Definitions
- the present invention relates to a method as defined in the preamble of claim 1 for modifying the content of a television image.
- 01/58147 discloses a method for modifying the image of a visible object shot by a television camera.
- the object to be imaged is marked by means of a marking surface which can be identified on the basis of radiation differing from other radiation in the area to be imaged, the radiation of at least one of said marking surfaces differing from the environment in respect of a property other than the color of visible light.
- a marking surface which can be identified on the basis of radiation differing from other radiation in the area to be imaged, the radiation of at least one of said marking surfaces differing from the environment in respect of a property other than the color of visible light.
- at least one identifying detector separate from the detectors of the television camera is used, said detector imaging the object from substantially the same direction as the television camera is shooting.
- the relation between the image coordinate systems of the television camera and the identifying detector is determined and the areas visible in the television picture of the object are determined by the aid of the marking surfaces detected.
- the image signal for the television image areas corresponding to the object is modified in a predetermined manner and
- the object of the invention is to eliminate the above-mentioned drawbacks.
- a specific object of the invention is to disclose a new type of selection method that allows individual, even spectator-specific modification of television broadcasts.
- an event is imaged by at least one camera and the image signal produced by the camera is transmitted to spectators ' receivers to present the event .
- po- sition data for the television image area to be modified is transmitted, and said position data, together with the image information used in the modification and the information controlling the modification, is fed to a separate modification device.
- the spectators are grouped using certain criteria to form spectator groups so that the image signal can be modified in a manner selected separately for each group.
- the image signal can be transmitted and the event presented in a desired form appropriately modified for a spectator group meeting certain criteria.
- distinctive information regarding the area is also transmitted.
- information about the content of this area to be modified or other information relating to it is also received, on the basis of which it will be possible to know at what juncture the area in question is to be modified, i.e. replaced with other image data.
- image material it will be known what image material is to be used for the modification, i.e. what is to be shown instead of the original image .
- image signals about the same event are modified simultaneously, and the signals are transmitted and presented to different spectator groups.
- the image signal is modified e.g.
- the image signal can be modified in a manner consistent with the legislation, common good practice, religion and/or traditions prevailing in the region concerned.
- advertisements on these products can be replaced with other advertisements as appropriate.
- some ethical or religious groups do not approve of advertising of certain goods, so such advertisements can be replaced with acceptable ones.
- the image signal to be transmitted can also be modified specifically for each television company, for each Internet server, for each television receiver, or the image signal can even be modified in a spectator-specific manner.
- the image signal is preferably modified for a given homogeneous spectator group, which is formed on the basis of spectator interviews, inquiries, gallup polls and/or other information collected.
- suitable spectator groups or even individual spectators can supply basic information according to which the broadcasts are to be modified, taking the spectators' interests and negative associations into account.
- the substituting image information to be used in the modification can be supplied to the modification device over a television broadcasting network, over the Internet, over a wireless telephone network or over a wired telephone network.
- the image information may also be supplied together with the program being transmitted.
- a further possibility is to transmit and load the image information to the modification device beforehand. In this way, the actual transmission from the scene of the event to all receiving parties consists of an identical image signal, and the image signal is modified into the desired form e.g. specifically for each country by means of the modification devices.
- the television image contains changing, transient and moving visual ob- structions hiding the image area to be modified.
- an athletic performance, an athlete or a vehicle partially hides an advertisement in the background from view.
- a masking image is formed, from which a separate image signal is generated.
- the image in the background can be replaced and the athletic performance taking place in front of it can be shown unchanged.
- the method of the invention is preferably used in direct television broadcasts, in other words, the image signal is transmitted and presented on television as a direct telecast.
- recordings as post-telecasts, in which case the modifications can be made in connection with the broadcast or even earlier at a suitable stage.
- An- other possibility is to use the modified image signal in mobile telephones and/or on the Internet.
- the method of the invention has significant advantages.
- the method of the invention makes it possible to freely choose and modify advertisements in television broadcasts by taking aspects of the spectatorship into account. In this way, advertisers will avoid troublesome and annoying contacts with the public or, on the other hand, if such contacts are expressly sought, then that, too, will be easy to achieve via selective advertising according to the invention.
- illegal hidden advertising can be held in check by the method of the invention, because every advertisement visible e.g. at a given sports happening can, if desirable, be replaced with another, allowed advertisement or removed altogether by showing only a void surface of suitable color in its place.
- An event is imaged by a television camera 1 and simultaneously the image area is observed by means of auxiliary equipment 2 to identify the image portions to be modified.
- the auxiliary equipment may consist of e.g. beam splitters and infrared cameras.
- the generation of the information controlling the modification of the image takes place in the same way as the generation of the television signal.
- the television signal 4 is packed with the modification signal to be transmitted together, and received and decoded 5 at the receiving end, which may consist of a country-specific, regional or even receiver-specific reception system.
- the signal to be used for the modification can also be transmitted by a separate route and/or as a separate signal along with the television signal to the target.
- both the television image signal and the information needed for the modification i.e. information specifying the positions of the areas to be replaced in the broadcast.
- the control information also comprises data indicating when and what change is to be made in each specific area. In other words, for example in an ice hockey match, it is possible to show a different advertisement in a given advertising area during each period, and again different advertisements can be shown during the rest periods .
- the replacing content material 7 is transmit- ted e.g. beforehand to each receiver group.
- the areas to be replaced or modified may be different for different receiver groups.
- the same television image signal is transmitted to each receiver group, regardless of whether that group consists of an individual person or a large country.
- the image signal is modified into a desired form and after the modification the image signal 8 thus modified for a given spectator group is transmitted.
