JP 2008-147993 A

  Recently, the display device with the built-in video recording / reproducing apparatus has a connector for attaching the HDD in addition to the HDD fixed inside, and the user can attach a portable HDD to record and reproduce the broadcast program. Something like that has appeared. Since the HDD can be removed, there is an advantage that it can be played back on a display device in another room or another house. Including the HDD fixedly provided in the inside described above, either one can be selected or both of them can be used simultaneously. A portable HDD is often referred to as iVDR (abbreviation of Information Versatile Disk for Removable usage, which is a registered trademark meaning the technical standard of the iVDR consortium).

However, if two HDDs of a fixed type and a portable type are provided in one display device, in the conventional display device, for example, a flexible wire, a relay substrate, a base chassis between the HDD and the circuit board of the display device. There is a problem that the number of attachment members and the like increases twice as compared with the conventional one. In many cases, these lead to increased prices, and it has been desired to reduce the number of parts.
An object of the present invention is to solve this problem and to provide a display device and a video recording / reproducing device with a reduced number of components.

  In order to achieve the above object, the present invention inputs video information, displays the input video information as a video, records the input video information in a video recording / playback apparatus, and plays back the video information from the video signal recording / playback apparatus A display device with a built-in video recording / playback device for displaying video information, the first video recording / playback device built in the display device, and a second video configured to be detachable from the display device A tray in which a mounting portion of the recording / reproducing device, a portion for holding the first video recording / reproducing device, and a portion for holding the second video recording / reproducing device attached to the display device are integrally formed. It is characterized by having.

  The present invention also relates to a video recording / reproducing apparatus for recording and reproducing input video information, the first recording medium built in the apparatus, and a first recording medium configured to be detachable from the apparatus. A tray in which an attachment portion for the second recording medium, a portion for holding the first recording medium, and a portion for holding the second recording medium attached to the apparatus are configured integrally; A relay board to which the first and second recording media are connected, and on one side of the relay board, a first connector to be connected to the first recording medium is provided, A second connector connected to the second recording medium is provided on the other side opposite to the one side.

  According to the present invention, it is possible to provide a display device and a video recording / reproducing device with a reduced number of components, which can contribute to effective use of material resources without impairing the user's convenience. .

1 is a block diagram of a display device with a built-in video recording / reproducing apparatus showing an embodiment of the present invention. 1 is an overview of the periphery of a video recording / reproducing apparatus showing an embodiment of the present invention. It is a front view of the holder in one Example of this invention. It is the front view and side view of the attachment part of the video recording / reproducing apparatus which show one Example of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram of a display device with a built-in video recording / reproducing apparatus showing an embodiment of the present invention. Based on this, the overall operation will be described. The broken lines in the figure indicate the boundary between the inside and the outside of the display device, and the components on the line indicate the elements related to the interface between them, such as connectors and input terminals.

  A broadcast wave from an antenna (not shown) is supplied to the input terminal 100, and a tuner 101 selects a broadcast channel desired by the user. Of course, not only satellite broadcasting and terrestrial broadcasting but also cable television broadcasting may be received. The channel to be selected is determined when the user operates a remote controller (not shown), for example, to send a selection command to the remote controller receiving unit 109 and the CPU 110 controls the tuner unit 101 via the bus 108 based on the selection command. . The received signal of the selected channel is demodulated in accordance with the modulation scheme applied for transmission by the demodulator 102, and errors generated during transmission are corrected. Next, the descrambling unit 103 decrypts the encryption applied to improve the confidentiality at the broadcasting station as necessary.

  For example, three programs (also referred to as video content and video information) are time-division multiplexed on one broadcast channel, but in the same way as described above, the demultiplexer 104 is configured so that the user can The video content of the desired slot is selected. In the MPEG decoder 105, the selected video content is decompressed and decompressed by the data compression / encoding by MPEG (Moving Picture Experts Group) performed by the broadcasting station, and becomes the three primary color signals for display on the display unit 106. Given. The user can view the program displayed on the display unit 106.

