The biggest difference to a receiver "off the shelf" is likely to be the software. Because in Pingulux tinkers Linux operating system, which allows it, among other things, to equip the device through plug-ins with all sorts of additional functions. That way you can eg operate an HD + card, even though the device is actually certified for HD +. Advantage of this "non-certification" it is, for example, that the device is not on this stupid HD + -Restriktionen stops (recording ban, Timeshift limit etc). Theoretically you could receive -passende Plugins- vorrausgesetzt also channels that are actually grundverschlüsselt (eg ORF). However, this is a legal gray area, which is why I no longer want to go into it here.
The software itself is not yet mature 100%, but these every couple of weeks is improved via an update, which can be upload via LAN (connection to the domestic DSL router is always strongly recommended). Here are some points that I consider to be in need of improvement:
a) the boot time. If the device does a hard reset (eg if you had disconnected it from the mains), so it takes almost a minute, until the picture appears. A "warm start" standby, however, works in about one second.
b) Some functions can only be reached relatively cumbersome. In particular, I am thinking of the love that I use Teletext. To activate, you have to press all 3 buttons first. To deactivate again 2 keys. Here it would be useful to be able to prove the buttons on the remote free in order to achieve certain functions more quickly.
c) Furthermore, I have problems with the sound. Stations with AC3 sound are namely only output with audio on the TV, when you activate the options "Dolby Digital HDMI". The problem is that then the volume control on the receiver does not work anymore, that the volume does not change even if you press the volume button on the remote control. Another problem is rather the software itself owed: If you have zBgerade teletext or the EPG is enabled, the mute button on the remote control no longer works.
A small drawback is also the remote control. The fact is not very flexible in terms of alignment with the receiver. While it is sufficient for most remotely controllable devices, coarse to sight with the remote control the direction of each device, so the remote control of Pingulux wants to be pointed directly at the receiver. Whether this is due to the transmission power of the remote control or whether it is due to the construction of the IR module in the remote control, however, beyond my knowledge.
