Embodiment
In view of this, the object of the present invention is to provide a kind of video information adding method and device, video information indication method and device, can realize the dynamic demonstration of video information, strengthen user's experience.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
In the embodiment of the present invention, by Internet video is carried out to information annotate, on server, preserve and the corresponding video annotation stream of video.When starting video, load the video annotation stream corresponding with this video.When user is watching in video process, in the time of need to understanding the relevant information of some object occurring in video, only pointing device need be hovered in the region that described object is corresponding, can on described video pictures, annotation information corresponding to this object be shown to user.When user does not need to check this annotation information, only need mobile described pointing device to leave the region that described object is corresponding, can continue to watch video.Thus, can realize the dynamic demonstration of video information according to user's demand, strengthen user and experience.
Referring to Fig. 1, the video information adding method that the embodiment of the present invention provides comprises the following steps:
Step S101: choose time started and the end time of carrying out information annotate, choose a frame picture between described time started and end time.
When need to while carrying out information annotate, first choosing time started and the end time of this information annotate in section sometime to a certain object of video file.Generally speaking, carrying out in the time period of information annotate, this needs appearing at all the time on this video liking of information annotate.Therefore, described time started and end time just can be understood as: the time that needs the time that the object of annotation occurs on video and occur continuously disappearing from video after a period of time.For example, when a certain role in video carries out information annotate, first to determine the time period that need to annotate this role.Generally, only have while there is this role on video, just need to provide the information relevant to this role to user, therefore, can set and need to be the time period that occurs this role on video to the time period of this role's annotation.Suppose, in video playback to 7, in the times of minutes 20 seconds, occur this role, until be played to 9 minutes 30 seconds this role's message, the time started of setting this role's information annotate is " 00:07:20 ", and the end time is " 00:09:30 ".
Video is comprised of a large amount of and continuous frame of video, and a frame is exactly a static picture, and continuous frame of video forms dynamic video image.Between described time started and end time, choose a frame picture, be and choose a frame of video.Due between described time started and end time, need appearing at all the time on video liking of annotation, so confirmable, for the arbitrary frame between time started and end time, all there is the object that need to carry out information annotate.Therefore, between described time started and end time, choose a frame picture, be and choose a frame in this time and there is the picture that need to carry out the object of information annotate.
It should be noted that, for the present invention, can between described time started and end time, choose arbitrarily a frame picture.
Step S102: on described picture, select to add the hot-zone of annotation information, obtain the range information of this hot-zone.
It should be noted that, the size of the range information of described the hot-zone position on described picture and this hot-zone by this hot-zone determines.
In the method for the invention, described hot-zone can by pre-configured pointing device (as mouse, control lever, induction pen etc.) directly as described in select on the picture chosen.
Be specially, receive the click information of described pointing device, determine that described pointing device clicks corresponding coordinate figure at every turn.It should be noted that, described coordinate figure is the position on described video pictures.In conjunction with described pointing device, repeatedly click the coordinate figure obtaining respectively, obtain the range information of described hot-zone.Preferably, described hot-zone is generally rectangle.Certainly, in actual applications, described hot-zone can be arbitrary collection shape, as circle etc.
The rectangle of take describes as example, suppose that the coordinate that receives successively the twice click correspondence of pointing device on described picture is respectively P1 and P2, and P2 is positioned at the lower right of P1, and (abscissa of P2 is greater than the abscissa of P1, the ordinate of P2 is less than the ordinate of P1), can determine that the scope of described hot-zone is: take P1 as left upper apex, the rectangle of P2 as summit, bottom right of take.According to the symmetry characteristic of rectangle, be easy to obtain the coordinate figure on other two summits, the positional information of described hot-zone is the coordinate figure on four summits of this rectangle.
When having selected behind hot-zone, can obtain accordingly the positional information of this hot-zone on described picture.Take rectangle hot-zone describes as example, the coordinate of four summits that the positional information of described hot-zone is this hot-zone on described video pictures.For the selection of hot-zone, be generally to take that need to carry out the object of information annotate be foundation.For example, a certain role in video is carried out to information annotate, annotation information corresponding to this role should be added in the scope that this role occurs on this video.
Generally, according on the current described picture of choosing, the space size that this object occupies is selected the hot-zone of corresponding size.
In step S101, can between described time started and end time, choose arbitrarily a frame picture.Preferably, in order to facilitate the selection of hot-zone, when choosing picture, can select to need the object of annotation to show more clearly picture, or show the comparatively single picture of object.
