Background On November 1, 2017, the Israeli broadcast authorities split Channel 2 into two channels, 12 and 13. To avoid unfair competition with the other channels, as channel 2 might lose viewers due to the confusion, channel 10 was moved to 14 as well. This requires a rescan of DVB receivers. The changes are rather [...]
Introduction This is a not-so-short tutorial which is intended to make the setup of a Live TV media center on Linux a bit easier, walking through the processing chain from the digital transmission signal to the picture on the screen. Quite naturally, things go from “general knowledge” to a bit more hands-on. The approach here [...]
Intro These are my jots as I installed Linux Mint 18.1 on a Gigabyte GB-BACE-3160 Compact PC with a 240 GB SSD hard disk and 8 GB RAM, for the purpose of driving my TV in the living room. Not all issues are solved yet. General notes Use ssh -X. It allows X-windows to open [...]
This is a lot of random jots as I set up Tvheadend. As it was a bit of a battle, things may not be consistent below. There are some details below specific to my own environment (e.g. LAN addresses). Environment: Linux Mint 18.1 running a 4.4.0-53-generic kernel, receiving DVB-T in Haifa, Israel with a HD-901T2 [...]
This is the information obtained with xrandr from the HDMI to AV converter (Composite Video + Audio on RCA plugs) shown above: Screen 0: minimum 8 x 8, current 1280 x 720, maximum 32767 x 32767 DP1 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y [...]
The problem Having A HD-901T2 DVB-T2 stick on a Linux Mint 18.1 running a 4.4.0-53-generic kernel, Tvheadend started painfully slow. It took more than a minute before the web interface was available. And here’s why: Mar 11 10:22:35 tv systemd[1]: Starting tvheadend.service… Mar 11 10:22:35 tv tvheadend[6019]: * Starting Tvheadend tvheadend Mar 11 10:22:35 tv [...]
Some (or all?) DVB adapters can be set to submit the entire MPEG-TS stream to the host, without filtering specific channels (actually, PIDs). This allows viewing more channel at a time. This is demonstrated below with ffplay, even though ffplay tends to get stuck when it goes to a live stream. It’s also not possible [...]
This is the successful version of a previous post, using a DVB USB stick that works, for a change. Fix this, or it will wobble Literally. The USB plug of this device is poorly designed, so the metal frame doesn’t attach well to female connector. As a result, every little vibration makes the USB stick [...]
These are messy, random notes that I took while setting up my little Raspberry Pi 3. Odds are that by the time you read this, I’ve replaced it with a mini-PC. So if you ask a question, my answer will probably be “I don’t remember”. Even though the Pi is cool, it didn’t supply what [...]
