In the following paragraphs, I'll try to make a brief comparison between one of the best selling digital satellite receivers which are currently available, and to see the distinction between the Dreambox DM800 HD, Dreambox DM500 and also the Openbox S9 receivers.
The most obvious difference between these 3 receivers is their dimensions. The Dreambox DM800 and DM500 have relatively exactly the same size, 195 mm (W) x 140 mm (D) x 40 mm (H) for DM800 and 195 mm (W) x 130 mm (D) x 40 (H) mm for DM500. Larger dimensions has got the S9 receiver. It's 300 (W) mm x 220 (D) mm x 56 (H) mm. As possible see, the Dreambox receivers tend to be smaller when compared to Openbox S9 receiver.
Now let's compare the external interface from the receivers. Dreambox DM800 HD has one S/PDIF optical output, one scart connector, one Ethernet and modem port, two USB and one eSata ports, one Dvi and something RS 232 port. The Dreambox 500 S receiver has much fewer ports. It's just one scart and something Ethernet port, one S/PDIF and something RS232 port and a pair of analog audio out ports and one analog video out port. The Openbox S9 receiver has 2 scart ports, 6 analog video out and audio out ports, one Ethernet and something HDMI port, one RS 232 and one usb port and no S/PDIF port.

The third reason for our comparative analysis may be the internal components comparison. The DM 800 HD has a high quality 300Mhz processor and it is designed with the Alps 801A M Tuner, which delivers clear HD video and sound. Additionally, it has an OLED display and one smartcard reader. The DM 500 however, has a weaker processor, with only 250 MHZ, and an older version of the Alps tuner. Additionally, it only has one smartcard reader. The Openbox S9 receiver has a standard tuner along with a regular Liquid crystal display and three smartcard readers. Just like the Dreambox 800 receiver, the Openbox has a fast 300Mhz cpu.
All three receivers are running Linux Operating System, all support multiple LNB-Switching (DiseqC), all have teletext, OSD and EGP support and the frequency range on all three models is 950 to 2150 MHz.
