Als je HDMI kabel voor 2009 is gemaakt, dan is de kans groot dat deze kabel geen ARC ondersteunt.
It wasn't until 2009 that the HDMI ARC protocol was added to the spec sheet. It was introduced as part of HDMI version 1.4 and has been part of the specification ever since.
If an HDMI connector is labeled with “HDMI ARC” or “ARC,” the TV supports it. Additionally, if your TV was made after 2009, it's likely that it will have HDMI ARC. Determining if your TV has HDMI ARC capabilities is relatively simple to do.
What Is HDMI eARC? In 2019, HDMI 2.1 was released with a new feature called eARC (enhanced audio return channel). This advancement has a higher bandwidth, giving you better audio quality and support for more immersive audio formats, such as uncompressed surround sound and Dolby Atmos.
While a regular HDMI connector is only able to transmit audio signals or video images, ARC has an added function that allows you to transmit audio signals from a TV back to the source, like a receiver or soundbar.
ARC has been supported since HDMI version 1.4 and by almost every TV. It makes it even easier to connect a home cinema system to the television. Thanks to HDMI ARC, a device can both receive audio signals from a single source and send them back via the same cable.
HDMI Audio Return Channel (ARC) is a particularly useful feature that was added to the HDMI 1.4 standard in 2009. ARC is an additional audio connection intended to replace external cables between the TV and the A/V receiver, or active speaker system, to simplify setup.
eARC stands for Enhanced Audio Return Channel. It's an improved version of ARC (regular Audio Return Channel).
In this HDMI ARC vs optical comparison, our experts conclude that the HDMI ARC is the better option and will produce better sound quality than the optical. HDMI ARC cables have video support and support higher sound resolutions, which optical cables don't.
The eARC is a feature implemented in the latest HDMI 2.1 specification, the biggest advantage is that it exceedingly improves bandwidth and speed. This allows you to transmit high-quality audio from your TV to your Soundbar or AV receiver and is compatible with the high bitrate formats Dolby Atmos and DTS.
What to do if my TV doesn't have an HDMI port labelled ARC? You can use an Optical Audio cable or Aux cable to connect the sound bar to the television.
If the TV has no ARC label on its HDMI ports, connect the HDMI cable to any HDMI ports on the TV and to the HDMI OUT (ARC) on the home theatre system or home audio system. Then connect an optical cable to the optical output port of the TV and the DIGITAL IN (TV) port on the home theatre system or home audio system.
In case of no HDMI audio return channel, then the next best thing to do is connect your TV to the soundbar using Bluetooth. Make sure that your TV has a bluetooth transmitter, then pair the TV with the soundbar. If your TV doesn't support bluetooth, then the next best option is to use a digital optical cable.
Check the HDMI connections on the back of your TV, soundbar, or receiver. If the HDMI port has ARC, it should be marked as such. Both your TV and the soundbar or receiver must have ARC for it to work. Note the tiny ARC label on the HDMI Out of this receiver.
HDMI ARC is supported in HDMI 1.4 and newer HDMI versions, while eARC is only supported in HDMI 2.1 cables. Since ARC is part of the standards and specifications of those HDMI versions, there are no different HDMI cables specifically with or without ARC support.
The increased bandwidth also brings with it support for the new eARC standard, affording you greater audio format compatibility. Just make sure all your devices support HDMI 2.1 and that you're using a HDMI 2.1 “ultra-high-speed” cable to take full advantage of all these great features.
Not all HDMI cables can let you experience the full capacity of eARC. Some HDMI cables do not have enough bandwidth to carry high-frame-rate video and high-bit-rate audio channels. However, high-speed HDMI cables with Ethernet are enough to support eARC, just like the next generation Ultra-High-Speed HDMI Cables.
Both cables can be had pretty cheap. The biggest difference is that HDMI can pass higher-resolution audio, including the formats found on streaming services such as Dolby Atmos and DTS HD Master Audio. These formats can't be transmitted across optical. In terms of simplicity, HDMI also passes video signals.
HDMI ARC supports different audio formats like PCM (2 channel), Dolby Digital (up to 5.1 channel) and DTS Digital Surround (up to 5.1 channel). In comparison, eARC supports the latest high-bitrate audio formats up to 192kHz, 24-bit, and uncompressed 5.1 and 7.1, and 32-channel uncompressed audio.
Most Dolby Atmos audio can be played through HDMI-ARC using the Dolby Digital Plus codec. HDMI-eARC is required to play lossless Dolby Atmos audio using the Dolby TrueHD codec.
Stream from all your favourite services, and feel like you're inside the song with support for the highest resolution formats, including Dolby Atmos Music. "When developing a soundbar, we treat music and home cinema equally.”
As a result, with an eARC channel, you can enjoy the depth of movie-theatre-quality surround sound via formats such as DTS:X and DOLBY ATMOS.
Now, the Enhanced Audio Return Channel (eARC) can transport uncompressed and full-resolution audio over HDMI 2.1 connections. As a result, you can enjoy Dolby Atmos sound from the integrated TV apps or listen to untouched High Definition or 3D sound from all devices connected to your TV via HDMI.
Most soundbars and TVs have an HDMI port. Keep in mind you need to use an HDMI ARC or eARC cable and port. If you don't have this, you'll need an optical cable in addition to an HDMI cable. With an HDMI 2.0b cable, you can transmit the sound of your television to your soundbar.
HDMI 2.1a features Enhanced Audio Return Channel (eARC) which is an advancement over the previous Audio Return Channel (ARC). eARC simplifies connectivity and provides greater ease of use for multiple components discovery and audio optimization.
