IPDC Talks 2018 @ Kuala Lumpur

The IPDC Talks is an initiative of UNESCO’s International Programme for the Development of Communication (IPDC). The IPDC the only intergovernmental forum within the UN system designed to mobilize the international community to discuss and promote media development and access to information around the world.

Asia-Pacific Institute for Broadcasting Development (AIBD)  collaborated with UNESCO and RTM to organize the IPDC Talks 2018 @ Kuala Lumpur with the theme - Benefits and Challenges of Access to Information in Malaysia. This event was held on 24th September 2018 at Auditorium P.Ramlee, Angkasapuri, Kuala Lumpur, in conjunction with the International Day for Universal Access to Information (IDUAI) which falls on 28 September each year.

IDUAI itself or the Right To Know Day has particular relevance with the Sustainable Development Goals (SDG) target 16.10 which calls for ensuring public access to information and protection of fundamental freedoms.

The IPDC Talks ha set three core objectives:

  • To show that public access to information and ICTs, along with strengthening media institutions that help assure access is key to achieving the SDGs in their totality.

  • To encourage Member States to consider integrating free, independent and pluralistic media, as well as universal access to information and knowledge via ICTs, within their policies for implementing SDGs in a creative, accessible and innovative way.

  • To raise public awareness about the media’s important role in monitoring progress towards the SDGs and in holding governments accountable for their achievement, and seek support to strengthen media development and access to information initiatives in this direction, particularly in LDCs.

Partnership with AIBD and RTM

In 2018, UNESCO is collaborating with the Asia-Pacific Institute for Broadcasting Development (AIBD) and the national broadcaster, RTM to produce the “IPDC Talks 2018 @Kuala Lumpur”. This is the first time that the IPDC Talks is taking place in Malaysia.

AIBD is an inter-governmental organization founded by UNESCO in 1977, servicing countries of the United Nations Economic and Social Commission for Asia and the Pacific (UN-ESCAP) in the field of electronic media development. It is hosted by the Government of Malaysia and the secretariat is located in Kuala Lumpur.

The AIBD is mandated to achieve a vibrant and cohesive electronic media environment in the Asia-Pacific region through policy and resource development.

 

About Access to Information

Access to Information (ATI) can be defined as the right to access information held by public bodies. It is an integral part of the fundamental right of freedom of expression, recognized by all international standards including the Universal Declaration of Human Rights (UDHR) (1948), which states that the fundamental right of freedom of expression encompasses the freedom to “to seek, receive and impart information and ideas through any media and regardless of frontiers”.

More recently, the Sustainable Development Goals (SDGs) adopted in 2015 also recognize that access to information held by public bodies is a necessary enabling mechanism for public engagement across the all the goals and was specifically incorporated into Goal 16 to “promote peaceful and inclusive societies for sustainable development, provide access to justice for all and build effective, accountable and inclusive institutions at all levels”.

It is well documented that having strong and effective access to information has been vital in the fight against corruption and abuse of power. Additionally, there have been success stories of rural communities using ATI to improve access to water, improving participation of the indigenous community, using ATI to gain access to quality education for children, and using ATI improve women’s access to health care.

Globally, the trend is more and more nations are adopting Access To Information laws. As of 2018, a total of 113 countries have adopted legislative measures on access to information. Ten years ago, just under 80 countries have ATI laws.

Key Speakers:

  • H.E. Mr. Steven Sim Chee Keong (Malaysia)

  • Ms. Kishali Pinto-Jayawardena (Sri Lanka)

  • Mr. Amos Toh (Singapore)

  • Dr. Azmi Sharom (Malaysia)

Digital broadcasting is a broadcast technology based on the transmission of audiovisual media information by bit streams. The most dynamic and technically complex environment of TV content distribution is digital terrestrial television broadcasting (DTTB). Traditionally, TV broadcasting served stationary receivers at home. Today’s users require information, infotainment and entertainment anywhere, at any time and on any device, if possible interactively and at the highest possible service quality. Modern broadcasting concepts try to cope with these demands that can only be satisfied by digital technologies. Therefore, transition from analogue to digital technology  is a must. Migrating to DTTB allows broadcasters to be competitive and more attractive than the other modes of delivery of TV services.  The transition process allows for a gradual introduction of Digital TV services without subjugating the existing analog TV viewers until such time when a prescribed percentage of the viewing population has already shifted to digital which will subsequently warrant the termination of analog broadcasting services. Considering that the migration to Digital Terrestrial Television Broadcasting has been a global trend, the Asia Pacific countries could learn from the experience and best practices of other countries’ migration to Digital TV. The development of a national roadmap for transition to digital terrestrial television starts with an analysis of the current TV market structure, analogue TV networks and regulatory framework. The aim or end milestones of the roadmap are identified by formulating the digital switch-over (DSO) objectives.

India has adopted DVB-T2 Standard for digitalization of its huge terrestrial network and progressing significantly towards implementing DVB-T2 and T2-Lite services in the country. Doordarshan India (DDI), the public Service Broadcaster   has one of the biggest Television network in the world with more than 1100 transmitters of different power levels and categorised as High Power Transmitters (HPT), Low Power Transmitters (LPT) and Very Low Power Transmitters (VLPT). DDI is in the process of digitalisation and aims to install 630 DTT transmitters finally having 230 HPTs and 400 LPTs for covering the whole country with a number multiplexes at every location to provide a bouquet of services to the viewers.  Therefore, it is very appropriate for other countries in the region to gain from the transition experience of India. Regional workshop on DTTB Transition Strategy conducted in New Delhi on 09.05.2018 as a pre-summit workshop during Asia Media Summit (AMS-2018) thus got relevance.
