Embodiment Construction

[0020] According to the subtitle file loading method of the present invention, the memory is divided into two memory blocks (or multiple memory blocks), and the subtitle files to be played are loaded from the digital audio-visual disc in an alternate manner. When another storage block of the memory transmits the stored subtitle file to the subtitle file decoder for decoding, another storage block performs loading of the subtitle file. Therefore, at any moment, as long as the subtitle file decoder needs the subtitle file, the memory has a subtitle file that can be delivered to the subtitle file decoder for decoding. In this way, when the subtitles are played, there will be no need to wait for the memory to be replaced by the digital audio and video. When the disc is loaded with subtitle files, the playback pause caused by it.

Abstract

A subtitle file loading method is used for loading the subtitle file in the digital audio-visual disc into the memory in the digital audio-visual disc playback device. The memory has a first storage block and a second storage block. Firstly, the first multiple subtitle files are loaded into the first storage block of the memory. Subsequently, the first plurality of subtitle files loaded into the first storage block are delivered to a subtitle file decoder for decoding, and at the same time, the second plurality of subtitle files are loaded into the second storage block of the memory. Next, the second plurality of subtitle files loaded into the second storage block are delivered to the subtitle file decoder for decoding, and at the same time, the third plurality of subtitle files are loaded into the first storage block of the memory. In this alternate manner, repeat the above steps until all subtitle files are loaded.

Description

technical field [0001] The present invention relates to a subtitle file loading method for a digital audio-visual disc, and more particularly, relates to a subtitle file loading method for a digital audio-visual disc that can improve processing efficiency. Background technique [0002] When the digital audio-visual disc player plays the subtitle file, it first extracts the subtitle file from the digital audio-visual disc, and stores it in a memory of the digital audio-visual disc player. Subsequently, the subtitle files stored in the memory are further sent to a subtitle file decoder for decoding. The subtitle file decoder decodes the subtitle file into an address signal and a display signal, which are respectively transmitted to the temporary register and the buffer for storage. The display signal contains subtitle information to be displayed, and the address signal controls the address of the display signal displayed on the display device. Subsequently, the display signa...
