[EN] In this paper, a scalable hardware and software architecture for low-cost tiled display systems (a.k.a. videowalls), customizable through a dynamic web-based management and configuration service is presented and evaluated both objectively and subjectively. It has been designed for both stored and live broadcast/broadband content, in mosaic or warp distributions. The videowalls can be dynamically configured via web in different ways: the displays can create a single screen of a larger size, or they can be configured in a customized way in order to playout different media contents in different display combinations. As display renderers, low-cost devices are proposed as the main hardware element to obtain affordable videowall systems. As a proof of concept, two prototypes have been implemented, including an accurate synchronization mechanism. To evidence the good performance of the prototypes and configuration service, Both objective and subjective evaluations have been conducted regarding synchronization accuracy and usability of the configuration service, obtaining satisfactory results., This work has been funded by the Generalitat Valenciana, through the R&D Program "Grants for research groups to be consolidated, AICO/2017" under Project AICO/2017/059.

En aquest projecte es du a terme el disseny i la creació d'una aplicació per al sistema operatiu mòbil Android (desenvolupat amb XML, Java i C/C ++) amb la qual es poden visualitzar estructures tridimensionals de molècules com proteïnes i àcids nucleics en el format de Protein Data Bank (PDB). El treball també inclou una interfície gràfica d'usuari, adaptat a la tecnologia tàctil que proporcionen els dispositius mòbils intel·ligents actuals basats en el sistema operatiu Android, que permet la interacció amb l'usuari.
