— There has been an increase in the demand for a high-quality video codec that supports 4K (3,840×2,160) or more. JPEG2000 is an important technique for data compression, which has been successfully used in digital cinema and medical application. To process the high workload of JPEG2000 coding for large-scale video data, hybrid CPU/GPU platform is used to obtain high computing power. This paper describes the implementation of the JPEG2000 compression standard in multi-GPU platforms. Specifically, we propose the scalable cluster architecture of the JPEG2000 encoder to achieve scalability and high encoding speed. The proposed scheme can reduce the large encoding time and significantly improve the coding efficiency. The proposed scalable cluster system is very suitable for high-resolution video such as 4K or 8K containing large amounts of video data.
