What is a smart tv?

A “smart” TV is primarily characterized by its connectivity and its intelligence in the form of computing power. Often also referred to as “Hybrid TV”, these models can call up numerous other functions via different interfaces that have usually been used on computers to date. To describe a Smart TV as a pure output device would be far too short-sighted, because the device now contains a full-fledged PC with a powerful processor. The most important interface to the outside is probably the connection to the Internet (broadband Internet). This is done via an integrated network connection or wirelessly with WLAN.

What interfaces does a Smart TV have?

A Smart TV should offer useful interfaces, for example for additional memory cards or different USB slots.​​​​​

A Smart TV should offer the following interfaces:

  • Triple Tuner: A triple tuner for the three formats DVB- T (antenna), DVB-C (cable) and DVB-S (satellite) is now standard for a Smart TV.
  • CI+ interface: A standardized one Interface that accepts and decodes a decoder card for additional chargeable channels.
  • Bluetooth: A Smart TV with a corresponding Bluetooth keyboard, a Bluetooth headphones or other input devices. Tip: When buying a Smart TV, make sure that the Bluetooth also supports audio output. This is not yet standard for many devices.
  • USB interfaces: Users can use a USB interface to connect a Smart TV with a USB stick or a USB Connect hard drive and use it as a recorder. USB recording is possible from digital channels, i.e. DVB-T/S/C.
  • HDMI CEC: The abbreviation CEC stands for Consumer Electronics Control and is a control function. Devices that are connected via an HDMI CEC interface can, for example, be operated using a single remote control.
  • HDMI ARC: HDMI ARC means that via the HDMI interface provides an audio return channel. This is z. B. important for connecting a Soundbar.

Tip: When buying a Smart TV, make sure that there are as many HDMI ARC/CEC and USB interfaces as possible.

What functions does a Smart TV have?

A Smart TV is characterized by features that go far beyond what a traditional TV offers. What they all have in common is interactivity.

  • HbbTV: A fundamental difference to conventional TV sets is the video text successor HbbTV. Thanks to an Internet connection, HbbTV is interactive and enables applications such as quizzes, for example.
  • Web browser: A major distinguishing feature of a Smart TV is the presence of an integrated web browser, with which users can surf web addresses.
  • Voice Assistants: Smart TVs are often compatible with the language assistants Alexa, Google Assistant or Bixby. Communication usually takes place via a microphone integrated in the remote control. If the language assistant is not already integrated in the TV, the user must e.g. B. First the Connect TV with Alexa.
  • AirPlay support: If the Smart TV supports Apple’s AirPlay standard, users can transfer content from Apple devices such as iPhone to a Smart TV.
  • DLNA support: Smart TVs that have a DLNA certification can also display content from smartphones or others DLNA-certified devices.
  • Mirror Cast, Chrome Cast: Other wireless transmission formats that allow users to play content from compatible devices such as Smartphones to a Smart TV.

Which HDR formats should a Smart TV be able to handle?

When it comes to HDR, there is often a lot of confusion among consumers because there are so many different formats on the market. HDR stands for High Dynamic Range, i.e. image content with a high dynamic range, also known as a high-contrast image. The higher the brightness value of a Smart TV, the better the HDR effect comes into its own. Owners of an OLED or QLED TV device benefit particularly well.​​​​​​

The aim of HDR is to display the image output on the Smart TV as faithfully as possible. For this purpose, when the source material is played back, HDR meta information about the image settings is sent, which contains the image values ​​of the original. The most important HDR formats include:

  • HDR10: HDR10 is a static basic format. This means that the image information is converted at the beginning of playback and remains the same throughout the film. The number 10 stands for 10-bit color depth.
  • HDR10+: The HDR format HDR10+ or ​​HDR10 Plus is a development by the TV manufacturer Samsung. The open standard can also be used by other manufacturers. HDR10+ is a dynamic HDR format, which means that the contrast and brightness values ​​are supplied for each film scene on the meta level and implemented by the TV.
  • Dolby Vision: Dolby Vision is also a dynamic HDR format developed by Dolby and for which TV manufacturers have to pay licensing costs. Dolby Vision allows up to 12 bits of color information and is particularly popular in Hollywood.
  • HLG: Hybrid Log Gamma (HLG) is an HDR format that can be used by TV broadcasters during live transmissions, e.g. B. at soccer or other sports events.
  • HLG+: The dynamic variant of HLG, also called HLG Plus.

Which sound formats are important for a Smart TV?

The same often applies to sound formats as to HDR formats: the more expensive the Smart TV, the better audio formats are available. A current Smart TV should support at least the formats DTS and Dolby Digital. Better still Dolby Digital Plus and Dolby Atmos.

