Spectrum arrangement for DTV
The Digital Dividend
Summary
Overview on Viet Nam TV broadcasting
Viet Nam has 66 TV broadcasters:
- 3 nationwide TV broadcasters
- 63 local TV broadcasters
- 109 TV free-to-air program channels
So many local broadcasters! So many program channels!
More difficult to allocate the available frequency channels
to deploy DTV services
Overview on Viet Nam TV broadcasting
Market share of platform
CATV 1.56%
Analog terrestrial TV 76.5%
Digital terrestrial TV 12.5%
Sattelite DTH
TV digitization in Viet Nam
1. Benefits of TV digitization for Broadcasters
- Better quality of video and audio
- More channels, more services (Mobile reception,
mobileTV, HDTV, interactivity, data services)
- Local TV broadcasters may have larger service coverage
- DTV transmitter’s ERP requirement is lower
- DTV gives a chance to set up SFN
TV digitization in Viet Nam
2. Benefits of TV digitization for telecommunications
- Spectrum efficiency is high
- Digital Dividend. That is a big chance to deploy more
radio broadband services;
- The more Broadband services, the more multimedia
provided (such as Live TV channels, Interactive TV,
Time-shifted TV, Video on demand...)

TV digitization in Viet Nam
-
DVB-T standard have been adopted by VTV since 2001
VTC had launched DVB-T test project since 2002
2005 DVB-T was adopted to deploy nationwide
Planning on radio television broadcasting transmission
to 2020 was adopted by Prime Minister in 2009;
Drafted Digitization Project on terrestrial TV was
submitted to Prime Minister for approval
Radio law and Telecommunications law
TV digitization in Viet Nam
Drafted Digitization Project on terrestrial:
The final target of DTV roadmap: 95% of
population served by digital TV.
Transmission standard: DVB-T and its next
versions;
Compression standard: MPEG-2, MPEG-4 part
10/ H.264 (after 2014: MPEG-4 part 10 /H.264 is
mandatory)
Analog switch off has been scheduled from 2015
to the end of 2020 (region by region)

TV digitization in Viet Nam
* Terrestrial DTV
-
-
-
VTC has launched DTV services since 2006,
+2 MUX using MPEG-2 compression standard,
+ more than 20 TV program channels;
AVG has a trial of DTV SFNs with 3 MUX using MPEG4 compression standard in Ha Noi and Ho Chi Minh
City;
More than 2 million set-top-box have been sold out
to market
TV digitalization in Viet Nam
* Mobile TV
-
DVB-H was tested by VTC corporation in 2006,
T-DMB trial project has been broadcasted by VTV
in Ha Noi and Ho Chi Minh city
* DTH
-
VTV launched DTH using DVB-S standard since 2004
VTC launched DTH using DVB-S2 standard since 2009
Spectrum arrangement for
terrestrial TV
1. Multiplex and network planning
- 3 nationwide broadcasting transmission operators
with 7 DTV Multiplexes
- 5 – 7 DTV MUX for existing local ATV (multiplex by
regional areas)
Spectrum arrangement for
terrestrial TV
2. Frequency channel allotment for DTV
- to broadcast 2 MUX for VTV and 2 MUX for VTC with
nationwide coverage using MFN;
- to broadcast 3 MUX for third nationwide operator
using SFN providing Pay TV services;
- to broadcast 1 MUX for each regional networks
delivering existing local TV channels
Spectrum arrangement for
terrestrial TV
3. Frequency bands
- VHF band III: 174 – 230 MHz
- UHF band:
 Before 12/2009 : 470 – 806 MHz
 After 12/2009: 470 – 790 MHz
4. Draft of VHF band plan
- To be planned for DTV, Digital radio, Mobile TV
- Band III VHF (174-206) MHz for DVB-T/T-DMB
- Band III VHF (206-230) MHz for T-DMB/T-DAB
Spectrum arrangement for
terrestrial TV
5. Draft of UHF band plan
- Mainly for DTV implementation
- UHF (470-694 MHz) for DTV Long-term usage
- UHF (694-790 MHz) for DTV/ATV temporary
usage and to be freed up to develop other radio
services (Digital Dividend)
- After 12/2020 UHF band 694 – 790 MHz is going
to be freed up to launch other radio broadband
services
