Nowadays in the audiovisual industry there are some solutions for deployments of video walls. There are those who only use video technology for deployment, there are others who have made a leap to IP technology. In many of these systems the first condition is to use a specific device such as a screen or a converter. The cost of these deployments is very expensive, especially for the specific of devices. There are products on the market with the same features that we propose in this thesis, although none of them allow a reusable environment, a low cost and a heterogeneous hardware level. Specifically, this thesis is focused in analyse, propose and develop an environment that use the IP protocol for the content's diffusion of content that we will reproduce in the screens. The main condition is not to use any specific hardware, achieving a deployment of an environment with a miscellany of equipment. The liveMediaStreamer framework will be used for transmission of the data streams. It will add a module of splitting in order to process the cuts and also the generation of new flows from a single one. We will find out solutions in order to achieve synchronicity between screens. A website platform will be made, capable of managing the whole environment. Having the liveMediaStreamer framework as a starting point, it has been simple to coupling the new module of splitting. A robust control web application for the videowall has been performed, which can allow the addition of some improvements in order to automate much more the platform. In order to achieve a stable and synchronous environment between different screens, many synchronization systems have been tested. A stable environment has been achieved thanks to forcing the playing time of all devices to the timestamp generated by the server for each frame and using the same receiver and the same software to reproduce the content.
