Title:
DATA COMPRESSION TRANSMISSION SYSTEM, INTERMEDIATE SERVER, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/170601
Kind Code:
A1
Abstract:
Provided is a technology for compressing and transmitting data without damaging real time property. In this data compression and transmission system which allows a central server to collect data generated by a plurality of devices through a network, an intermediate server is disposed between the plurality of devices and the central server, each of the plurality of devices is provided with a packet cache processing unit which converts, on the basis of a cache, the generated data into a hash value, and the intermediate server is provided with: a packet cache processing unit which recovers, on the basis of the cache, the hash value into the original data; a buffering processing unit which integrates data and outputs the integrated data as a long packet; and a compression coding processing unit which compresses the data and generates encoded data.
