Abstract
Abstract A surveillance system which can store and replay information which is not generated contemporaneously. In some point-of-sale systems, the behavioral events occur before the transaction data is generated. The present system asynchronously records the video signals corresponding to the behavioral events and the transaction data. Upon playback, the transaction data is matched up with the behavioral event being replayed from the video tape.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
225 words
A system for providing verifiable surveillance data by selectively positioning digital data on a video image without obscuring the video image, comprising: a) means for generating video signals of behavioral events corresponding to a desired transaction and marking the video signals with a sequence code from a sequence code source; b) means for storing the sequence coded video signals in a predetemined recording medium; c) means for generating digital signals representing data for said transaction, said digital signals including signals representing alphanumeric characters corresponding to the transaction, and marking the digital signal with a matching sequence code signal from an electronic system source common to the source in step a); d) means for storing the sequence coded digital signal in a recording medium different from said predetermined recording medium; e) means for retrieving selected stored video signals via its sequence code signal; f) means for retrieving selected stored digital signals via its sequence code signal; g) means for forming a composite vide-digital signal by selectively superimposing retrieved digital signals on the corresponding retrieved video signals of step e) wherein the digital signals overlie the corresponding behavioral event so as not to obscure the video signal; h) means for verifying that the video and digital signals have not been altered or otherwise tampered with; and i) means for displaying the composite video signal on a monitor.
Claim 2
Independent Claim
225 words
A system for providing verifiable surveillance data by selectively positioning digital data on a video image without obscuring the video image, comprising: a) means for generating video signals of behavioral events corresponding to a desired transaction and marking the video signals with a sequence code from a sequence code source; b) means for storing the sequence coded video signals in a predetemined recording medium; c) means for generating digital signals representing data for said transaction, said digital signals including signals representing alphanumeric characters corresponding to the transaction, and marking the digital signal with a matching sequence code signal from an electronic system source common to the source in step a); d) means for storing the sequence coded digital signal in a recording medium different from said predetermined recording medium; e) means for retrieving selected stored video signals via its sequence code signal; f) means for retrieving selected stored digital signals via its sequence code signal; g) means for forming a composite vide-digital signal by selectively superimposing retrieved digital signals on the corresponding retrieved video signals of step e) wherein the digital signals overlie the corresponding behavioral event so as not to obscure the video signal; h) means for verifying that the video and digital signals have not been altered or otherwise tampered with; and i) means for displaying the composite video signal on a monitor.
Claim 3
Dependent Claim
21 words
A system in accordance with claim 1 wherein the sequence code signals are independently generated signals synchronized from a common source.
Claim 4
Dependent Claim
30 words
A system in accordance with claim 1 wherein said sequence code is encypted and imposed on the video and digital signals to provide tamper-proof verification of the composite video-digital signals.
Claim 5
Dependent Claim
16 words
A system as claimed in claim 3 wherein the tamper proof verification means comprises a checksum.
Claim 6
Independent Claim
235 words
A system for processing related asynchronously recorded video and digital data to produce a composite video wherein the related video and digital data are combined in a manner to provide verifiable surveillance, comprising: a) means for generating video signals of behavioral events corresponding to a desired transaction and marking the video signals with a sequence code from a sequence code source; b) means storing the sequence coded video signals in a predetermined recording medium; c) means for generating digital signals representing data for said transaction, said digital signals including signals representing alphanumeric characters corresponding to the transaction, and marking the digital signal with a matching sequence code signal from an electronic system source common to the source in step a); d) means for storing the sequence coded digital signal in a recording medium different from said predetermined storage medium; e) means for retrieving selected stored video signals via its sequence code signal; f) mans for retrieving selected stored digital signals via its sequence code signal; g) means for forming a composite video-digital signal by selectively superimposing retrieved digital signals on the corresponding retrieved video signals of step e) where the digital signals overlie the corresponding behavioral event so as not to obscure the video signal; h) means for verifying that the video and digital signals have not been altered or otherwise tampered with; and i) means for displaying the composite video signal on a monitor.
Claim 7
