Video Description

Today's lesson covers the connector types that allow us to transfer video between our computer or display device. We begin with DVI. The DVI connector comes in several types and we diagram to demonstrate to the differences between each type. For example, DVI-a only transfers Analog, where DVI-D only transfer Digital signals, and the DVI-I transfer both. From the diagrams you'll be able to distinguish between the Analog and Digital type, discuss how each device transmits its signal, and articulate the benefits of the DVI-I (integrated) cable connector. The display port connector is a 20-pin connector that resembles an HDMI connector but transmits fewer signals. We'll discuss what its function is, why it would be used, and how it works to transmit its signal type.

Hi. Thank you for joining us here today at cyberia dot i t. My name is Anthony and I'm your local subject matter expert here For a plus. Today we're gonna be talking about different connector types and different connector cables. Some of the first types of connectors that we're going to cover today are going to be displayed connectors.
00:20
Now these are the type of connectors which allow us to transfer video between our computer
00:25
or our display device.
00:28
It's just basic video output. Whether being a longer digital, there's several different types of connectors and their several ones that we need to cover.
00:36
So one of our first connector types is going to be a devi I
00:41
now our d b I stands for digital visual interface and commonly you'll see it as a cable with a white connector at the end having multiple pins. The connector in actually looks like so with the receiving pins. The Devi I connector comes in a few different types. We have d v I. D. This is going to be digital.
01:00
Only
01:00
now our Devi I dash d connector is going to look similar to this. It has 24 pins in rows of three or in the connectors case is 24 square holes. When you're looking the connector on the right side, you'll see what looks like a single cross or a tea.
01:19
Now this devi I dash d again this digital on Lee
01:23
and cannot transfer any sort of analog signal. That's where our Devi I dash a comes in. Our Devi I dash a is actually a devi I cable, but it only transfers analog signal. This may be seen often in converters,
01:38
and our Devi I dash a connector looked very similar to start off with. But we'll notice that it actually has quite a few Les pins that are Devi I dash d and over on our right side, we have the cross end. We'll actually have the cross end with four additional pins on it.
01:57
In these four additional pins over here
01:59
are what transfer our analog signal. Now we do have a balance between the two, and that's our Devi I dash. I r D v i. D. I is her devi I integrated and it has it all transfers digital as well as analog. This is very useful and systems where we have a digital display and ueno It may need to
02:19
convert that to an analog display somewhere along the line.
02:22
So we want to carry that extra signal just in case. So again, that'll be our d B. I dash I that's digital and analog that will look like a full devi I dash d connector. Except on our right hand side, we'll have our analog pins are four additional pins so we can see the difference between our Devi I dash d
02:42
DVDs a on our Devi I dash. I can
02:44
moving on to another. One of our connectors is our display port connector. Our display port connector is another digital display port. Now this is a separate connector again altogether from our Devi I but it is still a digital display connector. So our display connector is going to be a 20 pen and
03:02
when you look at it, it looks similar.
03:06
It'll look a little similar to an H. D M I connector, but slightly different. We don't unfortunately have a demonstration here, But our 20 pen display connector its sins less signals than Devi i or HTM I. But it's still a source of digital signal which is okay. It's maybe a step up
03:24
for us above v g. A.
03:27
And it may be able to be used in a situation. We don't have the option to use a DV eye on HD am I? So it comes in handy. But if possible means we may want to take a step up from our display connector and go full devi I or each day am I?
