Overview

The product J2K Video Compression System J2KVCS is being developed as a system for providing high speed on-board compression of captured color video of up to 80MBps data. The output compressed data can be compressed to the desired output data rate. The same is achieved by employing JPEG 2000 video compression engine. The output data can be transmitted through multiple interfaces like Ethernet, HDLC etc.

Specification

Input:

• Input data frequency – 40MHz (fixed)
• Data width – 16-bit; two channels of 8-bit each
• Input frame size – 1024 x 1024 pixels
• Input frame rate – 100 fps max; with reduced frame size
• Video input interface – Camera Link Interface
• Control input – Serial or any other desired interface

Power Supply:

• On board power supply – 28 V DC

Output:

• Output data rate limit – User desirable subject to system specs
• PSNR – 28 dB

Functionality

The system provides camera link interface for the camera input. The incoming frames are time stamped and sent to multiple video encoders (ADV 212) for compression. This compression is lossy in nature. The compressed data is captured back inside the FPGA, optionally encrypted and packetized. This packetized data can be PCM encoded for onward transmission.

Application

• Air borne target visualization
• Industrial process monitoring
• Surveillance

Deliverables

• Camera Link and Output Interface Board
• Video Compression Board
• Programming files for FPGA
• Windows based GUI for system validation
• Application software/firmware exe files
• User Guide (HW and SW)

Customization

Camera Link and Output Interface board can be modified to provide interface to client specific camera and client specific signal conversion/conditioning requirement for the compressed data output from the system.

Video Compression board can be configured for different compression ratio, synch pattern and output frame size selection.
