That the field (lĩnh vực) that we decided to do it the choice we made. Now why music? We love music, and it's always good to do something you love.
00:12
More importantly, music's a part of everyone's life. Music's been around forever (mãi mãi); it will always be around. This is not a speculative market (thị trường mang tính đầu cơ), and because it's a part of everyone's life, it's a very large target market (thị trường mục tiêu) all around the world. It knows no boundaries. But interestingly enough, in this whole new digital music revolution (cuộc cách mạng âm nhạc kỹ thuật số), there is no market leader. There are small companies like Creative and Sonic Blue,
00:42
and then there are some large companies like Sony that haven't had a hit (sản phẩm thành công) yet. They haven't found the recipe (công thức). No one has really found the recipe yet for digital music. And we think not only can we find the recipe, but we think the Apple brand (thương hiệu) is going to be fantastic because people trust (tin tưởng) the Apple brand to get their great digital electronics.
01:03
So let's look at portable music. Let's look at the landscape (bức tranh tổng thể). The first thing, if you want to listen to music portably (một cách di động), you go buy a CD player. That's one way to go — about fifteen, ten to fifteen songs. Or you can buy a flash player, but by one of those, you can buy an MP3 CD player, or you can buy a hard disk-based jukebox player (máy phát nhạc ổ cứng). These are the four choices for portable music right now. So let's take a look at each one of those.
01:32
Cost about seventy-five dollars. Holds ten to fifteen songs on a CD. It's about five dollars a song.
01:41
You go buy a flash player, pay about double (gấp đôi), about a hundred fifty dollars. Holds the same ten to fifteen songs — ten dollars a song. You know, an MP3 CD player, an MP3 CD, which you can burn (ghi vào) on your computer, costs about a hundred fifty dollars but holds a hundred fifty songs. You get down to a dollar a song. Or you can go buy a hard drive jukebox player for about three hundred dollars. It holds about a thousand songs and costs about thirty cents a song.
02:11
So we looked at this and studied all these, and that's where we want to be. That is where we want to be.
02:19
And we're introducing a product today that takes us exactly there. And that product is called iPod.
02:49
What is iPod? iPod is an MP3 music player. It has CD-quality music, and it plays all of the popular (phổ biến) open formats of digital music — MP3, MP3 variable bitrate (tốc độ bit thay đổi).
But the biggest thing about iPod is it holds a thousand songs. Now this is a quantum leap (bước nhảy vọt), because for most people, it's their entire music library (thư viện). This is huge. How many times have you gone on the road with a CD player and said, "Oh, I forgot the CD I wanted to listen to"? To have your whole music library with you at all times is a quantum leap in listening to music.
03:17
The coolest thing about iPod is that your entire music library fits (vừa) in your pocket. You can take your whole music library with you, right in your pocket. Never before possible. So that's iPod.>> Form đăng kí giải đề thi thật IELTS 4 kĩ năng kèm bài giải bộ đề 100 đề PART 2 IELTS SPEAKING quý đang thi (update hàng tuần) từ IELTS TUTOR
03:47
How do we possibly do this? We start off with an ultra-thin (siêu mỏng) hard drive. We've got a 1.8-inch diameter hard drive. This is 0.2 inches thick — super thin. And that hard drive is 5 gigabytes (5 GB, đơn vị lưu trữ dữ liệu) in capacity. Five gigabytes, which holds a thousand songs at 160 kbps of MP3 compression. Very high-quality — a thousand songs on this 5 GB drive.
04:17
We've built in 20-minute skip protection (bảo vệ chống bỏ qua). That's not 20 seconds — 20 minutes. So you can take iPod bicycling, mountain climbing, jogging, you name it, and you're not going to skip a beat.
04:38
So, we've got this 5 GB drive that holds a thousand songs. How do we get the thousand songs on? We don't want to wait. So, we've built in FireWire (kết nối tốc độ cao FireWire). Now, Apple, as you know, invented FireWire.
05:08
Let's talk about a thousand songs now. On iPod, with FireWire, it is under ten minutes. On a USB player, it is five hours. Can you imagine that? You get your USB player, you want to load a thousand songs — you can watch it for five hours while it loads the songs.
05:33
Under ten minutes with iPod. It's 30 times faster than any other MP3. Huge win.
06:02
We're using a rechargeable (có thể sạc lại) lithium polymer battery. This is a more advanced battery than we even use in our portable computers.
06:31
To your Mac, it actually charges the iPod over that single FireWire cable. So you don't have another charging cable (cáp sạc) to worry about. It charges over FireWire every time you plug it into your Mac.
07:00
So, 10 hours of continuous (liên tục) music playback with a remarkable new battery technology.
07:36
Ultra-portable. An iBook is really portable, but this is ultra-portable. Let me show you what I mean.
08:03
It also only weighs 6.5 ounces — that is lighter than most of the cell phones (điện thoại di động) you have in your pocket.
09:03
So, this amazing little device holds a thousand songs. And it goes right in my pocket.
