VIDEO, AUDIO, AND HISTORICAL TREND DATA INTERPOLATION

摘要

A method in a computer system expands an initial set of trend data values by generating an interpolating the initial set of trend data values. An input data stream of the initial set of trend data values is received. Each initial trend data value is divided into two extrapolated values. A first extrapolated value is less than its corresponding initial trend data value. A second extrapolated value is greater than its corresponding initial trend data value. A time period of each initial trend data value is divided in half. The first extrapolated value is associated with a first half of the time period. The second extrapolated value is associated with a second half of the time period. An output data stream is a series of the first and second extrapolated values each over half of the time period to create an expanded set of trend values.
