Netgem N7700 STB teardown

Elisa Viihde is a IPTV service sold by Finnish telecom operator Elisa. The system works so that you have a set-top-box that connect to your cable TV and your Internet connection. You can use the set-top-box to view both live cable TV signal, your recorded TV programs from IPTV video recorder (in “cloud”), pay TV though IPTV and rent digital movies.

Elisa has used over the years several different set-top-box models. Netgem N7700 and N7800 are the newest model being used. They have new features, but have got some mixed reviews from users. Here is view what is inside Netgem N77000.

    - wlan is USB stick inside device
    - there were no markings I could find in main CPU
    - I quess that the doughterboard on left next to antenna tuner could be DVB-C receiver IC (could make different versions for different TV standards quite easily)

    I want to know how to wipe my N7800 and install Linux Mint. Do you know how I can do that?

  5. Henri P says:

    Could somebody contact to Netgem and ask if they would support Linux community to create open-source OS for their system. N7700 is no more being sold by different vendors so this would make Netgem possible to “recycle” their hardware so device owners could easily re-use as a Linux mediacenter (with DVB tuner, IPTV streams etc).

    Most likely it is using Linux already (with QT frontend). So what’s the CPU in there? Probably ARM based? Could somebody (like box developers at Elisa) show output of: cat /proc/cpuinfo
    Where’s firmware and how it could be overwritten (with JTAG?)? How to access serial port, where are the pins?

    Linux Mint is PC operating system, not for embedded systems. It could be something like OpenWRT, eLinux etc.
    If you like to play with Linux Mint then you should buy Raspberry Pi 4 with DVB-T tuner HAT. It could do almost same plus much more.

    “Save the environment and use Linux” (on your old hardware).
    Regards, Henri
