In this paper, a new early detection algorithm for all-zero DCT blocks in H.264 video encoding is proposed. We have analyzed the properties of the DCT and quantization in H.264. These analyses show that a great reduction in the number of calculations can be achieved by investigating the individual conditions for the frequency components of (1,1), (1,3),(More)
In this paper, we propose an improved coeff_token variable-length decoding (VLD) method in the CAVLC decoder. The number of memory accesses is one of the significant issues in the applications such as DMB and videophone services, where the low-power consumption and high-speed operation are required. In order to cut down the heavy memory accesses, a new fast(More)
