Collaborate Disseminate
If you’ve ever thought about launching a high-altitude balloon, there’s much to consider. One of the things is how do you stream video down so that you — and others …read more Continue reading Balloon-Eye View via Ham Radio
In episode 96: Thousands of Disney+ accounts have been hacked, Black Friday and Cyber Monday scams to watch out for, and the latest on new Android camera exploits affecting Google and Samsung smartphones. ** Show notes and links mentioned on the show *… Continue reading Disney+ Hacked Accounts, Black Friday Scams, Android Camera Exploits
Were you aware that there’s a market for backpack-housed live streaming video systems, and that they can cost as much as $1600? Apparently these things are popular with social media moguls who want to stream themselves living their fabulous lives to people sitting at home watching on YouTube or Twitch. …read more
This past semester I added research to my already full schedule of math and engineering classes, as any masochistic student eagerly would. Packed schedule aside, how do you pass up the chance to work on implementing 360° virtual teleportation to anywhere in the world, in real-time. Yes, it is indeed the same concept as the cult worshipped Star Trek transporter, minus the ability to physically be at the location. Perhaps we can add a, “beam me up, Scotty” command when shutting down.
The research lab I was working with it the Laboratory for Immersive CommunicatiON (LION). It’s funded by NSF, …read more

Small aircraft with streaming video cameras are now widely available, for better or worse. Making eyes in the sky so accessible has resulted in interesting footage that would have been prohibitively expensive to capture a few years ago, but this new creative frontier also has a dark side when used to violate privacy. Those who are covering their tracks by encrypting their video transmission should know researchers at Ben-Gurion University of the Negev demonstrated such protection can be breached.
The BGU team proved that a side-channel analysis can be done against behavior common to video compression algorithms, as certain changes …read more

The Raspberry Pi is an incredibly versatile computing platform, particularly when it comes to embedded applications. They’re used in all kinds of security and monitoring projects to take still shots over time, or record video footage for later review. It’s remarkably easy to do, and there’s a wide variety of tools available to get the job done.
However, if you need live video with as little latency as possible, things get more difficult. I was building a remotely controlled vehicle that uses the cellular data network for communication. Minimizing latency was key to making the vehicle easy to drive. Thus …read more

In 1998, a Hong Kong telecom firm spent $1.5 billion trying to make video-on-demand happen. iTV was so ahead of its time that it beat Netflix’s DVD service. Continue reading Before There Was Netflix, Hong Kong Had the First On-Demand Streaming Service
Some people will tell you that YouTube has become a vast wasteland of entertainment like the boob tube before it. Live streaming doesn’t help the situation much, and this entry level webcam live-stream server isn’t poised to advance the art.
We jest, but only a little. [Mike Haldas] runs a video surveillance company that sells all manner of web-enabled cameras and wondered what it would take to get a low-end camera set up for live streaming. The first step was converting the Zavio webcam stream from RTSP (real-time streaming protocol) to the standard that YouTube uses, RTMP (real-time messaging protocol). …read more
