• Analogue terrestrial TV has been around for
more than half a century beginning in 1927 inmore than half a century beginning in 1927 in
the USA (1964 in Afghanistan).
• As per the ITU’s (RRC-06) agreement all member
countries (including Afghanistan) are required
to switchover to DTV by June 2015.to switchover to DTV by June 2015.
• Post June 2015, ITU or any originating
country/entity is not responsible for any cross-
border interference with any existing Analogue

• In simple words, Digital Television (DTV) is a more
improved and efficient medium to broadcastimproved and efficient medium to broadcast
multimedia content compared to Analogue
• In Digital broadcasting (DTV) multi-media
content (Images, Sound, Text..) are transmitted
in a high quality compressed format allowing a
broad range of services/content to bebroad range of services/content to be
broadcasted and delivered in less space

Standards and Platforms
• Standards: The three most common standards
are DVB C (cable TV) DVB T (old version) DVBare DVB-C (cable TV), DVB-T (old version), DVB-
T2 (latest version). Afghanistan will most
probably go for DVB-T2.
• Platforms: There are four common service
provision and access Platforms:
1. Digital Terrestrial Television (DTT).
2 Digital Cable2. Digital Cable.
3. Digital Satellite (D-Sat).
