High-efficiency LCEVC video decoder IP supports 8K
VeriSilicon has launched the VC9000D_LCEVC, a next-generation Low Complexity Enhancement Video Coding (LCEVC) video decoding IP that is designed for high-performance and energy-efficient video processing.
The LCEVC IP works alongside the VC9000D base video decoder from Verisilicon to provide up to 8K Ultra HD decoding, making it ideal for advanced multimedia applications such as smart TVs, set-top boxes (STBs), and mobile devices. Its high-performance hardware architecture and complete subsystem ensure superior video quality with minimal load on the host CPU.
The latest standard from MPEG and ISO, LCEVC, or MPEG-5 Part 2, specifies an enhancement layer that is combined with a base video encoded with a separate codec to produce an enhanced video stream. The enhancement stream provides new features, such as extending the compression capability of the base codec, lowering encoding and decoding complexity, and providing a platform for additional future enhancements.
The VC9000D_LCEVC decoder fully complies with ISO/IEC 23094-2 (LCEVC) Main Profile, supporting up to Level 4.1. It processes 8/10-bit depth data, accommodates resolutions up to 8192×8192, and employs a frame-by-frame decoding architecture. In addition, it incorporates robust error detection to ensure reliable video playback.
With its high-performance hardware architecture and complete subsystem, VC9000D_LCEVC delivers superior video quality with minimal load on the host CPU. Its integrated Temporal Reference Frame Compression (TRFC) technology significantly reduces system bandwidth usage, while multi-level hierarchical clock gating minimises dynamic power consumption. It also integrates a post-processor for flexible output format conversion.
Delivered as a technology-independent, fully synthesisable Register Transfer Level (RTL) package, the VC9000D_LCEVC IP supports various process nodes and standard cell libraries, ensuring smooth integration into diverse System-on-Chip (SoC) designs.
“With the rapid growth of 8K content, AI-driven video applications, and the increasing demand for high-quality streaming and immersive experiences, the need for efficient, scalable video solutions is more critical than ever,” said Weijin Dai, Chief Strategy Officer, Executive Vice President, and General Manager of the IP Division at VeriSilicon. “By enabling seamless integration of LCEVC enhancement decoding into SoCs alongside our VC9000D base decoder, we help customers reduce bitrate and optimise bandwidth and storage costs while providing a highly efficient path to support next-generation multimedia applications.”
