Dreambox a Linux powered receiver

Dreambox a Open Source Linux Powered DVB Receiver

The Dreambox is a set top box decoder (STB) powered by Linux; Dreambox does not only offer DVB satellite receivers it also has a version of each model for terrestrial and cable digital television. Dreambox is produced in Germany by Dream Multimedia. Its main "feature" is its open code, meaning source code is available and can be modified by programmers under the GNU Licence model (General Public Licence), there are hundreds if not thousands of individual programmers and groups creating new applications and modifying existing ones all working for free, the only compensation is to push their Dreambox boxes further and to obtain the best performance out of these popular devices.

Dreambox receivers are right on the middle of the FTA game, they even have their own Conditional Access encryption system, known as DreamCrypt and software-emulated CA Modules (Conditional Access Modules - CAMs) available for many alternate conditional access systems. The Dreambox Linux-based software was first used by a company called Kirch Media for its pay-TV services.

Some models come with an Ethernet card that provide them with network connectivity; is easy to identify an ideal mix for "FTA" hunters: Third party programmers plus internet connectivity plus card sharing capability make this STBs the perfect device to "catch" Free to Air TV the one that is not REAL FTA (paid TV) of course; but do not get me wrong, all those cool features are extremely useful for REAL FTA fans as well.

Just imagine how handy is to own a receiver that you can modify at your will (obviously when you know how) and specifically in case that you decide to go for those modifications to your receiver in order to decode subscription TV without a subscription, but remember that third-party software for this purpose is neither officially endorsed nor supported by Dream Multimedia and will void the warranty...however unofficial websites, forums, programmers and groups are available everywhere.

Dreambox 7025+

This Dual tuner receiver is one of the most advanced Set top box available, it can be configured with any combination of two tuners:

  • DVB-S-Tuner (S stands for Satellite): TV and radio from your satellite dish it works with a frequency range 950 . 2150 MHz Signal Level - 65 dBm . - 25 dBm Signal-to-Noise Level 12 dB max. DBS-Tuner Input Connector F-Type female Input Impedance 75 Ohm
  • DVB-T-Tuner (T stands for Terrestial): TV and radio with antenna VHF-Channel: 2-12 (49...230 MHz) UHF-Channel: 21-69 (470...861 MHz)
  • DVB-C-Tuner (C stands for Cable): TV and radio over your digital cable Input frequency: 51...858 MHz Symbol rate: 1 ... 7 Mbaud/s Input impedance: 75 Ohm Tuner In/Out connector: IEC

You can, for instance, setup your receiver with a DVB-S and a DVB-T tuners to have the best of both worlds, while FTA enthusiasts may will prefer two DVB-S tuners instead, the main benefit of having two tuners in the same box is that user can watch a channel while is recording from another

The Dreambox 7025+ is powered by a processor AMD Xilleon 226 that integrates a 300 MHz CPU, graphics, dual high-definition MPEG decoder, conditional access, audio, USB, EIDE, PCI, memory controller, and a host of other I/O capabilities, all that power is controlled by enigma2. Enigma2 is a framebuffer based language for linux. Even though Enigma2 better performance is obtained by STBs, like 7025, it also works on regular PCs. Enigma2 is developed in Python programming language with portions written in C++. It uses the API LinuxTV DVB, which is part of a standard linux kernel.
