 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.

+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.
