This paper presents an analysis of digital television broadcasting, that used DVB-T2 standard, in Bangkok Thailand. The result of analysis has derived from signal measurement 20 location in Bangkok. The measurement location consists of several difference areas such as an urban area, high building area, open area. The measurement’s result are consists of signal strength, C/N, MER, SNR, NsMAR, bBER, LBER, power output after combiner. The measurement illustrates the effect of attenuation and interference in propagation channel.

Digital Video Broadcasting-Terrestrial (DVB-T) is the most widely deployed digital terrestrial television system worldwide with services on air in over thirty countries. In order to increase its spectral efficiency and to enable new services the DVB consortium has developed a new standard named DVB-T2. A nearly definitive specification has already been published as a BlueBook as well as an implementation guideline, where the structure and main technical novelties of the standard have been defined.

The role of the television has huge impact on the 21st century and basically the televisions either make use of SFN single frequency networks (SFN) or multi frequency networks (MFN) and both these networks are ideal for meeting the practical requirements either in local and global services. Another important drawback in these two networks are these two networks consumes huge amount of spectrum.

The allocation of frequencies traditionally used by terrestrial broadcasting (digital dividend) to International Mobile Telecommunication (IMT) is limiting the evolution of the Digital Terrestrial Television (DTT) networks for enhanced service offering. Next-generation DTT standards are called to provide increased capacity within the reduced spectrum. Time Frequency Slicing (TFS) has been proposed as one of the key technologies for the future DTT networks.

This paper analyzes potential DVB-T2 transmission modes to optimize existing DTT network designs of Colombia, originally made for DVB-T, analyzing the trade-offs between capacity, coverage level and Single Frequency Network (SFN) size. Network planning results has been performed with a professional DTT network planning tool based on the three first deployment phases of the DTT network of the public national TV broadcaster RTVC. Results obtained fully justify the decision of adopting DVB-T2. Compared with the initial DVB-T design, DVB-T2 can increase the national covered population up to 7.

Reports of the death of TV have been greatly exaggerated. Contrary to predictions that the digital age would drag people away from TV, we are watching more TV than ever. Rather than being eroded, people’s viewing experience is being enriched by social networks and dedicated social TV apps like Zeebox. Increasingly, the assumption that a laptop, and a tablet or mobile are the 'second' and 'third' screens will dissipate. It will not be enough to simply broadcast a hashtag and flag a few tweets on the television screen.

Satellites have already been accepted as an effective medium for the communication of education and health services. For example, The Rural Health Education Foundation of Australia broadcasts distance education programs using digital satellite technology, the Internet including live webcasting, “enduring” materials (DVDs), other television services and new technologies as they become available. The Foundation operates a continually expanding network of more than 660 satellite receiving sites throughout rural and remote Australia, called the Rural Health Satellite Network.

PUBLIC SATELLITE NETWORKS Satellites have been carrying communications since the early 1960s, serving as relays for voice, video, or data. They have long been dominated by the military and, in their direct broadcast form, by large television communications companies. In 1989 the Gartner Group believed that “the mobile satellite industry will be one of the great growth markets of the next decade—surpassing cellular telephones and digital paging, and in the same league as personal computers.
