 For instance, 1920×1080 pixel resolution interlaced HDTV with a 60 Hz field rate (known as 1080i60 or 1080i/30) has a similar bandwidth to 1280×720 pixel progressive scan HDTV with a 60 Hz frame rate (720p60 or 720p/60), but achieves approximately twice the spatial resolution for low-motion scenes.However, bandwidth benefits only apply to an analog or "uncompressed" digital video signal.With digital video compression, as used in all current digital TV standards, interlacing introduces additional inefficiencies.
