Recently, there have been increasing interests to characterize the UHF wideband mobile reception. In the literature, there are several studies on UHF mobile reception for cellular phone systems, however, most of them addresses narrowband services. This paper presents propagation measurement results on UHF TV band using the ATSC Digital Television as a sounding signal to study the characteristic...

Television has traditionally been a passive medium from the viewerÕs perspective. The viewer sits in front of the television receiver and passively absorbs what is presented. On the other hand immersive virtual reality systems engage the user and bring the user into the virtual world, often as a participant rather than just as an observer. This paper looks at applying virtual reality display te...

We demonstrate the ability to receive live color analog television and video game signals with use of Rydberg atom receiver. The typical signal expected for traditional 480i National Television Standards Committee format requires a bandwidth over 3 MHz. determine beam sizes, powers, detection method required atoms this type signal. size affects average time remain in interaction volume, which i...

Future cable television (CATV) and satellite-television receiver systems require the development of wideband power dividers (PDs) covering a few megahertz to gigahertz. Conventional PDs designed using either distributed circuits or lumped elements cannot accomplish this purpose. In paper, novel ultrawideband PD is developed with combined design both transmission line Wilkinson divider (WPD) com...

Digital Video Broadcasting-Terrestrial (DVB-T) is an international standard for digital television services. Orthogonal Frequency Division Multiplexing (OFDM) is the core of this technology. OFDM based system like DVB-T can handle multipath fading and hence it can minimize Inter Symbol Interference (ISI). DVB-T has some limitations too namely large dynamic range of the signals and sensitivity t...

This paper shows a grid computing architecture called Grid Anywhere which aims at allowing the sharing of the computational resources from set-top boxes (receiver) of an Interactive Digital Television System. This sharing is made in a such a way that the TV broadcaster can use the set-top boxes tuned to it to get a high computational power and the user can also use remote resource of others dev...

c able television (CATV) was known originally as "community antenna television." Today it represents the broad area of entertainment and other services carried over coaxial cable networks to various subscribers, As implied by the name, the original purpose of CATV was to serve communities with entertainment television service where TV reception was poor, The idea was to find one good receiving ...
