Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 370: Multiplex Communications

This is the generic class for multiplexing or duplexing systems, methods, or apparatus.

Subclass 206: Quadrature carriers
Subclass 395.42: Based on priority
Subclass 485: Subscriber carrier
Subclass 486: Program distribution
Subclass 487: Combined communication of diverse information types
Subclass 537: Multiplexing plural input channels to a common output channel

Class 375: Pulse Or Digital Communications

This is the generic class for pulse or digital communication systems using electrical or electromagnetic signals. Such communication includes transmitting an intelligence bearing signal from one point to another in the form of discrete variations in some parameter of the electrical or electromagnetic signal.

Subclass 240.01: Television or motion video signal
Subclass 240.25: Specific decompression process
Subclass 240.26: Associated signal processing
Subclass 261: Quadrature amplitude modulation
Subclass 296: Antinoise or distortion (includes predistortion)
Subclass 298: Quadrature amplitude modulation
Subclass 354: SYNCHRONIZERS

Class 332: Modulators

A modulator combined with structure for measuring or indicating some aspect of the modulation process or characteristic of the modulated signal is classified here. Specifically, measurement or indication of a frequency or amplitude modulator A specific modulating signal source (e.g., microphone or photocell). A combination including both a modulator and a demodulator is classified.

Subclass 103: PHASE SHIFT KEYING MODULATOR OR QUADRATURE AMPLITUDE MODULATOR

Class 380: Cryptography

Equipment and processes which (a) conceal or obscure intelligible information by transforming such information so as to make the information unintelligible to a casual or unauthorized recipient, or (b) extract intelligible information from such a concealed representation, including breaking of unknown codes and messages.

Subclass 212: Plural video stream multiplexing
Subclass 37: Block/data stream enciphering

Class 713: Electrical Computers And Digital Processing Systems: Support

Subclass 150: MULTIPLE COMPUTER COMMUNICATION USING CRYPTOGRAPHY

Class 714: Error Detection/Correction And Fault Detection/Recovery

This class provides for process or apparatus for detecting and correcting errors in electrical pulse or pulse coded data; it also provides for process or apparatus for detecting and recovering from faults in electrical computers and digital data processing systems, as well as logic level based systems.

Subclass 762: Burst error correction
Subclass 788: Burst error

Class 725: Interactive Video Distribution Systems

This class contains interactive video distribution processes, systems, and elements thereof, which are characterized by point-to-multipoint system configurations, and which are used for the unidirectional distribution or delivery of motion video data resulting from interactions between systems operators (access or service providers) or users (subscribers) and systems elements. These systems include dedicated communications systems, such as television distribution systems, which primarily distribute or deliver motion video data in the manner indicated, but which may, in addition, provide a framework for further, diverse data communications or services in either unidirectional or bidirectional form. Typically, system operators interface with transmitter-side elements or users interface with receiver-side elements in order to facilitate, through interaction with such elements, the dynamic control of data processing or data flow at various points in the systems. This interaction is typically occasional or intermittent in nature.

Subclass 138: Headend
Subclass 144: Headend

Class 709: Electrical Computers And Digital Processing Systems: Multicomputer Data Transferring

This class provides for an electrical computer or digital data processing system or corresponding data processing method including apparatus or steps for transferring data or instruction information between a plurality of computers wherein the computers employ the data or instructions before or after transferring and the employing affects said transfer of data or instruction information. The class includes - process or apparatus for transferring data among a plurality of spatially distributed (i.e., situated, at plural locations) computers or digital data processing systems via one or more communications media (e.g., computer networks).
