The MIDI command may comprise a signal received from the toy control device 130, may comprise a response to a MLDI command previously received by the computer radio interface 110 from the computer 100, or may comprise a general command. The command contained in the MIDI command or in the received signal is executed (step 450). Executing the command may comprise, in the case of a received signal, reporting the command to the computer 100, whereupon the computer 100 may typically carry out any appropriate action under program control as, for example, changing a screen display or taking any other appropriate action in response to the received command. In the case of a MLDI command received from the computer 100, executing the command may comprise transmitting the command to the toy control device 130. Executing a MIDI command may also comprise switching audio output of the computer control device 110 between the secondary audio interface 230 and the radio transceiver 260. Normally the secondary audio interface 230 is directly connected to the audio interface 220 preserving the connection between the computer sound board and the peripheral audio devices such as speakers, microphone and stereo system. Reference is now made to Figs. 9B - 9N, and additionally reference is made back to Figs. 8D - 8M, all of which, taken together, comprise a simplified flowchart illustration of a preferred implementation of the method of Fig. 9 A. The method of Figs. 9B - 9M, taken together with Figs. 8D - 8M, is self-explanatory. Reference is now additionally made to Figs. 10A - 10C, which are simplified pictorial illustrations of a signal transmitted between the computer radio interface 110 and the toy control device 130 of Fig. IA. Fig. 10A comprises a synchronization preamble. The duration T_SYNC of the synchronization preamble is preferably 500 millisecond, being preferably substantially equally divided into on and off components. Fig. 10B comprises a signal representing a bit with value 0, while Fig. IOC comprises a signal representing a bit with value 1. It is appreciated that Figs. 10B and IOC refer to the case where the apparatus of Fig. 5D is used. In the case of the apparatus of Fig. 5E, functionality corresponding to that depicted in Figs. 10B and IOC is provided within the apparatus of Fig. 5E. Preferably, each bit is assigned a predetermined duration T, which is the same for every bit. A frequency modulated carrier is transmitted, using the method of frequency modulation keying as is well known in the art. An "off signal (typically less than 0.7 Volts) presented at termination 5 of U2 in Fig. 5D causes a transmission at a frequency below the median channel frequency. An "on" signal (typically over 2.3 Volts) presented at pin 5 of U2 in Fig. 5D causes a transmission at a frequency above the median frequency. These signals are received by the corresponding receiver Ul. Output signal from pin 6 of Ul is fed to the comparator 280 of Figs. 4 and 6 that is operative to determine whether the received signal is "off' or "on", respectively. It is also possible to use the comparator that is contained within Ul by connecting pin 7 of Ul of Fig. 5D, through pin 6 of the connector JI of Fig. 5D, pin 6 of connector JI of Fig. 5N through the jumper to pin 12 ofUl of Fig. 5A. Preferably, receipt of an on signal or spike of duration less than 0.01 * T is ignored. Receipt of an on signal as shown in Fig. 10B, of duration between 0.01 * T and 0.40 * T is preferably taken to be a bit with value 0. Receipt of an on signal as shown in Fig. 10C, of duration greater than 0.40 * T is preferably taken to be a bit with value 1. Typically, T has a value of 1.0 millisecond. Furthermore, after receipt of an on signal, the duration of the subsequent off signal is measured. The sum of the durations of the on signal and the off signal must be between 0.90 T and 1.10 T for the bit to be considered valid. Otherwise, the bit is considered invalid and is ignored. Reference is now made to Fig. 11, which is a simplified flowchart illustration of a method for generating control instructions for the apparatus of Fig. IN The method of Fig. 11 preferably includes the following steps: A toy is selected (step 550). At least one command is selected, preferably from a plurality of commands associated with the selected toy (steps 560 - 580). Alternatively, a command may be entered by selecting, modifying, and creating a new binary command (step 585). Typically, selecting a command in steps 560 - 580 may include choosing a command and specifying one or more control parameters associated with the command. A control parameter may include, for example, a condition depending on a result of a previous command, the previous command being associated either with the selected toy or with another toy. A control parameter may also include an execution condition governing execution of a command such as, for example: a condition stating that a specified output is to occur based on a status of the toy, that is, if and only if a specified input is received; a condition stating that the command is to be performed at a specified time; a condition stating