【摘要】：對(duì)美國(guó)ATSC3.0系統(tǒng)中新制定的鏈路層協(xié)議(ALP)進(jìn)行了介紹,對(duì)其協(xié)議格式和特點(diǎn)進(jìn)行了詳細(xì)的說(shuō)明。針對(duì)TS數(shù)據(jù)包封裝的部分進(jìn)行了封裝效率的理論分析,進(jìn)一步針對(duì)理論分析的結(jié)果進(jìn)行了實(shí)驗(yàn)仿真。對(duì)于實(shí)驗(yàn)仿真所發(fā)現(xiàn)的在多視頻流封裝時(shí)效率低下的問(wèn)題提出了解決策略,使得ALP協(xié)議對(duì)于多視頻流封裝的封裝效率提升了接近1%。
[Abstract]:The new link layer protocol (ALP) in American ATSC3.0 system is introduced, and its protocol format and characteristics are described in detail. The efficiency of TS packet encapsulation is analyzed theoretically, and the results of theoretical analysis are simulated. In order to solve the problem of low efficiency in multi-video stream encapsulation found by experiment simulation, the efficiency of ALP protocol for multi-video stream encapsulation is improved by nearly a bit.
