Abstract

Abstract A video data editor edits video data which has been predictive-coded between pictures. An editing controller outputs number data for specifying video data to be read from a recording medium and editing point data indicative of editing points of the vide data to be read. The video data is read from the recording medium in accordance with the outputted number data. The read video data is decoded to obtain reproduced pictures. The reproduced pictures are coded to obtain re-coded video data. Before and after the editing points, original coded video data is switched to the re-coded video data on the basis of the editing point data. In stead of the editing point data, video processing control data indicative of types of video processing for editing can be used. With the video processing control data, when judged that the video processing is proceeding, original coded video data is switched to the re-coded video data, before, during and after the video processing.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 115 words
A video data editor for editing video data predictive-coded between pictures, comprising: editing control means for outputting number data for specifying video data to be read from a recording medium and editing point data indicative of editing points of the video data to be read; reproducing means for reading the video data from the recording medium in accordance with the outputted number data; decoding means for decoding the read video data to obtain reproduced pictures; coding means for coding the reproduced pictures to obtain re-coded video data; and switching means, before and after the editing points, for switching original coded video data to the re-coded video data on the basis of the editing point data.
Claim 2
Dependent Claim 38 words
The video data editor of claim 1, wherein said coding means codes video data, on the basis of the editing point data outputted by said editing control means, without using inter-picture prediction before and after the editing points.
Claim 3
Dependent Claim 142 words
A video data editor for editing video data predictive-coded between pictures, comprising: editing control means for outputting number data for specifying video data to be read from a recording medium, and video processing control data indicative of types of video processing for editing; reproducing means for reading the video data from the recording medium in accordance with the outputted number data; decoding means for decoding the read video data to obtain reproduced pictures; video processing means for video-processing the reproduced pictures in accordance with the video processing control data, to obtain processed pictures; coding means for coding the processed pictures to obtain re-coded video data; and switching means, in response to the video processing control data, for judging that the video processing is proceeding, to switch original coded video data to the re-coded video data, before, during and after the video processing.
