Abstract

PURPOSE:To retrieve the images of product catalogs, etc., which are recorded in a video tape easily and quickly by a method wherein a video tape retrieving apparatus is provided between a remote controller and a VTR and an address transmitted through a cable from the VTR is compared with a designated address to control the operation of the VTR. CONSTITUTION:A video retrieving apparatus 2 which is optically controlled by a remote controller 3 controls a VTR 1 connected to its with a cable 4 optically. An address transmitted from the VTR 1 through the cable 4 is compared with a designated address by the comparator 2b of the apparatus 2 and the VTR 1 is optically controlled through the light emitting unit 2c and the remote control signal receiver 1a of the apparatus 2 so as to make both the addresses agree with each other and image information recorded in a VTR tape are retrieved. With this constitution, the images of product catalogs, etc., which are recorded in the video tape can be retrieved easily and quickly.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video tape retrieval apparatus for retrieving a video tape recorded with a mail order merchandise catalog or various files using a home VTR.

[0002]

2. Description of the Related Art Conventionally, mail order merchandise catalogs are mainly printed matters and are hardly recorded on video tapes. The reason is that, in order to quickly search a video tape and read out a desired frame, an expensive dedicated search device and a high degree of expertise to use it are required, and such a search device is popularized in all homes. Because it was difficult.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to use a VTR in each home and use a signal sent from a remote controller to retrieve an image of a product catalog or the like recorded on a video tape easily and quickly. A tape retrieval device is provided.

[0004]

In order to achieve the above object, a video tape retrieval apparatus according to the present invention inputs a light receiving portion for receiving an output signal of a remote controller and an address signal read from a video tape in a VTR. A VTR operation control unit that creates a VTR operation control signal by comparing a wired connection with an address signal read from a video tape with an address designated by a remote controller, and an output signal of the VTR operation control unit from a VTR light receiving unit. And a light emitting unit for transmitting to

[0005]

The video tape retrieval device is arranged between the remote controller and the light receiving section of the VTR, and when the desired address of the video tape is inputted by the channel designating switch of the remote controller, the VTR operation control section is designated. The address and the address signal read from the video tape input from the VTR via the wired connection are compared, an operation control signal for controlling the operation of the VTR is created, and this signal is input to the VTR to control the operation. Search for the desired frame on the videotape and read the image.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A video tape retrieval apparatus according to an embodiment of the present invention will be described with reference to the drawings. VTR for home
A video tape search device 2 is arranged on the front surface of the remote control signal light receiving unit 1a. A light receiving section 2a for receiving an output signal of the remote controller 3 is provided on the front surface of the video tape search device 2, and an output of the VTR operation control section 2b (opposed to the remote control signal light receiving section 1a of the VTR 1) is provided on the rear surface thereof. A light emitting unit 2c that transmits a signal is provided. The video tape retrieval device 2 and the VTR 1 are connected by a wire 4 such as a coaxial cable, and the address code read from the video tape in the VTR 1 is input to the VTR operation control section 2b.

The signal designating the address code sent from the remote controller 3 is received by the light receiving section 2a and input to the VTR operation control section 2b. The VTR operation control unit 2b uses the address code designated by the remote controller 3 and the VTR1.
The address control code read from the video tape input via the cable 4 is compared, and an operation control signal for controlling the operation of the VTR 1 is generated so as to match both codes. The operation control signal generated in the VTR operation control section 2b is transmitted from the light emitting section 2c, is input to the VTR 1 from the remote control signal light receiving section 1a, and controls the operation of the VTR 1 to retrieve the designated frame.

On the video tape on which (for example) a mail-order product catalog to be searched is recorded, a moving image of 15 seconds is recorded for each product, and the address code is recorded on all the frames. The address code consists of an index code that specifies each product (for example, 4 digits) and a frame code that specifies each frame (for example, 4 digits). To specify the product, enter only the index code and set the frame. If you want to specify it, specify the frame code further. The address code is recorded in the treble range or image signal of the normal audio track or hi-fi track corresponding to each frame. In addition, the video tape has a general index for searching for (the address code of) the desired product, which is classified into a large classification, a middle classification,
It is classified into various categories, such as sub-classification, etc., and several frames are recorded for each.

In use, the address code of the desired product is searched by operating the channel designating switch of the remote controller 3 to call up the general index and searching through several steps, and further operating the channel designating switch to obtain the desired address. Enter the code (index code of). Then, the VTR operation control unit 2b compares the designated address code with the address code read from the video tape fed back from the VTR 1 through the wired 4 connection, and the VTR1 is matched so that both codes match.
Create a motion control signal to control the motion of the
By inputting to TR1, the operation is controlled to search the image of the desired product on the video tape, and the image is read from the leading end of the image. If a specific still image is desired to be viewed, further input of a frame code (for example, a still image viewed from an appropriate angle of the product) is searched and displayed as a still image. The input of the general index, the index code, and the frame code can be distinguished by pressing the channels 10, 11 and 12 respectively (for example) and then inputting them successively.

In the above embodiment, the video tape retrieval device is arranged in front of the remote control signal light receiving portion of the VTR, but the invention is not limited to this, and the point is that the signal from the remote control is (VTR If the positional relationship is such that the signal is input to the light receiving portion of the video tape retrieval device (without being input to the remote signal receiving portion of the VTR) and the signal transmitted from the light emitting portion is input to the remote signal receiving portion of the VTR. It is enough. Further, the recording time, the number of digits of the index code and the frame code, etc. for each product are not limited to those in the above embodiment, but can be set appropriately.

[0011]

As described above, the video tape retrieval apparatus of the present invention uses a VTR in each home to easily and quickly retrieve a large number of images recorded on a video tape by a signal sent from a remote controller to produce a moving image. Can be displayed both as and as a steel, and can be searched easily and inexpensively without using specialized search equipment without using specialized search equipment. For mail-order product catalogs, door-to-door demonstrations, etc. It has an excellent effect that it can be widely and easily used as various databases such as personnel files, graduation albums, and picture books.
