Some background: RTP is used primarily to stream either H.264 or MPEG-4 video. RTP is a system protocol that provides mechanisms… View Article Details

It’s a great programming environment, but since it’s also rather new, there’s a lot of tribal knowledge still… Details
Howdy Pierce The Importance of Encrypting Video Over IP Video By Howdy Pierce I just read a report of a new IP security vulnerability being demonstrated today at the DefCon hacker’s conference in Las Vegas. The new hack has two components: 1. The attackers are able to view video being streamed across a network, and 2. The attackers are able to use a man-in-the-middle attack to insert video controlled by the attacker to a video decoder somewhere on the network. The linked video shows viscerally how an attacker could foil a security/surveillance video system — a modern-day Thomas Crown Affair. Details
Mike Perkins Power Measurements With the DFT Signal Processing By Mike Perkins Many of the systems we work on here at Cardinal Peak employ analog-to-digital conversion in one form or another. It seems like almost invariably some analog signal needs to be digitized or “sampled.” Sampling is the process of periodically looking at an analog signal at some sample rate, and then converting each measured value into… View Article Details
