In today’s pursuit of high-quality home entertainment,
we often hear terms like “TV set-top box,” “TV box,” “media box,” “IPTV box,” “OTT box,” “Streaming Media Streamer,” and “Streaming Media Player.”
These are all small devices that can connect to a TV, but their functions differ.
To understand these concepts, let’s start with 【TV set-top box】 and 【TV box】!
I. What is a TV Set-Top Box?
TV set-top boxes were originally created to solve the problem of receiving and decoding television signals.
Traditional cable TV, satellite TV, or terrestrial digital TV signals are transmitted to your home as encrypted or compressed digital signals, which the TV cannot directly recognize. The set-top box’s role is to receive these signals and decode and convert them into audio-visual content that the TV can understand and play.
1.1 Content Source
TV set-top box signals mainly come from cable TV operators or satellite TV service providers.
Content is typically a fixed list of channels, and users cannot install apps to expand the content.
1.2 Usage Model
Users need to pay a monthly or annual subscription fee to the service provider to watch channels.
Definition: Pay TV, live channel streaming, carrier-customized, single-function.
II. What is a TV Box?
TV Box is often mentioned alongside “network set-top box,” “smart TV box,” or “streaming media player.” However, the meaning of TV Box is broader; it is a product of the internet age.
A TV Box is essentially a simplified computer, usually equipped with a smart operating system (such as Android TV, Google TV, etc.), and connects to the internet via home Wi-Fi or a wired connection.
2.1 Content Source
Content comes almost entirely from the internet. Users can install various streaming media applications, such as Netflix, YouTube, Disney+, etc.
What to watch?
When to watch?
Completely up to the user.
2.2 Expandability
Users can freely install and uninstall apps from the app store, just like on a mobile phone. They can not only watch videos, but also play games, listen to music, and more, offering a rich array of functions.
2.3 Usage Mode
TV boxes are purchased as a one-time hardware purchase. Content viewing may involve subscribing to specific streaming services (such as Netflix). There are also smart TV boxes like the We2usat K3 Pro+, which come with five premium content apps, allowing users to freely watch popular sports live streams, US and international TV channels, and movies and TV series from various countries.
Definition: Smart system, online streaming media, application expansion, on-demand freedom.
