Description

  The present invention relates to a video display device such as a digital television broadcast receiver.

  As is well known, in recent years, digitalization of television broadcasting has been promoted. For example, in Japan, not only satellite digital broadcasting such as BS (broadcasting satellite) digital broadcasting and 110-degree CS (communication satellite) digital broadcasting but also terrestrial digital broadcasting has been started.

  In a television broadcast receiving apparatus that receives a television broadcast, for example, a broadcast program is automatically recorded based on a genre, a keyword, or the like set by the user, and a user is required from the recorded program. Some have a function of selecting and viewing a program.

  In this case, a recording / reproducing apparatus for recording / reproducing a broadcast program requires a large recording capacity capable of recording a large number of programs, and quickly searches for and reproduces a desired program from the recorded programs. HDD (hard disk drive) is adopted because access performance that can be performed is required.

  By the way, in the current television broadcast receiving apparatus (video display apparatus), a video signal is stored in a storage medium connected to the main body from the outside, and video signal processing is performed on the video signal stored in the storage medium. Some of them can be displayed on the video display unit.

  Here, Patent Document 1 discloses a configuration in which a timer counter is started after the HDD is stopped to monitor whether or not the driving stop state continues until an allowable limit period.

However, it cannot be said that the technology relating to the exchangeable HDD module and the technology using a plurality of HDD modules are sufficiently disclosed in practical terms.

  Accordingly, the present invention has been made in view of the above circumstances, and an object thereof is to make it possible to use a replaceable HDD module and to use a plurality of HDD modules.

  The video display device according to the present invention comprises means for acquiring an identifier unique to each storage medium attached to each storage medium connected to the main body from the outside and storing it in a storage unit connected to the main body, and an identifier unique to the storage medium Is stored in the main body, time measuring means for measuring the time when the storage medium is removed from the main body, comparing means for comparing the measured time with a preset specified value, and the measured time is set in advance. And a display means for displaying the storage medium in which the identifier unique to the storage medium is stored in the main body on the display unit so as to be connected to the main body when the specified value is reached.

  The video display method according to the present invention includes a step of acquiring an identifier unique to each storage medium attached to each storage medium connected to the main body from the outside and storing the identifier in a storage unit connected to the main body; Measuring the time when the storage medium storing the identifier is removed from the main body, comparing the measured time with a predetermined value set in advance, and the measured time being set in advance And a step of displaying, on the display unit, the storage medium in which the identifier unique to the storage medium is stored in the main body when connected to the main body.

  With the configuration described above, there is an effect that the HDD module can be exchanged for the video display device. In addition, there is an effect that a plurality of HDD modules can be used.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing an external appearance of a video display device (television broadcast receiving device) 11 described in the embodiment of the present invention. That is, the television broadcast receiving apparatus 11 is mainly composed of a thin cabinet 12 formed in a substantially square shape as a main body of the apparatus, and a stand 13 for standing and supporting the cabinet 12.

  The cabinet 12 exposes a display screen 14a of a video display 14 made of, for example, a flat-type liquid crystal display panel, and a pair of speakers 15, an operation unit 16 and a remote controller (described later). A light receiving unit 18 for receiving operation information transmitted from 17 is disposed.

  The stand 13 is formed in a substantially thin box shape, and the bottom plate 13a, which is one of the planes, is placed on a predetermined base (not shown) installed horizontally. It is configured. The stand 13 is connected to a back surface of the cabinet 12 by a support member 19 projecting upward from a substantially central portion of the upper surface plate 13b which is a surface opposite to the surface placed on the base. Thus, the cabinet 12 is supported in an upright state.

  Here, the stand 13 can accommodate an HDD unit (not shown in FIG. 1) 20 to be described later. On the upper surface plate 13b of the stand 13, a plurality of pressable operations (not shown) for controlling the HDD unit 20 to be recorded, reproduced, stopped, etc., are projected to the front side of the cabinet 12. In this case, four operation elements 21 are arranged.

  FIG. 2 is a diagram schematically showing a signal processing system of the video display device 11 described in the embodiment of the present invention. The various circuit blocks constituting the signal processing system are mainly disposed in the cabinet 12 at a position close to the back surface, that is, around the back side of the display screen 14a of the video display 14.

  The digital television broadcast signal received by the digital television broadcast receiving antenna 22 is supplied to the tuner unit 24 via the input terminal 23. The tuner unit 24 selects and demodulates a signal of a desired channel from the input digital television broadcast signal. Then, the signal output from the tuner unit 24 is supplied to the decoder unit 25 and, for example, subjected to MPEG (moving picture experts group) 2 decoding processing, and then supplied to the selector 26.

  Further, the analog television broadcast signal received by the analog television broadcast receiving antenna 27 is supplied to the tuner unit 29 via the input terminal 28. The tuner unit 29 selects and demodulates a signal of a desired channel from the input analog television broadcast signal. The signal output from the tuner unit 29 is digitized by an A / D (analog / digital) conversion unit 30 and then output to the selector 26.

  The analog video and audio signals supplied to the analog signal input terminal 31 are supplied to the A / D converter 32 and digitized, and then output to the selector 26. Further, the digital video and audio signals supplied to the digital signal input terminal 33 are supplied to the selector 26 as they are.
