Network performance & energy consumption of HDTV Dreambox DM 8000

[Zeppelin]

To HDTV movies over the network without being able to stream disturbances, a bandwidth of at least 2.5 MB / s data transfer rate required effective. Older Dreambox models achieve this throughput with difficulty. Then there is a DM 7020 with operation at a Fritz Box 7230 as the switch at around 2.5 MB / s read from the PC. Writing is merely gave a throughput of 1.5 MByte / s on the DM7020. The network interface of the new top model DM 80 000 Dream Multimedia has increased the throughput significantly. Via FTP in the test setup are writing 5.3 MByte / s possible. Attacks the PC read access to the Dreambox, increases the throughput to do to 7.7 MB / sec. When copying via Samba Shares and Windows Explorer data transfer rate is like reading the writing is 5.2 MByte / s. Thus, should the connection via a LAN cable, two parallel HDTV streams to the network without interference possible at all times.

The situation is slightly different when using the built-in wireless card. If the Fritz Box 7230 is in the immediate vicinity of the Dreambox DM 8000, SMB, 1.9 MByte / s in both directions of the maximum value. About a pure FTP connection in the test were reading from the Dreambox least 2.4 MB per second. However, the write speed and wireless internet access was via FTP with 1.5 MB / s surprisingly low.

Summa is the gamut of WLAN so that only a stopgap. It is enough even in the best case not to stream HDTV content. When streaming from PAL programs it is running out in practice over the wireless network, here it comes, depending on the quality of the connection drop outs. For the MP3 streaming and copying of movies on the PC for further processing, the living room friendly air cable is high enough at any time. Interesting for use as a file and media server , mostly 24 hours of the day is turned on, the power consumption. Compared with older models such as the Dreambox DM 7020, this has increased significantly in DM 8000th The DM 7020 is content to stand-by mode with around 10 watts. In case of access via network to the disk this value rises to 15 watts. likely lead to the Dreambox DM 8000, however you have to stand-by mode at 21 watts, with Target Disk Mode with 26 watts. Looking also still far away, the power consumption rises to about 30 watts.

Who are Dreambox DM 8000 at length one, they should absolutely with its network and connect Media Center to use as. The integrated network services in the firmware can be set up all comfortable and well run stable. The network throughput Dream Multimedia has done its homework. More than the measured 7,7 MByte / s for a 100 Mbit / s network is hardly possible. Thus, DM is the 8000 ideal as a central file and media server . Who wants to stream PC films should, however, a connection via the WLAN from the head to beat, for there is simply too slow 802.11g.

Too bad that the power consumption in standby with 21 Watts is down quite high. Euro 40, years so per tickers on the meter, twice as much as in older Dreambox models. But HDTV has now times its price in the DM 8000 with around 1,000 € for the basic unit (without hard drive, no DVD drive) does not fail just low. Even errands for which there is in the web interface are not suitable menu item to do a browser. Emergency emerges to make a virtual remote control and controls the Dreambox DM 8000 about it. Actually exhilarating to the Web Interface is that one can obtain about the current program and recorded shows streamed on the PC. To accomplish this stress-free, it must progress the open-source media player VLC on the PC must be installed. It is significant that when you install the plug-ins installed for the selected browser. Then with a snap can be viewed on the station list each program on the PC.
