About Dreambox DM800 HD se

History

The Linux-based production software originally used by Dreambox was originally developed for DBox2, by the Tuxbox project. The Dbox2 was a proprietary design distributed by KirchMedia for their pay TV services. The bankruptcy of KirchMedia flooded the market with unsold boxes available for Linux enthusiasts. The Dreambox shares the basic design of the DBox2, including the Ethernet port and the PowerPC processor.

Its firmware is officially user-upgradable, since it is a Linux-based computer, as opposed to third-party "patching" of alternate receivers. All units support Dream's own DreamCrypt conditional access (CA) system, with software-emulated CA Modules (CAMs) available for many alternate CA systems. The built-in Ethernet interface allows networked computers to access the recordings on the internal hard disks on some Dreambox models. It also enables the receiver to store digital copies of DVB MPEG transport streams on Network file systems or broadcast the streams as IPTV to VideoLAN and XBMC Media Center clients. Unlike many PC based PVR systems that use free-to-air type of DVB receiver cards, the built-in conditional access allows receiving and storing encrypted content.

In 2007, Dream Multimedia also introduced a non-Linux based Dreambox receiver, the DM100, their sole to date, still featuring an Ethernet port. It has a USB-B port for service instead of the RS232 or mini-USB connectors found on other models.^[1] Unlike all other Dreamboxes, it features an STMicroelectronics CPU instead of PowerPC or MIPS.

This is essentially a high definition version of the DM 600 PVR, featuring a single pluggable DVB tuner (S/S2, C or T), a 300 MHz MIPS processor, 64 MiB of Flash memory, 256 MiB of RAM and room for an internal SATA 2.5 in disk. It also features one DVI to HDMi Cable, two USB 2.0, one eSATA and one 10/100 Mbit/s Ethernet interfaces. It has an OLED display.

DM 800HD se was introduced in late 2010. The main differences of the DM800HD se compared to the DM 800HD are a 400 MHz MIPS processor, a HDMI connector and a color OLED display.
