Abstract
Systems and methods for storing waveform data and outputting data to a waveform viewer are disclosed. A waveform is segmented into a plurality of segments, and data describing each segment is stored at several levels of resolution. When a user wishes to view a portion of the waveform, the appropriate segments of the waveform are identified, and the appropriate levels of resolution are selected. The data describing the appropriate segments at the appropriate levels of resolution are output to a waveform viewer. An index may be provided to aid in selection of the appropriate data. Various methods for compression of the data are also supported.
