How old is hdmi technology

Another variation on the many-to-one theme is the Multiviewer , which consolidates a number of video inputs on a single monitor. Multiviewers are found in broadcast control rooms and video surveillance systems.

No, an HDMI splitter takes one video signal and replicates it to multiple displays so each display shows the same image. This is known as "mirroring". Here are your options for extending your desktop:. A power surge is typically a brief increase in voltage due to, for example, an overloaded circuit, power outage or lightning strike. A surge protector detects excess voltage and safely diverts it through the building's grounding system so it doesn't damage connected equipment.

HDMI surge protectors are intended to supplement primary surge protection and are installed "in line" between a video source and display. Important: surge protectors do not provide two-way protection against power spikes. If you want to protect both source and display, you should install two surge protectors: one with its output facing the video source and one with output facing the display.

Do in-line surge protectors degrade the HDMI signal? All in-line surge protectors introduce a small impedance into the line and a capacitance across the line. An HDMI signal includes both video and audio, which is convenient because you need only one cable to connect a cable box, game console or streaming device to your television. But if you want to play audio through an older analog sound system that doesn't have HDMI support, you will need to separate the audio track from the video.

That's where an audio extractor comes in. Depending on the capabilities of the audio extractor, you may have the choice of compressed or uncompressed LPCM audio outputs, for example, 3.

With 8K TVs and cameras now readily available, first adopters are turning their attention to even higher resolutions, including 10K and 16K, and refresh rates above 60 Hz.

Bandwidth is the biggest barrier to higher resolutions and refresh rates. Ignoring all of the extra data layered on top of the video itself, the simple formula resolution x refresh rate x color depth adds up to a lot of bits which need to be moved from a video source to a display. An uncompressed 8K, bit color video signal at 60 Hz needs almost 50 Gbps of data bandwidth.

Since , one or two brands have been able to squeeze one or two features associated with the HDMI 2. Formally launched on November 28 , the v2.

Looking at the sort of new features HDMI 2. It also supports so-called Dynamic HDR, where extra scene by scene information is provided to displays to help them show their HDR pictures better. The trouble with HDMI 2. Guide: The best streaming sticks.

Much of this potential confusion is down to manufacturers deciding to support different data rates with their various HDMIs, where the data rate can dictate the level of HDMI 2. Look for some sort of itemised breakdown of which specific HDMI 2. Samsung has managed to get some HDMI 2. Since the arrival of HDMI 2. So if you just buy the cheapest HDMI cable you can find, it may not give you all the features you want.

Most HDMI cables are passive, and can pass their signals in either direction. Active HDMI cables, though, only send their video signal in one direction. Because they contain power boosters that amplify the signal coming from your source as they send it on its way. However, if you need to use a really long cable run likely 30 feet or more , an Active HDMI cable may make the difference between a data-intensive signal making it or not, as HDMI cables generally become less reliable the longer they are.

This protocol offers two-way communication between devices over a single HDMI connection. Since ARC was introduced in , it has become a very common standard, and you'll find it on virtually all TVs, soundbars and receivers sold in recent years.

Anything that works with the HDMI 1. First, you can connect your audio system with a single HDMI cable. Connect your soundbar to the TV using the designated ARC-capable port, and you can use it for every device that connects to the TV, including Blu-ray players, game consoles and other devices.

And it does that through the TV itself, instead of requiring a separate audio receiver. Second, you can run these connections through the soundbar itself, letting you shift the multiple HDMI connections from the TV to the soundbar without requiring any additional setup. This is especially helpful for instances in which your TV is wall mounted and you either don't have access to all of the HDMI ports or simply want a cleaner look with fewer cables running to and from the TV.

It also means fewer cables to install. Audio going to the TV from an antenna, for example, can also be output over HDMI and piped through the soundbar instead of just the TV's built-in speakers. This is especially important for smart TVs, for which streaming services deliver all content via Wi-Fi, with nothing to feed into a receiver.
