Abstract
The invention discloses a method for setting a centre frequency of a set top box in a terrestrial digital television multi-frequency network, and relates to the field of electronic program guides (EPG) of terrestrial digital televisions and the field of terminals. The method comprises the following steps that: a set top box of a terrestrial digital television is incapable of realizing value added services by setting a fixed centre frequency at the front end in a unified manner due to different frequencies of various areas in a multi-frequency network; a specific convention mark is made to an Service Provider in an SDT (Service Description Table) at the front end; the terminal sets the frequency, where a programme having the convention mark is, as the centre frequency while searching the programme; or else, the terminal does not set the frequency; and thus, the centre frequency of the multi-frequency network is set.
Description
Technical field
The present invention relates to terrestrial DTV electronic program guides (EPG) field and terrestrial DTV field of terminal.By EPG system front end and terminal arrange SDT show in " ServiceProvider " identify, analyze when terminal is at searching programs agreement mark time this frequency is set to centre frequency; When the program in multiple frequency has an agreement mark to give tacit consent to frequency centered by last frequency.
Background technology
Multiple frequency network, MFN is networking mode common in terrestrial DTV, particularly in the provincial terrestrial DTV network or national terrestrial DTV network of front end unification.Because the difference of various places Web vector graphic frequency uses the business of centre frequency to bring impact on needing, some business are carried out owing to there is no centre frequency inconvenience.
Electronic program guides (electricalprogramguide is called for short EPG) is the english abbreviation of ElectronicProgramGuide; It provides a kind of easy use, friendly interface, can want to see the mode of program by fast access for user, and user can see by this function the TV programme that the even all channels of one or more channel will be play in the recent period.Basic electronic program guides comprises the network information, bouquet information, business description information, event information.SDT table and business description information, comprise the description to type of service, service provider, Business Name.
Summary of the invention
The object of the invention is to a kind of method designing terminal profile centre frequency in terrestrial DTV multiple frequency network, MFN: the method describes mark by analyzing " ServiceProvider " in SDT table when searching programs, when identical with the mark that terminal is arranged, terminal preserves actual program place frequency information, and is set to centre frequency; Frequency centered by mark of having an agreement for the last time is given tacit consent to when having an agreement and identify in the SDT table in multiple frequency.
The present invention has following beneficial effect: for terrestrial DTV multiple frequency network, MFN provides a kind of method arranging centre frequency, solves the obstacle of the transfer of data such as EPG advertisement, terminal staging, stock information, is conducive to carrying out of more value-added services.
For reaching this object, the present invention by the following technical solutions:
A method for Set Top Box setting centre frequency in terrestrial DTV multiple frequency network, MFN, comprises the following steps:
A, show to insert the mark appointed with terminal in " ServiceProvider " at the SDT of front end EPG;
B, terminal searching program;
C, terminal analysis search in SDT table " ServiceProvider " of program whether have the mark of arranging with terminal;
The program place frequency that " ServiceProvider " in SDT table has agreement mark is set to centre frequency by D, terminal, does not arrange the only preservation program identified;
E, the search carrying out next frequency program or termination program searching.
Steps A is further comprising the steps:
SDT table in EPG system can be edited, and can insert the mark appointed with terminal in " ServiceProvide ";
In SDT table in the multiplexer can editing SI information or scrambling machine, " ServiceProvide " inserts the mark appointed with terminal;
The mark of agreement is not limited to Chinese character, Chinese pinyin, English capitalization, english lowercase etc.;
Search package is containing standard video-audio program, standard audio broadcast program etc.
Step B is further comprising the steps:
Terminal program search does not adopt NIT to show way of search;
Terminal has full frequency band search and assigned frequency searching programs function.
Step C is further comprising the steps:
Analyze SDT table to refer to and searched for a frequency or multiple frequency when full frequency band searching programs in order or all carried out after frequency;
SDT table is analyzed when assigned frequency searching programs completes.
Step D is further comprising the steps:
Show when only there being the SDT of partial programme in the frequency searched to have an agreement in " ServiceProvide " when describing mark and be also set to centre frequency.
Accompanying drawing explanation
Fig. 1 is the workflow diagram setting centre frequency in the specific embodiment of the invention.
Embodiment
Technical scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing; obviously; described embodiment is only the present invention's part embodiment; instead of whole embodiment; based on the embodiment in the present invention; those of ordinary skill in the art, in the every other embodiment not having to obtain under creative work prerequisite, belong to the scope of invention protection.
Fig. 1 is the workflow diagram setting centre frequency in the specific embodiment of the invention, if Fig. 1 is as shown, EPG system or have SI editting function other equipment such as front end multiplexer, scrambling machine SDT table in " ServiceProvider " insert " HNMTV-NX " and arrange come into force.
At terminal full frequency band searching programs or assigned frequency searching programs.
Terminal searched for a frequency or multiple frequency or all frequency time analyze SDT table.
The program place frequency having " HNMTV-NX " to identify in SDT table " ServiceProvider " is preserved and is set to centre frequency by terminal, does not have the frequency identified only to preserve program.
Frequency centered by the frequency of terminal mark of having an agreement that acquiescence searches for the last time when the SDT searching multiple frequency shows to have an agreement description mark in " ServiceProvider ".
Terminal proceeds the search of next frequency program or terminates program searching.
The above; be only the execution mode that invention is preferably concrete; but protection scope of the present invention is not limited thereto; any people being familiar with this technology is in the technical scope disclosed by the present invention; the change that can expect easily or replacement; all should be encompassed within protection scope of the present invention, therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