The most important formats include:

  • DTS: If you want to enjoy your films and series with surround sound, should pay attention to the support of DTS Surround Sound on the Smart TV. It is a multi-channel sound technology that supports 5.1 home cinema systems, for example.
  • DTS-HD: With the DTS-HD standard, users can use the Restore studio sound almost 1:1.
  • Dolby Digital: The Dolby Digital sound format is also a multi-channel format whose patents have now expired and which is therefore supported by most Smart TVs.
  • Dolby Digital Plus: The audio format Dolby Digital Plus supports up to 7.1 channels and was developed, among other things, for the coding of multi-channel streaming and download content. Only uncoded stereo sound is available.
  • Dolby Atmos: A feature of Premium Smart TVs is the support of Dolby Atmos. The audio format allows the playback of 3D sound, as is also used in cinemas. The viewer gets the impression that objects move three-dimensionally in space. For example, a train that runs from the back left to the front right.
  • Dolby TrueHD: The same applies to Dolby TrueHD as to DTS-HD. Here, too, the original studio sound can be restored almost 1:1.
  • THX: THX is not an audio format, but a collection of standards that loses more and more importance. It defines requirements for loudspeakers, room illumination, spectator seating positions, etc.

What are the system requirements for a Smart TV?

In order for a Smart TV to be able to fully develop its range of functions, a broadband connection is absolutely necessary. If broadband Internet is not available, switching to a LTE flat rate is an alternative. If the WLAN or internet coverage at home is too weak, you can also set up a mesh WLAN with the help of a WLAN Mesh Sets help.

One ​​of the main areas of application of a Smart TV is video streaming from services such as Amazon Prime Video or Netflix.

Smart TV system requirements – HDMI interface

Should films and series with Prime Video and Netflix viewed on a Fire TV device must be connected to an HDMI port that supports HDCP 2.2. All other devices that are part of your home theater (e.g. HDMI receivers and soundbars) must also support HDCP 2.2.

Smart TV system requirement – Internet bandwidth for video -Streaming

In order to ensure trouble-free transmission of videos, the bandwidth should be at least 6Mbit/s with HD quality. The video streaming service Netflix recommends the following bandwidths:

  • 0.5 Mbit/s minimum bandwidth
  • 1.5 Mbit/s recommended Internet Bandwidth
  • 3.0 Mbit/s Recommended Internet Bandwidth for SD Quality
  • 5.0 Mbit/s Recommended Internet Bandwidth for HD quality
  • 25 Mbit/s Recommended Internet bandwidth for Ultra HD quality (4K UHD)

Amazon recommends an internet bandwidth of at least 15 Mbit/s for streaming in 4K Ultra HD.

Smart TV System requirement – ​​DVB-T/S/C tuner

Even if video streaming is becoming more and more popular, you should also pay attention to other sources. Cable connection (DVB-C) or a satellite system (DVB-S) are still often used for traditional linear television. Reception via a terrestrial antenna (DVB-T) is still possible.

So if you are planning to buy a Smart TV, you should find out about the im Smart Home inform existing connections. The easiest way is to use a variant with Triple Tuner, which then has a DVB-T(2), DVB-S(2) and DVB-C tuner on board. If a satellite signal is available as a reception source at home, a twin tuner offers real added value because it can receive two satellite signals at the same time. This means that one channel can be viewed and another recorded at the same time.

If in doubt, these can also be retrofitted in the form of a set-top box. The newer DVB-T2 tuner is backward compatible with a DVB-T tuner. The same applies to satellite receivers. Conversely, however, there is no compatibility. The respective further developments promise higher transmission rates and use different coding techniques.

What resolution do Smart TVs have?

In general, Smart TVs come in almost all sizes. The television sizes often start with a screen diagonal of 32 inches. Probably the most popular size at the moment is the 55 inch TV. A 32-inch TV usually offers Full HD resolution. From a TV size of 43 inches, current TVs provide a 4K UHD resolution.​​​​​

Smart TV resolution – 4K Ultra HD replaces HD resolution

In recent years the 4K UHD resolution has become more and more popular. Anyone who wants to buy a Smart TV that is larger than 32 inches will almost inevitably come across a 4K UHD Smart TV . HD content is upscaled to UHD resolution. Although this does not deliver as sharp an image quality as a native 4K resolution, it is still an improvement compared to Full HD.

The range of UHD/4K video material is also constantly growing and is available from different sources. Above all, the streaming services Netflix and Amazon should be mentioned, but the current generation of game consoles or selected 4K Blu-Ray media are also available.

Smart TV resolution – 4K UHD for photos

The display of photos on the TV is still underestimated but is becoming more and more popular. In particular, newer smartphones with their very good camera functions are increasingly replacing the digital camera. Thanks to mobile device transmission of content to the Smart TV, the high-resolution images from the mobile phone can then be conveniently viewed on the television.

Smart TV resolution – difference between 4K and Full HD

Full HD (also known as 1080p) stands for a resolution of 1920×1080 picture elements (pixels). The vertical pixels, i.e. the height of the screen, are 1080 pixels and in total you get around 2 million pixels on a Full HD television set. In contrast, 4K or UHD (Ultra High Definition) works with around 8 million pixels, i.e. 4 times as many. The UHD and 4K formats are often used the same thematically, with UHD having a resolution of 3840×2160 pixels in 16:9 format and 4K only appearing on digital cinema screens. A 4K resolution is only slightly wider than UHD, namely 4096 pixels with the same number of columns. In normal usage, however, the term 4K has also become commonplace for the UHD format. In any case, the result is a clearly detailed 1080p image in both cases and the difference is immediately visible.
