Nicolas.

Si desde el STB queres acceder a una URL para consumir datos o para enviar
datos por parametros en la URL, necesitas el canal de retorno.

Se llama canal de retorno no porque retorne algo, sino que nos dá la
posibilidad de usar ese canal para completar la interactividad en la
aplicación y retroalimentarse si se desea.

Una aplicación práctica seria por ejemplo contestar una encuesta de
satisfacción sobre el uso de la notebook, es un concepto sencillo.

Saludos, Marcelo
