Abstract

Спосіб оптимізації передачі програми багатьом користувачам полягає в тому, що передають програми через систему розподілення. В головній частині системи розподілення формують програму, розділену на множину програмних сегментів для реалізації алгоритму планування, який розміщує програмні сегменти у заданій послідовності. Передають програмні сегменти згідно алгоритму планування з можливістю одночасної передачі будь-якого сегмента більш, ніж одному приймачу. Впродовж часу, необхідного для нормального відтворення програми, принаймні, частину програмних сегментів передають більше одного разу одночасно до кількох приймачів без закріплення в будь-який момент часу головного вузла і системи розподілення за яким-небудь окремим приймачем. В приймальній частині системи розподілення проводять запам’ятовування переданих програмних сегментів у буферному ЗП приймача для наступного відтворення. За рахунок цього вказаний алгоритм планування, при його використанні, може гарантувати приймання будь-яким приймачем всіх програмних сегментів з можливістю послідовного відтворення програми з нормальною швидкістю з одночасним забезпеченням трансформованості структури буферного ЗП, ємність якого буде меншою ємності, яка містить всю програму цілком.
