BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display system, and more particularly, to a display system that expands the functions of a display device in a general sense and increases convenience of use. More specifically, the present invention relates to a display system that improves the usability and utilization of a display device by improving a DVR (Digital Video Record) device in which video / audio signals received from the display device are stored.

A display device in a general sense is a device that reproduces a video / audio signal received through an air wave or a wired cable in a form that a user can watch. Such display devices have gone through the era of black and white television and color television, and now have been able to watch digital broadcasting. In recent years, not only the intrinsic function of a display device that reproduces a broadcast signal currently being transmitted, but also a DVR (Digital Video Record) device that stores a broadcast signal in advance in the form of a digital signal at the present time and plays it when a viewer desires it. It is used. The DVR device is a device proposed by TIVO, Inc. in the United States, and since its use is well known, a detailed description thereof will be omitted.

However, since the DVR device is used as a set-top semi-permanently attached to the display device, the DVR device is used exclusively for one display device. In other words, a DVR device connected to any one display device always receives, stores and plays only broadcast signals received by the display device as an accessory of the display device. Therefore, the user can watch the broadcast signal stored in the DVR device only by using the display device that the user always watches.

In addition, the conventional DVR device has a problem that it is not easy to simplify the display system because of the large size, especially in the case of the display device used on the wall, such as a wall-mounted display device is more cumbersome and uncomfortable for the user There is a problem that causes. In addition to this, the person who purchased the display device has to purchase a set-top separately, which increases the cost.

In order to improve this problem, a display device, which is recently introduced, has a display device having a hard disk built therein. However, even in the case of a display device with a built-in hard disk, it is impossible to move the hard disk, which causes a lot of inconvenience to the user.

The present invention improves the mobility for convenient use of the DVR device, can be used universally for a large number of display devices, and suggests an external device that is easy to connect to the display device body, thereby increasing convenience of use. We propose a display system.

In addition, the present invention proposes a display system in which an external device separated from the main body of a display device can be widely used for various purposes, thereby improving the efficient use and accessibility of data.

In addition, the present invention proposes a display system that can be easily separated from the display device main body and an external device, and that various types of hard disks can be mounted and used in a single device.

Display system according to the present invention is a display device; A bay having an insertion hole formed on an outer surface of the display device; An external device inserted into the bay and mounted therein, and having a hard disk embedded therein; And two or more connectors formed on the external device to allow the hard disk to be connected.

According to another aspect of the present invention, a display system includes a display device; A bay formed in the display device; And an external device inserted into the bay and mounted with a hard disk, and after the external device is inserted into the bay for a predetermined distance, the external device is automatically inserted into the bay to access the bay. It is characterized by being connected to the block.

The proposed display system allows for convenient viewing of broadcasts, unlimited use of external devices, increased viewer satisfaction, increased data availability, and convenient handling of hard disks. There is this.

Hereinafter, with reference to the drawings will be described in detail a specific embodiment of the present invention. However, the spirit of the present invention is not limited to the proposed embodiment, and those skilled in the art can obtain other embodiments easily added, changed, deleted, and added to other embodiments that fall within the scope of the same idea.

And a bay 2 formed on one side of the exterior of the display device 1, and an external device 3 inserted into or removed from the bay 2. The display device 1 has a high utility value because it is a flat panel display device used as a wall-mounted device, since the wall-mounted display device is used in a form mounted on a wall, and thus it is difficult to install a separate set-top.

In detail, the bay 2 is a portion recessed inwardly from the main body exterior of the display device 1, and the external device 3 is inserted through an opening formed outside the bay 2. Withdrawn. The word "vear" is a term widely used in various industries, and in the field of information and telecommunications, it refers to the "folding of panels, switches, units, or self-assembled parts of a device into ladders and lockers of a certain length." Has meaning. In the present invention, the recessed portion is formed inward from the outer surface of the display device 1, and the portion that allows the external device 3 to be easily inserted or detached into the recessed portion. It is easy to think of, by pushing the external device 3 into or out of the bay 2 exposed to the outside of the display device 1 while the external device 3 is held by the user. Naturally, it is foreseeable that the convenience of the user is enhanced by causing the device 3 to be connected or disconnected.

In addition, the external device 3 is preferably a device in which a storage device exemplified as a hard disk is embedded, and a broadcast signal received from the display device is received by the external device 3 and stored in the external device 3. The signal stored in the external device 3 is transmitted to the display device 1 to be output as an image / audio by the display device 1. The external device 3 is electrically connected to the display device 1 by a predetermined connection part while being inserted into the bay 2 and seated therein.

The use mode of the display system according to the present invention will be described separately in each case. First, when the user inserts the external device 3 into the bay 2, the external device 3 can be operated as a general DVR device. In detail, the external device 3 has a built-in hard disk as a storage device. The hard disk stores the broadcast signal received from the display device 1 in real time. The stored information is later sent to the display device 1 when there is a call from the user, and is processed into video / audio information on the display device and output. Since this is used similar to a general DVR device, it can be called DVR mode.

