Hospitality TV, offering an excellent TV solution with high-quality broadcasts and a selection of the best channels, is an essential part of hotel service.
The number and quality of channels create a positive impression on guests. However, this is where the challenge arises. Hotels need to either modernize their existing TV network or design a new one, finding a balance between equipment costs and required services. We suggest considering the Astra software, which boasts powerful and flexible features when used in conjunction with the RESI DVB-C FSM modulator. In this article, we will explore the pros and cons of such a solution and walk through the steps to set it up.
For receiving satellite channels you may use any DVB-S/S2 adapter with drivers for Linux.
Most popular DVB receivers are:
In this article, we consider simple steps on How to set up Astra for DVB-C Modulation using RESI DVB-C FSM 8.
Short description:
According to that, we may calculate how many channels we may put on a single transponder and on all available transponders:
Approximately we can get 8 channels at one transponder, multiplied by 8 transponders we can get up to 64 channels in your DVB-C network. This is combination of channels may be different, it is up to your needs.
Hardware:
Software:
First of all, we need to prepare our server machine and install Linux and Astra. Information about Ubuntu installation could be found on the official web site
Astra installation is simple – just copy a single binary file to your server. Here, in detail, you may find how to Install Astra
Quite often customers forget to configure their Adapters before the next steps. So be sure that you have DVB card drivers installed on the server. Here are a list of useful links for that:
Now is the time to configure all our Adapters and find channels, which we want to Modulate over RESI DVB-C. List of all articles about channel receiving available at Astra Cesbo page: Receiving with Astra.
To configure receiving channels from satellite we recommend to having a look at these articles:
Below provided screenshot of example adapter settings:
When we figured out how to configure our Adapters, we may make a scan of the required Transponder (frequency) and append channels to Astra by selecting all the programs you want to add.
MPTS is a Multi Program Transport Stream (or multiplex) is a stream containing several services (programs). It is used to transfer channels to ip-qam/ip-asi modulators and multiplexers. Below are screenshots of most general configuration pages
In the SDT settings should be provided all information about channel:
In the NIT settings provide information for DVB-C transponder.
At this point, we have already found and added all the necessary channels in Astra, created a New Stream, and configured the MPTS, which should be sent to the modulator. To configure the Output signal to the RESI DVB-C modulator we need to know the Number of RESI adapters in the system.
On the server console find the card number and modulators using the command:
find "/dev/dvb" -name "mod*"
In the output - we get the number of the adapter and its modulators like:
/dev/dvb/adapter0/mod0
adapter0
mod0
Now it is a turn to configure the Output signal to the RESI DVB-C modulator in the MPTS settings
As a result, we should get a fully configured Stream, as shown in the screenshot:
With Astra, you may Analyze the quality and stability of transport streams. Export statistics and events to external systems like Zabbix or Grafana.
Also at any time you may open Astra Web Interface to simply check out the Dashboard. Here you will see already configured Adapters, created Streams, and some useful options like signal strength/quality, bitrate at channels, and so on.
With these simple steps, we have set up our Stream. Now we have the channels converted and modulated with the RESI DVB-C FSM modulator.
The best way to check the output signal is to use an analyzer. There are many different models from many manufacturers. For example, Telestar:
Also, we can connect the coaxial cable from RESI to the TV set, and in the TV settings make a new DVB-C channel scan, either Full Scan or Network Scan (or specify the scan parameters manually). Channels search settings fully depend on the TV manufacturer, but in general, they are very similar.
