On June 19, semiconductor IP supplier CAST announced that it had optimized the functions and performance of its JPEG encoder IP core.

System designers now have two rate control options to choose from for debugging specific applications of JPEG compression:

· Limited buffering, module-based rate control minimizes on-chip memory for buffering and transmission bandwidth, and produces high-quality images.

· MoTIon JPEG for video rate control maximizes the quality of video for MoTIon JPEG data streams while using hardware resources more efficiently.

"Image compression simply means" JPEG "for the layman, but this is far from a" one-size-fits-all "technology". Nikos Zervas, vice president of marketing at CAST, said: "The choice of specific compression algorithms and their internal processing options can make a huge difference in quality, bandwidth, memory requirements, performance, and energy consumption. We can help customers become familiar with their specific systems , We are very proud of its decision and configuration of the best encoder. "

The JPEG encoder IP core now runs on the latest Altera® and Xilinx® FPGA, up to 400Msamples / s. This means that a single encoder IP core can process 1080p @ 60fps video on low-cost Altera Cyclone-V and Xilinx ArTIx ™ -7 devices, or on higher-end devices such as Altera StraTIx® V and Xilinx Virtex ®-7 FPGAs process 4k @ 30fps digital movies. At the same time, the IP core has also been tested with the new Xilinx Vivado ™ tool set, which has better efficiency.

CAST provides and supports the most extensive and deepest image compression IP core settings and effective subsystems, including JPEG, Scalado Speedtags JPEG, 12 / 8-bit Extended JPEG, Lossless LJPEG and JPEG-LS, and JPEG 2000. CAST video compression IP core includes multiple H.264 configuration files, MPEG2 and DV. The JPEG and H.264 IP cores come from technology partner Alma Technology Co., Ltd.

Indoor Fixed Advertising Led Screen

Indoor fixed advertising LED screens are large electronic display screens that are used for advertising purposes indoors. These screens are typically installed in high-traffic areas such as shopping malls, airports, train stations, and other public spaces.

Hot-selling series are p2/p2.5/p4/p5 led display video wall.
