Document Type and Number:
Japanese Patent JP6869330
Kind Code:
B2
Abstract:
A program update device (100) communicates with a server and thereby updates a first program (410) stored in a program storage region (130p) of a storage unit (130), producing a second program. A reception unit (111) sequentially receives, from the server, compressed codes obtained by compressing codes constituting the second program. A first writing unit (112) writes the compressed codes received by the reception unit (111) to the program storage region (130p). A second writing unit (113) decompresses the compressed codes sequentially read from the program storage region (130p), and writes the decompressed codes to the program storage region (130p), thereby writing the second program to the program storage region (130p).
