    摘要: A video/image encoding/decoding system based on spatial prediction, in which at least one spatial prediciton mode is used to predict for encoding or decoding. At least one prediction mode acts on at least one pixel in the region to be encoded or decoded to generate the predictive values, using a prediction filter based on one or more reference pixels; furthermore, at least one of the spatial prediction modes has one or a combination of the following characteristics: the prediction filter which is content adaptively calculated through maximizing or minimizing the optimization objective in a specific region is used to generate the predictive values. The information of at least one spatial prediction filter of a specific spatial prediction mode is coded and written into the bit stream. The encoding/decoding system of this disclosure can better capture the dynamics of different video and image contents with improved precision of spatial prediction, and better coding performance is achieved.

    摘要: The present invention provides a method of trimming traffic in an e-MBMS system and BM-SC for implementing the method. The method comprises: determining, by a BM-SC, an ABBR of the multiplexing; allocating, by an MCE, resources based on the determined ABBR; determining, by the BM-SC, whether data amount to be transmitted in a synchronization period exceeds resources allocated in the synchronization period; and dropping, by the BM-SC, tail data packets that cannot be sent in the synchronization period in the multiplexed service if it is determined to exceed. Further, the method also comprises; before the step of determining, voluntarily dropping, by the BM-SC, some data packets in the multiplexed service.

    摘要: An improved system and method for flexible object placement and soft-state indexing of objects in a distributed object store is provided. A distributed object store may be provided by a large number of system nodes operably coupled to a network. A system node provided may include an access module for communicating with a client, an index module for building an index of a replicated data object, a data module for storing a data object on a computer readable medium, and a membership and routing module for detecting the configuration of operable nodes in the distributed system. Upon failure of an index node, the failure may be detected at other nodes, including those nodes that store the replicas of the object. These nodes may then send new index rebuilding requests to a different node that may rebuild the index for servicing any access request to the object.

    摘要: A method and system for identifying a configuration parameter of a “sick” computer system that is at fault for causing an undesired behavior based on analysis of configuration parameters from other computer systems is provided. In one embodiment, a troubleshooting system collects “suspect” values for “suspect” configuration parameters used by a “sick” application when the undesired behavior was exhibited by the sick computer system. The troubleshooting system then compares the suspect values to sample values of the suspect configuration parameters retrieved from sample computer systems. The troubleshooting system uses that comparison to identify one or more suspect configuration parameters that are likely at fault for causing the application to exhibit the undesired behavior.
