Abstract
Abstract An apparatus and corresponding method for reducing and displaying N input video scenes within a larger, selected main video scene. A main picture signal is selected from the N input picture signals. The N input signals are then selected sequentially by a counter to be auxiliary picture signals that are stored in respective areas of a digital memory. By switching the output signal between the main picture scene signal and the auxiliary picture scene signals from memory, the auxiliary picture scenes may be displayed at predetermined locations within the main picture scene. Additionally, one of the N input video signals may be from video tape recorder having an input provided by any of the remaining N-1 input video signals. Proper recording by the video tape recorder may then be monitored as one of the N auxiliary picture scenes.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
136 words
A device for processing video signals representing picture scenes, comprising: a first signal selecting means for selecting one of N input video signals (N being an integer greater than 1) as a main picture scene signal; a first conversion means for converting said N input video signals into N picture scene data groups, respectively; a storage means for storing said N picture scene data groups; a second conversion means for converting said stored N picture scene data groups into N reduced picture scene data groups; and a combining means for generating an auxiliary picture signal from said N reduced picture scene data groups and for combining said main picture scene signal with said auxiliary picture signal to create a second main picture scene signal representing a main picture scene having each of N reduced picture scenes.
Claim 2
Independent Claim
136 words
A device for processing video signals representing picture scenes, comprising: a first signal selecting means for selecting one of N input video signals (N being an integer greater than 1) as a main picture scene signal; a first conversion means for converting said N input video signals into N picture scene data groups, respectively; a storage means for storing said N picture scene data groups; a second conversion means for converting said stored N picture scene data groups into N reduced picture scene data groups; and a combining means for generating an auxiliary picture signal from said N reduced picture scene data groups and for combining said main picture scene signal with said auxiliary picture signal to create a second main picture scene signal representing a main picture scene having each of N reduced picture scenes.
Claim 3
Dependent Claim
38 words
A device for processing video signals according to claim 1, wherein said N reduced picture scenes represented by said N input video signals are arranged in a predetermined order in a predetermined area on said main picture scene.
Claim 4
Dependent Claim
29 words
A device for processing video signals according to claim 2, wherein said first signal selecting means includes a manually operated switch for selecting one of N input video signals.
Claim 5
Dependent Claim
36 words
A device for processing video signals according to claim 3, wherein said manually operated switch includes at least N operating keys and wherein the order of arrangement of said operating keys coincides with said predetermined order.
Claim 6
Dependent Claim
94 words
A device for processing video signals according to claim 2, wherein one of said N input video signals is a video recorder signal played back from a recording medium wherein said video recorder tunes a television signal on the air and outputs said television signal as one of said N video signals, and wherein said device further comprises a third signal selecting means for selecting one of said N input video signals other than said video recorder signal, and wherein the output of said third signal selecting means is recorded on said recording medium.
Claim 7
Dependent Claim
37 words
A device for processing video signals according to claim 5, wherein said third signal selecting means includes a second manually operated switch for selecting one of said N input video signals other than said video recorder signal.
Claim 8
Dependent Claim
40 words
A device for processing video signals of claim 6, wherein said second manually operated switch includes at least N-1 operating keys and wherein the order of arrangement of said operating keys of said second switch coincides with said predetermined order.
Claim 9
Independent Claim
133 words
A method for processing video signals representing picture scenes, comprising the steps of: selecting one of N input video signals (N being an integer greater than 1) as a main picture scene signal using a first signal selecting means; converting said N input video signals into N picture scene data groups, respectively using a first conversion means; storing said N picture scene data groups in a storage means; converting said stored N picture scene data groups into N reduced picture scene data groups using a second conversion means; generating an auxiliary picture signal from said N reduced picture scene data groups; and combining said main picture scene signal with said auxiliary picture signal to create a second main picture scene signal representing a main picture scene having each of N reduced picture scenes.
Claim 10
Independent Claim
133 words
A method for processing video signals representing picture scenes, comprising the steps of: selecting one of N input video signals (N being an integer greater than 1) as a main picture scene signal using a first signal selecting means; converting said N input video signals into N picture scene data groups, respectively using a first conversion means; storing said N picture scene data groups in a storage means; converting said stored N picture scene data groups into N reduced picture scene data groups using a second conversion means; generating an auxiliary picture signal from said N reduced picture scene data groups; and combining said main picture scene signal with said auxiliary picture signal to create a second main picture scene signal representing a main picture scene having each of N reduced picture scenes.
Claim 11
Dependent Claim
45 words
A method for processing video signals according to claim 8, wherein said step of combining includes a step of arranging said N reduced picture scenes represented by said N input video signals in a predetermined order in a predetermined area on said main picture scene.
