The objective of this project has been the design and implementation of a Digital Signage extension, which allows the visualization of the multimedia information of the articles present in the web pages of the Content Management System called Joomla! To do this, we studied the market offers and the different types of extensions present in Joomla, to decide on a Module. With regard to all this, a Module has been developed that allows, besides visualizing the images of the articles, to visualize the Author, the Title of the article and the first lines of the text, in a clear and beautiful way. To do this, we obtain the information of the articles in the form of a JSON file, which our module parses to data. Once this data is obtained, it creates a slide show formed by the images and the rest of the data. These slides are created dynamically according to the parameters that are introduced in the administration part of the module, allowing to choose between multiple options. They are automatically updated every certain time, configurable as well. From the configuration, we can choose which data, such as the title, author, text; and in what way we want to be shown on screen and which not. This project allows to visualize the information of any article in a clear way, with the data chosen in its wide configuration, so that it is a useful and easy to use tool.
