgraded, then improved the risk of set top box upgrading, if whole upgrading failure, set-top box just can not be used.
5, be subjected to the top-set hardware condition effect, can not provide the rich personality service for the user.
6, owing to have only start could trigger the loader ROMPaq, so each upgrading all is to need shut down to start shooting again, and user's machine open/close is uncontrollable, and most of user can not shut down in several months, so ROMPaq can't start sometimes.
7, TV user can not initiatively be initiated personalized service, and for example: template is replaced function.
Summary of the invention
