    摘要: An apparatus for constant quality rate control in moving picture compression. First, a total activity measure for the current picture to be encoded in a set of consecutive pictures is calculated. Based on the total activity measure of the current picture and an activity-to-complexity ratio of a previously encoded picture of the same type in the set of consecutive pictures, a complexity measure of the current picture is estimated. Thus, an instantaneous complexity measure is updated using the complexity measure and then an instantaneous rate is calculated. A target bit budget is allocated to the current picture depending on the instantaneous rate, the complexity measure and the instantaneous complexity measure. After encoding, the activity-to-complexity ratio for the just encoded picture is computed based on the total activity measure, actual bits consumed by the picture and the average of actual quantization step sizes used to encode the picture.

    摘要: A method and apparatus for rate control in moving picture compression. Bit allocation with initial quantization step size estimation is used at picture level. With the relationship between pre-analyzed activity of current picture to be encoded and actual complexity of previously encoded picture of the same type, a target bit budget can be allocated to the current picture in accordance with the present invention. Once the target bit budget has been determined, an initial value for an average quantization step size is estimated on the basis of the target bit budget, along with the relationship between pre-analyzed activity of current picture and actual complexity of previously coded picture. Such an initial value of the average quantization step size is useful to achieve higher picture quality at a given bit allocation.

    摘要: A quantization matrix adjusting method for quality improvement by scaling down the default quantization matrix. The adjusting method comprises the steps of: updating a used bits BB_X and an average quantizer scale Avg_Q; allocating a bit budget BB_C for a current picture; calculating an estimated quantizer scale EstQ_C according to the used bits BB_X, the average quantizer scale Avg_Q and the bit budget BB_C deciding the operation mode, when the estimated quantizer scale EstQ_C is smaller than a threshold Th_Q, assigning the operation mode as an adjusting mode, otherwise remaining at normal mode; scaling down a default quantization matrix as a new quantization matrix when the operation mode is the adjusting mode; and coding the current picture using the new quantization matrix and default quantization matrix in the adjusting mode and normal mode, respectively.

    摘要: A video encoding method with support for editing when scene changed. The video encoding method reads and stores the pictures by the display order and detects whether the scene change occurred. The method encodes the pictures by the coding order when there are not scenes changed and encodes the pictures by a special coding process when there are scenes changed. Because the video encoding method encodes the pictures with considering the states of scenes changed and generates a new GOP when a scene change occurred, the video sequence can be cut into two parts by an image editing process without re-encoding. Therefore, the video can be edited without any loss and the editing performance of the editing process can be better.
