Silent television: S_TV

摘要

This paper presents a solution that allows the users of a certain place to hear the sound of a TV, even if they are in a noisy environment. This gives the users a more efficient way to hear the sound of televisions in places where the volume of noise is high. The solution, named "s_TV" comprises two modules: the transmitter and the receiver. The transmitter module is composed by equipment to capture and transmit sound from the TV to smartphones/tablets Android. This equipment is connected to the TV and a router and transmits the sound through a network to Android devices. It can also transmit other types of information, such as the TV settings. An application was also developed to allow the configuration and handling of the servers that emit the sound of televisions. The receiver module resulted in a mobile application that allows the user to choose in a very simple and intuitive way, a particular TV channel and, subsequently, receive and play the sound on the mobile device, in real time. In addition, other features are available such as recording the sound played and sharing it on social networks. The tests conducted indicate that the solution may also be used in real-world scenarios with a scalable number of users, without compromising the services available on existing Wi-Fi networks.