that performance of the command is to cease at a specified time; a condition comprising a command modifier modifying execution of the command, such as, for example, to terminate execution of the command in a case where execution of the command continues over a period of time; a condition dependent on the occurrence of a future event; or another condition. The command may comprise a command to cancel a previous command. The output of the method of Fig. 11 typically comprises one or more control instructions implementing the specified command, generated in step 590. Typically, the one or more control instructions are comprised in a command file. Typically, the command file is called from a driver program which typically determines which command is to be executed at a given point in time and then calls the command file associated with the given command. Preferably, a user of the method of Fig. 11 performs steps 550 and 560 using a computer having a graphical user interface. Reference is now made to Figs. 12A - 12C, which are pictorial illustrations of a preferred embodiment of a graphical user interface implementation of the method of Fig. 11. Fig. 12A comprises a toy selection area 600, comprising a plurality of toy selection icons 610, each depicting a toy. The user of the graphical user interface of Figs. 12A - 12C typically selects one of the toy selection icons 610, indicating that a command is to be specified for the selected toy. Fig. 12A also typically comprises action buttons 620, typically comprising one or more of the following: a button allowing the user, typically an expert user, to enter a direct binary command implementing an advanced or particularly complex command not otherwise available through the graphical user interface of Figs. 12A - 12C; a button allowing the user to install a new toy, thus adding a new toy selection icon 610; and a button allowing the user to exit the graphical user interface of Figs. 12A - 12C. Fig. 12B depicts a command generator screen typically displayed after the user has selected one of the toy selection icons 610 of Fig. 12 A. Fig. 12B comprises an animation area 630, preferably comprising a depiction of the selected toy selection icon 610, and a text area 635 comprising text describing the selected toy. Fig. 12B also comprises a plurality of command category buttons 640, each of which allow the user to select a category of commands such as, for example: output commands; input commands; audio in commands; audio out commands; and general commands. Fig. 12B also comprises a cancel button 645 to cancel command selection and return to the screen of Fig. 12 A. Fig. 12C comprises a command selection area 650, allowing the user to specify a specific command. A wide variety of commands may be specified, and the commands shown in Fig. 12C are shown by way of example only. Fig. 12C also comprises a file name area 655, in which the user may specify the name of the file which is to receive the generated control instructions. Fig. 12C also comprises a cancel button 645, similar to the cancel button 645 of Fig. 12B. Fig. 12C also comprises a make button 660. When the user actuates the make button 660, the control instruction generator of Fig. 11 generates control instructions implementing the chosen command for the chosen toy, and writes the control instructions to the specified file. Fig. 12C also comprises a parameter selection area 665, in which the user may specify a parameter associated with the chosen command. The above-described embodiment of Fig. IC includes a description of a preferred set of predefined messages including a category termed "General commands". Other General Commands are defined by the following description: MU TIPORT COMMANDS AVAILABILITY INTERROGATION COMMAND A computer transmits this command to verify that the radio channel is vacant. If another computer is already using this channel it will respond with the Availability Response Command. If no response is received within 250msec the channel is deemed vacant. P: Computer address 00-03 H A: unit address - 00-FF II AVAILABILITY RESPONSE COMMAND A computer transmits this command in response to an Availability Interrogation Command to announce that the radio channel is in use. P: Computer address 00-03 H C A: unit address - 00-FF II TOY AVAILABILITY COMMAND O 3 O A Toy transmits this command to declare its existence and receive in response a Channel Pair Selection Command designating the computer that will o control it and the radio channels to use. σ. P: Computer address 00-03 II A: unit address - 00-FF H n > CHANNEL PAIR SELECTION COMMAND A computer transmits this command in response to a Toy Availability Command to inform the toy the radio channels to be used. P: Computer address 00-03 H A: unit address - 00-FF H CHI : Toy transmit channel 0- F H CHI : Toy receive channel 0- F H - In Figs. 13 and 14 there are illustrated block diagrams of multiport multi-channel implementation of the computer radio interface 110 of Fig. IA. Fig. 13 illustrates the processing sub-unit of the computer interface that is implemented as an add-in board installed inside a PC. Fig. 14 is the