TLDR
In this paper, a data compression method for communications between a host computing system and a number of remote terminals is enhanced by adding new character and string extensions to improve the compression ratio and deletion of a least recently used routine.Abstract:
Communications between a Host Computing System and a number of remote terminals is enhanced by a data compression method which modifies the data compression method of Lempel and Ziv by addition of new character and new string extensions to improve the compression ratio, and deletion of a least recently used routine to limit the encoding tables to a fixed size to significantly improve data transmission efficiency.read more

System for customized electronic identification of desirable objects
TL;DR: In this paper, the authors proposed a system that automatically constructs a target profile for each target object in the electronic media based on the frequency with which each word appears in an article relative to its overall frequency of use in all articles, as well as a 'target profile interest summary' for each user, which target profile interest summaries describes the user's interest level in various types of target objects.
Patent
Secure data interchange
TL;DR: A secure data interchange system enables information about bilateral and multilateral interactions between multiple persistent parties to be exchanged and leveraged within an environment that uses a combination of techniques to control access to information, release of information, and matching of information back to parties as mentioned in this paper.
Patent
System and method for scheduling broadcast of and access to video programs and other data using customer profiles
TL;DR: In this paper, a system and method for scheduling the receipt of desired movies and other forms of data from a network which simultaneously distributes many sources of such data to many customers, as in a cable television system, is presented.
Patent
Location enhanced information delivery system
TL;DR: The Location Enhanced Information Deliver System Architecture (LEIA) as mentioned in this paper customizes the information that is displayed to an information recipient based on optimizing a match between information purveyors such as advertisers, and the information recipients who are local to the information delivery system.
Patent
Data compression apparatus and method
TL;DR: An apparatus and method for converting an input data character stream into a variable length encoded data stream in a data compression system is described in this article. But this method requires the input data characters to be stored in the history array.

Compression of individual sequences via variable-rate coding
Jacob Ziv,A. Lempel +1 more
TL;DR: The proposed concept of compressibility is shown to play a role analogous to that of entropy in classical information theory where one deals with probabilistic ensembles of sequences rather than with individual sequences.
Patent
High speed data compression and decompression apparatus and method
TL;DR: In this paper, a data compressor compresses an input stream of data character signals by storing in a string table strings encountered in the input stream, where each string comprises a prefix string and an extension character where the extension character is the last character in the string and the prefix string comprises all but the extension characters.
Patent
Apparatus and method for compressing data signals and restoring the compressed data signals
TL;DR: In this article, a search tree is constructed from the input data such that as each new segment is parsed, one new internal node of the tree is created from a leaf and new leaves are defined, one for each symbol encountered by the encoder plus an additional branch to represent all potential but unseen symbols.
Patent
Data compression,encryption,and in-line transmission system
TL;DR: In this article, an in-line data compression system which reduces the number of binary bits required to transmit a given text or similar message over a data network such as Telex or TWX was proposed.

A note on the Ziv - Lempel model for compressing individual sequences (Corresp.)
TL;DR: The symbolwise equivalent of the Ziv-Lempel algorithm is extended to incomplete parse trees and requires the proper handling of the comma when one phrase is the prefix of another phrase.
