1080i is interlaced; 720p, 1080p, and 2160p are progressive, i.e. non-interlaced. My understanding is that most commercial Blu-rays are progressive encodings, broadcast may be different. (1080i was common back in the day.) Interlaced had the advantage of looking better for fast motion, such as in sports; for example, 480i with 60 fields/sec would look better than 480p with 30 fields/sec, at equivalent bandwidth. |