RF transceiver which is a device external to the computer and connects to the processing subunit by means of a cable. In the present application of the RF unit there are 4 transceivers each capable of utilizing two radio channels simultaneously. Referring briefly to Fig. 3, it is appreciated that, optionally, both sound and control commands may be transmitted via the M DI connector 210 rather than transmitting sound commands via the analog connector 220. It is additionally appreciated that the functions of the interfaces 210 and 220 between the computer radio interface 110 and the sound card 190 may, alternatively, be implemented as connections between the computer radio interface 1 10 to the serial and/or parallel ports of the computer 100, as shown in Figs. 25 A - 25F. If it is desired to provide full duplex communication, each transceiver 260 which forms part of the computer radio interface 110 of Fig. 1 A preferably is operative to transmit on a first charmel pair and to receive on a different, second channel pair. The transceiver 260 (Fig. 4) which forms part of the toy control device 130 of Fig. IA preferably is operative to transmit on the second channel and to receive on the first channel. Any suitable technology may be employed to define at least two channel pairs such as narrow band technology or spread spectrum technologies such as frequency hopping technology or direct sequence technology, as illustrated in Figs. 15A - 15E, showing a Multi- Channel Computer Radio Interface, and in Figs. 24A - 24E showing a Multi-Channel Toy Control Device. Reference is now made to Fig. 16 which is a simplified flowchart illustration of a preferred method of operation of a computer radio interface (CRI) 110 operative to service an individual computer 100 of Fig. IA without interfering with other computers or being interfered with by the other computers, each of which is similarly serviced by a similar CRI. Typically, the method of Fig. 16 is implemented in software on the computer 100 of Fig. IA. The CRI includes a conventional radio transceiver (260 of Fig. 4) which may, for example, comprise an RY3 GB021 having 40 channels which are divided into 20 pairs of channels. Typically, 16 of the channel pairs are assigned to information communication and the remaining 4 channel pairs are designated as control channels. In the method of Fig. 16, one of the 4 control channel pairs is selected by the radio interface (step 810) as described in detail below in Fig. 17. The selected control channel pair i is monitored by a first transceiver (step 820) to detect the appearance of a new toy which is signaled by arrival of a toy availability command from the new toy (step 816). When the new toy is detected, an information communication channel pair is selected (step 830) from among the 16 such channel pairs provided over which game program information will be transmitted to the new toy. A preferred method for implementing step 830 is illustrated in self-explanatory flowchart Fig. 18A. The "Locate Computer" command in Fig. 18A (step 1004) is illustrated in the flowchart of Fig. 18B. The identity of the selected information communication channel pair, also termed herein a "channel pair selection command", is sent over the control channel pair to the new toy (step 840). A game program is then begun (step 850), using the selected information communication channel pair. The control channel pair is then free to receive and act upon a toy availability command received from another toy. Therefore, it is desirable to assign another transceiver to that control channel pair since the current transceiver is now being used to provide communication between the game and the toy. To assign a further transceiver to the now un-monitored control channel, the transceiver which was formerly monitoring that control channel is marked as busy in a transceiver availability table (step 852). The transceiver availability table is then scanned until an available transceiver, i.e. a transceiver which is not marked as busy, is identified (step 854). This transceiver is then assigned to the control channel i (step 858). Fig. 17 is a simplified flowchart illustration of a preferred method for implementing "select control channel pair" step 810 of Fig. 16. In Fig. 17, the four control channels are scanned. For each channel pair in which the noise level falls below a certain threshold (step 895), the computer sends an availability interrogation command (step 910) and waits for a predetermined time period, such as 250 ms, for a response (steps 930 and 940). If no other computer responds, i.e. sends back an "availability response command", then the channel pair is deemed vacant. If the channel pair is found to be occupied the next channel is scanned. If none of the four channel pairs are found to be vacant, a "no control charmel available" message is returned. Fig. 19 is a self-explanatory flowchart illustration of a preferred method of operation of the toy control device 130 which is useful in conjunction with the "multi-channel" embodiment of Figs. 16 - 18B. i = 1, ..., 4 is an index of the control channels of the system. The