streaming ascii tv

this package takes the output of 'aatv' http://n00n.free.fr/aatv/ and stream compressed ascii-tv signal to its clients.

aatv in turn uses v4l (in the linux kernel) and aalib http://aa-project.sourceforge.net/aalib/

software that does something related to multicasting/multiplexing of data streams.

but none of these could take the output of one program and stream it compressed to various independent clients.

so I started out with this project

how to use

how to configure

configuration is currently done by modifying the source.

files in package: (download here)

readme.txt
text version of this file.
Compress/Compress.pm
wrapper for /usr/bin/compress
this gives a better realtime streaming performance than gzip or zlib * maybe if I do per-frame compression, and use 'flush' it will work with zlib too.
TVData.pm
wrapper for aatv command
mcast.pl
main program
tvclient.pm
wrapper for client socket, handles compression
tvstream
v0.0 version, does not support multiple clients
aatv.patch
