broadband triple play
Broadband Triple Play
  • Triple play?
    • TV, Internet, Phone ( Video as part of TV & Internet)

ISP/Telco Model Computer/Telephone Centric

Cable Model TV Centric

Cost of accessing services may only be related to type of services and not to the city or distance from the local point of service

  • MSO (multi-service operators) investing not only in networks, equipment and external plant but also in application servers, delivery mechanisms, content, application development, additional build-ups ?
interesting broadband scenarios
Interesting Broadband Scenarios
  • Hong Kong Population 6.8 million, Household 2.2 million

Broadband connections 1.2 million (1.1 million house hold) 14 DSL lines/100 population; 28 DSL lines per 100 telephone lines

  • In Japan BB driven by content for different age groups
  • In Korea BB driven significantly by local content
  • Access owner- service provider - content provider
  • Revenue as ratio of investment in that order
  • In India BB may be driven by Entertainment: Interactive TV , time-shift TV, video on demand, music on demand, multiplayer gaming, education at home, sky shop rather than internet shopping. Of course net browsing and data transfer.
  • How much symmetrical !