toy control device sends a "toy availability command" (step 1160) which is a message advertising the toy's availability, on each control channel i in turn (steps 1140, 1150, 1210), until a control channel is reached which is being monitored by a computer. This becomes apparent when the computer responds (step 1180) by transmitting a "channel pair selection command" which is a message designating the information channel pair over which the toy control device may communicate with the game running on the computer. At this point (step 1 190), the toy control device may begin receiving and executing game commands which the computer transmits over the information channel pair designated in the control channel i. According to a preferred embodiment of the present invention, a computer system is provided, in communication with a remote game server, as shown in Fig. 20. The remote game server 1250 is operative to serve to the computer 100 at least a portion of at least one toy- operating game, which operates one or more toys 1260. Optionally, an entire game may be downloaded from the remote game server 1250. However, alternatively, a new toy action script or new text files may be downloaded from the remote game server 1250 whereas the remaining components of a particular game may already be present in the memory of computer 100. Downloading from the remote game server 1250 to the computer 100 may take place either off-line, before the game begins, or on-line, in the course of the game. Alternatively, a first portion of the game may be received off-line whereas an additional portion of the game is received on-line. The communication between the remote game server 1250 and the computer 100 may be based on any suitable technology such as but not limited to ISDN; X.25; Frame-Relay; and Internet. An advantage of the embodiment of Fig. 20 is that a very simple computerized device may be provided locally, i.e. adjacent to the toy, because all "intelligence" may be provided from a remote source. In particular, the computerized device may be less sophisticated than a personal computer, may lack a display monitor of its own, and may, for example, comprise a network computer 1270. Fig. 21 is a simplified flowchart illustration of the operation of the computer 100 or of the network computer 1260 of Fig. 20, when operating in conjunction with the remote server 1250. Fig. 22 is a simplified flowchart illustration of the operation of the remote game server 1250 of Fig. 20. Fig. 23 is a semi-pictorial semi-block diagram illustration of a wireless computer controlled toy system including a toy 1500 having a toy control device 1504, a computer 1510 communicating with the toy control device 1504 by means of a computer- radio interface 1514 and a proximity detection subsystem operative to detect proximity between the toy and the computer. The proximity detection subsystem may for example include a pair of ultrasound transducers 1520 and 1530 associated with the toy and computer respectively. The toy's ultrasound transducer 1520 typically broadcasts ultrasonic signals which the computer's ultrasound transducer 1530 detects if the computer and toy are within ultrasonic communication range, e.g. are in the same room. Figs. 24 A - 24E, taken together, form a detailed electronic schematic diagram of a multi-channel implementation of the computer radio interface 1 10 of Fig. 3 which is similar to the detailed electronic schematic diagrams of Figs. 5 A - 5D except for being multi-channel, therefore capable of supporting full duplex applications, rather than single-channel. Figs. 25 A - 25F, taken together, form a detailed schematic illustration of a computer radio interface which connects to a serial port of a computer rather than to the sound board of the computer. Figs. 26A - 26D, taken together, form a detailed schematic illustration of a computer radio interface which connects to a parallel port of a computer rather than to the sound board of the computer. Figs. 27A - 27J are preferred self-explanatory flowchart illustrations of a preferred radio coding technique, based on the Manchester coding, which is an alternative to the radio coding technique described above with reference to Figs. 8E, 8G - 8M and 10A - C. Figs. 28A - 28K, taken together, form a detailed electronic schematic diagram of the multi-port multi-channel computer radio interface sub-unit of Fig. 13. Figs. 29A - 291, taken together, form a detailed electronic schematic diagram of the multi-port multi-channel computer radio interface sub-unit of Fig. 14. Fig. 30 illustrates a further embodiment of the present invention which includes a combination of a Computer Radio Interface (CRI) and a Toy Control Device (TCD), 1610. The combined unit 1610 controls a toy 1620 which is connected to the computer 100 by a device, such as a cable, and communicates with other toys, 120, by means such as radio communication, using the computer radio interface 110. The toy 1620 is operated in a similar manner as the toy device 120. Fig 31 illustrates a simplified block diagram of the combined unit 1610. Figs. 32A, 32B and 32C taken together form a simplified schematic