Channel information and menu information updating method of set-top box

Abstract

The invention discloses a channel information and menu information updating method of a set-top box. The channel information and menu information updating method of the set-top box includes: establishing and broadcasting a configuration file which is in the text file form and includes channel information and menu information through a front-end system, modifying the configuration file when the channel information and the menu information change, and broadcasting the modified configuration file by means of object carousel; and changing the value of a configuration file version number in a descriptor which is used for describing the configuration file and is interpolated into an NIT (network information table) of a digital television frequency point bit stream, using the set-top box to monitor the value of the configuration file version number in the descriptor in the bit stream, and downloading a new configuration file through a designated download channel to overlay the original configuration file once the value changes, so that the channel information and the menu information of the set-top box are updated. The channel information and menu information updating method of the set-top box is high in updating efficiency, safe, reliable and convenient to operate and maintain, and user experience is good.

Description

technical field [0001] The invention relates to a method for updating channel information and menu information of a set-top box in a broadcast television network. Background technique [0002] Broadcasting and TV network, during the broadcasting process, the operator inserts the NIT table (network information table), BAT table (business group association table), SDT table (service description table) into each digital TV video stream through the digital TV front-end system ) and PMT table (program association table) information. Among them, the NIT table describes the channel information to be scanned by the set-top box, such as frequency point frequency, symbol rate, modulation mode, etc., and uses its own version number as an identifier to trigger the set-top box to re-search channels; the BAT table describes the grouping of channels Mode; SDT table, which describes channel-specific information, such as identifier, name, channel type, etc.; PMT table, which describes the ...

Problems solved by technology

[0011] In the above-mentioned existing channel information update method, during the update process, no matter the user is using the broadcast service, on-demand service or value-added service, the current service needs to be interrupted, thereby entering the channel search interface or the set-top box upgrade program, which interrupts the user's current service, Affected the service quality of operators, not humanized enough

Moreover, when updating channel information, the set-top box needs to lock the broadcast TV frequency points one by one, and receive the broadcast SI form data from each frequency point, while the general operator uses dozens of broadcast TV frequency points, and each frequency point scan needs to be close to One second, so it takes half a minute to one minute, or even longer, to update the channel information once; and when updating the menu information, it needs to restart the set-top box twice, download the upgrade software, and update the data in the FLASH, so the entire The process takes at least several minutes, and its update is time-consuming and inefficient

Have again, existing method is when updating channel information, and data all is to be stored in the FLASH memory area of ​​set-top box with binary mode, and the write-in of data lacks the protection mechanism of file, easily causes FLASH memory area damage because of writing data mistake , causing the set-top box to malfunction

In addition, in the above update method, when updating channel information, it is necessary to operate the broadcasting system and configure SI data, which may easily cause broadcasting accidents; when updating menu information, it is necessary to recreate the set-top box software and package the software in TS code stream (transport stream). Broadcasting, the steps are cumbersome and take a long time
