ISDB-T, or Integrated Services Digital Broadcasting-Terrestrial, is a digital television broadcasting standard developed in Japan. It allows for the transmission of high-quality audio and video signals over terrestrial networks, enabling viewers to receive digital TV broadcasts using antennas. This standard supports various features, including multiple audio tracks, subtitles, and interactive services. ISDB-T is widely used in several countries, particularly in Latin America, where it has been adopted for its efficient use of bandwidth and ability to deliver high-definition content.
