Introduction of Smart TV
A Smart TV is a television set or a TV device that integrates internet connectivity and interactive features alongside
traditional television functions. It represents a significant evolution in home entertainment technology, combining
television viewing with internet-based content and services.
The introduction of Smart TVs has revolutionized how people consume media, offering a wide range of features
and capabilities that enhance the viewing experience. Here’s an overview of the key aspects of Smart TVs:
1 Internet Connectivity: Smart TVs are equipped with built-in Wi-Fi or Ethernet ports that allow them to connect
to the internet. This connectivity enables users to access a variety of online content and services directly from
their TV screens.
2 Streaming Services: One of the primary features of Smart TVs is the ability to stream content from popular
online streaming services such as Netflix, Hulu, Amazon Prime Video, Disney+, and others. Users can access
a vast library of movies, TV shows, documentaries, and original content on-demand.

3 App Store Access: Smart TVs often come with their own app stores or platforms where users can download
and install additional applications. These apps may include gaming, social media, news, weather, sports, and
other entertainment options, expanding the functionality of the TV beyond traditional broadcasting.
4 Web Browsing: Smart TVs typically include web browsing capabilities, allowing users to surf the internet
directly from their TV screens. This feature enables access to websites, online shopping, social networking
sites, and other online resources.
5 Screen Mirroring and Casting: Many Smart TVs support screen mirroring and casting features, allowing
users to mirror the screen of their smartphones, tablets, or computers onto the TV display wirelessly. This
enables easy sharing of photos, videos, presentations, and other content with friends and family.

6 Voice Control and Smart Assistants: Some Smart TVs are equipped with voice recognition technology and
built-in smart assistants like Amazon Alexa, Google Assistant, or Samsung Bixby. Users can control their TVs,
search for content, adjust settings, and even control other smart home devices using voice commands.
7 Interactive Features: Smart TVs may offer interactive features such as interactive gaming, quizzes, polls, and
social media integration, enhancing user engagement and interactivity while watching TV.

diode (OLED), or quantum dot LED (QLED) panels that display images and videos.
2 Processor and Memory: Smart TVs contain processors (CPUs) and memory (RAM) to handle tasks such as
app processing, streaming, and interface navigation.
3 Connectivity Hardware: Smart TVs include Wi-Fi, Ethernet, and Bluetooth hardware for connecting to the
