HDMI分配器是用于将多个设备连接(connect multiple devices)到单个源的设备。它通过从源（可以是蓝光播放器(BluRay Player)、Roku或机顶盒）获取HDMI视频输出并将(HDMI)HDMI信号分配到多个设备来实现这一点。
音频和视频被分成两个独立的流，同时馈送到不同的监视器(fed to separate monitors)或电视。
如果您的 AV 或电视接收器上没有足够的输入，并且想要将多台电视(TVs)连接到一个信号源，您可以使用HDMI分配器来分离HDMI信号。当您有太多电缆要交换时，这也是一种整理周围所有电线以获得更整洁空间的廉价方式，并保持您的装备有用和相关。
但是，要使用HDMI分配器，它必须与您要发送的分辨率兼容，并且应该能够很好地工作，因为大多数都没有。
HDMI分配器如何工作？(How Do HDMI Splitters Work?)
HDMI是高清视频的信号格式，随之而来的是各种用于修改、增强或调节信号的选项。HDMI分配器是拆分HDMI信号以将其发送到多个显示器的最简单和最通用的方法之一。
只需将其插入并将其设置在您的客厅或工作区中，即可轻松部署，以连接到源(connect to the source)并输出到多个设备。
例如，如果您有一个蓝光播放器，您可以将其插入分配器，该分配器已插入您的多台显示器，它们都将收到相同的全高清图片，具有与蓝光播放器相同的音频。射线(Blu-ray)播放器发出。
HDMI分配器从源设备获取信号并将相同的信号发送到其他显示器，例如蓝光(Blu-ray)播放器（源）和电视(TVs)（显示器）。
一些HDMI分配器兼作HDMI开关，它采用多个HDMI源设备，您可以在这些设备之间切换或选择，并将一根电缆发送到单个电视。
如果您使用HDMI分配器并发现它不能分割HDMI信号，这可能是因为高带宽数字内容制作(High-Bandwidth Digital Content Production)( HDCP ) - 媒体流媒体、(HDCP)电视(TVs)和电缆中内置的一项功能，可确保您没有在播放盗版内容。
HDCP通过在媒体流媒体和屏幕之间建立经过验证的连接来保护内容，加密信号以防止非法或未经授权的内容录制。
如果没有符合 HDCP 的设置，无论是HDMI分配器还是视频，都不会起作用，您最终可能会看到错误消息，而不是您尝试流式传输的内容。
分配器处理HDCP信号和数字握手，以读取和匹配每个设备预期的信号，从而减少设置失误和信号不兼容性。
不过，一些HDMI分配器可以规避HDCP限制。这是可能的，因为HDCP(HDCP)中的回退模式允许任何兼容的内容恢复到较低的分辨率并正常播放，其中设置不兼容HDCP 。
注意：(Note: )如果您打算将HDMI分配器用于合理使用应用，例如合法备份您的财产、在游戏时记录自己以及类似用途，则拆分HDMI信号并不违法。但是，如果您打算在未经授权的情况下使用它来复制和分发内容，则拆分HDMI信号是违法的。
最好的 HDMI 分配器购买
在寻找HDMI分配器时，请检查HDMI版本 1.3（a 或 b）和 1.4 分配器，因为它们提供一个输入和三个或四个输出。检查您想要的分配器是否带有电源适配器并提供大量能源以提高效率，是否有足够长的电缆来连接您的设备，其分辨率是否足以传输高质量的图形而不会失真。
分离器还应与您的设备兼容，价格合理，并提供广泛的保修，以防万一发生任何意外，以便您在可能的情况下对其进行维修或更换。

How Do HDMI Splitters Work & Best Ones To Buy
An HDMI splitter iѕ a device used to connect multiple devices to a single source. It does this by taking the HDMI video output from the source, which can be a BluRay Player, Roku, or cable box, and distributing the HDMI signal to multiple devices.
The audio and video are split into two separate streams, which are fed to separate monitors or TVs at the same time.
If you don’t have enough inputs on your AV or TV receiver, and want to connect multiple TVs to a single source, you can use an HDMI splitter to split the HDMI signal for this purpose. It’s also an inexpensive way of sorting out all the wires around you for a neater space when you have too many cables to swap, and keeping your gear useful and relevant.
However, to use an HDMI splitter, it has to be compatible with the resolution you want to send, and it should be able to work well because most of them don’t.
How Do HDMI Splitters Work?
HDMI is the signal format for HD video, and with it came various options for modifying, boosting or regulating the signal. An HDMI splitter is one of the simplest and most versatile ways of splitting an HDMI signal to send it across multiple displays.
