Description
Technical field
The present invention relates to a kind of broadcast monitor message and select filter method, is a kind ofly to guarantee that TV station is to broadcast program broadcasting signal normal and broadcast safe method.
Background technology
Broadcasting the Stability and veracity of supervisory control system, is that whole broadcast system is realized the basis of detecting.In broadcast system, often for the consideration of safety factor, for the problem occurring in signal, to all report entirely, avoid failing to report, the warning sensitivity of the necessary raising signal detection apparatus of like this making use of momentum.
TV station's broadcast system generally adopts Miranda KX multi-image divider as the signal monitoring equipment of broadcast system.This kind equipment has just been adhered to the high characteristic of said warning sensitivity above: as long as the broadcasting signal of monitoring has, extremely all can unconditionally quote, certainly he can filter according to the length of duration the warning of oneself, even but so still there are two problems below:
1. because TV station's broadcasting signal source has a plurality ofly, and just broadcasting programme signal source, only have one, when so non-other signal sources of just broadcasting signal are abnormal, also can report to the police;
2. some is just broadcasting the situation that has some special scenes in program, and some of signal is to determine due to scene characteristics that program itself exists extremely.Such as dumb show does not have sound, many pictures can all be quoted audible alarm.
If these warnings do not add processing and all quote to cause excessive wrong report information, will obscure the judgement that together affects operator on duty with those useful warnings, make people in a large amount of warning messages, be difficult to distinguish real warning message.
Summary of the invention
For solving the problem of technology in existing scheme, the present invention proposes a kind of broadcast monitor message and selects filter method.It is foundation that described method be take programme and skill document examination, and some modal wrong report possibilities are analyzed, and filters unnecessary warning message, and warning message amount is down to minimum.
The technical solution used in the present invention is: a kind of broadcast monitor message is selected filter method, the hardware system that described method is used comprises: video server, cut bank and the emergent PGM of switching, downconverter that original monitored information is provided to multi-image divider, the MQ server, broadcast Monitor Daemon Server, broadcast database server, monitoring acquisition server, monitoring database server, monitoring convergence server, the monitor client work station that from broadcasting higher level's machine, receive skill document examination and programme, the step of described method is as follows:
Guarantee programme and the correct step of skill document examination: for " monitoring acquisition server " before starting broadcasting, to " broadcast Monitor Daemon Server ", confirm that programme is the correct programme of this channel, and the confirmation skill document examination information corresponding with each program file in described programme;
Programme start-stop is broadcast the step of filtration: the alarm signal of getting rid of the vacant time between two programmes for monitoring acquisition server;
The step that programme signal source is filtered: for monitoring acquisition server according to the signal source type of the current programme entry of broadcasting, the warning of non-this signal source type is all filtered and neglected, no longer report to the police;
The step of programme keyword filtration: for after certain several word being configured to some monitoring attributes of the program entries of certain signal source type and not reporting to the police; when monitoring acquisition server finds that in programme, current broadcast items is this signal source type; and during the program that clause name comprises these words; while detecting the fault of attribute if there is pre-configured this, neglect this fault message, no longer report to the police;
The step of sound channel alarm filter: get rid of unnecessary alarm signal according to the sound type of current broadcast items and sound source for monitoring acquisition server;
The step of skill document examination alarm filter: for monitoring acquisition server according to " the quiet frame " that record in the skill document examination of the program broadcasting, " black ", " quiet " information, the corresponding fault alarm item occurring in this program broadcast process is filtered and neglected, no longer report to the police; Simultaneously for unwritten fault message Normal Alarm.
The beneficial effect that the present invention produces is: in order to guarantee to broadcast normally, each channel has operator on duty to pay close attention to constantly the whether normal of broadcasting signal, if like this, safe broadcast is larger for personnel's dependence, when operator on duty has fatigue or carelessness unavoidably.In order to make up operator on duty, there is carelessness, signal monitoring has been done dual fail-safe to normal broadcast technically, signal monitoring is exactly mainly the monitor state of signal is passed through to vision, the mode of the sense of hearing represents, when occurring that signal is abnormal, software can be reminded in time operator on duty's coherent signal to go wrong and need to solve in time.
