Abstract
Abstract A video editing apparatus which can perform editing in units of frames with respect to video data encoded by GOPs using inter-frame correlation, in which video data recorded on an MO disc drive is decoded by an MPEG decoding unit and a predetermined frame of the decoded video data is substituted with other video data selected by a switch. The new video data including also the pictures of the frames before and after this is subjected to re-encoding at the MPEG encoding unit in a state where the original GOP frame structure before editing is maintained based on the signal indicating the punctuation of GOP input from the MPEG decoding unit and is recorded on the MO disk drive.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
155 words
A video editing apparatus for performing insertion editing on a compressed video signal that has been formed through inter-frame correlation of a plurality of continuous video frames and has been encoded in units of groups of pictures, comprising: decoding means for decoding the compressed video signal; switching means for selectively outputting a video signal supplied from the decoding means and a video signal input from the outside wherein when said switching means selects said outside video, signal said outside video signal is inserted into said video signal from the decoding means without regard to the inter-frame correlation of the compressed video signal; and encoding means for compressing and encoding a video signal supplied from the switching means again so that the frame structure becomes the same as the group of picture frame structure at the time of compressing and encoding the video signal before the switching processing based on said group of picture frame structure.
Claim 2
Dependent Claim
155 words
A video editing apparatus for performing insertion editing on a compressed video signal that has been formed through inter-frame correlation of a plurality of continuous video frames and has been encoded in units of groups of pictures, comprising: decoding means for decoding the compressed video signal; switching means for selectively outputting a video signal supplied from the decoding means and a video signal input from the outside wherein when said switching means selects said outside video, signal said outside video signal is inserted into said video signal from the decoding means without regard to the inter-frame correlation of the compressed video signal; and encoding means for compressing and encoding a video signal supplied from the switching means again so that the frame structure becomes the same as the group of picture frame structure at the time of compressing and encoding the video signal before the switching processing based on said group of picture frame structure.
Claim 3
Dependent Claim
57 words
A video editing apparatus as set forth in claim 1, wherein: the decoding means outputs a GOP head pulse showing the head frame of the GOP from the compressed and encoded video signal which is input and the encoding means compresses and encodes the supplied GOP head pulse and the video signal supplied from the switching means.
Claim 4
Dependent Claim
35 words
A video editing apparatus as set forth in claim 1, wherein: the encoding means compresses the video signal by the MPEG system and the decoding means decodes the compressed video signal by the MPEG system.
Claim 5
Dependent Claim
56 words
A video editing apparatus as set forth in claim 1, wherein said another video signal is recorded on the compressed and recorded video signal by recording an integer number of new GOPs onto said recording medium, such that said new GOPs overwrite said old GOPS, and such that there is no partial overwriting of old GOPs.
Claim 6
Dependent Claim
175 words
A video editing apparatus for performing insertion editing on a compressed video signal that has been formed through inter-frame correlation of a plurality of continuous video frames and has been encoded in units of groups of pictures, comprising: decoding means for decoding the compressed video signal; a control unit for outputting a selection control signal; switching means for selectively outputting a video signal supplied from the decoding means and a video signal input from the outside based on the selection control signal supplied from the control unit, wherein when said switching means selects said outside video signal, said outside video signal is inserted into said video signal from the decoding means without regard to the inter-frame correlation of the compressed video signal; and encoding means for compressing and encoding a video signal supplied from the switching means again so that the frame structure becomes the same as the group of picture frame structure at the time of compressing and encoding the video signal before the switching processing based on said group of picture frame structure.
Claim 7
Dependent Claim
175 words
A video editing apparatus for performing insertion editing on a compressed video signal that has been formed through inter-frame correlation of a plurality of continuous video frames and has been encoded in units of groups of pictures, comprising: decoding means for decoding the compressed video signal; a control unit for outputting a selection control signal; switching means for selectively outputting a video signal supplied from the decoding means and a video signal input from the outside based on the selection control signal supplied from the control unit, wherein when said switching means selects said outside video signal, said outside video signal is inserted into said video signal from the decoding means without regard to the inter-frame correlation of the compressed video signal; and encoding means for compressing and encoding a video signal supplied from the switching means again so that the frame structure becomes the same as the group of picture frame structure at the time of compressing and encoding the video signal before the switching processing based on said group of picture frame structure.
Claim 8
Dependent Claim
35 words
A video editing apparatus as set forth in claim 5, wherein the control unit is connected to an external interface and outputs the selection control signal based on an edit signal supplied via the interface.
Claim 9
Dependent Claim
54 words
A video editing apparatus as set forth in claim 5, wherein the control unit is connected to an external interface and outputs a recording control signal based on the edit signal supplied via the interface and a video signal compressed and coded based on the recording control signal is recorded on the recording medium.
Claim 10
Dependent Claim
58 words
A video editing apparatus as set forth in claim 5, wherein the decoding means detects the GOP head pulse indicating the head frame of the GOP from the compressed and encoded video signal which is input and the encoding means compresses and encodes the video signal supplied from the switching means in synchronization with the GOP head pulse.
Claim 11
Dependent Claim
37 words
An editing apparatus as vet forth in claim 5, wherein the encoding means compresses the input video signal by the MPEG system and the decoding means decodes the compressed and encoded video signal by the MPEG system.
Claim 12
Dependent Claim
56 words
A video editing apparatus as set forth in claim 5, wherein said another video signal is recorded on the compressed and recorded video signal by recording an integer number of new GOPs onto said recording medium, such that said new GOPs overwrite said old GOPs, and such that there is no partial overwriting of old GOPs.