  In order to avoid complication of the drawings, an audio signal processing circuit and a speaker are omitted. Naturally, audio information accompanying the video content is also signal-processed and output to the speaker. When displaying an EPG, the program information sequentially received along with the broadcast is stored in, for example, the flash memory 107, and then the program information of all channels is displayed in a time-sequential manner in a list format of a predetermined format. 106.

  When the user makes a recording reservation for a specific program using the EPG, the CPU 110 sends a command for notifying the HDD controller 111 of the start of the recording operation when the reservation time approaches. When the start time of the corresponding program is reached, the HDD control unit 111 instructs the recording / playback unit described later to start the recording operation. At this time, the demultiplexer 104 provides the HDD control unit 111 with the content data of only the program reserved for recording by the user and the program information of only the program separately from the received broadcast signal.

  As the recording / reproducing unit, there is an HDD 112 as a recording medium fixedly provided inside the display device so that the user cannot remove it, and is connected to the HDD control unit 111 via the bus 113. . The bus 113 is also supplied to the connector 114b. The connector 114b is a connection terminal of the iVDR 115, which is an HDD as another removable recording medium, and is composed of 26 pins, for example. If the user attaches the iVDR 115 as necessary, the content data and the program information described above can be recorded on either or both of the HDDs 112. In the present embodiment, it is assumed that the HDD 112 fixedly provided inside is also connected to the HDD control unit 111 via the connector 114a similar to the connector 114b.

  The selection of whether to record in the HDD 112 or iVDR 115 is made by the user operating a remote control, for example, to send a selection command to the remote control receiving unit 109, and based on this, the CPU 110 controls the HDD control unit 111 via the bus 108. You can do that. As described above, there are many cases where one of them is selected by a method such as selecting with a switch, but the present invention is not limited to this. As another method, the HDD control unit 111 is provided with a RAID (Redundant Arrays of Independent Disks) control function, and these two devices are controlled so as to function virtually as one large-capacity memory. When the capacity becomes full in the middle of the recording operation, control may be performed so that recording is performed by switching to the remaining one. It is also possible to provide two or more tuner units 101 and simultaneously record the television broadcast content data and program information received by each tuner in the HDD 112 and the iVDR 115, respectively.

Further, although the connector 114b is at the boundary of the display device, this is on the block diagram of the electric circuit, and may be inside the display device in terms of structure. In this case, a hole for inserting the iVDR 115 is provided in the housing of the display device, and the user inserts the iVDR 115 from this hole and attaches it to the internal connector 114b.
The HDD control unit 111 controls the HDD 112 or iVDR 115 to record these data for each predetermined sector. The program content data and the program information are recorded in different areas, but the program information is recorded by adding information indicating the recording location of the content data.

  When playing back a program recorded on the HDD 112 or iVDR 115, the user displays a recorded program list on the display unit 106 using, for example, a remote controller. The recorded program list is created based on the recorded program information. In addition to the recorded date, time length, channel, etc. for each recorded program, a thumbnail image that informs the contents of the program may be displayed. The user sees this and selects a program to be played using, for example, a remote controller. Since the program selected at that time is reproduced and displayed on the display unit 106, viewing by so-called time shift becomes possible.

  A structure centering on the HDD 112 and the iVDR 115 will be described later with reference to the drawings. In the embodiment of FIG. 1, these are mounted on one tray. Conventionally, for example, the HDD 112 has been arranged at a position away from the iVDR 115. For this reason, it is necessary to individually provide the flexible wires forming the bus 113 one by one. However, in this embodiment, the flexible wires can be shared by one, and the number of parts can be reduced. As described above, the connector 114b has 26 pins, for example, and the flexible wire becomes expensive, so that the price can be reduced.

