Abstract Good morning. My name is Tim Heidmann and I'd like to welcomeyou all to this panel, which is entitled Future Directions inDesktop Video, and I'd especially like to thank all you people whostayed up a little late on Thursday night to come to this panel.It's really good to see you all out there.I've gotten word that this panel is being transcribed. They'reputting together a booklet, so they're taking the slides and thestills from the videos and all the things that we're saying. So I'djust like to take this opportunity to say hi to the person who'stranscribing this and sorry you couldn't be here today, and Iwanted to let you know that the word of the day is Neopraseodymium,and I hope you've got your scientific dictionary close by.When we first started putting this panel together, I talked tomy friends who were involved in a number of different areas invideo, and the question that came to the forefront very quickly iswhat exactly desktop video is. There's been a lot of talk about it,a lot of magazine articles. It's a good buzz word. But we all feltit incorporated a whole bunch of different areas that weren'teasily put into one category.We did agree that the name of desktop video came from the fieldof desktop publishing. In desktop publishing, which has been arapidly growing field in the past few years, the whole point isthat we've got a computer bringing together elements from theoutside world, creating elements inside the computer, putting themall together and coming up with a final product. The point is it'sall done inside the computer. Again, it does the things thatcomputers do really well -- like text editing and graphics designand layout. And it was made possible by the fact that these highquality printers -- laser printers -- had come out that you couldproduce a very high quality output from it.Well, on the video side, there is a similar development. Thatis, it's possible now to make video animation completely within thecomputer. There are software packages for modeling objects, forcreating animation, for rendering very high quality images andoutputting them directly to tape. And I guess you could call thatdesktop video. You're doing the same thing as you're doing indesktop publishing, but now you're producing videotape andanimation.But really what's happening in video is a lot bigger than that.I've kind of come up with this map. If you look at the entire videoprocess, you can split it into four parts. The first being creatingthe elements, which I've called Source here. Now that would includesuch applications as computer graphics, generated completely insidethe computer, but also things like pointing a camera at someone orsomething, things like medical imaging. Basically the creation ofthe images.The second step would be assembling those images and probablysome audio into a master video production. Just about everythingyou do in video involves some sort editing to it, even if it's justputting a title on the beginning.The third area is the distribution. How do these images get outto the outside world? A lot of times it's just making lots of VHScopies and mailing them to your friends.And the final part is how do you look at this videotape? How doyou use video in your application?What we're going to talk about today, when we talk about desktopvideo, is actually all these areas. The speakers today have anumber of different backgrounds. We'll be addressing this in anumber of different ways.Basically the reason we're doing this panel today and why it'simportant now is because there are a lot of developments that arebringing video into the reach of more application areas. People areinterested in what can be done with video, want to know what'shappening and what the developments are. Specifically the thingsthat we're seeing are the appearance of higher quality consumerformats. That is, videotape recorders, players, that are availableat consumer affordable prices, but give you enough quality to letyou duplicate and edit a little better than VHS or just plain 8millimeter.Computer graphics hardware and software is becoming lessexpensive and more accessible. The fact that you can buy editingequipment for these new consumer formats and do a really good jobof putting together a final videotape without going to apostproduction house. New distribution methods and integrated videoapplications like DVI, which allow much broader use of video. Sothere's more incentive to produce these things.These are the areas we're going to be talking about today, andjust keep in mind this map, and I think if we can reference thedifferent things we'll be talking about to this map, maybe it willall make sense.I'd like to introduce the first speaker today who is MichaelMacKay, currently of the Sony Advanced Video Technology Center,formerly of Diaquest; before that with Atari Research. Michaelbrings a strong background in computer graphics, in videoproduction, interactive video applications, and without furtheradieu, Michael.
