Description & Goals

Summary

BookBeaming receives static content using a conventional World Space satellite radio.

Status

The prototyp works with the TONGSHI DAMB-R Radio and the Africa Learning Channel. As of 26.01.08 any active audio stream can be taped and recorded. This was however not the original purpose. Since January the prototyp is broken due to changes in the codewords used. Specifications appear to be nonpublic.

Goals

Access to a wide range of content from the weather report to health care.available content

Collaboration

Sharing one satellite radio could bypass satellite radio shortage in an particular areas.
