- FIG. 2 represents a remote control unit
- FIG. 3 represents a diagram of a circuit contained in this box
- FIG. 4 shows a flowchart of sequencing of operations to select the channel and switch on the device.
- the device of FIG. 1 comprises a television set 1 provided with:
- a tuner 2 receiving a signal for example from an antenna 3 and transposing the frequency of this signal to an intermediate frequency intended for a video intermediate frequency amplifier 4 and a sound intermediate frequency amplifier 5 which follow it, a demodulator 6, according to the sound intermediate frequency amplifier 4, which delivers the audio signals in baseband to an audio power amplifier 7, supplying a loudspeaker 8,
- a demodulator 9 following the video intermediate frequency amplifier 4, producing a baseband video signal for a video amplifier 10 delivering the ad-hoc signals to the electrodes of a picture tube 1 with cathode rays,
- a central unit 12 comprising a microprocessor 121 and a control element 122, for managing all of these functions.
- the control element can be integrated into the microprocessor.
- a second memory 132 of the memory 13 comprises a program for restarting the television in the standby state.
- the central unit is of course connected by a bus 14 to all the elements of the device which can be controlled by the control element: the tuner (choice of channels), the video and sound circuits (different level settings) , possibly scanning circuits not shown for the choice of different image formats.
- a command receiver 15 for receiving, in series, signals S of infrared light from a remote control unit 16, and transmitting them to the microprocessor 12.
- the remote control unit 16 in FIG. 2 has a key of standby 17, a pair of keys 18 making it possible to increase or decrease the value of a parameter, for example the power of the sound, a numeric keypad 19 allowing in particular the choice of a channel, keys 20 allowing by example of increasing or decreasing the number of the channel received. It is by means of the keys of the numeric keypad 19 that a channel identified by a two-digit number can be communicated to the television set 1, as will be seen below.
- FIG. 3 illustrates an example of a circuit usable for such a remote control unit.
- a battery 21 supplies a specialized microprocessor 22 and a light emitting diode 23, controlled by a transistor 24.
- the microprocessor contains a processor known per se, as well as necessary ROM and RAM memories, and includes a modulator which delivers pulses (intended for the diode 23) whose duration and number are programmable, and it has an output for controlling the transistor 24.
- a table 25 of ten positions is provided in the memory of the remote control, in which is recorded, in each position corresponding to a numerical value of the keys, a numerical value corresponding to a channel.
- the first nine channels of the channels usually referenced 1, 2, 3, ... are recorded on the ten positions, and it is possible to additionally register a channel at the position of the 0 key.
- the control signal Si (i corresponding to the number of control signals transmitted to the television) coming from the remote control intended for the television, whether it is in operating or standby state, comprises a control message of a type known per se. It includes a field containing a numerical value ranging from 0 to 9, containing the numerical value selected by the user by pressing the corresponding key. It can, moreover, start with a field containing a start bit "one", a field to describe the system that the command claims to reach (video recorder, television set, decoder, reader and / or recorder of discs, ).
- the present invention operates as follows:
- the television being in standby state, when the user presses a key on the remote control, the microprocessor 22 causes the emission, by the diode 23, of a message transmitting the digital value programmed associated with the position of the selected key.
- the television receives the infrared signal from the remote control, which transmits it to the microprocessor 12.
- the latter uses the standby software module stored in memory 13.
- the standby software essentially includes the following functions:
- connection message being made up subsequently of the decoded digital values
- algorithm for construction of the connection message implemented in memory 132 and executed by the microprocessor follows the following steps: - at time t1, after decoding of the first message decrypting a first digital value, the latter is stored in memory 131,
- connection message is decoded and if the stored digital value corresponds to a sequence of digits (coherence of the connection message), then the application software is launched starting all the elements to allow the effective connection on the desired channel and the operation of the television set, 2. If a second message is decoded during the delay ⁇ t deciphering a second value digital, then the construction of the connection message is done by replacing in memory 131 the first numerical value by a new number having as tens digit the first numerical value and as units digit the second numerical value.
- the decoding of several other messages succeeding each other with a delay of less than ⁇ t results in the deciphering of the digital values corresponding to these messages and the taking into account of the latter in each new memorized connection message (during the taking into account of a new numerical value, the numerical value corresponding formerly to the digit of the units is shifted on the left to correspond from now on to the digit of tens, the numerical value formerly corresponding to the digit of tens is shifted on the left to correspond to the digit of tens , etc).
- the flow diagram of FIG. 4 illustrates the sequence of operations carried out by the standby software module stored in memory 13.
- the module waits for the reception of a message from the remote control. He jumps to step 2 when he receives a message.
- the module tests whether it has already received a message, that is to say, if the memory 131 already contains a first message corresponding to the selection of a channel. If yes (step 3), the module shifts the messages: the message corresponding to the units becomes that corresponding to the tens. If there is already a message corresponding to the tens, it is overwritten by the new one. In step 4, whatever the previous events, the place of the units is free to receive the new message.
- step 5 the module starts a timer and watches for, during this, a new message is received. If yes, the module loops in step 3, to make room and then memorize this new message. If nc ⁇ . the user has not pressed a key on his remote control, he therefore validates the list of messages sent to the television receiver. In step 6, the module launches the television restart program displaying the channel whose number is the concatenation of the message of tens and units.
- channel corresponds to a specific frequency band in the case of the embodiment described, this may correspond to a track of the apparatus in the case of the disc player and / or recorder.
- the invention is not limited to the introduction of a two-digit channel number, but to one or more digits.
