2. 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

3. 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

4. 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.

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

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

7. 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))

8. 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.

9. Multicast address management for broadcasting service
A. IP broadcasting management server (scalable)
Ex: corresponds to IP multicast address

10. Multicast address management for broadcasting service

11. Multicast address management for broadcasting service

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

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

14. Multicast address management for broadcasting service

15. GPON and IP multicast cooperative broadcast

16. Fast IPTV channel selection

17. Evaluation and implementation

18. Evaluation and implementation
The ratio of the broadcast traffic

19. 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.

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