摘要： An optical disk system is presented which stores disk- and user-specific settings, along with an associated method. The optical disk system includes a disk drive unit for retrieving identification data and encoded video data stored upon an optical disk, an input device for inputting user settings, and a microprocessor memory unit having a non-volatile portion for storing the identification data and the user settings. Information specific to optical disks (e.g., DVDs) and users is stored within the non-volatile portion of the microprocessor memory unit. The user settings may include, for example, spoken language, video display format, audio volume setting, and subtitle language. The user settings may be retrieved and invoked, conveniently allowing a user to view a presentation (e.g., a movie), or to continue viewing an interrupted presentation, without having to reselect viewing and listening preferences. The identification data may include a portion of a title of the optical disk. A value corresponding to the identification data (e.g., a checksum) may be stored in order to minimize storage requirements. The non-volatile portion of the microprocessor memory unit may include, for example, flash memory or electrically erasable programmable random access memory (EEPROM) which maintains stored contents even in the absence of applied electrical power. A sleep timer function may be activated which requires periodic user input to continue playback and to save a current playback location.
摘要翻译：介绍了一种存储磁盘和用户特定设置以及相关方法的光盘系统。光盘系统包括用于检索存储在光盘上的识别数据和编码视频数据的盘驱动单元，用于输入用户设置的输入装置，以及具有用于存储识别数据和用户的非易失性部分的微处理器存储单元设置。特定于光盘（例如，DVD）和用户的信息被存储在微处理器存储器单元的非易失性部分内。用户设置可以包括例如口语，视频显示格式，音频音量设置和字幕语言。可以检索和调用用户设置，方便地允许用户查看演示文稿（例如，电影），或者继续观看中断的呈现，而不必重新选择观看和收听偏好。识别数据可以包括光盘的标题的一部分。可以存储对应于识别数据的值（例如，校验和），以便最小化存储要求。微处理器存储器单元的非易失性部分可以包括例如即使在没有施加的电力的情况下也保持存储的内容的闪速存储器或电可擦除可编程随机存取存储器（EEPROM）。可以激活睡眠定时器功能，其需要周期性的用户输入以继续播放并保存当前的播放位置。
