Watching streams using android tablet

We have now covered the basics in streaming DVB video content over the internet. If you are on the go and have some internet access you can easilly watch this streams using your chinese android tablet. All you will need is an Android running tablet, internet connection (wifi will do the best) and some streaming software. In my experience MX Player which can be found on Android Market does it the best.
Just open MX player and after it loads choose Menu key. It will then offer you to play network stream. Now all you have to do is enter the network path to your stream and start enjoying it.

DVB-T streaming

In this post I will try to explain what is the easiest way to stream digital terrestrial channels (DVB-T) over internet. All you will need for this is a cheap DVB-T tuner (easily obtained on Ebay, Amazon,...)
Install the supplied drivers and check if the device is working fine on your system.
The next thing is to install VLC player. You can download it at www.videolan.org

Then you will have to tune to the channel you want to stream.

You can find detailed information on what frequency it is broadcasted from your DVB-T provider.

When you can watch it locally you can start streaming.

Streaming using DVB Dream

DVB Dream is one of the finest ways to watch digital satellite, terrestrial or cable tv on your computer. It can also used as a streaming server. This is very convenient when you want to watch TV over nertwork. It is very easy to use it in local network (LAN). When you try to use it over internet there are some problems including bandwidth limitation.

What do you need:
Some kind of DVB tuner (DVB-T, DVB-S or DVB-C) with BDA driver support.
DVB Dream (www.dvbdream.org)
VLC player (www.videolan.org)

Install the DVB tuner and run DVB Dream. Please see DVB Dream online documentation if you have any problems installing it or searching for new channels.
After you successfully installed and started DVB Dream it is time to install VLC player. VLC player is a cross platform multimedia player which can chew almost any video file you could imagine.
Beside this it can be used to transcode the fideo file or stream that it is playing. This is very useful if you want to stream high quality video stream over internet. Since upload speeds are usually limited you will need to recompress the video stream. Average video stream (satellite or DVB-T) usually takes some 5 Mbits per second. If you have such internet upload connection you can looselesly stream it. If your connection is eg. 1Mbit then you will need to recompress the video. This can be done by reducing the resolution and bitrate.


After you install all the necesary software it is time to make the correct settings.

Run DVB Dream and tune to desired channel.

Go to Options / Preferences / LAN
Check the ticker Active, you can leave all other things as they are.

Now go to Options / Preferences / Integration
Path field indicates the location of VLC installation. Usualy it can be left as it is. Otherwise change it.

The most important setting is in command line:
udp://@ :sout=#transcode{vcodec=h264,vb=650,scale=0.75,acodec=mp3,ab=64,channels=1,samplerate=44100}:http{mux=ts,dst=:8085/}

I won't go into details here. This are the settings which are functioning very well with 1Mbit upload speed.
vcodec indicated that we will be using h264 for streaming, scale scales the resoulution by 0.75 and vb tell us the bitrate we will be using for streaming.
The most important setting is at the end of line. dst=:PORT_NUMBER
This indicates which port will be used for streaming. You will have to open this port on your Router / Firewall / NAT and direct it to the computer running the VLC.

After you have done all this, you have to run the streaming by selecting Tools / VLC. After you do it, VLC will start and it will automatically start streaming the channel you are watching.

In remote location you can start the stream by starting VLC, and opening a network stream http://your_home_ip_address:PORT_NUMBER.
