Description
Technical field
The present invention relates to the video stream media application, especially relate to a kind of method that is dynamically embedded into other media fragments in the video program play picture.
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 broadband internet, digital tv network, mobile phone 3G network is universal gradually, and the video stream media industry will welcome a unprecedented opportunity to develop.Mobile Internet is development trend from now in addition, and the problem of mobile Internet maximum is that bandwidth is little and fluctuation is large, even in the 3G epoch, the restriction of wireless bandwidth and fluctuation remain the key factor that will consider in video playback.Compare with wired internet, the resource of wireless bandwidth is that cost limited and that use is higher, and the network service project of many new releases will obtain repayment, must make rational profit model.The video frequency program resource of present interconnected Free Online is more and more abundanter, provides service iff the charge that relies on video frequency program itself to the netizen, and 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 breaks for commercialsy in video frequency program with long-term existence.But this practice also has many defectives: the one, break for commercialsy in the program playing process, concerning most of spectators, the advertisement of intercutting has been formed for a long time resisted psychology, advertisement has become the resting machine meeting in the middle of 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 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 affected by these factors, if the Internet video program is indiscriminately imitated the pattern of television advertising, possible effect is poorer than television advertising.Because watching video program on the mobile terminals such as mobile phone, the user can control the playing progress rate of video frequency program fully, and the user just can skip the web advertisement that intercuts easily.Therefore will solve a problem, allow the free watching video program of user, 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 that the video playing terminal by video server and displaying video information forms, video server sends video program information when playing on video playing terminal, other media fragment content can be inserted in progress video frequency program, play with screen on video playing terminal, comprise the steps:
(1) set 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 a classification, all classifications and subclass all have the item name that can distinguish, 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, this video program data comprises a video frequency program file in the storehouse at least, 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 insert other foreign medium fragments in the video frequency program of playing;
(3) be that each timestamp in video frequency program distributes corresponding foreign medium fragment link, timestamp in video frequency program also is divided into identical classification sequence, and system associates the timestamp classification in foreign medium fragment classification and video frequency program automatically; This being associated with is beneficial to the input that realizes the sorter network advertisement in video frequency program, can come in ad content is related with video content, and the effect of enhancing advertisement.When being a ball match as the content of video playback, can intercut the sports goods advertisement.
(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 lower advertisement, allow the user watch advertisement by the mode of forcing, and is the most serious to user's interference.
Mode two: mark off a new play area on the screen of video playing terminal, play the foreign medium fragment of link in new play area, 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 TV, because mobile terminal screen is generally less, the advertisement broadcast window is unsuitable excessive, otherwise the obvious user of impact is watched video frequency program, cause that the user resists, can affect 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, as the captions advertisement on picture, watches the video frequency program impact minimum on the user.
Consider that most of user has to the advertisement of intercutting in video the psychology of resistance, optimize advertisement as far as possible and experience, alleviate the interference to the user.Therefore in the mode three of aforesaid step (4), the foreign medium fragment that superposes is the all-transparent background, and its prospect is presented on the video frequency program picture of current broadcast in floating mode.After adopting transparent background, only have a part of video pictures of prospect impact of advertisement picture, when product figure is arranged in advertisement picture, only have the product profile to be presented on video pictures, alleviated the video interference.
Above-mentioned video is disturbed and can further alleviate, and the prospect of the foreign medium fragment that superposes is translucent, and its transparency can be regulated between 0 to 100%.When product figure was arranged in advertisement picture, the product image was also translucent, saw through the product image, also can watch video pictures.
Due to the brightness of the picture of the video frequency program of playing generally according to the content change of video pictures scene, as darker in picture in the scene in evening, brighter under the sun, if if this moment advertisement picture brightness and transparently do not adjust, will contrast excessive, the video frequency program of playing is caused interference.Therefore to further optimize technique scheme, the transparency of the prospect of the foreign medium fragment that superposes and brightness are regulated according to the current video frequency program picture brightness of playing automatically by video playing terminal, and 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 superposeing not exclusively hides the video frequency program picture.This advertisement picture that will intercut is adjusted self transparency and brightness with the luminance dynamic of video frequency program, also the program picture combines together, has alleviated interference.
Above-mentioned foreign medium fragment is for can be divided into as Types Below:
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 affect the identification of captions yet simultaneously.Captions also can flickering display, 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 affect 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 affect 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 affect the identification of this video pictures yet simultaneously.
