摘要： An information processing apparatus and method are disclosed by which data of the Open GOP structure can be edited while observing restrictions to a VBV Buffer. First and second sections including first and second editing points set to first and second compressed image data are decoded to produce first and second image data, respectively. The first and second image data are spliced together at the editing points and then re-encoded to produce re-encoded image data. Thereupon, the picture type of those pictures in the re-encoded image data which are positioned later in time in a display order than an I or P picture is not made different from that of pictures of the first and second compressed image data. Then, the first and second compressed image data and the re-encoded image data are switchably outputted to produce edited compressed image data.

摘要： The present invention can realize an image processing device and an image processing method that enable a simplified circuit configuration. An image encoding device (200) encodes an input image (91) in an ordinary process that is the same as main encoding on the basis of a predictive quantization parameter (QPd), while encoding the input image (91) in a simple manner (simplified process) on the basis of the predictive quantization parameter (QPd) and quantization parameters (QP) approximate to the predictive quantization parameter (QPd). The image encoding device (200) calculates a code quantity ratio R_reduction between a high-precision generated code quantity obtained through an ordinary process based on the predictive quantization parameter (QPd) and a generated code quantity obtained through a simplified process based on the predictive quantization parameter (QPd). The image encoding device (200) calculates high-precision generated code quantities based on the quantization parameters (QP) approximate to the predictive quantization parameter (QPd) on the basis of the code quantity ratio R_reduction and generated code quantities obtained through a simplified process based on the quantization parameters (QP) approximate to the predictive quantization parameter (QPd).
