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.

(4)

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

(5)

Setup

Exit to console or connect with ssh (pi/raspberry)

Some basic hints:

- If you need to change your mac address add

cloned-mac-address=XX.XX.XX.XX.XX to

/etc/NetworkManager/system-config/Wired Connection 1

- Hidden wifi needs bssid in Wifi Connection 1

(6)

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/

oscam-svn

cd oscam-svn

make pcsc

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.
