Description

A kind of method that in video program play, is dynamically embedded into other media fragments
Technical field
The present invention relates to the video stream media application, especially relate to a kind of method that in the video program play picture, is dynamically embedded into other media fragments.
Background technology
Continuous increase along with the Internet bandwidth, video request program, direct seeding technique have obtained developing rapidly, the Internet video program is looked at by people's eyeball more and more, especially popularizing gradually of broadband internet, digital tv network, mobile phone 3G network, the video stream media industry will welcome a unprecedented opportunity to develop.Mobile Internet is a development trend from now in addition, and the problem of mobile Internet maximum is that bandwidth is little and fluctuation is big, even in the 3G epoch, the restriction of wireless bandwidth and fluctuation remain the key factor that will consider in the video playback.Compare with wired internet, the resource of wireless bandwidth is that cost limited and that use is higher, and the network service item of many new releases will obtain repayment, must make rational profit model.Video frequency program resource free on the present the Internet is more and more abundanter, provides service iff the charge that relies on video frequency program itself to the netizen, and the significant limitation and the market risk are arranged.Therefore with reference to the profit model of TV programme, for spectators provide free programme content, and by playing a certain amount of advertisement to spectators, the practice from advertising expense to the advertiser that collect ripe a kind of maturation be full of the pattern of looking.In the mobile Internet epoch, this by the profit mode that in video frequency program, breaks for commercialsy with long-term existence.But this practice also has many defectives: the one, in the playing programs process, break for commercialsy, concerning most of spectators, the advertisement of intercutting has been formed resistance psychology for a long time, and advertisement has become the resting machine meeting in the middle of the TV reception gradually, makes advertising results reduce; The 2nd, if the advertisement of intercutting is too much, will cause that spectators complain, the ban that limits the TV programme advertisement as the prime time of General Bureau of Radio, Film and Television's appearance has just illustrated this point; The 3rd, the mass advertising in the TV programme is that repetitive cycling is thrown in, and does not segment spectators, and the rate of precision of advertisement is very low, and effect is had a greatly reduced quality naturally.Owing to be subjected to these factor affecting, if the Internet video program is indiscriminately imitated the pattern of television advertising, possible effect is poorer than television advertising.Because on portable terminals such as mobile phone, watch video frequency program, the playing progress rate that the user fully can the control of video program, the user just can skip the web advertisement that intercuts easily.Therefore will solve a problem, allow the user freely watch video frequency program, and get a profit by network advertisement inter-broadcasting, the broadcast of the web advertisement simultaneously can not be watched by the normal video frequency program of interference user, and the user can not remove the broadcast of the web advertisement when watching video frequency program, this is an insoluble contradictory problems outwardly, at TV and wired internet video field, this problem long-term existence, good solutions of neither one all, but enter the mobile Internet epoch, this solution demand is more urgent.
Summary of the invention
Technical problem solved by the invention is to provide a kind of and is dynamically embedded into the method for other media fragments in current video program is play, and does not disturb the broadcast of current video program.But in the audio/video player system of forming by the video playing terminal of video server and displaying video information, video server sends video program information when playing on the video playing terminal, other media fragment content can be inserted in the in progress video frequency program, on video playing terminal, play, comprise the steps: with screen
(1) sets up a foreign medium clip file storehouse, this foreign medium clip file storehouse comprises a media fragment file at least, described media fragment is a plurality of classifications, can mark off a plurality of subclass under the classification, all classifications and subclass all have can other item name of phase region, each media fragment all has numbering, and this numbering is unique, can call any one media fragment by numbering;
(2) set up the video program data storehouse, at least comprise a video frequency program file in this video program data storehouse, has a timestamp in this video frequency program file at least, this timestamp is distributed in the broadcast process of video frequency program file, at each video frequency program file when playing continuously, by this timestamp, can in the video frequency program of playing, insert other foreign medium fragments;
(3) for each timestamp in the video frequency program distributes corresponding foreign medium fragment link, the timestamp in the video frequency program also is divided into identical classification sequence, system associates the timestamp classification in foreign medium fragment classification and the video frequency program automatically; Thisly be associated with the input that is beneficial to the sorter network advertisement that is implemented in the video frequency program, can come in ad content is related with video content, strengthen advertising effect.When being a ball match, can intercut the sports goods advertisement as the content of video playback.