It’s easy to deploy by just plugging it in and setting it up in your living room or workspace to connect to the source and output to multiple devices.
For example, if you have a Blu-ray player, you can plug it into the splitter, which is plugged into your multiple displays, and they’ll both receive the same picture in full-HD, with the same audio that the Blu-ray player sends out.
HDMI splitters take the signal from your source device and send the same signal to other displays, as in the case of the Blu-ray player (source) and the TVs (displays).
Some HDMI splitters double as HDMI switches, which take multiple HDMI source devices that you can switch or choose between and send one cable to a single TV.
If you get an HDMI splitter and find that it doesn’t split HDMI signals, it’s probably because of the High-Bandwidth Digital Content Production (HDCP) – a feature built into media streamers, TVs, and cables that ensures you’re not playing pirated content.
HDCP protects content by establishing a verified connection between your media streamer and the screen, encrypting the signal to prevent illegal or unauthorized content recording.
Without a HDCP-compliant setup, whether it’s the HDMI splitter or the video, nothing will work and you’ll likely end up seeing error messages instead of the content you’re trying to stream.
The splitter handles HDCP signals and digital handshaking to read and match signals expected by each device so there are less setup mishaps and signal incompatibilities.
Some HDMI splitters can circumvent the HDCP restriction though. This is possible because of the fallback mode within HDCP that allows any compliant content to revert to a lower resolution and plays normally, where the setup is non-HDCP-compliant.
Note: If you’re going to use the HDMI splitter for fair-use applications like making legal backups of your property, recording yourself while gaming, and similar uses, it’s not illegal to split an HDMI signal. However, if you plan on using it to copy and distribute content without authorization, it’s illegal to split the HDMI signal.
Best HDMI Splitters to Buy
When looking for an HDMI splitter, check for HDMI version 1.3 (a or b) and 1.4 splitters as they offer one input and three or four outputs. Check whether the splitter you want comes with a power adapter and offers a high amount of energy to be efficient, has a long enough cable to connect your devices, and its resolution is adequate enough to transmit high-quality graphics without distortion.
The splitter should also be compatible with your devices, be reasonably priced, and comes with an extensive warranty that covers it for a long time in case of any mishaps so you can get it repaired or replaced if possible.
The best splitters let you connect and transmit audio and video over different devices, plus they’re HDCP-compliant and durable. Below are some of the best, high-rated ones you can buy.
This HDMI splitter is practical, stylish, and offers a lot more than many other HDMI splitters on the market.
It features status indicators at the front, while the input port, outputs, and power supply connector at the back so it’s easier to track which displays you’re using. This is unlike other splitters that place these on the side or front of the device. There are also open side vents that keep it from overheating.
To setup the device, plug the HDMI input and output sources into the splitter and it’ll transmit the signal to your devices.
It offers High Definition resolutions for watching movies or gaming, but can also accommodate lower resolutions if you have an older screen model. It also offers support for all audio formats available.
This HDMI splitter lets you connect up to five HDMI input devices to a single output display so you can reduce the wire clutter on your space for seamless transition.
It supports 4K 30hz resolution, 1080p, and immersive 3D content so you can experience your favorite movies or games in crisp and crystal-clear quality.
The device’s body is built with hybrid aluminum and all its ports are at the back with front status lights for power. Plus, it automatically switches depending on the active input so you can enjoy your viewing without setup hassles, but you can still switch manually from the Infrared (IR) remote.
Kinivo offers a one-year warranty with a lifetime of support though this is limited to the U.S.
This reasonably priced HDMI splitter may not have well organized ports like the others mentioned here, but it’s a top pick for value as it gives you five extra HDMI ports and an accurate IR remote you can use to switch between them.
It works well with several devices, and supports resolutions of up to 1080p and 3D, plus HDMI version 1.3b and HDCP 1.1.
A one-year warranty is available plus customer support via email.
This is a 1×2 HDMI splitter so it offers less in terms of output, but it’s ideal when you want to split an HDMI signal to send large amounts of data over different platforms at a go.
It’s durable, efficient, and provides extensive support for a variety of audio formats like Dolby-AC3 and TrueHD, or LPCM, among others.
Among the features you’ll find on the OREI HDMI splitter include a bulky duty metal enclosure that protects the device and helps with heat dissipation, plus a plug-and-play mechanism that doesn’t need any technical knowledge or experience to on your part to setup and use.
It’s economical, operates with high-quality resolution display, and can be connected for Full HD output, though it doesn’t necessarily meet or suit everyone’s needs.
