DV Video Format

The DV format is a common standard and high definition digital tape system that uses DCT intraframe compression to record a high quality video stream. The numbers used after the �DV� name represent the data rate used to record the images � DV25, for example, signifies a 25 megabit data stream. The higher the bit rate, the less compression (larger data file) is used to record the image. Most major video equipment manufactures support the DV25 format (also referred to as miniDV). Sony and Panasonic offer variants on the DV25 format known as DVCam and DVCPro. Panasonic also offers a proprietary DV50 standard definition format along with DV100, a high definition format.
