The present invention relates to a remote control interface of a personal computer system, and in particular, a keyboard BIOS is used to convert data transmitted wirelessly by a user into a data format that can be recognized by a PC system so that a user program can be utilized and various types of CD media. The present invention relates to a multi-variable multi-changer remote control interface device of a PC system, which can be easily controlled by using a remote control without the inconvenience of replacing the same.

1 is a first embodiment of a remote control interface device of a conventional PC system.

As shown, a keyboard 1, a mouse 2, a keyboard controller 3 for generating a signal according to the operation of the keyboard 1 and the mouse 2, and a signal obtained from the keyboard controller 3 According to the PC system 4 to control the system.

In the figure, KCLK is the keyboard clock line, KDATA is the keyboard data line, MCLK is the mouse clock line, MDATA is the mouse data line, TRQ1 is the interrupt line that transfers the data received from the keyboard to the PC system, and IRQ2 is from the mouse. An interrupt line that delivers the received data to the system.

And XD _0- XD ₇ are data buses between PC system and keyboard controller.

In the interface device having such a configuration, the keyboard 1 and the mouse 2 and the PC system 4 implement the wired serial interface.

Here, the serial interface sends and receives 11bit data continuously through any I / O port. The 11 bits are composed of one bit of start bit, eight bits of data bit, one bit of parity bit, and one bit of stop bit.

On the other hand, when the keyboard 1 and the mouse 2 send data, the clock and data lines are dropped to the low level to display pseudo signals and to clock to transmit 11 bits of data.

At this time, if the keyboard controller 3 recognizes the system command before transmitting the 10th bit (perity bit) during the data transmission, the system command is executed with priority, ignoring the previous data transmission.

2 is a second embodiment of an interface device of a conventional PC system.

As shown, an input device 5 such as a tablet or pen for signal input, an input device controller 6 for recognizing a signal of the input device 5, and an output signal of the input device controller 6 are connected to a PC. It consists of an AT bus 7 for delivery to the system 8.

The interface device having such a configuration corresponds to a case where a separate input device 5 (for example, Tablet, pen .....) other than a keyboard or mouse is used, and an input device controller (6: option card) and a user interface program that recognizes and uses corresponding input data.

Here, the input device controller 6 converts the data sent by the input device 5 and transmits the data to the PC system 8 using the AT bus 7.

At this time, IRQ, I / O address, Memory address, etc. are selected in advance so as not to conflict with other devices.

3 is a configuration diagram of a conventional CD-ROM drive device.

As shown, a CD 9 in which data is recorded in a 16-bit data format, a pickup 10 for reading data recorded on the CD 9, and a sub-unit 11 for controlling the position of the pickup 10. ), The digital signal processor 12 for converting 16-bit data read from the pickup 10 controlling the speed into 8-bit data, and the 8-bit data processed by the digital signal processor 12 in the IDE interface format. The decoder 13 decodes the correct data, and the digital / analog converter 14 converts the digital signal output from the digital signal processor 12 into an analog signal.

Referring to the operation of the conventional CD-ROM drive device configured as described above is as follows.

First, the data recorded on the CD 9 is optimally controlled by the servo 11 using the servo 11 to read 16-bit data.

The 16-bit data is converted into 8-bit data by the digital signal processing unit 12, and the digital signal processing unit 12 controls the speed (double speed, quadruple speed ...) through spindle control.

The data converted by the digital signal processor 12 is output as an analog audio signal through the digital / analog converter 14, or decoded by the CD-ROM decoder 13 and transferred to the PC.

However, such a conventional interface device has the following problems.

The interface device of FIG. 1 has only two input devices, a keyboard or a mouse. Since the wired serial interface is used, the working range is limited to the range where the keyboard and mouse are connected. Cannot be guaranteed.

In the interface device of FIG. 2, the input device controller (option card) transmits data using the AT bus so that the user can check the jumper setting of the option card so as not to conflict with the previously used IRQ, I / O address, and memory address. There was an inconvenience to change.

In the case of FIG. 3, the multi-purpose CDs (AUDIO CD, VIDEO CD, CD-ROM TITLE, etc.) are played, and the user satisfies ATAPI (AT attach packet inerface) standard and uses an application program to control the CD media. In order to use an application, there are restrictions that must be familiar with the operating system (OS) in which the application is operated.

Accordingly, the present invention is to solve the above problems of the prior art, an object of the present invention is to convert the data transmitted by the user wirelessly using a keyboard BIOS to a data format that can be recognized by the PC system user program The present invention provides a remote control interface device of a PC system that can be utilized and made simple to use as a remote control without the inconvenience of replacing various kinds of CD media.

Hereinafter, described in detail with reference to the accompanying drawings of the present invention.

4 is a first embodiment of a remote control interface device of the PC system according to the present invention. As shown, an infrared transmitter 100 for transmitting infrared rays, an infrared receiver 101 for converting infrared rays transmitted from the infrared transmitter 100 into serial data that can be recognized by a keyboard controller, and the infrared receiver 101 The interface controller 104 interfaces the signals obtained from the keyboard 102 and the mouse 103, and retrieves the parity of the data obtained from the interface controller 104 and transfers the data to the PC system 106. A keyboard controller 105 for transmitting a command to each device, and a PC controller 16 which receives remote controller data from the keyboard controller 105 and stores the data in a specific DRAM, transmits a remote controller ID byte to a keyboard buffer, and performs a desired task. Configured.

The operation and effects of the PC system remote control interface device according to the present invention configured as described above will be described in detail with reference to FIG. 5.

