Video Description

In this lesson we explore additional input devices which we can specifically label as multimedia devices. Devices such as webcams, digital cameras come to mind. Digital cameras connect to computing systems in different ways such as USB or micro USB, or Firewire and will often require software to assure functionality. Its purpose is the transfer of images. They will also have micro SD cards which can be removed from the camera and inserted directly into the card reading port for a computing system, which then reads it as a storage device. The higher end devices such as camcorders plug directly into computer and eliminate configuration overhead with real-time transfers, but it's still safer to have your image data saved as a security measure. Webcams vary as well, some are built-in, some are added on which require additional software. Some also have additional capabilities such as microphones as well as resolution quality which is sufficient based upon the need and use of the device. Lastly is the MIDI which is a specialized port that allows computing systems to capture output from a musical device.

Video Transcription

00:04
We also have additional devices called that we label as multimedia device is now. Some of these may still be input devices such as a webcam that
00:13
captures our image and puts it into the computer. They're still under input devices, but we also categorize them as multimedia device is now our first multimedia device that we're gonna talk about is going to be, ah, digital camera.
00:26
Now a digital camera can connect to our computer in a few different ways. Ah, ah, Lot of them may have a USB or micro USB port on the side that allows us to take the camera and plug it directly into our computer and transfer photos that way, or copy them over from our camera onto our computer.
00:45
So because we're actually plugging our camera into our computer,
00:49
well received software a lot of times with our computer, this will help to manage the photos and help our computer to understand what this device is that's connecting into it and how to interact with it. So we always want to read our instructions when we're getting our cameras as faras how to connect everything properly.
01:04
Now, not only can we connect up our camera using a USB or sometimes a FireWire cable. Ah, lot of our cameras will actually come with removable memory cards, whether this b A S d card or ah, larger card or micro SD card, depending on the size and type of the camera.
01:22
Ah, lot of times we can actually remove these SD cards
01:25
and plug them directly into our computer as storage devices. Now, this sort of removes a lot of the hassle of having to
01:33
get our computer to recognize our camera and know how to transfer the data from it and know what supposed to be doing by actually just taking that seat are taking the SD card. Taking that card and just plugging it directly into our computer is a storage device because our computer sees that storage device and it immediately goes,
01:51
Oh, I know what to do with this. I can mount this and I can transfer files from this
01:55
And look, there's already some files on here and there's some pictures on here I can transfer, so it may be a little bit more straightforward and maybe a little bit easier, depending on your situation,
02:04
but we want to go ahead and add on our digital cameras. In addition to having removable media some of our higher end
02:12
digital cameras, such a czar DSLR digital cameras or even some of our higher and cam quarters or video cameras, they can actually plug directly into computers, some of them, and transfer information directly from the camera at in real time to the computer. This saves is with
02:29
saves us a little bit of had the hassle of having to transfer it later, because we can do it in real time.
02:34
But we may want to actually have that data stored hard on our camera are hard on. Our cards are on our recording device. Just in case something happens. We have those additional locations where it's stored. But in a case where we're doing something such as a photo shoot, we're doing a long video recording
02:53
could be helpful to have that ability just to transfer it
02:55
directly to the computer, especially our computer has, which typically does more storage space than through the actual recording device on our camera. Moving on from
03:07
standard cameras to a different type of camera, we're not gonna talk about our webcams now. Webcams come in
03:15
all different shapes and sizes. Again, we have built in webcams that are already put on our computers or on our monitors on our laptops. Now we have all all in one tablets are all in one computers with webcams built right into the front. Sometimes we have cameras on the back and then a front facing camera on the front,
03:32
and we also have
03:35
webcams that we plug into our computer and add on.
03:38
These are all different forms of the webcam, and they all function in different ways. Some of them have built in microphones. Some of them have higher resolutions than others. Some of them have a larger range of view. It
03:50
it really depends on what you're looking to get out of your webcam as faras what you're using it for.
03:55
If you're using your webcam, just this, say Skype or to Google chat sometime from time to time with your family members or your friends. Then you're if you have a laptop with a built in Web camera, this may suffice for you. This may be all you need, and you just use it from time to time and you don't really need it. for anything else. But say if you're using a camera for high end Rick
04:15
courting
04:16
or to post videos onto YouTube or to use the camera for
04:23
videoconferences with. If you're teaching students over the Internet or if you're interconnecting with business partners around the world, you may want to use a webcam that has a bit higher resolution so that you get that clearer picture. And, in the case of, say, a business partner and you're using Skype Connection,
04:41
it looks a bit more professional rather than having ah, grainy camera.
04:44
But again, it all depends on your situation, and it all depends on which
04:49
again. You also have to account the budget in tow. What year? What type of camera you're gonna buy. What type of Web cam you want you want to buy on. Each situation is different, so it's best to do research and get the best value you can for your webcam. Or just use the built in webcam that you have on the computer. If that situation, if that
05:08
is good enough for your situation, we have an example here of one of our Web cams, and as we can see, it's actually USB connected Webcam and this Web. Kim did come with additional CD and drivers in order to install its Our computer would recognize it on the front of our Web cam, we noticed that we do have a place where it's it acts as a microphone. It can
05:27
receive sound,
05:28
and we also see that it shoots in HD 7 20 And that's gonna be the resolution of our camera. Now this camera does have its own little stand, and I can put it on top of my laptop. I can stand it up on the desk and use it. The point at me and that a lot. And it's, ah, decent resolution. It works pretty well, and it
05:46
is compatible with my computer. That's always something you need to check before you buy the Web
05:49
campus. The type of computer, the type of operating system that you're running is that webcam compatible with it because the last thing you want is to buy a webcam, spend money on it, do the research and then actually try to install the webcam on your computer, only to find out that your computer version isn't compatible with the webcam.
06:09
So that's an always important consideration to check
06:11
one of our other types of multimedia about media devices that we may encounter are called midi enabled Devices him I d. I.
06:19
Now we've talked a bit earlier about
06:23
R M I. D. I devices basically being our musical instrument devices that we plug in using our M i D. I cable into our ports. These essentially allow our computer to just capture data directly from those musical devices using that specialized port
06:43
that's gonna be like an electronic drum set or
06:45
possibly a keyboard or a microphone.
06:48
And this multimedia device actually
06:53
captures this data are captures the sound directly from the musical instrument. We want to make sure that we're using the correct cable on the correct port for these types of devices. And again, they do have their own specialized type of port. So far, computer doesn't support that. We may need to get an expansion card that does,
07:10
or we may need to look at a different device. If we aren't in a situation where we
07:14
can actually use an expansion card or we don't have any ports that support that.
07:18
We want to make sure that if we need to any additional software drivers that we need to install, We have ready and we're going through. It is Theo instructions Tell us this is a quick recap we have are a couple of multimedia devices that we need to know about. And these multi media devices are also too
07:35
types of input devices. They're giving us information,
07:39
but they're more class. They're more so our multimedia devices. We have our digital camera and our camcorders that we talked about
07:48
Webcams and M I. D I devices. We always want to make sure that we're using these devices properly, and we're always reading our instructions and running into any type of software we need Thio.
