Description

Standby operation control method and device for an optical disc player

The present invention relates to a standby operation control method and apparatus for an optical disc reproducing apparatus, and more particularly, to a standby operation of an optical disc reproducing apparatus capable of receiving a signal from the outside even when the system is not operated.

Digital Video Disk (DVD), which is gaining popularity as a new information recording medium, is an optical disk with a diameter of 12 centimeters, and its appearance is similar to that of a conventional compact disk, but the structure of the disk, signal modulation technology, and recording of the disk It is a next-generation information storage medium having a density of about 5 gigabytes (5 GBytes) in a cross section with improved density and accuracy of a playback device.

The DVD has a capacity of storing about 135 minutes of video when storing image information using MPEG-2 (Moving Picture Experts Group-2) technology, which can record an entire movie title. It is expected to be a multimedia medium that replaces conventional video tapes and CDs due to its large capacity.

A conventional optical disc reproducing apparatus for reproducing the DVD is shown in FIG.

The optical pickup device 15 reads data from the DVD 1, which stores data such as video, audio or text information, converts the data into an electrical signal and outputs the converted data. The data output from the optical pickup device 15 is input to a demodulator 7 which performs analog signal processing such as amplification and signal compensation, converts it into a digital signal, and then demodulates and outputs the digital signal.

Data including an error generated in the bit stream output from the demodulator 7 is input to an Error Correctin Code (hereinafter referred to as ECC; 17). The ECC unit 17 compensates and outputs an error generated during a disc playback process, an error caused by a disc damage, an error generated during a disc transfer process, and the like.

The data decoded by error correction as described above is decompressed and decompressed by the MPEG decoder 9, and then decoding of video data, subtitle data, audio data, and the like is performed. The data output from the MPEG decoder 9 is converted into an analog signal, and then converted into a broadcast signal for display on a television receiver or the like, and outputted, thereby reproducing the data recorded on the DVD 1.

Until the playback of the DVD 1 is performed by the above process, a command from the user is received through the key input unit 19 to perform control accordingly, and the demodulator 7, the ECC unit 17, and the decoder ( 9) The system 11 receives the system data and the like so that the controller 11 performs system control necessary in the signal processing process.

In order for the DVD 1 to be reproduced in this manner, the control unit 11 must first perform a control operation according to the following procedure.

When a power-on command is input through the key input unit 19, the control unit 11 recognizes that the input key is a command to start the system according to a user's request, and supplies power to each circuit unit to the power supply unit 21. Outputs a control signal.

That is, until there is a power-on command through the key input unit 19, the power output through the power supply unit 21 is not present. Only the control unit 11 and the key input unit 19 is in a state in which power is supplied by the internal battery power supply unit 19 or the external battery power supply unit 23, in which case the control unit 11 is powered on from the outside. It is a stand-by state for key signal input.

Then, the controller 11 recognizes the power-on key signal, and then power is supplied to each circuit part by a control signal applied to the power supply part 21, and all circuit parts of the system are operated according to the reproduction of the DVD 1. There is a waiting state that can be achieved.

That is, most systems including the conventional optical disc reproducing apparatus, when powered off by the user's request, deactivate the devices that are not used in order to reduce power and heat consumption due to the operation of the system. Only the key input unit and the host control unit that can recognize the input key signal are activated. It will wait for the power-on state.

Therefore, the standby state provided in the conventional optical disc reproducing apparatus is a state in which only the control unit 11, which is a host control means, is activated, and in this state, any signal processing of itself, for example, data input / output processes with the outside, can be performed. I can't. Only power-on key signal input can be recognized.

However, the market for DVD, which is expected in the next generation, is more likely to be formed in the form of rental of a disc than the sale of a disc. In the system for renting a disc, a standby state of a conventional optical disc reproducing apparatus is provided. There is a part that cannot be solved.

The system for renting discs has been conceived in that it cannot accommodate both consumer and producer demands in the rental market in which data of the current movie and audio portion is recorded on magnetic tape and rented to consumers. Therefore, the newly proposed method of the DVD rental system allows the post-management of discs sold to consumers through the network.

