high definition video (HDV)
High Definition Video (HDV) is a video format developed by Sony and JVC for recording high definition television( HDTV).
HDV, as the successor format to DV, can record HDTV signals with resolutions of 960 x 720pixels (HDV1) and 1,440 x 1,080 pixels (HDV2), both interlaced and progressive scan with the different frame rates. The aspect ratio is always 16:9. HDV uses MPEG-2 for video compression and has a data rate of 25 Mbit/s at 1,080i; audio compression uses Dolby Digital 5.1 and AC-3(AudioCodec 3). The color subsampling used in HDV works with 4:2:0, the bit depth is 8 bits. Theoretically, maximum data rates of 12 GB/h can be achieved. Standardized HDV is used in amateur and semi-professional applications.