Next, structural features of the present embodiment will be described with reference to FIG. FIG. 2 is a schematic view of the periphery of the video recording / reproducing apparatus showing an embodiment of the present invention. The same constituent elements as those in FIG. 1 are denoted by the same reference numerals.
The main signal board 8 is not shown except for the connector 81 among the components to be mounted. For example, the tuner 101 to the HDD control unit 111 of FIG. 1 are mounted. A relay board 2 to which the HDD 112 and the iVDR 115 are connected is attached to a substantially central portion of the tray 3 in the longitudinal direction (left-right direction in the drawing). 113 is connected. As described above, the bus 113 is made of a flexible wire. The connector 114a shown in FIG. 1 is provided on one side of the relay board 2, and the connector 114b is provided on the other side opposite to the one side. The HDD 112 is provided in the former and the iVDR 115 is provided in the latter. It is attached. That is, in this embodiment, the connector 114 a and the connector 114 b are arranged side by side in the longitudinal direction of the tray 3. The insertion direction of HDD 112 into connector 114a (the direction from left to right in the drawing) and the insertion direction of iVDR 115 into connector 114b (the direction from right to left in the drawing) are opposed to each other. Yes. Thereby, the wiring pattern on the relay substrate 2 can be simplified, and the area of the relay substrate 2 can be reduced. The connector 114a is fixedly provided inside the display device, and the HDD 112 cannot be detached from the connector 114a by a general user, but the iVDR 115 can be detached from the connector 114b by the user. The iVDR 115 can be detached from the right direction in FIG.

  The tray 3 mounts and holds the HDD 112, iVDR 115, and relay substrate 2. In this embodiment, for example, PC (polycarbonate), ABS (acrylicitol, butadiene, styrene copolymer synthetic resin) or PC and ABS are used. These are formed by molding a synthetic resin or a resin material such as PS (polystyrene). By configuring the tray 3 in this manner, the portion of the tray 3 according to the present embodiment that holds the HDD 112 and the portion that holds the iVDR 115 when the iVDR 115 is attached to the connector 114b are integrated. Conventionally, this tray is provided separately for the one holding the HDD 112 and the one holding the iVDR 115. In the drawing, the tray having a lateral length of about half was disposed at a different position with respect to the main signal board 3. For this reason, two flexible wires, the relay board 2, and the connectors 81 and 114c constituting the bus 113 are required. In the configuration of the present embodiment, both the recording medium drives are held by one tray 3, so that they can be used in common and the number of parts can be reduced.

The present embodiment is also characterized in that both recording medium drives are held by one tray 3 and can be easily assembled as one structure. Next, this feature will be described.
In FIG. 2, the base chassis 9 is made of a metal such as aluminum or iron, and has a structure for supporting and reinforcing the back surface of the display device. Here, the holders 5a to 5f are attached to the base chassis 9 at a substantially right angle. As will be described in detail later, the holders 5a to 5f have, for example, U-shaped or C-shaped grooves as shown in FIG. The previous tray 3 has shafts 6a to 6f (of which 6a, 6c and 6e are in an invisible position). The dampers 4a to 4f made of an elastic body attached to this have a groove at substantially the center in the thickness direction. The tray 3 to which the HDD 112 and the iVDR 115 are attached is fixed to the base chassis 9 by inserting the grooves of the dampers 4a to 4f into the grooves of the holders 5a to 5f. The holders 5a to 5f may be formed integrally with the base chassis 9 by machining it. Further, the shafts 6 a to 6 f may be configured integrally with the tray 3.

  Although FIG. 2 shows a case where the dampers 4a to 4f, the holders 5a to 5f, and the shafts 6a to 6f are provided, the number of the dampers may be 3 to 5. For example, if there are three, only members a, d and e are used. In the case where the conventional one holding the HDD 112 and the one holding the iVDR 115 have separate trays, two sets of three to four members are required. The number of attachment members can also be reduced.

Next, the attachment method in a present Example is demonstrated. Since the tray 3 is longer in the lateral direction in FIG. 2 than the conventional tray as described above, the tray 3 is easily attached by the method described below.
First, the holders 5a to 5f will be described with reference to FIG. FIG. 3 is a front view of the holder in one embodiment of the present invention. Here, a feature is that both a holder 51 having a U-shaped groove as shown in FIG. 3A and a holder 52 having a C-shaped groove as shown in FIG. 3B are used. . The width (inlet part) of the former groove shown as A in FIG. 3A is selected so as to be lightly engaged so as to slightly compress the grooves of the dampers 4a to 4f. On the other hand, the width (inlet part) of the latter groove shown as B in FIG. 3B is selected so as to be engaged so as to compress the grooves of the dampers 4a to 4f more strongly than the former. If all the holders are the former, they may come off with a light impact even if they are easy to attach. If all the holders are the latter, there is a problem that although they are firmly fixed, the meshing is too hard and is difficult to attach.

