A flexible, line-based JPEG 2000 decoder for digital cinema

The image compression standard JPEG 2000 proposes a large set of features, useful for today's multimedia applications. Unfortunately, its complexity is greater than older standards. Real-time applications such as digital cinema requires a specific hardware implementation. In this paper, a decoding scheme is proposed with two main characteristics. Firstly, the complete scheme takes place in an FPGA without accessing any external memory, allowing integration in a secured system. Secondly, a customizable level of parallelization allows to satisfy a broad range of constraints, depending on the signal resolution.
