Abstract
The present invention provides a method, system, and computer program product for encoding (and subsequently decoding) a sequence of periodic byte values that have a vertical correlation (e.g. so that they can be more efficiently stored and/or electronically transmitted for use in a real-time system or resource-constrained system). Redundant values are omitted through use of marker bytes and bits masks which indicate when a set of values is unchanged and which of the set have changed, respectively. In this manner, the resources required for transmitting, processing, and/or storing the values is reduced. In some systems, the reduction may enable shortening the periodic interval length, such that values of a finer granularity can be processed. An example scenario in which the present invention may be used advantageously is for transmitting periodic input data to a robot controller, in order to control movement of the robot.
