Fig. 1 shows the interactive video play system 100 according to the embodiment of the present disclosure.System 100 includes remote service
Device 104 and the user terminal communicated with the remote server 104 by the various networks such as internet or mobile Internet.
User terminal includes processor 101, input unit 102 and display 103.Processor 101 can be any general or special purpose
Central processing unit or controller etc..Input unit 102 can be mouse, can also be integrated and shape with display 103
At touch screen.User can watch video file by user terminal, which can both be stored in local, can also deposit
Storage is transmitted on remote server 104 and by network.
Fig. 2 is the flow chart according to the interactive video playback method of the embodiment of the present disclosure.The flow chart of this method is wrapping
It includes and is executed in the system of user terminal and remote service net 104.Wherein in step s 201, in the multiframe figure of the video played
Interaction area defined in reference frame as in and the square judgement area for surrounding interaction area.The selection of reference frame can be according to
Every 10 frame, 30 frames, 60 frames are chosen primary fixed intervals and are chosen, and can also include one to the layout of video by advance
Multiple frames being pre-selected of series.Reference frame preferably includes I frames (intracoded frame) or P frames (forward-predictive-coded frames), can
To be chosen according to when there is interaction content in video.The article shown in the videos such as film, live streaming be possible to
Various angles occur with rotating, and interaction area is then to surround the contour line of article, therefore the contour line is generally all constituted not
The edge of the shape and fluctuating of rule.For example, the contour line 111 of interaction area may be according to article as shown in being realized in Fig. 1
Difference and in size, rotation and different in shape.To irregular shape carry out image recognition implement it is complex, and
It it may also be desirable to transmit the interaction area information of various articles between user terminal and remote server 104.In order to reduce
The treating capacity needed, the square judgement area of the defined herein contour line 111 for surrounding interaction area.Such as it is shown in dotted lines in Figure 1
Interaction area is included by square judgement area 110.Since user is carried out with mobile terminals such as mobile phones in many cases
Video and shopping are watched, the article actual size shown on mobile phone screen also will be smaller because of screen size, generally about
Equal to the size of user's finger tip.In the case, point-device judgement area is not needed to, and is available with square judgement
Play the role of simple flow and be easy to click in area 110.
The interactive areas that pre-stored commodity provider defines in video can be read by the processor 101 of user terminal
Domain simultaneously defines square judgement area, can also be defined by artificial means after interaction area while transmitting the content of video
By interaction area information, such as coordinate value and timeline information, user terminal is transmitted to so that processor 101 is when playing video
Additional interaction area and square judgement area.The interaction area defined in each image and square judgement area's workload are larger,
In particular by the occasion of Manual definition, therefore in step S202, area is judged according to square in the frame after reference frame
In at least one macro block motion vector come move square judgement area.Judge that in area multiple macro blocks can be selected from square,
Each macro block is for example including corresponding 8*8 totally 64 pixels (sample) or the 16*16 brightness of totally 256 pixels (sample) and colorations
Etc. contents, opposite variation of the image in interframe may determine that by movement of the macro block between multiframe.For example, can by one or
Mobile the constituted motion vector of multiple macro blocks directly acts on square judgement area, to the case where only defining reference frame
The interaction area defined in remaining frame and square judge area automatically down.It itself is including the video compression format of motion vector
In, it can also directly invoke the motion vector that it is included and not have to separately calculate.
It is selected within square judgement area in response to user in step S203, such as mouse is clicked, finger touches
Deng, and show and the most similar static images in square judgement area and reception and display and the most similar static images
Associated URL information.Defined square judgement area and the interaction area that is included will be used for
Static images in being stored in resources bank are matched, which can be in user terminal or remote server 104 any one it
Upper progress.Video can be closed when playing with multiple training sets in resources bank according to its classification and summary info
Connection, and static map the most approximate is found by the similarity mode of picture in the square judgement area clicked and training set
Piece.And every width static images can correspond to a kind of commodity, and be stored with corresponding to it on user terminal or remote server 104
Uniform resource locator (URL) information and the auxiliary informations such as pricing information, type information, favor information, express delivery information.This
A little information are preferably stored on remote server 104, and can be modified by commodity provider, and are sent to by network
User terminal.After finding static images the most approximate and finding corresponding URL information, it can sentence in the square clicked
Determine to show above- mentioned information within area.Can also with hyperlink form by URL it is associated with static images and user click it is quiet
The URL is linked to when state picture.Static images can judge Qu Shangxian in such a way that partially transparent and edge is highlighted in square
Show, and substantially overlapped with interaction area, this helps that user is allowed to obtain more accurately feeding back interaction.
