How does HDV compression compare with other formats? Isn it more heavily compressed?
Actually, no! In fact, the GY-HD110U employs less compression than some popular competing formats. There is a very large amount of data in an uncompressed high definition digital video signal. All modern video recording formats use various data reduction methods to fit the signal onto the digital storage media (DSM.) These data reduction techniques could be referred to as “compression” in a general sense, because the ultimate goal is to recover a picture that closely resembles the image that first entered the camera lens. One method used by some manufacturers is to reduce the number of picture elements (pixels) on the camera’s imaging device. Frequently, partial resolution chips are used, typically 960 x 1080, thus reducing the amount information to be sampled. Less picture information is less demanding on the compression engine, but can result in reduced image sharpness. The GY-HD110U does not make this compromise, since its CCDs provide a full 1280 x 720 progressive image. Another tr
