V. S SO BASICALLY THROUGH ALL THE THINGS SO MAYBE WE SHOULD THINK OF YEAH YEAH SO YOU CAN JUST GO ON THE STREET AND THEN SWITCH OFF EVERYONE'S T. V. AND YOU CAN JUST WALK AWAY YOU DON'T HAVE TO BE NEAR THE T. V. AT ALL MAYBE MAYBE WE CAN GO TO TO YOUR PRESENTATION UH MATTHEW I I I ASSUME YOU WERE FINISHED HERE UH OKAY SO I CAN TAKE I THINK MINE NOW THERE OKAY SO VOILA HMM I CAN TAKE MINE IT'S OKAY VOILA MM SO MM OKAY OH I UH SORRY I KNOW WHERE IT IS IT'S ON THE DESKTOP IT'S UH YES IT'S UH LIKE SO WELL SO UM I'M GOING TO TALK A LITTLE BIT ABOUT THE TECHNICAL FUNCTION SO WHA WHAT ACTUALLY IT'S ABOUT WHAT IS THE USER GOING TO DO I THINK MY LAST PRESENTED WHAT IS GOING INSIDE SO WHAT'S THE USER IS GOING TO SEE FROM THE OUTSIDE AND HOW HE IS GOING TO USE IT SO WELL THE APPROACH IS THAT UH BASICALLY THE IDEA IS TO SEND A MESSAGE TO THE T. V. SET AS MAEL HAS POINTED AND IT WILL BE DECODED BY THE T. V. AND USUALLY WE IT IS EASIER TO HAVE UH KEYS OR BUTTONS WITH WHICH PEOPLE CAN UH PRESS AND THEN UM CHANGING A BUTTON WILL BASICALLY UH CHANGE THE MESSAGE WHICH IS BEING SENT TO THE T. V. AND UH UM A AND BASICALLY IT SENDS AN INTERNAL SIGNAL AND DECODED BY THE RECEIVER SO P AS UM ANNA HAS SAID THAT THIS KI PEOPLE ARE INTERESTED IN THINGS WHICH ARE YOU DON'T NEED TO K PRESS THE KEYS
