Low-delay video coding is a key technology for video conferencing as well as upcoming remote-monitoring and automotive video applications like rear-view cameras or night vision systems. As the ongoing progress in programmable DSP and ASIC technology allows cost effective and flexible implementations of the necessary hardware, compressed video transmission systems over multimedia busses will soon replace the current uncompressed systems even in latency critical applications. In this paper, fundamentals and theoretic limits of low-delay video coding are discussed with respect to architectural consequences of real-time implementations. A general latency analysis for a compressed video transmission systems is presented considering algorithmic, architectural and transmission related delays
