Teräväpiirtokuva

Teräväpiirtokuva, often abbreviated as HD (High Definition), refers to a video resolution that is significantly sharper and more detailed than standard definition (SD) video. The term typically denotes a resolution of 1280x720 pixels (720p) or 1920x1080 pixels (1080p). Higher resolutions such as 4K (3840x2160) and 8K (7680x4320) are also considered forms of ultra-high definition, building upon the foundation of HD.

The introduction of teräväpiirtokuva represented a major advancement in visual display technology. It allows for finer details, smoother lines, and a more immersive viewing experience. This increased clarity is particularly noticeable on larger screens, where the limitations of standard definition become more apparent.

Teräväpiirtokuva is now the standard for most broadcast television, streaming services, Blu-ray discs, and video games. The widespread adoption of HD displays and content has transformed how people consume visual media, offering a significantly improved level of realism and detail compared to previous generations of video technology. The transition to HD required upgrades in cameras, recording equipment, broadcasting infrastructure, and display devices to fully realize its benefits.
