What system advanced television to high definition (HD)?

The system that advanced television to high definition (HD) is Multiple sub-Nyquist sampling encoding, commonly known as MUSE. MUSE was developed in the late 1980s and early 1990s in Japan as a method to transmit high-definition television signals over existing broadcasting infrastructure. It uses a technique that allows for the efficient encoding of high-resolution video by taking advantage of the human visual system's perception capabilities.

MUSE supports a higher level of detail and image quality compared to standard definition television. It played a significant role in paving the way for the development of HD standards that are widely used today. This technology laid the groundwork for subsequent advancements in high-definition television, ultimately leading to the establishment of more standardized digital broadcasting formats.

The other options, while related to video technology, either do not specifically pertain to the transition to high definition television or represent more recent advancements in video compression and transmission technologies.
