Triple Play System Basics

• Data usage in Triple Play Systems
• Digital TV and radio data traffic
• One TV-program takes 6.0-6.5 Mbps per one TV
  channel channel.  The average TV is on 4
  hours/day, it is corresponded to receiving 10 GB
  information per day.
• One movie on CD takes 0.6 GB, and 5 GB on DVD
  disk.
• One digital radio channel takes 384 Kbps. The
  average radio is on 4 hours/day, it is
  corresponded to receiving 0.7GB information per
  day.

Triple Play System Basics (2)

• Data usage in Triple Play Systems
• Internet and telephone traffic
• An average Internet download traffic for home PC
  is about 1GB per month or 0.03 GB per day.
• A telephone takes 8 Kbps per one line. For
  example, an average usage of one home phone line
  in Russia is 15 minutes per day, in other words
  one line requires 0.001 GB traffic per day.
• The videophone takes 384 Kbps, like a radio
  channel. When using same 15 minutes per day, its
  bring 0.05 GB traffic per day.

Triple Play System Basics (3)

• Data usage in Triple Play Systems
• Data usage analysis
• For a 1-millon city with 30 digital TV channels
  and 20 radio channels broadcasted let we assume
• Telephone has 50 of population
• Home PC have 20 of population
• Videophone and video on demand equipment have 5
• Each building allocates 300 phones and PCs and up
  to 75 videophones
• Each terminal eats 200 Mbps
• Downstream traffic 200 times bigger than upstream
  one

Triple Play System (4)

• What is the decision to build Triple Play?
• Deploy City-1 and City-A systems on the same
  territory!
• Duplex traffic is just 1Mbps per terminal. To
  support duplex traffic, deploy Ethernet-based
  Point-to-Multipoint City-A system.
• It takes care on upstream Internet, telephones,
  videophones traffic and video-on-demand return
  channel.
• The per second traffic per the whole city will be
  1Gbps according to a.m. assumptions.
• Simplex traffic (downstream traffic) can be fed
  by Point-to-Multipoint City-1 system.
• It takes care on downstream digital TV, radio and
  video on demand traffic.
• TV channels could be distributed within a
  building either by coaxial cables (DVB) or UTP
  cables (IP).
• The per second traffic per the whole city will be
  10Gbps according to a.m. assumptions.
