Triple Play System Basics • Data usage in Triple Play Systems Digital TV and radio data traffic • One TV-programtakes 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 GBon 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 about1GB 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 linein 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 0.05GB 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.
City-1/City-A Topology • Cell-based with sector antennas • 4 to 12 sectors in a TV cell
City-1/City-A Topology City-A • Cell radius: 3-4 km • 100 Mbps in downstream and upstream channels • Up to 12 sectors in a cell • ~50terminals per sector
City-1 Bandwidth • Total bandwidth - 3 GHz • 144 subbandsby 39 MHz on sector • 1 subband = 1 transponder = • 8 TV-channel of broadcasting quality • 45 Mbps for data tarnsfer • Total throughput per sector (72 subbands) • 576 TV-channels • 3240 Mbps • Total throughput percell • Up to 5000 TV-channels(VoD) • Up to 40 000 Mbps
Return channel • ELVA’s City-A System • 100 Mbps full-duplex • QoS • Up to 50 terminals
City-A Return channel abilities • Duplex Internet connection • Video overIP • Е1 overIP (up to 16xЕ1 per sector) • IP Telephony • Symmetrical data transfer (interactive games, etc)
