BACKGROUND OF THE INVENTION
1. Field of the Invention.
The present invention relates to a remote control for a television set which is of the type that has digit keys for the direct entry of a select channel but no channel "up" or "down" keys. Also, the software/programming of the remote control of the present invention be used in a remote control which has a channel "up" or "down" to "automate" the process of scanning channels thereby reducing the number of button/key presses required from the user.
2. Description of the related art.
Heretofore a variety of remote controls both dedicated and universal have been proposed for operating televisions, VCR and other consumer electronic equipment. Typically, such remote controls are provided with a keypad or keyboard with digit keys thereon and some with alphabet keys thereon.
In the United States most remote control devices also have channel "UP", channel "DOWN", volume "UP" and volume "DOWN" keys.
However in Europe and other countries around the world channel "UP" and channel "DOWN" keys often are not provided even though it is desirable to have this function. As will be described in greater detail hereinafter the remote control of the present invention has circuitry and executable programs which, upon detection of a special "SCAN" command such as by the depression of a certain key, e.g., a "SCAN" key, on the keypad automatically starts a step-through-channels operation pausing briefly at each channel and continuing without requiring any further input, e.g., the pressing of a key, by the user until commanded by the user to stop scanning, such as by the user depressing a key or taking other action. Document FR-A-2 639 499 (Bellot) shows a remote control having a "SCAN" key for issuing a "SCAN" command.
This feature is desirable even for remote controls that have channel "UP" and channel "DOWN" keys since the ability to automate the process of scanning channels reduces the number of key or button presses required to be made by the user.
SUMMARY OF THE INVENTION
Various aspects of the present invention are defined in the independent claims. Some preferred features are specified in the dependent claims.

The manner in which these pushbuttons 25, such as the "CHANNEL UP" key 26, the "CHANNEL DOWN" key 27 and a "SCAN" key 28, are utilized in operating the control 10 will be described in greater detail hereinafter.
FIG. 2 is a side view of the remote control 10.
As shown in FIG. 3, at a top or forward end 29 of the remote control 10 there is provided an opening or window 30 for at least one infra-red light emitting diode, LED 1. Also, on the top surface 18 (FIG. 1) of the upper housing member 12 of the remote control 10, there is provided another light emitting diode, LED 2, by which information be communicated to the user of the remote control 10.
The infra-red light emitting diode LED 1 is held securely in place in the window 30 and is adapted to be aimed at a home entertainment device to be controlled. The diode LED 1 is generally in alignment with diode LED 2 and is coupled to an electrical circuit 36 (FIG. 3) of the remote control 10.
The light-emitting diode LED 2 is generally centrally located for indicating when an individual key 25 is pressed on the remote control 10. The diode LED 2 a visible indicator that the remote control 10 is working. If the diode LED 2 does not light when a key 25 is pressed, the batteries may need to be replaced.
FIG's. 4a and 4b are a block electrical schematic circuit diagram of the electrical operating circuit 36 which is mounted in the remote control 10 and which includes a microprocessor 38, including a RAM, a ROM and a CPU. The keypad 20 is coupled to the microprocessor 38 by an interrupt line 46, a plurality of switch contact lines 47 and a bus 48 to the CPU.
The keypad 20 has input switch cross-points 49 which are located beneath the keys 25 and which are coupled to the CPU for remotely controlling a home entertainment device.
As shown in FIGS. 4a and 4b, each cross point 49 has a unique pair of input ports to the CPU, to determine which key(s) were pressed to execute a function associated with such key(s).
A power supply in the form of a battery is connected between a + voltage input 51 to the microprocessor 38 and a system ground 52. A backup battery 53 is connected from ground 52 through the input 51 and an isolation diode D1 to a VDD input of the CPU to maintain the data stored in the ROM and/or RAM thereby to provide a non-volatile system.
Coupled to a reset input RST of the CPU is a reset circuit 55 including a voltage divider 56 for causing the CPU to reset and re-initialize itself when battery power is applied.
Power is applied to the CPU through the isolation diode D1 to input VDD. Capacitors C1 and C2 provide power supply filtering for the power line.
An oscillator circuit 57 provides a clock frequency for the CPU.
The circuit 36 includes pull up resistors R1-R5, to keep the input ports and the IRQ line to the CPU at a known state when the keys 25 are not depressed. The circuit 36 further includes isolation diodes D2-D5, providing an "or" logic function circuit 58 for isolating each line from the other while not inhibiting communication to the IRQ input of the CPU. Each diode D2-D5 prevents action in one line from spurious indicating action on another line, while still permitting each line individually to send a signal to the IRQ input of the CPU.
The CPU includes an output PB5 to the light emitting diode LED 2 to indicate when a key 25 has been pushed and the circuit 36 is sending an infra-red signal through infra-red light emitting diode LED 1. The CPU also includes an output PA7 to a transistor 60 of an IR lamp driver circuit 62 which outputs a voltage to the light emitting diodes LED 1 and LED 2 for allowing a signal to flow through the transistor 60, and activate the infra-red light emitting diode LED 1 for controlling an home entertainment device.
According to the teachings of the present invention the remote control 10 is provide with the SCAN key 28 (FIG. 1) by which the channel scan function of the present invention be initiated.
It is to be noted that the electrical circuit 36 is generally of the type disclosed in greater detail in the Darbee et al U.S. Patent No. 4,959,810, of which this application is a continuation-in-part and the disclosure of which is incorporated herein by reference.
The operating program for the remote control 10 which is stored in the ROM or RAM is very similar to the operating program disclosed in the Darbee et al U.S. Patent No. 4,959,810 which is incorporated herein by reference.
Referring now to FIG. 5 there is illustrated therein a flow chart of the steps performed by one embodiment of the channel scan software/program of the present invention which is incorporated into a remote control 10 which already has channel "UP" and channel "DOWN" keys supporting a channel up and channel down function and which has incorporated therein the SCAN key 28 which be operated by the user of the remote control 10 for effecting an automatic channel scan according to the teachings of the present invention.
As shown, at the initial step, the SCAN key 28 is pressed which causes the remote control 10 to transmit "channel up" IR code.
Then the question is asked, "Have three seconds elapsed since the last transmission?" If the answer is yes, the program loops back to the previous step and repeats the just described procedure.
If the answer is no, another question is asked, "Has any key been pressed?" If the answer is no the program loops back to the previous question.
If the answer is yes, the program is completed and the program exits to DONE.
From the foregoing description, it will be apparent that the remote control 10, with the SCAN key 28 and the channel scan software stored therein, of the present invention has a number of advantages, some of which have been described above and others of which are inherent in the invention. Also, it will be understood that modifications be made to the remote control 10 and the channel scan software therein and described above without departing from the teachings of the invention. Accordingly, the scope of the invention is only to be limited as necessitated by the accompanying claims.