diagram of the EP900 EPLD chip (U9) of Fig. 28H. The code to program the EPLD chip for this schematic diagram preferably uses the programming package "Max Plus II Ner. 6.2" available from Altera Corporation, 3525 Monroe Street, Santa Clara, CA. 5051, USA. Figs. 33 - 54, described hereinbelow, illustrate embodiments of the toy system of Figs. 1 - 32C in which a computer-controlled toy system controls toys by means of a television or radio. Fig. 33 is a semi-pictorial semi-block diagram illustration of a toy 2010 sensing audio information 2020 from a television 2030 viewed by a user, wherein one or more microphones 2034, typically mounted on the toy 2010, senses the audio information 2020 in acoustic form and transmits a digital representation 2040 of this information, wirelessly, to a computer 2050. The toy then receives from the computer 2050 commands 2060 which are responsive to the digital representation 2040 of the audio information 2020. Radio communication is provided between the computer 2050 and the toy 2010 via a computer radio interface 2110, which is a hardware unit associated with the computer 2050 and a toy control device 2130 typically residing within the toy 2010. A preferred embodiment of the computer radio interface 2110 and of the toy control device 2130 are described in detail hereinabove with reference to Figs. 1 - 32C. Fig. 34 is a semi-pictorial semi-block diagram illustration of a modification of the apparatus of Fig. 33 which is similar to the apparatus of Fig. 33 except that the toy 2010 senses audio information 2020 from a radio 2070 listened to by a user. The toy senses the audio information 2020 in acoustic form and transmits a digital representation 2040 of this information, wirelessly, to a computer 2050. The toy then receives from the computer 2050 commands 2060 which are responsive to the digital representation 2040 of the audio information 2020. Alternatively, the radio may comprise an audio cassette player. Fig. 35 is a semi-pictorial semi-block diagram illustration of a modification of the apparatus of Fig. 34 which is generally similar thereto except that the toy control device 2130 receives the audio information in electronic form rather than in acoustic form. The electronic audio information is received from a radio receiver 2200 integrally formed with the toy, preferably interiorly disposed therewithin. The toy, therefore, functions as a radio. The audio information in acoustic form, whose reference numeral is 2020, is provided to the user by means of a speaker 2210. Typically, the apparatus of Fig. 33 also includes a similar speaker to allow the computer to command the toy to emit vocalizations. As shown in Fig. 35, the radio receiver 2200 receives radio entertainment broadcast information, transmits this information wirelessly to the computer 2050 and receives from the computer commands 2060 responsive to the radio entertainment broadcast information. The apparatus of Fig. 35 is advantageous, relative to the apparatus of Fig. 34, in that the quality of reception is typically enhanced because the audio information transmitted by the toy does not include acoustic noise generated by noise in the toy's environment. Fig. 36 is a semi-pictorial semi-block diagram illustration of a modification of the apparatus of Fig. 35 which is generally similar to the apparatus of Fig. 35 except that the audio information is received from a radio receiver 2220 connected to the computer rather than from a radio receiver residing in the toy 2010. The apparatus of Fig. 36 is advantageous, relative to the apparatus of Figs. 34 and 35, in that the toy's batteries or other power supply last longer because the toy does not have to transmit the audio information. Fig. 37 is a modification of the apparatus of Fig. 33 which is generally similar to the apparatus of Fig. 33 except that the audio information is received electronically from a TN receiver 2230 connected to the computer rather than acoustically from a TN monitor. The apparatus of Fig. 37 is advantageous, relative to the apparatus of Fig. 33, in that the toy's batteries or other power supply last longer because the toy does not have to transmit the audio information. The apparatus of Fig. 37 is also advantageous, relative to the apparatus of Fig. 33, in that the quality of reception is typically enhanced because the audio information transmitted by the toy does not include acoustic noise generated by noise in the toy's environment. Fig. 38 is a semi-pictorial semi-block diagram illustration of toy apparatus functioning as a PDA (personal digital assistant). The apparatus of Fig. 38 includes a computer 2050 such as a PC personal computer associated with a conventional telephony card 2250 or modem such as Dialog's D41 card, with a telephone jack 2260 and optionally with a telephone instrument 2270 enabling conventional telephone communication not involving the toy 2010. The computer 2050 is in radio communication with a toy 2010 via a computer radio interface 2110 and a toy control device 2130. Fig. 39 A is a simplified flowchart illustration of a preferred mode of operation for the apparatus of Fig. 38 