What is the standard format for high-definition video signals?

The standard format for high-definition video signals is 1080p, which stands for a resolution of 1920x1080 pixels. This format is widely recognized as full high definition (FHD) and has become a benchmark in the industry for delivering clear, high-quality images.

The "p" in 1080p indicates that the video format is progressive scan, meaning each frame is drawn line by line in sequence, which results in smoother motion and higher clarity for fast-moving content compared to interlaced formats.

While 720p is also considered high definition, it is generally regarded as standard HD rather than full HD. The 1440p format, or QHD, is less common in traditional broadcasting and is often used in computer monitors and gaming. 4K, with its 3840x2160 resolution, offers even higher definition but is not classified under standard HD formats; instead, it falls into the category of ultra-high definition (UHD).

Given the widespread adoption and recognition of 1080p as full HD in various broadcasting, streaming services, and display technologies, it stands as the current standard for HD video signals.
