With advances in computer technology, digital video is becoming more and more common in various aspects of life, including communication, education, training, entertainment, and publishing. The result is massive amounts of video data that either already exist in digital form, or that are soon to be digitized. According to an international survey [42], there are more than six million hours of feature films and video archived worldwide, with a yearly increase rate of about 10%. This would be equal to 1.8 million GB of MPEG encoded digital video data if they were digitalized. Another example is the NASA’s Earth Observation System, which has the capability of generating about 1 terabyte of image data per day when fully operational [45].
