摘要： A random access read/write media format that enables segments of media to be read, written, accessed, and streamed in a non-sequential order. A media file is divided into a series of timeblocks TB0 to TBn-1 wherein each timeblock consists of media packets of a short non-overlapping time span. Each media packet in the media file is also divided into data units identifiable by data unit ID. A timeblock index table, with an entry for each timeblock in the series, and a media packet index field with a data unit ID entry for each data unit in the media packet (located in each timeblock header), are used to quickly locate portions of desired data. This two-level index hierarchy, the timeblock index table and the media packet index table, eases the locating, reading and writing of non-sequential media packets. The timeblock index allows data to be quickly found in terms of time, while the media packet index allows data to be quickly found by data unit ID.

摘要： A DRM scheme that may be optionally invoked by the owner. With the DRM protection turned on, the media is encrypted before it is distributed in a P2P network, and is decrypted prior to its use (play back). The peers may still efficiently distribute and serve without authorization from the owner. Nevertheless, when the media is used (played back), the client node must seek proper authorization from the owner. The invention further provides a hierarchical DRM scheme wherein each packet of the media is associated with a different protection level. In the hierarchical DRM scheme of the invention there is usually an order of the protection level. As a result, in one embodiment of the invention, the decryption key of a lower protection layer is the hash of the decryption key at the higher protection level. That way, a user granted access to the high protection layer may simply hold a single license of that layer, and obtain decryption keys of that layer and below. The invention further provides for a process for managing digital rights to a scalable media file wherein a different encryption/decryption key is used to encrypt each truncatable media packet with a base layer without requiring additional storage space to store the key.

摘要： The subject disclosure is directed towards a data deduplication technology in which a hash index service's index and/or indexing operations are adaptable to balance deduplication performance savings, throughput and resource consumption. The indexing service may employ hierarchical chunking using different levels of granularity corresponding to chunk size, a sampled compact index table that contains compact signatures for less than all of the hash index's (or subspace's) hash values, and/or selective subspace indexing based on similarity of a subspace's data to another subspace's data and/or to incoming data chunks.
