2 is a schematic block diagram of a DCD player 100 according to the present invention.

The DCD player 100 is largely comprised of the engine 120 and the host 140. Here, the engine 120 is a DCD driver that accesses the DCD 110 so that data can be recorded and read. The host 140 controls the operation of the engine 120 while interfacing data with the engine 120. In addition, the host 140 is connected to an external device, for example, a personal computer (PC) 200 to control the engine 120 from the PC 200, and to communicate the data with the engine 120 It is connected to the interface to receive the source data and control code from the external PC 200 to the engine 120, the role of the interface, and receives the data read from the DCD (110) from the engine 120 to play back It acts as a playback device.

The engine 120 includes a spindle 121, a DCD pickup unit 122, a spindle 124, a pickup driving unit 125, an engine memory 126, an engine buffer 127, and an engine control unit 128.

The DCD pickup unit 122 records and reads data under the control of the engine controller 128 with respect to the mounted DCD 110. The spindle driver 124 and the pickup driver 125 drive the spindle 121 and the DCD pickup unit 122 under the control of the engine controller 128. The engine buffer 127 temporarily stores data to be recorded and read data when the engine pickup unit 122 records or reads data from the DCD 110. The engine buffer 127 may use SRAM. The engine memory 126 stores code values for various commands promised between the engine unit 120 and the host 140, and a program for operating the engine unit 120 is stored. At this time, the flash memory 126 is used as the engine memory 126.

The engine controller 128 receives a command transmitted from the host 140, and according to a program stored in the engine memory 126, the DCD pickup unit 122, the spindle driver 124, the pickup driver 125, and the engine buffer. Control 127. In addition, the engine control unit 128 includes a register unit 128-1 consisting of four registers for use in communication with the host 140.

The register unit 128-1 is composed of a control register 128a, a status register 128b, a byte counter register 128c, and a data register 128d, and each register performs the following operations.

The control register 128a records function control and interface interrupt enable / disable information by the host 140, and controls the respective blocks of the engine by reading the values from the engine controller 128.

The status register 128b records and reads status information and interrupt reason information from the engine 120, and reads the information from the host 140 to perform control according to the read information.

Byte counter register 128c performs both write and read operations at host 140 and engine 120, respectively. However, the host 140 can write to the byte counter register 128c only when the set BUSY bit of the status register 128b is clear, and the set data DATA bit of the status register 128b is set. If only, read valid information is read from the byte counter register 128c. The byte counter register 128c contains the byte count for subsequent command, data, or status mode transfers.

The data register 128d may also be read and written in both the host 140 and the engine 120. However, the host 140 writes to the data register 127d while in the command and data out phases, and in the engine 120, status and data in phases. Data register 127d is read during the operation.

The host 140 includes an input unit 142 equipped with a key input unit 142a and a voice input unit 142b, a host memory 143, a USB interface 144, a liquid crystal display (LCD) 145, and an audio codec. And an audio output unit 146 and a host control unit 141, each of which comprises a 146a and an amplifier 146b.

The key input unit 148 includes command keys such as selection, playback, recording, skipping, and volume provided to enable a user to input a command regarding the operation of the DCD player 100.

The host memory 143 stores code values for various commands promised between the host 140 and the engine 120, and programs related to operations of the engine 120 and the host 140 are stored. The flash memory 143 can be used as a storage means.

The USB interface 144 is provided to allow external devices such as the DCD player 100 and the PC 200 to interface data with each other.

The host controller 141 may include a plurality of timers 141a for temporal control of the system, an OSD processor 141b for providing various character information to be displayed on the LCD 145, and a plurality of reservation commands for storing the plurality of reservation commands. It includes a buffer 141c. In addition, if the host controller 141 does not receive a command regarding the operation of the engine 120 from the key input unit 142a while the device is powered on, the engine 120 is connected to the engine 120 through an interface with the engine 120. Transmits a power control command requesting the power saving mode to be performed, and displays the operation state of the engine 120 switched according to the power control command on the LCD 145. Of course, by installing a separate LED (Light Emitted Display) to display the operating state of the engine 120 to change the color of the LED according to the operating state of the engine 120, or to install a plurality of LEDs of the engine Depending on the operating state, the corresponding LED may be made to emit light.

