On February 21st, 2020 at 3 PM CT // 9 PM GMT: Join us as to learn more about Embedded Video Using the UltraZed-EV with Daniel Rozwood from Avnet:
The UltraZed-EV Starter Kit is a complete platform for prototyping and evaluating embedded video processing systems. The presenter for this webinar, drozwood90 is an UltraZed-EV Project Engineer at Avnet and he's going to go over the hardware, development environment, reference designs, and demo the video-centric UltraZed-EV. The UltraZed-EV is what is known as a system on a module(SOM) that is designed specifically for embedded vision applications. The UltraZed-EV (Embedded Vision) platform adds support for 4K H.264 / H.265 hardware video codec capable of simultaneous encode and decode. High Efficiency Video Coding (HEVC), or H.265, is a video compression standard improves coding efficiency substantially compared to its precedent, the Advanced Video Coding (AVC), or H.264. HEVC uses efficient coding by encoding video at the lowest possible bit rate while maintaining a high image quality level. The UltraZed platform is ideal for multimedia, Advanced driver-assistance systems (ADAS) for Automotive, surveillance, and other embedded vision applications.
This webinar should be of interest to anyone who loves video, especially high resolution video. What people are used to dealing with, when streaming 4K video is H.264 (also called AVC - Advanced Video Coding) It is the industry standard for video compression that allows for the recording, compression, and distribution of digital video content. The blockiness you may have noticed while attempting to stream your high resolution video over a network that can't handle it is called marablocks. It is a block-oriented, motion-compensation-based video compression standard. Macroblocks typically consist of 16x16 pixel samples, that can be subdivided into transform blocks, and may be further subdivided into what are known as prediction blocks.
HVEC is the improved standard that allows you to further reduce file size, thus reducing the bandwidth required for your live video streams. Unlike H.264 macroblocks, H.265 processes information in what’s known as Coding Tree Units (CTUs). Whereas macroblocks can span 4x4 to 16x16 block sizes, CTUs can process as many as 64x64 blocks, giving it the ability to compress information more efficiently. In addition to the larger CTU sizes, HEVC also has better motion compensation and spatial prediction than AVC does. H.265 compatible devices require less bandwidth and processing power to decompress data and do high resolution streaming. This also means that with the right hardware, 4K video streaming is now possible over common network speeds.
