如今，智能电视已成为新的常态。这些智能电视主要基于 Android，可让你播放 YouTube、Netflix、Spotify 和其他流媒体服务。你甚至可以使用语音命令来控制你的智能电视。


这些所谓的“智能电视”的一个主要问题是它们可能正在[监视你](https://www.zdnet.com/article/fbi-warns-about-snoopy-smart-tvs-spying-on-you/)。你的数据在你或许知道或许不知道的情况下被收集。


这就是 KDE 的“[等离子大屏幕项目](https://plasma-bigscreen.org/)”旨在解决的问题。（LCTT 译注： <ruby> 等离子 <rt>  Plasma </rt></ruby>恰是 KDE 桌面环境的名称，和<ruby> 大屏幕 <rt>  Bigscreen </rt></ruby>很搭，因此这个惯常不翻译的名称这里翻译出来。）


### “等离子大屏幕”：通过开源技术使电视更智能

你可能了解 [KDE](https://kde.org/) 项目。它开始是一个 Linux 桌面环境项目，而在发展了 20 多年后，KDE 项目变得越来越大，这就是为什么他们创建了 Plasma 桌面环境的原因，以明确表明 KDE 不再仅仅是“<ruby> K 桌面环境 <rt>  K Desktop Environment </rt></ruby>（KDE）”了。


Plasma 项目本身具有多种用途，当然，你可以在台式机 Linux 计算机上使用它，而 [Plasma 也具有移动版本](https://itsfoss.com/kde-announces-plasma-mobile/)，你可以在基于 Linux 的智能手机上运行它，例如 [Librem5](https://itsfoss.com/librem-linux-phone/) 和 [PinePhone](https://itsfoss.com/pinephone/)。


“<ruby> 等离子大屏幕 <rt>  Plasma Bigscreen </rt></ruby>”是 KDE 的一个新项目，旨在提供类似于智能电视所提供的界面和功能。


你需要的是一台[树莓派之类的单板计算机](https://itsfoss.com/raspberry-pi-alternatives/)和一台带 HDMI 端口的电视，然后在你的树莓派设备上安装“等离子大屏幕”，将其连接到电视就行。


### “等离子大屏幕”的功能：不仅仅是媒体服务器

乍一看，它看起来很像是一个媒体服务器，但“等离子大屏幕”却和 Kodi 及其它 [Linux 媒体服务器](https://itsfoss.com/best-linux-media-server/) 不同，它不止于此。


#### 使用常规遥控器进行控制


你不需要新的专用遥控器。多亏了 [CEC](http://libcec.pulse-eight.com/)，你可以使用常规的电视遥控器。


#### 带有开源 Mycroft AI 的语音控制


“等离子大屏幕”利用了开源 Mycroft AI 项目。借助“等离子大屏幕”内置的 Mycroft AI，你可以使用语音命令播放内容、检查天气并控制智能电视的其他方面。你可以通过教它新技能来进一步训练它。


#### 传统的桌面应用程序


“等离子大屏幕”不仅提供丰富的媒体应用程序，还提供经过重新设计，适合它的体验的传统桌面应用程序。


#### 自由开源软件


最重要的是它是一个开源项目，它使用其他开源技术为你提供对数据和智能电视的完全控制。


由于它是开源的，我相信一旦发布，就会有一些供应商将其作为即插即用设备提供。


### 如何获取“等离子大屏幕”？


“等离子大屏幕”仍处于测试阶段，没有确定稳定版发布的时间表。


但是，测试版已经可以在树莓派 4 等设备上正常运行。下面是一个从事此项目的开发人员的视频。






如果你有树莓派 4，则可以从其官方下载页面上下载“[等离子大屏幕](https://plasma-bigscreen.org/#download-jumpto)”的测试版，然后按照[此处](https://plasma-bigscreen.org/manual/)的步骤进行安装。


就个人而言，我对此感到非常兴奋。我要花一些时间在[树莓派 4](https://itsfoss.com/raspberry-pi-4/)上尝试一下。你呢？你认为该项目具有潜力吗？你想试试看吗？

OK
*Brief: KDE’s upcoming Plasma Bigscreen project lets you use open source technologies to turn your regular TV into a smart one. *

Smart TVs are the new normal these days. Mostly based on Android, these smart TVs let you play YouTube, Netflix, Spotify and other streaming services. You can even use voice commands to control your smart TV.

One major problem with these so-called [smart TVs are that they probably are spying on you](https://www.zdnet.com/article/fbi-warns-about-snoopy-smart-tvs-spying-on-you/). Your data is being collected with or without your knowledge.

This is the problem KDE’s [Plasma Bigscreen project](https://plasma-bigscreen.org/) is aiming to solve.

## Plasma Bigscreen: Make your TV smart with open source technologies

![Plasma Bigscreen Menu](https://itsfoss.com/content/images/wordpress/2020/03/plasma-bigscreen-menu.jpg)

You probably already know about the [KDE](https://kde.org/) project. It started as a Linux desktop environment project more than 20 years ago. The KDE project grew bigger and this is why they created Plasma desktop environment to make it clear that KDE is no more just “K Desktop Environment”.

The Plasma project itself is quite versatile. You can of course use it on your desktop Linux computer. [Plasma also has a mobile version](https://itsfoss.com/kde-announces-plasma-mobile/) that you can run on Linux-based smartphones like [Librem5](https://itsfoss.com/librem-linux-phone/) and [PinePhone](https://itsfoss.com/pinephone/).

The Plasma Bigscreen is a new project from KDE that aims to provide interface and features similar to what Smart TVs provide.

All you need is a [single board computer like Raspberry Pi](https://itsfoss.com/raspberry-pi-alternatives/) and a TV with HDMI port. Install Plasma Bigscreen on your device and connect it to your TV.

## Plasma Bigscreen features: More than just a media server

Though it may look like one at the first glance, but Plasma Bigscreen is not like Kodi and other [media servers for Linux](https://itsfoss.com/best-linux-media-server/). It’s more than that.

### Control with your regular remote

You don’t need a new specialized remote control. Thanks to [CEC](http://libcec.pulse-eight.com/), you can use your regular TV remote control.

### Voice control with open source Mycroft AI

Plasma Bigscreen takes advantage of the open source Mycroft AI project. With Mycroft built in to Bigscreen, you can use voice command to play content, check weather and control other aspects of your smart TV. You can further train this AI by teaching it new skills.

### Traditional desktop applications

Plasma Bigscreen delivers not only media-rich applications, but also traditional desktop applications redesigned to fit the Bigscreen experience.

### Free and open source software

The most important feature is that it is an open source project and it uses other open source technologies to give you the complete control over your data and your smart TV.

Since it is open source, I believe once it is released, there will be a few vendors providing it as a plug and play device.

## How to get Plasma Bigscreen?

Plasma Bigscreen is still in beta phase and there is no definite timeline for the stable release.

However, the beta version is also working good on devices like Raspberry Pi 4. Here’s a video by one of the developers working on this project.

If you have a Raspberry Pi 4, you can [download Plasma Bigscreen](https://plasma-bigscreen.org/#download-jumpto) beta version from its official download page and follow the steps [here](https://plasma-bigscreen.org/manual/) to install it.

Personally, I am really excited about it. I am going to take out some time and try it on my [Raspberry Pi 4](https://itsfoss.com/raspberry-pi-4/). What about you? Do you think the project has potential? Will you give it a try?
