futurehey Don hi I'm Scott Patterson Directorof Marketing here at be incorporatedhome of the BOS we're here in ourheadquarters in Menlo Park Californiajust north of the Stanford campus we'reglad you could spend some time with ustoday we'll spend most of the day takinga look at the be operating system itselfand the technologies within it that makeit so great at handling the real-timemanipulation of high bandwidth digitalmedia and low cost personal computersBefore we jump into the OS itselfthere's a couple of people we'd like youto meet so why don't you follow mehello good afternoon and welcomelet me try and explain what we're tryingto accomplish with the BOS first we setout to start from a blank slate thisfrees us from all the layers and theyears of bug fixes and improvements thatyou see as sediments on all theoperating system platforms and make themslower harder to debug and really makeit make it difficult to make the best ofnew audio and video technology which iswhat we are concentrating on with a POSwe are trying to create the idealplatform for the development of a newbreed of new digital media applicationsyou've seen the success of linux so ifyou want a sound buy to to summarizewhat we are trying to accomplish we'retrying to become the linux of audio andvideo applications so now I hope you'llenjoy the demo and the next person to toexplain what we are doing will be FrankBozeman our vice president of developerrelations you're about to see ademonstration of the vos the operatingsystem we've built from the ground up tobe the best in the world for peopleworking with today's rich media audiovideo and images if you're consideringdeveloping software for the vos thanwhat I hope you see is the opportunityto build groundbreaking applications fora platform where the playing field istruly level I also hope you see afocused market of customerseeking software that goes well beyondthe functionality possible with today'soperating systems if the demonstrationyou're about to see piques your interestthen please do check out our website tolearn more about the variety of programswe have in place to help you developyour products and bring them to marketso when you're ready to edit media farmore efficiently than you may havethought possible or when you're ready todo some development on a system thatmakes programming fun again then comespend a few hours with the BOS of courseif one day you decide not to go backagain we won't complain thanks for yourtime and enjoy the demonstration we'reready to take a look at the BOS butbefore we jump right ini'd like to tell you a little bit aboutthe computer so you can gauge theperformance that you see this computerhas 64 megabytes of RAM a three gigabytehard drive and two Hauppauge videocapture cards these are about $70 cardsthat you can purchase at your localcomputer store and we're using them tocapture uncompressed video to play withinside of the operating systemeverything you see on the screen will bedone in software there's no additionalaccelerated hardware the only uniquething about this computer is theprocessor rather the number ofprocessors we're utilizing a dualPentium 2 system running at 266megahertz although we'll utilize bothprocessors for most of the demo at timeswe'll turn one off so you can gauge howthe system runs on a unit processormachine ok let's get startedwe haven't made any radical userinterface changes in the BOS the ideawas to make the learning curve of theBOS as gentle as possible so there's afamiliar concept of disks folders whichyou double-click on and files andfolders inside of those everythinginside of the BOS is live so as imanipulate this window you have liveupdating even as i open and close thesize of the windowthere's context-sensitive menus so if iwanted to move this item somewhere elseon a disk i simply navigate down tohierarchical file system and place itwhere I want this utility up in thecorner is called the desk bar it does anumber of things the first and mostobvious is it keeps a list of yourcurrently active applications if I runthe clock application you'll see it'slisted in the desk bar I can customizethe look and feel the desk bar placingit on almost any fringe of the screen Ican compress it place it along the topof the screen in any corner along thebottom and I'll leave up here in thiscorner which is where I'm used to usingitone thing we strive for in the BOS is avery responsive user interface the wayi'll demonstrate this is by bringing upa number of items on the screen at thesame timefirst i'll launch a sound this is a16-bit stereo audio file being played at44.1 kilohertz off the hard drive eventhough we're playing this audio file Ican move Windows around the strangeaccess menuslaunch applications I'll launch our CPUmonitor as well as our Mandelbrotso I can iterate in real-time down onthe Mandelbrot and even bring up a moviethe first thing you'll notice as I movethis movie around the screen is thatnothing stops processing the moviecontinues to play all of its frames theaudio continues to play without anyglitches you can have up to nine virtualworkspaces inside the BLS I'll bring upthe workspaces preference panel and thebest way for me to really demonstratethis is also to bring up the screenpreferences panel here I'm working in aworkspace and thousands of colors and ifI switch to workspace two and then dragthe screen preferences panel acrossyou'll notice this workspaces in 256colors and if I go to the thirdworkspace and drag across again we'reworking in millions of colors this is agreat way to organize how you work withyour applications perhaps productivityin one window video editing in anotherit's also a great way to previewgraphics and different color depths I'llbring up a graphic and you can see whatit looks like in millions of colors andif I simply switch to the 256 colorworkspace and drag that graphic acrossyou can see what it looks like on an8-bit machine across the internet theBOS is a fully symmetric multiprocessingoperating system that means that theentire OS from kernel to applicationscan take advantage of more than oneprocessor in a system in fact the BOShas been run on systems with up to eightprocessors this means as you go from oneto two processors you get a nearly 100%increase in performance this applicationthat I'll show youcinema4d takes advantage of thesymmetric multi-processingin the BOS i'll load up an imageand also load up our CPU monitors so youcan see the level of activity on each ofthe CPUs the more green you see on eachbar the more that particular processoris being utilized I'll go ahead andselect render the threads in thisapplication are set to have a partnersuch that they soak up whatever excessCPU is available and that's why you seeboth processors go to work on theproblem let me turn off a processor fora minute and go ahead and re-render thisimage what you'll notice as I turn theprocessor on and off is the renderingspeeds up and slows down the vosdynamically handles allocating threadsto whatever the next available processoris today your thread might run onprocessor 1 and tomorrow it'll run onprocessor