Abstract
Abstract This surveillance system employs a closed circuit television camera or cameras used in conjunction with an electronic cash register or registers employed at one or more point of sale stations. Combined images of transaction items viewed by a camera at a given station and transaction data (such as prices) rung up on the cash register at said station are presented on a television monitor. Signals for these combined images are also stored on video tape together with coded signals related to transaction data to achieve computerized editing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
190 words
A surveillance system for point of sale stations comprising: a television camera for developing frames of video signals representative of sales transactions performed by a human operator at a point of sale station where goods are moved by the operator across a sales counter and the prices are registered; means including at least one operator-controlled register for developing digital electronic signals representing data including price information entered by said operator at said point of sale station about said sales transactions concurrently with the development of said video frames; a video display device for visually displaying image frames of said transactions corresponding to and from associated frames of composite signals; and control means for generating a set of video character signals from said digital data signals of each of said sales transactions and for forming each of said frames of composite signals from one of said frames of video signals and a set of said character signals of the same transactions in a certain relation so that the associated character images are positioned on said display device in a certain location with relation to the associated image frames of said transaction.
Claim 2
Dependent Claim
190 words
A surveillance system for point of sale stations comprising: a television camera for developing frames of video signals representative of sales transactions performed by a human operator at a point of sale station where goods are moved by the operator across a sales counter and the prices are registered; means including at least one operator-controlled register for developing digital electronic signals representing data including price information entered by said operator at said point of sale station about said sales transactions concurrently with the development of said video frames; a video display device for visually displaying image frames of said transactions corresponding to and from associated frames of composite signals; and control means for generating a set of video character signals from said digital data signals of each of said sales transactions and for forming each of said frames of composite signals from one of said frames of video signals and a set of said character signals of the same transactions in a certain relation so that the associated character images are positioned on said display device in a certain location with relation to the associated image frames of said transaction.
Claim 3
Dependent Claim
29 words
A surveillance system as recited in claim 1, wherein said digital signal developing means includes means for developing digital signals of date and time data about said sales transactions.
Claim 4
Dependent Claim
28 words
A surveillance system as recited in claim 2, wherein said operator controlled register includes means for entering information about the types of goods moved across the sales counter.
Claim 5
Dependent Claim
46 words
A surveillance system as recited in claim 3, wherein said register are binary coded signals; and said character generating means includes means for converting said binary coded signals to signals in a multi-segment code, and means for forming multi-segment video signals from said multi-segment code signals.
Claim 6
Dependent Claim
34 words
A surveillance system as recited in claim 4, wherein said means for forming frames of composite signals includes means for varying the position of the character images within the format of said image frames.
Claim 7
Dependent Claim
101 words
A surveillance system as recited in claim 1, and at least one additional television camera to form a plurality of television cameras similar to said first-mentioned camera; at least one additional signal developing means including an operator controlled register to form a plurality of signal developing means similar to and including said first-mentioned signal developing means, each of said signal developing means being individually associated with a different one of said cameras, and coordinated switching means for interconnecting one of said cameras and the associated one of said signal developing means into an operative system in common with said control means.
Claim 8
Dependent Claim
92 words
A surveillance system as recited in claim 1, wherein said camera is movable to scan a plurality of said transaction stations; and further comprising at least one additional signal developing means including an operator-controlled register to form a plurality of similar signal developing means including said first-mentioned signal developing means, each being individually associated with one of said stations and individually operable with said control means; whereby the selection of a station to be monitored can be coordinated with the selection of the associated one of said signal developing means and register.
