And so for the codec, we've selected HEVC because it meets all of these requirements.

所以我们选择了HEVC 作为编解码器，因为它符合上述所有要求。

Those include the ProRes codec and a display engine that powers ProMotion and the always-on display.

其中包括 ProRes 编解码器以及为 ProMotion 和常亮显示提供支持显示引擎。

These values are then sent to the audio codec, which converts the digital values into an analog electrical waveform.

这些值随后被发送到音编解码器，将其转换为拟电波形。

In this scenario, the codec performs a digital-to-analog conversion, or DAC.

在这种情况下，编解码器执转换， 或称为DAC。

If you're wondering how audio can be represented by ones and zeros, take a look at this episode on audio codecs.

如果你想知道音是如何用一和零表示，看看这一期关于音编解码器内容。

Just two years later, when the codec problem was solved by Adobe Flash and when broadband penetration crossed 50 percent in America, YouTube was perfectly timed.

仅仅在两年之后，当 Adobe flash 解决了编解码问题，并且全美普及度达到 50% 后，YouTube 正中时机。

This circuit board is connected to and folded on top of a second circuit board, which contains a low-power stereo audio processing chip, or audio codec.

这块电路板连接并折叠在第二块电路板上，第二块电路板包含一个低功耗立体声音处理芯片，也就是音编解码器。

It was too hard to watch video content online, you had to put codecs in your browser and do all this stuff, and the company eventually went out of business in 2003.

要想在网上看视太困难了，你不得不向浏览器加入多媒体字信号编解码器，要加入所有编解码器，最后这家公司最终在 2003 年退出了市场。

In the scenario we just talked about, the audio codec converts the music or podcast data from a set of digital values or numbers into an analog waveform.

在我们刚才讨论情景中，音编解码器将音乐或播客据从一组字值或字转换为拟波形。

Codecs are used in every piece of technology we use in order to convert certain types of data into other types, while compressing or decompressing the data.

编解码器用于我们使用每一项技术中， 以将某种类型据转换为其他类型据，同时对据进压缩或解压缩。

In fact, this video you're watching is downloaded as a compressed video file, and a video codec is actively decompressing this video's data as you watch it.

事实上， 你正在观看这个视是以压缩视文件形式下载，而视编解码器在你观看同时， 正积极地对该视据进解压缩。

On the bottom of the PCB are a set of connectors for flat cables to be plugged into, an audio codec microchip, and an accelerometer and gyroscope microchip.

在电路板底部有一组用于插入扁平电缆连接器、一个音编解码芯片以及一个加速度计和陀螺仪芯片。

However, audio codecs can also do the reverse by encoding the analog signal from the microphone into a digital set of values, which is an analog-to-digital conversion, or ADC.

然而， 音编解码器也可以反过来将麦克风产生拟信号编码成一组字值，这就是拟到字转换，或称ADC。

Well, codec stands for coding and decoding, and in general, it's either a piece of software or hardware that converts data or information from one format into another format, thereby compressing or decompressing data.

好吧， 编解码器指是编码和解码，通常它是一段软件或硬件， 能够将据或信息从一种格式转换为另一种格式，从而实现据压缩或解压缩。

When the digital information, or the long list of numbers, is fed into the audio codec, the audio codec plots all the points on the graph, connects the dots, and smooths the line between the points.

当字信息， 即那一长串字，被输入到音编解码器时， 编解码器会在图表上标出所有据点，将它们连成线， 并在各点之间平滑过渡， 随后将生成拟波形传输给扬声器， 从而产生声音。

It was like, huh, it could be that you're just… it could be some sort of strange processing thing or it could be some codec, and it… but it's a bit baffling and a bit hard to fix.

就像，嗯，这可能是你只是......它可能是某种奇怪处理东西，或者它可能是某种编解码器，而且它......但这有点令人困惑并且有点难以修复。

Thus far, we've made a few episodes that help to explain other parts of these wireless headphones, such as noise cancellation in the audio codec, and we've made even more episodes that dive into the different parts of your smartphone.

到目前为止， 我们制作了几集视来解释这些无线耳机其他部分，比如音编解码器中降噪功能，而且我们还制作了更多集视来深入讲解智能手机不同部分。