After the foreign medium fragment of intercutting can be also 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 in real time the bandwidth processing surplus on video playing terminal, and following mode is processed:
As built vertical connection, but suspend without video program play or video pictures on 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 in downloading process, video playing terminal is recovered video playback, 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 further reduced;
If the buffering phenomenon occurs in the video frequency program of current broadcast, suspend the download of foreign medium fragment, when video playing 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, breakpoint continues to continue to download, until download complete;
Above-mentioned foreign medium fragment is all downloaded on the backstage, does not affect the result of broadcast on video playing terminal foreground.
Because the broadband of wireless network is stable not, sometimes fluctuation is larger, after the broadband diminishes, if the code stream that video playing terminal receives 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 of immediate recovery video frequency program.This will be avoided allowing the user wait in buffering course, utilizes this time broadcast 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 in the present invention to be dynamically embedded into technology, can make intercutting of optimized network advertisement, and the web advertisement and video frequency program are organically combined, and alleviates the annoyance level to video playback.

Understand and implement the present invention for the ease of those of ordinary skills, the present invention is described in further detail below in conjunction with reaching by reference to the accompanying drawings embodiment.
Along with the continuous increase of the network bandwidth and the 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 network is all generally from freely, and service provider generally places on profit 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 and the user is watched the interference of video frequency program.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 effectively alleviated the interference of the web advertisement to spectators, and improved to greatest extent the effect of the web advertisement.
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, namely set up a web advertisement database.
can use the SQL database system, one of database master meter can be a web advertisement table, comprise " advertisement numbering, the advertisement title, adline, the advertisement classification, ad content, the advertisement state " etc. field, 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, clothing " etc., can the little classification of nested multilayer under a large 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 is only to be made of text character, and modification can be with in word.If the advertisement of other type, field " ad content " is comprised of word and picture.
Step 2: set up a video program data storehouse and insertion of advertising timestamp.
this database is exactly the video frequency program resources bank, comprised video frequency program file to be played, for the web advertisement is sown in video program content, need to be to definition time spot stamp in video pictures, this timestamp can be distributed automatically by system, it is the video frequency program of 100 minutes as a reproduction time length, if evenly intercut 9 web advertisements, will stab the time spot and be distributed in the " 10 of video program play, 20, 30 ... 90 " minute locate, 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, 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 video frequency program distributes corresponding foreign medium fragment link, the timestamp in video frequency program also is divided into identical classification sequence, system associates the timestamp classification in foreign medium fragment classification and 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 the relay video for a ball match, sports goods advertisement that can related correspondence.
Step 4: insert the web advertisement during video program play.
The time spot stamp that inserts in step 2 is used for the playing network advertisement, the web advertisement can embed or be added in video pictures, watch video frequency program in order not affect the user, the web advertisement can be play on any one edge on four limits of video program play terminal screen, roll display as following in screen.The method of inserting the web advertisement can have following several:
1, radom insertion
Time spot of the every arrival of the process of video program play is when stabbing, extract a web advertisement and insert and play at random 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
Time spot of the every arrival of the process of video program play is when stabbing, extracting in order a web advertisement from web advertisement storehouse inserts and plays, in a playback period, each web advertisement is all play once, and when played in order, the advertising results of more forward 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, and when even the user only saw the video frequency program of front, the advertisement of back had not just had the chance of broadcast.
3, classified advertisement is inserted
Advertisement segmentation pattern on above-mentioned random or played in order pattern basis, when time spot of the every arrival of the process of video program play stabs, according to the classification of time spot stamp 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 is also a kind of advertisement segmentation pattern on above-mentioned random or played in order pattern basis, set up in advance specific web advertisement link on the time spot stamp, when the specific time spot of one of the every arrival of the process of video program play during stamp, extract the specified web advertisement of link according to the link of time spot stamp and insert and play from web advertisement storehouse.
5, the condition trigger-type inserts
The trigger condition of an advertisement insertion is set in audio/video player system, this trigger condition can be special sound or the image that occurs in special time or video pictures, be that video frequency program is when live, a testing conditions is set, picture image and sound when detecting program sending by video server, in case qualified picture or sound detected, 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 the Rule of judgment (if any license plate number or wheel characteristics) that certain object that moves that occurs on video pictures meets car detected, just automatically insert the web advertisement of playing a relevant car.
