BA110 - JPEG 2000 encoder
Description
Capitalizing on its long-term experience with JPEG 2000 hardware coding, Barco Silex offers a large JPEG 2000 portfolio including this compact real-time hardware encoder engine that is optimized for Digital Cinema (DCI) and High-Definition (HD) video applications. The core architecture offers a flexible and high-speed solution to the challenges of digital cinema, broadcast and post-production applications. The BA110 is able to sustain the high encoding requirements of the large DCI frame formats, including 4096x2160 resolution and frame rates up to 48 frames per second.
The BA110 IP core is a JPEG 2000 hardware encoder dedicated to DCI (Digital Cinema Initiatives) and HD video applications. It performs the JPEG 2000 encoding of large un-tiled color frames with 4:4:4 or 4:2:2 sub-sampling. The BA110 generates compressed streams compliant with the ISO/IEC 15444-1 specification (JPEG 2000).
The IP core performs the following video compression operations of the normalized encoding process:
- Color transform (ICT/RCT)
- Discrete wavelet transform (DWT)
- Quantization
- Entropy encoding
- Rate allocation
The BA110 accepts pixels on its input interface with up to 12 bits per color components. It generates a j2c JPEG 2000 stream at its output interface.
The core is optimized for speed and is able to deal with the demanding DCI and HD processing requirements: it is able to provide a single-chip FPGA solution for all 2K@24 fps, 2K@48fps, 2K3D@24fps, 4K@24fps, 4K3D@24fps, 720p30/60, 1080i and 1080p30/60 resolutions.
The flexible FPGA architecture allows the user to build a secure encoder by integrating Barco Silex cryptography products (DCI AES).
