摘要： An information processing apparatus, contains a disc (12) storing a database with a set of records, each record containing a same set of fields, each record capable of containing record specific content in the fields. A disc drive (10) reads data from the disc (12) a fragment (F) at a time. Each fragment (F) contains a plurality of data blocks that are stored substantially contiguously on the disc (12). The disc drive (10) can be switched between a read mode and a power saving mode, wherein at least part of the disc drive (10) is disabled to cut power consumption. A user interface device renders a view of the database with selected records and fields from a user selectable one of a plurality of respective subsets of the set of records and/or fields of the records. The user interface (14, 16, 18) is programmed to command the disc drive (10) to switch to the read mode to retrieve fields from records from the selected subset from the disc (12). The records are stored distributed over different fragments (F) on the disc (12), with gaps between records in the fragments, grouping said respective subsets of the records and/or fields from the records. The subsets are stored on the disc (12) positioned so that substantially each subset extends over a minimum number of contiguous fragments that is achievable for the size of the subset.

摘要： The present invention provides a disc player that authenticates a disc via the Internet. According to one embodiment of the invention, upon insertion of a disc into a player, the player reads a disc identification (ID) on the disc. The player then sends a registration request with the disc ID to a server over the Internet for obtaining an authentication key for playing the disc, upon proper registration of the disc by the server. To properly register the disc, the server first determines whether the disc ID is included in its database. Upon proper registration of the disc, the server will set a registration status associated with the disc to prevent any subsequent unauthorized registrations for the same disc. Thus, by using the present invention, unauthorized copying of the disc can be effectively eliminated.
摘要翻译：本发明提供一种通过因特网认证光盘的光盘播放器。根据本发明的一个实施例，当将盘插入播放器时，播放器读取盘上的盘标识（ID）。然后播放器通过因特网向服务器发送具有盘ID的注册请求，以便在由服务器正确注册光盘时获得用于播放光盘的认证密钥。要正确注册光盘，服务器首先确定光盘ID是否包含在其数据库中。在光盘正确注册后，服务器将设置与光盘关联的注册状态，以防止对同一光盘的任何后续未经授权的注册。因此，通过使用本发明，可以有效地消除盘的非法复制。

摘要： Disclosed is a method of creating video object units (VOBU) in high-definition DVD (HD-DVD) systems. HD enhanced data in the form of data packets are multiplexed and stored with standard-definition (SD) data in a VOBU. In the VOBU, the spa ce where the video pocket (V-PCK) and the for SD data related video packet (V-P CK-HD) for HD-enhanced data are stored is shortened as possible. This will increase the efficiency of a future enhanced DVD video player that supports the HD-DVD optical disc format to fetch, decode and synchronize the SD and HD enhanced data. Furthermore, the optical disc created in this kind of data storing has good backward compatibility.
摘要翻译：公开了一种在高分辨率DVD（HD-DVD）系统中创建视频对象单元（VOBU）的方法。数据包形式的HD增强数据被复用并与标准清晰度（SD）数据一起存储在VOBU中。在VOBU中，存储用于HD增强数据的视频口袋（V-PCK）和用于SD数据相关视频包（V-P CK-HD）的spa ce可能被缩短。这将提高支持HD-DVD光盘格式的未来增强型DVD视频播放器的效率，以获取，解码和同步SD和HD增强数据。此外，在这种数据存储中创建的光盘具有良好的向后兼容性。
