DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording and reproducing apparatus capable of instantly calling and reproducing recorded information such as video information and audio information recorded on a DVD (digital video disk).

[0002]

2. Description of the Related Art For example, various sales methods such as over-the-counter sales and direct mail sales methods are used for selling products. Among these sales methods, the door-to-door sales method is also a frequently used sales method. In the door-to-door sales method, after educating the sales staff on the knowledge of the product to be sold, they visit the customer directly by carrying sample products, advertising media, etc., introduce and explain the product, and try to obtain a sales contract. is there.

[0003] Recently, Japan is about to enter an aging society, and there is a potential labor force for middle-aged and elderly people who have passed retirement age. In the field of door-to-door sales, we are focusing on the potential efforts of these middle-aged and elderly people, and are actively hiring middle-aged and elderly people as door-to-door sales staff.

[0004] Door-to-door sales clerks of the middle-aged and older age groups are more skilled in talkative sales methods and product knowledge than those of the younger age group, but have an understanding and use of recent product knowledge mainly on high-tech products. In learning how to do it, younger door-to-door salespeople outperform middle-aged and older ones. In order to cover such weaknesses, in recent years, it has been customary to provide sales representatives with photographs (still images) of all products handled by door-to-door dealers, moving images showing the use status and functions, or detailed mechanism explanations. Provide a variety of information that can be explained in detail directly to the customer.
The DVD is recorded on a DVD disk which has better image quality and sound quality than the CD. On the other hand, the visiting salesperson is required to hold a portable DVD recording / reproducing apparatus equipped with the DVD and record the DVD at the destination. Read the desired image from the data and display the very clear and high-quality product information on the screen of the recording / reproducing device. The visiting salesperson explains the product while showing this image to the customer and proceeds with the visiting sales. go.

To briefly explain the recording structure of a DVD, first, there is a level called a volume as the highest hierarchy. This level is the same as a structural volume such as a hard disk. The lower level of the volume has a level called a title. At the level of this title,
A so-called progress table is described, which describes a time-sequential reproduction order of cells, which is called a cell, in which sequence of data recorded with video and audio is reproduced.

There are two types of titles, a linear type title and a non-linear type title. In a linear type title, cells as components that record information such as video and audio are arranged in a predetermined order, and are reproduced in a single path from the beginning to the end without branching. On the other hand, in the case of a non-linear type title, a branch operation programmed so that the reproduction operation is automatically branched from the operation history or the like is added during the reproduction.

[0007] When a target video is to be viewed from a large number of video information recorded on the DVD using a conventional DVD, when the DVD is divided into a plurality of volumes, the volume selection screen is displayed. Select a number. With this operation, a desired volume is selected. Then, a maximum of 99 title names included in the selected volume are displayed. Further, when a desired one is selected from the title names, a plurality of information recording groups recorded in the title are displayed. If the title is, for example, a linear type, sub-names for up to 99 pieces of information are displayed, the user selects a desired one from among them, and finally a desired image is displayed on the screen.

[0008]

In a DVD created for explaining a door-to-door sales, for example, one DVD is set in one volume, and a title of a higher-ranking product (home electric appliance, OA equipment, food) is set as a title. Goods, furniture, etc.), and in the title, information such as a photograph of a product and a handling method are recorded with unique sub-names.

[0009] When trying to explain a product using a DVD, each visiting sales person carries a recording / reproducing apparatus equipped with the DVD as described above. A device is used to reproduce a desired image, to display goods by images or to show functions, and to attempt to summarize negotiations. However, in the conventional recording / reproducing device, the volume selection screen is skipped, a title name is displayed on the screen, and a desired title is selected from the displayed titles. Then, on the screen, the sub-names included in the selected title are displayed one after another, and the screen waits for selection. When the presenter selects a desired subtitle from the displayed subnames, the screen of the desired subtitle is displayed on the screen. However, the conventional DVD recording / reproducing apparatus employs a standardized reproducing procedure. In some cases, it may take several minutes for the final image to be displayed after two selection scenes after the sales representative attempts to display the image. If the recording / reproducing device cannot display an image for several minutes after the purchase power of the customer elapses, the purchase power generated by the customer is diminished, and the business opportunity is lost. .

An object of the present invention is to solve the above-mentioned conventional inconvenience, and an object of the present invention is to allow a salesperson carrying a recording / reproducing apparatus to instantly display a desired screen on a screen of the recording / reproducing apparatus. It is an object of the present invention to obtain a DVD recording / reproducing apparatus capable of causing a DVD to be read.

As shown in FIG. 2, the main video recording section 2 is divided into cells, and these cells are sequentially numbered, for example, cell numbers 1 to n in the order in which the information is reproduced. In this cell, a minimum unit of a video signal, an audio signal, and the like are divided into a plurality of channels and are recorded after being compressed by the MPEG system.

Returning to the description of FIG. 1, the DVD disk has a main video recording unit 2 and a sub video recording unit 3.
The sub-picture recording unit 3 is called a sub-picture recording unit because sub-information is recorded with respect to the information recorded in the main video recording unit 2. The sub-picture recording unit 3 includes a part for recording a subtitle used for a language translation subtitle and the like as additional information imposed on the main picture, and a screen showing a procedure for suggesting the next recording / reproducing operation to the user. It has a menu section for recording data to be created, programs for executing procedures, and the like.

In a DVD, up to 32 tracks are usually prepared for subtitle recording.
Content descriptions other than languages and subtitles can be recorded. There are two screens displayed on the basis of the information of the menu portion, namely, a system menu and a menu in a title. The system menu can be displayed on the screen at the time of starting or stopping the reproduction of the disc or during reproduction. The title or the like displayed in the system menu is selected, and the recording / reproducing apparatus is operated according to the selected menu. The menu in the title allows a subtitle to be displayed on the screen during disc playback and can be selected.

Referring to the hierarchical recording structure of DVD, FIG.
As shown in the figure, the upper layer is the volume level. For the volume, a DVD disk is
It is necessary when using as a ROM,
When used as a normal video recording disc,
You only have to handle one disk as one volume,
Usually there is no need to be hierarchically aware.

There is a title level below the volume level. Multiple titles can be placed at the title level. There are two types of titles, a linear type title and a non-linear type title. If the selected title is of the linear type, the selected cells are sequentially reproduced in a predetermined order. If the selected title is a non-linear type, for example, the reproduction of a desired route can be selected during reproduction according to the selection recorded in the sub-video recording unit 3.