(4) when video program play, when the process of broadcast program arrives a timestamp, the foreign medium segment contents of link is inserted in the video frequency program of current broadcast, the inserted mode here is one of following three kinds:
Mode one: suspend the video frequency program of current broadcast on video playing terminal, the video playing terminal full screen is play the foreign medium fragment of link; The manner is equivalent to traditional television advertising, and this mode has occupied user's video playing terminal screen by force to following advertisement, allows the user watch advertisement by the mode of forcing, and is the most serious to user's interference.
Mode two: on the screen of video playing terminal, mark off a new play area, in new play area, play the foreign medium fragment of link, and the video frequency program that does not interrupt current broadcast; In this mode, advertisement broadcast window of stack on the video playing terminal screen, be equivalent to the picture-in-picture in the TV, because mobile terminal screen is generally less, the advertisement broadcast window is unsuitable excessive, otherwise the obvious user of influence is watched video frequency program, cause that the user resists, can influence advertising results again but advertisement windows is too small, can be set to allow the user regulate, but the user can not close.
Mode three: the foreign medium segment contents of link is added in the video frequency program of current broadcast, and the video frequency program that does not interrupt current broadcast.Under this mode, advertisement directly is added on the video content picture,, watches the video frequency program influence minimum the user as the captions advertisement on the picture.
Consider that most of user has the psychology of resistance to the advertisement of intercutting in the video, optimize advertisement as far as possible and experience, alleviate interference the user.Therefore in the mode three of aforesaid step (4), the foreign medium fragment that is superposeed is the bright background of full impregnated, and its prospect is presented on the video frequency program picture of current broadcast in floating mode.After adopting transparent background, have only the prospect of advertisement picture to influence a part of video pictures, when product figure is arranged in the advertisement picture, have only the product profile to be presented on the video pictures, alleviated the video interference.
Above-mentioned video is disturbed and can further alleviate, and the prospect of the foreign medium fragment that is superposeed is translucent, and its transparency can be regulated between 0 to 100%.When product figure was arranged in the advertisement picture, the product image also was translucent, saw through the product image, also can watch video pictures.
Because the brightness of the picture of the video frequency program play is generally according to the content change of video pictures scene, darker as picture in the scene in evening, the sun is brighter down, if if this moment advertisement picture brightness and transparently do not adjust, will contrast excessive, the video frequency program of being play is caused interference.Therefore to further optimize technique scheme, the transparency of the prospect of the foreign medium fragment that is superposeed and brightness are regulated according to the current video frequency program picture brightness of playing automatically by video playing terminal, and it is linear with the video frequency program picture brightness, when the video frequency program picture brightness increases, transparency increases, otherwise transparency reduces, and the foreign medium fragment that keeps being superposeed not exclusively hides the video frequency program picture.This advertisement picture that will intercut is with the transparency and the brightness of the luminance dynamic adjustment self of video frequency program, and also the program picture combines together, has alleviated interference.
Above-mentioned foreign medium fragment is for can be divided into following type:
1, text subtile
Roll display on the video frequency program picture, its transparency 50%, general spectators' vision can be seen the video frequency program picture that captions cover clearly by captions, and the video frequency program picture does not influence the identification of captions yet simultaneously.The captions demonstration of also can glimmering, and on the video pictures of playing that is added to.
2, static images
The prospect of this picture can be fixed or roll display on the video frequency program picture, its transparency 50%, and general spectators' vision can be seen the video frequency program picture that picture covers clearly by this picture, and the video frequency program picture does not influence the identification of this picture yet simultaneously.
3, motion picture
The prospect of this motion picture can be fixed or roll display on the video frequency program picture, its transparency 50%, general spectators' vision can be seen the video frequency program picture that motion picture covers clearly by this motion picture, and the video frequency program picture does not influence the identification of this motion picture yet simultaneously.
