She also said Sony was intensively promoting ATRAC and OpenMG
among content service providers.
Earlier this year, IBM and Sony announced that they had reached a similar plan to realize the interoperabilitiy between OpenMG and IBM's Electronic Music Management System (EMMS), a comprehensive e-business solution for the secure sale and downloading of music over the Internet.
Today's announcement demonstrates the broad support Sony is gaining for OpenMG and portable devices from innovative companies active in electronic music distribution solutions.
Sony's OpenMG is designed to support multiple download platform and audio devices of electronic music distribution, which gives music companies various options for secure, SDMI-compliant solutions, as a result of Sony's above-mentioned agreements.
In addition, Microsoft and Sony will enable playback of Windows Media Audio content on the Memory Stick Walkman using OpenMG and ATRAC3 technologies.
OpenMG is a copyright protection technology including DRM, which consists of three key functions: allowing music download through multiple electronic music distribution platforms, enabling to playback music files and CD ripping on PCs (OpenMG Jukebox), and transferring contents securely from PCs to portable devices.
It is the intent of IBM and Sony to make their respective EMMS, MagicGate and OpenMG
technologies comply with the guidelines of the Secure Digital Music Initiative (SDMI).
This will enable OpenMG compliant personal computers and MagicGate compliant audio player/recorders, such as a "Memory Stick Walkman," to receive content purchased and downloaded over the Internet using EMMS.
Sony's MagicGate and OpenMG technologies have been designed to prevent unauthorized copying, playback and transmission of protected digital music content.