If these warnings do not add processing, all do not quote, will obscure the judgement that together affects operator on duty with those useful warnings.So, in TV station's broadcast system, be starved of a kind of tactful supervisory control system that possesses monitor message selection filtration and be used for assisting broadcast safety.Supervisory control system is obtained all the time to broadcast and is broadcast list the first month of the lunar year, according to up-to-date programme trap signal, reports to the police, and there will not be wrong report or fails to report.The present invention utilizes a plurality of factors such as skill document examination, keyword, sound, the alarm signal that all monitoring systems are quoted is filtered, the quantity of alarm signal is greatly reduced, monitor staff can concentrate one's energy to process a small amount of alarm signal after filtering, avoid, because error is processed in warning tired and that carelessness causes, guaranteeing to broadcast normal;
First the step of described sound channel alarm filter obtains the channel type of current broadcast items for monitoring acquisition server by programme, channel type is: a kind of in monophony, stereo, surround sound; Follow-uply comprise that following order in no particular order can parallel sub-step of carrying out: the signal gathering from video server output is filtered:
When if monitoring acquisition server is the program of monoaural type for current broadcast items: have sound if monitoring acquisition server detects 1 sound channel, whether other sound channels have sound not report to the police; If monitoring acquisition server detects 1 sound channel, there is no sound, no matter whether other sound channels have sound all to report to the police;
When if monitoring acquisition server is the program of stereo type for current broadcast items: have sound if monitoring acquisition server detects 1,2 sound channels, other sound channels there are not sound not report to the police yet; If monitoring acquisition server detects 1,2 sound channels, have a sound channel not have sound or two sound channels all there is no sound, whether other sound channel has sound all to report to the police;
When if monitoring acquisition server is the program of surround sound type for current broadcast items: have sound if monitoring acquisition server detects 7,8 sound channels, 1,2,3 sound channels have had a sound channel to have sound or a plurality of sound channel to have sound,, for some the sound channel voiceless sound in 1,2,3 sound channels or the asonant situation of other sound channels, just need not report to the police; If acquisition server detects in 7,8 sound channels, have a sound channel or two sound channels there is no sound, or three sound channels of 1,2,3 sound channels all do not have sound simultaneously, whether other sound channel has sound all to report to the police;
To gathering the signal of autotomy zapping and the emergent PGM of switching output, filter:
When if monitoring acquisition server is the program of monophony or stereo type for current broadcast items: have sound if monitoring acquisition server detects 1,2,7,8 sound channels; Other sound channels there are not sound not report to the police yet; As long as have a sound channel there is no sound if monitoring acquisition server detects in 1,2,7,8 sound channels, whether other sound channel has sound all to report to the police;

Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the system schematic that method is used described in the embodiment of the present invention one;
Fig. 2 is the theory diagram of method described in the embodiment of the present invention one.
Embodiment
Embodiment mono-:
The present embodiment is that a kind of broadcast monitor message is selected filter method.The hardware system that the present embodiment is used comprises: video server, cut bank and the emergent PGM of switching, downconverter that original monitored information is provided to multi-image divider, from broadcasting higher level's machine, receive MQ server, broadcast Monitor Daemon Server, broadcast database server, monitoring acquisition server, monitoring database server, monitoring convergence server, the monitor client work station of skill document examination and programme, as shown in Figure 1.
Video server described in the present embodiment, cut bank and emergent switching PGM, downconverter are the very important equipment of three classes in normal broadcast system, whether their video and audio output signal is normally to monitor at any time, multi-image divider mainly detects the output signal of this three kind equipment, and sends original alarm signal.The present embodiment is mainly analyzed the given original alarm signal of multi-image divider, gets rid of alarm signal unnecessary in original alarm signal, and the alarm signal that defines use is offered to monitor client work station.