Feature vector mode can be used first by finding static images the most approximate, judge area by searching for square
The highest static images of the degree of correlation of the feature vector of the picture element matrix constituted carry out.The degree of correlation for example can be related
Coefficient, vector distance etc..Such as square judgement area itself may be constructed picture element matrix, or can judge area from the square
Each position macro block in choose a series of pixels to constitute picture element matrix.It can be looked by a variety of existing computerized algorithms
The feature vector of the matrix is looked for, and is compared with the feature vector of the individual features matrix of each static images.It finds the most
Secondly approximate static images can use the machine learning mode such as convolutional neural networks, square judgement area's content is defeated
Enter the grader after the static images training using a variety of commodity to be identified.Finally, static map the most approximate is found
Piece can also be matched using the feature on the images such as Color Range, COLOR COMPOSITION THROUGH DISTRIBUTION, limb recognition.Such as it can first search
Color gamut and the approximate region of picture element matrix, then further limited by the comparison of edge finding and each color channel values
Seeking scope.In addition, can also be completed using above method to the calculating of the motion vector of macro block.
If user has carried out the selected action other than square judgement area, as in step S204 to remote server
104 send feedback information, which includes the reproduction time information of video when position occurs and occurring of selected action.
Remote server 104 can extract the corresponding image in the region clicked of user by reproduction time information with position occurs, and
The image is supplied to commodity provider for learning user to the interested information of which kind of article.If defined interaction
Extensive stock corresponding to region does not include the interested content of user, then it is emerging user's sense can be added according to the feedback information
The commodity of interest, this is highly useful for commodity provider.Feedback information can also include the connection such as user name, the mobile phone of user
It is mode and operation history etc., can is in this way that user realizes personalized interaction content according to feedback information, be every use
Family targetedly provides the commodity interested to it, and the long-term unselected type of merchandise can delete its interaction area.
Feedback information can also include judging the selected action carried out within except area in square at user's current time
The ratio between number, if the ratio is significantly greater than 1, it may be said that bright user lacks interest for current push, and should mutually cope with push
Interaction area modify.
In step S205, only it is less than at a distance from square judgement area edge pixel in the generation position that user selectes pre-
First when determining offset, the movement in square judgement area is modified according to feedback information.Edge pixel, which is criticized, rectangular to be sentenced
Determine the pixel of area edge position.If the position that user clicks judges in square except area, but still sentences from square
The distance for determining area edge pixel is less than a predetermined offset, then may be at this time that user has clicked article, but because being square
The position in judgement area occurs in deviation leads to judge that area fails article being entirely included in.The offset is preferably square judgement
The half of area's catercorner length detects user's click location apart from nearest pros in user terminal or remote server 104
When shape judges that the distance in area is less than the offset, the square judgement area nearest particular more than one click positional distance away from
It, should be one additional to square judgement area in frame later according to the generation position in feedback information when from less than the offset
Motion vector, the neighbouring motion vector are superimposed with according to the obtained motion vector of macro block movement so that it is moved to preferably
The position overlapped with commodity.This adjustment can by machine or it is artificial carry out, and adjust after result can be stored for
Broadcasting use.
If position occurs for selected action within the square judgement area of more than two interaction areas, shown
Static images and URL information are according to two diagonal vertex positions in two or more square judgement area
Average value and the immediate square in generation position of selected action judge area to determine.When commodity are more intensive, portion
The square judgement area of multiple interaction areas is likely to occur overlapping in framing, position when user clicks overlapping region and which just
The average value of two diagonal vertex positions in rectangular judgement area is closest, decides that user is selected and judges for the square
Area.A variety of static images and URL information can also be provided at selected overlapping region simultaneously so as to user therefrom
It is selected.The position in square judgement area and situation of movement can also be sent to remote server 104 to synchronize.
Those skilled in the art are readily apparent that when checking shown drawing and description is dependent on concept and principle of the present invention
The various other devices and/or method of embodiment are included within the scope of disclosure of the invention, and are not limited to above-mentioned be expressly recited
