SO THEY DEVELOP SOMETHING TO SYNCHRONIZE THESE TWO CARDS TOGETHER AND TH UH THIS IS SOMETHING WHICH IS IT'S MORE W WHICH IS CALL UH DIRECT SHOW UH WHICH ALLOWS YOU TO TO SYNCHRONIZE UH THESE TWO CARDS TOGETHER AND BUT OF COURSE YOU WANT THESE TWO STREAMS TO BE SYNCHRONIZE BUT YOU WANT ALSO THESE TWO STREAMS TO BE SYNCHRONIZED SO THEY HAVE A SYNCHRONIZATION BETWEEN TWO SLAVES WHICH IS DONE BY THE MASTER HERE WE JUST USE UH THE ET ETHERNET NETWORK TO SYNCHRONIZE UH THESE TWO UM THESE TWO DEVICE UM I JUST WRITE INTERNET SOMETHING LIKE THAT AND UH THEY DO ONLY AUDIO AND VIDEO UH THEY DON'T DO ANY SLIDE UM SLIDE ACQUISITION YEAH OKAY SO YVES ASKED FOR THE DIVA I WOULD LIKE JUST TO TALK NOW REGARDING UH THE THE FIRE FREE SMART MEETING ROOM AT IDIAP DO YOU HAVE ANY QUESTION OR UH WHAT YEAH TAPE FREE SORRY TAPE FREE SMART MEETING ROOM SO FOR THAT I SO LIKE THE DIVA PROJECT IS A TAPE FREE ALREADY SMART MEETING ROOM HUH IT'S A TAPE FREE BUT ALSO VIDEO UH AND THE ACQUISITION IS DONE IN RAW VIDEO SO THE FILE IS HUGE AND THEY REALLY NEED UH UM THEY HAVE A LONG POST PROCESSING TO CONVERT RAW FILE TO UH DIVX OR TO OUR OWN FILES OKAY BUT THIS CAN BE DONE AUTOMATICALLY RIGHT I MEAN IS THE OKAY UH SO I WILL WRITE AND THAT'S WHAT YOU THEY USE MORE OR LESS IN T. N. O. ALSO THEY DIDN'T HAVE UH TAPES BUT WITH DIFFERENT CARDS YEAH YEAH YEAH THEY HAD SOMETHING OKAY SO MAYBE FIRST I WILL JUST DESCRIBE THE MA THE SMART MEETING ROOM THAT WE HAVE AT IDIAP IN FACT WE HAVE UH ALSO A MASTER SLAVE ARCHITECTURE UM I CLEAN A LITTLE BIT WE HAVE THE MASTER P. C. WHICH TAKE KS UH WHICH TAKES CARE ABOUT THE AUDIO I CLEAN THAT AND WE HAVE THE SLAVE P. C. WHICH TAKE CARES ABOUT THE WHITE BOARD AND THE SLIDES NOW IF WE LOOK AT THE VIDEO IF WE LOOK AT THE VIDEO IN FACT UM YEAH MAYBE FIRST I SHOULD MENTION THAT BETWEEN THE MASTER AND THE SLAVE WE HAVE UM THE MM A SYNCHRONIZATION SIGNAL WHICH IS CALL TIME MIDI TIME CODE I JUST WRITE MIDI AND FOR THE VIDEO WE HAVE THE VIDEO INPUT HERE WE RE USE THE UM MIDI SIGNAL UH WITH UM TO INSERT THE TIME CODE ON EACH FRAME AND WE SAVE THAT TO D. V. RECORDER UH I I HAVE VIDEO OKAY UH WE KNOW THE PROBLEM OF THAT THAT UH THIS IS THAT AFTER EACH MEETING SOMEBODY HAS TO TAKE CARE ABOUT THE D. V. TAPES AND TO T CONVERT THEM INTO DIVX SO MY IDEA IS TO D DO SOMETHING LIKE THAT IS TO DEVELOP A S UM UM UH A VIDEO SLAVE MACHINE MAY I SAY SOMETHING LIKE THAT YEAH A VIDEO SLAVE MACHINE UH WHICH USE THE MIDI UM WHICH USE ALSO THE MIDI TIME CODE NO SORRY SORRY I'M DOING SOMETHING WRONG WE HAVE THE VIDEO HERE WE JUST HAVE THE TIME CODE INSERTER SO WE TAKE THAT SIGNAL HERE AND WE MOVE TO THIS UH MACHINE HERE WHICH IS IN FACT JUST UH THE I. V. C. VIDEO CARD THIS JUST AN ACQUISITION CARD AND WE COM AND WE S AND WE CONVERT FILE DIRECTLY TO DIVX AND UM SO WE WILL HAVE HERE VIDEO AND ALSO BECAUSE WE WANT TO CONTROL THAT MACHINE WE USE ALSO THE MIDI TIME CODE THE MIDI TIME CODE TO START AND TO STOP THE