In another embodiment, since the external device 3 is free to take out with respect to the display device 1, the external device 3 is drawn out in a state in which a broadcast signal is stored in the external device 3, and the external device 3 is mounted on another display device 1 so as to be mounted on another display device. You can also watch the broadcast through. This mode can be called a move mode.

As described, according to the display system according to the present invention, the user can conveniently use the display system of the present invention because the external device on which the hard disk is mounted can be freely taken out. In addition, since the hard disk is not provided as a separate set-top, it can be conveniently applied to a wall-mounted display device and can be used.

2 and 3 are block diagrams of a display system according to the present invention. FIG. 2 is a block diagram of a display device, and FIG. 3 is a block diagram illustrating a configuration of a connection unit between a display device and an external device in more detail.

Referring to FIG. 2, the display device 1 of the present invention includes a digital receiver for receiving a digital broadcast signal, an analog receiver for transmitting and receiving an analog broadcast signal, a controller for controlling the display system as a whole, and an image / audio signal. It includes an output unit, and the external device connecting portion in charge of the connection control with the external device (3).

The configuration and operation of each part described above will be described in more detail. However, the central processing unit (CPU) 108 provided in the present invention forms a central portion for each control of the display device, and sends control signals to each component, but omits the drawing of the control line to prevent congestion in the drawings. The following description will focus on the flow of broadcast signals.

First, the digital receiver will be described in detail. As a digital signal transmitted by satellite wave, terrestrial wave, or cable transmission method, a broadcast signal of a specific channel is received through the digital tuner 101. The received signal of a particular channel is converted into a digital bit stream at the demodulator 102. In the digital bit stream, a video stream, an audio stream, and a data stream are mixed into a plurality of packets. Therefore, the de-multiplexer 103 identifies the ID of each packet, separates the image, sound, and data, and sends them to each decoder. The demultiplexer 103 may be operated in a manner defined by MPEG 2 or MPEG 4. The MPEG 2 or MPEG 4 is a well known scheme. According to the MPEG standard, the video stream is decoded in the video decoder 104 and then imaged in the graphics processor 105, the sound stream is decoded in the audio decoder 106, and the data stream is decoded by the data decoder 107. Decoded.

The analog receiver is a transmission method mainly comprising the current airwave broadcasting. First, a broadcast signal of a specific frequency channel is received by the analog tuner 120. Since the signal received by the analog tuner 120 is a signal used for the operation of the display device, it does not need to go through a separate decoding procedure. The video signal is processed by the appropriate video processor 118 and the audio processor 119 according to the scan rate, the frame number, etc. of the video signal according to the form of the broadcast signal, and then displayed on the screen 116 and the speaker 117 as video / audio. .

The output unit is configured to output a broadcast signal as an image and sound that can be recognized by the viewer, an image processor 114 for processing the image / sound signal decoded by the decoders 104, 106 and 107 and sound A processor 115, an image processor 118 and an audio processor 119 that process video / audio of an analog signal are included. In addition, the screen 116 and the speaker 117 for outputting the image and sound in a form that can be recognized by the viewer is included. As for the image processor 114, 118 and the sound processor 115, 119, the image processor 114, 118 is described as being provided in plural, but a single processor regardless of analog signals or digital signals. Is also processed by the acoustic processor 115, 119.

The controller includes a central processing unit (CPU) 108 that is responsible for the overall operation of the display device 1. The central processing unit 108 is a central part of the operation of the display device such as initializing the device, monitoring and managing interrupts of each component, processing input signals of a user, executing programs, and processing data or commands. In addition, a RAM 111 and a ROM 110 are stored as storage devices for storing various kinds of information necessary for the operation of the CPU 108. The ROM 110 stores information such that memory is maintained even when the display device is turned off, such as control information and boot information, and the RAM 111 is temporarily stored during operation of the central processing unit 108. Function as a device.

In addition, the central processing unit 108 is connected to the user interface 109, the user interface 109 receives a user's command and delivers it to the central processing unit 108. In this case, when the signal input through the user interface 109 is a transmission signal from a display device transmitted through a return path, the signal is modulated by the central processing unit 108. It is modulated by and transmitted through the digital tuner 101. In addition, the bus 113 is defined so that data exchange between components inside the display device is performed.

The external device connection unit is provided with a device interface 122 which is in charge of a signal transmitted from the display device, and the device 123 which is an external device is connected by the device interface 122.

In detail, the signal transmitted to the external device 123 through the device interface 122 may be data received through the digital receiver or data received through the analog receiver.

In addition, the signal transmitted through the device interface 122 may be transmitted as a multimedia data signal in the standard of USB, IEEE 1394 suitable for large capacity signal transmission. In addition, the method is a two-way communication is performed by the compression method of the digital data, HDMI (High definition Multimedia Interface) method in order to directly transmit and receive analog signals between the display device 1 and the external device (3) It is also possible for communication to be performed by. The HDMI is an interface capable of transmitting an uncompressed analog signal at high speed, and may be preferably applied when transmitting a broadcast signal received by the analog tuner 120. The E-IDE method, the S-ATA method, the P-ATA method, and the SCSI method are used as interface interfaces capable of directly exchanging data between the hard disk and the display device 1 embedded in the external device 3. The hard disk interface method may be used. Such a communication method will vary depending on the specifications supported by the device interface 122 and the external device 3. However, when the analog signal received from the analog tuner 120 is converted into a digital signal and transmitted as a digital signal, it may be easily assumed that the encoder 121 is further used as a separate component.

