This document discusses using FPGAs for real-time video compression. It evaluates several video codecs for quality and complexity measures. It also analyzes the area and performance of two different FPGA implementations of its own video compression architecture called DPC. One implementation achieves a 4:1 compression ratio while the other achieves a 5.14:1 ratio. The document also discusses potential applications for endoscopy capsules.
