Abstract
Abstract A multiple picture image manipulation system for receiving video information related to a plurality of pictures. A designation control designates the output priority order of the respective pictures. A priority coder detects picture information having the higher priority present for producing a control signal indicating this detected priority, and a selector controlled by this signal outputs information from the plurality of pictures so as to select from only a single picture designated with the higher priority present where picture overlap occurs to provide a multiple picture image in which one of said pictures masks another without overlap degradation when displayed. Additional facilities for cross-fading following a change in the picture priority may also be included which pictures can have an associated border if desired.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
127 words
A multiple picture image manipulation system comprising: a plurality of frame storage means for respectively receiving video information related to a plurality of pictures; means for designating the output priority order of the respective pictures from the respective frame storage means; means for detecting picture information having the highest priority present for producing a control signal indicating this detected priority; and selector means controlled by the signal from said detector means for selectively outputting information from the plurality of stored pictures held in said respective frame storage means so as to select from only a single picture designated with the highest priority present where picture overlap occurs to provide a multiple picture image in which one of the said pictures masks another without overlap degradation when displayed.
Claim 2
Dependent Claim
127 words
A multiple picture image manipulation system comprising: a plurality of frame storage means for respectively receiving video information related to a plurality of pictures; means for designating the output priority order of the respective pictures from the respective frame storage means; means for detecting picture information having the highest priority present for producing a control signal indicating this detected priority; and selector means controlled by the signal from said detector means for selectively outputting information from the plurality of stored pictures held in said respective frame storage means so as to select from only a single picture designated with the highest priority present where picture overlap occurs to provide a multiple picture image in which one of the said pictures masks another without overlap degradation when displayed.
Claim 3
Dependent Claim
36 words
A system according to claim 1, wherein change over means are provided for effecting a change over from one picture arrangement to another in a predetermined period as a result of re-designating the output priority therebetween.
Claim 4
Dependent Claim
38 words
A system according to claim 2, wherein the change over means is adapted to effect the change over gradually through several frame periods to provide a fade over facility whereby an overlying picture dissolves through an underlying picture.
Claim 5
Dependent Claim
35 words
A system according to claim 2, wherein the change over means comprises at least one multiplier and at least one adder for multiplying information from respective pictures by a predetermined coefficient and summing the result.
Claim 6
Dependent Claim
36 words
A system according to claim 4, wherein separator means are provided to separate the information present into chrominance and luminance components so as to allow separate summations of the chrominance and luminance information from respective pictures.
Claim 7
Dependent Claim
35 words
A system according to claim 5, wherein delay means are provided to receive identification data indicative of chrominance or luminance information to present this identification data concurrently with picture information received by the separator means.
Claim 8
Dependent Claim
41 words
A system according to claim 4, wherein the information comprises digital video data and converter means are provided following summation to convert the data into analogue form and wherein coding means are provided to encode the data into composite video form.
Claim 9
Dependent Claim
27 words
A system according to claim 1, wherein generating means are provided to generate border information to accompany video information on at least one of the manipulated pictures.
Claim 10
Independent Claim
106 words
A method of manipulating a multiple picture image comprising: receiving and storing respective frames of video information related to a plurality of pictures; designating the output priority order of the stored frames from the respective pictures; detecting picture information having the highest priority present for producing a control signal indicating this detected priority; and outputting information from the plurality of stored pictures in dependence on the control signal so as to select from only a single picture designated with the highest priority present where picture overlap occurs to provide a multiple picture image in which one of said pictures masks another without overlap degradation when displayed.
Claim 11
Independent Claim
106 words
A method of manipulating a multiple picture image comprising: receiving and storing respective frames of video information related to a plurality of pictures; designating the output priority order of the stored frames from the respective pictures; detecting picture information having the highest priority present for producing a control signal indicating this detected priority; and outputting information from the plurality of stored pictures in dependence on the control signal so as to select from only a single picture designated with the highest priority present where picture overlap occurs to provide a multiple picture image in which one of said pictures masks another without overlap degradation when displayed.
Claim 12
Dependent Claim
28 words
A method according to claim 9, including changing over from one picture arrangement to another in a predetermined period as a result of redesignating the output priority therebetween.
Claim 13
Dependent Claim
32 words
A method according to claim 10, wherein the change over is effected gradually over several frame periods to provide a fade over facility whereby an overlying picture dissolves through an underlying picture.
Claim 14
Dependent Claim
26 words
A method according to claim 10, wherein the change over is effected by multiplying information from respective pictures by a predetermined coefficient and summing the result.
Claim 15
Dependent Claim
29 words
A method according to claim 12, including separating the information present into chrominance and luminance components to allow separate summations of the chrominance and luminance information from respective pictures.
Claim 16
Dependent Claim
29 words
A method according to claim 13, including delaying identification data indicative of chrominance or luminance information to present this identification data concurrently with picture information at the separation step.
Claim 17
Dependent Claim
37 words
A method according to claim 12, wherein the information comprises digital video data and includes the steps of converting the data into analogue form following summation and encoding the data into composite form following the conversion step.
Claim 18
Dependent Claim
22 words
A method according to claim 9, wherein border information is generated to accompany the video information on at least one manipulated picture.
Claim 19
Dependent Claim
35 words
A system according to claim 1, wherein the detector means comprises a priority encoder for detecting the presence of picture information in the form of a keying signal provided from the respective frame store outputs.