For the follow-up management of the sold disc, it is necessary to provide notification information according to the follow-up management from the supplier side providing the disc to the consumer side. For example, a supplier should provide consumers with the disc's playing time, playing cost, and advertisement information for a new disc in a timely manner so that consumers can take action.

The provision of information from the supplier side to the consumer side of this type should be made at a time when the possible consumers do not feel inconvenience in using the system, and this time is described as a waiting time when the consumer does not use the system. However, the waiting time set in most devices maintains the same shape as the standby state provided in the conventional optical disc player.

That is, the standby state of the conventional system is a state in which only the control unit 11, which is the host control means, is activated, and in this state, no signal processing of itself, for example, a data input / output process with the outside cannot be performed. Only power-on key signal input can be recognized.

Therefore, the standby state of the conventional optical disc reproducing apparatus is not suitable for the disc rental system described in the present invention. Therefore, in the present invention, a new method for transmitting a signal from the outside even in a power-off state where the user does not use the system is possible. It is intended to implement a form of system standby.

Accordingly, an object of the present invention is to provide a standby operation control method and apparatus for an optical disc reproducing apparatus that can receive a signal from the outside even when the system is not operated.

Another object of the present invention is to provide a standby operation control method and apparatus for an optical disc reproducing apparatus capable of receiving a signal from the outside with a minimum power supply in a state where the system is not operated.

In the standby operation control method of the optical disk reproducing apparatus according to the present invention for achieving the above object, in the optical disk reproducing apparatus capable of transmitting and receiving data with the outside, when a power-off signal is received, the external supply to each component constituting the reproducing apparatus And a standby mode step of supplying a minimum power to only components required to perform an operation by receiving a power-on signal and a request for data transmission / reception with the outside.

A standby operation control apparatus for an optical disc reproducing apparatus according to the present invention for achieving the above object includes a data transceiver for performing data transmission and reception with an external device, a memory for storing the data transmitted and received, and data of the data transmission / reception unit and memory. And a controller for controlling an input / output operation, and a battery power supply for supplying power to the data transceiver, a memory, and a controller in a power-off state.

The present invention utilizes a path connecting an optical disc reproducing apparatus owned by a supplier station and a consumer through a public communication network. When the disc reproducing operation of the optical disc reproducing apparatus is not performed, only a minimum device capable of inputting a signal through a public communication network is operated, and all other devices are deactivated.

Then, at a time when the consumer does not feel inconvenience in the transmission time, any number of signals can be transmitted from the supplier station to the consumer's optical disc reproducing apparatus through the public communication network. In this case, the transmitted signal includes advertisement data.

The consumer's optical disc reproducing apparatus receives data supplied from a supplier station while the system is in the off state or the disc is not being reproduced, and displays the received data when the consumer operates the optical disc reproducing apparatus. Will automatically serve ads to

Therefore, when there is a data transfer request from the supplier station to the consumer's optical disc reproducing apparatus, the consumer's optical disc reproducing apparatus must maintain a state capable of receiving data according to the state of the system. This state is called a standby state in the present invention.

Hereinafter, a standby operation control method and apparatus for an optical disc reproducing apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

The standby mode of the optical disc reproducing apparatus described in the present invention is suitable for a system newly implemented in the next generation. Therefore, a brief description of the proposed system prior to the description of the present invention.

The new system produces a large volume of disks, each with a unique identification number unique to each disk, providing the disks to consumers at a low price, and then post-management of the disks sold over the network, such as It allows you to manage the playing time, the player, the playing cost, and so on.

Therefore, the system eliminates the inconvenience of returning the disk from the consumer's point of view, and also allows the disk rental time to be calculated from the point of time desired by the consumer, and minimizes the cost of purchasing the disk.

In addition, in view of the disciple who produced the disc, the system prevents the borrowed disc from being illegally copied and eliminates the difficulty of not being recovered after the rental time has elapsed, and is particularly popular among consumers. Disc is a system that has been proposed to accommodate both consumer and producer's needs in various ways, such as more profits compared to the conventional.

In other words, the newly proposed disk rental system has a signal transmission path in which the supplier station and the consumer's optical disk player are connected to each other by a network for the post-management of the sold DVD.

