Installing DVBlast
==================
No autotools yet... You have to tweak the Makefile by hand, especially
if your kernel is S2API-enabled but not your distribution (indicate the
path of your kernel where appropriate). Compile the program with `make`
and install with `make install`. It requires the installation of libdvbpsi
0.1.6 or later and libdvbpsi-devel (depending on your distribution).
Compile the program with `make` and install with `make install`. Your
kernel must support DVB S2API which was merged in Linux 2.6.28 and released
on 24 Dec 2008.
DVBlast 2.X no longer requires libdvbpsi runtime and libdvbpsi-devel for
compilation. Instead you must install biTStream on your build machine (no
runtime library is needed).
To install biTStream, clone git repository and run `make install`.
git clone git://git.videolan.org/bitstream.git
cd bitstream
make install

Buffering
=========
DVB cards usually output packets in big chunks. This can be problematic
with low bitrate multiplexes. By default, DVBlast bufferizes 200 ms
and tries to smooth the output. It may be desired to change this value
with the -L option. The appropriate value for the output latency should be :
chunk_size / multiplex_bitrate
The chunk size for saa7146-based cards is 512000 bits ; for
cx23885-based cards is 192512 bits. The chunk size can be modified with
an appropriate kernel patch (see extra/). The multiplex_bitrate depends
on the symbol rate and many other factors such as the modulation.
The current default value allows for multiplex_rates as low as 2.56 Mbi/s.
Smaller multiplexes are rare but exist, so in that case you may want to
increase the buffer size. A typical DVB multiplex is 30 or 40 Mbi/s, so
the default introduces a superfluous latency ; the buffer can be lowered
to 50 ms if latency is an issue.
DVBlast also has another parameter called "max retention time" (-E).
This controls how TS packets are grouped together in IP datagrams : the
difference between the theorical output times of the first and the last
TS packets cannot exceed the maximal retention time.
IP datagrams are normally output at the output time of the earliest TS
packet ; it implies that the next TS packets are sent too soon and must
be buffered at the receiver level. ISO/IEC 13818-1 makes no provision for
this, since IP wasn't in mind when designing TS, so in theory we risk a
buffer overflow.
However normal IP receivers feature a jitter buffer which can absorb the
overflow ; DVB recommends a 50 ms buffer. DVBlast's default maximal
retention time is just below, at 40 ms, which should be fine in most
situations.
If some anal set-top-box complains about buffer overflows or clock issues,
you may try to lower the value ; the drawback is that on low bitrate
streams it will introduce padding. People with low bitrate streams and
nice receivers with big buffers can raise this value to avoid superfluous
padding and lower the total bitrate.
Please bear in mind though that setting a value for max retention time
greater than the output latency has no effect.

.SH DESCRIPTION
DVBlast is a simple and powerful streaming application based on the linux-dvb API.
It opens a DVB device, tunes it, places PID filters, configures a CAM module, and demultiplexes the packets to several RTP outputs.
DVBlast is a simple and powerful streaming application based on the linux-dvb
API. It opens a DVB device, tunes it, places PID filters, configures a CAM
module, and demultiplexes the packets to several RTP outputs.
DVBlast is designed to be the core of a custom IRD or CID, based on a PC with Linux-supported DVB cards.

DVBlast does not do any kind of processing on the elementary streams, such as transcoding, PID remapping or remultiplexing. it does not stream from plain files, only DVB devices. If you were looking for these features, switch to VLC.

About DVBiscovery
=================
DVBiscovery is a shell script that tries to tune a number of frequencies
(from a config file), and stops after it has found a match. It then dumps
the output of DVBlast to the standard output, so that an external process
can parse it and find relevant information there. Typically, you would
want to get the network ID from the NIT, which unically identifies the
network you are on.
DVBiscovery is therefore a sort of scanning program, but doesn't aim at
exhaustivity (there are already programs doing that). It tries to guess
where you are without any external information.

About DVBlast kernel patches
============================
These kernel patches are designed to dramatically improve the latency
between the DVB card and DVBlast's output, especially on low symbol rate
transponders, at the expense of a slightly higher CPU consumption.
Basically they decrease the size of the transmission buffers from the card
to 4 kB, so that TS packets are handled more frequently.
