Abstract

1.- The process by which information can be obtained from and by the broadcasting of radio and television signals electronically by including, through the digitalization of signals inaudible to humans, a code in the soundtrack of low or high frequency in the magnetic tapes in which communications are recorded to be transmitted by radio or television in such a way that the signals are picked up by a detector, which receives them and transmits them to a computer that uses subsonic or supersonic filters to identify the encoded signal and it processes the information included in it by virtue of the aforementioned digitalization and issues a report that contains data obtained thanks to the receipt of the digitized signal. 2.- Digitalisation generates codes that are inaudible to the human ear but gradable and reproducible in the soundtrack of the audiovisual and radio systems. 3.- The codes are produced using a digital tone generator with a system of numerical equivalences, these tones can be in the low band or in the high band. 4.- Once the tone is generated, a recording is made that can be copied to each copy of material that is intended to be broadcast on radio or television. These codes would be placed at the beginning of the transmission and at the end of it. 5.- The digitalized signal is transmitted by conventional means of radio or television. 6.- The transmitted signal is detected by a high-speed digital processor with several input ports per processing card. 7.- Each card works with a system of specific filters that detect each tone used by the tone generator. 8.- The combination of the signals produced by the channels of the filter produces a value that is associated to a database, identifying the message in question. 8.- Data entry to the card is done through the audio channel, so a device that is converting the electronic signals transmitted by radio or cable to sounds is required. 10.- The report consists of reporting, among other data, times of departure and reception, number of broadcasts and any other data related to that transmission by radio or television.

Description

INVENTION DENOMINATED "DIGITAL SYSTEM OF CODING OF AUDIO AND VIDEO SIGNALS".

INTRODUCTION Currently the corresponding information on the emission of signals by electronic means is not obtained accurately and quickly. The present invention consists of a system of objective and immediate nature of the broadcasting of signals by radio and television. It is a system that offers a new alternative to provide exhaustive, truthful and fast information on the radio and television broadcast of various types of signals within which advertisements are located.

DESCRIPTION The Digital Audio and Video Signal Coding System is an information system of an objective and immediate nature of the broadcasting of advertising spots on radio and television. The objective of this study is to provide exhaustive, truthful and rapid information on the broadcasting of advertisements via radio and television. The service consists of a method to identify and report the announcements transmitted by radio and television electronically. This system has three components: 1.- Inaudible message label. 2.- Detection network of inaudible labels. 3.- Automatic information reporting system. To this end, a sound labeling system has been developed for the announcements by means of a signal inaudible to humans. These signals and the corresponding reference catalog will be controlled by the service provider. These signals will be captured by a set of data collection stations that, temporally and spatially, will give testimony of the coverage of a certain message. Once the signal is captured, it will be transmitted to a computer that will record it and produce a transmission report.

The process, therefore, defines an identification code for each announcement that will be recorded in the soundtrack and that by means of subsonic filters will be identified by the computer that will record the start and end time of the announcement as well as the key location of the team. This information will be transmitted to a central computer that will prepare a part of the transmission that will be sent to the client and recorded in a database. The system has two fundamental elements: 1.- A system for generating codes inaudible by human ear but recordable and reproducible in the soundtrack of the audiovisual and radio systems and 2.- A system for detecting those signals and their subsequent electronic processing The codes are produced using a digital tone generator according to a system of numerical equivalences so that each tone corresponds to a numeric digit, these tones can be in the low band or in the high band according to the specific application that is doing. Once the tone is generated, a master recording is made that can then be copied to each copy of material that is intended to be transmitted by radio or television. These codes would be placed at the beginning of the transmission and at the end of it, giving a result similar to how bar codes work today. The coding system can be explained schematically through the following steps: 1.- Message 2.- Data bank 3.- Code 4.- Recording 5.- Code 6.- Message 7.- Transmission 8.- Coded message Codes The detection system is a high-speed digital process with several input ports for each processing card, • each of these cards works with a system of specific filters that detect each tone used by our tone generator, the combination of the signals produced by the filter channels produces a unique value that is associated with a database, identifying the message in question. The system can work individually or in a network. Data entry to the card is done through the audio channel, so a device that is converting the electronic signals transmitted by radio or cable to sounds is required. These can be momo station as it would be a radio or a television, or multistation as are the most modern equipment. The detection or reception system can be explained schematically through the following steps: 1.- Coded message. - Capture-Reproduction .- Audible Sign .- Computer-recognition system. - Database comparison. - Report emission. - Aggregate report: daily, weekly, monthly EU RECEPTION SYSTEM Report • Daily Added • Weekly MESSAGE • Monthly CODIFIED nm ??? my J -a? -uni-i [ji -r?
