The present invention relates to a remote controller and a receiving apparatus corresponding to data broadcasting of a digital television, and a signal transmission method thereof, and more particularly, to give an ID value to each remote controller so that the receiver recognizes each remote controller independently. .

Currently, digital broadcasting is being broadcast, large screen digital broadcasting receivers are rapidly spreading, and set-top boxes capable of receiving digital broadcasting are also being distributed. Later, when data broadcasting becomes commonplace, many homes will see true digital broadcasting. Accordingly, if data broadcasting services become full-scale in the future, many people will use data broadcasting more.                         

1 shows a state of use of a conventional television remote control.

According to the current data broadcasting standards, only one remote control is supported. In addition, even if there are two remote controllers 102, the signals of the two remote controllers 102 are treated as one remote controller 102 without distinguishing the signals. However, more diverse data broadcasting services need to support services for multiple users.

For example, a simple game among data broadcasting services may be more interesting if it supports two-person game service than one-person game. In order to support such a two-player game service, two input devices (remote control, wireless keyboard) are also required.

An object of the present invention is to provide a definition and operation method of a hardware device (remote control) for multi-user input that will be raised in the future in digital data broadcasting services.

Another object of the present invention is to provide a remote controller capable of serving two or more users at the same time in a data broadcasting service.

In order to achieve the above object, the remote controller 300 for the multi-user of the digital television of the present invention includes a button unit 301 for signal input, a database 307 including remote controller key-code data and ID data, Remote control key-code generation unit 302 for extracting the corresponding key-code according to the button input from the database 307, and ID data insertion for generating remote control key-code signals by inserting ID data into the remote control key-code. And a transmitting unit 304 to 306 for modulating the remote control key-code signal into a wireless signal.

The present invention preferably further comprises an ID input button for generating an ID of the remote controller.

The ID generated in the present invention is preferably stored in the database 307.

Receiving apparatus 200 for receiving and operating a signal of the remote control 300 of the present invention includes a receiving unit (201 ~ 203) for receiving a radio signal and modulating the remote control key-code signal, and the remote control key-code signal and the ID data A remote controller key-code input unit 204 for separating the remote controller key-code, a remote controller key-code analyzer 206 for interpreting the separated remote controller key-code, and an ID data analyzer for interpreting the separated ID data 205.

A method of transmitting a signal of the remote controller 300 of the present invention may include a) selecting an operation, b) generating a key-code according to the selected operation, c) including ID data in the key-code, and d ) Modulating and transmitting the key-code signal including the ID data into a wireless signal.

The transmission method determines whether the ID input button is pressed before step a), and if the ID input button is pressed, converts the input ID value into a database 307 and terminates, otherwise starts step a). It is preferable to further include the step.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

2 is a schematic diagram showing a remote controller 300 and a receiving apparatus 200 according to an embodiment of the present invention.

In an alternative embodiment, the receiver 200 includes an IR receiver 201, an RF receiver 202, and a Bluetooth receiver 203.

The above embodiment schematically shows how a signal of the remote controller 300 is received.

Referring to FIG. 2, the present invention recognizes a plurality of remote controllers 300 by one television or set-top box (hereinafter, referred to as a "receiving device"). The number of the remote controller 300 is not limited, and the number may be determined as necessary. The remote controller 300 is each given a specific ID. When the remote controller 300 transmits a signal including each ID data in the signal, the receiver 200 analyzes the corresponding ID to recognize each remote controller 300. The ID may be given to the remote controller 300 arbitrarily by the user.

The transmission protocols of the remote controller 300 and the receiver 200 may adopt various transmission methods and protocols such as RF, IR, Bluetooth, and the like, and may use them. The transport protocol is not limited to the above scheme. It will be apparent to those skilled in the art that various communication protocols other than the above are used in the invention.

3 is a diagram illustrating a signal flow according to an embodiment of the present invention.

The embodiment schematically shows the flow of a signal transmitted from the remote controller 300 to the receiver 200.

Referring to FIG. 3, first, a user presses a button 301 provided in a remote control to operate a television. The operation of the television is an act of changing the channel or raising the volume.

When a button operation by a user is performed, the remote control key-code generation unit 302 generates a key code corresponding to the operation button. The key-code is stored in the database 307. The key-code value stored in the database 307 is preferably arbitrarily determined by the provider.

After the corresponding key-code is generated by the button operation, the ID data inserting unit 303 generates a key-code signal by including its ID in the key-code. The ID data can be inserted by simple signal synthesis. The ID data is also stored in the database 307. It is preferable that a corresponding ID of each remote controller 300 is predetermined by a provider or randomly assigned by a user.

The key-code signal is input to the transmitter and transmitted wirelessly. As described above, the transmission method can use a method or protocol that is obvious to those skilled in the art in accordance with the purpose of the invention. In the present invention, the preferred embodiment uses IR, RF, and Bluetooth.

The transmitted radio signal is input to the receiver of the receiver 200. The receiver is provided with a device corresponding to the transmission method and protocol of the transmitter. The receiver modulates the received radio signal into a remote control key-code signal.

The remote control key-code input unit 204 separates the modulated remote control key-code signal into a remote control key-code and ID data.

Among the separated signals, the ID data is interpreted by the ID data analyzer 205, and the receiver 200 recognizes the remote controller 300 based on the interpreted ID value, and the remote controller key-code is a remote controller key-code. Recognized by the analyzer 206, the receiver 200 performs a command corresponding to the recognized key-code value.

4 is a flowchart showing a method of operating a basic remote controller 300 according to an embodiment of the present invention.

