Method and apparatus for the automatic identification and verification of television broadcast programs
First Claim
1. A method for automatically identifying and verifying the proper airing of a television program which has an identification code recorded on a selected line of each frame of the program and which is transmitted as a composite signal from one or more sending stations at one or more times over one or more channels for reception in a receiving area, comprising the steps of:
- (a) storing reference signals in a first memory means, each of said reference signals containing information referenced to said identification code specifying a bought airing of the program identified thereby;
(b) receiving each of the composite signals of said channels;
(c) automatically scanning said channels to detect the presence of said identification code and of a proper audio and video portion of each received composite signal which includes said identification code;
(d) separating the detected identification code from each of said received composite signals;
(e) generating an electrical time signal;
(f) generating a channel identifying signal;
(g) forming with said time signal and said channel identifying signal a separate verification signal for each separated identification code, said verification signal including information specifying said separated identification code and the time and channel of receiving said program;
(h) storing each said verification signal in a second memory means to identify a verified airing of said program; and
(i) comparing verified airings information from said second memory means with bought airings information from said first memory means and making therefrom a list of the number of verified airings that were bought airings and the number of bought airings for which there is no verified airing.

Abstract
An improved method and apparatus for identifying and verifying the proper airing of television broadcast programs wherein from the television broadcast, it can be assured that the programs were televised and received properly and aired at the scheduled time. The invention utilizes prerecorded or live video programs in which imprinted on a preselected scanning line is a digital encoded identifying number. These video programs with digital encoding are then distributed to network and/or local broadcast stations to be televised with this identification. A plurality of selected aired television channels are then automatically simultaneously monitored at a typical reception site whereby the encoded broadcast is appraised as to the quality of its audio and video, identified and timed, and which information is then stored for a later comparison to that which was actually intended to be aired.

9. In a system for verifying the transmission of a program from one or more sending stations over a plurality of communication channels for reception within a reception area, said program including a composite electrical signal having a video information component and a scanning control component, said video component including a periodically recurring identification component encoded to identify the informational content of said video component, apparatus for verifying the transmission of the program by the sending stations, comprising:
-
(a) means for storing reference signals, each including information referenced to said identification component specifying a bought airing of said program; (b) signal receiving means for receiving the composite signals of said plurality of channels; (c) means for scanning said received composite signals for detecting reception of composite signals including said identification component; (d) means for separating the identification component from the detected composite signal; (e) means for generating an electrical time signal; (f) means for generating a channel identifying signal; (g) means for forming separate verification signals for each reception of said program by combining said separated identification component, said time signal and said channel identifying signal; (h) means for storing each said verification signal; (i) means for comparing verification information from said verification signal storing means to said reference signals; and (j) means for providing an indication upon correspondence between said verification information and said reference signals for verifying the transmission of said program by said sending stations.

10. A method for automatically identifying and verifying the proper airing of television programs each having a unique identification code on a selected line of each frame thereof which are transmitted as composite signals from one or more sending stations over a plurality of channels for reception in a receiving area comprising the steps of:
-
(a) receiving the composite signal transmitted on each of said channels; (b) scanning automatically over said channels to detect the presence of one of said identification codes; (c) separating the detected identification code from the received composite signal of each of said programs; (d) forming a separate verification signal for each separated identification code, said verification signals identifying the time and channel of reception of the composite signals of each of said programs; and (e) comparing said verification signals with prerecorded reference signals identifying bought airings of said programs to verify said airings.

11. A method for automatically identifying and verifying the proper airing of television programs having a video and audio information portion and a individual identification code recorded on a selected line of each frame of the video portion thereof, said identification code being unique for each program, which programs are transmitted from a plurality of sending stations as composite signals for reception in a receiving area, comprising the steps of:
-
(a) storing reference signals in a first memory means, said reference signals containing individual bought airings information for each of said programs referenced to the corresponding identification code; (b) receiving the composite signals transmitted on each of said channels; (c) detecting automatically the presence of the identification codes in programs received on each of said channels; (d) separating the detected identification codes from the composite signals of each of said programs; (e) sensing the whether a proper audio portion is present in said programs; (f) generating electrical time signals and channel identifying signals; (g) forming separate verification signals for each detected identification code indicating the airing of the corresponding program on one of said channels, each of said verification signals including said identification code and the time, channel and audio quality of said corresponding program; (h) storing said verification signals in a second memory means; and (i) comparing said verification signals from said second memory means with said reference signals from said first memory means.
