【摘要】： P2P網(wǎng)絡(luò)中流媒體應(yīng)用的迅速發(fā)展,使得流媒體播放時(shí)插播廣告產(chǎn)生的價(jià)值得到快速增長(zhǎng),而先進(jìn)的廣告插播技術(shù)的研究,功能各異的廣告插播系統(tǒng)的應(yīng)用也不斷出現(xiàn)。流媒體廣告插播的效果,受廣告本身設(shè)計(jì),廣告插播策略,系統(tǒng)客戶端插播實(shí)現(xiàn)技術(shù)等因素影響。目前應(yīng)用的廣告插播系統(tǒng)多數(shù)是緩沖時(shí)插播,插播廣告多以預(yù)先設(shè)定或者廣告商的要求為主,并且在插播視頻廣告時(shí)無法支持動(dòng)態(tài)插播多個(gè)廣告。此外由于插播廣告會(huì)導(dǎo)致播放器在某一時(shí)刻在兩個(gè)視頻間進(jìn)行切換,如果切換時(shí)間超過一定長(zhǎng)度則會(huì)使得插播廣告產(chǎn)生用戶可以察覺的縫隙,而內(nèi)存消耗較大也是影響廣告插播系統(tǒng)應(yīng)用效果的一個(gè)因素。 為了能夠使廣告插播取得最佳的效果,該P(yáng)2P流媒體廣告插播系統(tǒng),不僅支持緩沖時(shí)廣告插播,還考慮到用戶長(zhǎng)久受電視廣告插播規(guī)律的影響,在流媒體播放較順暢的情況下,設(shè)計(jì)實(shí)現(xiàn)了定時(shí)廣告插播。根據(jù)廣告播放與睡眠效應(yīng)理論,插播與用戶觀看的流媒體資源相關(guān)性最大的,或者用戶自己設(shè)定的廣告視頻,并針對(duì)該需求,設(shè)計(jì)了視頻文本描述技術(shù),用來有效并相對(duì)準(zhǔn)確地計(jì)算兩個(gè)視頻的資源相關(guān)性。同時(shí)針對(duì)動(dòng)態(tài)插播多個(gè)廣告和無縫插播需求,并且盡可能節(jié)省系統(tǒng)內(nèi)存開銷,設(shè)計(jì)了流媒體主動(dòng)預(yù)取算法和基于磁盤輔助文件的動(dòng)態(tài)共享內(nèi)存池技術(shù),并應(yīng)用在廣告插播系統(tǒng)的客戶端。 P2P流媒體廣告插播系統(tǒng)從廣告插播策略,客戶端實(shí)現(xiàn)技術(shù)等方面做了大的改進(jìn),最大程度的克服了現(xiàn)有常規(guī)插播系統(tǒng)的弊端,實(shí)現(xiàn)插播方式友好、節(jié)省內(nèi)存、無縫的廣告插播。該廣告插播系統(tǒng)的應(yīng)用拓展了廣告發(fā)布的領(lǐng)域,提高了廣告的影響力,增加了廣告商的客戶量,使P2P流媒體運(yùn)營(yíng)商具有更強(qiáng)的競(jìng)爭(zhēng)力。
[Abstract]:The rapid development of streaming media application in the P2P network makes the value of the advertisement in the streaming media play a rapid growth, and the research of the advanced advertising and broadcasting technology and the application of the different functions of the advertising and broadcasting system. The effect of the streaming media advertisement is designed by the advertisement itself, the advertisement sowing strategy, the system client. Most of the advertisement sowing systems currently used are buffering and sowing, which are mostly preset or advertisers, and can not support dynamic broadcasting of multiple advertisements during video advertising. In addition, the player can lead the player to two videos at a certain time. In line switching, if the switching time exceeds a certain length, the slot advertising can be produced by the user, and the large memory consumption is also a factor that affects the effect of the application of the advertisement system.
In order to make the best effect of advertising sowing, the P2P streaming media advertising and broadcasting system not only supports the buffering of advertising sowing, but also takes into account the long-standing influence of the users on the rules of TV advertising, and the design and implementation of the timing ad sowing. The maximum relevance to the streaming media resources viewed by the user, or the ad video set by the user itself, has been designed to effectively and accurately calculate the resource relevance of the two videos for the demand. It also aims at the dynamic interpolation of multiple broadcast and seamless demand, and saves the system as much as possible. Memory overhead, the streaming media active prefetching algorithm and the dynamic shared memory pool technology based on disk auxiliary files are designed and applied to the client of the advertisement insertion system.
The P2P streaming media advertising and broadcasting system has made great improvements in the aspects of the advertising and broadcasting, the client implementation technology and so on. It overcame the disadvantages of the existing conventional broadcasting system to the greatest extent, and realized the friendly, saving and seamless advertisement inserting. The application of the advertising and broadcasting system expanded the field of advertising and improved the advertising. Influence has increased advertisers' customers and made P2P streaming operators more competitive.
