Abstract

The present invention implements continuous playing suitable for intention of a content producer. A playing control unit plays image content which is previously recorded on recording medium. A script control unit is memorized on the recording medium previously and interprets a script program including an event handler to be executed when there is an event in the playing control unit. A data memorizing unit has an area for memorizing backup information of a playing status, which is information for continuously playing the image content from the last time. A script control unit playing the image content continuously with respect to the playing status information according to the occurrence of the event by the playing control unit.

Description

TECHNICAL FIELD [0001] The present invention relates to a visual data playing method and a program,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reproducing technique for reproducing and displaying image contents recorded on a recording medium such as a disc.

2. Description of the Related Art In recent years, image reproducing apparatuses for reproducing contents such as moving pictures and games recorded on a recording medium on a disc such as a DVD have become widespread. In the reproduction-only DVD video standard, a user performs an interactive function by using a button image or the like arranged on a menu screen. For example, during reproduction of a moving image by DVD video, a menu screen is called by using a remote controller or the like, and a button image arranged on the menu screen is selected to change the reproduction scene. In general, since a large amount of data can be recorded on a recording medium such as a DVD, the video content can be reproduced for a long time. As the video content becomes longer, it is difficult to view all of the content with one playback, so that the number of times the user stops playing the video content increases. It is inconvenient for the user to search for the content by using the function of quickly rotating the previously reproduced point each time the content is restarted. Therefore, the point where the reproduction of the video content is stopped is stored in the DVD playback apparatus, (Hereinafter referred to as "continuous playback") for restarting the content from the point where the previous playback is stopped.

A problem to be solved by the present invention is that a different event handler is selected and executed in accordance with the presence or absence of the storage of the reproduction status, and therefore, for example, a first event handler is used at the time of first reproduction, The first event handler is referred to as an " onAutoPlay () event handler "in the embodiment, and the" second event handler " OnContinuePlay () event handler "of " onContinuePlay () ". The storage unit may have an area for storing user data which is information dependent on the image content. In this case, when executing the second event handler, the script control unit may execute continuous reproduction using the user data. According to this, various kinds of data suited to the contents can be stored in the video reproduction apparatus in accordance with the intention of the content creator, and the user data can be acquired at the time of the next video reproduction. The script program may further include a third event handler that is executed in accordance with the end event in the playback control. In this case, the script control unit allows the reproduction status or information of the user data to be manipulated by execution of the third event handler. According to this, by describing the third event handler as the event handler executed in response to the end event, the operation intended by the content creator can be realized at the end of the playback of the video content. As an example, the "third event handler" corresponds to the "onExit () event handler" in the embodiment. Also, the expression of the present invention is converted between a method, a system, a computer program, a recording medium and the like is also effective as an aspect of the present invention.

One embodiment of the present invention relates to a video reproducing apparatus for reproducing audio and video contents recorded on a recording medium such as a DVD disc. In such an apparatus, a menu screen for selecting the playback and playback scenes of the main content such as the main story of the movie or a menu screen for setting the image quality or sound quality And so on. Next, the general operation of the video reproducing apparatus will be described, and finally, the continuous reproduction according to the present invention will be described in detail. The disk is a recording medium on which the content data and the data necessary for reproduction are recorded. When the disc is inserted into the disc drive, data is read and playback of the video content by the video playback apparatus is started. A medium other than a disk such as a memory card or a memory cartridge may be used as the recording medium.

According to the present invention, since the operation at the time of continuous reproduction is described as a script program on the recording medium side and the reproduction status, which is information required for continuous reproduction, is stored by the video reproduction apparatus, The continuous reproduction can be realized as intended.

The above-described continuous playback function is not set in the standard of the DVD but is a function provided separately on the playback apparatus side of the DVD. In some cases, depending on the type of image content, the content creator may want to perform playback as intended.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a video reproducing technique for realizing continuous reproduction in accordance with the intention of a content creator in a video reproducing apparatus of a recording medium such as a DVD disc. Some aspects of the present invention provide an image reproduction apparatus. This apparatus includes a playback control unit for playing back image content recorded on a recording medium in advance, a script program stored in advance on the recording medium and including an event handler that is executed when an event occurs in the playback control unit, And a storage unit having an area for storing a playback status, which is information for playing back the video content that has been played back previously from the next time. The script control unit causes the playback control unit to continue playback of the video content by referring to the playback status in accordance with the occurrence of the event in the playback control unit. According to this aspect, And the playback status, which is information required for continuous playback, is stored in the video playback device, so that the continuous playback as intended by the content creator can be realized by appropriately creating a script program. Here, as the "playback status ", for example, a play list number, a file number of a video stream being executed, a reproduction time, and the like can be used.

The script program may include a first event handler for playing back the image content from the beginning and a second event handler for executing continual playback with reference to the playback status. In this case, at the time of loading of the recording medium, the script control unit searches the storage unit for the reproduction statuses corresponding to the image contents recorded on the recording medium, and, depending on the presence or absence of the corresponding reproduction status, Select one and execute it.

Claims (1)
