VC-2 HQ具有超低延迟的视频编解码器IP。
高质量的VC-2 HQ编解码器是一款超低延迟轻量级视频压缩IP内核，非常适合超低延迟视频传输。 该算法的低复杂度也允许对视频流进行高成本效益的压缩。 VC-2高质量压缩算法是一种简单的基于小波的帧内编解码器。 该算法在SMPTE 2042标准VC-2视频压缩中进行了描述。
特色
- Very light codec - fits even the most cost-efficient FPGA's
- VC-2 HQ is defined in the standard SMPTE ST 2042-1:2017
- No need for external DDR
- Resolution scalability: decode a lower resolution version
- Slice-based processing for high flexibility/parallelization
- Region Of Interest/Activity Zone coding
- Reverse order decoding (from bottom to top)
- AV over IP SMPTE ST 2110 compliant with RTP payload format standardized in RFC 8450
- Zero latency: encoding-decoding latency of only 8 lines
- Supports the following video parameters and encoding modes
- Unrestricted resolution including SD, HD, 2K, 4K, 8K
- 4:4:4, 4:2:2 and 4:2:0 color subsampling
- Interlaced and progressive formats
- 2-pixel interleaved video interface for UHD
- From 8 up to 16 bits per pixel component (HDR Ready)
- Haar0 and Haar1 Discrete Wavelet Transform (DWT) with 1, 2 or 3 levels
- Asymmetric LeGall Discrete Wavelet Transform (DWT)
- Constant bit-rate encoding (CBR) with adjustable compression ratio
- Lossless and constant quality/variable bit-rate encoding (VBR)
- Capped VBR encoding with maximum slice size
- Intellectual Property & Licensing
- VC-2 and its parent, the Dirac codec, are not covered by any granted patents and hence can be used royalty-free. BBC has provided assurances that they will ensure no patents encumber use of the codec and have let relevant patent applications expire allowing for free and fair use of the codec.
- Viper – Custom OEM board for 4K HDMI AV over IP
- Silex Insight has designed and developed fully integrated boards that is perfect suited for VC-2 HQ codec and ultra-low latency audio/video over IP. The transmit and receive boards are production-ready and reduce the development cost of the system. Viper features high resolutions up to 4K/UHD over 1Gb, 2.5Gb, or 10Gb Ethernet cable. The HDMI video is transported over Ethernet after compression with the VC-2 HQ (or JPEG 2000 or another codec) video compression.
