Description: BACKGROUND OF THE INVENTION Field of the invention The invention relates to a television receiver, comprising circuits for receiving, processing and displaying television signals, a controller having user operable control switches to cause said circuits to perform standard operating functions, and an arrangement for locally generating commercial advertising. The invention relates also to a method of advertising on a such a television receiver. Description of the related art Various television networks broadcast televised entertainment to the consumer free of charge. This is made economically possible by the inclusion of paid advertisements with the televised entertainment. Depending on the popularity of the particular televised program, advertisers are charged varying fees for their advertisements. These fees are also dependent on the length of each advertisement, the frequency of occurrence and the number of days (weeks, months) over which the advertiser desires the advertisement to be broadcast. Quite understandably, this form of advertising is very costly; for example, a single minute of advertising during the Super Bowl may cost upwards of one million dollars. United States Patent US-A-4,751,578 discloses a television receiver for viewing locally stored programming information. The known receiver includes an arrangement comprising means for storing data representing said programming information, means for converting said stored data into local video signals for display, control means coupled to said storing means for applying stored data representing said programming information to said converting means, and switching means for switching said local video signals to the display of said television receiver. The locally stored video signal may also be a commercial message. In the known receiver, the generation and display of the local video signal is controlled by the viewer, by pressing a button specially intended for that purpose. European Patent Application EP-A-0 451 622 discloses a television receiver which displays a locally stored time planner. The locally stored video signal is displayed upon switching the receiver on and off. This ensures that the time planner is always brought to the user's attention, without bothering him while he is watching regular television programs. United Stated Patent US-A-4,344,090 discloses a television receiver having a demo mode in which the receiver displays a locally stored advertisement at regular time intervals. SUMMARY OF THE INVENTION It is an object of the present invention to provide a television receiver and a method by which commercial advertisements are delivered to the consumer in a manner which better suits an advertiser's wishes. In accordance with the invention, this is achieved by a television receiver which is characterized in that the control means includes sensing means for sensing the operation of at least the control switches for channel selection or audio volume control, and for effecting the display of said commercial video signal in response to said sensing operation of said control switches. With the invention is achieved that an advertiser may have his/her advertisements encoded and stored in a read-only memory by a television receiver manufacturer upon the payment of an advertising fee. This ROM is then installed into television receivers containing the arrangement of the invention. Thereafter, at various times during operation of the television receiver by the consumer, the advertiser's advertisement is displayed on the screen of the television receiver. The displaying of the advertisement is triggered by the operation of often-used control functions of the television receiver such as channel change and/or sound volume control. The advertisement may take the form of a static image which appears on the screen in the same manner as the known "on-screen" channel number displays, as a banner across the bottom of the screen, etc., or as an animated image in the above manner. In the event that multiple advertisements are stored in the ROM, the arrangement of the invention may then cycle through to the next one of these advertisements each time it is to display one. The invention also contemplates the ability to update the contents of the advertisement memory such that new advertisements may be stored at a later date. The data representing these new advertisements may be sent to the television receiver over telephone lines, cable television services, broadcast data services, etc. In order to ensure that the paid-for advertisements are indeed periodically shown on the television receiver, the arrangement may include circuitry which defeats the operation of the television receiver if the arrangement has been tampered with by the consumer or any other unauthorized service person. BRIEF DESCRIPTION OF THE DRAWINGS With the above and additional objects and advantages in mind as will hereinafter appear, the invention will be described with reference to the accompanying drawings, in which: Fig. 1 is a block diagram of an arrangement according to the invention; and Figs. 2A-2E are representative displays on the television receiver showing various ways in which the advertisements may be presented. DESCRIPTION OF THE PREFERRED EMBODIMENT Fig. 1 shows a block diagram of an embodiment