4, video segment
This video pictures is fixing the demonstration on the video frequency program picture, its transparency 50%, and general spectators' vision can be seen the current video program picture that video pictures covers clearly by this video pictures, and the video frequency program picture does not influence the identification of this video pictures yet simultaneously.
After the foreign medium fragment of intercutting also can be above-mentioned four any two or more groups in all types of, to increase advertising results.
Further optimization to technique scheme is, described media fragment is inserted after video server downloads to this locality by video playing terminal again, after video server and video playing terminal are set up video and are connected, mutual by video playing terminal and video server, detect the bandwidth processing surplus on the video playing terminal in real time, and following mode is handled:
As connecting, but no video playing programs or video pictures suspend on the video playing terminal, the maximum code that video playing terminal is supported with current network bandwidth place immediately flows down carries the foreign medium clip file that is linked and is stored to this locality, if video playing terminal is recovered video playback in the downloading process, then reduce the code stream of downloading.
If the current network bandwidth fluctuates, or the increase of the video frequency program code stream of current broadcast, the code stream that the foreign medium fragment is downloaded then further reduced;
If the buffering phenomenon takes place in the video frequency program of current broadcast, then suspend the download of foreign medium fragment, when the rear video playback terminal has detected bandwidth gap later on, recover the download of foreign medium clip file, if the foreign medium clip file was not downloaded last time, then continuous the holding of breakpoint continues to download, and finishes up to download;
Above-mentioned foreign medium fragment is all downloaded on the backstage, does not influence the result of broadcast on video playing terminal foreground.
Because the broadband of wireless network is stable inadequately, sometimes fluctuation is bigger, after the broadband diminishes, if the code stream that video playing terminal received is too small, when being not enough to smooth playing, the video frequency program of current broadcast can cushion phenomenon, and this moment, video playing terminal began to play the foreign medium fragment that has downloaded to this locality, if buffering finishes, the broadcast that recovers video frequency program immediately.This will be avoided allowing in buffering course the user wait for, utilizes this time to play advertisement, allows the user have a rest, and advertisement is appreciated in the gap of rest.
Beneficial effect of the present invention is, uses the media fragment among the present invention to be dynamically embedded into technology, can make and optimize intercutting of the web advertisement, and the web advertisement and video frequency program are organically combined, and alleviates the annoyance level to video playback.

Understand and enforcement the present invention for the ease of those of ordinary skills, the present invention is described in further detail below in conjunction with reaching embodiment in conjunction with the accompanying drawings.
Along with the continuous increase of the network bandwidth and people continuous growth to network media demand, Internet video will become new network development focus, because spectators tend to reference to traditional tv the understanding of Internet video, and the new service item on the network generally all is from freely, and service provider generally places on profit the value-added service and the web advertisement.But Internet video is relative with traditional TV, and the user has higher selectivity and interactive, is difficult to force users and sees advertisement, therefore is necessary from technological means, alleviates the web advertisement is watched video frequency program to the user interference.The present invention is embedded into the web advertisement in the video program content of broadcast by technological means, and by classification and directed advertising, has alleviated the interference of the web advertisement to spectators effectively, and improved the effect of the web advertisement to greatest extent.
Here with the example that is developed as of video ads jettison system, embodiment of the present invention are described.
Step 1: set up a foreign medium clip file storehouse, promptly set up a web advertisement database.
Can use the SQL database system, one of database master meter can be a web advertisement table, comprise fields such as " advertisement numberings; ad title; adline; advertisement classification; ad content; advertisement state ", wherein field " adline " comprises " copy; display advertising; animated advertising; video ads ", field " advertisement classification " refers to the trade classification of advertisement, it is the determinant attribute of classified advertisement, as " electrical type; software class; clothes class " etc., can the little classification of nested multilayer under the big classification, the name of the standard of classification is formulated by the operator of the web advertisement.Field " ad content " is relevant with the advertisement classification, if " copy ", ad content only is to be made of text character, and modification can be with in literal.If the advertisement of other type, field " ad content " then is made up of literal and picture.
