    • An audio signal encoding and decoding apparatus capable of transmitting an audio signal or an audio signal together with a sound-field-effect-processed audio signal are provided. The audio signal encoding apparatus includes a core encoder to encode an input audio signal according to an audio signal encoding standard, a core decoder to decode the encoded audio signal output from the core encoder, a sound-field-effect processor to perform a sound-field-effect process on the input audio signal, a selector to selectively output the input audio signal or the sound-field-effect-processed audio signal output from the sound-field-effect processor, a subtraction unit to calculate a difference signal between the signals output from the core decoder and the selector, an extension encoder to encode the difference signal output from the subtraction unit according to an arbitrary encoding scheme and to output the extension encoded signal, and a multiplexer to multiplex the encoded audio signal output from the core encoder and the extension encoded signal output from the extension encoder into a composite encoded signal and to output the composite encoded signal.
    • 提供了能够将音频信号或音频信号与声场效应处理的音频信号一起发送的音频信号编码和解码装置。 音频信号编码装置包括:核心编码器,用于根据音频信号编码标准对输入音频信号进行编码;核心解码器,对从核心编码器输出的编码音频信号进行解码;声场效应处理器, 对输入音频信号进行场效应处理,选择器选择性地输出从声场效果处理器输出的输入音频信号或声场效应处理的音频信号;减法单元,用于计算声场效应处理音频信号 从核心解码器和选择器输出的信号;扩展编码器,用于根据任意编码方案对从减法单元输出的差分信号进行编码,并输出扩展编码信号;多路复用器,用于复用从核心输出的编码音频信号 编码器和从扩展编码器输出的扩展编码信号转换为复合编码信号并输出​​复合编码信号。

    • A method of reproducing one interactive graphics stream among one or more interactive graphics streams from an information storage medium, via a reproduction apparatus providing a visual display of interactive graphics, including obtaining attribute information in a player status register in the reproducing apparatus, and reading and reproducing one of the interactive graphics streams corresponding to the obtained attribute information among one or more interactive graphics streams from the information storage medium, the one interactive graphics stream being used to control reproduction of audio-visual data and being reproduced with the audio-visual data. With the method, text information written in a variety of languages and data shared by those languages are multiplexed and stored in one menu stream such that data is not redundantly stored and less storage space is wasted.
    • 一种通过提供交互式图形的视觉显示的再现装置从信息存储介质再现一个或多个交互式图形流中的一个交互式图形流的方法,包括获得再现装置中的玩家状态寄存器中的属性信息,以及读取和 在来自信息存储介质的一个或多个交互图形流中再现与所获得的属性信息相对应的交互式图形流中的一个,所述一个交互图形流用于控制视听数据的再现并且以视听数据再现 。 利用该方法,以各种语言编写的文本信息和由这些语言共享的数据被多路复用并存储在一个菜单流中,使得数据不被冗余地存储,并且减少了较少的存储空间。
