Overview

SmartDV’s H.264 Decoder IP is a fully featured Advanced Video Coding decoder solution purpose-built for SoC designs requiring reliable, standards-compliant video decoding across consumer electronics, broadcast, security, and embedded video applications. Fully compliant with ITU-T H.264 | ISO/IEC 14496-10 (MPEG-4 Part 10 AVC), it delivers complete H.264/AVC decoder functionality supporting video resolutions up to 3840×2160 at 60 fps, giving SoC teams a production-ready decoder for the most widely deployed video compression format used across streaming, broadcast, and storage applications.

Designed to handle the full breadth of H.264 decoder requirements, the IP supports both inter-prediction and intra-prediction methods, profile levels up to 5.2, 8-bit sample precision, 4:2:0 chroma subsampling, and both Variable Bitrate (VBR) and Constant Bitrate (CBR) encoded streams. Its production-tested decode pipeline gives consumer electronics, broadcast, and embedded SoC teams a spec-complete H.264/AVC decoder implementation suited for the widest range of video playback and transcoding applications, from mobile devices through set-top boxes and digital signage.

Built for design flexibility and silicon efficiency, the IP core is fully synthesizable with a static synchronous, positive edge clocked, scan test ready architecture and a simple interface for easy connection to microprocessor and microcontroller devices, enabling fast integration and confident design bring-up across a wide range of process nodes and target applications.
