This new technology, in addition to providing a high quality audio and video, also allows applications to execute on television. Equipment called Set-Top Box are needed to allow the reception of this new signal and create the appropriate environment necessary to execute applications. At first, the only way to interact with these applications is given by remote control. However, the remote control has serious usability problems when used to interact with some types of applications. This research suggests a software resources implementation capable to create a environment that allows a smartphone to interact with applications. Besides this implementation, is performed a comparative study between use remote controle and smartphones to interact with applications of digital television, taking into account parameters related to usability. After analysis of data collected by the comparative study is possible to identify which device provides an interactive experience more interesting for users === O Brasil atualmente passa pelo processo da transi??o da transmiss?o anal?gica para a transmiss?o digital. Essa nova tecnologia, al?m de disponibilizar uma qualidade alt?ssima de ?udio e v?deo, tamb?m possibilita a execu??o de aplicativos na televis?o. Equipamentos chamados conversores digitais s?o necess?rios para permitir a recep??o desse novo sinal al?m de criar o ambiente apropriado necess?rio para a execu??o desses aplicativos. A princ?pio a ?nica forma de interagir com esses aplicativos se d? por meio do controle remoto. Entretanto, o controle remoto apresenta graves problemas de usabilidade ao ser utilizado em alguns tipos de aplica??es. A partir desse problema, esse trabalho prop?e a implementa??o de recursos de software capazes de permitir que essa intera??o possa ser realizada com a ajuda de smartphones. Al?m dessa implementa??o, ? realizado um estudo comparativo entre o uso do controle remoto e do smartphone para promover intera??o com as aplica??es da televis?o digital, levando em considera??o par?metros relacionados ? usabilidade. Ap?s a an?lise dos dados coletados por essa compara??o ? poss?vel identificar qual dispositivo possibilita uma experi?ncia interativa mais interessante aos usu?rios