For object, show that more clearly picture refers to: for example, when needs annotate a certain role, can select more clearly picture of this role front.Conversely, avoid selection to need fuzzyyer, the difficult picture of recognizing of object annotating as far as possible.For example, the picture of the role who annotates for needs in far position, the scope that this role occupies is very little, and the scope of corresponding selection hot-zone is also very little.So when take this picture as according to having chosen after the scope of hot-zone, for other frames in this time period, be difficult to guarantee that this object is still within the scope in this hot-zone.Again for example, for the object of needs annotations, be in high-speed motion or the picture of the scene of fighting, now may be difficult to this role's position to position, and then be difficult to determine the scope of hot-zone.
For showing that the comparatively single picture of object refers to: for example, the least possible picture of role comprising.Conversely, avoid the picture that role is numerous as far as possible, make to be difficult to realize the location to the object of needs annotation.For example, for the picture that shows a soldier of entire team, needing the object of annotation is in this group of soldier, is now difficult to realize the location to object.
In the present invention, the information annotate that this object is carried out not merely for a certain frame picture, is all to add this annotation information to all frames that comprise in described time started and time period corresponding to end time.Therefore, preferably, when selecting described hot-zone, can not only consider the space size that this object occupies on the current described picture of choosing, also need the size in conjunction with the space that in this time period, this object occupies on video, the comprehensive approximate range of determining that this object occurs within this time period on this video, as hot-zone.
Based on this, further, the method for the invention also comprises: in conjunction with all frame pictures between described time started and end time, the scope of described hot-zone is revised.
For example, in a frame picture of choosing, be only shown as the positive face that needs the object of information annotate at step S101, now according to this picture, the scope that can choose hot-zone is larger, even the size of video display frame really.But, for other frame pictures between described time started and end time, may not the full screen display of this object entirely, it is less even that possible this object only occupies half of video pictures.Now, if the scope setting of hot-zone is larger, when possible pointing device hovers on other roles, also show the annotation information that this object is corresponding, occur showing mistake.Again for example, suppose that the hot-zone scope of choosing according to a certain frame picture is too small, probably for other frame pictures, the scope that the object that need to annotate has departed from this hot-zone completely, while making user's pointing device hover on this object, cannot correctly show annotation information.For avoiding above-mentioned situation, now just need to, according to other frame pictures between described time started and end time, the scope of described hot-zone be revised.
Step S103: on described hot-zone, editor's annotation information.
On described hot-zone, edit the annotation information corresponding with the object that need to carry out information annotate.Concrete, described annotation information can be for the associated address of the information text that stores on text, hyperlink or described server etc.
For example, take the video of TV play < < A Dream of Red Mansions > > is example.When user watches < < A Dream of Red Mansions > > video, be easy to forget wherein some role's title and the relation between this role and dominant role.Particularly for the < < A Dream of Red Mansions > > of the new edition newly starting broadcasting, the performer who plays the part of each role is all new performers, for user, be not very familiar, make thus user more difficult to distinguishing of role.Therefore, in method, can, on described hot-zone, this role's title, performer's title, performer's qualifications and record of service etc. be annotated described in the embodiment of the present invention.When this role occurs on video, user can obtain this role's relevant information as required in described hot-zone, makes the user can be easy and straightforward role is recognized, the viewing that has strengthened user is experienced.
Described annotation information can be directly text, such as directly the form with text message is added on described hot-zone by this role's title, actor information etc., when video playback, is directly shown to user.Described annotation information can also be hyperlink, for example the URL address of the website relevant with this role is added on described hot-zone, when video playback, described URL address is shown to user, when user need to obtain this role's information, only need to click described URL address, can directly be linked to corresponding webpage.
Further, storing information text on server, is added on the associated address of described information text on described hot-zone as annotation information in advance.For example, still take < < A Dream of Red Mansions > > describes as example.Because the character relation of < < A Dream of Red Mansions > > is quite complicated, not much that the user who is familiar with very much original work is difficult to completely clear relation between each personage therebetween.Therefore, can manufacture in advance each role of < < A Dream of Red Mansions > > and other roles' the corresponding table of relation, as information text corresponding to each role, be stored on described server respectively, when needs carry out information annotate to certain role, only the associated address (being the storage address of this information text on server) of information text corresponding to this role need be added on described hot-zone.Certain described associated address can exist with the form of hyperlink, and the associated address of the information text that for example Jia Lian is corresponding can show " Jia Lian " on hot-zone.When video playback, on described hot-zone, show " Jia Lian ", when user need to know the more information of Jia Lian, only need to click " Jia Lian " showing on hot-zone, can open the text message corresponding with Jia Lian, obtain the detailed introduction of Jia Lian.For example, Jia Lian: the son that merchant remits, the husband of Wang Xifeng etc.