Described in the present embodiment, the step of method is as follows:
Guarantee programme and the correct step of skill document examination: for " monitoring acquisition server " before starting broadcasting, to " broadcast Monitor Daemon Server ", confirm that programme is the correct programme of this channel, and the confirmation skill document examination information corresponding with each program file in described programme.First obtain and broadcast up-to-date programme:
1. monitoring loads programme and skill document examination:
When monitor service starts, each is monitored acquisition server and can whereabouts broadcasts Monitor Daemon Server and ask for each channel program list in institute's compass of competency separately, broadcast Monitor Daemon Server is inquired about each programme to broadcast database server and is returned to monitoring acquisition server, and monitoring acquisition server deposits monitoring database server in.And start to implement filtration measure according to this programme.
2. the last confirmation of skill document examination:
In programme, material is to while starting broadcasting time the first two hour, monitoring acquisition server can be inquired about the up-to-date skill document examination of each program institute respective file by whereabouts broadcast Monitor Daemon Server every five minutes, return to monitoring acquisition server, monitoring acquisition server deposits monitoring database server in.And start to implement filtration measure according to this skill document examination.
3. broadcast and revise programme and skill document examination:
When broadcasting subordinate's machine or higher level's machine maintenance while having changed programme and skill document examination, send a notification message (channel id+ date) to broadcast Monitor Daemon Server, broadcast Monitor Daemon Server and receive after this MQ message (programme change message), message is transmitted to and respectively monitors acquisition server.Monitoring acquisition server is asked for up-to-date programme and skill document examination to broadcasting Monitor Daemon Server again, broadcast Monitor Daemon Server and inquire about up-to-date programme and skill document examination to broadcasting in database server, and return to monitoring acquisition server, monitoring acquisition server upgrades programme and the skill document examination of broadcasting in database server, and starts to implement filtration measure according to new programme and skill document examination.
Programme start-stop is broadcast the step of filtration: the alarm signal of getting rid of the vacant time between two programmes for monitoring acquisition server.When the end time of last programme and next starting broadcasting of a programme between the time, have in the situation in space, without any broadcasting signal, so monitoring acquisition server all filters out the warnings of all relevant signals during this period of time.For example: the programme end time on certain channel same day is 05:00:00:00, the programme time of starting broadcasting of second day is 06:00:00:00, at 05:00:00:00---in the time of this hour between 06:00:00:00, the signal alarm of this channel all filters out.
The step that programme signal source is filtered: for monitoring acquisition server according to the signal source type of the current programme entry of broadcasting, the warning of non-this signal source type is all filtered and neglected, no longer report to the police.For example: certain programme is at 10:00:00:01---11:30:00:00, what during this period of time, broadcast is the program that signal source type is " video server ", and the interior alarm signal about non-" video server " signals such as " line signals " all filters out during this period of time.
The step of programme keyword filtration: for after certain several word being configured to some monitoring attributes of the program entries of certain signal source type and not reporting to the police, in the programme of monitoring acquisition server, current broadcast items is this signal source type, and during the program that clause name comprises these words, while detecting the fault of attribute if there is pre-configured this, neglect this fault message, no longer report to the police.For example: " resolution chart " two words are set to when the entry that signal source type is " video server " is play, and its alarm filters out.When playitem name be called " ... resolution chart ... " program time (and its signal source type is " video server "), its alarm is filtered out.The step of sound channel alarm filter: get rid of unnecessary alarm signal according to the sound type of current broadcast items and sound source for monitoring acquisition server.In type of alarm, also comprise a kind of warning of audio frequency, audio frequency comprises 8 sound channels, monitoring system can not have certain or some sound channels the signal of sound all as abnormal alarm, to process, but in fact the audio frequency of program often can't be used 8 sound channels, some sound channel is output sound not, and the mode that does not process so direct warning just there will be the situation of wrong report.
The sound type of program comprises three kinds: monophony, stereo, surround sound.
Broadcasting on link, many pictures are provided with monitoring point in three places: signal source (video server signal), cut bank and the emergent PGM(PGM that switches: just broadcasting entry), after down conversion.According to the difference of broadcasting each monitoring point on link, also specifically divided " signal source ", " cut bank and the emergent PGM of switching ", " after down conversion " three kinds of different warning processing modes:
