Haiti - Technology : Digital TV, technological change nationally
The purpose of this tour was to inform operators of television, viewers, state officials and the public in general of social, economic and cultural challenges of the transformation of the television landscape. CONATEL wants the transition to be inclusive, participatory and, therefore, a national success. To inform the nation of the planning and progress of the process, understand their concerns and receive at the same time his comments and suggestions on this great technological change, the communication team of the telecoms regulator travels the country.
Topics covered during this tour were Why Haiti embarked on the transition from analogue to digital TV? and How the Haitian State planning the transition to make it a national success?
Four presentations were made in these four cities, to more than a hundred Directors and representatives of TV stations and journalists of the press radio and television, was the target audience of this important activity.
After the introduction of Presenter Jean Claude D. Chery, economist and advisor communication, methodology and technical consolidation to the Office of the Directorate General of CONATEL, Mr. Rose Nesmy Saint Louis made the contextualization: technological change and transformation of the television landscape, an effort to better prepare the guests to master the material and the spirit of the two presentations. With simple words, he showed how and why it is essential to enter in it, to make the transition in an orderly, inclusive and participatory manner.
In the first presentation, the engineer Gregory Domond, Information Technology and Communication (ICT) specialist and member of the Technical Office of the Directorate General of CONATEL, made his presentation with as much method cohesion. Topic: the challenges and the planning of process of transition to digital television. Straight to the point, he stressed the need to see the abandonment of analogue system in favor of the digital system as the result of technological change. While specifying that the new reality will affect the radio after the TV, he highlighted the various aspects of this change, its benefits, its multisectoral nature, its technical implications, technological, economic and social. Also he developed on the methodology and guidelines used in planning for the transition, which focuses on six areas:
National ownership of the agenda of the transition: policy and regulatory framework, Communication: Awareness and promotion around the transition process, Infrastructural transition planning, info-structural planning (content and programs), economic evaluation and accompanying measures and post-transitional Management (digital dividend and monitoring of the evolution of the sector).
The speaker has provided many explanations and many details on the procedures, expectations, etc.. Without losing his breath, he approached the stage with many opportunely to the satisfaction of the owners / directors of Television of the region.
Both television system (analog and digital) were reviewed to better enable participants to understand the difference. Very technical, and with a warm tone, he explained the process of image transmission in both systems. For over an hour, he highlighted the evolution of television, "black and white" in color TV and now digital. In addition, he pointed out that the transition
Mr. Domond presented the network architecture of digital television and its main components: content production (television channel), transportation (fixed link between the studio and transmitter site), multiplexing (grouping several programs on the same channel) and broadcast (television signal propagation in a specified coverage area). The role of multiplexing new element of the architecture of the digital terrestrial television (DTT) was dissected because of the environment of the new landscape.
Unlike analogue TV environment, in which an operator manages the entire system, each component of the system - in the digital environment - can be operated by a different operator. This new situation requires a new mode of operation for operators and producers. For example, several programs may be disseminated through the multiplexing of a single antenna. Considering the capacity of a single signal for broadcasting several programs (TV channels), we can talk about a major change in the system of transmission of television signals. In such an environment, the program producer may not be the diffuser. Thus, faced with the new reality that is needed, multiplexing facilitates the sharing of broadcast infrastructure.
In the second presentation, hosted by the engineer Jean Claudy Balan, the second presentation was devoted exclusively to technical aspects of the transition.
At first, he talked the functioning of a television system - from components of the value chain of a television system, through the different standards and compatibility, to the evolution of systems audiovisual either the illustration of all the characteristics of a TV show. In a second time, Mr. Balan presented the preliminary plan for the deployment of digital TV while enumerating its various stages. He announced the recruitment by CONATEL of a specialized firm capable of providing the necessary technical assistance to the final deployment of digital television in Haiti. A workshop on the technical parameters of diffusion will be facilitated by the said firm to the intention of the
actors involved in the transition.
Following the two presentations, relevant questions were asked. Economist Rose Nesmy Saint Louis after each presentation, joined the engineer Jean Claudy Balan to provide supplementary answers and / or explanations. The responses were, according to the guests, "up to the expectations."
Recall that the transition from analog TV to digital TV is a requirement of the International Telecommunication Union (ITU), which sets the deadline to 17 June 2015, to complete the transition. However this transition was not imposed to Haiti.
