Problems solved by technology

[0010] However, if see figure 1 The method described is used to perform editing and re-encoding, which causes the problem that a picture cannot be referenced at a junction point between a part where re-encoding is performed and another part where re-encoding is not performed

Embodiment Construction

[0095] In the following, embodiments of the present invention will be described with reference to the drawings.

[0096] Figure 4 is a block diagram showing the hardware configuration of an editing device to which the present invention is applied.

[0097] CPU (Central Processing Unit) 1 is connected to North Bridge 12, and controls processing such as read-out processing of data stored in HDD (Hard Disk Drive) 16, and generates and outputs data for controlling to be executed by another CPU 20. Edit processing commands. The North Bridge 12 is connected to a PCI (Peripheral Component Interconnect / Interface) bus 14, and under the control of the CPU 11, for example, receives data stored in the HDD 16 through the South Bridge 15. Memory 18 provides the received data. The north bridge 12 is also connected to the memory 13 , and supplies and transfers data necessary for the processing of the CPU 11 to and from the memory 13 .

[0098] The memory 13 stores data necessary for proc...

Abstract

The invention relates to an information processing apparatus and an information processing method, a recording medium and a program wherein an optimum generation code amount is allocated while obeying restrictions to a buffer to execute editing of a compressed image signal so that deterioration of the picture quality can be prevented. A re-encoding duration is an entire extended re-encoding interval, and a no editing re-encoding duration is a portion other than an editing duration while a no editing re-encoding GOP duration is a portion other than an editing GOP duration. To a picture within a range of an editing point within which the possibility that the degree of difficulty in encoding may become high due to an effect is high, a code generation amount is allocated from a picture in the no editing re-encoding GOP duration. Therefore, the picture within the range of the editing point can use an increased code generation amount. The invention can be applied to an editing apparatus.

Description

technical field [0001] The present invention relates to an information processing device, an information processing method, a recording medium and a program, in particular to an information processing device, an information processing method, a recording medium and a program suitable for use when video data is compressed and bidirectionally inter-frame predicted and edited. Background technique [0002] An image compression method represented by the MPEG (Moving Picture Coding Experts Group / Moving Picture Experts Group) method achieves high compression efficiency by compressing an encoded image signal using inter-frame prediction. However, when images are intended to be edited, since compressed image materials formed using inter-frame prediction cannot be joined together, at the same time, since they have a relationship of compressed signals by prediction between frames, they remain in the form of compressed image signals , therefore, systems configured to edit image materia...
