Analysis: BDTI Certifies ARC's H.264 Performance
H.264 decoder solution performance is reported as the minimum clock rate required to decode BDTI's Primary Operating Point bitstream in real-time. The Primary Operating Point uses the following basic parameter settings: "D1" resolution (720 x 480 pixels), 30 frames per second, Baseline Profile, and a maximum bit rate of 1.5 Mbps. Two important factors that affect the minimum clock rate required for real-time operation are the number of output "delay buffers" used and the performance of external (main) memory. In recognition of these factors, BDTI has chosen to present the minimum clock rate required by the ARC Video Subsystem for real-time operation for a number of output delay buffer sizes and a range of external memory access times (see Figure 1).
