Installation

Get the latest file from the jdvb pakage. Extract it and enter the the jdvb-X.X/JDVBDist folder.

Server and Client Configuration

To startup, edit tvb.conf. The format of the config file is such:

variable=<value>
# and comments start with "#"

For both the client and server, these two variables need to be set (a):

server=<your.own.server>
port=<greater than 1024>

In addition to the above (a), the server needs these two variables:

tzap=<location of tzap>
dvbstream=<location of dvbstream>

In addition to (a), the client needs this one variable:

dvbplayer=<choice of player that reads rtp streams>

It is OK to share the tvb.conf file, as having extra variables does not hurt any of the applications.

A note on piping stdout⁄stderr for the player

If you are piping anything for the dvbplayer, it will not work, i.e: if you are using:

dvbplayer=dumprtp | mplayer -

It will not work, as Java's method of executing system specific calls actually grabs the output of the first command into a buffer and hence (in the example above) it does not "pipe" to mplayer. The work around this is to have a simple script that executes the above command: Lets call this file startplayer.sh:

#!/bin/bash
dumprtp | mplayer -

And set the dvbplayer variable to:

dvbplayer=<location of startplayer.sh>

Don't forget to chmod +x the startplayer.sh file! This (solution) will actually cause the Java execution call system to treat it as one command, and hence the "pipe-ing" will work.

The Server as a Daemon

The server application at the moment does not have a daemon interface and hence can not run as a "service" at the moment. You can install it manually, but would require simple startup scripts. The quickest solution is to put in the command described in usage section under /etc/rc.d/rc.local or wherever your boot up script is located. This will be fixed in future releases and the server will run as a non-privelaged user.

The usage section has instuctions on how to run the server and client applications.
