World’s biggest 4K widescreen TV probably costs more than your house


C Seed isn’t a household name in the world of electronics, which isn’t a complete surprise given that not many households could afford the company’s products. A perfect case in point is the new C Seed 262, which with a diagonal screen size of 262 in (6.65 m) is the world’s largest 4K widescreen TV – and it’s got a suitably large price to match.


Vienna-based C Seed is no stranger to big, expensive TVs. It took out a Red Dot “Best of the Best 2012” design award with its 201-inch outdoor LED TV. The result of a collaboration with Porsche Design, this monster rose out of a ground recess at the touch of a button on its remote.

The new 262 isn’t built to withstand the outdoor elements, but is also the result of a collaboration – this time with L-Acoustics, which is responsible for the TV’s onboard sound system that comprises six or 10 high-end speakers, depending on which press materials you look at.

But there’s no confusion about that gargantuan screen. Its 262-in (6.65 m) diagonal length gives it a width of 20.16 ft (6.14) m and height of 8.44 ft (2.57 m), so it’s at a size where the 4096 x 1716-pixel resolution will actually make a noticeable difference. The display also boasts black LED technology providing a 5,000:1 contrast ratio and pumps out 800 nits of brightness.


The C Seed 262 UHD TV’s 262-in (6.65 m) diagonal length gives it a width of 20.16 ft (6.14) m and height of 8.44 ft (2.57 m)

C Seed has also managed to almost completely eliminate the bezel on three sides, with the only blemish a black bar that extends 6.1 in (15 cm) from the bottom and runs the length of the screen. For the full cinema experience, the TV comes with a motorized custom fabric cover that folds away at a push of a button on the remote, as well as a 4K media server built in.

If you have a wall big enough, you’ll need some pretty strong brackets to hold the TV in place as it weighs in at a hefty 1,764 lb (800 kg). C Seed also offers full installation, for a fee of €35,000, US$38,500 on top of the purchase price of €490,000, US$549,000, which would bring the total cost to well over half a million dollars.

If your bank balance can handle it, the C Seed 262 is available now.

Do Video Signals Need to Be Routed Through Home Theater Receiver?


Do Video Signals Need to Be Routed Through a Home Theater Receiver?

With home theater, the role of the receiver (which is really a combination of a preamplifier and power amplifier) has changed significantly over the course of the past decade.

It used to be that the receiver took care of all the audio switching and processing, as well as providing power to the speakers. However, with the increased role of video, A/V or home theater receivers, as they are now referred to, also provide video switching and, in many cases, video processing and upscaling.

However, does that now mean that you are required to connect all your video source signals (such as VCR, DVD, Blu-ray Disc, Cable/Satellite, etc…) to your home theater receiver?

The answer to this question really depends on the capabilities of your home theater receiver and how you want your home theater system organized.

You can bypass the home theater receiver for routing video signals if you want to, and instead, connect the video signal from your source device directly to your TV or video projector and then also make a second audio-only connection to your home theater receiver. However, there are are some practical reasons why you might want to route both your video and audio signals through a home theater receiver.


First off, it can be more convenient to send the video signal through your receiver, as a receiver can control all the source switching for both audio and video.

In other words, instead of having to switch the TV to proper video input that your video source component is connected to, and then also having to switch the receiver to the proper audio input, you can do it in one step if both video and audio are able to go through the home theater receiver.

Video Processing and HDMI

Also, if you have a home theater receiver that has built-in video processing and upscaling for lower resolution analog video signals, routing your video sources through the receiver can provide some advantages there as well, as the processing and scaling feature of the home theater receiver may be able to provide a cleaner video signal going to the TV than if you connected analog video source directly to the TV.

Reducing Cable Clutter

However, an even better reason to route video signals through your home theater receiver is when you are using a DVD player or Blu-ray Disc player in your setup that provides HDMI connections, and the receiver also has HDMI connections with the ability to access, decode, or process audio signals embedded in the HDMI signal. Since HDMI carries both audio and video signals using a single cable, you simply connect the HDMI cable from your source component through your receiver for both audio and video using the one HDMI cable.

