What features does a set-top box (STB) with digital only capabilities have?

A set-top box (STB) with digital-only capabilities is designed to receive and decode digital television signals, which means its primary feature is the presence of a digital tuner. This enables it to access high-definition content and digital channels effectively.

In correct assessments, the inclusion of high-definition TV and digital outputs in the feature set is important. High-definition capability allows the STB to relay superior image quality, while digital outputs ensure the STB can connect with modern televisions and audio systems, maximizing the viewing experience.

Contrasting options that suggest analog tuners would indicate that these boxes are designed for older technology, which does not align with the definition of digital-only capabilities. In this context, the full embrace of digital technology, including high definition and various digital outputs, is what makes the correct choice comprehensive, reflecting the current standards and expectations for modern STBs.
