The document discusses the benefits of using lower bitrate video encoding, specifically comparing H.264 and H.265 codecs, and highlights the significant cost savings on CDN distribution. It emphasizes the growing demand for live video streaming and the increased encoding capacity required to handle this growth. The Codensity T400 video transcoder is introduced as a solution that offers high-quality, efficient encoding at reduced costs, integrating advanced technologies for better scalability.

▪ Example: Monthly distribution cost for 1080p30 continuous live video stream
• Compares CDN costs for H.264 vs H.265 encoded video of similar quality
▪ CDN distribution costs $0.02 per GB1
Average viewership 1,000,000 100,000 10,000 1,000 1
CDN Costs for 8 Mbps (H.264 AVC, 1080p30) $ 51,840,000 $ 5,184,000 $ 518,400 $ 51,840 $ 51.84
CDN Costs for 4 Mbps (H.265 HEVC 1080p30) $ 25,920,000 $ 2,592,000 $ 259,200 $ 25,920 $ 25.92
CDN Savings $ 25,920,000 $ 2,592,000 $ 259,200 $ 25,920 $ 25.92

4. Drivers for Encoding and Transcoding Capacity Growth
▪ 15x Growth in Live Video1, 2016-2021
Encoding Capacity Growth will be higher:
▪ More high compression codecs
will require more encoding processing power
• H.265 HEVC = ~10x more processing vs H.264 AVC
▪ More high resolution videos
will require more encoding processing power
▪ User Generated Content (UGC) growth
• Each UGC input stream requires encoding

H.265 encoding with
Intel QSV
• Improved density
H.265 encoding on GPU
• Improved density and
capacity
• Form factors and power
consumption make GPU
hard to scale
H.265 encoding on FPGA
• Improved density and
capacity
• Better power efficiency
• Requires packaging of
FPGA somewhere inside
host server or
proprietary hardware
H.265 encoding on ASIC
(Codensity G4 SoC)
• Best density, Lower cost
• Best real-time performance
80% less power
x265 software encoding on CPU
• Lowest density and capacities
• Huge resource requirements are
economic limitation to
scalability
• Highest $ per stream

Introducing
Codensity™ T400 Video Transcoder

8. Codensity T400 Video Transcoder
Scalability through innovations in SSD cloud storage
▪ HDD -> SSD
▪ SATA/SAS -> NVMe
• NVMe is extendible for other applications
▪ U.2 is common form factor for SSDs
▪ Solution scales using NVMe storage servers
• But instead of adding U.2 SSD modules,
you add U.2 T400 transcoder modules
▪ In this example configuration,
• 10x T400 modules installed in 1U server
• 80x 1080p30 H.265 sessions* (in 1RU!)

NVMe = Non-Volatile Memory express = High throughput, low latency protocol developed for SSD control

9. Codensity T400 Video Transcoder – Encoding Quality
Codensity T400 delivers high real-time video encoding quality,
at much higher density compared to alternative solutions
