The prohibitive cost and size of traditional television tuners are preventing the spread of television to poorer areas and mobile applications. Fully integrated television tuners could reduce the size and cost but currently face issues with noise and linearity which are both strongly dependant on the corresponding specifications of the lownoise amplifier (LNA). Noise and linearity face a trade-...

According to the rapid development of the digital technology, the broadcasting environments are changing into the digital television transmission including the ATSC, ISDB-T, Digital Video Broadcasting – Terrestrial (DVB-T), etc of the high quality and high-efficiency from the existing analog television transmission. In the transition to digital broadcasting, the methods that can efficiently use...

Holographic television, or “holo-video,” has been seen by many as the ultimate development not only of holography but of electronic visual communication generally. To make widespread, successful holo-video, four things are needed: 1) content, 2) a distribution mechanism, 3) sufficient processing at the receiver, and 4) suitable electro-optics at the display, and all of these must be available a...

The study and development of systems for higher quality television has seen tremendous growth in recent years. This has been motivated by the fact that existing television systems give inadequate picture quality, especially for viewing on large screen displays. The main impairments which have been identified an~ scanning artifacts (line stucture visibility and flicker), limited resolution, and ...

This paper presents a compatibility study between future digital television (DTV) and Long Term Evolution (LTE) in the UHF band using Nigeria as a case study. This is done by carrying out an adjacent interference analysis to evaluate the impact of LTE base station on DVB-T2 reception using SEAMCAT software. Results obtained from simulations suggest that deploying LTE in an adjacent band would r...

Digital terrestrial television services using the DVB-T standard will be launched later this year in the UK, followed by Sweden and perhaps other countries soon afterwards. Reception of these services will make use of domestic set-top boxes and integrated receivers using DVB-T demodulator ICs (integrated circuits). The first of these ICs are now becoming available, and it is important that thei...

The evolution of the geographic distribution of producers in the television receiver and automobile industries is analyzed. Both industries experienced sharp shakeouts and evolved to be oligopolies, suggestive of increasing returns. The television receiver industry was initially concentrated regionally but evolved to be more dispersed over time. In contrast, the automobile industry was disperse...

This paper proposes a video-surveillance system based on a mobile-camera. In particular the developed system creates (during the off-line phase) a panoramic multilayer background image allowing one to use common change detection algorithms to search for a change detection binary image. Different approaches to get the change detection images are presented. Performances of the implemented algorit...

Recently, many multi-receiver signcryption schemes have been proposed. However, few schemes can send multimessages to multi-receivers, which is an important requirement for the cable television (CATV) networks. In this paper, to cope with the above problem, we present a multi-message and multi-receiver hybrid signcryption scheme based on the assumptions of a discrete logarithm and Gap Diffie He...
