What is set-top box
A set-top box (STB) or set-top unit (STU) is an information
appliance device that generally contains a tuner and
connects to a television set and an external source of
signal, turning the source signal into content in a form that
can then be displayed on the television screen or other
display device.
A consumer Palcom DSL-350
satellite-receiver;
the
Intermediate
frequency
demodulation tuner is on the
bottom left, and a Fujitsu MPEG
decoder CPU is in the center of
the board. The power supply is
on the right.

Main parts of STB
Tuner & demodulator
- transform radio waves to data stream
22Mbps DVB-T Mux
Decryption HW/SW
- Smartcard reader and conax decoder
Content Player
- HW accelerated MPEG4 video*
- MPEG2 / AC3 / HE-AAC / DTS audio
* On Raspberry Pi we need to buy license for MPEG2 video that costs 2.4 GBP.
HW audio codec not licensable, yet.

What is in the box - software
RaspBMC operating system:
- Based on Raspbian = Debian Whezzy ARMv6 port
- XBMC 12 binary
- Tvheadend 3.4 binary
Need to install
- PCSC tools and libs
- OSCam decoder, build from source
- LCDproc + patched lcd driver
- firmware for DVB-T tuner sticks

Setup
Exit to console or connect with ssh (pi/raspberry)
Some basic hints:
- If you need to change your mac address add clonedmac-address=XX.XX.XX.XX.XX to
/etc/NetworkManager/system-config/Wired Connection 1
- Hidden wifi needs bssid in Wifi Connection 1

PCSC
sudo apt-get update
sudo apt-get install build-essential subversion
sudo apt-get install pcscd pcsc-tools libpcsclite-dev libccid
libssl-dev
CCID supported card reader is hardly recommended
- armv6 linux, HW vendors has no precompiled driver
http://pcsclite.alioth.debian.org/ccid/
Run pcsc_scan to see it's working, test it with a card.

TvHeadend
Copy firmware of the dvb-t stick to /lib/firmware and
connect the tuner to the Pi.
On XBMC gui, turn on preinstalled tvheadend in the
“Programs” menu
Use your web browser on a machine to configure the
tvheadend service at port 9981.
