Abstract

Recently, high quality video services have become widely available. To transmit or store these HD video programs, compression is required and various lossy compression schemes have been developed. On the other hand, there are some applications which require lossless compression. However, most conventional lossless coding methods have high complexity and require a long processing time. In this paper, a parallel lossless compression algorithm with low complexity is proposed. The proposed compression algorithm reduced HD video sequences about by half. Furthermore, the processing time was significantly reduced when using a GPGPU. The algorithm can be implemented in real time for HD video sequences.
