Video coding optimizations on embedded platform

We introduce a embedded platform-based video coding/streaming system based on MPEG-4 video compression standard. The system is implemented in software. Compared to a dedicated hardware implementation, software implementation is programmable thereby promising flexibility to incorporate new algorithms. Due to limited computational resources of PDA, the key modules of MPEG-4 codec are efficiently implemented and optimized, considering the characteristics of strongArm processor. The results indicate that the system proposed and developed has successfully reached the aim of real-time video coding/streaming.