First, when a key provided in the remote controller is pressed, the infrared ray transmitting unit 100 corresponds to the pressed key and transmits a key code to infrared rays. At this time, ID byte representing remote control data is sent first to distinguish it from keyboard data. (This value should be a non-keyboard Stancode value.)

As an example, Make code = F5h 02h, Breake = F5h 82h (F5h = ID byte).

On the other hand, when the infrared rays are transmitted as described above, the infrared receiver 101 receives them and converts them into a serial data format that can be recognized by the keyboard controller 105.

Here, the remote control receiver program should include a routine to check the validity and timeout when sending the serial data format.

When the remote control data is sent to the keyboard controller 105 through the interface controller 104, since the keyboard data format is used, a code different from the existing keyboard scan code is used so as not to affect the user program.

The interface controller 104 then interfaces this to the keyboard controller 105. That is, the interface of the existing keyboard 102 and the mouse 103 is maintained and the remote controller interface is implemented without changing the program of the keyboard controller 105.

In more detail, in order to maintain the protocol between the existing keyboard controller and the input device, it is necessary to check all possible actions between them to act as a keyboard controller and to add a remote controller interface routine.

In addition, it is connected to the infrared receiver 101 with two port pins of IR CLK and IR DATA, and by executing the remote control data read by this port (when KCLK1, KDATA1 = 0 or MCLK1 = 1, MDATA1 = 0) It passes to the keyboard 102 and the mouse 103.

In this case, the remote control control program checks whether the system command process and the receiving process have corresponding actions, and gives priority to the dual system command process.

In addition, the system command process recognizes the command process that the PC system 106 sends to the keyboard controller 105 via the I / O address 64h (KCLK1 = 1, KDATA1 = 0), and the keyboard 102 and the mouse 103 are recognized. To pass.

At the beginning of the command process routine, each clock is pulled low to prevent data loss in case the remote controller, keyboard, or mouse sends data.

Next, in the reception process, when each device sends data to the interface controller 104 (IRCLK = 0, IRDATA = 0 or KCLK = 0, KDATA = 0 or MCLK = 0, NDATA = 0), the remaining devices are checked. Disables it.

For example, in the case of receiving remote control data, the remaining devices (keyboard and mouse) are disabled, and at this time, the remote controller data is transmitted to the PC system BIOS or the device driver program by sending the remote controller ID bytes received from the infrared receiver 101 to the keyboard controller 105. Recognizing that it is ready to receive the next real remote control data and then send the actual remote control reception data to the keyboard controller 105 can be delivered to the system through the IRQ1 service.

When the PC system 106 receives the remote control data through the I / O address 60h, the PC system 106 stores the remote control data in a specific DRAM area and transmits the remote control ID byte to the keyboard buffer located at the I / O address 40h to the CPU AH register. Sending a remote control ID byte causes the application to check the ID byte and perform the desired operation.

6 is another embodiment of the present invention.

As shown, it is configured to be able to use multiple infrared transmitters. At this time, each of the remote control devices 100 and 107 assigns a different ID # to check the device type in the infrared receiver 101.

First, the infrared transmitter 100 uses RMTCLK and RMTDATA, and the other remote control trackball 107 transmits data using TRK CLK and TRK DATA.

The interface controller 104 also distinguishes data from the infrared transmitter 100, the remote control trackball 107, the keyboard 102 and the mouse 103 so that the PC system 106 receives the data through the keyboard controller 105.

7 is an example of applying the present invention to a multi-changer system.

As illustrated, the PC system 106 and the CD-ROM multichanger 109 are connected to the IDE interface 108.

The operation of the interface device configured as described above is as follows.

First, the infrared transmitter 100 transmits data including an ID byte.

Then, the infrared receiver 101 receives the data transmitted by the infrared transmitter 100, converts the data into a serial data format, and transmits the data to the keyboard controller 105. At this time, a confirmation code F5 is sent first before sending the actual command data to indicate that the command of the remote controller, and if the keyboard controller 105 receives a 5 command which is a response code for the F5 code is received, the actual data is sent.

The keyboard controller 105 then performs an action determined according to the data to be received by the user program. For example, if the CD PLAY code of the remote control is 19h, it is checked and the CD PLAY command is sent through the IDE interface 108 to perform an actual action.

At this time, the command related to the CD-ROM multi-changer 109 using the IDE interface 108 is composed of 1 byte of CD NUMBER (number of CD to be controlled) and 1 byte of command.

However, since the 1-byte command has only a command command, the CD multi-changer also needs to include a selection number of the CD. To do this, the following command type is transmitted.

The command is sent in the form of 2 bytes, and the first 3 bits are used to select the CD of the CD multichanger. And the remaining 13 bits are used for commands such as playstop. For example, if a command of 0111 0001 1101 1111 comes in, the first 3 bits represent 3, so it selects CD 3 and executes the command corresponding to the remaining 1 0001 0010 1111. Done. Since the CD selection field is 3bit, it is possible to designate 0 ~ 7 (8CD change) and the command field is 13bit, so it can support many 8K commands. In this way, it is possible to select a CD and send the corresponding command. Since each CD has a different type, it reads audio-CD, CD-ROM, CD-DA, CD-RW, etc. It runs on the PC and controls the selected CD.

As described above, the present invention supports the wireless remote control interface, so that the PC based user program can be controlled at a short range.

In addition, if the remote control transceiver is diversified to implement a remote control keyboard or a remote control trackball, the text based program can wirelessly input the remote control keyboard, and in a GUI environment, the remote control trackball can be used as a wireless mouse.

In addition, the PC remote control interface, which was previously supported only by a single CD-ROM drive, is extended to the CD-ROM multi-changer, thus providing the convenience of using a CD-ROM multi-changer.
