Time-varying randomization for data synchronization and implicit information transmission
First Claim
1. A memory for storing data for access by an application program being executed on a data processing system, comprising:
- a data structure stored in said memory, said data structure including information resident in a database used by said application program and comprising, a plurality of packet structures used for the transmission of data, wherein each packet structure comprises a dynamic range data object of spatially and temporally disjointed data objects within the data, and a set of block attributes for each dynamic range data object.

Abstract
The present invention provides a system and method for the time-varying randomization of a signal stream to provide for a robust error recovery. A current block of data is randomized in accordance with data from the current block and data from at least one temporally adjacent block of data. The present invention also provides a system and method for time-varying derandomization of a randomized signal stream and alternately delayed-decoding of the signal stream. Randomized data is derandomized using the current block of data and data from at least one temporally adjacent block. In addition, decoding of the current block and the adjacent block is delayed in order to facilitate recovery of lost or damaged compression parameters of encoded data.
