BROADCAST DISTRIBUTION SYSTEM, BROADCAST DISTRIBUTION METHOD AND NETWORK DEVICE

摘要

PROBLEM TO BE SOLVED: To simulcast broadcast via an IP network.;SOLUTION: In a distribution system where an IP encapsulator 2 divides broadcast data provided by a video distribution source 1 into packets to convert the broadcast data into an IP capsule and transmits it to a subscriber line terminal 12 via a network 3, memory capacity is minimized to shorten delay time by providing the subscriber line terminal 12 with a memory function for accumulating broadcast data and performing ToS control and transfer path switching control based on an accumulated state of the memory.;COPYRIGHT: (C)2008,JPO&INPIT