Not only does HDMI provide desired access to both audio and video signals, but reduces your cable clutter between the receiver the source device, the receiver, and the TV, since all you need is one HDMI connection between the receiver and the TV or video projector, instead of having to connect a video cable from your source to the TV or video projector and also connect a separate audio cable to your home theater receiver.

The 3D Factor

However, there is one exception to all of the above – 3D. Just about all home theater receivers manufactured beginning in late 2010 going forward are 3D compatible. In other words, they can pass 3D video signals from a 3D source device to a 3D TV or video projector via HDMI ver 1.4a (or higher) connections.

So, in that case, you can simply route your 3D and audio signals via a single HDMI cable through your receiver to a 3D TV or 3D video projector.

However, if you have a home theater receiver that does not offer 3D pass-through capability, you will have to connect the video signal from your 3D source to your TV or video projector directly, and then also make a separate audio connection to your non-3D compliant home theater receiver. For details for one example, refer to my illustrated article: How to Connect a 3D Blu-ray Disc Player to a non-3D Home Theater Receiver.

The 4K Factor

In addition to 3D, another thing to take into consideration with regards to passing video through a home theater receiver is the implementation of 4K resolution video.

With HDMI ver 1.4, home theater receivers started have limited ability to pass-through 4K resolution video signals (up to 30fps), but the introduction of HDMI ver 2.0 in 2013 enabled 4K pass-through capability for 60fps sources, and then again, in 2015, the introduction of HDMI ver 2.0a also provided the ability to pass HDR and Wide Color Gamut video signals.

What all of the above “techie” stuff regarding 4K means for consumers is that just about all home theater receivers made in 2016 going forward incorporate HDMI ver2.0a, which means full compatibility for all aspects of 4K video signal pass-through available now, and for the near future. However, for those that purchased home theater receivers between 2010 and 2015, there are some compatibility variations.

If you have a 4K Ultra HD TV, and 4K source components (such as a Blu-ray Disc player with 4K upscalingUltra HD Blu-ray Disc player, or 4K-capable media streamer) – consult your TV’s, Home Theater Receiver, and source components’ user manuals or online product support for information on their video capabilities.

In other words, if your 4K Ultra HD TV and source component(s) are fully equipped with HDMI ver2.0a and your home theater receiver is not, check your source components to see if you can connect them directly to your TV for video and make separate connection to your home theater receiver for audio, just as in the case of 3D.

Just keep in mind that making a separate video and audio connections may also affect what audio formats your home theater receiver will have access to.

However, unlike 3D, even if your home theater receiver is not compatible with all aspects of the latest 4K Ultra HD specifications, it will pass-through those aspects that it is compatible with, so users will still see some benefit if you still want to connect your 4K video sources to a home theater receiver that is equipped with HDMI ver1.4.

Capabilities and Preference

Whether you route both audio and video signals through a home theater receiver really depends on what the capabilities of your TV, home theater receiver, Blu-ray Disc/DVD player, or other components are, and what is most convenient for you.

My suggestion is to decide how you want to organize the audio and video signal flow in your home theater setup and, if needed, purchase a home theater receiver that best fits your preferences in that regard.

TIP: When looking for a home theater receiver that can consolidate both your audio and video connections for both analog and HDMI sources, look for units that offer analog-to-HDMI video conversion (converts analog video signals to HDMI with no further processing) or analog-to-HDMI video upscaling (converts analog video signals to HDMI and further processes video to match the native resolution of an HDTV or 4K Ultra HD TV).

Dolby Atmos FAQ’s



Q: What is Dolby Atmos?

Dolby Atmos® is a revolutionary new audio technology that transports you into extraordinary entertainment experiences.

  • Fills your room with captivating sound
  • Sound comes from all directions, including overhead, to fill the room with astonishing clarity, richness, detail, and depth.
  •  Puts sounds into motion all around you
  • The specific sounds of people, music, and things move all around you in multidimensional space, so you feel like you are inside the action.
  • Delivers the full impact of the artist’s work
  • Artists have amazing new capabilities to tell their stories, accent their games, or perform their music to achieve the greatest expressive impact.
  • Moves your mind, body, and soul
  • Sound excites your senses and inspires your emotions, flowing around you and connecting with you to create a more profoundly moving experience.

