CD / BSI multi device with CD auto play function

The present invention relates to a cd / vsial composite device having a cd auto play function, which can eliminate the inconvenience and inconvenience in the operation process during the playback of the cd disc in the composite device.

CD / BSI devices are designed to provide a compatible environment for use of magnetic tape-type video tapes or optical disk-type CD disks, which are storage media for storing video pros, and from various types of video / audio sources. It is designed to accept signals from

1 shows a system circuit block diagram of a typical form of a CD / VSI composite device of this type.

Here, the CD / VSI composite device is composed of a CD drive system and a BC drive system. First, the BC drive system inputs a key input from the remote controller transmitter 126 or a key input from the key matrix 121, respectively. A microcomputer 120 for receiving, a tuner 145 for tuning the corresponding channel in the broadcast signal received from the antenna 146, a phase lock loop unit 144 for providing a tuning control signal to the tuner 145, Digitron 148 for displaying various functions, clocks, and the like, an OSD unit 149 for displaying OSD contents on the screen, and an RF module connected to an output terminal of the ODS unit 149 to modulate radio frequency And a modulator 150.

In addition, the system includes a monitor 151 connected to an output terminal of the RF modulator 150 and outputting a video signal, and a synchronization to separate the synchronization signal from the video input generated by the system and provide it to the OS 149. The separating part 152, the deck part 128 which performs a tape reproducing / recording operation, the servo part 129 which drive-controls this deck part 128, etc. are comprised.

The CD drive system includes a CD drive unit 133 for driving the mounted CD disc, a motor 132 for operating the CD drive unit 133, a pickup unit for picking up a predetermined signal from the disc being driven, and the pickup unit. The actuator 138 to drive, the RF unit 136 for detecting the RF signal from the pickup unit, the focus / tracking unit 137 for controlling the actuator 138, and the CD-side microcomputer 130 for controlling the CD ), Etc. are provided.

In addition, the system includes a motor driver 131 for controlling the motor 132 for driving the CD, a digital signal processor 139, a die converter 140 for converting a digital signal into an analog signal, and a signal amplifier ( 141, the left / right speakers 142 and 143, and the CD driver 133 detects a CD driving state and transmits predetermined detection information to the microcomputer 120 on the VSI side. ), Etc.

Looking at the operation of the conventional CD / BCD system, the VSI drive system can perform the video playback operation to watch the playback contents of the video tape reproduced from the VSI unit through the monitor 151, In the CD drive system, when the CD disc is played back, the VSI drive system is stopped and the monitor 151 can watch the video program on the CD side.

On the other hand, even in the case of the audio pro, the audio pro played on the CD side can listen to the CD music pro played on the CD through the left and right speakers 142 and 143 constituted by a set.

In addition, in the conventional CD / VSI composite device system configured as described above, a method of reproducing the contents of a CD disc includes: opening the CD cover → opening the CD tray → opening the CD disc in the CD tray in order to reproduce the CD. It was achieved by mounting → closing the CD cover → pressing the pause key → pressing the play key on the CD.

As described above, the process of playing a CD disc in a CD / VSI composite device requires the user to perform a series of operations and key manipulations in several stages in the step of instructing the system to play a CD as described above. It was very cumbersome and inconvenient when using the system.

An object of the present invention has been developed to improve such a conventional problem, when a user wants to play a CD disk in the CD / V-CD system, the user opens the cover of the CD without performing the cumbersome multi-step operation. By simply placing a CD disc in the tray, the system automatically handles all subsequent steps, minimizing user intervention, making it easier to play CDs in a CD / VSI system.

In order to achieve the above object, the system includes a key input unit including a time setting key for invoking an OSD program for setting an automatic CD playback time, and an OSD program for setting an automatic playback time in the key input unit. A microcomputer that registers the set time from the memory into the memory and automatically enters the play mode at the set time when there is an automatic play key input from the key input unit, and creates an automatic play time setting menu screen under the control of this microcomputer. CD automatic playback including a CD, a CD for delivering the CD closing and reproducing operation key data provided from the microcomputer to the CD driving unit, and a CD for performing the playback operation after the CD is closed under the control of the CD. Characteristic features of CD / BSI devices with functions will be.

Hereinafter, more specific features of the present invention will be understood by describing the same in detail with the accompanying drawings.

That is, FIG. 2 shows a system circuit block diagram of a CD / VSI composite device having a CD auto play function according to the present invention.

In this case, the system includes a key input unit 11 including a time setting key for invoking an OSD program for setting an automatic CD playing time, and a time set from the OSD program for setting an automatic playing time in the key input unit 11. Is registered in the memory 14 and the automatic playback key input of the key input section 11 controls the microcomputer 12 to automatically enter the playback mode at a set time, and the automatic playback under the control of the microcomputer 12. An OS 13 for generating a time setting menu screen, an SSP 15 for transmitting CD closing and reproducing operation key data provided from the microcomputer 12 to the CD drive unit 16, and the SSP ( And a CD unit 16 for performing a playback operation after closing the CD under the control of 15).

According to the present invention, when the user plays the CD using the CD / VSI composite device as described above, the CD is opened.The CD cover is opened from the CD drive unit 16 as shown in FIG. You can execute system playback by pressing CD → Closing CD tray → pressing PAUSE key → pressing CD playback key.

At this time, when the user automatically plays the key input unit 11, when the play key is pressed, the operation of closing the CD tray → pressing the pause key → pressing the play key of the CD can be omitted.

That is, when the user presses the time setting key of the key input unit 11, the microcomputer 12 provides the automatic play time setting menu screen through the OS 13 and the user automatically plays according to the time setting method displayed on the menu. You can set the time.

The automatic playback time value set through the OS 13 is registered in the memory 14 and serves as a default value in system operation after the time value is not changed or modified.

On the other hand, when there is a play key input of the key input unit 11 after setting the automatic playback time value through the operation of the microcomputer 12 as described above, the microcomputer 12 is based on the automatic playback time SSP ( 15, the CD closing and reproducing command data are provided, and the SSP 15 enters the reproducing mode continuously with the automatic closing of the CD tray of the CD driving unit 16 to drive the disc.

Therefore, the user can automatically perform all the operations reduced in a predetermined time without the need for the troublesome operations and operations that occur during CD playback.

The present invention, when playing the contents of the CD disk in the CD / BD composite device system, unlike the prior art, the user does not bother with multi-step operation and multiple key operations, with only one key operation with the automatic playback time setting. It is possible to improve the usability of such a system by enabling CD playback.