Therefore, on the provider station side, it is possible to transmit advertisement data about newly released disks or warning and notification data for follow-up management to consumers by using a signal transmission path through the network. It may be desirable to do so in a time zone that does not cause inconvenience to users.

2 is a block diagram showing an optical disk reproducing apparatus that can be controlled through a network according to the present invention.

The structure of the optical disc reproducing apparatus includes a disc 31 storing various types of data, an optical pickup device 35 for reading data from the disc 31, converting the data into an electrical signal, and outputting the same; And an analog signal processor 43 for outputting after performing analog signal processing such as signal compensation and filtering of the analog signal outputted at 35.

When it is determined that the mounted disk is a disk capable of remote control, signal processing such as digitization and error correction is performed on the unique identification information of the disk 31 read from the optical pickup device 35, and the unique identification information of each disk is performed. And a reproducing section 63 for transmitting the recognized unique identification information to an external business server and receiving a regeneration authorization control signal accordingly.

A digital signal processor (DSP) 37 for inputting data output from the analog signal processor 43, converting it into a digital signal, demodulating the signal, and outputting the signal after signal processing such as error correction, and the optical pickup device 35; Servo control unit 51 for controlling tracking and focusing of the controller, an on-screen display generator 53 for generating a signal necessary for the on-screen display, and an output processor 39 for output processing up to display. do.

Then, a command from the user is received through the key input unit 55 to perform control accordingly, and necessary system control such as the servo control unit 43, the DSP 37, the reproduction applying unit 63, and the output processing unit 39 is performed. It has a component such as a control unit 41 for performing the. In particular, the error correcting unit in the DSP 37 requires a separate block for performing ECC processing by dividing the general DVD data and the data read from the remote control disc under the control of the control unit 41. Therefore, the optical disc reproducing apparatus according to the present invention is a decryption circuit section 57 for inputting ECC processed data and decrypting the encrypted video data for illegal copying according to the output from the reproduction authoring section 63. Is further included in comparison with a general optical disc reproducing apparatus.

After inputting and rectifying the AC power from the outside, the power supply unit 61 converts the DC power into the required size and supplies the circuit power to each circuit unit. The power output control of the power supply unit 61 is performed by the controller 41. This is done when a power-on key signal is recognized.

In addition, in order to achieve a standby operation according to the present invention, even in a power-off state, some components need a configuration for achieving a standby state that can be operated at any time by receiving power.

Therefore, the key input unit 55 is a standby state by the built-in battery power supply unit 57, the control unit 41 which is a host control means is a power-on key output from the key input unit 55 by the battery power supply unit 59 The signal is ready for recognition at any time. In addition, the battery reproducing unit 63 is also able to transmit and receive data even when the system is powered off by the battery power supply unit 65 through the business server and the public communication network 200.

The battery power supply units 59 and 65 receive power from the power supply unit 61 when the power is on, and charge the battery power supply units 59 and 65, and discharge the charged power when the power supply unit 61 is disconnected from the power supply unit 61. .

That is, according to this configuration, before the power-on signal is input through the key input unit 55, only the control unit 41, the key input unit 55, and the reproducing application unit 63 can operate at any time by the battery power source. Becomes In this standby state, the reproduction authorizing unit 63 transmits and receives data with the business server through the public communication network 200.

When the power-on signal is input to the controller 41 through the key input unit 55, the system is operated while power is supplied from the power supply unit 61 to each circuit unit under the control of the controller 41, and then the remote control. Playback of the DVD 31 is possible.

FIG. 3 shows a detailed configuration of the reproducing unit shown in FIG.

Post-management of each DVD reproduced from the plurality of optical disc reproducing apparatuses, that is, the permission of reproducing the sold disc, the reproduction time, connected to the reproduction authoring unit 63 of the plurality of optical disc reproducing apparatuses through the public communication network 200 There is a business server that performs management according to the player, the player, the regeneration cost, and the like. Therefore, the server should basically include a modem for enabling connection with a plurality of optical disc reproducing apparatuses through the public communication network 200, a processing apparatus and a storage apparatus for performing and processing various operations proposed by the present invention. will be.

In addition, the public communication network 200 may use a telephone communication network that is currently widely used as an information communication network, or may use a dedicated communication network. Such a communication network need not be limited to a wired communication network, and may be configured using a wireless communication network that is gradually being spread.

