Embodiment
A lot of details have been set forth in the following description so that make much of the present invention.But the present invention can implement much to be different from alternate manner described here, and those skilled in the art can do similar popularization under the situation of intension of the present invention, so the present invention does not receive the restriction of following disclosed practical implementation.
Do detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
As shown in Figure 1, in one embodiment of the invention, provide according to play content and carry out the information push method, the method comprising the steps of:
S101, displaying video in first viewing area of television set or display;
S102 obtains the information of said video;
S103 confirms pushed information according to the information of said video;
S104 is presented at pushed information in second viewing area of television set or display.
In step S101, the video of being play by television set or display can be the TV programme from cable TV network or wireless videocast.The signal of these programs can insert from television set and not change existing TV signal access way.
In step S102, the information of obtaining video comprises television channel, television programme title and/or programme content etc.Wherein, as shown in Figure 2, the method for obtaining television channel or television programme title specifically can comprise step:
S1021 obtains the sectional drawing of the video of being play in first viewing area;
S1022 confirms the information matches zone in the sectional drawing of video, perhaps intercepting message coupling map-area from the sectional drawing of video;
S1023 obtains the coupling figure from database;
S1024 perhaps carries out graphic retrieve in the information matches map-area with the information matches zone of the sectional drawing that matees figure substitution video, obtains matching probability;
S1025, repeating step S1024 obtains the matching probability that each matees figure;
S1026 is according to definite television channel or the television programme title of being play of the matching probability result of graphic retrieve acquisition.
The method of obtaining the television image sectional drawing has multiple, for example passes to third party device or software systems again by the decoded broadcasting pictures of the intercepting of television set own.Another kind method is directly to obtain the TV signal that television set is play by third party device or software systems, and the picture of inscribing during with a certain in the formed a series of continuous pictures of TV signal carries out intercepting.
After obtaining the television image sectional drawing, can execution in step S1022, confirm the information matches zone in the sectional drawing of video, perhaps intercepting message coupling map-area from the sectional drawing of video.That is to say, can be directly from the sectional drawing of video the selected part zone carry out follow-up graphic searching, also can be from the sectional drawing of video intercepting part picture as the information matches map-area as follow-up graphic searching.
In different countries or area, perhaps different TV stations all might be placed on station symbol any position of picture.Inventor of the present invention has investigated 67 television channels of China's Mainland and 133 television channels overseas.Through investigation, the inventor finds have 66 television channels that station symbol is arranged in 1/5 zone, television image top in the television channel of China's Mainland, and the station symbol that a local TV channel only arranged is outside this zone; And in the TV station overseas, having 130 television channels that station symbol is arranged in 1/5 zone, television image top, the station symbol that 3 television channels are only arranged is outside this zone.From investigation result, no matter be domestic television channel or television channel overseas, there is at least 97.7% television channel that station symbol is arranged in 1/5 zone, television image top.Through above-mentioned investigation, inventor of the present invention finds, TV station's station symbol matching area is set in 1/5 zone, television image top can realizes the object of the invention.But in order to increase reliability of the present invention, the inventor finds through overtesting, and is as shown in Figure 2, TV station's station symbol matching area is set in 1/4 zone at top of television image sectional drawing, can obtain well to search for effect.
And then execution in step S1023, obtain the coupling figure from database.Here said coupling figure comprises the station symbol figure of TV station, or the peculiar pattern identification of different TV programme.The station symbol figure of these TV stations or the pattern identification of TV programme can be pre-stored in the database, because popularizing of network obtained the standard television platform station symbol figure of each TV station or the test pattern sign of TV programme and be very easy to.Can be in station symbol figure or pattern identification shape input database with these standards, in needs, transfer the station symbol figure or the pattern identification of standard from database.
Then execution in step S1024 perhaps carries out graphic retrieve in the information matches map-area with the information matches zone of the sectional drawing that matees figure substitution video, obtains matching probability.That is to say; The coupling figure of the standard that database is preserved carries out match search with the image of information matches zone or information matches map-area, in order to find out the coupling figure whether the information matches zone perhaps exists the standard of preserving in the database in the information matches map-area.The method of carrying out this graphic retrieve has a lot; The first is utilized the graphic retrieve algorithm; For example leaf will is big equals mentioned specific algorithm in " a kind of improved image retrieval algorithm based on color histogram " that 2009 the 5th phases of University Of Jishou's journal (natural science edition) deliver; Similar algorithms has a lot, and its difference is accuracy and the efficient calculated.And present disclosed image retrieval algorithm maybe be perfect not enough, but the instrument of some unexposed algorithms that provided on the Internet but can reach good effect.For example, can utilize the business graphics gopher api interface that is provided on the http://www.tineye.com/commercial_api website to realize retrieval to the coupling figure.
