# RadioVIS Demo Application
## Introduction
RadioVisDemo is a demonstration application for RadioDNS and RadioVIS. RadioVIS
is the visualisation protocol that forms part of the RadioDNS suite of
application protocols, also known as Hybrid Digital Radio (DAB, DRM, RadioDNS)
Slideshow, defined in the following ETSI standards:
* [ETSI TS 103 270 v1.3.1 - RadioDNS Hybrid Radio; Hybrid lookup for radio services](https://www.etsi.org/deliver/etsi_ts/103200_103299/103270/01.03.01_60/ts_103270v010301p.pdf)
* [ETSI TS 101 499 v3.1.1 - Slideshow](http://www.etsi.org/deliver/etsi_ts/101400_101499/101499/03.01.01_60/ts_101499v030101p.pdf)
Please visit for more information about RadioDNS, and
to learn more about this project,
and to obtain the latest release of this
software.
## Installation
RadioVisDemo is a Python application and requires several dependencies to be
installed.
### Ubuntu
On Ubuntu, install Python 3, pip, and the GTK development libraries, then
use pip to install the dependencies:
```bash
sudo apt-get install python3 python3-pip libgtk-3-dev
pip3 install -r requirements.txt
```
Alternatively, you may be able to install a pre-compiled version of wxPython:
```bash
sudo apt-get install python3 python3-pip python-wxgtk4.0
pip3 install -r requirements-ubuntu.txt
```
### Windows
On Windows, download and install Python v3.5 or later from
, then use pip to install the required
packages:
```bash
pip install -r requirements.txt
```
### Mac OSX
On Mac, you can use pip to install the required packages:
```bash
pip3 install -r requirements.txt
```
# Running RadioVisDemo
To run the application, enter the following at a command prompt:
```bash
python3 radiovis_demo.py
```
The default setting in the **Domain** field is `radiodns.org`. Change this option
to perform radio station DNS lookups against a different domain, which is useful
for testing RadioDNS services during development.
Select a RadioDNS hostname in the **Hostname** field. The **Local Stomp Server** entry
allows testing of a RadioVIS service running on the local machine (localhost,
port 61613).
Press the **Resolve** button to perform a DNS CNAME lookup on the selected hostname
and then an SRV record query for available RadioDNS services (RadioVIS, RadioTAG,
and RadioEPG). The results are shown in the **CNAME** and **Services** fields.
If a RadioVIS service is available, select this from the **Services** list and press
the **Connect** button. The options next to the **Connect** button allow HTTP requests
and the Stomp connection to be routed through an HTTP proxy. Proxy settings are
obtained from the `urllib.getproxies()` method, which returns the system proxy
settings (the `http_proxy` environment variable or Internet Explorer settings in
Windows). A proxy server should not be used if connecting to a service on the
local machine.
Once connected, the following fields show information received from the RadioVIS
service:
* The **Log** field shows status messages and details of all Stomp messages
received.
* The **Messages** field shows the history of received RadioVIS TEXT messages.
* The **Image URL** field shows the URL of the image from the last received
RadioVIS SHOW message.
* The **Link URL** field shows the hyperlink from the last received RadioVIS SHOW
message.
* The **Image** field shows the image from the last received RadioVIS SHOW message.
* The **Text** field displays the last received RadioVIS TEXT message.
## Configuration
The RadioVIS demo application uses several configuration files, in the `conf`
directory:
### radiodns_domains.xml
This file contains a list of domains against which DNS lookups
for radio stations can be performed. By default, this list includes
`radiodns.org` (for live services) and `test.radiodns.org` (for test purposes),
but you can modify this list to refer to your own domain in order to test
your own RadioDNS services before making them available via radiodns.org.
### radio_stations.xml
This file contains a list of radio stations and their associated
broadcast parameters, which are shown in the **Hostname** field. Please read
the [RadioDNS documentation](http://radiodns.org/) for details of the
broadcast parameters.
If you'd like to add your radio station's details to this least, please
send us a pull request.
### radiodns_services.xml
This file contains a list of the RadioDNS services and SRV
record names, which are queried when the **Resolve** button is pressed. At
present these are RadioVIS, RadioTAG, and RadioEPG.
### test_radiovis_services.xml
This file contains a list of test RadioVIS services that
the application can connect to. Each `test_radiovis_service` element should
contain the following entries:
* `name`: The name of the test service name, for display in the user interface.
* `hostname`: The hostname of the computer that runs the RadioVIS Stomp
service.
* `port`: The port number of the RadioVIS Stomp service.
* `text_topic`: The topic name for text message notifications.
* `image_topic`: The topic name for slideshow image notifications.
## Tests
The `test` directory contains unit tests. To run the tests use the following
command:
```bash
nosetests
```
## Limitations
This software has a few limitations:
* The software uses the system proxy server settings (the `http_proxy`
environment variable or Internet Explorer settings in Windows), and these
are not configurable within the program.
* In the handling of RadioVIS SHOW messages, the trigger time is not used,
and the image is always shown immediately.
* Error and redirect statuses are not handled when retrieving images over HTTP.
* STOMP connections cannot be routed via a SOCKS proxy (fixing this requires
changes to the stomp.py module).
