What is the format of HDV in Sony A 1C camera? What is the DV format? What's the difference between them?

The HDV format of Sony A 1c is 1440* 1080, with 25 or 30 interlaced frames and a bit rate of about 30M.

DV is interlaced scanning, with 720*576 frames, 25 or 30 frames per second, and the code rate is about 20M.

The difference between the two is that the border size is different. The screen size of HDV is much larger than that of DV, which is the difference between HD and SD in general. Secondly, the difference of pixel ratio, that is, the aspect ratio of each small pixel, HDV is a square pixel with a ratio of 1: 1, DV is a rectangular pixel with a ratio of 4: 3; There is also a bit rate ratio, which is the digital space occupied by video every second. HDV is 30M/ s, DV 15-25M/ s, and the format of HDV is large, which of course takes up more space.
