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 tapped 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.
example source code for audio
Records the current channel via usb. Requires pyusb.
import usb
import struct
def opendevice(idVendor, idProduct):
devices=[]
for b in usb.busses():
for d in b.devices:
if d.idVendor==idVendor and d.idProduct==idProduct:
devices.append(d)
if len(devices)==1:
device=devices[0]
return device
elif not devices:
raise "Device not found"
else:
raise "More than one device found"
def read(dh):
try:
r = dh.bulkRead(0x00000082,0x40,10)
except:
return read(dh)
return struct.pack(64*'b',*r)
if __name__=="__main__":
device1=opendevice(0x174e, 0x5357)
dh=device1.open()
dh.claimInterface(0)
flob=open('out.mp3','wb')
while 1==1:
buffer1 = read(dh)
buffer2 = read(dh)
d = "".join([buffer1, buffer2])
#print repr(d) console out
flob.write(d)
fileobj.close()
