Diseño e implementación de la etapa de comunicaciones para transmisión de señal VGA entregada por un MSV utilizando un dispositivo embebido SoC FPGA

Abstract

Vital signs measuring medical devices have video outputs (DVI, HDMI, VGA), some without network interface; Those that allow Ethernet connection use their own proprietary transmission protocol. The purpose of this master's project is to contribute to the construction of a hardware and software solution that makes it possible to acquire the video signal delivered by the vital signs meter and to be able to transmit the signal to remote places to be consulted By medical personnel. In particular, this project offers the design and implementation of the communication stage of the device by means of modules that allow coding, compression and transmission via the secure Internet channel of the video delivered by the vital signs measurer. The Embedded Operating System used is Debian 8.0 Distribution for ARM architecture, the encoding task was performed with the FFmpeg package compiled for the ARM architecture. The FFmpeg package performs coding, transcoding and streaming tasks using the H.264 and libav-tools libraries. The coding and transmission phase worked correctly, being tested with different codecs, such as MPEG2, MPEG4, VP8 and H.264.
