10. 3DTV IN THE NETWORK
• Needs 50-70% more
bandwidth than HDTV
• SDTV: 4-6Mbit CBR
• HDTV 1080p: 15-18Mbit
(BBC, Discovery)
• HDTV 720p:9 Mbit (NRK)
• 3DTV: Up to 32Mbit
• Inaddition to existing
HD channels
• Increased compression
means increased
sensitivity to jitter

with 2 packet losses
TID
90 % of all packet loss is due to “excessive jitter”

12. SUMMARY
• Plan ahead for 3DTV
• Consequences of jitter
and packetloss grow
exponentially from
SD→HD→3D
• Maintain full control from
play-out to Set Top Box
