Broadcast Distribution Systems Using Overlay Networks
- Distribution networks that meet regional needs -
  Overview
  STRL is researching using overlay networks*1 to provide broadcasting over the Internet. The use of overlay network technology make it easier to provide disaster prevention and emergency information to specific areas of affected municipalities. Distribution network management technology facilitates smooth switching between networks when going from national to regional broadcasts.
  Merits
  • Distribution network management technology enables nationwide broadcasts and regional broadcasts over the Internet.
  • It builds efficient distribution nationwide and regional networks.
  • It cuts waiting time before switching is completed and minimizes network switches in going from national broadcasts to regional broadcasts.
  Future Plans
  We will verify the distribution method on the Internet and develop a high-functionality distribution system.
*1 Overlay networks: Networks that are built upon other networks. For instance, peer-to-peer connections can be used to create a peer-to-peer network.