of the invention in which the arrangement is incorporated within a standard television receiver. In particular, the television receiver includes conventional receiver circuits 10, including a tuner, an audio processing circuit and a video processing circuit. The convention receiver circuits 10 provide video signals (RGB in the case of color) which are applied to a picture tube (not shown) for display. In a first embodiment of the invention, the arrangement includes a read-only memory (ROM) 12 in which data representing the various advertisements are stored. This ROM 12 is connected by a data bus 14 to a micro-controller 16 which, in conjunction with a program stored in program memory 18 coupled thereto by the data bus 14, determines when and which one of the various advertisements are to be displayed. To this end, a graphics & memory controller 20 is coupled to the micro-controller micro-controller 16 and the ROM 12 for addressing the ROM 12 under control of the 16 and for generating the appropriate graphic images representative of the data being addressed in the ROM 12. The output from the graphics & memory controller 20 is applied to a pallet controller 22 (in the event of color) via the data bus 14 which generates the RGB video signals for the particular advertisement. The RGB outputs of the pallet controller 22 are applied to a first input set of a switch 24 which receives at a second input set the RGB video signals from the conventional receiver circuits 10. Under control of the micro-controller 16, this switch 24 then selectively applies the advertisement video signals to the picture tube for a predetermined period of time. In the above configuration, the micro-controller 16 causes the advertisements to be displayed at regular time intervals in sequence. To this end, the micro-controller 16 includes an internal clock/calendar. However, it may be alternatively desired that the advertisements be displayed whenever a control function of the television receiver is addressed. In a second embodiment of the invention, the television receiver includes a receiver controller 26 which incorporates at least the power-on switch, the channel-up and -down control and the volume control. When any of these control functions are utilized, the receiver controller 26, in addition to performing the desired function, sends a control signal to the micro-controller 16 indicating which of the control functions was operated. The micro-controller 16 then causes one of the advertisements to be displayed for a predetermined period of time. In a third embodiment of the invention, the ability to update the advertisements is provided. The arrangement includes a programmable read-only memory (PROM) 28 which is also coupled to the data bus 14. A graphics update interface 30 is also coupled to the data bus 14 for providing update data to be written into the PROM 28 under the control of micro-controller 16 and the receiver controller 26. The graphics update interface includes a data input 32 for receiving the data updates which may be provided through data port in the television receiver connected to telephone lines, cable television services or broadcast data services. In a fourth embodiment of the invention, the consumer may be given the added benefit of including with the advertisements, various consumer programmable information including birthday or anniversary announcements, holiday greetings, seasonal notices, etc. Random-access memory (RAM) 34 is shown connected to data bus 14 for storing this consumer programmable information. In response to on-screen instructions effected by the receiver controller 26 and the micro-controller 16, the consumer is instructed to enter the appropriate information through the receiver controller 26 for storage in the RAM 34. Thereafter, the micro-controller 16 causes this information to be displayed sequentially with the advertisements in the ROM 12 and/or the PROM 28. In order to ensure that the paid-for advertising is indeed displayed, the arrangement includes a protection circuit 36 for detecting whether the arrangement has been tampered with by the consumer or any unauthorized service person. In the event that the protection circuit 36 detects tampering, a signal is sent to the receiver controller 26 disabling the television receiver until an authorized service person resets the system. Finally the arrangement may include an auditing function to enable the logging into memory of the actual displaying of the advertisements. To this end, the micro-controller 16 applies this data to the RAM 34 which may at some later time be interrogated for its contents. It should be understood that the display of the advertisements may take any convenient form. In particular, for example, upon power-on, an advertisement may be displayed full screen for a predetermined period of time as shown in Fig. 2A. When a channel change function has been selected, the advertisement may appear as a small insert along with, if available, the on-screen channel display as shown in Fig. 2B. Alternatively, the advertisement may appear as a banner across the bottom or top of the display screen (see Figs. 2C and 2D). If the television has a PIP function, the advertisement may be displayed full screen while the picture being watched is displayed as the PIP (Fig. 2E).
