Adoption of 720p/1080i formats to comply with progressive and interlace specifications for high- definition recording and playback
The HDV format complies with both the 720 scanning lines (progressive)/1280 horizontal pixels 720p format (60p, 30p, 50p, 25p), and the 1080 scanning lines (interlace)/1440 horizontal pixels 1080i format (60i, 50i). This ensures the recording and playback of high-resolution video for the high-definition era.