MACHINE THIS IS JUST SOMETHING UH THAT UH THIS JUST TO REMOVE THE D. V. RECORDINGS BUT UM YEAH JUST UH THIS JUST AN IMPROVEMENT OF THE SMART MEETING ROOM OKAY UH DO YOU HAVE ANY QUESTION UH REGARDING UH THAT YEAH SO CURRENTLY BECAUSE THERE IS A TIME CODE UH VIDEO TIME CODE YOU DON'T CARE ABOUT THE FRAME DROPPING I MEAN BECAUSE ANYWAY IN EACH IN THE VIDEO SIGNAL IT IS ENCODED THE TIME RIGHT YEAH WE DON'T HAVE TO CARE ABOUT THE SYNCHRONIZATION IN THAT CASE BECAUSE THE TIME CODE IS INS SERTED HERE AND WE TAKE AFTER THE TIME CODE INSERTION WE TAKE THE VIDEO SIGNAL AND WE PASS THROUGH THE MACHINE SO UH THIS IS UH A SIMPLE SOLUTION BUT UM WHERE WE DON'T HAVE TO CARE ABOUT THE SYNCHRONIZATION OKAY BECAUSE THE SYNCHRONIZATION PROBLEM COMES FROM THE THE GRABBING FROM THE D. V. TAPE IN IN D IN D. VIX SO IT'S AFTERWARDS WELL BUT YOU DON'T I MEAN AT THIS POINT YOU DON'T REALLY CARE BECAUSE I MEAN IN THE SIGNAL YOU CAN EXTRACT THE TIME I MEAN THE TIME STAMP IS I IN THE SIGNAL SO IF YOU DROP SOME FRAME WHICH HAPPENS SOMETIMES WHEN YOU DO COMPRESSION OR ACQUISITION UH YOU YOU UH EV YOU WILL AUTOMATICALLY FIND THIS IN UH THE SIGNAL RIGHT I MEAN IT'S ENCODED IN THE IN THE IMAGE SO YOU CAN YOU CAN DO IT OTHERWISE UH IF THERE IS SOME FRAME DROPPING YOU HAVE TO RELY ON THE NUMBER OF FRAMES YOU ARE COUNTING MORE OR LESS I SUPPOSE TO TO ASSESS IT UH SO YOU HAVE YOU HAVE SOME PROBLEMS THEN YEAH OKAY OKAY SO THE F LAST ONE IS UH THE FIRE WIRE ACQUISITION UH I JUST WHICH I WHICH WAS MORE OR LESS T. N. O. S PROBLEM OKAY WITH RESPECT TO FRAME DROPPING RIGHT MM THEY DIDN'T HAVE TOO MUCH FUN GRABBING THE PROBLEM IS WAS THAT IT WAS NOT SYNCHRONIZED SO THE TIME CODE WAS WRONG FOR FOR THE DIFFERENT VIDEOS THEY HAD THE UH UH AT THE BEGINNING OF THE VIDEO YOU IF YOU SAW THE TIME CODE IT WAS SIX HOURS NI UH FIFTY MINUTES AND H THERE FOUR HOURS THIRTY TWO MINUTES SO IT'S IT WAS A PROBLEM WITH THE TIME CODE WELL THAT'S WHAT THEY DID UH MANUALLY AFTER THE AFTERWARDS BUT THEY DIDN'T HAVE TOO MUCH FRAME DROPS IN FACT NO THEY D YEAH YEAH YEAH I'M SURE BECAUSE WELL IT'S MANUAL TO TO SYNCHRONIZE IT THE FRAME YEAH THAT'S WHAT THEY DID BUT I I HAD THE FEELING THAT THEY HAD ALSO SOME FRAME DROPPING THAT WAS UH NO OKAY OKAY THEN THAT'S FINE OKAY UM IN FACT THE THE MAJOR PROBLEM REGARDING ACQUISITION SYSTEM IS ALWAYS THE SYNCHRONIZATION AND FOR THAT FIRE WIRE IS GOOD I MEAN FIRE WIRE WAS A PROJECT NOW THE PROJECT IS UH STAND BY UH WE DON'T MOVE TO THAT PROJECT I AM BUT I AM JUST GOING TO TALK ABOUT THIS ONE UM SO WITH ACQUISITION WITH ACQUISITION SYSTEMS UH THE MAJOR PROBLEM THE MAJOR PROBLEM IS UH THE SYNCHRONIZATION AND FIRE WIRE GIVES YOU SOME UM SOME WAY TO BE SYNCHRONIZE IN FACT UH THIS IS UH I JUST WANT TO TO DESCRIBE HERE THE BUS THIS UH YEAH THIS IS OF THE BUS WHERE YOU CAN SEND YOU CAN SEND SOME PACKAGE AND ANY DEVICE WE WHICH WANTS TO SEND A PACKAGE A P A PACKET SORRY SHOULD ASK UM THERE IS A MANAGER OF THAT BUS
