A little while ago, around the end of last year, we had the pleasure of supporting hsf Studentenradio e.V. with a special anniversary gift: an IP-4c audio codec, provided on the occasion of their 75th anniversary.
Since then, hsf has already shared their own experience and impressions in a LinkedIn post, which we were very happy to see and appreciate greatly.
The IP-4c was supplied to help improve the audio link between the studio and the transmitter site at Vogelherd. The existing connection, based on a shared IP microwave link, is prone to occasional packet loss — a challenge the IP-4c addresses with features such as FEC, RIST, and SRT, resulting in a more stable and robust transmission.
Additional features like detailed packet loss statistics support ongoing link optimization, while dual streaming enables redundancy via a separate network. In the event of a failure, the integrated backup switching allows automatic fallback to a web stream or file playback.
Even though the Christmas lights are long gone, we’re still very happy to have supported hsf Studentenradio e.V. and wish them continued success in their anniversary year and beyond.