  Therefore, in the case of fixing with three pieces on one side, a total of six pieces as shown in FIG. 2, for example, the holders 5a, 5b, 5e, and 5f are the C-shaped ones of FIG. 3 (a) U-shaped. When the tray 3 is attached to the base chassis 9, it can be easily attached by first positioning the tray 3 with respect to the holders 5 c and 5 d at the center, and the possibility of coming off due to impact can be reduced. Further, when the members indicated by c and d do not exist and are fixed at the remaining four locations, the holders 5a and 5f are the C-shaped ones of FIG. 3B, and the holders 5b and 5e are the same as those shown in FIG. ) U-shaped. Of course, the combination may be reversed. If it is inserted after positioning with respect to the holders 5b and 5e which are substantially on the diagonal, it can be easily attached and the possibility of coming off due to impact can be reduced.

  In the above description, the shape of the groove of the holder is expressed as a U-shape or a C-shape, but this is an example, and the present invention is not limited to this. The groove widths (inlet portions) indicated by A to B in FIG. 3 may be different as described above. The wider groove may be C-shaped, and the narrower groove may be U-shaped. Moreover, it is not limited to a U-shape or a C-shape, and in short, a holder having a different groove width may be used.

  Next, a structure for correctly engaging the groove of the holder and the groove of the damper will be described with reference to FIG. FIG. 4 is a front view and a side view of a mounting portion of a video recording / reproducing apparatus showing an embodiment of the present invention. The front view seen from right above FIG. 3 and the side view from each direction are shown side by side in the form of a development view. FIG. 4 shows a state in which the HDD 112 and the iVDR 115 are removed, unlike FIG. The dampers 4c and 4d at the positions c and d are removed from the six fixed portions so that the shapes of the shafts 6c and 6d can be seen. Of course, the shapes of the shafts 6a, 6b, 6e, and 6f may be the same. As described above, the dampers 4a to 4f have a groove at the center in the thickness direction, and the damper 4a to 4f meshes with the U-shaped or C-shaped groove of the holders 5a to 5f. Fixed. However, it is conceivable that the grooves of the holders 5a to 5f do not enter the grooves of the dampers 4a to 4f but enter the trays of the dampers 4a to 4f, for example, due to a slight difference in position. In this embodiment, corresponding to this, guides 7a, 7b, 7e and 7f are provided on a part of the tray as shown in FIG. At the time of attachment, these guides act so that the holders 5a to 5f do not approach the side surface of the tray 3 more than a predetermined amount, and the grooves of the holders 5a to 5f are engaged with the grooves of the dampers 4a to 4f. Note that the guides 7a, 7b, 7e, and 7f for the holders 5a, 5b, 5e, and 5f at both ends are not as important in positioning the holders 5c and 5d at the center, but are not illustrated. Of course, this may be provided.

  In FIG. 4, the shafts 6c and 6d are drawn so that the shapes thereof can be understood. It is characterized by having a bulge (sometimes referred to as a protrusion) for holding the damper so as not to be detached from the shaft at the outer end. Thereby, the damper made of the elastic body is fixed so as not to be easily detached from the shaft. Conventionally, for this reason, the stepped screw is pushed in from the end of the shaft toward the tray 3 without providing a bulge, but in this embodiment, it can be fixed by a simple method.

  In addition, the above embodiment is an example to the last and this invention is not limited to this. What is connected to the connector 114b in FIG. 1 is not limited to the iVDR 115 as described above, and may be, for example, an optical disc such as a BD (Blu-ray Disc) or DVD having a diameter of 8 cm. Many more embodiments with various modifications are conceivable as described above, all of which fall within the scope of the present invention.

  Furthermore, in the above example, an example in which a fixed HDD and a mechanism in which a portable HDD (iVDR) is inserted is provided in the display device, but the present invention is not limited to this. . It is also possible to apply the present invention to a video recording / reproducing apparatus such as an HDD recorder that does not have a display unit for displaying video.
