Which one of the following digital broadcast standards is adopted in Europe, Asia, and Africa?

The digital broadcast standard adopted in Europe, Asia, and Africa is DVB, which stands for Digital Video Broadcasting. This standard is widely accepted and implemented across many countries in those regions for digital television broadcasting. DVB includes various specifications that cater to different transmission methods, including terrestrial, satellite, and cable, making it versatile for a range of broadcasting environments.

DVB has become the foundation for many countries transitioning from analog to digital broadcasting, providing improved picture and sound quality, as well as a more efficient use of the broadcast spectrum. Its global acceptance and adaptability are key factors that have led to its widespread implementation, especially in Europe, where it has effectively replaced older analog standards.

In contrast, ATSC is primarily used in the United States and Canada, ISDB is specific to Japan and a few other Latin American countries, and NTSC refers to a previous analog television standard mainly used in North America. Thus, DVB stands out as the correct choice for regions like Europe, Asia, and Africa.