6, targeted ads inserts
The user is when the order video program, system's automatic lifting is taken the on-site IP of online address, family, therefrom analyze the area of user's online, when the video program play process arrives a time spot during stamp, system inserts a targeted ads of throwing in towards this user location automatically in the video frequency program of current broadcast.Here need to set up an IP address ownership place database in system, constantly update and safeguard, guarantee that the IP address can accurately represent user's source place.The IP address that the user online of certain order video program detected as system is 202.96.133.xxx, system retrieval IP address ownership place database, find this user from Shenzhen, the web advertisement that in the video frequency program of just watching to this user, inserting surface is thrown in to Shenzhen area.
In addition, can take full advantage of the digitalized signature of network video advertisement, strengthen in the following manner the experience effect of advertisement, allow spectators be easy to accept.
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 lower advertisement, allow the user watch advertisement by the mode of forcing, and is the most serious to user's interference.Do not advise adopting in practice the advertisement mode of this mode.
Mode two: mark off a new play area on the screen of video playing terminal, play the foreign medium fragment of link in new play area, 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 TV, because mobile terminal screen is generally less, the advertisement broadcast window is unsuitable excessive, otherwise the obvious user of impact is watched video frequency program, cause that the user resists, can affect 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, as the captions advertisement on picture, watches the video frequency program impact minimum on the user.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 remind or annotate AD tagged.
Consider that most of user has to the advertisement of intercutting in video the psychology of resistance, optimize advertisement as far as possible and experience, alleviate the interference to the user.Therefore can further adopt technological means to alleviate above-mentioned commercial breaks and spectators be watched the impact of video frequency program, can be by adopting transparent advertisement picture pattern.
1, transparent background advertisement
The foreign medium fragment that superposes is the all-transparent background, and its prospect is presented on the video frequency program picture of current broadcast in floating mode.After adopting transparent background, only have a part of video pictures of prospect impact of advertisement picture, when product figure is arranged in advertisement picture, only have the product profile to be presented on video pictures, alleviated the video interference.
2, the translucent prospect advertisement under transparent background
Above-mentioned video is disturbed and can further alleviate, and the prospect of the foreign medium fragment that superposes is translucent, and its transparency can be regulated between 0 to 100%.When product figure was arranged in advertisement picture, the product image was also translucent, saw through the product image, also can watch video pictures.
3, the automatic adjusting of advertisement foreground to transparent degree and brightness
Due to the brightness of the picture of the video frequency program of playing generally according to the content change of video pictures scene, as darker in picture in the scene in evening, brighter under the sun, if if this moment advertisement picture brightness and transparently do not adjust, will contrast excessive, the video frequency program of playing is caused interference.Therefore to further optimize technique scheme, the transparency of the prospect of the foreign medium fragment that superposes and brightness are regulated according to the current video frequency program picture brightness of playing automatically by video playing terminal, and 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 superposeing not exclusively hides the video frequency program picture.This advertisement picture that will intercut is adjusted self transparency and brightness with the luminance dynamic of video frequency program, also the program picture combines together, has alleviated interference.
Above-mentioned foreign medium fragment is for can be divided into as Types Below:
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 affect the identification of captions yet simultaneously.Captions also can flickering display, 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 affect 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 affect 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 affect the identification of this video pictures yet simultaneously.
After the foreign medium fragment of intercutting can be also above-mentioned four any two or more groups in all types of, to increase advertising results.
Above-mentioned is to be optimized from the image mode that advertisement is play, to mobile 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 larger, but occupied bandwidth is also wanted in the advertisement of intercutting, and can more aggravate the deficiency of bandwidth.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 in real time the bandwidth processing surplus on video playing terminal, and following mode is processed:
1, as built vertical connection, but suspend without video program play or video pictures on 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 in downloading process, video playing terminal is recovered video playback, 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 further reduced;
If the buffering phenomenon occurs in the video frequency program of 3 current broadcasts, suspend the download of foreign medium fragment, when video playing 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, breakpoint continues to continue to download, until download complete;
Above-mentioned foreign medium fragment is all downloaded on the backstage, does not affect the result of broadcast on video playing terminal foreground.
Because the broadband of wireless network is stable not, sometimes fluctuation is larger, after the broadband diminishes, if the code stream that video playing terminal receives 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 of immediate recovery video frequency program.This will be avoided allowing the user wait in buffering course, utilizes this time broadcast advertisement, allows the user have a rest, and advertisement is appreciated in the gap of rest.
Although comprised the specific embodiment of the present invention with technique scheme, but those of skill in the art in the art are to be understood that, these only illustrate, can make various changes or modifications 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.