How does Dolby Atmos audio work?

Until now, cinema sound designers have had to mix independent sounds together into channels for soundtrack creation. A discrete sound, such as a helicopter, has been assigned to an individual channel rather than precisely to where it would occur naturally in the scene. While a sound can move across channels, there’s no height dimension. For example, you might hear the helicopter from a side channel and not above you. This approach limits your audio experience because it can’t come close to matching the way you hear in real life, with sounds coming from every direction.

Dolby Atmos is the first home theater system that is based not on channels, but on audio objects. What is an audio object? Any sound heard in a movie scene—a child yelling, a helicopter taking off, a car horn blaring—is an audio object. Filmmakers using Dolby Atmos can decide exactly where those sounds should originate and precisely where they move as the scene develops.

Thinking about sound in this way eliminates many of the limitations of channel-based audio. In a channel-based system, filmmakers have to think about the speaker setup: Should this sound come from the left rear surrounds or the left side surrounds? With Dolby Atmos, filmmakers just have to think about the story: Where is that yelling child going to run? How will the helicopter move overhead after takeoff? The Dolby Atmos system, whether in the cinema or a home theater, has the intelligence to determine what speakers to use to precisely recreate the child’s movement in the way the filmmakers intend. They can now precisely place and move sounds as independent objects in multidimensional space, including anywhere overhead, so you can hear them as you would naturally.

A Dolby Atmos home theater is also far more flexible and adaptable than channel-based home theater. In a channel-based system with channel-based content, the number of playback speakers is fixed: a 7.1 system consisting of seven speakers and one subwoofer is used to play 7.1 content. Additionally, there is no height information in the content. With Dolby Atmos, in contrast, you have amazing flexibility: the format provides even richer, more detailed sound by rendering to overhead or height speakers and/or to more than seven speakers at the listener level. As you add speakers, a Dolby Atmos enabled receiver will use them to create even more fantastic, immersive audio.

With the revolution in audio that is Dolby Atmos, sound designers are freed from channel restrictions. Sounds flow above and around you in step with the visuals, bringing a new sense of height and reality to your listening experience. Dolby Atmos helps weave the audio story to match what’s happening on the screen. It puts you in the middle of the action—in ways you have never experienced before.

Q: What is the difference between Dolby Atmos in the cinema and Dolby Atmos in the home?

The cinema, with its giant screen and massive sound system, will always be the reference for the ultimate entertainment experience. While home theaters have fewer speakers, the Dolby Atmos home experience is extremely powerful. It combines traditional home theater speaker layouts with many new possible speaker positions, including either ceiling-mounted speakers or new Dolby Atmos enabled speakers that reproduce sounds coming from above you. The impact of either in-ceiling or Dolby Atmos enabled speakers is breathtaking; your room fills with realistic, multidimensional sound that places you directly in the center of the entertainment experience.

Q: How does Dolby Atmos cinema content transition to home theaters?

The Dolby Atmos experience in the cinema is so powerful and flexible because of its revolutionary use of audio objects. To deliver the full object-based soundtrack to home theaters, Dolby developed new home authoring tools and new encoding methods that take into account the spatial information of the sound objects to efficiently encode them in Dolby® TrueHD and Dolby Digital Plus™. This spatial coding is not a channel-based, matrix-encoding system like Dolby Pro Logic® II or Dolby Pro Logic IIz. Instead, this fundamentally new coding technique allows all the audio objects created for the cinema to be used in the home theater. Nothing is lost.

Initially, home theaters will be able to play Dolby Atmos content on Blu-ray™ discs or through streaming video services. No matter the source, when a Dolby Atmos stream is fed to a Dolby Atmos compatible A/V receiver, the receiver will render the object-based audio to your home theater’s unique speaker configuration to precisely recreate the sound the filmmakers intended. Because the object-based audio mix is delivered to home theaters, Dolby Atmos has the ability to adapt to extremely diverse speaker setups, from systems with five speakers on the floor and two speakers producing overhead sound to Dolby Atmos supersystems with 24 speakers on the floor and 10 overhead speakers.

Q: Who is creating content, such as movies, for Dolby Atmos in the home?

