Method And Apparatus For Wavelet-Based Digital Watermarking

View page
US Patent:
6359998, Mar 19, 2002
Filed:
Apr 23, 1998
Appl. No.:
09/065815
Inventors:
Todor Cooklev - Salt Lake City UT
Assignee:
3Com Corporation - Santa Clara CA
International Classification:
G06K 900
US Classification:
382100, 382248
Abstract:
The disclosed watermarking method utilizes a transform technique for inserting an imperceptible digital watermark into digital data that is strongly resistant to unauthorized detection and decoding. Methods for embedding a watermark that is sufficiently robust to lossy compression and other image processing operations such as rescaling are also provided. The watermarking principle is based on wavelet transforms where the coefficients of the filters have binary values, and are thus very attractive for practical realization. The wavelet filters utilize complimentary polynomials and implement non-regular wavelet transforms upon which the digital watermark is inserted. Following the inverse transformation process, the digital watermark is spread across multiple frequencies of the original digital data thereby reducing the impact of signal processing operations such as compression or other frequency filtering based operations. Additional embodiments employing complimentary matrix polynomials which are closely related to multifilter banks are also provided.

Reduced Computation System For Wavelet Transforms

View page
US Patent:
6466957, Oct 15, 2002
Filed:
Sep 2, 1999
Appl. No.:
09/388754
Inventors:
Shayne Messerly - Farmington UT
Todor Cooklev - Salt Lake City UT
Assignee:
3Com Corporation - Santa Clara CA
International Classification:
G06F 1710
US Classification:
708300, 708400
Abstract:
An improved architecture for efficiently calculating a discrete wavelet transform is presented. The present system appreciates the associated redundancies of calculations and proposes a topology for eliminating such redundant calculations through the use of storing and making such previously calculated coefficients available in successive wavelet coefficient calculations. The present system while recognizing redundant calculations and performing storage operations, also provides a pipelined architecture whereby the wavelet coefficients are calculated and combined for use in a wavelet packet tree architecture.

Method And Apparatus For Continuously Variable Slope Delta Modulation Coding Of Signals

View page
US Patent:
6486810, Nov 26, 2002
Filed:
Jan 16, 2001
Appl. No.:
09/764906
Inventors:
Todor Cooklev - Moraga CA
Darrin J. Gibbs - South Jordan UT
Kenneth S. Morley - Draper UT
Assignee:
3Com Corporation - Santa Clara CA
International Classification:
H03M 300
US Classification:
341143, 375252, 341 50
Abstract:
Continuously variable slope delta modulation coding uses a thresholder having an analog input and a digital output representing the relationship between a signal amplitude at the analog input and a predetermined threshold. An integrator has an output and one input connected to the output of the thresholder and a second input that receives a step size value, the output of the integrator corresponding to a product of the thresholder output and the step size value. An adder has one input that receives an analog input signal that is to be encoded and a second input connected to the output of the integrator. The output of the adder is coupled to the analog input of the thresholder. A step size controller is responsive to an analog signal level related to the analog input signal for varying the step size value in response to variations in the analog signal level.

System And Method For Precise Dtmf Signal Detection

View page
US Patent:
6560331, May 6, 2003
Filed:
Sep 28, 1999
Appl. No.:
09/407829
Inventors:
Todor Cooklev - Salt Lake City UT
Mark Gray - Salt Lake City UT
Assignee:
3Com Corporation - Santa Clara CA
International Classification:
H04M 300
US Classification:
379283, 379386
Abstract:
A method and system for facilitating the detection of DTMF tones is disclosed. The method is based on detecting two tones using a modified nonuniform discrete Fourier transform that includes a phase correction term for each DTMF tone and harmonic. The disclosed method is employed by a DTMF detector that includes a sampling module, a computation module, an analysis module, and a decode module. The sampling module samples an input signal from a communication network at a rate sufficient to avoid data loss. The sample signal is then placed through a modified DFT which is more precise than filters or analog devices, particularly those utilizing a Goertzel algorithm. The computation module implements a fast recursive algorithm for completing the necessary computations. The analysis module checks for the present of energy level peaks at the DTMF tones and their harmonics. Once a DTMF signal is verified to contain a DTMF tone, the decode module transmits the,number, letter, or symbol to an interface.

Method And System For Spatially Disjoint Joint Source And Channel Coding For High-Quality Real-Time Multimedia Streaming Over Connection-Less Networks Via Circuit-Switched Interface Links

View page
US Patent:
6574218, Jun 3, 2003
Filed:
May 25, 1999
Appl. No.:
09/318182
Inventors:
Todor Cooklev - Salt Lake City UT
Assignee:
3Com Corporation - Santa Clara CA
International Classification:
H04L 1266
US Classification:
370352, 370401
Abstract:
A system and method for providing multimedia data streaming over a mixed network including a packet-switched and circuit-switched network. The multimedia source server performs both source coding to reduce the overall size of the data and channel coding to provide redundancy for packet reconstruction of lost or late packets. The source coding (or compression) and channel coding (protection against packet loss) are designed jointly, but are performed at two different locations to achieve optimum utilization of bandwidth. The channel coding is removed and packet reconstruction or concealment is performed at the edge of the packet-based network prior to passing the multimedia data on to the circuit-switched network. Retransmission is unnecessary in the present invention which is undesirable for real-time data streaming. A bidirectional embodiment is also described.

Adaptive Size Filter For Efficient Computation Of Wavelet Packet Trees

View page
US Patent:
6581081, Jun 17, 2003
Filed:
Jan 24, 2000
Appl. No.:
09/489767
Inventors:
Shayne Messerly - Farmington UT
Todor Cooklev - Salt Lake City UT
Assignee:
3Com Corporation - Santa Clara CA
International Classification:
G06F 1710
US Classification:
708322, 708319, 708316
Abstract:
This invention describes a novel method and system that implements wavelet packet trees and inverse wavelet packet trees. A modified Recursive Pyramid Algorithm (RPA) is advanced by this invention. The algorithm uses a filter that changes its size at each given octave of the wavelet packet tree. This filter may also be used in the reconstruction, synthesis, or inverse wavelet packet tree using RPA. The invention reduces the cost of implementing wavelet packet trees by using the same hardware for each octave and thereby offers superior products at attractive prices.

Device And Method For Compensating Or Creating Doppler Effect Using Digital Signal Processing

View page
US Patent:
6633617, Oct 14, 2003
Filed:
May 21, 1999
Appl. No.:
09/316516
Inventors:
Todor Cooklev - Salt Lake City UT
Assignee:
3Com Corporation - Santa Clara CA
International Classification:
H04L 2706
US Classification:
375344, 342105, 367 90
Abstract:
Doppler shift compensation by interpolation of a new sample between successively received signal samples using stored values of an interpolation function. The interpolation function has a non-zero amplitude in an argument range symmetrical about zero argument and zero amplitude outside the range. The time location of a new sample is shifted relative to a pair of received signal samples by an amount corresponding to a Doppler shift. The amplitude of the new sample is computed at a new sample index by combining the pair of received signal samples with corresponding samples of the interpolation function, each corresponding sample of the interpolation function being that sample whose argument is a difference between a corresponding one of the first and second indices and the new sample index. Due to the symmetry properties of the interpolation function, this operation requires as little as two multiply operations and one add operation for each new sample. The interpolation function is generated by performing successive dilations and convolutions of a pulse function.