Step 2: set up a video program data storehouse and insert the time spot stamp.
This database is exactly the video frequency program resources bank, comprised video frequency program file to be played, for the web advertisement is broadcast in the video program content, need stab the definition time spot in the video pictures, this timestamp can be distributed automatically by system, it as a reproduction time length 100 minutes video frequency program, if evenly intercut 9 web advertisements, then will stab " 10; 20; 30 ... 90 " that are distributed in video program play the time spot minute locates, this timestamp also can be by manual allocation, can connect this moment with web advertisement classification, to stab the program place that is inserted into related content the time spot, to intercut if any the individual web advertisement about the Samsung mobile phone, can use the leading role of video frequency program in the picture of mobile phone and insert timestamp, the web advertisement if any individual BMW will intercut, and can open the leading role of video frequency program in the picture that BMW goes at express speed and insert timestamp, can strengthen the effect of the web advertisement like this.
Step 3: set up linking of video frequency program and the web advertisement
For each timestamp in the video frequency program distributes corresponding foreign medium fragment link, the timestamp in the video frequency program also is divided into identical classification sequence, system associates the timestamp classification in foreign medium fragment classification and the video frequency program automatically.This link will be in the ad production link of video frequency program be made specially, purpose be ad content and video program content are carried out related, to improve audient's precision of advertisement, as relay video at a ball match, sports goods advertisement that can related correspondence.
Step 4: insert the web advertisement during video program play.
The time spot of inserting in step 2 stabs and is used for the playing network advertisement, the web advertisement can embed or be added in the video pictures, watch video frequency program in order not influence the user, the web advertisement can be play on any one edge on four limits of video program play terminal screen, as the following roll display of screen.The method of inserting the web advertisement can have following several:
1, inserts at random
The process of video program play is every to reach a time spot when stabbing, web advertisement of random extraction inserts and plays from web advertisement storehouse, it is identical that system can specify each web advertisement to play frequency, and in a playback period, each web advertisement is all play once.
2, order is inserted
The process of video program play is every to reach a time spot when stabbing, from web advertisement storehouse, extract a web advertisement in order and insert broadcast, in a playback period, each web advertisement is all play once, and when played in order, the advertising results of forward more broadcast are just better, because the user is higher to emerging advertisement form attention rate, the advertisement that goes out has later on just formed certain fatigue, even the user is when only seeing the video frequency program of front, and the advertisement of back just not have the chance of broadcast.
3, classified advertisement is inserted
Advertisement segmentation pattern at random above-mentioned or played in order pattern basis, reach time spot when stabbing when the process of video program play is every, the classification of stabbing according to the time spot from web advertisement storehouse at random or the order web advertisement that extracts an identical category insert and play, it is identical that system can specify each web advertisement to play frequency, in a playback period, each web advertisement is all play once.
4, particular advertisement is inserted
It also is a kind of advertisement segmentation pattern at random above-mentioned or played in order pattern basis, stab in the time spot in advance and set up the particular network advertisement link, reach specific time spot when stabbing when the process of video program play is every, the link of stabbing according to the time spot is extracted the specified web advertisement of link and is inserted broadcast from web advertisement storehouse.
5, the condition trigger-type inserts
The trigger condition of an advertisement insertion is set in the audio/video player system, this trigger condition can be special sound or the image that occurs in special time or the video pictures, be that video frequency program is when live, a testing conditions is set, picture image and sound when detecting the program transmission by video server, in case detect qualified picture or sound, with regard to intercutting of trigger network advertisement.As the condition of a detection car is set, when video program play, system constantly detects picture, if detect the Rule of judgment (if any license plate number or wheel characteristics) that certain object that moves that occurs on the video pictures meets car, just insert the web advertisement of playing a relevant car automatically.