Globally, more than 100 cinema blockbusters have been released featuring Dolby Atmos soundtracks since 2012, and many more are on the way. Major Hollywood studios are partnering with Dolby to create home video versions of current box office releases—and previously released favorites—for release in 2014. In addition to global studio partnerships, Dolby is partnering with game and music content creators to take advantage of Dolby Atmos technology for future home theater use.

Q: What home setup do I need to experience Dolby Atmos?

To experience this sound revolution, you’ll need a way to play or stream Dolby Atmos content, and to create your own Dolby Atmos home theater environment.

Options to Play or Stream Content

  1. You can play Dolby Atmos content from a Blu-ray Disc™ through an existing Blu-ray Disc player. Be sure you have a player that’s fully compliant with Blu-ray specifications.*


  1. You can stream content from a compatible game console, Blu-ray, or streaming media player.

In both cases, be sure to set your player to bitstream output.** Note that Dolby Atmos is compatible with the current HDMI® specification (v1.4 and later).

You then have several options for configuring your home playback system.

You’ll be able to assemble your own system from a wide range of available A/V components, starting with an A/V receiver (AVR) or pre-processor that supports Dolby Atmos. Many leading AVR manufacturers are introducing products in 2014 that support Dolby Atmos for the home. Several companies will offer complete home- theater-in-a-box solutions that support Dolby Atmos. These systems offer you the benefits of extraordinary Dolby Atmos sound together with the convenience and simplicity of an all-in-one system.

Watch for announcements throughout the year.

* You will not need to replace your Blu-ray player as long as it fully conforms to the Blu-ray specification. Current-generation Blu-ray players, and most older players, are compatible. You should check with the Blu-ray player manufacturer if you encounter problems. Some Blu-ray players default to secondary audio, a playback mode where third party content is mixed with the primary soundtrack and output as a Dolby Digital signal. Be sure to turn this feature off to insure decoding and playback of Dolby Atmos content by your AVR.

** Decoding and rendering of Dolby Atmos content is managed entirely by the A/V receiver. To properly pass the Dolby Atmos audio to the AVR, source devices must be connected to the AVR via HDMI and set to audio bitstream out.

Q: I already have a home theater. Do I have to replace all of my current speakers to build a Dolby Atmos system?

No. Many people now have 5.1 or 7.1 systems with a subwoofer and either five or seven speakers positioned at or about at ear level. Many of these speakers will work without a problem in a Dolby Atmos system.

However, overhead sound is a vital part of the Dolby Atmos experience. Many current home theaters aren’t capable of producing overhead sound, but there are a number of options for adding this capability to any room.

Q: How do I get sound coming from above?

The obvious answer is to install speakers in the ceiling. Most conventional ceiling speakers will work in a Dolby Atmos home theater.

But installing ceiling speakers may not be possible or desirable for you. Installing speakers in or on your ceiling and running the necessary wiring can be expensive and time consuming. If you rent your home, the property owner may not allow it. And if your ceiling is made of a material such as concrete, plaster, or brick, installing speakers in the ceiling is impossible. Finally, you may not like the look of overhead speakers.

Q: How can I get overhead sound if I don’t mount speakers in my ceiling?

Use speakers equipped with Dolby Atmos enabled technology. Through our knowledge of psychoacoustics and sound physics, we’ve developed speakers that can create overhead sound even though they’re only a few feet off the floor. These speakers fire sound upward, where it reflects off the ceiling to produce an incredibly lifelike recreation of overhead sound—you really have to hear them to believe them.

You will be able buy integrated Dolby Atmos enabled speakers that include both traditional forward-firing speakers and upward-firing speakers in one speaker cabinet. (Those speakers have two sets of posts, one for the traditional speaker and one for the upward-firing Dolby Atmos enabled speaker.)

But if you already have conventional speakers you like, you can simply buy Dolby Atmos enabled add-on speaker modules. These include only the upward-firing speakers. You can put the add-on modules on top of your current speakers or on another nearby surface.

Q: Will Dolby Atmos enabled speakers work in my room?

Dolby Atmos enabled speakers can produce an incredibly accurate Dolby Atmos experience in many kinds of rooms. You’ll get the best sound if your ceiling is flat (not vaulted or angled) and made of an acoustically reflective material, such as drywall, plaster, concrete, or wood.

