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 channelsSo many local broadcasters! So many program channels! More difficult to allocate the available frequency channelsto deploy DTV services

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

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...)
