Abstract:

The framework of a digital cinema coding/decoding system is presented. The three key technologies of this system, colorimetry transformation, image compression and packaging for distribution are studied. Then it is implemented using computer software, with some additional optimization applied to accelerate the computation speed. Experimental results show that, this system completely conforms to the DCI specification, the compression efficiency is high, and the computation speed is fast, which are sufficient for further employment in research and applications.
