CAST H264-E Encoder H.264 IP Core for HD Video Compression

CAST introduced the H.264 encoder core. The CAST H264-E Encoder Core is ideal for applications that require the transmission of the highest quality video over low bit-rate channels — including remote medical diagnostics, military targeting, satellite reconnaissance, and advanced surveillance systems. It supports screen sizes from handheld (CIF, 352 x 240 pixels) to full HD (1080p30, 1920 x 1080 at 30 frames per second). The H264-E core is available now in RTL source code for ASICs or optimized netlists for programmable devices.

The CAST H264-E requires fewer resources (such as processing time, chip area, and power consumption) than competing cores that support higher-level profiles. The core readily fits and performs well in FPGA devices as well as ASICs — including Altera’s Cyclone III devices and the rest of the company’s FPGA and HardCopy ASIC families, and the Xilinx Virtex-4 and Virtex-5 device families.
