Implementation of technology in the Nepali market is growing gradually. We are now no less behind to access to the latest technology followed by the customers of the developed countries. For instance, in the case of television transmission technology, most of the users had to rely on the analogy technology provided by the cable operators. The service and quality of was at the worst stage and people were interested towards illegal Indian DTH. Then gradually after the initiative of government, DTH service has established itself in the market. As the accessibility of the service, the company was able to expand itself to rural areas. And recently with further development, there is also the service of IPTV, as result of growing use of internet and increase in the speed of the internet.
Well, before that some decades ago we had access to limited channels through terrestrial transmission where we had to adjust the antenna to watch limited TV channels. Now the same technology has advanced to the second generation known as Digital Terrestrial Television (DTT) as a result a new company Prabhu TV under Prabhu group is gearing to start service under same technology.
DTT is Digital Video Broadcasting-Second Generation Terrestrial (DVB-T2)
DTT is Digital Video Broadcasting-Second Generation Terrestrial (DVB-T2). This system transmits compressed digital audio, video, and other data in “physical layer pipes” (PLPs), using OFDM modulation with concatenated channel coding and interleaving. The higher offered bit rate, with respect to its predecessor DVB-T, makes it a system suited for carrying HDTV signals on the terrestrial TV channel (though many broadcasters still use plain DVB-T for this purpose).
According to the company, they have completed all the government procedure to achieve the license and have been allocated required bandwidth to operate service. The company has also completed test transmission and is planning to launch within a month. The company is planning an aggressive price for the service to compete directly with the existing DTH provider. Though, the company has not yet fixed the number of channels and price.
The company said that “there no need of additional antenna or cable to be connected to access the service directly through the device provided by the company. The company claims the device is capable of receiving signal in 90 percent of the area and 90 percent of the channel without the antenna. On the first phase, the company is planning to launch the Prabhu TV service in Kathmandu, Pokhara, and Chitwan.
Here’s the Basic Difference between DTH and DTT
DTH – Direct to Home
- Broadcast via satellite
- Ku, Ka or C-Band transmission frequencies
- Phase modulation (QPSK or 8PSK)
- A wide range of RF bandwidth options
- National, continental or even hemispherical coverage from a single transmission
DTT – Digital Terrestrial Television
- Broadcast from ground-based antennas usually built on masts
- VHF or UHF frequencies
- COFDM modulation
- Fixed RF bandwidth (6, 7 or 8MHz depending on the country/region)
- Local coverage (10’s to 100’s of km’s)
