TVHD Montréal est une entreprise spécialisée dans l'installation d'antenne de réception de signaux de TVN (télévision numérique "en direct"). Voici ce que TVHD Montréal peut faire pour vous :
Tester votre antenne VHF / UHF actuelle (votre antenne permet-elle la réception des signaux numériques?);
Tester le potentiel de réception à partir de votre résidence (votre maison est-elle bien située pour capter les signaux numériques?);
Installer une antenne de télé (pour capter les nouveaux signaux numériques ainsi que les signaux analogiques);
Offrir un service de conseils à distance pour vous aider à prendre de bonnes décision et à économiser.
Vendre des équipements de réception de télé numérique HD (lors des tests et/ou installation ou suite à une consultation à distance).
Follow these instructions to build a top performing HDTV antenna for almost nothing!
This tool will analyze your location to determine which broadcast television signals are available in your area. It will compute the expected signal strength for every channel "in the air" at your location, including adjustments for transmitter power, terrain obstructions, curvature of the Earth, and other factors that affect signal availability. This information can help determine the relative signal strengths of stations that are potentially within reach of your location. It can also come in handy when trying to troubleshoot reception problems.
In order to begin the analysis, you must first enter a location.
At a minimum, you can simply enter a zip code. This will give you a rough idea of what TV transmitters are in your area. However, if you want a more accurate analysis, you should enter a more precise location. For privacy reasons, exact addresses and coordinates will be not be shown in the output.
The correct antenna will maximize your reception of free, over-the-air television channels from your local broadcasters.
With an antenna that is too weak, you may not receive all of the local channels available to you. An antenna that is too powerful may lead to poor reception on some channels due to interference from distant stations.
AntennaWeb.org is co-sponsored by the Consumer Electronics Association (CEA), the preeminent trade association promoting growth of the U.S. consumer electronics industry, and the National Association of Broadcasters (NAB), the premier trade association for broadcasters, promoting and protecting the interests of local radio and television broadcasters nationwide.
Optimal television reception relies on a clear line-of-sight between your location and a station's tower. Typically, the closer you live to the tower, the better the reception of its signals. However, many variables, such as distance, terrain or nearby structures, may impact which antenna you will need to receive those signals.
To simplify choosing the correct outdoor antenna, the CEA and the NAB have created a color-coded labeling standard for classifying antennas by type. Antennas labeled for a particular type will share common reception capabilities and directional qualities, regardless of manufacturer.
AntennaWeb.org is designed to take the guesswork out of choosing the correct outdoor antenna type for your location and your viewing needs. Once you have determined the proper antenna type, visit your retailer to select the desired antenna within that color-coded type according to your personal preferences about features, price, manufacturer, etc.
Create maps, analyze your data and develop your location aware applications with ease.
MapBox builds tools for publishing fast and beautiful interactive maps for web and mobile devices.
Our customizable worldwide steet-level map MapBox Streets, our high-performance cloud publishing platform and our open source map design studio TileMill make it easy for anyone to create beautiful custom maps.
High Road is a framework for normalizing the rendering of highways from OSM data, a critical piece of every OSM-based road map we’ve ever designed at Stamen. Deciding exactly which kinds of roads appear at each zoom level can really be done just once, and ideally shouldn’t be part of a lengthy database query in your stylesheet. In Cascadenik and regular Mapnik’s XML-based layer definitions, long queries balloon the size of a style until it’s impossible to scan quickly. In Carto’s JSON-based layer definitions the multiline-formatting of a complex query is completely out of the question. Further, each system has its own preferred way of helping you handle road casings.
We’re proud to give you a sneak peak of Carto, one of the components of TileMill, our upcoming full-featured map design studio that lets you rapidly design completely custom maps. Carto is a CSS-like map styling language based on less.js. This gets us all the syntactic goodies such as nested styles and named variables.
Web Maps Studio is a suite of tools that gives web developers everything they need to create customized, interactive map based web apps. Full integration with Style Editor, Data Market place and CloudMade’s other geo services means that developing feature-rich web app has never been easier.
TileMill is an application for making beautiful maps. Whether you're a journalist, web designer, researcher, or seasoned cartographer, TileMill is the design studio you need to create compelling, interactive maps.
