    摘要: Low complexity edge detection and DCT type selection method to improve the visual quality of H.264/AVC encoded video sequence is described. Encoding-generated information is reused to detect an edge macroblock. Variance and Mean Absolute Difference (MAD) of one macroblock shows a certain relationship that is able to be used to differentiate the edge macroblock and the non-edge macroblock. Also, the variance difference of neighbor macroblocks provides a hint for edge existence. Then, a block-based edge detection method uses this information. To determine the DCT type for each block, the detected edges are differentiated as visual obvious edge, texture-like edge, soft edge and strong edge. 8×8 DCT is used for texture-like edges and the 4×4 DCT is used for all the other edges. The result is an efficient and accurate edge detection and transform selection method.

    摘要: In one embodiment, a coding mode selection method is provided to improve the visual quality of an encoded video sequence. The coding mode is selected based on a human visual tolerance level. Picture data may be received for a video coding process. The picture data is then analyzed to determine human visual tolerance adjustment information. For example, parameters of a cost equation may be adjusted based on the human visual tolerance level, which may be a tolerance that is based on a distortion bound that the human visual system can tolerate. The picture data may be analyzed in places that are considered visually sensitive areas, such as trailing suspicious areas, stripping suspicious areas, picture boundary areas, and/or blocking suspicious areas. Depending on what kind of visually sensitive area is found in the picture data, a parameter in a cost equation may be adjusted based on different visual tolerance thresholds. The coding mode is then determined based on the cost.

    摘要: An apparatus and a method for detecting the sync signal of a data signal are disclosed. The apparatus includes a clamping unit, a subtraction unit and a detection unit. The clamping unit receives the data signal and varies the level of the data signal. The subtraction unit coupled to the clamping unit subtracts the level of the data signal from that of the output of the clamping unit and then outputs the subtracting result. The detection unit coupled to the subtraction unit detects the subtracting result from the subtraction unit and judges the sync signal in the data signal accordingly.

    摘要: In one embodiment, a 3:2 pull-down detection component of a video encoder uses motion vectors to determine whether a repeated field exists in a video sequence. The 3:2 pull-down detection component uses field motion vectors determined by a motion estimator and compares the field motion vectors to a threshold to determine whether a repeated field exists. If a repeated field exists, a video encoder can then eliminate the repeated field.
