videotekstissä

Videotekstissä, also known as teletext, is a digital information service that is transmitted along with a television broadcast. It was developed in the 1970s and 1980s as a way to provide additional information to viewers, such as news updates, weather forecasts, and program schedules. Videotekstissä is accessed by viewers using a teletext decoder, which is typically built into modern television sets.

The service operates by transmitting data alongside the television signal, which is then decoded by the viewer's teletext decoder. This data can include text, graphics, and even simple animations. The information is organized into pages, which can be navigated using a simple keypad or remote control.

Videotekstissä has been used for various purposes, including providing real-time information, such as stock market updates or sports scores, and offering interactive services, like online shopping or voting. However, the popularity of videotekstissä has declined in recent years due to the rise of the internet and other digital platforms that offer similar services.

In some countries, videotekstissä has been replaced by electronic program guides (EPGs) or other digital services. However, it remains in use in some regions, particularly in countries where internet access is limited or expensive. The legacy of videotekstissä can still be seen in the form of teletext pages that are broadcast alongside television programs, providing additional information to viewers.
