Now just like 720p vs 1080i, a signal can be transmitted in either format but still displayed differently on the HDTV. ... the video is sent out of the player at 1080p 24 frames per second, per ...
D-5 HD uses standard D-3/D-5 videocassettes to record HD material, using an intra-frame compression with a 4:1 ratio. It was introduced in 1994. [2] D-5 HD supports the 1080 and the 1035 interlaced line standards at both 60 Hz and 59.94 Hz field rates, all 720 progressive line standards and the 1080 progressive line standard at 24, 25 and 30 frame rates.
Non-cinematic HDTV video recordings intended for broadcast are typically recorded either in 720p or 1080i format as determined by the broadcaster. 720p is commonly used for Internet distribution of high-definition video, because most computer monitors operate in progressive-scan mode. 720p also imposes less strenuous storage and decoding ...
1080i is a term used in high-definition television (HDTV) and video display technology. It means a video mode with 1080 lines of vertical resolution. The "i" stands for interlaced scanning method. This format was once a standard in HDTV. It was particularly used for broadcast television.

The 60 Hz version is able to shoot and record native 24-frame/s progressive video. [20]
without mentioning the relative refresh rates of the two standards he's comparing. I think Algr assumed that he was comparing 720p/50 with 1080i/25 (say) because the bandwidth used by both is similar. I think 83.104.249.240 assumed that he was comparing 720p at any frame rate with 1080i at any frame rate. From those standpoints both make valid ...