Concrete, 2 and 3 be described in detail in the process of editing annotation information on described hot-zone by reference to the accompanying drawings.Wherein, accompanying drawing 2 and 3 is respectively video information interpolation picture exemplary plot and information editing's frame exemplary plot of the embodiment of the present invention.
As shown in Figure 2, the personage who occurs in this picture is the object that need to carry out information annotate, by selecting suitable hot-zone (being the face area of annotation object in figure) on this picture of pointing device, starts annotation information edit box.Described annotation information edit box as shown in Figure 3, is write the annotation information relevant to this object in described annotation information edit box.Edit complete click and " determine " button, described annotation information will show on hot-zone.
In conjunction with Fig. 3, this annotation information can be text message, and text information can be inputted in " description " hurdle shown in Fig. 3, and the text message of writing at annotation information edit box will directly be presented on hot-zone.Preferably, can on hot-zone, show whole text messages.But in actual applications, consider that video pictures size is limited, when the content of text message is many, probably cannot in hot-zone, show completely, now, can only on hot-zone, show the partial content of text message, other guide is hidden, and set corresponding button for showing hiding content, as shown in " > > in detail " in Fig. 2.When user need to check whole text messages, only need button click " > > in detail ", can show whole text messages.
This annotation information can be also hyperlinked information, and this hyperlinked information is inputted in " http: // " hurdle of " role " and its correspondence in the drawings.Wherein " role " is the descriptor that is shown to user's hyperlink in hot-zone, and " http: // " be the URL of this hyperlinked information; By described annotation information edit box, the descriptor of hyperlink (as " the role ") URL corresponding with it (as " http: // ") associated.The hyperlinked information of writing at annotation information edit box, the descriptor of this hyperlink can be presented to hot-zone represents to user, as shown in Figure 2, when user's click is presented at the descriptor of the hyperlink on hot-zone, automatically user is redirected to the webpage of the corresponding URL appointment of this hyperlink.Preferably, can also on described hot-zone, show annotation information time frame, for time started and the end time that shows that described annotation information is corresponding, as shown in " 00:04:24 to 00:06:24 " in Fig. 2.
Further, can revise time started corresponding to described annotation information and end time by described annotation information time frame.
Step S104: corresponding time started and the end time of range information, described annotation information of hot-zone corresponding to described annotation information, described annotation information saved as to video annotation stream, be stored on server.
Set up time started corresponding to range information, the described annotation information of hot-zone corresponding to described annotation information, described annotation information and the incidence relation between the end time, and this incidence relation is kept in described video annotation stream.
Wherein, described video annotation stream is preserved with byte form.
Described hot-zone has been added after annotation information, and positional information, corresponding time started and annotation information corresponding to end time and this hot-zone that described hot-zone is corresponding are saved to server.Information corresponding to this hot-zone can be preserved with byte form, is called video annotation stream.
Described video annotation stream is corresponding one by one with video.Concrete, can add sign for described video annotation stream, the sign of described video annotation stream is corresponding one by one with video ID.
The video information adding method that the embodiment of the present invention provides, by sometime section in all frame of video in, choose a frame picture, on described picture, select to add the hot-zone of annotation information, on described hot-zone, edit the annotation information corresponding with this video, corresponding time started and the end time of range information, described annotation information of hot-zone corresponding to described annotation information, described annotation information saved as to video annotation stream simultaneously, be stored on server, can realize thus the corresponding relation of video and video annotation stream.When starting this video, load the video annotation stream that this video is corresponding.When video playback arrives a certain moment, according to user's demand, show the annotation information corresponding to relevant hot-zone in this moment frame of video, be shown to user, strengthen user and experience.
In the embodiment of the present invention, also provide a kind of video information indication method.Referring to Fig. 4, the video information indication method that the embodiment of the present invention one provides comprises the following steps:
Step S201: start video, load the video annotation stream that this video is corresponding.
In described video annotation stream, preserve corresponding time started and the end time of range information, this annotation information of hot-zone corresponding to all annotation information that this video is corresponding and this annotation information.
Described video annotation stream is kept on server, is byte form text.Described video annotation stream has sign, and the sign of described video annotation stream is corresponding one by one with video ID, corresponding one by one with video to guarantee described video annotation stream.
When receiving user and start the order of video, video described in startup of server, then the ID by described video finds the video annotation corresponding with this video and flows, and loads described video annotation stream.
In described video annotation stream, preserve corresponding time started and the end time of range information, this annotation information of hot-zone corresponding to all annotation information that this video is corresponding and this annotation information.
