packet-server.py takes a teletext packet stream and serves it to multiple clients.
The script attempts to consume 42 byte packets from stdin every 20ms unless an input filename is specified with -i
test.py is a test client which connects to the server and outputs packets to stdout
The port is set using the -p argument, and the number of lines per field by -l
The server can be tested using example.t42:
python3 packet-server.py -p 19761 -l 16 -i example.t42
A suitable packet stream can be generated using https://github.com/peterkvt80/vbit2
For example: vbit2 --dir ~/teletext | python3 packet-server.py -p 19761 -l 16
