Features

Small decompression library

The decompression library for MIDP / DoJa is only 1.5 KB ( after JAR compression ). It can be embedded easily on mobile Java applications which have strict size limitations.

Multi platform

SophiaSCALE is already compatible with Java platforms (PC / DoCoMo DoJa / au, Vodafone MIDP ), but is also soon to be adapted for BREW platforms.

Basic Specification

• Both of the Compression/Decompression Libraries are programmed in Java.
• The compression algorithms specifically tuned for ring tone melodies achieve an average compression ratio of 66% and a peak ratio of 85%.
• The size of the client module for decompression on a DoJa/MIDP phone is 1.5 kb (after JAR compression).

Restrictions

• A 2G byte limit is imposed the size of files to be compressed by SophiaSCALE.
• CRC or Checksum will not be generated. When SophiaSCALE is used in communication networks where errors occur frequently, it is up to the developer to implement another error check module. In case of HTTP, it needs not be implemented because TCP/IP will assume responsability
