UH FIRST IS REMOTE CONTROL HAVE SH HA SHOULD HAVE SOME ELECTRIC CIRCUITS UH MAKING INTERFACE WITH UH KEYBOARD AND UH R READING UH KEYBOARD AND READING THE KEYBOARD UH COMMANDS AND THEN INTER THEN MAKE UH THESE KEYBOARD COMMANDS UH IN INTERPRET THESE INT UH KEYBOARD COMMANDS AND THEN THERE SHOULD BE UH AN ELECTRONIC CIRCUIT MAKING UH ELECTRONIC SIGNALS ACCORDING TO THESE COMMANDS AND UH FINALLY THERE IS A TRANSMITTER WHICH IS A CORD OR A A DIODE MAKING UH MAKING UH WAVES TO TRANSMIT THROUGH THE AIR AND UH UH THIS AIR THIS UH WAVE UH WILL BE RECEIVED BY THE BY THE OTHER DEVICE LIKE A TELEVISION OR WHATEVER TO UH R TO REALISE THE COMMAND OKAY UH ABOUT WHAT I FOUND ABOUT UH DIFFERENT UH THESE DIFFERENT BLOCKS ARE UH USUALLY THERE ARE TWO DIFFERENT METHODS UH TO FOR DESIGNING A REMOTE CONTROL THEY ARE BASED ON INFRA RED UH WAVES OR UH UH RADIO WAVES THERE ARE TWO DIFFERENT UH UH SOLUTIONS I MEAN THIS IS UH THIS CAN BE UH UH THE THE DIFFERENCES THE TH BETWEEN DIFFERENT KIND OF WAVES INFRA RED OR RADIO WAVES AND UH ALSO AS UH I UNDERSTOOD AND UH I THINK IT WAS A PART OF UH BOB UH UH PRESENTATION PEOPLE PREFER TO HAVE UH TO HAVE UH THE REMOTE CONTROL WITH LESS BUTTON SO FOR THE ELECTRONIC PART WORKING AND INTERFACING WITH BUTTON WE SHOULD WE SHOULD TRY TO T TRY TO DESIGN A REMOTE CONTROL HAVING UH SOME SOME SIMPLER BUTTONS OR SOME ROLLING BUTTONS TO JUST TO JUST TO SEARCH BETWEEN DIFFERENT OPTIONS AND SHOWING O SOMETHING ON T. V. AND PUTTING LESS LESSER STUFF ON THE UH ON THE REMOTE CONTROL AND UH PERSONAL PREFERENCES UH UH UH UH CERTAINLY A REMOTE CONTROL WITH UH WORKING WITH RADIO WAVES IS UH PREFERRED BECAUSE UH YOU CAN PR YOU CAN TAKE IT IN ANY DIRECTION AND YOU DON'T NEED TO TUNE IT ANY WAY AND UH UH AGAIN USING BIGGER BUTTONS AND LESS NUMBER OF BUTTONS ARE ALSO PREFERRED AS I SEE OKAY THAT WAS MY PRESENTATION OKAY I HAVE A QUESTION UH-HUH DO YOU THINK RADIO WAVES UM WILL INTERFERE WITH OTHER APPLIANCES IN THE HOME UH I DON'T THINK SO BECAUSE UH WE CAN MAKE UH WE CA WE CAN MAKE THIS WAVE IN A SPECIFIC FREQUENCY SO THEY CAN BE IN A RANGE WHICH IS NOT INTER INTERFERING WITH THE WITH OTHER DEVICES INSIDE THE HOME SO CAN WE USE ANY ANY FREQUENCY WE HAVE THE RIGHT TO USE ANY FREQUENCY WE CAN WE CAN WE CAN TUNE OUR UH TRANSMITTER TO WORK IN THIS RANGE AND FOR THIS RANGE WE DON'T NEED TO ASK ANY PERMISSION OKAY AND WHAT HAPPEN WITH UH RADIO WAVES WHEN TWO NEIGHBOURS HAVE THE SAME HAVE OUR REMOTE CONTROL FOR EXAMPLE AND SO DO THEY HAVE THE SAME FREQUENCY OR UH FOR THIS I'M NOT UH I I DON'T KNOW THE SOLUTION BUT ONE SOLUTION CAN BE SOMETHING LIKE PUTTING UH P PASSWORD OR SOMETHING INSIDE THE WAVE SO THE ONLY YOUR T. V. CAN UNDERSTAND IT YEAH IDENTIFICATION CODE INSIDE THE SO IT'S UH KIND OF HANDSHAKING UH WHEN STARTING TO UH WHEN YOU START TO COMMUNICATE WITH THE YOUR T. V. THEN THEN IT'S LIKE AN HANDSHAKING PROTOCOL WITH YOUR YOUR REMOTE SO SO IF TWO TWO DEVICES ARE TRYING TO GO TO COMMUNICATE WITH THE T. V. SET THEN THE THE