allowing a call to be placed. In normal operation, as shown in Fig. 39 A, a user's request to place a telephone call is heard by one or more microphones 2034 mounted on the toy 2010 and is wirelessly transmitted to the computer 2050. The computer 2050 identifies key words using conventional speaker-dependent or speaker-independent speech recognition software such as products available from the following sources: Stylus Innovation Inc., One Kendall Square, Building 300, Cambridge, MA 02139, USA; A & G Graphics Interface, USA, at telephone number (617) 492 0120, telefax (617) 427 3625; "Dragon Dictate for Windows", marketed by Dragon Systems Inc., 320 Nevada Street, MA, 02160, USA; and "SDK", commercially available from Lernout & Hausple Speech Products, Sint- Krispijnstaat 7, 8900 Leper, Belgium. The computer 2050 stores a list of telephone numbers each associated with a name or other label such as "daddy". When one of the names or labels in the computer's memory is recognized, together with a dial request (such as the word "call"), the computer is operative to retrieve the telephone number corresponding to the name or label. According to a preferred embodiment of the present invention, names in the computer's memory may be associated with more than one telephone number, each telephone number being associated with a time interval. For example, a parent's telephone number may be associated with her work number during office hours, and with her portable telephone number during her normal commuting hours. The retrieved telephone number is dialled. If the call is answered, a request for the target person is preferably played to the responding party. The call is connected to the toy's speaker and microphone which function as the mouthpiece and earpiece respectively of a telephone instrument. Preferably, the device is operative to disconnect the call automatically after a silence of a predetermined duration or if the responding party disconnects. Fig. 39B is a simplified flowchart illustration of a preferred mode of operation for the apparatus of Fig. 38 for handling an entering call. Upon receipt of an entering call by telephony card 2250, the computer 2050 answers and prompts the caller to enter a password. The correct password is stored in the memory of the computer. If the password entered is correct, the computer 2050 connects the call to the toy as above. Fig. 40 is a simplified diagram of the interface between computer radio interface 2110 and soundboard 2190. The apparatus of Fig. 40 is a modification of the apparatus of Fig. 35 in which the MIDI connectors are omitted, such that the apparatus of Fig. 40 is useful in conjunction with sound-boards or computers which lack MIDI connectors. Fig. 41 is a simplified block diagram of a preferred implementation of computer radio interface 2110. Fig. 41 is a modification of the apparatus of Fig. 36 in which the MIDI connectors are omitted, such that the apparatus of Fig. 41 is useful in conjunction with sound- boards or computers which lack MIDI connectors. Fig. 42 is a simplified flowchart illustration of a preferred method allowing one of the computer radio interface 2110 and the computer 2050 to receive commands over the audio channel, rather than over the MIDI channel, from the other one of the computer radio interface 2110 and the computer 2050. The method of Fig. 42 first detect whether arriving information is audio information and if so, detects whether the audio information is entertainment-type audio information or a command. This is preferably effected by detecting whether or not a command- characterizing preamble has been received. The command-characterizing preamble typically comprises SYNC followed by SQ signals as described in detail below with reference to Fig. 43. Fig. 43 is a diagram of analog and digital representations 2300 and 2310 respectively of the following signals: SYNC, SQ, zero-valued bit and one- valued bit. The frequencies and time durations of each of the above signals are as follows: SIGNAL FREQUENCY TIME DURATION SYNC 2KHz 0.5 msec SQ 500 Hz 2 msec zero l KHz 1 msec one 666 Hz 1.5 msec Fig. 44 is a semi-pictorial semi-block diagram illustration of a toy sensing audio information from a television viewed by a user, wherein the toy transmits this information wirelessly to a computer and receiving from the computer commands responsive to the audio information, and wherein the source of the audio-visual information provided by the television is a NCR 2320 rather than a conventional television broadcast as in Fig. 33. Fig. 45 is a semi-pictorial semi-block diagram illustration of a toy, a television monitor and a computer including a TN receiver or television board 2230 operative to receive audio-visual entertainment information from a NCR 2320 and to transmit to the toy 2010 computer commands responsive to the audio visual entertainment information. In Fig. 45, the audio entertainment information is received electronically from the VCR via the television board connected to the computer rather than acoustically from a TN monitor as in Fig. 44. The apparatus of Fig. 45 is advantageous, relative to the apparatus