The probability data that the coupling figure that can obtain standard with these algorithms or instrument institute is perhaps mated in the information matches map-area in the information matches zone.Inventor of the present invention finds through overtesting; This certain applications of pattern identification coupling for station symbol figure or TV programme; Do not need very high matching degree and can judge the station symbol figure of the standard that existence is preset in information matches zone or the information matches map-area or the standard graphics sign of TV programme; And only be higher than at 60% o'clock at the probability that matees, just can judge the station symbol figure or the pattern identification that there are preset standard in information matches zone or the information matches map-area.The complexity that this greatly reduces matching algorithm has reduced computing time, and has widened available station symbol matching algorithm.Therefore, the probability results that obtains according to graphic retrieve confirms that channel that TV is play or TV programme are calibrated really will definitely be to be set at probability greater than 60%.
The coupling figure that obtains in the database can be the pattern identification of some station symbol figures or TV programme, also can be part or all of station symbol figure or pattern identification.When needs confirm that whether in progress television channel is certain television channel of confirming, can be only extract specific station symbol figure in the database and mate.And when needing to confirm whether in progress television channel is the television channel of certain classification, can be from a plurality of station symbol figures of extraction respective classes in the database.Certainly, also can from database, extract all station symbol figures and carry out graphic retrieve, to confirm that which television channel in progress television channel specifically is.Also can carry out graphic retrieve with a plurality of TV programme pattern identifications, to confirm what in progress TV programme are with similar method.
Carry out the graphic retrieve of a plurality of coupling figures if desired, then can execution in step S1025, i.e. repeating step S1024 obtains the matching probability of each coupling station symbol.In this case, the probability results that obtains according to graphic retrieve confirms that channel that TV is play or TV programme are calibrated really will definitely be to be set at the highest and probability of probability greater than 60%.
Last execution in step S1026 is according to definite television channel or the television programme title of being play of the matching probability result of graphic retrieve acquisition.This step; Even behind the pattern identification of the station symbol figure of the TV station of default standard or TV programme, confirm in progress television channel of television set or television programme title in the database of having confirmed to exist in information matches zone or the information matches map-area according to the station symbol figure in the database and the mapping relations of concrete television channel information or the mapping relations of pattern identification and concrete television programme title.
In step S102, can also obtain the programme content of being play.For example, in the prior art, the variation of volume and/or frequency confirms to occur the content of scoring etc. in the time of can be through football match.These methods are known by those skilled in the art, repeat no more at this.
Next, execution in step S103 confirms pushed information according to the information of video again.As shown in Figure 3, this step specifically can comprise:
S1031 extracts keyword from the information of video;
S1032, from database retrieval and keyword information matching, perhaps retrieval and keyword information matching from the Internet;
S1033 confirms as pushed information with result for retrieval.
Television channel or the programm name play or even concrete information such as programme content from step S102, can have been obtained.Therefore, when execution in step S1031, can from these information, obtain the keyword of later retrieval.
After obtaining keyword, can execution in step S1032, from database retrieval and keyword information matching, perhaps retrieval and keyword information matching from the Internet.For example, can search out list of television programmes, literal or video ads from database or in the Internet through these keywords, comprise instant messages such as MSN or QQ and/or from the information of BBS or webpage.
Execution in step S1033 confirms as pushed information with result for retrieval then.Because these information that obtained among the step S1032 all are the information relevant with in progress video, so these information are to select relevant information with user's video.Active push relevant information through such has further realized the interaction of user and broadcast, and outstanding user experience is provided.
Last execution in step S104 is presented at pushed information in second viewing area of television set or display.As shown in Figure 4, second viewing area here can be formed the whole viewing area of said television set or display jointly with first viewing area of aforementioned playout video.Now a large amount of panel TVs that use of institute are displaying ratios of 16: 9 of employing, and when playing the video of original 4: 3 ratios, can have a white space.This white space of employing as shown in Figure 4 shows pushed information, can not impact original video displaying.Certainly, also can be as shown in Figure 5, second viewing area is the part of first viewing area, is about to pushed information and is superimposed upon on the video of former broadcast, and then outstanding pushed information.Perhaps as shown in Figure 6, second viewing area overlaps with first viewing area.
Through above-mentioned steps, can confirm the interested pushed information of user according to the programme content of being play in television set or zone of display, and with pushed information be presented at before the TV or another zone of display in.The user can be in a display frame not only watch programs but also view and the play content relevant information.
