    • 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.

    • 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.

    • A method of temporal error concealment for generating the image data of the missing macro-blocks in the current frame by using the previous frame and the correct data of the current frame is disclosed. The method includes the steps: first using Optimal Regression Plane to estimate the space motion vectors for each block in the missing macro-blocks; selecting appropriate motion vectors from the estimated space motion vectors and the correct temporal motion vectors in the previous frame as the candidate motion vectors; dividing the missing macro-block into sub-blocks with optimal size; fine tuning the candidate motion vectors as the predicted motion vectors; and using the predicted motion vectors to generate the predicted image data for the missing macro-block and further concealing the effect of the missing macro-blocks upon the image quality of the current frame. The method reduces the computation time, speeds up the process, and improves the image quality.

    • A spatial error concealment (SEC) method for concealing a spatial image error of an encoded image frame caused by a damaged macroblock (MB) is provided. The SEC method selects a proper SEC algorithm by adaptively classifying a plurality of correct MBs adjacent to the damaged MB, so as to execute interpolation pixel compensation or matching block copying, thus obtaining image data of the damaged MB. In such a way, the damaged MB is processed to apply the least affection to the entire image frame. The SEC algorithm is selected from bilinear interpolation (BI) method, directional interpolation (DI) method, multi-directional interpolation (MDI) method, and best neighborhood matching (BNM) method. The SEC method further includes a fast determination calculation, which utilizes image directional data related to the damaged MB in coding data of the original frame to execute a direct SEC process, for saving time on determination calculation, thus accelerating the processing speed.