The reproduction applicator 63 of the optical disc reproducing apparatus stores a modem 73 connected to the server via the public communication network 200 to directly transmit and receive data, and data transmitted and received from the modem 73. And a data processor 69 which performs predetermined signal processing such as modulation / demodulation, error correction and amplification of data output from the memory 71, and enables high-speed DVD data input / output. The controller 73 performs control of the modem 73, the memory 71, and the data processor 69, and simultaneously transmits the data stored in the memory 71 through data transmission with the controller 41, which is a host control means. Sub-control unit 67 for performing the control.

The reproduction applying unit 63 having such a configuration is intended to perform data transmission from the server through the public communication network 200 by receiving power from the battery power supply unit 65 even when the user turns off the optical disc reproducing apparatus. At this time, a standby state (STAND-BY) state that can receive data at any time.

In addition, when the mounted disc 31 is determined to be a DVD for remote control, the reproducing unit 63 digitizes the unique identification information of the disc 31 read from the optical pickup device 35 and processes the signal such as error correction. And recognize the unique identification information of each disc, and transmit the recognized unique identification information to an external business server and receive a reproduction authorization control signal accordingly.

Next, the standby operation control method and the operation of the apparatus of the optical disk reproducing apparatus of the present invention having the above-described configuration will be described in detail.

4 shows an operation process when entering the standby mode in the optical disc reproducing apparatus according to the present invention.

After the user uses the system, if the power-off signal is applied to the control unit 41 through the key input unit 55 (step 401), the control unit 41 recognizes the power-off signal and then supplies it to the power supply unit 61. The control signal to cut off the main power is output (step 402). Then, while the power supply is cut off from the power supply 61, the power applied to each circuit part of the system is cut off.

Then, the discharge power of the battery power supply unit 59 is supplied to the control unit 41, and the discharge power of the battery power supply unit 65 is also supplied to the regeneration applying unit 63, so that the control unit 41 and the regeneration applying unit ( 63 is in a standby state where the operation can be performed at any time as in the power-on state (step 403).

On the other hand, when it is not in the power-off state in step 401, in the state that the user does not directly apply the power off signal, that is, the power off signal through the key input unit 55 is not recognized by the controller 41, The control unit 41 determines whether the signal processing is performed according to the reproduction of the disc 31 and the additional process thereof (step 405).

If signal processing of a certain function according to reproduction of the disc 31 is performed in step 405, signal processing according to the present function execution is continued (step 413).

However, when no signal processing is performed in step 405, the controller 41 determines whether a predetermined time has elapsed since the last signal processing is performed by a built-in timer (step 407).

At this time, when included within the set time, the current state (power being supplied from the power supply unit 61 to each circuit unit) is continuously maintained, and after the set time, any further operation is performed in the state of being turned on by the user. It is judged that no state is performed.

In this state, the control unit 41 itself applies a control command to cut off power to the power supply unit 61, and accordingly, the power supply unit 61 stops supplying power to each circuit unit (step 409). Then, the control unit 41 and the reproducing application unit 63 automatically supply power from the battery power supply units 59 and 65, and a standby state for operating the system according to the next user's command is obtained (step 411). .

Next, FIG. 5 is a flowchart illustrating an operation process in the standby mode of the optical disc reproducing apparatus according to the present invention.

When the disc is not reproduced in the optical disc reproducing apparatus, that is, when the user powers off the optical disc reproducing apparatus, the player configuration necessary for reproducing the disc except for the control unit 41 and the reproducing application unit 63 is supplied. This is a blocked state.

In other words, the regeneration authorization unit 63 that communicates with the external business server is in a state in which power is supplied by the battery power supply unit 65 even in this state. In other words, it is a standby state in which data can be transmitted and received. Therefore, when the sub-control unit 67 is in the standby mode state, the sub-control unit 67 maintains the state capable of self-control by checking whether the power-off state (step 501).

Therefore, when a business server needs to transmit advertisement data on a newly released disc or data on a part to be informed to the user (for example, playing time, playing cost, etc.), the modem of a specific optical disc playing apparatus to be transmitted is required. Enters the process of checking the state that can transmit and receive data with (73).