of Fig. 44, in that the toy's batteries or other power supply last longer because the toy does not have to transmit the audio component of the audio-visual entertainment information. The apparatus of Fig. 45 is also advantageous, relative to the apparatus of Fig. 44, in that the quality of reception is typically enhanced because the audio information transmitted by the toy does not include acoustic noise generated by noise in the toy's environment. Fig. 46 is a semi-pictorial semi-block diagram illustration of a toy 2010 connected by a wire 2330 to a computer 2050, and a conventional audio entertainment provision system 2340 providing audio entertainment information. The entertainment provision system 2340, in the illustrated embodiment comprises a television set 2030 associated with a NCR 2320. However, alternatively, the entertainment provision system may comprise any of the entertainment provision systems shown and described above with reference to Figs. 33 - 45 and the source of the audio entertainment information may be either a broadcast or a local repository such as a cassette. The audio entertainment information is presented to the user and is also used by the computer 2050 to operate the toy 2010 in coordination with the presentation of the audio entertainment information. Figs. 47A - 47E, taken together, form a detailed electronic schematic diagram of a preferred implementation of the apparatus of Fig. 41. Fig. 48 is a semi-pictorial semi-block diagram illustration of a controllable toy system comprising a controllable toy 2010 and a radio signal receiver 2220 operative to receive an audio entertainment signal and a corresponding toy control signal from a remote radio transmitter. Unlike the embodiment of Fig. 36, in which the radio broadcast may be a conventional broadcast including only an audio component, in the embodiment of Fig. 48, the radio broadcast includes not only an audio component but also a toy control component. Typically, the radio broadcast comprises a stereo broadcast having two channels of which a first predetermined channel carries a mono audio component and the other channel carries the toy control component. Fig. 49 is a semi-pictorial semi-block diagram illustration of a modification of Fig. 48 in which the radio signal receiver is integrally formed with the controllable toy. Fig. 50 is a simplified self-explanatory flowchart illustration of a preferred method by which the computer analyzes an audio entertainment signal so as to recognize therewithin predetermined audio entertainment elements and to command the toy 2010 to perform at least one action having a predetermined association with the recognized predetermined audio entertainment elements. Fig. 51 is a simplified flowchart illustration of a preferred method for performing the TN/radio program coordination step of the method of Fig. 50. In the method of Fig. 51, a program may either be activated by the system itself (typically if the program is discovered by the system in its entertainment program time table) or alternatively may be activated by the user and acted upon by the system if the system recognizes the program as an optional program to be cooperated with only if activated by the user. Fig. 52 is a simplified flowchart illustration of a preferred method for performing the conformance checking step of the method of Fig. 50 in order to synchronize the toy's activities with a broadcast program. Preferably, the toy operates in accordance with a predetermined sequence of activities associated with a "keyword list" typically determined by a game programmer and stored on CDROM. The advantage of providing a keyword list is that the system knows what keyword is next expected, thereby reducing synchronization errors. Typically, the system is constructed and operative such that if a keyword detected by the speech recognizer or audio analyzer is found not to be in conformance with the next keyword in the keyword list, the system considers that keyword to have been missed if the next two keywords in the list are recognized in sequence in the broadcast program and considers the n'th detected keyword to have been a "false alarm" if the listed keyword is found to conform to the (n+l)th detected keyword. Fig. 53 is a simplified flowchart illustration of a preferred method for performing the "command toy..." step of the method of Fig. 50 in which the toy is activated in synchronization with the broadcast program. Fig. 54 is a semi-pictorial semi-block diagram of a controllable toy system operative in conjunction with a household audio entertainment player receiving an audio entertainment signal from a remote radio transmitter, the system comprising a controllable toy and a radio signal receiver, integrally formed with the computer and communicating with the toy by means of a wire. The radio signal receiver is operative to receive a toy control signal from a remote radio transmitter which transmits a toy control signal and a corresponding audio entertainment signal. The radio signal receiver also commands the controllable toy to perform at least one action according to said toy control signal.
