Shotsberger (2000) reported that though it took radio 38 years to reach
50 million listeners, it only took TV 13 years to reach 50 million viewers
The storm is a’ coming
The Internet took 4 years, iPod took 3 years, Facebook added 100 million
users in less than 9 months and iPhone applications hit 1 billion in 9
months
Gartner predicts that through 2014, improved JavaScript performance will
begin to push HTML5 and the browser as a mainstream enterprise
application development environment. Richer voice and video that can
connect people in new and different ways.
Gartner identifies four basic usage models that are emerging:
Manage, Monetize, Operate & Extend. These can be applied to
people, things, information, and places, and therefore the so called “Internet
of Things” will be succeeded by the “Internet of Everything.”

Typical Diagram of Analog TV

Existing Pay TV Industries

 Based on Pyramid Research, Indonesia's pay-TV market is characterized by a very low
household penetration, which reached only 3 percent in 2010.
 This figure possible to be expanding to 7 percent by 2015, driven by an improving
economic situation and the greater market competition since PT Telkom-owned
Telkomvision entered the market in 2007.
 Currently Indovision, Telkomvision and First Media dominate the market, with about 95
percent of total pay-TV subscribers in 2010.
 Some other Pay TV providers via DTH : Direct Vision, Aora TV, OK Vision, B-Vsion,
Topas TV are coloring the market,
 Cable TV operators : First Media (Kabelvision), Telkomvision, Indosat Mega Media (IM2)
and Cepat Net (Moratelindo).
 Despite benefiting from Telkom's ability to offer triple-play bundles, IPTV will account for
only 6 percent of total pay-TV accounts by year-end 2015.
 The country's geography structure is archipelagic, so DTH technology based will remain
the dominant technology, accounting for about 88 percent of total pay-TV subscriptions
through 2015.

Digital television in Indonesia will start to be fully implemented in
2018. Therefore, there are several steps that must be made towards
the implementation of digital broadcasting.
 First Phase 2009-2012 period, in the form of broadcast simulcast which is broadcast
together between analogue and digital (simulcast period).
 Permit termination for the operation of analog TVs after a new license of the
digital TV infrastructure providers.
 Starting with a new license for digital TV providers infrastructure
 Encourage the domestic electronics industry in the provision of TV receiving
equipment
 Second Phase In 2013-2017, a number of analogue broadcasts in some areas will be
turned off and intensification of a new license for digital TV providers infrastructure
 Final Phase, starting 2018, all analogue broadcasts will be turned off.
 Digital TV will be fully operated in UHF Band IV and V.
 The rest UHF channel will be used for advance wireless telecommunication
(International Mobile Telecommunication & Public Protection Disaster Relief).
Three Phases Migration to TV Digital

 Migration Roadmap, the detail time frame for migration (the transition period and the
analog cut-off).
 Coordination - Nationally and within each Television Broadcasting.
 Frequency Planning for Digital TV Broadcasting
 Policy of SFN and co-located systems
 Single tower policy;
 Determination of the format SDTV, HDTV or both are multiplexed in one channel.
 Selection of MPEG2 or MPEG4 compression system
 Proposal from some existing broadcasters to the alternative of DVB T2 leap frog
 Standardization of the set top box (STB):
 Basic STB (with basic TV Digital features), local content are minimum 20% and
to be increased gradually become 50% in the 5 years period.
 Must have the menu features in Bahasa Indonesia and features an early
warning of natural disasters and can be equipped with means of measurement
data services and television show ratings.
 Advanced STB (With the addition of several features such as an MHP, Early
warning system (EWS) for disaster, PVR, CA, etc).
 Preparation of existing broadcasters internally
