Editing apparatus and editing method

Abstract

The invention discloses an editing apparatus and a method thereof. The editing apparatus for video data creates a bridge file for connecting a first file and a second file to be edited based on designation of an IN point of the first file, an OUT point of the second file, and connection points of the both files, a frame preceding the connection point of the first file being made an OUT point and a frame following the connection point of the second file being made an IN point, and the bridge file connecting the OUT point and the IN point, records the bridge file into a recording medium recording the first and second files, and creates an editing result file having file system information indicating recording positions: from the IN point to the OUT point in the first file; from the IN pointto the OUT point in the second file; and of the bridge file, in the recording medium.

Description

Editing device and editing method technical field The present invention relates to an apparatus and method for editing video data with variable frame size, such as video data encoded in a long GOP (Group Of Picture) format. In addition, the present invention also relates to an apparatus and method for editing video data with a variable frame size and recording file system information of the editing result. Background technique In the field of digital television broadcasting, the long GOP format conforming to MPEG-2 is used as an encoding (compression) format of video data. In the long GOP format, it is well known that a GOP consists of an intra-coded I-frame, and a P-frame and a B-frame coded by inter-prediction from a previous or subsequent frame, respectively. The long GOP format has the advantage that a high compression rate can be achieved by increasing the number of frames in one GOP. However, at the same time, since pictures are reproduced in GOP units, if the edi...

Note that although there have been references disclosing an editing method in which only some frames within a GOP are replaced with other frames (for example, Japanese Unexamined Patent Application Publication No. 09-18830), there has been no disclosure for cutting Reference of Editing Method for Editing Video Data Encoded in Long GOP Format
