High-definition IPTV Broadcasting Architecture over Gigabit-capable Passive Optical Network Author: Ikeda, H. Sugawa, J. Ashi, Y. Sakamoto, K. From: Global Telecommunications Conference, 2007. GLOBECOM '07. IEEE Presented by: Zhi-Sheng, Lin

Outline Video content delivery technology High-definition IPTV broadcasting architecture Multicast address management for broadcasting service GPON and IP multicast cooperative broadcast Fast IPTV channel selection Evaluation and implement Conclusion

Video content delivery technology Three types IP broadcasting Video-on-Demand (VoD) File download Some access network used to delivery video content EPON, GPON, BPON. Radio frequency (RF) overlay.  Hybrid fiber coaxial (HFC) Network Be able to save bandwidth Waste a lot of bandwidth

Video content delivery technology RF overlay technology Advantage: Use the same format that a CATV of satellite provider uses. Disadvantage: Complex equipment required. Hybrid infrastructures. This paper proposes A HD IPTV broadcasting system in GPON. A management method of IP multicast address. Fast channel switching.

High-definition IPTV broadcasting architecture Provide IPTV channel URL Local service provider’s office (VHO) Local central office (VSO)

High-definition IPTV broadcasting architecture According to user’s profile at the ONT

High-definition IPTV broadcasting architecture This architecture includes (1/2) IP broadcasting server Packetizes video contents into multicast IP packets. GPON OLT encapsulates an IP multicast packet into a Gigabit Ethernet Module (GEM) frame with multicast port IDs. IPTV terminal An IP broadcasting channel is selected with IPTV channel information (IPTV channel Uniform Resource information (URL))

High-definition IPTV broadcasting architecture This architecture includes (2/2) IPTV portal server A web server which provides the IPTV channel URL. IP broadcasting management server Manages the multicast address of IP broadcasting channels. Thus, the service provider can control the broadcasting area for video content.

Multicast address management for broadcasting service A. IP broadcasting management server (scalable) Ex: Ch-01@IPS.co.jp corresponds to IP multicast address 239.255.255.1

Multicast address management for broadcasting service

Multicast address management for broadcasting service

Multicast address management for broadcasting service Benefit: reduce the burden of informing IPTV terminals of updating multicast address information.

Multicast address management for broadcasting service B. IP broadcasting terminal Use local cache to improve multicast address query time.

Multicast address management for broadcasting service

GPON and IP multicast cooperative broadcast

Fast IPTV channel selection

Evaluation and implementation

Evaluation and implementation The ratio of the broadcast traffic

Evaluation and implementation IP broadcasting server  five HDTV streams output Channel selection function in the ONT Web-based IP broadcasting management server IP client with an IPTV channel URL to IP multicast address translation. Reslut: The channel selection speed was less then 10 msec.

Conclusion Support triple play. Single broadband IP network infrastructures. Achieve 10-msec IPTV channel selection time.