6, targeted ads inserts
The user is when the order video program, system extracts the user on-site IP address of surfing the Net automatically, therefrom analyze the area of user's online, when time spot of video program play process arrival stabbed, system inserted a targeted ads of throwing in towards this user location automatically in the video frequency program of current broadcast.Here need in system, set up an IP address ownership place database, bring in constant renewal in safeguard, guarantee that the IP address can accurately represent user's source place.The IP address that detects user's online of certain order video program as system is 202.96.133.xxx, system's retrieval IP address ownership place database, find this user from Shenzhen, just the web advertisement that inserting surface is thrown in to area, Shenzhen in the video frequency program that this user watches.
In addition, can make full use of the digitalized signature of network video advertisement, strengthen the experience effect of advertisement, allow spectators be easy to accept by following mode.
Mode one: suspend the video frequency program of current broadcast on video playing terminal, the video playing terminal full screen is play the foreign medium fragment of link; The manner is equivalent to traditional television advertising, and this mode has occupied user's video playing terminal screen by force to following advertisement, allows the user watch advertisement by the mode of forcing, and is the most serious to user's interference.Do not advise adopting the advertisement mode of this mode in practice.
Mode two: on the screen of video playing terminal, mark off a new play area, in new play area, play the foreign medium fragment of link, and the video frequency program that does not interrupt current broadcast; In this mode, advertisement broadcast window of stack on the video playing terminal screen, be equivalent to the picture-in-picture in the TV, because mobile terminal screen is generally less, the advertisement broadcast window is unsuitable excessive, otherwise the obvious user of influence is watched video frequency program, cause that the user resists, can influence advertising results again but advertisement windows is too small, can be set to allow the user regulate, but the user can not close.For small-screen mobile terminals such as mobile phones, realize that this advertisement acquires a certain degree of difficulty, advertisement windows can not be excessive, otherwise will a presumptuous guest usurps the role of the host, causes that spectators are discontented.Suggestion advertisement windows area is no more than 30% of terminal screen area, and in very little advertisement windows, in order to obtain surface effect preferably, the advertising segment image content is succinct, exquisite,
Mode three: the foreign medium segment contents of link is added in the video frequency program of current broadcast, and the video frequency program that does not interrupt current broadcast.Under this mode, advertisement directly is added on the video content picture,, watches the video frequency program influence minimum the user as the captions advertisement on the picture.But this mode also can mislead the user sometimes, as captions occur, and allowing spectators think by mistake is the descriptive information captions of video frequency program itself, after spectators know to be advertisement, will produce and be sick of psychology, therefore is necessary to remind or annotate AD tagged.
Consider that most of user has the psychology of resistance to the advertisement of intercutting in the video, optimize advertisement as far as possible and experience, alleviate interference the user.Therefore can further adopt technological means to alleviate above-mentioned commercial breaks, can pass through to adopt transparent advertisement picture pattern the influence that spectators watch video frequency program.
1, transparent background advertisement
The foreign medium fragment that is superposeed is the bright background of full impregnated, and its prospect is presented on the video frequency program picture of current broadcast in floating mode.After adopting transparent background, have only the prospect of advertisement picture to influence a part of video pictures, when product figure is arranged in the advertisement picture, have only the product profile to be presented on the video pictures, alleviated the video interference.
2, the translucent prospect advertisement under the transparent background
Above-mentioned video is disturbed and can further alleviate, and the prospect of the foreign medium fragment that is superposeed is translucent, and its transparency can be regulated between 0 to 100%.When product figure was arranged in the advertisement picture, the product image also was translucent, saw through the product image, also can watch video pictures.
3, the automatic adjusting of advertisement foreground to transparent degree and brightness
Because the brightness of the picture of the video frequency program play is generally according to the content change of video pictures scene, darker as picture in the scene in evening, the sun is brighter down, if if this moment advertisement picture brightness and transparently do not adjust, will contrast excessive, the video frequency program of being play is caused interference.Therefore to further optimize technique scheme, the transparency of the prospect of the foreign medium fragment that is superposeed and brightness are regulated according to the current video frequency program picture brightness of playing automatically by video playing terminal, and it is linear with the video frequency program picture brightness, when the video frequency program picture brightness increases, transparency increases, otherwise transparency reduces, and the foreign medium fragment that keeps being superposeed not exclusively hides the video frequency program picture.This advertisement picture that will intercut is with the transparency and the brightness of the luminance dynamic adjustment self of video frequency program, and also the program picture combines together, has alleviated interference.