That is, the sub-control unit 67 receives data from the modem 73 asking whether the signal can be transmitted from the outside (step 503), and the state in which the current system is in use by the user due to playing of the disc. The acknowledgment is confirmed by close connection with the control unit 41, and when receiving a signal indicating that the system is not in use, the controller 41 outputs an external signal reception possible signal (step 505).

If it is determined in step 505 that the signal can be transmitted and received to the outside, the sub-control unit 67 controls the modem 73 and the memory 71 to prepare a state capable of receiving external data, and the public communication network In step 507, the server establishes a connection with the server to which data is to be transmitted. At this time, the connection between the server and any optical disc reproducing apparatus may be performed one-to-one, or simultaneously with a plurality of optical disc reproducing apparatuses in one-to-many fashion.

The connection between the server and the modem 73 of the specific optical disc reproducing apparatus in step 507 by using the time when the user does not use the player is performed even if a relatively large amount of data is transmitted from the server at one time. In order to proceed without causing inconvenience such as the transmission time to the server, the server uses this time zone to transmit the desired amount of data.

When data transmission and reception between the modem 73 and the server of the specific optical disc reproducing apparatus is enabled in this manner, the server transmits the data to be transmitted through the public communication network 200. The modem 73 receives data transmitted from the server (step 509).

The data received through the modem 73 is stored in the memory 71 under the control of the sub-control unit 67. The memory 71 has a predetermined size or more, is capable of sufficiently storing data transmitted from the server, and also enables rewriting to overwrite data when the amount of data stored in the memory reaches a limit. (Step 511). In this process, the data stored in the memory 71 is stored until the user displays the power by turning on the optical disk player.

That is, in the standby mode by the power-off, data input from the outside continues to be stored in the memory 71, and the data stored in the memory 71 is stored in the following process when the user turns on the optical disc reproducing apparatus. Is displayed.

First, when the user applies the power on signal to the control unit 41 through the key input unit 55, the control unit 41 recognizes a power on command, and supplies a control signal to supply power to each circuit unit to the power supply unit 61. Outputs Thereafter, power is applied to all system configurations for reproducing the disc from the power supply unit 61, and a preparation step for reproducing the disc is performed, so that the system enters the mode for reproducing the system in the standby mode.

In this way, immediately after the system is started, the sub-control unit 67 checks whether or not the reception data can be output to the control unit 41 during the set-up time required in the preparation step for regeneration. Immediately after is applied, the output of the data stored in the memory 71 is controlled. In this case, the data output may be made of advertisement data or notification, warning data, etc. for the new disk.

The data output from the reproduction applying unit 63 is outputted from the memory 71 under the control of the sub-control unit 67, and this data is input to the data processor 69 to demodulate and transmit digital data. After signal processing such as error correction is generated, the signal is applied to the output processor 39 through the decryption circuit 57. Data input to the output processor 39 performs predetermined signal processing for display on the display unit, and then displays the data.

Therefore, after the system is turned on, while the set-up process of the predetermined time is required, the output processing unit 39 can output the screen of several frames provided by the server, and thus outputs an advertisement for the new disk at this time. If so, the user can see the latest advertisement for the new disc instead of watching the display on a typical blue screen.

Immediately after the system is ready for disc playback, the sub-controller 67 suppresses data output from the data processor 69 at the request of the controller 41, thereby delaying the playback of the disc to be played by the user. This can eliminate the possibility of a data collision.

On the other hand, the inquiry whether the sub-control unit 67 according to the output state of the reception data to the control unit 41 is a process for receiving the use of the output processing unit 39 and the display unit under the control of the control unit 41.

Therefore, as described above, the controller 41 may allow the sub-control unit 67 to output the received data for a required time according to the set-up process immediately after the system is started, and also according to a preset program. The output may be allowed in predetermined units during playback.

In addition, in the case of a DVD which enables storing of a plurality of programs, the sub-control unit 67 may allow the output of the received data immediately after the completion of playback of each program and before the next program playback. When the user request is generated, the control unit 41 may request the output of the received data to the sub-control unit 67. That is, the reproduction of the data received from the server under the control of the sub-control unit 67 may be possible in any form within a range that does not cause a specific problem caused by the reproduction of the DVD.

