1080i60

1080i60 refers to a video format used in high-definition television. The "1080" signifies the vertical resolution of the image, meaning there are 1080 horizontal lines of pixels on the screen. The "i" stands for interlaced, a technique where each video frame is split into two fields. One field contains the odd-numbered lines and the other contains the even-numbered lines. These fields are displayed alternately, creating the illusion of a higher frame rate and smoother motion. The "60" indicates the field rate, meaning 60 fields are displayed per second. In practice, this results in approximately 30 full frames per second, as each frame is composed of two fields. This format was widely adopted for television broadcasting and early high-definition video production. It offers a significant improvement in picture quality over standard definition formats. However, interlaced video can sometimes exhibit artifacts, especially during fast motion, which led to the development and adoption of progressive scan formats like 1080p.
