摘要： Various embodiments are directed towards enabling data writes utilizing a node cache and a logstore stored on a stable storage device. A client device may send data to a node for writing to a parent file. The node may cache the received data prior to writing the data to the parent file. Caching the received data may comprise adding the received data to a node cache and to a logstore. In one embodiment, the node cache may include a coalescer that combines data from a plurality of data writes from the client device to the node prior to writing to the parent file. In some embodiments, the logstore may be mirrored logstore on one or more stable storage devices. The parent file may periodically be updated from the node cache data. After the parent file is updated, the node cache data and the logstore data may be purged.

摘要： A system and method for producing and using a protected optical media is described. One feature provides for a compact disc containing digital rights management protection to prevent unauthorized copying of copyrighted materials. Another feature provides for secure copying, storage, transfer, and playback of digital audio content from a protected compact disc or computer storage. Yet another feature provides for a versatile optical media that can be used in both traditional audio compact disc players and in computer CD-ROM drives without risking the security of the content on the media or preventing purchasers from having a robust content experience.

摘要： The invention is related to methods and apparatus for tailoring an amount of Pre-Data that can be used in media clip streaming applications. A variable-bit-rate encoded media clip can be encoded at an average playback bit rate. When the actual transmission bit rate exceeds the average playback bit rate, a maximum bit deficit computation that uses the average playback bit rate overestimates the amount of Pre-Data that can be used to buffer the media clip. Embodiments of the invention tailor the amount of Pre-Data at least in part to the amount of data used to encode intervals of data and to actual transmission bit rates or to predictions of actual transmission bit rates, thereby decreasing the amount of Pre-Data that can be used and decreasing a latency time before play of the media clip begins.

摘要： A number of digital content rendering modules are equipped such that selective subsets of the modules may be employed to render digital content of different media, and of different format types. The modules are organized into a hierarchy, with a selected one occupying a root position of the hierarchy, to exclusively receive the digital contents to be rendered, and that each module is further responsible for verifying the integrity of its immediate downstream modules, to collectively protect the digital contents being rendered. Additionally, in accordance with another aspect, a tamper resistant module is employed to recover digital contents provided in a protected state, obfuscating the recovery. Further, the modules may be of different application domains.
