Problems solved by technology

In other words, where reproduction of a DVD-Video image from a conventional interactive DVD in synchronization with a markup file is requested, for example, in the context of his or her personal history whenever a particular actor or actress appears on the screen In case display is requested, the pickup device stops buffering AV data and starts searching and caching relevant markup files, and thus images can be reproduced discontinuously

Abstract

An apparatus which reproduces AV data using a markup document in an interactive mode includes a buffer which buffers the markup document, and a buffer manager which manages preloading of the markup document and provides buffering state information of the buffer in response to a report signal. The markup document may be provided via a network or form a data storage medium which includes information to control a buffering state of the markup document.

Description

technical field [0001] The present invention relates to a data storage medium with information for controlling the buffering status of a markup document, and more particularly to a method and device for reproducing data from the data storage medium. Background technique [0002] Interactive DVDs with tagged files to reproduce their contents in an interactive mode have been commercialized in the market. Generally, content recorded on an interactive DVD is reproduced in two modes. One of the two modes is a video mode in which content is displayed in the same manner as data is recorded on a general DVD. Another mode is the interactive mode, in which the content is displayed through a display window defined by the interactive DVD's markup document. [0003] In case the user selects the interactive mode, the web browser installed in the DVD player displays the markup document recorded on the interactive DVD. Displays user-selected content through a ...