for the vos implementsprotected memory applications and eventhe operating system processesthemselves all run in their ownprotected memory address spacethis means no single misbehavingapplication could take down theoperating system or any otherapplication we've intentionally crash anapplication inside the B operatingsystem what you see on screen is theresulting error message although thisapplication is crashed we can still runother applications I'll go ahead andlaunch a movie and the clock applicationwe can return to our error message andget details about the crash exactly whathappened and where and even go into thedebugger at this point we could dothings like seeing the state of thememory at the time of the crash as soonas you exit the debugger the VMS cleansup and you can launch that applicationagainall the networking in the BOS is basedon the internet standard tcp/ip protocoli'll bring up the network preferencespanel for a moment we'll take a littlelook we have support for multiple IPaddresses multiple Ethernet cardsthere's dial and support through PPP ourmoto support is quite extensive we alsohave a built-in ftp server for filetransfers and a built-in telnet serveryou can actually log in remotely to theBOS and launch applications from thecommand line you can make any changes tothe networking on the fly without havingto restart the operating system itselfwe have a built-in web server and webbrowser our web browser is mostly herebecause all the documentation in the BOSis written in HTML and we thought it'dbe nice if you could read it right fromstart up we refer to the BLS as themedio s that's because it's beendesigned from the ground up to handlethe real-time manipulation of highbandwidth digital media such as graphicsaudio and video let's take a look atgraphics I'll bring up this 3d book whatyou can see is I can manipulate thepages in real time with good performanceturning them back and forth whipping andwarming them corresponding to how hardor how soft I pull the mouse a gradebook is pretty boring so let's dress itup a little bit I'll put this image hereand this image down here now when I grabthe pages you'll notice that the imagestays nicely map to the availablesurface of the page no matter how hardor how soft I pulled the novels we'renot limited to static images I can graba couple of movies here place one hereand one here and again grab the page andturn it back and forth what you'llnotice is the movie continues to playwhile it's being mapped to the availablesurface of the page things don't stopprocessing just because I'm utilizingthis one object real-time audio controlis another area where the pos-xthis application is essentially a 3dgraphical representation of a soundboardI have 16 separate stereo CD qualityaudio tracks being run off with a harddrive at the same time I can manipulateany one of them individually for exampleI can take this audio track give it alot of reverb charge me up all the othertracks I saw my future enlarged and thenextremes off of the threads incorporatedinto the foreground I can bring all theinstrument play and fade the entire songinto the background and then bring itback to the foregroundthe BLS also handles the viewing andreal-time manipulation of video you cansimply watch TV on your PC we preservenice motion on the screen even as youmove this video window around you canresize the window and in this case wedon't lose a single frame I can evenhave windows fall in front of a videowindow and we do intelligent clippingyou can use your PC as a VCR we've gotour source material coming in I'll go tothe transport screen and begin hittingrecord we're now recording uncompressedvideo right to the harddriveI'll get a few seconds of material hitstop and play we continue to play ouroriginal source but we're also notplaying the uncompressed video we recordit to the hard drive back in this windowhaving two video windows one over theother is a snap for the BOS let's takeit a step further and apply real-timevideo effects all in software I'll bringup my second source so I've got twosource windows and a compositing windowI'll make that window much bigger so youcan see the effects that I'm going toapply so here in real time on software Ican come in and do something like avertical wipe a horizontal slide fromone source to the other something alittle more complex like a sparkleeffect from one source to the other orcheckerswe can add a nice dissolve where weactually have transparency on bothsources in the same window at the sametime and even do a page flip the otherthing to notice here is as I do thatpage flip when the very end of the pagestarts to curl we actually reverse theimage and play it on the back side ofthe page flip although we've seen somegreat performance so far we haven'treally stressed the be operating systemout just yet let's throw a bunch ofapplications at it and see just how farwe can go I'll start by launching thesefive applications let's place our CPUmonitor right here up at the top of thescreen so you can always see the levelof activity on the CPUs fonts inside ofthe BOS are all scaleable in real timeup and down in fact I can do this as Icycle through the installed fonts I canapply any level of shearing back andforth and even rotate in 360 degreeslet's make that a little smaller andmove it out of the way we've got ourminesweeper down here and also our webbrowser which I'll send off to the Bhomepage will make our now they broughta little smaller and iterate down onthat and place it over herelet's bring up some TV as well I'll makethat a little bit smaller and place itdown herewe'll bring up a couple movies as wellI'll place this one here in the cornerand this one just above it let's alsobring up the game and as that comes upyou'll notice on our CPU monitor thatwe're at just about a hundred percentutilization the BOS has a nice longdegradation curve so I can go out evenpast 100 percent let's bring up some 3dgraphics I'm going to use this pulsingimage for this part I'll make it alittle bit smaller and map an image ontop of itso even though we're out past a hundredpercent I'll turn off one of theprocessors effectively having theperformance of this machine and whatyou'll notice is applications don't cometo a screeching halt our video sourcecontinues to play at full 30 frames asecond our movies are continues to playsmoothly you'll notice that the pulseanimation is starting to get a littlebit staggered but that's because we dointelligent prioritization of threads assoon as I turn this processor back onyou'll notice that the pulse animationspeeds up again I'll turn the processorback off and back on againthe most important thing to note here iseven though we're having the performanceof the machine we still have a stableoperating system that's the end of ourdemo and our day here at be if you takeaway anything we hope it's this the V usis designed from the ground up to handlethe real-time manipulation of highbandwidth digital media on low-costpersonal computers if you'd ever like tostop by for a personal visitwe give live public demonstrations ofthe BOS every friday