While we designed the technology for rooms with ceiling heights of 8 to 9 feet (2.4 to 2.7 meters), our testing indicates that you can still hear incredible Dolby Atmos sound in rooms with ceilings as high as 14 feet (4.3 meters), though the effect may become more diffuse in rooms with higher ceilings.

Recessed lighting fixtures, chandeliers, crown molding, and heating or air conditioning vents in your ceiling do not noticeably interfere with the Dolby Atmos experience.

What is the smallest setup that Dolby recommends? What is the largest?

Because audio that originates from overhead is a key contributor to the Dolby Atmos experience, Dolby recommends using at least two speakers to generate overhead audio elements. This gives the minimal ability to move audio from left to right above the listener. The addition of four or more speakers to generate overhead audio elements provides the ability to move audio left to right and front to back above the listener. This provides greater precision to the Dolby Atmos experience.

For high-end home theaters, a 7.1.4 system (a traditional 7.1-channel-based layout with four overhead or Dolby Atmos enabled speakers) will provide a great listening experience. That being said, Dolby Atmos can support home theater systems with up to 34 speakers, in a 24.1.10 configuration: 24 speakers on the floor and 10 overhead speakers.

However, Dolby Atmos content is not tied to any specific playback configuration. Whether you have a full 7.1.4 system or a 5.1.2 system, your receiver will get the same content and play it back in a way that takes full advantage of your specific setup.

Q: If Dolby Atmos allows me to add more speakers, why do I see A/V receivers with just 11 channels?

Many hardware partners are building or planning to build Dolby Atmos enabled A/V receivers and speakers. Those partners decide what product configurations make the most sense for their customers. But Dolby Atmos for the home is almost unlimited. One of our hardware partners is planning to release an A/V receiver with 32 channels.

Q: If this is not a channel-based system, why are there predefined speaker positions?

While the Dolby Atmos algorithm is capable of rendering audio to virtually any speaker position, we defined 34 designated positions for speakers on the floor and overhead to simplify the setup process. By using these predefined positions, you can more easily configure your system.

We also defined a few “reference” speaker configurations to ensure that early customers could have a great experience while having the option to keep most of the equipment they already have. Among those reference setups are the 5.1.2 configuration, which involves adding two ceiling or Dolby Atmos enabled speakers to a traditional 5.1 system, and the 7.1.4 configuration, which starts with a traditional 7.1 system and adds four ceiling or Dolby Atmos enabled speakers. These configurations also ensure that you can play content mixed in legacy channel-based audio.

But we believe this is just the beginning. Because the Dolby Atmos object -based audio system is so adaptable, you can use many other speaker configurations. No matter what system you build, the Dolby Atmos format and system will adapt itself to output the best audio experience possible.

Q: How will I get Dolby Atmos movies?

We wanted to ensure that entertainment fans could get Dolby Atmos movies in the same ways they get movies now, on Blu-ray Disc or through streaming video services. We invented new scalable algorithms and extensions to Dolby TrueHD, our Blu-ray format, and Dolby Digital Plus, which is used by leading streaming video providers. Both formats now support Dolby Atmos sound, meaning that you’ll be able to play Dolby Atmos movies from your Blu-ray player or through your digital media adapter.

Q: Should I buy Dolby Atmos content even if I don’t have new equipment?

The Dolby Atmos format was designed to be backward compatible, so it will play on both new and existing hardware platforms. We recommend you purchase the Dolby Atmos version of content whenever that is available. In the future, upgrading your equipment to Dolby Atmos capable products will unlock the ultimate experience from Dolby Atmos content. In the meantime, you will get a great surround experience from traditional channel-based systems.

Q: What if I build a Dolby Atmos system but want to play content that isnt in Dolby Atmos?

A Dolby Atmos home theater can play any stereo, 5.1, or 7.1 content. Using the Dolby surround upmixer function in Dolby Atmos enabled AVRs, you can choose to have our technology automatically adapt that channel-based signal to use the full capabilities of your new system, including your overhead speakers, ensuring that you hear realistic and immersive sound.
