Video Compression Overview Design How-To 2/8/1998 Post a comment This short article reviews the four families of compression algorithms used in nearly all coders today and dicusses the most common DCT in a little more detail. The major intra-frame and inter-frame approaches are outlined to help the reader understand some of the differences between the many video codecs used in different applications today.
An Overview of Video Compression Algorithms Design How-To 2/3/1998 Post a comment Have you ever wondered what the difference is between JPEG and MPEG. Or MPEG-1 and MPEG-4. Well this article takes you through video CODEC land, with an explanation of all the major compression/decompression approaches used in still image compression, desktop multimedia, broadcast TV, and videoconferencing.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