The embodiment includes generating a key-code (S401), adding a unique ID (S402), and outputting a signal (S403).

Referring to FIG. 4, step 401 is a process of generating a corresponding key-code according to a button input. The key-code is preferably generated by extracting it from the database 307 of FIG.

Step 402 is a process of adding unique ID data. The ID data allocated to each of the remote controllers 300 is added to the key code generated in step 401. The step can be accomplished by the ID data inserter. The value of ID data is also preferably extracted from the database 307 and used.

In step 403, the composite data is output. A signal obtained by combining the remote control key-code data and the ID data is modulated by a radio signal at the transmitter and output.

Hereinafter, the present invention will be described in more detail with reference to preferred embodiments. However, this embodiment is only presented to understand the content of the present invention and should not be construed that the scope of the present invention is limited to these embodiments.

5 is a flowchart showing the operation of the remote controller 300 according to an embodiment of the present invention.

The embodiment may include checking whether an ID input button is operated (S501); Generating a key-code by button input (S502); Adding a unique ID (S503); Transmitting a signal (S504); And processing the inputted ID value during the operation of the ID input button (S505).

In the above embodiment, each of the remote controllers 300 is provided with an ID input button so that the user can be given an arbitrary ID, and checks the operation of the ID input button, and schematically shows the operation accordingly.

A description with reference to FIG. 5 is as follows.

Step 501 is a process of determining whether the ID input button is operated. The remote controller 300 according to the present embodiment includes a function for setting an ID value for each remote controller 300. Therefore, the remote control button unit 301 is provided with a button for inputting the ID. Therefore, the remote controller 300 determines whether the manipulated button is an ID input button or a button for operation of the receiver 200 when the user manipulates the button.

Steps 502 to 504 are the same as steps 401 to 403 of FIG.

In step 505, when the ID input button is operated in step 501, the operation is indicated. When the ID input button is operated, the remote controller 300 stops the signal generation process of steps 502 to 54 and enters a standby state to receive input of an ID value. When the user wants to arbitrarily designate or change the ID value of the remote controller 300 currently used, the user inputs a desired ID value after pressing the ID input button. The input ID value is stored in the database 307 inside the remote controller 300. After the reset as described above, the remote control key-code signal generated by the user's button input includes the changed ID value.

FIG. 6 is a flowchart illustrating an operation of the receiver 200 for receiving a signal of the remote controller 300 generated in FIG. 5, which is an embodiment of the present invention.

In the above embodiment, the receiving operation may include determining whether an ID value exists (S601); Recognizing the remote controller 300 corresponding to the received ID value (S602); Performing a function corresponding to an input signal with priority based on the ID value (S603) and performing a function corresponding to a general input signal (S604).

Referring to FIG. 6, step 601 is a process of checking whether an ID value of the corresponding remote controller 300 is included in the received wireless signal. The check is preferably provided in the receiver in the receiver 200. In the above step, only the ID value is checked and the remote controller 300 is recognized according to the corresponding ID value. If not, the receiving device 200 is a signal generated by the general remote controller 300. The action is performed.

Step 602 is a process of recognizing the included ID data.

If it is checked in step 601 that the radio signal contains ID data, the ID value is read out to distinguish each remote controller 300 and give priority to the remote control 300. The above process is preferably performed in the ID data analysis section described in FIG.

Step 603 is a process of executing a command requested by the user. In the steps 601 and 602, when the prioritization and recognition process by ID identification of the corresponding remote controller 300 is completed, general operations such as channel switching and volume raising are performed.

In step 604, when the ID value is not checked in step 601, the controller 610 determines a general remote control signal to perform a known function.

7 is a flowchart illustrating an operation of the receiving apparatus 200 according to another embodiment of the present invention.

Since the operation of the remote controller for the operation of the embodiment is the same as described with reference to FIG. 4, only the operation of the reception apparatus 200 will be described below.

In the above embodiment, the receiving operation may include determining whether an ID value exists (S701); Determining whether the database of the checked ID value exists in the database 307 (S702); Extracting priorities of the remote controller 300 corresponding to the corresponding ID value (S703); Performing a function corresponding to an input signal with priority based on the ID value (S704) and performing a function corresponding to a general input signal (S705).

In the above embodiment, a unique ID value is set for each remote controller 300 and the value is read and set to be recognized by the specific remote controller 300 inside the receiver.

Referring to FIG. 7, step 701 is similar to step 601. In step 601, only the ID value is checked. However, in step 701, the value is read.                     

Step 702 is a step of determining whether the ID value recognized in the step 701 is included in the database 307. The ID value is preferably increased in the range in order to reduce the probability that the remote controller 300 using the same ID may occur. For example, when the length of the ID value is 32 bits, the probability that the two remote controllers 300 are the same ID is 0.0000000232%. In the above step, if the read ID value is not included in the database 307, step 705 is performed, which is a general function performing step.

In step 703, when the ID value recognized in step 702 is included in the database 307, the priority of the remote controller 300 corresponding to the recognized ID value is extracted from the database 307.

Steps 704 and 705 are the same as steps 603 and 604, and thus description thereof is omitted.

As described above, according to the present invention, there is an effect capable of supporting multiple users in a data broadcasting application.

And, without having to purchase several remotes, the remote controllers of the same company can be recycled using compatibility between remote controllers of the same company.

It is also easy to apply to existing technology without additional hardware development or cost for new technology.

As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified without departing from the spirit and scope of the invention described in the claims below. And can be changed.
