What is a built-in converter in a TV, and what is its purpose?
A built-in converter in a TV is an electronic component that allows the television to receive and decode broadcast signals, such as over-the-air (OTA) signals or cable TV signals, without the need for an external device. The converter’s primary purpose is to convert the received signals into a format that the TV can understand and display.
In the past, TVs relied on external devices, such as set-top boxes or digital converter boxes, to receive and decode broadcast signals. However, with the advent of modern TVs, manufacturers began to integrate converters directly into the TV, eliminating the need for external devices. This integration has made it easier for consumers to access a wide range of channels and programming without the clutter of additional devices.
When did TVs start getting built-in converters?
The integration of built-in converters in TVs began in the early 2000s, as the television industry transitioned from analog to digital broadcasting. In the United States, the Federal Communications Commission (FCC) mandated that all TVs sold after March 1, 2007, include a built-in digital tuner, which is a type of converter that allows TVs to receive digital broadcast signals.
As the digital TV transition progressed, TV manufacturers began to include built-in converters in their products, making it easier for consumers to access digital channels and programming. Today, most modern TVs come with built-in converters, including digital tuners, cable tuners, and satellite tuners, allowing consumers to access a wide range of channels and programming without the need for external devices.
What types of built-in converters are available in modern TVs?
Modern TVs often come with a variety of built-in converters, including digital tuners, cable tuners, and satellite tuners. Digital tuners allow TVs to receive over-the-air (OTA) signals, while cable tuners enable TVs to receive cable TV signals. Satellite tuners, on the other hand, allow TVs to receive signals from satellite TV providers.
In addition to these types of converters, some modern TVs may also include other types of converters, such as ATSC tuners, which allow TVs to receive digital broadcast signals, or QAM tuners, which enable TVs to receive unencrypted digital cable signals. The type of built-in converter included in a TV depends on the TV’s intended use and the types of signals it is designed to receive.
Do all modern TVs have built-in converters?
