This document discusses challenges with synchronizing distributed access (DA) network rollouts and video headend upgrades, and proposes a solution. It notes that DA rollouts are putting pressure on video headends to upgrade, but some DA rollouts are delayed. It also notes that existing broadcast equipment may need upgrading regardless of DA. The proposed solution is to upgrade broadcast equipment individually now using a technology that can serve both traditional and DA networks through an advanced EDGE QAM with R-PHY outputs and Video Core. This allows the equipment to be fully prepared for the shift to DA once rollout projects are completed, without compromising broadcast quality of service.

From challenges to solutions
Roll outs of distributed access networks cause pressure to upgrade video headends
• But some of these DA roll outs are delayed

Many existing video headends should be upgraded now, not only because of DA
• The currently used broadcast equipment might be expiring

Synchronizing DA roll out and video headend upgrade projects is difficult
• Broadcast and DOCSIS experts should work together under uncertain schedules

Proposition: it doesn’t have to be like this
• Broadcast equipment can be upgraded individually, now
• The equipment can be fully prepared for shift once the DA roll out projects take place

The technology behind the smooth shift
The same setup can serve traditional and DA networks
• Advanced EDGE QAM with R-PHY outputs (Video Engine)
• Video Core
Traditional broadcasting application
• Advanced EDGE QAM
• Supporting over 30 CAS
Usability and QoS on the same level as Broadcast engineers
have always taken for granted GCP

Relevant modules
Advanced EDGE QAM with R-PHY outputs (=Video Engine)
• Dense modulator (up to 28 QAMs per module)
• 28 muxes per module
• Remuxing and tunneling of local channels
• L2TP tunneling using DEPI
• Asynchronous mode supported
Luminato Video Core (Principal / Auxiliary)
• Uses GCP to configure RPDs for Broadcast Video reception
• Act as Principal Core in pure broadcast video setup
• Act as Auxiliary Core for broadcast video in multicore setup
• Supports RPDs reboot, SW update and RCP messages
• Shows status and state of connected RPD nodes

Summary
1. Instead of waiting until
”CCAP Core does everything” the
presented technology is available and
independently put into service
3. Robust broadcast grade hardware is ideal when fixed capacity is needed 24/7
4. Integrated EDGE QAM and Video Engine/Core serving today’s and tomorrow’s needs
2. DA roll outs should not compromise
Broadcast QoS Thank you!
