Diseño e implementación de un sistema de repro-ducción multimedia gestionable a través de la red basado en Linux para la Cooperativa de Ahorro y Crédito Fernando Daquilema agencias matriz y La Condamine.

Abstract

The present degree work implements a scalable system of low cost that allows the multimedia player manageable through a network to two agencies of the "Fernando Daquilema" Cooperative of saving and credits. For this purpose, the feasibility of its infrastructure was analyzed by veri-fying the traffic generated by submitting it to tests of the Hypertext Transfer Protocol (HTTP), the Secure Shell Protocol (SSH) and the Real Time Transport Protocol (RTP) concluding that the traffic in all three cases occupy 90% to 100% of the bandwidth with times depending on the file size or signal quality. The performance of the communications equipment remained stable at 3% and 58% of the Central Processing Unit (CPU) and memory respectively, with the exception of the RTP protocol that increased these values in the 2% and used more than 90% of the device's capacity. These results allowed to select the HTTP protocol as the most optimal discarding the SSH protocol due to the lack of software for its management. Finally, the implementation and configuration of the system was carried out installing the Raspbian-Strecht-Lite operating system and the Screenly-Ose complement for digital signaling on the Raspberry Pi. As a result, it was determined to work on the contingency link because it requires 100% of the bandwidth to the transfer of files without congestion. The system demands a 46% of the capacity of the device. After evaluating the results obtained in the tests, the project developed was scaled to the 12 agen-cies that the cooperative has at a national level with the same results. It is recommended to extend the compatibility with multimedia formats not currently supported, perform the grouping of de-vices for management in a single web interface and allow the reproduction of videos in real time without affecting the performance of the device.
