Haivision and Wowza form Open Source SRT Alliance

At IBC 2013, we demonstrated the first early preview of a new network protocol called SRT in the HaiGear corner at our Haivision booth. While HaiGear demos are always very forward looking and often just proof of concept or design ideas, this one went a long way.

Doing live interview filming in a hotel suite outside the IBC complex, we transmitted the live streams over the public internet onto the show floor, displaying it on a TV at our booth. In order to achieve this under extremely challenging network conditions with over 5% packet loss, we combined our brand new network protocol SRT with the not even yet standardized HEVC video codec. Combining both technologies proved to be the perfect combination to get around first mile issues under extreme conditions often faced in live event productions.

Coming from a protected network world and typically utilizing the UDP protocol for lowest latency transmission of high quality video over local area networks, Haivision’s move to multi-site enterprise installations required a new solution to take care of packet loss, jitter, delay and security when trying to send those streams from one site to another one over the public internet.

SRT – Secure Reliable Transport – is a Reliable UDP based and completely content agnostic network protocol for low latency audio, video and general data transmission over unreliable networks such as the public internet. It recovers packet loss up to very high rates, encrypts the stream with standard AES 256 (or 128) and carries real-time behaviour from the sender to the receiver, which is extremely important when streaming variable bitrate streams, as often used for video transmission.

SRT is implemented as low level C/C++ library, builds on Windows, Mac OS X and Linux, has a very low footprint and can therefore be used on a wide range of platforms, including embedded devices, mobiles phones as well as workstations or servers.

At NAB 2017, we announced the SRT Alliance, initiated by Haivision and our friends from Wowza with the goal to thrive the adaption of the protocol, get the attention of the Open Source community and utilize the creative energy of talented developers out there.

The amazing feedback we received from the industry during the show surpassed our expectations and is super exciting to everyone involved 🙂 What a ride so far!

New Szalóky Arrows

When you are an Archer, you frequently need new Arrows. Things just happen. In the optimal case, you learned and find the time to make your own. No doubt. If not, as we me so far, you need to find your sources.

I tried a lot of arrows, cheap ones from eBay, real medieval original style handcrafted Arrows from the Viking Market in Schleswig or Haithabu (Hedeby) for 25 Euros a piece and mid-priced Arrows from other markets. To make this clear first, the original style handcrafted in Germany ones totally rock. But I don’t want to use them for my everyday training, as every breaking Arrow makes you cry …

Aside of my Longbows, I built a couple of Bows for Kids. Mathis has his own collection of Arrows and most of them are relatively new. There is a single one though, which we have for a lot of years now and it just won’t die. On the Shaft, there is an Inscription saying “Szalóky Kelemen“.

Yesterday on the Medieval Festival in Hohenwestedt I found a Booth with a Guy from Hungary, selling Szalóky Arrows. I had a quick look and the quality is the same awesome quality of the old one we got. I grabbed five for me and one for Mathis. I paid 35 Euros all together!

Coming home and shooting them a couple of times, I slapped myself not to have taken two dozen of them home …

No, it’s not the 25 Euros Viking Arrow quality we are talking about, but we are talking about 80% of the quality for 6 Euros! I’ll try to collect more of the high end ones over time for the days when I dress up and go to Viking events, but for my daily training, I’ll go for Szalóky from now on.

Ok, ‘nuff said, here are some pictures (Click on them for High Res):


The Kids Arrow in the top left picture is the old one we used for quite a couple of years. The one below is one of the new Adult Arrows with self-nock.


Getting Ready to try them with the English Longbow Smile

Individual Maple Longbow

I just put linseed oil and beeswax on my individual version of a longbow, made from maple wood.

The wood is far from perfect, but that’s the fun when it comes to bow building 🙂


The tiller is a bit too stiff on the right side, but I had doubts to weaken the knot regions more.


A lot of knots on the right side.


And some nice color transitions.


Some knots on the left arm.


I am using a hold without leather here.
