- [Presenter] If you go to a big arena concert,

- [主持人]如果你去看一場大型的競技場音樂會、

像泰勒-斯威夫特的 "年代 "巡迴演唱會、

祈使句型

a buzzer-beating three-pointer in the playoffs,

在季後賽中，一個在蜂鳴器上打出的三分球、

turning the audience into part of the show,

with synchronized light displays at the touch of a button.

只需按下一個按鈕，就能實現同步的燈光顯示。

- It's funny, because oftentimes people think, like,

- 這很有趣，因為很多時候人們都認為，比如、

or, like, there's a lot of, like, AI advanced technology,

或者，有很多，比如，人工智能的先進技術、

but we really like the old school technology (laughs)

但我們真的喜歡老式的技術（笑）。

- [Presenter] This is the tech behind LED wristbands.

- [演示者]這就是LED腕帶背後的技術。

Montreal-based PixMob is a leading company

總部位於蒙特利爾的PixMob是一家領先的公司

but they have done previous Taylor Swift tours,

但他們以前也做過泰勒-斯威夫特的巡演、

we do most of the major tours in North America.

我們做的是北美的大多數主要巡迴演出。

Let's start off with the simplest, RF wristbands,

讓我們從最簡單的，射頻腕帶開始、

that receive a radio frequency communicating

the precise timing and colors for each band.

準確的時間和顏色，為每個樂隊。

- The two white squares here are the two LEDs,

- 這裡的兩個白色方塊是兩個LED、

that receives radio frequency and gives it to the computer

接收無線電頻率並將其提供給計算機。

and then the computer will light up the LEDs based on

然後計算機將根據以下情況點亮LED燈

- [演示者]這就是PixMob使用的東西

為尼克斯熱火隊系列賽的第五場比賽。

When fans went to their seats at Madison Square Garden,

當球迷們走到麥迪遜廣場花園的座位上時、

they found one of these RF wristbands waiting for them,

他們發現有一個這樣的射頻腕帶在等著他們、

each one pre-programmed to be a part of a different group.

每個人都被預設為不同群體的一員。

So a wristband in this section, for instance,

is programmed to be in Group 1 for one effect,

operator, Averil, serves as the conductor.

When one of the programmed effects is activated,

當其中一個程序化的效果被激活時、

to create different patterns within the stadium.

以在體育場內創造不同的模式。

Or she can manually play with them based on the moment,

或者她可以根據當下的情況，手動玩弄它們、

flashing Knicks colors, orange, blue, orange, blue.

- It's really fun to kind of see the crowd get into it

- 看到觀眾投入其中，真的很有趣。

You're having them be part of the show, which is special.

你讓他們成為節目的一部分，這很特別。

- [Presenter] The signal emits from this really small box.

- [演示者]信號從這個真正的小盒子裡發射出來。

- 我們有一個非常簡單的發射器、

我們可以將其連接到一個光板上。

We like that technology because you can literally travel

我們喜歡這種技術，因為你可以真正地旅行

with the whole control system in your suitcase.

與整個控制系統在你的手提箱。

is what most other wearable LED companies use too,

是其他大多數可穿戴式LED公司也在使用的、

who do everything from Eurovision to corporate events.

從歐洲電視網到企業活動，他們都做。

like what you see at the Super Bowl or Lady Gaga,

像你在超級碗或Lady Gaga看到的那樣、

- So the same thing that you use to turn on your TV,

- 是以，與你用來打開電視的東西一樣、

it's kind of like technology that is, like, 50 years old,

但我們已經設法以一種方式扭曲了它

我們可以將數據發送到特定地點、

so that's how we create those specialized effects,

所以這就是我們創造這些專門效果的方法、

where we can almost turn a crowd into, like, a video canvas.

在那裡，我們幾乎可以把人群變成，比如，視頻畫布。

from robotic transmitters placed all over an arena.

從放置在競技場各處的機器人發射器發出。

You can see it here at a Coldplay concert last year.

你可以在這裡看到它在去年的Coldplay音樂會上。

These transmitters were placed on sound towers

Here's what that looked like in PixMob's visualizer,

下面是在PixMob的可視化工具中的樣子、

which is how it designs what the shows will look like

這就是它如何設計節目的模樣。

該公司稱它們為 "像素"，就可以了。

- These two lines are basically the center

so even if we have two transmitters right now

是以，即使我們現在有兩個發射器

doing the swipe, it still looks like one wave.

在做刷卡的時候，它看起來仍然是一個波段。

more of these moving heads in a setup like this,

在這樣的設置中，有更多這樣的移動頭、
