Television network broadcast; Broadcast in the process; In each DTV frequency code stream, insertion NIT table (network information table), BAT table (BAT bouquet association table), SDT show (SDT Service Description Table) and pmt table (Program Association Table) information through the digital TV front-end system in operator.Wherein, NIT table has been described the channel information that STB will scan, and like frequency frequency, symbol rate, modulation system etc., and searches the identifier of platform through the version number of self again as triggering STB; BAT shows, and has described the packet mode of channel; The SDT table has been described the channel Proprietary Information, like identifier, title, channel type etc.; Pmt table has been described the identifier and the stream type of the video-voice frequency flow of channel.
When operator need upgrade channel information, through the operation interface that the digital TV front-end system provides, the above table information in the change code stream; And change NIT simultaneously and show version number.STB no matter be in any service condition, all continues monitoring NIT table version number in the course of the work, changes in case find NIT table version number, will upgrade channel information according to following flow process:
1) locking dominant frequency point (this frequency is specified when STB dispatches from the factory) receives NIT table data, obtains the channel information of all radio and television;
2) receive BAT table data, obtain the grouping information of channel;
3) first frequency of locking NIT table appointment receives SDT table data, obtains the descriptor of the channel of this frequency;
4) receive pmt table, obtain the video/audio code stream information of this frequency channel;
5) second frequency of locking NIT table appointment repeats 3), 4) two steps, up to all radio and television frequencies of been scanned;
All information that 6) will get access to are kept in the Flash memory block of STB with the mode in SI database (service information data storehouse).
Through above-mentioned steps, STB can be accomplished the renewal of channel information.
Above-mentioned existing channel information update method; In its renewal process, no matter the user is using broadcasting service, demand (telecommunication) service or value-added service, and current business all need be interrupted; Thereby get into channel search interface or set top box upgrading program; It has interrupted user's current service, has influenced the service quality of operator, not enough hommization.And; When upgrading channel information, STB need lock the radio and television frequency one by one, receives the SI list data of broadcasting from each frequency; Use tens radio and television frequencies and generally run the commercial city; Each frequency point scanning all need be near one second time, and therefore once upgrading channel information needs very long half a minute to one minute even longer time; And when upgrading menu information, need restart STB twice, download and upgrade software upgrades the data among the FLASH, and therefore whole process needs the time of a few minutes at least, and it upgrades length consuming time, efficient is low.Have again; Existing method is when upgrading channel information, and data all are to be kept in the FLASH memory block of STB with binary mode, the protection mechanism that writes the shortage file of data; Easily because writing data makes mistakes and cause the FLASH memory block to be damaged, thereby cause set-top box failure.In addition, above-mentioned update method when upgrading channel information, needs the operation broadcasting system, and configuration SI data cause the accident of broadcasting easily; When upgrading menu information, need make set-top box software again, and software encapsulation is broadcast in TS code stream (transmitting stream), complex steps need expend the long period.
Summary of the invention
The present invention is intended to provide that a kind of update efficiency is high, safe and reliable, operation maintenance is convenient, and good STB channel information and the menu information update method of user experience.
STB channel information of the present invention and menu information update method comprise the steps:
The text that A, foundation comprise channel information and menu information is as configuration file;
B, front end system are broadcast profile data through object carousel mode (OC mode); And in the NIT of DTV frequency code stream table, insert the descriptor of describing configuration file, comprise the version number of configuration file and the data channel of download configuration file in the descriptor;
When C, configuration file renewal, the value of the configuration file version number in the corresponding change descriptor;
D, new configuration file is broadcast through object carousel mode (OC mode);
E, STB continue the value of the configuration file version number in the descriptor in the monitoring NIT table, in case the value of configuration file version number changes in the descriptor, then the data channel of the download configuration file through appointment is at the new configuration file of current frequency download;
F, the new original configuration file of configuration file mulch-laying machine top box that will download, STB reads configuration file, thereby upgrades channel information and menu information.
STB channel information of the present invention and menu information update method; It has set up and has broadcast the configuration file of the text form that comprises channel information and menu information at front end system; When channel information and menu information need change; Front end system is revised new configuration file, and its mode with object carousel (OC mode) is broadcast; And the value of the configuration file version number in the descriptor of the description configuration file that in the NIT table that changes at DTV frequency code stream, inserts simultaneously.STB is then monitored the value of the configuration file version number in the descriptor in the code stream, in case change, promptly fixs through the descriptor middle finger that the passage that carries configuration file is downloaded new configuration file and with its cover original configuration file; STB reads configuration file afterwards, thereby has realized the renewal of STB channel information and menu information.In the renewal process of its STB channel information machine menu information; Detect renewal, file in download, write operation such as overlay file and all carry out on the backstage, the user need not interrupted current business, can continue current service; The user uses unaffected, and user experience is good.Simultaneously; Its renewal process is merely the download and the overwrite procedure of the configuration file of text form; STB when the scanning one by one of the frequency when not needing the information updating of prior art mid band is upgraded with menu information restarts, the data in download and upgrade software and the renewal FLASH holder, and its whole renewal speed is fast, weak point consuming time; Stand-by period of user has greatly been shortened in several completion in several seconds.In addition; Configuration file is through the data in the file new mechanism FLASH memory, (as: STB uses linux operating system, the file mechanism through Linux to the preservation of configuration file, duplicate, move, deletion action; Can realize through the general file handling function that linux operating system provides); Security of system is high, is beneficial to the life-span that prolongs STB, reduces the failure rate of STB.In addition; Channel information update method of the present invention uses the configuration file mode to upgrade channel information, only need revise configuration file content through text edit software and get final product; It upgrades channel information need not operate broadcasting system and configuration SI database, can therefore not cause the accident of broadcasting; Upgrade menu information and need not make set-top box software, also do not exist set-top box software is encapsulated in the problem of broadcasting in the TS code stream, it had both improved efficiency of operation, reduced maintenance cost again.
