Before step 101, the television terminal side need to obtain video interception, and concrete acquisition pattern has multiple, such as real-time acquisition video interception.Perhaps, the continuous sectional drawing of the time interval according to default obtains a plurality of video interception.The default time interval is 0.1 second level, 1 second level etc.The video interception quantity that obtains continuously is N, and the better span of N is 100～200.
Better, the television terminal side does not need to send video interception to server when channel unread changes, and after each channel change, sends video interception to server, opens video interception such as continuous transmission N.Can reduce like this quantity that sends video interception.
It is multiple that the television terminal side judges that specifically mode that whether channel changes has, and analyzes such as the color to the station symbol zone of video interception, judges according to the variation of color whether channel changes, and wherein the station symbol zone comprises four angular zones in the video interception.
The television terminal side judges that specifically the process whether channel change is as follows:
Because station symbol its pixel value in a plurality of video interception all is constant, obtain the pixel characteristic that K opens station symbol neighboring area and station symbol in the sectional drawing, and utilize this pixel characteristic as training sample training pattern to be trained, training pattern can specifically adopt vector machine (SVM) model.Wherein, pixel characteristic can adopt color histogram to represent.
Obtained after the training pattern, the television terminal side just can utilize this training pattern to judge whether channel changes.Namely, the video interception that newly obtains is input in the training pattern, the pixel characteristic of video interception and the characteristic set in the training pattern are mated, if the similarity of coupling surpasses default threshold value, then output valve is true, the pixel value relation that is station symbol and peripheral region does not change, and determines that then channel unread changes, otherwise determines that channel changes.
Introduce the process of television terminal side channel-identification below by a specific embodiment.

Step 302: the station symbol in the video interception is analyzed, determined the station symbol in the video interception.
Step 303: according to the corresponding relation of station symbol and channel information, determine channel information corresponding to station symbol that analyzes.
Step 304: the channel information of determining is sent to television terminal.
Wherein, server side comprises a lot of aspects to the analysis of the station symbol in the video interception, analyzes such as the corner areas to video interception, and corner areas is the zone that the station symbol most probable occurs.This part zone is analyzed, can be improved the efficient of analysis, and reduce the interference of extraneous areas to analyzing, improve the accuracy of analyzing.
And, may exist a channel to relay the situation of the program of another channel, so just a plurality of station symbols may appear in a video interception, a plurality of station symbols possibilities are overlapping may be not overlapping, then relate to the analysis to a plurality of station symbols, determine to identify in a plurality of station symbols the main station symbol of current channel, namely identify the station symbol of the channel of broadcast program.
To the TV station symbol recognition in the various situations, all be based on training pattern and realize.The process of structure training pattern is as follows:
If N TV station arranged, each intercepting K of TV station is opened sectional drawing as training sample, get in addition the training sample that L opens figure conduct " without the station symbol " scene that does not comprise any Channel icons simultaneously.
Because the position of station symbol in video interception be substantially constant, therefore, the K of each channel to be opened figure superpose, capture element mean value can be determined the position of the station symbol of each channel basically.Centered by the center of each station symbol t, get a rectangular area R (t).
To N channel, train N+1 model (comprising without the station symbol model), suppose that training pattern is M (t), then for the corresponding model M of channel N (t) (t), to all N*K+L pictures, subgraph S (i) according to rectangular area R (t) intercepting picture corresponding to N (t) then extracts feature, and (svm) trains with SVMs.Shown in following function.
svm_model＝svm_train(featurelist，labellist)；
Labellist is the corresponding label of feature list (tabulation) (label) information, if this feature belongs to station symbol t, then label is 1, is 0 if not label then.Can train like this relevant with the station symbol model of N and 1 without station symbol scene Recognition model.
Can obtain training pattern by said method, just can analyze the station symbol in the video interception by this training pattern afterwards.Concrete mode is as follows:
For the video interception of an input, according to each model, extract feature, be input in the following anticipation function.
[Predict_label，probability]＝svm_predict(svm_model，feature)
Wherein, svm_model represents that the training pattern that adopts, feature represent the feature of extracting, and svm_predict represents the vector machine anticipation function.If function returns: predict_label==1, then expression is predicted as "current" model, if predict_label==0, then expression is not "current" model, probablility is fiducial probability.At last, get predict_label be 1 and the highest corresponding station symbol of model of fiducial probability be the station symbol of prediction.
For the situation that a plurality of station symbols superpose, a platform may have multiple station symbol, only need to mark the main station symbol that should be identified as under this scene the situation of correspondence also as training sample, carry out above-mentioned model training and get final product.