On the other hand, the present invention proposes a display system comprising an external device (3) having at least a hard disk embedded therein and detachable, and a display device (1) for exchanging data with the external device (3) and watching a broadcast signal. Doing. By such a system, there is an advantage that the convenience of a user watching a broadcast is enhanced, and an aspect of viewing a display device may be more diversified.

The structure of the bay will be described with reference to FIGS. 7 to 10. The bay case 201 forming the exterior of the bay 2 is provided in the shape of a rectangular parallelepiped, and one side edge thereof is chamfered so that the insertion direction of the bay case 201 is accurately guided so that the bay side position guide 204 is provided. It is formed to be aligned with the device side position guide (see 307 of Fig. 4) so that the external device (3) can be easily inserted. In addition, a bottom plate 210 is further formed on the bottom surface of the bay case 201 as a separate plate-like structure.

The external device 3 and the bay 2 having the above-described approximate structure will be described in detail in the order of operation in which the external device 3 is inserted.

First, when the external device 3 is inserted, the door 202 formed at the front end of the bay case 201 is pushed up, and once the door 202 is pushed up, the bay case is removed until the external device 3 is removed. It is supported by the external device 3 inside the upper surface of 201. In this state, when the external device 3 enters a predetermined depth or more, the insertion sensing protrusion 229 is pushed slightly. Since the insertion sensing protrusion 229 is formed in the third link 222, the third link ( 222) is also pushed by a certain length.

When the third link 222 is pushed, the second link 221 and the first link 220 connected thereto are also pushed, so that the insert groove 251 formed on the outer surface of the first link 220 and its The on / off state of the switching terminal of the micro switch 250 is changed by the mutual operation of the micro switch 250 caught by the insert groove 251. The on / off change of the micro switch 250 is transmitted to the control unit of the display device 1 to drive the motor 226, so that the bay 2 automatically pulls the external device 3 inwards. The sequence of starts.

When the motor 226 is rotated, the rotational speed is changed via the gear train 227, and eventually, the motor 226 is transmitted to the first link 220 to rotate the first link. The rotational force of the first link 220 acts as a pulling force of the second link 221, and the second link 221 is hingedly connected to the third link 222 to pull the third link 222. . The third link 222 is guided by a slit 211 formed in the bottom plate 210 and a guide protrusion 228 protruding downward from the third link 222 and inserted into the slit 211.

The lamp 212 is lifted up. In addition, when the fourth link 223 is moved rearward by a predetermined distance by riding the lamp 212, the push protrusion 225 formed at the end of the fourth link 223 is the lower surface of the external device case 301. The locking groove 320 is to be fitted. In this state, if the fourth link 223 continues to move backward, the external device 3 continues to move backward.

After the external device 3 is moved backwards by a predetermined distance or more, an adjustment pin 240 formed in the bay so as to be inserted into the adjustment hole is formed in the corresponding surface of the external device 3. Is fitted on.
In detail, the alignment unit including the adjustment pin 240 and the adjustment hole 308 is connected to the connection block 260 having an input / output terminal 309 formed on the rear surface of the external device 3 in the bay case. The movement of the external device is guided so as to be electrically connected. In this case, since the end of the contact pin 261 placed inside the connection block 260 is bent at a predetermined angle, the terminal of the input / output terminal 309 may be reliably contacted with the contact pin 261.

When the series of connection processes as described above is completed, the electrical connection is also performed by the hot plug function between the external device and the display device when the mechanical connection is completed. 11 and 12 show the structure of the bay case 201 in which such a process is performed, and thus the connection between the two is completed.

On the contrary, when the external device case 301 is described to be drawn out, the first operation of drawing the external device 3 is indicated by the operation of a button or a remote controller provided on one side of the display device 1. . The motor 226 is then rotated in the reverse direction. Then, the links are operated in a direction opposite to the direction in which they are drawn in, and the external device 3 is pulled out by a predetermined distance.

When the first link 220 is completely rotated, the switching terminal of the micro switch 250 is aligned with the insert groove 251 formed on the outer circumference of the first link 220, and the micro switch 250 generated at this time is generated. The operation of the motor 226 is terminated by the signal of. Of course, in this case, the alignment of the locking groove 320 and the push protrusion 225 is released, so that the user can pull out the external device 3 to the outside. Then, when the user pulls out the external device 3, the door 202 is returned to the original position by the door spring 203.

According to the present invention, the user can conveniently enter or withdraw the external device into the bay. Of course, it is possible to further propose various structures in which the external device is drawn out or drawn in, but the operation of drawing out or drawing out the external device is automatically performed by the power of the motor, whereby the external device can be conveniently operated. It is easy to guess.
