• Avanci Video

Licensing can affect:

• Encoder deployment
• Device manufacturers
• Content distribution costs

Before adopting VVC, streaming businesses should:

• Review pool terms
• Understand per-device vs content royalties
• Model long-term ROI vs bandwidth savings

Real-World Bandwidth Impact

Let’s compare 4K streaming:

If 100 hours of 4K HEVC = ~1 TB
VVC at ~45% savings = ~550 GB

For high-volume platforms, that translates to:

• Major CDN savings
• Lower storage costs
• Reduced carbon footprint

VVC is particularly compelling for:

• 4K sports
• 8K pilots
• UHD VOD libraries
• Global low-bandwidth regions

Sustainability & Green Streaming