Thereafter, when the optical disc reproducing apparatus normally starts reproducing the disc, the reproducing section 63 inputs a specific unique number read from the disc from the data processor 69 and performs modulation to a signal capable of data transmission. It stores in the memory 71. And it transmits to the server connected to the outside via the modem (73).

The server, which receives the reproduction permission request signal for the specific disk from the specific optical disk playback apparatus through the public communication network 200, checks the unique number of the disk. If the second payment request has not been made or the first rental period has elapsed, a message is sent to the player, and if the payment is not made, the player is prohibited from playing and there is no problem. In this case, playback is applied. The server has a database of title information, billing history, playback history, user profile information, etc. for the corresponding unique number.

On the other hand, in some cases, when a user purchases a particular disk and wants to rent or own it permanently, the user may input such a command through the player's key input unit 55. When such a purchase command is transmitted to the server, the server may grasp the unique number of the disc and store it in the memory device, and then, if a playback request from the player comes in, the server may process the video to be viewed indefinitely.

Through this process, the business server checks the validity according to the reproduction permission for the unique identification information (BCA information) of the disc authorized through the modem, and then transmits a control signal according to the reproduction permission or impossibility.

When the reproduction permission signal is input from the business server, the reproduction authorization unit 63 transmits a disc reproduction permission signal to the control unit 41, and then the control unit 41 reproduces normal data of the title stored in the remotely controllable disc. Perform control for Therefore, the connection between the modem 73 and the server is only disconnected and disconnected until the result of the reproduction permission is received in the state where the disc is played, so that the communication load is not a problem even when using a communication network such as a public telephone network.

After receiving the reproduction permission signal from the server, the data reproduced from the disc is decoded after signal processing such as amplification, signal compensation, error correction, and decoding are performed in the analog signal processing unit 43 and the digital signal processing unit 37. In order to prevent illegal duplication of the remote rental video data, the circuit unit 57 decrypts the output signal to the output processor 39 according to the control signal of the playback authoring unit 63. The output processing unit 39 performs a predetermined signal processing until data is displayed on the display unit, and outputs the data, thereby enabling users to view the data displayed on the display unit.

As described above, in the standby mode of the optical disc reproducing apparatus according to the present invention, battery power is supplied to the reproducing application section 63 in the power-off state to maintain the standby state. When a data transmission request is generated from the outside, the reproduction authoring unit 63 itself receives data and stores it in the memory 71. That is, in the illustrated form, all the configurations of the reproducing and applying section 63 are in a standby state in which power is supplied even when the power is turned off.

However, the standby mode of the optical disc reproducing apparatus according to the present invention is not limited to the above configuration, and may be in any form as long as it can receive data when there is a data transmission request from the outside.

For example, in the present invention, the control unit 41, which is a host control unit for performing overall control of the optical disc reproducing apparatus, and the sub-control unit 67 in the reproduction authoring unit 63 are configured as separate processors. It may be possible to control all of the systems by configuring them as one. In other words, it is also possible to perform a control for reproducing a disk in the operating state of the system, and to perform a control for performing data transmission / reception with the outside in a standby mode in one processor.

In addition, even in the reproduction applying unit 63, only a very minimum signal processing means may be kept in the standby state. For example, only the modem 73 and the sub-control unit 67 are in a state where power is supplied, and when a data transmission request is generated from the outside, power is supplied to the memory 71 under the control of the sub-control unit 67. While this is done, it is possible to store the received data.

As described above, the standby operation control method and apparatus of the optical disc reproducing apparatus according to the present invention maintain a standby state by supplying power to a minimum device capable of receiving data from the outside without using the system. . In this standby state, the latest advertisement data, which could not be achieved by the conventional optical disc playback apparatus, can be continuously and individually and infinitely provided to consumers, so that the cost of the separate advertisement work on the producer side of the new disc is required. And it can bring the advantage of not having to spend time.

In addition, the present invention has the advantage that consumers can continue to be provided with the latest advertising information without additional efforts.

Therefore, the standby operation control method and apparatus of the optical disk reproducing apparatus according to the present invention have the advantage of being able to accommodate the needs of both the consumer side using the system and the supplier side to provide up-to-date information.
