H.265 Encoder
Design IP
Overview

SmartDV’s H.265 (HEVC – High Efficiency Video Coding) Encoder IP core enables efficient, high-quality video compression for applications requiring low bandwidth and high-resolution output, such as broadcasting, video conferencing, surveillance, automotive, and cloud-based video services. It delivers real-time encoding of ultra-high-definition (UHD) content, significantly reducing storage and transmission demands while preserving visual fidelity.

The IP core supports Main, Main 10, and Main Still Picture profiles, offering full compliance with the H.265/HEVC standard. It features advanced rate control, low-latency encoding, support for multiple GOP structures, and compatibility with various chroma subsampling formats (4:2:0, 4:2:2, 4:4:4), making it well-suited for both professional and consumer-grade video applications.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance.
