Sony Software Builds on Copyright Control
- Share via
Sony Corp., the world’s second-largest consumer electronics maker, has developed software incorporating new technology to enhance the copyright protection of music and movies available through the Internet.
The software, using a technology called OpenMG X, gives distributors more control over how their digital content is used, Sony said. For instance, it will allow content providers to limit the number of times a song can be copied and played.
Movies, music and games are readily available for swapping over the Internet, sparking concern among record companies and movie studios. Sony has blamed digital piracy for eroding profit at its music business.
The creator of the Walkman personal stereo plans to release several models of its Vaio PCs this year that will act as home servers capable of storing and playing movies and music in digital form.
Sony shares rose $1.35 to $43.85 on the NYSE.
