Adaptive gap filler for digital terrestrial television

2014 IEEE International Symposium on Broadband Multimedia Systems and Broadcasting, 2014
This paper presents the development of an adaptive gap filler for Digital Terrestrial Television broadcasting. Unlike conventional equipment, which only amplifies and retransmits the desired signal, the proposed system employs cognition principles to analyze the adjacent channels spectrum, thus ensuring the required protection ratio.

Certified e-mail over digital terrestrial television

2007 15th International Conference on Software, Telecommunications and Computer Networks, 2007
Electronic mail service, better known as e-mail, is probably the most widespread asynchronous way of exchanging data among people, thanks to its immediacy and easiness of use. In the framework of e-mail services, ensuring a valid identity has become a vital step in stopping spam, fraud and even more serious crimes; to this aim, Certified e-mail (CE ...

Digital Terrestrial Television according to ISDB-T

2004
The Japanese standard for digital terrestrial television is called ISDB-T, i.e. Integrated Services Digital Broadcasting – Terrestrial, which was adopted in 1999, quite a long time after DVB-T and ATSC. This delay made it possible to take into account also the experience gained with the older standards.

Implementing a national federal digital terrestrial television network

International Broadcasting Conference (IBC), 1997
The UK government has passed legislation which provides for the operation of national digital terrestrial television broadcasting (DTTV). Within the present frequency planning system up to six multiplexes across most of the UK could be introduced. The target is to release the UHF spectrum from the occupancy by PAL analogue services so that it could be ...

Personalcasting: The way for the Digital Terrestrial Television's digital dividend

2009 Second International Conference on the Applications of Digital Information and Web Technologies, 2009
With Digital Terrestrial Television (DTT) it is possible to transmit different digital contents together with the video signal, i.e. datacasting. This has become possible due to the coding and compression technologies used to process the signal, not available with analogue technology.

Multimedia broadcasting using digital television terrestrial transmission systems

The 5th International Symposium on Wireless Personal Multimedia Communications, 2003
We describe how the transmission technologies developed for over-the-air digital television broadcasting, could be used to offer wireless personal multimedia communications. The results of some transmission tests demonstrate some of the potentials and problems of this approach.

Interference Simulation from LTE to Digital Terrestrial Television

2011 7th International Conference on Wireless Communications, Networking and Mobile Computing, 2011
In this paper, simulation is conducted to study the interference to digital television (DTV) system due to the introduction of Long Term Evolution (LTE) system. Access coverage loss curves and capacity performance of DTV system are plotted with Adjacent Channel Interference Ratio (ACIR).
