IPTV 서비스의 진화 : Personalization, Community and Communication Service
IP-TV/TPS Service 배경
서비스와 네트워크간에 1:1 관계
MSO: (TPS Service 경쟁)
Telco는 1+1+x
Telco’s IP-TV/TPS Service
TV over STB: IP-TV, VoD, N-PVR, PoD
POTS or SIP Phone: VoIP, MMoIP

Problem
단순 TV 서비스, VoD 서비스를 위해 기존 Telco는 망 증설 (용량, 기능)에 막대한 CAPEX 투입: Telefonica, KT, SBC, BellSouth,…
CAPEX를 회수할 만한 BM이 있는 가?
기존 방송 사업자와 차별화된 서비스 발굴이 핵심 이슈
IP-TV 서비스의 진화

Personalization: My Own Mosaic Channel, Content Sharing (MyOwnTV)
Community: AmigoTV, KT TV 메신저, Active Phonebook
Communication: TV 메신저, MMoIP, Click-to-Call, Caller ID

- Internet (CM) Subscribers: 2.3 M (2005.Q2)
- Voice Subscribers: 1.5M (2005 Q2)
- TPS (TV, Voice, Internet) Subscribers: 1M ( )
Source:
Cox Communications Inc. said Monday that more than 1 million customers subscribe to its “triple-play” bundle of voice, video and Internet services. ( )
Cox has found, for example, that customer churn in households that subscribe to two services, such as cable and Internet, is 18% lower than in one-product households. And when customers subscribe to all three offerings--video, high speed Internet and telephone service--customer churn is 48% lower. (2005)
Bundled customers are defined by those taking two or three of video, high-speed Internet or phone services.
2.4 M bundled customers: up to 33% over prior year
TPS Service의 신규 가입자 유치, 기존 가입자 이탈 방지 효과를 시장에서 입증됨.

36. Caller ID (IPTV + Voice)
You are watching TV at home and the phone rings.
A caller ID flashes on the screen and, because you see it is someone you don’t want to speak to (the so-called ‘Mr. Kim’) you forward the caller — with a click on the remote control — to voice mail.
Alternatively (if it wasn’t Mr. Kim), this call could be directed to your phone or taken on the remote control itself.
TV screen shows Caller ID information.
Consumers control the voice call with a remote controller.
