What is a Smart TV set-top box with Wi-Fi and why do you need one?

Prefix Smart TV with Wi-Fi - is a compact device that connects to the TV via HDMI and adds smart TV features to it. Unlike the built-in Smart TV modules in modern televisions, the set-top box operates autonomously: it has its own processor, memory, and operating system (usually based on Android or Linux).

The main tasks of the console:

• 📺 Video streaming - watching movies and TV series through Netflix, YouTube, KinoPoisk HD and other services.
• 🎮 Games - launching mobile games (for example, through Google Play Games) or cloud services like GeForce NOW.
• 🌐 Web surfing — Internet access via a browser (although this is not always convenient from the remote control).
• 📁 Media player — playback of movies, music and photos from a flash drive, external hard drive or over a local network.
• 🏠 Smart Home - control of devices via Google Home or Alice (if the set-top box supports voice assistants).

The main advantage of the set-top box over the built-in Smart TV is the ability to upgrade without buying a new TVEven if your TV was released in 2010, it still has HDMI-port, you will be able to watch 4K HDR- content via a set-top box (provided that the TV itself supports this resolution).

⚠️ Note: Some budget consoles (for example, Xiaomi Mi Box S or H96 Max) may not support AV1-codecs or Dolby Vision, which limits playback quality on some services. Check the model's specifications before purchasing.

How the set-top box connects to the TV and the Internet: a diagram of how it works

The set-top box functions as a standalone computer, feeding the TV a ready-made signal. Let's look at how this interaction works step by step:

1. Connecting to a TV — the set-top box connects to the TV via HDMI-cable (less often - through AV or SCART (for older models). In this case, the TV acts as a monitor.
2. Nutrition — the set-top box is plugged into a socket via an adapter (usually 5V/2A). Some models (for example, Apple TV 4K) require a more powerful power supply.
3. Internet connection — the set-top box can connect to the router via Wi-Fi (at frequencies 2.4 GHz or 5 GHz) or through Ethernet-cable (for stability).
4. Authorization in services — the user logs into accounts Netflix, YouTube, OKKO and other platforms directly on the console.
5. Content processing — the set-top box decodes video/audio streams and sends them to the TV in the optimal resolution (for example, it scales 1080p to 4K, if the TV supports upscaling).

It is important to understand that The set-top box doesn't just "transmit" the Internet to the TV — it downloads content itself, processes it, and only then displays it on the screen. Therefore, the smoothness of playback depends on its technical specifications (processor, memory, codec support).

If your router supports Wi-Fi 6, but the set-top box only works with Wi-Fi 4 (802.11n), the connection speed will be limited to ~150 Mbps. This may cause lag when browsing. 4K HDR-content. In such cases, it is better to use a wired connection (Ethernet).

Specifications: What to look for when choosing

Not all consoles are created equal. Here are the key parameters that affect performance and functionality:

Also pay attention to codec support:
