Linux stick for tv

The best supported DVB-C USB-Stick for Linux / tvheadend in 2018

my journey of finding the right TV Stick for my tvheadend setup finally came to an end.

And to watch and record 2 channels simultaneously I bought 3 of them which are working great.

My DVB-C USB-Stick of choice is now:

I use this 3 channel splitter to connect three of those pctv-sticks — https://www.amazon.de/gp/product/B00H6G2Z86

Somehow it was a long journey and I wasted some money on other sticks which didn’t work with dvb-c or with linux in general.

Usage

Install

I read in two places about those sticks, so I got two recommendations about which firmware file I needed. I just installed both and it works great.

So start off by downloading those two firmware files

• dvb-demod-si2168-b40-01.fw
  • https://github.com/OpenELEC/dvb-firmware/blob/master/firmware/dvb-demod-si2168-b40-01.fw
  • sha256sum: 8507536630d75a316d0719d6b95c04b90c36baa5b457ad457c9bacadafcef134
  • https://github.com/OpenELEC/dvb-firmware/blob/master/firmware/dvb-demod-si2168-02.fw
  • sha256sum: 5bbcfee4a0dbd55ea9d88d6b7d618afed5937a1f02962f14cdf707e108895cf7

  I installed both, but you might only install one

  Copy both firmware files to /lib/firmware

  Update: After figuring out with a reader of this blog why his stick didn’t work as expected we found the following:

  • it seems that dvb-demod-si2168-b40-01.fw is the right and only firmware
  • this file has to have 8507536630d75a316d0719d6b95c04b90c36baa5b457ad457c9bacadafcef134 as sha256sum — check it!

  Run dvb-fe-tool to see supported modi

  Multiple Adapters

  you can use a different adapter by it’s number (default: 0)

  dvb-fe-tool -a 1 # shows adapter 1 dvb-fe-tool -a 2 # shows adapter 2 

  to use a frontend other than 0, you can specify it with -f

  More

  Good Alternatives

  I can also recommend the Suntek MediaTV Pro DVB-C USB Sticks.

  I used it for serveral years — but unfortunatley after I moved I wasn’t able to recieve all channels my TV was able to recieve.

  So this journey began and I was searching for an alternative solution.

  Sunteks drivers work very well with linux, and they have great support for several processor architechtures and the driver runs in the userland!

  So it might also be a great choice!

  Устанавливаем Linux (Armbian) на ТВ бокс

  Если вести речь о энергоэффективных устройствах, то ARM64 архитектура себя отлично зарекомендовала. На рынке существует огромное предложение устройств на данной архитектуре. Но ценник при запросе определенных параметром стремительно растет вверх. Озвучим наши требования: ARM64, 1Gb ОЗУ и 8GB SSD или NAND. Естественно увеличение параметров в большую сторону приветствуется. Обратившись к рынку ТВ приставок — я вижу предложения от 1000р, что в 2-4 раза дешевле плат для разработчиков. Выбор пал на Х96 приставку

  За 1000р я получил ужасный ТВ бокс, но отличный конструктор. Блок питания и клавиатура, а также HDMI кабель шли в комплекте. Прикладываю подтверждение, так как никто не поверит иначе.

  Получив включил, посмотрел на тупящий андроид, выключил. Разобрал.

  В профильной теме Armbian на ТВ бокс находим нужны йобраз и скачиваем. Я скачал Armbian_20.11_Arm-64_buster_current_5.9.9.img.xz

  Заглянув по адресу https://www.debian.org/releases/ я вначале купился на bullseye релиз, не прочитав фразу:

  This release started as a copy of buster, and is currently in a state called testing . This means that things should not break as badly as in unstable or experimental distributions, because packages are allowed to enter this distribution only after a certain period of time has passed, and when they don’t have any release-critical bugs filed against them. Please note that security updates for testing distribution are not yet managed by the security team. Hence, testing does not get security updates in a timely manner. You are encouraged to switch your sources.list entries from testing to buster for the time being if you need security support. See also the entry in the Security Team’s FAQ for the testing distribution.

  Позже я поплотился за это и позже решил выделять отдельное время для игр с тестовыми образами. Для более менее стабильных систем я выбрал стабильный образ от debian. Позже мы устанавливаем образ на диск и читаем инструкцию:

  How to run these images on the Amlogic platform .
  Now all images Armbian and LE has all the files for activate the multi-boot. Anything addition to download and copy to media is not required.
  1. Download the image for your device
  2. Unpack
  3. Burn the image on the medium
  4. Configure in the file (uEnv.txt) launch parameters for the desired platform and model (uncomment the desired lines and comment out or delete unused ones)
  If universal multi-upload has not yet been activated on this device, you need to activate it once. There are several options for activating multi-loading.
  — Connect the prepared media to the device and turn on the power, boot into Android
  — Open the app «Update&Backup»
  — Click on «Select» local update and chose the file on the removable media aml_autoscript.zip
  — Start «Update»
  — System will reboot twice and start running the system from external media.

  На последних образах изменились правила:
  Pay attention. Starting from version 20.08 (20200814), the configuration order for the used DTB changes.
  Please note that the algorithm for initial configuration of the system for startup has changed. Instead of a file «uEnv.txt», the file «/extlinux/extlinux.conf » is now used. The rules for editing a file remain the same.
  All Amlogic models now need the «u-boot.ext» file.
  Before launching on Amlogic, you must copy or rename one of the existing files «u-boot-*» to «u-boot.ext».
  For s905 (not X) — used u-boot-s905
  For s905x and s912 — used u-boot-s905x-s912
  For s905x2 and s922 — used u-boot-s905x2-s922

  — Теперь устанавливаем образ на SD карту.
  — Открываем BOOT раздел на SD карте и переименовываем файл u-boot-s905x-s912 в файл u-boot.ext(на старых версиях этого делать не требовалось), затем в папке extlinux редактируем файл extlinux.conf (убираем ненужное и раскомментируем нужное). Для своей приставки я использововал meson-gxl-s905x-nexbox-a95x.dtb
  — Вставляем SD карту в приставку.
  -У меня загрузка начинается сразу, но я использую старый образ. Если загрузчик на приставке не обновлен, то заходим в обновление и выбираем обновление на флешке. После его установки первичная загрузка становится с флешки. Но в новых инструкциях рекомендуют зажать кнопку сброса, которая находится внутри разъема AV и включить питание приставки. После того, как на HDMI пойдет сигнал, отпустить кнопку сброса.

  При желании можно установить Linux в приставку и затереть Android, что я успешно и сделал. Если что-то пошло не так, то:

  5 easy steps to Install Linux on Android TV and firestick

  Today Almost every television comes with builtin Android OS, but the problem is that they are only limited for entertainment.

Since none of the browsers provide a desktop-like experience. But by installing Linux you could download firefox, chromium, and many more Linux applications, and also you can use it as a PC.

  In this article, we are going to use 5 apps but they are not sorted in any order

  Install Linux without rooting

  Install Linux applications

  Termux: Termux is a terminal emulator that provides a Linux environment without rooting. it is a free app available on the play store.

  Vnc: virtual network computing is software that enables you to control one computer from another device. usually, it is not secure since it transmits unencrypted data over the network. by running vnc server you can interact with the graphical environment. it provides a desktop-like experience

  SSH : secured shell is similar to vnc but it transfers encrypted data over a network. And it is also faster than VNC

  XSERVER XSDL: It is an android app which is the complete implementation of xserver. It gives various options on display, mouse, keyboard, video, etc

  Desktop environment: While installing Linux on android using any method the most confusing part is selecting the desktop environment, some environments are lightweight, some are resource-heavy but contain many features. below are some common desktop environments

  xfce: This is a lightweight desktop environment with less resource utilization and comes with good features. It is also beginner-friendly

  Lxde: Lxde stands for lightweight X11 desktop Environment is a lest Resouce hungry and faster when compared to others it works well with the devices with least ram

  How to install Linux on Android tv or firestick using userland

  Installing Linux with userland is very easy you don’t need another app it has a built-in terminal. This app is a replacement for the GNUroot which only works on lower versions of android

  It is easier to install Linux on android tv or firestick. For firestick, if you want to get rid of the on-screen keyboard best idea is to install Linux on it. But the performance of firestick is not good as compared to the android tv box. You could convert an android tv box into a PC by installing Linux OS on it.

  Estimated time 25 minutes

  Download Userland for play store

  You can download Userland from Playstore by clicking the link below or directly from the web if your smart-tv doesn’t support apps from play store
  If you installed an alternative app store for tv (Aptoide tv), you can install from it

  Select the required Distro

  UserLand supports 5 distributions namely Alpine, Arch, Debian, Kali, Ubuntu. select the one which you like and give userland storage permission

  Create Username and Password

  after giving storage permission. The dialog will appear asking you to fill the required information, which consists of username and password

  Select the connection Type

  you will get three options to select the connection type. I would prefer SSH. since it transmits encrypted data, you can also choose XSDL if it supports your version. After selecting Required Assets will be downloaded. Don’t worry about which to select, It can be changed later

  Update and proceed by selecting required options

  After downloading assets it will open up a terminal asking for the password that you have created at the begging and press enter. Required files will start downloading. After the process update and upgrade the files and database by entering
  apt update && apt upgrade

  Starting the desktop environment

  This is the last step where you launch the desktop environment
  You need to download any of these apps
  1. VNC viewer
  2. Xserver xsdl
  I am going to use Xserver xsdl since it is faster than Vnc
  First, open the app xserver xsdl and proceed it till a blue screen with white text as shown in above
  Now return to userland without closing xserver app and enter the below command export DISPLAY=:0 PULSE_SERVER=tcp:127.0.0.1:4713 startlxde & If the above command doesn’t work leave a comment below I will help you
