Of course, this is with the cost that we cannot use or embed standard components like a web browser without much work.” The limited 8MB Flash memory was a reason for not using a generalized GUI library. This offered the necessary features and a nice C++ interface “without being bloated like QTE.” Domke notes, “I don't want to say that the alternatives were not good - but they just didn't fit into 'our way' for the application. Instead, the company built its own system, based on the standard Linux framebuffer. I have heard that a non-devel will boot, including network, ide, etc.”ĭMM chose not to use an off-the-shelf GUI/windowing system such as XFree86, Qt/Embedded, or Microwindows. “Basically, an unpatched linuxppc-2.4-devel.

It has a deep standby power-saving mode that uses only 1.2 watts.ĭMM provides a complete list of features and specifications on its Web site.Īccording to Felix Felix Domke, Software Developer with DMM, the DM7000 runs a linuxppc-2.4.2x-devel kernel, with some minor patches for the Memory Technology Device (MTD) mapping, among other things. The device offers a maze of interfaces, including serial, parallel, USB, IrDA (not high data-rate - just for remote control), digital I/O (IIC), LAN (100Mbps Ethernet), wireless Ethernet, Audio AC3, RGB, FBAS, YPbPr, audio analog, CI-Interface, SmartCard reader, and CompactFlash Reader. It can store video on an internal hard drive (not included), on CompactFlash (via an internal CompactFlash connector), on USB memory stick, or on other external devices.ĭreambox DM7000 front and back panels.

It has 64MB of RAM, and boots from 8MB of internal flash memory.

The Dreambox DM7000 runs on an IBM STB Chip Pallas Pro processor clocked at 250 MHz for 350 million instructions per second (MIPs). Channels - Satellites - Low Noise Block-downconvertor (LNB).

Channels (automatic search, manual search).

The device's open-source nature has resulted in availability of dozens of plugins, from various CA modules to games and installation helpers. It includes a connector for an internal hard disk, a compact flash reader, and an on-screen display and remote control.

The DM7000 features a Common Interface (CI) slot with the same form-factor as PCMCIA (but not the same handling) for conditional access (CA) modules, enabling reception of clear and encoded ASTRA and EUTELSAT digital video broadcasts.

A minimalistic, GPL'd Linux-based software implementation has made the DM7000 popular with Linux programmers and TV device hackers. It is implemented using IBM's STB04500 set-top box chipset, which provides the necessary DVB functions like transport stream demultiplexing and MPEG2 decoding inexpensively. The Dreambox DM7000 from Dream-Multimedia-Tv (DMM) is a $395 Linux-based digital radio and digital TV (DVB) satellite (or cable) receiver with digital video recorder (DVR) functions and PC connectivity.

Our infographic provides some answers to who middle school students are, how they learn, and classroom strategies to make sure they stay engaged at this extremely critical time in their learning lives. To reach and teach the middle school math mind, understanding its inner workings and leveraging current best practices just makes sense. As 13-year-old Logan LaPlante described in his Ted Talk Hack Schooling Makes Me Happy, “Neuroscientists say that the teenage brain is pretty weird: our prefrontal cortex is underdeveloped, but we actually have more neurons than adults, which is why we can be so creative, and impulsive, and get bummed out.” Truer words were never spoken around this subject.
