Definitions
- the present invention relates to audimetry applied to television, that is to say to the identification in real time of the source of the images displayed on the screen of a television 5 or recorded and more precisely to the identification of that of the various image sources available to the user, such as, for example, the traditional terrestrial television network, a cable television network, a satellite television network, a video recorder, a camcorder, a video-disc, a database, etc., which is, at a given instant, displayed on said television or recorded.
- the traditional terrestrial television network a cable television network, a satellite television network, a video recorder, a camcorder, a video-disc, a database, etc.
- the present invention aims to propose a method making it possible to identify the image displayed on the receiver and its source, in a direct and simple manner by eliminating the need to equip the Scart boxes of the systems currently used in audimetry.
- the subject of the invention is a method of identifying image sources capable of being displayed selectively on a television receiver or recorded and their origin from the various sources available to the user, such as, in particular, the traditional hertzian television network, a cable television network, a satellite television network, a video recorder, a camcorder, a video- disk, a data bank, characterized in that it consists, at the level of reception at the user of the video signal coming from each of said available sources, at coding at least one line of the image in order to identify its source and its nature and, at the display or recording level, decoding the coded image line or lines in order to provide an appropriate audimetry system, in real time or deferred, in particular the identification of the image source available to the user displayed on the television receiver or recorded, at any time.
- the traditional hertzian television network such as, in particular, the traditional hertzian television network, a cable television network, a satellite television network, a video recorder, a camcorder, a video- disk,
- the coding of the image lines is carried out, in the known manner, on the so-called invisible lines, namely the lines numbered by convention 1 to 23.
- the coding can also make it possible to convey data other than identification the source, for example, when the source is a network of channels (traditional wireless network, cable network, satellite network), the identification of the number or name of the channel watched, or even data such as reading or recording when it is a VCR.
- FIG. 1 schematically illustrates the serving, for example at a user's home, a television apparatus by a plurality of video sources capable of being selectively connected to said apparatus;
- FIG. 2 represents the functional diagram of an embodiment of the device according to the invention for coding the signal of the image source at the level of its reception at the user;
- Figure 3 represents the functional diagram of the decoding device at the level of the television
- Figure 4 is a diagram of chaining of the sockets Perits of the various accessible image sources.
- FIG. 1 a television set has been shown on TV, installed for example in a private home equipped with an audimetry measurement device symbolized at A.
- audimetry measurement device symbolized at A.
- Such a device is well known and makes it possible to record data relating to the identification of the television channel watched by the user on his television during the day.
- VS1, VS2, VS3, VSn, etc. various video sources available to the user are symbolized, such as, for example, a traditional terrestrial television network, a cable television network, a satellite television network, a video recorder, camcorder, video-disc, data bank, etc ..., all connected to the TV receiver via the SCART socket of the latter or linked to the SCART socket of the latter.
- the installation is provided, on the one hand, at each image source available to the user, with a device for coding certain image lines and, on the other hand, at the receiver (and possibly the video recorder), a device for decoding the coded lines, connected to the audimetry device.
- FIG. 2 an embodiment of the device according to the invention is illustrated for coding the signal from the image source at the level of its reception at the user, the video signals coming from the Scart socket 1 where the various video sources VS1 to VSn are available to the user.
- the coding device C is constituted, in the illustrated embodiment, by a multiplexer 2 receiving by a first input the video signal coming from the Scart socket l. On the output of multiplexer 2 is available the video signal Vout intended for the TV receiver.
- a synchronization extractor 3 associated with a device 4 for searching image lines of the video signal makes it possible to select some of the image lines to code them using an encoder 5, the output of which is connected to a second input of the multiplexer 2 , the assembly being managed, in the known manner, by a control microprocessor symbolized in M.
- the device 3, 4 selects one, several or all of the so-called invisible image lines, the conventionally numbered lines 1 to 23 of the video frame, in order to insert therein determined binary states responsible for conveying information, namely and firstly the identification of the source of images available on take 1.
- the coding device C is produced in the form of a Scart box with male / female pins which will be plugged into the socket 1 and will therefore replace the latter.
- This decoding device D comprises a synchronization extractor 3 ', associated with a device 4' for searching image lines of the video signal Vout intended for the receiver
- the device D is advantageously produced in the form of a Scart box with male / female pins interposed between the Scart input of the TV receiver and the outlet delivering Vout.
- the multiplexer 2 of the coding device C makes it possible to exchange a line of the image by a line which contains information coded in binary form.
- the device 3, 4 makes it possible to count the lines of the video frame, to locate the zero line and to select the line or lines to be coded.
- the modulation of coding of the information which it is desired to introduce into the selected image lines can be of any type, for example DIDON.
- Video information may contain other data useful for audimetry, such as playback or recording, video overlay, simultaneous display of several channels, coded channel decryption, subtitling, etc.
- this video recorder must be equipped, like the TV television set, with a decoding device D.
- the device of the invention allows a simple and direct way to verify the integrity of the entire video installation of a user and its configuration point by point.
- the invention in the case of the use of Peritals sockets in chaining, as illustrated by FIG. 4, may, for all the boxes (designated C + D) associated with the sources VS1 to VSn, include the coding function and the decoding function, so as not to enter the source identification code
