INTRODUCTION

• Paraphrasing the start of the Gospel of ST JOHN,
  I would say
• ltlt In the beginning was the COMMUNICATION,
  and the communication was based on the
  SERVICESgtgt.
• The first Service was the LANGUAGE
• The second
  HIEROGLYPHIC
• The third
  WRITING
• All of these Services are INTERACTIVE in due
  time.

INTRODUCTION

• Historically, the use of Electromagnetic
  - Waves for Telecommunication, has originated
  the following Services
• Telegraph / Data
• Telephone
• Broadcasting (Sound and Television)
• The new technical developments (e.g.
  digitalisation) and the new techniques lead to
  the Convergence, and I can say that
• INTERACTIVITY is daughter of
  CONVERGENCE

DEFINITIONS
ITU-R Study Group 6

• R R ARTICLE S1
• Telecommunication
• Any transmission, emission or reception
  of signs, signals, writing, images and sounds or
  intelligence of any nature by wire, radio,
  optical or other electromagnetic systems.
• Radiocommunication Service
• A service as defined in RR involving the
  transmission, emission and/or reception of radio
  waves for specific telecommunication purposes.

6
DEFINITIONS
ITU-R Study Group 6

• Fixed Service A radiocommunication service
  between specified fixed points.
• Mobile Service A radiocommunication service
  between mobile and land stations, or between
  mobile stations.(CV)
• Broadcasting Service A radiocommunication
  service in which the transmissions are intended
  for direct reception by the general public. This
  service may include sound transmissions,
  television transmissions or other types of
  transmission.(CS)

DEFINITIONS
ITU-R Study Group 6

• Scope of Study Group 6 Broadcasting Services
  - (agreed by RA 2000)-
• Radiocommunication broadcasting (terrestrial and
  satellite), including vision, sound, multimedia
  and data services principally intended for
  delivery to general public.
• Broadcasting make use of point-to-everywhere
  information delivery widely available consumer
  receivers. When return channel capacity is
  required ( e.g. for access control,
  interactivity, etc.) broadcasting typically use
  an asymmetrical distribution infrastructure that
  allows high capacity return delivery link to the
  service provider. The production and distribution
  of programs (vision, sound, multimedia, data
  etc.) may employ contribution circuits among
  studios, information gathering circuits (ENG,
  SNG, etc.), primary distribution to delivery
  nodes,and secondary distribution to consumers.
• The Study Group, recognizing that
  radiocommunication broadcasting extends from the
  production of programs to their delivery to
  general public, as detailed above, studies those
  aspects related to production and
  radiocommunication, including the international
  exchange of programs as well as the overall
  quality of service.
