Since I am frequently using the xenim streaming network service but I was missing out on the functionality to replay recent shows. With the wonderful functionality of Re-Live made available through ReliveBot I have now added this replay feature and I am using it a lot since.
Within the SONOS controller app it looks like this:
I am a frequent podcast live-stream listener. And being that I am enjoying the awesome service called xenim streaming network.
Any Podcast producer can join the xsn and with that can live-stream his own Podcast while recording. It’s CDN is based on voluntarily provided resources and pretty rock-solid as far as my experience with it goes.
Since I am a frequent user of this – and I’ve got that gorgeous SONOS hardware scattered around my house – I thought I need to have that service integrated into my SONOS set.
The SONOS system knows the concept of “Music Services”. There are quite a lot of them but xsn is missing. But SONOS is awesome and they got an API!
Unfortunately the API documentation is hidden behind a NDA wall so that would be a no-go. What’s not hidden is what the SONOS controllers have to discuss with all the existing services. Most of the time these do not use HTTPS so we’re free to listen to the chatters. I did just that and was able, for the sake of interoperability, to reverse engineer the SONOS SMAPI as far as it is necessary to make my little xsn Music Service work.
Step 1:Start your SONOS Controller Application and find out the IP address of your SONOS.
Click on “About My Sonos System” and check the IP address written next to the “Associated ZP”.
Step 2: Add the xsn Music Service.
By opening a browser window and browsing to: http://<your-associated-zp-ip>:1400/customsd.htm
When you’re there – fill out the fields as below. The SID is either 255, or if you used that previously, something between 240-253. The service name is “xenim streaming network”. The Endpoint URL and Secure Endpoint URL both are http://xsn.schrankmonster.de/xsn
Set the Polling interval to 30 seconds. Click on the Anonymous Authentication SOAP header policy and you’re good to go. Click on “send” to finish.
Step 3: Add the new Music Service to your SONOS Controller.
Click on “Add Music Services” and click through until you see “xenim streaming network”. Add the service and you’re set!
p.s.: It’s normal that the service icon is a question mark.
When music just does not cut it and you need to concentrate or sleep. Well you need rain. To the rescue comes an entire internet radio station dedicated to bring the best rain showers directly to your speakers:
In my case it’s just partly do-it-yourself: Michael and Peter did the cable soldering and I wrote the software that controls the serial interface to the PMR sender/receiver.
My gateway is on PMR channel 5 with no CTCSS configured in the Campus area of the TU-Ilmenau. A gateway is only just a PMR radio connected to a PC which is logged into a Teamspeak server which is connected to several other gateways (citizen radio / PMR / …)
So if you talk within the range of my gateway you’ll be heard in more than 24 areas across germany over PMR and citizen radio.
One toolset which was particularly useful is the VU-Meter tools. You can use them to monitor your input/output ports and tune them for perfect modulation. You can get them here and they look like this:
Since the cable soldering was one piece of craftsmanship a picture of the radio and the cable:
the computer side of the interface
the radio side of the interface
If you want to connect from outside the range of the PMR you should go to the homepage of Freies Funknetz and get all the necessary information there.
The internet makes things possible some people dreamt of for years. One of these things is the possibility to stream live-voice-chat over the internet. Many people used the citizens’ band radio – CB radio – for the last decades:
“Citizens’ Band radio (CB) is, in many countries, a system of short-distance, simplex radio communications between individuals on a selection of 40 channels within the 27 MHz (11 meter) band. The CB radio service should not be confused with FRS, GMRS, MURS, or amateur (“ham”) radio. Similar personal radio services exist in other countries, with varying requirements for licensing and differing technical standards. In many countries, CB does not require a license and, unlike amateur radio, it may be used for business as well as personal communications.”
For several years now there is a group of people from virtually everywhere in germany who connect their CB radios to the internet – they link their “gateways” together using a software normally used by online gamers called “TeamSpeak”. All you have to do to take a look is to read this short how-to and follow the steps.
Here’s a sneak-peak at the current status of the server:
There’s even a livestream available (but sometimes not working):
Oh joy! It seems that the public-law radio and tv channels in germany start to think about the possibilities the internet can bring us.
One of these channels is the WDR radio which just started it’s internet push: the WDR RadioRecorder is available now – and it allows you to select a broadcast and mark it to be recorded. Actually it sounds a bit strange because I tend to think that the people at WDR radio don’t really get it when it comes to “on-demand”. Recording is not on-demand… The tool is available for Windows only at the moment and looks a bit like iTunes…
Namenlos wrote about how almost everything is held together at this years ISWI technically. Well he even draw something neat to look at and say “Look, that we did!”
“Die Audiostrecke wird mittels 6 Behringer Ultragain Pro-8 Digital ADA8000 aufgebaut. Diese Geräte nehmen 8 Kanäle Audio via XLR entgegen und setzen die auf eine ADAT-Verbindung über ein TOS-Link-Kabel um. Da die TOS-Links nur 10m weit gehen hängt an jedem Behringer ein ADAT-Extender, der das ganze gleich auf Glasfaser umsetzt. So kommt der Ton vom Studio zur Regie und zurück. Zusätzlich liegen noch 5 Strecken Video (so ein Fernsehsender ganz ohne Bild is ja auch nix.). Zum Abschluss verteilt in der Fischerhütte nochmal ein HP Procurve 2524 ein bischen Netz an die Surfterminals und die Leute vom ebenfalls dort beheimateten L.i.g.h.t. Projekt.”
And then deka came and created another drawing of the Live Streaming infrastructure:
“From June 1st to 10th, a group of approximately 50 students of the university daily presents a TV show about this get-together with all its events and participants. Most of them are members of the student broadcast station called iSTUFF, a department of the Forschungsgemeinschaft elektronische Medien e.V. (FeM e.V.). The ISWIsion studio is located in the Fischerhütte at Langewiesener Straße 22. The former glass manufactory is being remodeled into our media centre for the traditional ISWI. All shows will be broadcast live and in English via internet stream, campuscable on channel 3 and – for the first time – via DVB-T on channel 23 in the whole city zone of Ilmenau.”
