4-6 A system for TV broadcasting at trouble of IP network

Abstract

Broadband IP network is gradually making feasible video distribution services. Studying how to transmit TV programs if 1P network trouble like packet losses occurs is important. We propose a system which controls an amount of adding redundancy depending on the extent of network trouble to transmit at least what TV programs say. In this paper we make an estimate of an amount of adding redundancy to ensure target quality at a receiver.