It should be noted that, for a video, its corresponding annotation information may have a lot.For example, for the annotation information of different role and for the annotation information of the different time for competiton sections of same role.Different annotation information, the positional information of the hot-zone that it is corresponding and time started and end time are incomplete same.For example, may be for role A and role B, possible its time for competiton section is identical, still, the position that role A and role B occur on video pictures must be different, therefore, to role A and role B, respectively position, hot-zone of corresponding annotation information is not identical for it.Or, for role A, the main region of its appearance in very first time section and the main region occurring in the second time period, may be identical may be also not identical, therefore, for role A, its hot-zone positional information, time started and end time in the annotation information of very first time section correspondence are also different from hot-zone positional information, time started and the end time in annotation information corresponding to its second time period.
Step S202: detect in real time pointing device, obtain annotation information corresponding to pointing device position described in current time, and show.
Concrete, described pointing device is pre-configured for triggering the equipment of video commands, such as external equipments such as mouses.For external equipments such as mouses, on computer screen, have corresponding cursor and show, the cursor demonstration that for example mouse is corresponding is generally arrow.The positional information of described pointing device is cursor that this pointing device the is corresponding positional information on computer screen.
When user watches video, when user need to check a certain role's who occurs in current in progress video information, mobile described pointing device, makes described pointing device place or hover on this role.Now, detect in real time described pointing device and obtain this pointing device position, by searching the video annotation being kept on server, flow, obtain the annotation information corresponding with this pointing device position of current time, be shown to user.
With reference to Fig. 5, it is the flow chart of video information indication method described in the embodiment of the present invention two.In embodiment bis-, elaborated described in step S202 and to have detected in real time described pointing device, obtained the detailed process of the positional information of pointing device described in current time.
As shown in Figure 5, described in embodiment bis-, video information indication method specifically comprises:
Step S301: start video, load the video annotation stream that this video is corresponding.
Step S302: detect in real time described pointing device, obtain the positional information of the cursor that pointing device is corresponding described in current time;
Step S303: search in described video annotation stream whether have the annotation information that current time is corresponding, if existed, enter step S304; Otherwise, enter step S306;
Concrete, the annotation information that described current time is corresponding refers to: the time started is less than or equal to the annotation information that described current time and end time are more than or equal to described current time.
Search described video annotation stream, each annotation information of preserving in described video annotation stream is judged respectively, determine whether to exist its time started to be less than or equal to the annotation information that current time and end time are more than or equal to current time.If existed, the annotation information that meets above-mentioned condition is the annotation information that current time is corresponding.
Step S304: search in the annotation information that described current time is corresponding, whether exist the hot-zone scope of annotation information to comprise the cursor position that described pointing device is corresponding, if existed, be annotation information corresponding to pointing device position described in current time, enter step S305; Otherwise, enter step S306;
Step S305: show annotation layer in the video of current broadcasting, show annotation information corresponding to described pointing device position on described annotation layer;
Wherein, position and the size of described annotation layer on described video determined by hot-zone scope corresponding to described annotation information.
Described annotation layer is for covering the translucent mask of one deck on specific regional area on described video pictures.Described annotation layer may be displayed on described video pictures and represents to user, and the configuration information of the hot-zone that the form that described annotation layer represents is corresponding with this annotation information is identical.
In order not affect user's viewing effect, the region contour of described mask for indistinctly highlighting can be set, in this regional extent, show this annotation information.When described pointing device is clicked hyperlink corresponding in this annotation information, user is redirected to webpage corresponding to this hyperlink.Further, can described annotation information be set to completely transparently, only within the scope of hot-zone corresponding to this annotation information, show and to avoid blocking video pictures, affect the content of annotation information user and watch.
Preferably, in the embodiment of the present invention, while showing annotation information, be only on current video picture, to appear annotation layer in one's mind, can not follow prompt tone etc., to avoid affecting user, watch video.
With reference to Fig. 6, be the annotation layer exemplary plot of the embodiment of the present invention.As shown in Figure 6, when annotation information corresponding to pointing device position described in finding current time, can in the specific regional area of current video picture, (being hot-zone) show annotation layer, on this annotation layer, show annotation information, this annotation information can comprise role's title (as " Lin Manyi " in Fig. 6), the title (as " Han Xue " in Fig. 5) of playing the part of this role's performer, the corresponding details of role (as in Fig. 6 " without boyfriend three without beauty ").Wherein, " Lin Manyi " and " Han Xue " is hyperlinked information, when clicking " Lin Manyi ", automatically user is redirected to the webpage of " Lin Manyi " corresponding URL appointment; " without boyfriend three without beauty " be text message; " > > in detail ", for hiding whole text messages, when clicking " > > in detail ", will show whole text messages to user.