Above-mentioned foreign medium fragment is for can be divided into following type:
1) text subtile
Roll display on the video frequency program picture, its transparency 50%, general spectators' vision can be seen the video frequency program picture that captions cover clearly by captions, and the video frequency program picture does not influence the identification of captions yet simultaneously.The captions demonstration of also can glimmering, and on the video pictures of playing that is added to.
2) static images
The prospect of this picture can be fixed or roll display on the video frequency program picture, its transparency 50%, and general spectators' vision can be seen the video frequency program picture that picture covers clearly by this picture, and the video frequency program picture does not influence the identification of this picture yet simultaneously.
3) motion picture
The prospect of this motion picture can be fixed or roll display on the video frequency program picture, its transparency 50%, general spectators' vision can be seen the video frequency program picture that motion picture covers clearly by this motion picture, and the video frequency program picture does not influence the identification of this motion picture yet simultaneously.
4) video segment
This video pictures is fixing the demonstration on the video frequency program picture, its transparency 50%, and general spectators' vision can be seen the current video program picture that video pictures covers clearly by this video pictures, and the video frequency program picture does not influence the identification of this video pictures yet simultaneously.
After the foreign medium fragment of intercutting also can be above-mentioned four any two or more groups in all types of, to increase advertising results.
Above-mentioned is to optimize from the image mode that advertisement is play, to portable terminal, the fluctuation of bandwidth remains a kind of problem that needs consideration, when mobile network's bandwidth fluctuation, the broadcast fluency of video frequency program is influenced bigger, but occupied bandwidth is also wanted in the advertisement of intercutting, and can aggravate the deficiency of bandwidth more.Therefore also to consider to be optimized from transfer of data.
The advertising segment that will play is inserted after video server downloads to this locality by video playing terminal again, after video server and video playing terminal are set up video and are connected, mutual by video playing terminal and video server, detect the bandwidth processing surplus on the video playing terminal in real time, and following mode is handled:
1, as connecting, but no video playing programs or video pictures suspend on the video playing terminal, the maximum code that video playing terminal is supported with current network bandwidth place immediately flows down carries the foreign medium clip file that is linked and is stored to this locality, if video playing terminal is recovered video playback in the downloading process, then reduce the code stream of downloading.
If 2 current network bandwidth fluctuate, or the increase of the video frequency program code stream of current broadcast, the code stream that the foreign medium fragment is downloaded then further reduced;
If the buffering phenomenon takes place in the video frequency program of 3 current broadcasts, then suspend the download of foreign medium fragment, when the rear video playback terminal has detected bandwidth gap later on, recover the download of foreign medium clip file, if the foreign medium clip file was not downloaded last time, then continuous the holding of breakpoint continues to download, and finishes up to download;
Above-mentioned foreign medium fragment is all downloaded on the backstage, does not influence the result of broadcast on video playing terminal foreground.
Because the broadband of wireless network is stable inadequately, sometimes fluctuation is bigger, after the broadband diminishes, if the code stream that video playing terminal received is too small, when being not enough to smooth playing, the video frequency program of current broadcast can cushion phenomenon, and this moment, video playing terminal began to play the foreign medium fragment that has downloaded to this locality, if buffering finishes, the broadcast that recovers video frequency program immediately.This will be avoided allowing in buffering course the user wait for, utilizes this time to play advertisement, allows the user have a rest, and advertisement is appreciated in the gap of rest.
Though comprised the specific embodiment of the present invention with technique scheme, but the those of skill in the art in the present technique field are to be understood that, these only illustrate, can make numerous variations or modification to these execution modes, and not deviating from principle of the present invention and essence, scope of the present invention is only by claims limit.
