Abstract
H.264 technology is considered as the heart of the next-generation video codec standard. Europe and other countries have actually specified H.264 technology as the video codec standard for HD broadcasting. However, due to the complexity of algorithm, it is still a difficult job to implement HD-level H.264 decoders in real-time software. In this paper, I have restricted a part of the decoding process, in order to implement an H.264 software video decoder which guarantees a real-time operation, and suggest an H.264 decoder that adaptively selects the algorithm to minimize image degradation. Performance of the suggested H.264 decoder was compared and verified through a PC simulation. As a consequence, when the suggested decoder was used in an environment where real-time decoding was difficult, it has achieved the minimal image degradation as well as real-time decoding in most cases.
