Televisiot

Televisiot are electronic devices that provide picture and sound by receiving, processing, and displaying video signals. They traditionally function as television receivers, but many modern models are smart TVs that stream content over the internet. A television generally combines a display panel, a video decoder, tuners for broadcast signals, speakers, and multiple input/output interfaces.

Historically, televisions used cathode-ray tubes and analog broadcasting. Flat-panel technologies such as LCD and plasma emerged in the late 20th century, with LED-backlit LCDs becoming dominant in the 2000s. OLED and other display technologies followed, offering higher contrast and faster response. Over time, resolutions increased from standard definition to HD, 4K, and now 8K in some models.

Today, televisiot vary by display technology, size, and features. Most include built-in tuners for terrestrial, cable, or satellite signals and support regional digital standards (for example DVB-T/T2, DVB-C, DVB-S/S2 in Europe, ATSC in North America). Smart TV platforms provide apps for streaming, web browsing, and control via Wi-Fi or Ethernet. Common interfaces include HDMI, USB, and sometimes Bluetooth. Many models support HDR, wide color gamut, and gaming-oriented features such as low-latency modes.

Other considerations include energy efficiency ratings and standby power, as well as price differences driven by size, panel technology, and included smart features. Televisiot are central to home entertainment, serving as primary displays for video content, gaming, and information in living rooms and bedrooms.
