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, it’s bring 0.05 GB traffic per day.

Triple Play System Basics (3) Data usage in Triple

Play SystemsData 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.