THE ONE WHICH HAS THE MORE ENERGY IN THE WAVE IS CHOSEN WELL IT CAN BE A PROBLEM SOMETIMES BUT MOST OF THE TIME IT WORKS OKAY OKAY A SPECIFIC UH REMOTE CONTROL HAS A SPECIFIC F IT'S WORTH TO BUY AND THEY HAVE THESE PROBLEMS SOLVED SO SO WE DON'T HAVE TO THINK ABOUT THESE OKAY SO MAYBE YOU CAN TALK ABOUT THE FUNCTION AND I HAVE ONLY A COUPLE OF THINGS BECAUSE I HAD I STRUGGLED A BIT WITH THE SOFTWARE THAT I'M SUPPOSED TO USE IN THIS UH UH IN THIS COMPANY I WAS USED TO USE LINUX BEFORE SO BUT I TRIED TO TRIED TO BREAK THROUGH THIS TOO I GUESS MM AH OKAY HOW TO MAKE IT BIG SLIDE SHOW SLIDE SHOW OKAY THANKS OKAY OH SO I WILL SPEAK ABOUT WORKING DESIGN THAT'S THE FIRST SLIDE UH WHAT UH I HAVE TO DO A LOOK AT WHAT THE OTHER COMPANY OKAY SO UH PRESENTLY I AM LOOKING WHAT IS POSSIBLE TO USE WHAT CIRCUITS TO USE AND STUFF LIKE THAT BECAUSE UH I DIDN'T WORK UH WITH THESE UH CIRCUITS SO FAR SO I HAVE TO LOOK WHAT WHAT IS A V A V AVAILABLE ON THE MARKET FOR FOR THE COMMUNICATION FOR THE I. R. CIRCUITS AND SO ON SO I'M CURRENTLY LOOKING WHAT IS AVAILABLE ON THE WEB AND UH I WANTED TO ASK YOU M MAYBE AFTERWARDS AFTER AFTER OUR DISCUSSION IF WE HAVE SOME CONTACTS IN SOME COMPANIES SO WHICH CAN REPORT ON WHAT IS GOING ON THERE SO I WOULD BE GLAD IF YOU CAN TELL ME ABOUT THEM SO YOU KNOW UH OKAY FINDINGS THAT'S THE POINT THAT I'M WORKING ON CURRENTLY BUT UH SO FAR I I WAS UH LOOKING WHAT WHAT ARE THE BLUE CIRCUIT I MEAN RADIO WAVE RADIO FREQUENCY CIRCUITS ARE AVAILABLE NOW BUT THE PRICES I READ ARE HIGH SO I KNOW THAT UH THE USER INTERFACE PEOPLE AND THESE SPEAK ABOUT RADIO FREQUENCY WAVES BECAUSE YOU CAN YOU CAN UH YOU CAN MAKE THE T. V. DO WHAT YOU WANT EVEN IF YOU ARE IN THE BATHROOM OR SO ON BUT YOU KNOW WHEN YOU ARE NOT CLOSE TO THE T. V. YOU PROBABLY WON'T NEED TO TO CHANGE THE PROGRAM AND SO ON AND SO I AM I AM VOTING FOR S TO STICK TO THE UM INFRA RED CONTROL INSTEAD OF R. W. BUT WE WILL DISCUSS IT LATER MAYBE UH COMPONENTS TO USE I'M NOT EXACTLY SURE WHAT I WILL USE FOR THE DESIGN OF THE CIRCUIT IT DEPENDS UH ON WHETHER WE WILL USE THE L. C. D. AND MAINLY THE SPEECH RECOGNITION BECAUSE THE SPEECH REC YEAH ARE WE UM ARE WE PLANNING TO TAKE AN OFF THE SHELF AN O. E. M. COMPONENT FOR THE RADIO WAVE CIRCUIT OR ARE WE PLANNING TO CONSTRUCT OUR OWN CIRCUIT BOARD THIS WE THIS WE BUY I THINK BECAUSE IT'S RATHER CHEAP NOWADAYS AND IT'S NOT WORTH TO CONSTRUCT OURSELVES EXACTLY BUT I'M NOT SURE ABOUT THE CIRCUIT WHICH IS RESPONSIBLE FOR SPEECH RECOGNITION THIS I PREFER THAT WE SHOULD MAKE OURSELVES OKAY BUT IT DEPENDS WHETHER WE TAKE A DECISION TO USE IT SAME THING IT'S FAIRLY EXPENSIVE TO USE THESE CIRCUITS SO SPEECH RECOGNITION WELL L. C. D. IT'S OKAY BECAUSE IT'S COMMON NOWADAYS TO USE L. C. D. SO I AGREE ON USING ANY KIND OF L. C. D. LESS BUTTONS GOOD FOR ME AS A AS A DESIGNER OF THE CIRCUIT BUT THE SPEECH RECOGNITION WE HAVE TO COMPARE WHETHER THE PRICE AND THE WHAT DOES IT OFFER YOU KNOW YEAH I'M OR IT WOULD BE MAYBE FEASIBLE
