Background technology
TV user in life, the TV programme seen, in the technology of TV station, belong to the data (comprising sound and picture) of audiovisual presentation layer, due in TV programme monitoring, this link directly has influence on the view reception effect of end user, thus most important.Dissimilar TV programme, through different data channel and equipment, and no matter on link, which equipment breaks down, and all can cause the exception of image layer, thus the monitoring of image layer is not only important, and complicated.
Traditional fault alarm mainly contains " black field ", " quiet frame ", " noiseless " three major types is reported to the police, and in addition, what directly have influence on TV user watched effect also has the phenomenon such as " mosaic ", " tie rod ".Latter two image failure has a strong impact on broadcast quality, but its detection method is very complicated.Mainly contain following several reason: 1, program scene inherently likely people for producing above-mentioned phenomenon, such as, in the scene of some TV programme, also can deliberately to the overall situation or part local carry out mosaic processing; For another example some TV play can make partial programme replay, and identify human failure, also makes mosaic and Caton phenomenon check processing difficulty greatly strengthen.2, all judgements, all can not independent judgment, needs comprehensively to judge in conjunction with whole screen.The difficult point detected as mosaic is in units of region, only to consider local, and want global planning to consider.Such as, on screen large stretch of redness, can not be considered as red mosaic phenomenon.
For the problems referred to above, if do not have a set of good judgment mode, then result or wrong report are too much, or detect not out.The phenomenon such as " mosaic ", " tie rod " does not also have a set of effective algorithm at present, can be applied in the program monitoring of TV station.
Summary of the invention
The object of the invention is for deficiency of the prior art, the RM of a kind of audio frequency and video mosaic and tie rod fault is provided.
For achieving the above object, the technical scheme that the present invention takes is the RM of a kind of audio frequency and video mosaic and tie rod fault, it is characterized in that, comprises the following steps:
Step a, introduces the step of 2 tunnels and above identical signal simultaneously;
Step b, preset two class values, a class be some fixed sizes region in degree of approximation lower limit; Another kind of is the step of total degree of approximation lower limit of full frame or full frame participation comparison domain;
Step c, to the signal introduced, carry out the contrast between video between any two, and produce each region degree of approximation and full frame approximate angle value in real time, the degree of approximation evaluation algorithm of the two can be different, prescribe a time limit under the default degree of approximation when each entry value is less than in step b, be considered as " difference ", otherwise be then considered as the step of " identical ";
Steps d, when full frame value " identical " in " step c ", analyzes the distribution of each region " identical " value, if discrete distribution, be then considered as " mosaic " fault; If the distribution of horizontal and vertical strip, be then considered as " tie rod " fault; Otherwise be considered as the step of other fault alarms.
Introduce 2 road algorithms in step a to be with the difference introducing multichannel algorithm, the recombinant of multichannel algorithm judges the accuracy only increasing application, and do not change the accuracy of algorithm itself, therefore 2 road algorithms should be considered as identical with multichannel algorithm.
The invention has the advantages that:
1, the RM of a kind of audio frequency and video mosaic of the present invention and tie rod fault, can identify " mosaic " and " tie rod " fault effectively, and can filter wherein that people is " mosaic " and " tie rod " fault added because the scene of program own needs.
2, the RM of a kind of audio frequency and video mosaic of the present invention and tie rod fault, for artificial mosaic and tie rod (mosaic namely occurred in scene and tie rod), there is good shielding action, for the false-alarm solving mosaic and tie rod in mute video provides good Theory and applications basis.
Accompanying drawing explanation
Accompanying drawing 1 is the RM flow chart of a kind of audio frequency and video mosaic of the present invention and tie rod fault.
Embodiment
Below in conjunction with accompanying drawing, embodiment provided by the invention is elaborated.
As shown in Figure 1, the RM of a kind of audio frequency and video mosaic and tie rod fault, is characterized in that, comprise the following steps:
Step a, introduces the step of 2 tunnels and above identical signal simultaneously;
Step b, preset two class values, a class be some fixed sizes region in degree of approximation lower limit; Another kind of is the step of total degree of approximation lower limit of full frame or full frame participation comparison domain;
Step c, to the signal introduced, carry out the contrast between video between any two, and produce each region degree of approximation and full frame approximate angle value in real time, the degree of approximation evaluation algorithm of the two can be different, prescribe a time limit under the default degree of approximation when each entry value is less than in step b, be considered as " difference ", otherwise be then considered as the step of " identical ";
Steps d, when full frame value " identical " in " step c ", analyzes the distribution of each region " identical " value, if discrete distribution, be then considered as " mosaic " fault; If the distribution of horizontal and vertical strip, be then considered as " tie rod " fault; Otherwise be considered as the step of other fault alarms.
Introduce 2 road algorithms in step a to be with the difference introducing multichannel algorithm, the recombinant of multichannel algorithm judges the accuracy only increasing application, and do not change the accuracy of algorithm itself, therefore 2 road algorithms should be considered as identical with multichannel algorithm.
It should be noted that: " region " that the present invention mentions draws look, can with reference to the division of MPEG2 and H.264 algorithm, generally (but being not limited to) divides with 16 × 16 pixels.In fact, this is also under normal circumstances, and encoder produces the division of mosaic and tie rod fault.Meanwhile, the present invention, for artificial mosaic and tie rod (mosaic namely occurred in scene and tie rod), has good shielding action, and this is that the false-alarm problem solving mosaic and tie rod in mute video provides good Theory and applications basis.
The principle that the present invention relies on is: mosaic or tie rod fault appear in two paths of signals simultaneously, and the mosaic probability all identical with type with the position that tie rod occurs is small probability event.Illustrate as follows: suppose that the rate of failure of certain TV station's equipment or signal is 1 year 1 time, each processing time, the interval upper limit was 1 minute, then the probability broken down in certain 1 minute is (365*24*60)
-1=525600
-1, the while that two completely independently signal being in certain 1 minute, the concept of mitogenetic fault is 525600
-2, oppositely calculate, be 520,000 years once.In like manner, the while that three completely independently signal being in certain 1 minute, the concept of mitogenetic fault is 525600
-3, oppositely calculate, be 2,762 hundred million once.As can be seen here, two-way and above independent signal occur that the probability of same fault is small probability event simultaneously.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the inventive method; can also make some improvement and supplement, these improve and supplement and also should be considered as protection scope of the present invention.
