Abstract
A digital recording device for storing video data is disclosed. The digital recorder intelligently records less data than is provided to it by determining which data to record, and which data to eliminate. In some embodiments, the recorder drops or modifies overscan data from a video frame prior to compressing the data, thereby relieving a data encoder from unnecessary data operations, and saving storage space.
