Abstract
Abstract Method of integrating 30 or 60 frame/s format material and 60 field/s 2:1 interlace scan format digital video signal to produce a 60 field/s 2:1 interlace scan format digital video signal by producing a progressive scan format digital video signal from the format material, converting the progressive scan format digital video signal to a 60 field/s 2:1 interlace scan format digital video signal and combining the converted signal with the 60 field/s interlace scan format digital video signal.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
100 words
A method of integrating input 30 frame/s format material and a 60 field/s 2:1 interlace scan format digital video signal to produce an output 60 field/s 2:1 interlace scan format digital video signal, comprising the steps of: (a) producing from the input 30 frame/s format material a 30 frame/s progressive scan format digital video signal; (b) converting the 30 frame/s progressive scan format digital signal to a 60 field/s 2:1 interlace scan format digital video signal; and (c) combining the converted signal with the input 60 field/s interlace scan format digital video signal to produce a combined digital video signal.
Claim 2
Independent Claim
100 words
A method of integrating input 30 frame/s format material and a 60 field/s 2:1 interlace scan format digital video signal to produce an output 60 field/s 2:1 interlace scan format digital video signal, comprising the steps of: (a) producing from the input 30 frame/s format material a 30 frame/s progressive scan format digital video signal; (b) converting the 30 frame/s progressive scan format digital signal to a 60 field/s 2:1 interlace scan format digital video signal; and (c) combining the converted signal with the input 60 field/s interlace scan format digital video signal to produce a combined digital video signal.
Claim 3
Dependent Claim
41 words
A method as claimed in claim 1, wherein, in conversion step `b`, at least some of the fields of the converted signal are produced using motion compensated interpolation between successive frames of the 30 frame/s progressive scan formal digital video signal.
Claim 4
Dependent Claim
32 words
A method as claimed in claim 1, wherein production step `a` comprises the step of scanning 30 frame/s format source material to produce the 30 frame/s progressive scan format digital video signal.
Claim 5
Dependent Claim
30 words
A method as claimed in claim 1, further comprising the step of converting the combined 60 field/s 2:1 interlace scan format digital video signal to 30 frame/s progressive scan format.
Claim 6
Dependent Claim
46 words
A method as claimed in claim 4, wherein, in the conversion to 30 frame/s progressive scan format, none of the frames of the converted signal are produced using motion compensated interpolation between successive fields of the combined 60 field/s 2:1 interlace scan format digital video signal.
Claim 7
Dependent Claim
60 words
A method as claimed in claim 4, further comprising the steps of: digital-to-analogue converting the 30 frame/s progressive scan format digital video signal to form a 30 frame/s progressive scan format analogue video signal; and supplying the analogue video signal to a photographic recorder to record the content of the analogue video signal on photographic film in 30 frame/s format.
Claim 8
Dependent Claim
30 words
A method as claimed in claim 1, further comprising the step of converting the combined 60 field/s 2:1 interlace scan format digital video signal to 24 frame/s progressive scan format.
Claim 9
Dependent Claim
48 words
A method as claimed in claim 7, wherein, in the conversion to 24 frame/s progressive scan format, at least some of the frames of the converted signal are produced using motion compensated interpolation between successive fields of the combined 60 field/s 2:1 interlace scan format digital video signal.
Claim 10
Dependent Claim
60 words
A method as claimed in claim 7, further comprising the steps of: digital-to-analogue converting the 24 frame/s progressive scan format digital video signal to form a 24 frame/s progressive scan format analogue video signal; and supplying the analogue video signal to a photographic recorder to record the content of the analogue video signal on photographic film in 24 frame/s format.
Claim 11
Dependent Claim

The method as claimed in claim 1, further comprising the step of converting the combined 60 field/s 2:1 interlace scan format digital video signal to NTSC format.
Claim 14
Dependent Claim
31 words
The method as claimed in claim 1, further comprising the step of converting the combined 60 fields/ 2:1 interlace scan format digital video signal to 50 frame/s 1250-lines progressive scan format.
Claim 15
Dependent Claim
27 words
The method as claimed in claim 13, further comprising the step of converting the 1250-lines progressive scan format signal to 50 field/s 625-lines 2:1 interlace scan format.
Claim 16
Dependent Claim
32 words
