Implementation of a Real-Time Communication Library Between Smart TV Devices and Android Devices Based on WebSocket for the Development of Applications

Abstract

The smart device industry has grown in recent years, so the vast majority of people have a smart TV and at least one smartphone in their homes. The transformation of the digital era seeks to improve the user experience and facilitate the use of different smart devices. Due to this, it is proposed to develop a communication library that allows multiple Android devices to be connected to an LG WebOS Smart TV and thus promote the development of applications for Smart TVs, avoiding implementation from scratch and speeding up the deployment of new applications that generate great value for users. In this article, a comparison was made of the main communication protocols existing and compatible with the devices involved. During the development stage, the communication library based on the WebSocket protocol was implemented. Also, a retro videogame was implemented that used the communication library to connect the LG WebOS smart TV with the Android Smartphone. Finally, the results obtained and the opportunities for improvements found for the development of future applications will be shown.
