Backbone Networks has announced Backbone Radio Pro 4.1, its internet radio-station software.

It's an integrated radio-station software suite, that includes all the automation, streaming and content-creation software to implement a complete MPEG-4 internet station using Macs in combination with Linux or Mac OS X servers.

The Universal application works with both Intel and PowerPC-powered Macs. This version offers several new features designed to boost online radio station revenues, including clickable images and text so that listeners can buy products while listening to a channel. The software also offers demographic listener information to help stations secure ads sales.

Richard Cerny, president of Backbone Networks, said: "We are particularly proud that our use of global media standards like QuickTime and MPEG-4 for open standards-based streaming gives users and broadcasters the widest range of listening choices, including iPods, Macs, PCs and 3G-enabled mobile phones."

This version of Backbone Radio Pro was developed in Cocoa. Broadcasters can simultaneously webcast their streaming shows while commanding the software to create, annotate and post podcasts of the show. The software also creates podcast chapters and inserts images specific to each chapter.

A 30-day demo version of the software is available. It costs $4,500.
