According to the invention, the radio and television station sends an emergency warning broadcast carrying an EWBS signal to the television, and the television in an emergency warning area plays the emergency warning broadcast carrying an EWBS signal to raise the alarm in advance and notice the audience, and therefore, the casualties and property loss are reduced.
Description
Technical field
The present invention relates to technical field of televising, particularly relate to a kind of method playing emergency alarm broadcast in TV.
Background technology
Due to earthquake, the disasters such as tsunami are more and more frequent, the loss produced is also increasing, so study and a kind of can receive the TV of warning information in signal, by the warning information in TV signal is informed spectators, give warning in advance, reduce casualties and property loss just becomes especially necessary and important.
Summary of the invention
For the weak point that prior art exists, it is an object of the invention to provide a kind of method playing emergency alarm broadcast in TV, by TV and Radio Service by the emergency alarm broadcast transmission with EWBS signal to TV, it is in the emergency alarm broadcast televised out with EWBS signal in emergency alarm region, give warning in advance and inform spectators, decreasing casualties and property loss.
The purpose of the present invention is achieved through the following technical solutions:
A kind of method playing emergency alarm broadcast in TV, TV has ISDB digital television system, it is characterized in that: include meteorological observatory, TV and Radio Service and TV, meteorological observatory sends weather alert to TV and Radio Service, the emergency alarm that TV and Radio Service sends with EWBS signal is broadcast to TV, EWBS signal is emergency alarm broadcast system signal, and television reception emergency alarm is broadcasted and play；Its concrete grammar is as follows:
A, the physical channel of reception, the detection emergency alarm broadcast singal with EWBS signal is set in the ISDB digital television system of TV, and the region code in area at TV is set in the ISDB digital television system of TV；
B, meteorological observatory send weather alert to TV and Radio Service, and TV and Radio Service is to the TV emergency alarm broadcast with EWBS signal, and emergency alarm broadcast includes the region code that wanted reminder alarm is regional；
C, television reception come from the broadcast of the emergency alarm with EWBS signal of TV and Radio Service, and region code regional with wanted reminder alarm for the region code in area at TV are contrasted, and whether both comparisons are identical；If identical, then entering step D, if it is not the same, then return step B, this emergency alarm broadcast do not play by TV；
D, emergency alarm of televising broadcast, sound the alarm or/and eject alert content.
The present invention is a kind of disaster alert early warning mechanism, especially region, South America or earthquake it are applied in, natural disaster takes place frequently area, in these regions, often there are the disasters such as earthquake in some country (such as Ecuador), if TV needs band EWBS function, before so disaster is arrived, meteorological observatory gives warning in advance, early warning information is sent to TV and Radio Service, TV and Radio Service makes the signal carrying EWBS, sent out by DTV signal, user's family television reception band EWBS signal, the AREACODE (i.e. region code) that contrast TV is arranged and AREACODE (i.e. region code) state parsed from signal, if it is inconsistent, continue detection；If it is identical, and it is currently holding state, then start shooting, and jump to the program with EWBS information, sound the alarm and warning information, if open state, leap to the program with EWBS information, sound the alarm and warning information, give warning in advance for user, win the quality time, reduce casualties and property loss.
In order to realize the present invention better, described step D specifically includes as follows:
If D1 TV is under ideal case, then TV Auto Power On, and it is switched to the corresponding program with warning information, then plays the emergency alarm broadcast with EWBS signal, sound the alarm or/and eject alert content；
If D2 TV is in open state, and actual program is not the program with correspondence warning information, then be switched to the program of corresponding warning information, then plays the emergency alarm broadcast with EWBS signal, sounds the alarm or/and eject alert content；
If D3 TV is in open state, and actual program is with corresponding warning information, then do not switch program, then plays the emergency alarm broadcast with EWBS signal, sounds the alarm or/and eject alert content.
Currently preferred technical scheme is as follows: it is as follows that the region code that in described step C, the region code in the present area of TV is regional with wanted reminder alarm carries out control methods:
C1, TV detect the digital signal in the physical channel of setting always, and TV carries out the B26 in numeral DEMO decoded digital signal TMCC；
C2, TV decoding B26 becomes 1 from 0, and the emergencyinformationdescriptor describing word in resolution digital signal pmt table if the region code that the region code parsed and TV are arranged differs, then returns to step B, if identical, then enters step D.
The present invention compared with the prior art, has the following advantages and beneficial effect:
The present invention passes through TV and Radio Service by the emergency alarm broadcast transmission with EWBS signal to TV so that is in the emergency alarm broadcast televised out with EWBS signal in emergency alarm region, gives warning in advance and inform spectators, decreasing casualties and property loss.
