Abstract
This system adaptively assigns picture types used for temporal compression to frames of streaming video at the input. Based on threshold testing of two metrics that are measures of distance between the frames at the input, a frame may be assigned to be compressed as an I, P, or B frame or be skipped over by the system without being coded at all.
