TOKYO (AP) _ Sony Corp.'s video-game unit and Japan's biggest telecommunications company are teaming up to offer broadband services in Japan such as downloads of music and game characters for the PlayStation 2 machine.

The service from NTT Broadband Initiative, a unit of telecom giant Nippon Telegraph and Telephone Corp., will begin in April, both sides said Tuesday.

NTT Broadband's alliance with Sony Computer Entertainment, the video-game unit of the Japanese electronics and entertainment giant, will make broadband downloads on the PlayStation 2 possible. Fees for the service have not yet been decided.

Attachments including a hard disk to connect to the network will be provided, said Sony Computer Entertainment spokeswoman Yoshiko Furusawa. Downloads will likely be characters or other enhancements to games in the beginning, rather than entire games, she said.

The downloads for PlayStation 2 will also be offered as a service to subscribers of So-net, Sony's Internet-linking provider service, starting in April, Sony said. Fees are not yet set, Sony Communication Network Corp. said.

The fees will be in addition to those for the broadband link to homes, which costs about $16 a month from NTT.
