Description
Technical field
The present invention relates to barrage control field more particularly to a kind of barrage supplying systems and method for pushing.
Background technology
Barrage (barrage), Chinese vogue word, original meaning refers to provides intensive bombardment with a large amount of or a small amount of cannon.Largely with
The phenomenon that comment that subtitle form is shown occurs simultaneously also referred to as barrage.
Barrage video system is originated from Japanese barrage video sharing website (niconico animations), and domestic introduce first is
AcFun (content masses are polynary) and later bilibili (newborn Quadratic Finite Element to barrage net).
It is a large amount of spit slot comment from screen sail when effect look like barrage in flight shooting game, so NICO nets
The people have a large amount of effect spat when slot comment occurs to do barrage by this.In China, original only a large amount of comments occur just simultaneously
Barrage can be, but as misuse single comment can also be barrage.
It is typically considered to be intended that gun fire shooting intensive in military speak at home, it is excessively intensive so that pitching a tent as one
Cloth is the same.English claims " Bullet Hell " (bullet hell) or " Bullet Curtain " (barrage).Barrage is militarily in fact
Refer to tactics when artillery policy (barrage) rather than infantry tactics or air defense shooting.Then, spool shooting game and clear version
Game is this because of all having the characteristics that mostly, is referred to as barrage game or barrage game.With the end of last century《East
Project》To represent, play this making type commonly using barrage in playing with people, this be barrage this word most
The early source for entering ACGN circle.
At present, barrage has become a kind of characteristic of specific player, and barrage system is then the core of barrage player.
However, since if barrage is without correct guiding, the speech environment of exploitation will bring certain social harm, because
This, needs to increase barrage pattern authentication mechanism to ensure that only authorized user can use video playback apparatus to carry out barrage behaviour
Make.In the prior art and there is no such authentication schemes.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of barrage supplying systems, and video of the prior art is transformed and broadcasts
Equipment is put, the mirror of a set of barrage pattern is built by the network communication technology for introducing high-precision face recognition technology and high bandwidth
Mechanism is weighed, bad speech is issued so as to which unauthorized user be avoided to enter barrage pattern using video playback apparatus, this ensure that
It can abide by the law and public order and good custom in the speech of public space.
According to an aspect of the present invention, provide a kind of barrage supplying system, the system comprises video playback apparatus,
MSP430 microcontrollers and barrage pushing equipment, barrage pushing equipment are connect with video playback apparatus, for video playing to be controlled to set
Standby whether to carry out barrage pattern, MSP430 microcontrollers connect to control barrage pushing equipment with barrage pushing equipment.
More specifically, in the barrage supplying system, including：Video playback apparatus, for playing video and there is bullet
Curtain pattern and normal mode, video playback apparatus play the video pictures of no barrage, video playback apparatus in normal mode
The video pictures for having barrage are played under barrage pattern；MSP430 microcontrollers, respectively equipment more sub- with feature vector and barrage
