TTsüsteemide, also known as Teletext systems, are digital information services that are transmitted alongside television broadcasts. They provide a range of information, including news, weather, sports scores, and other relevant data, directly to the viewer's television screen. Teletext systems were first introduced in the 1970s and have since evolved to include interactive features and multimedia content.

The basic operation of a Teletext system involves the transmission of data pages, which are encoded and sent alongside the television signal. These pages can be accessed by viewers using their television's remote control, allowing them to navigate through different pages of information. Teletext systems are typically non-interactive, meaning that viewers can only receive information and cannot send data back to the broadcaster.

One of the key advantages of Teletext systems is their ability to provide up-to-date information in real-time. This makes them particularly useful for delivering news and weather updates, as well as sports scores and other time-sensitive data. Additionally, Teletext systems can be used to provide additional information about television programs, such as episode guides and cast details.

Teletext systems have also been adapted for use on other platforms, such as mobile devices and computers. This has allowed for the expansion of Teletext services to include interactive features, such as the ability to send messages or participate in online polls. However, the core principle of Teletext systems remains the same: the transmission of digital information alongside a broadcast signal.

In recent years, Teletext systems have seen a decline in popularity due to the rise of the internet and other digital media platforms. However, they continue to be used in certain regions and by specific audiences, particularly in areas with limited internet access. Despite their declining popularity, Teletext systems remain an important part of television broadcasting history and continue to provide valuable information services to viewers around the world.