The DCD player 100 includes the above components, and a process of transmitting a command from the host 140 to the engine 120 will be described with reference to FIG. 3.

First, the host 140 checks the BUSY bit in the status register 127b of the engine 120 before issuing a command. At this time, when the busy bit is clear, the engine 120 determines that the command can be received. If the busy bit is set, the host 140 transmits to the engine 120. Clear the busy bit by sending a command to clear the busy bit. In this way, if the busy bit is cleared, the host 140 writes a reset byte count pointer function code into the control register 128a so as to be an address alignment. Host 140 then writes the size of the command packet to byte counter register 128c, then writes a " start command funcrion code " to control register 128a and sets the IRQ bit ( M2). Then, the engine 120 reads the size of the command packet from the byte count register 128c, processes it as an error if the size of the command packet is zero or more than the maximum size, and otherwise receives a command, that is, the command mode. The state transitions to M3.

When the IRQ bit of the control register 128a is set by the host 140, the engine unit 120 reads the byte count register 128c and switches from the idle mode M1 to the command mode M3. Is as follows. When switching from the idle mode M1 to the command mode M3, the engine unit 120 sets the control / data bits of the contents of the status register 128b and read / write (RD / WR). Clear the bit. Next, the engine unit 120 sets the IRQ bit. When the IRQ bit is set by the engine unit 120, the host 140 writes a command packet byte to the data register 128d of the engine unit 120. When the instruction packet byte is written to the data register 128d, the engine unit 120 enters the instruction mode M3 for executing the instruction by clearing the data bit of the status register 128b.

A write or read operation is performed in the data mode M4 in accordance with the contents of the command in the command mode M3. In the case of a read operation, the host 140 reads the data register 128d. On the other hand, in the recording mode, the host 140 writes data to the data register 128d. When data mode M4 is complete | finished, it progresses to status mode M5.

In the status mode M5, the host 140 checks the status of the current engine unit 120 by reading the status register 128b. If the current status is confirmed, read the byte counter register 128c and the data register 128d again to check the contents to be transmitted, then terminate the command and enter the idle mode (M1) again. At this time, if a command is input from the outside, the process is repeated.

On the other hand, the DCD player 100 performing the function through the above process is to perform a power saving mode when a certain time operation command is not input from the user, the DCD player according to the present invention with reference to the flow chart of FIG. Look at the process of power saving mode and how to display it.

First, when the DCD 110 is inserted into the DCD player 100 while the power is supplied (S10), the host controller 141 receiving the disk insertion signal from the engine 120 receives the DCD into which the engine 120 is inserted. The first power control command is transmitted to operate in a ready state in which the spindle 121 is rotated at a high speed so as to be immediately accessed with respect to 110 (S20). Next, the host controller 141 transmits a control command to display the ready state of the engine 120 on the LCD 145 through the OSD 141b (S30). If the command regarding the operation of the engine 120 is not input through the input unit 142 until the ready operation state of the engine 120 reaches the first set time as described above (S40), the host controller 141 may determine the engine. In operation S50, the second power control command is transmitted to the engine 120 so that the 120 operates in an idle state of lowering the rotation speed of the spindle 121. The host controller 141 transmits a control command to display the idle state of the engine 120 on the LCD 145 through the OSD 141b (S60). Thereafter, if a command regarding the operation of the engine 120 is not input through the input unit 142 so that the idle state of the engine 120 becomes the second set time (S70), the host controller 141 may determine that the engine is in the power saving mode. In operation S80, the third power control command is transmitted to the engine 120 to operate in a coma state. In addition, the host controller 141 transmits a control command to display a coma state on the LCD 145 through the OSD 141b (S90).

The host controller 141 transmits a first power control command to the engine 120 when a command regarding the operation of the engine 120 is input from the input unit 142 while the engine 120 is in an idle state or a coma state. do. The host controller 141 also displays the ready state on the LCD 145 through the OSD 141b.

As described above, the digital convergence disc player for displaying the operation state according to the power saving mode and the control method thereof according to the present invention perform the power saving mode when the user's command is not input for a predetermined time while the DCD is mounted on the engine. In addition, the operating state of the engine can be recognized by the user so that unnecessary power control is not repeated.
