摘要： A data reading method for motion estimation in a video processing chipset is provided. The video processing chipset is coupled to an external memory device, wherein a first frame is stored in the external memory device. In the data reading method, a second frame is first divided into M×N sub frame sets, wherein each of the sub frame sets includes O×P sub frames. Then, each of the sub frame sets is selected in a calculation sequence, wherein the selected sub frame set is stored into an internal memory. Next, a predicted search path of each sub frame in the selected sub frame set is calculated. Thereafter, a predicted reading range is determined, wherein the predicted reading range includes the predicted search paths of the sub frames. Finally, a comparison data is read from the first frame according to the predicted reading range.

摘要： A method of an efficient adaptive mode selection for H.264/AVC-coded video delivery in burst-packet-loss networks to generate the image data of the missing macroblocks in the decoded current frame by using the information related to the spatial redundancy in the same frame and the temporal redundancy in the inter frames is disclosed. The method first employs the Intra High-Speed Spatial Error Concealment (SEC) method for the initial frame. For the succeeding inter frames, the Temporal Error Concealment (TEC) method is used when the Adjacent External Boundary Matching Error (AEBME) of the surrounding macroblocks is not more than the dynamic threshold (DTα). The Intra High-Speed SEC is used when AEBME is more than (DTα) and the surrounding macroblocks are all coded intra-method, otherwise the task proceeds by employing Normal SEC.

摘要： A method of fast motion estimation in VLSI architecture with low-power and high-throughput for multimedia System-on-Chip design is disclosed. The method uses the data prediction and data reuse technique to find out the best matching block within the search range of the reference frame for the target block in the current frame in order to obtain the respective motion vector. The external memory bandwidth and the internal memory size in the video coding system are significantly reduced so as to speed up the process of motion estimation and most of the power consumption for the motion estimation process is further saved in the embedded video coding systems.
