摘要： Methods and systems are provided for analyzing parallelism of program code. According to a method, the sequential execution of the program code is simulated so as to trace the execution procedure of the program code, and parallelism of the program code is analyzed based on the result of the trace to the execution procedure of the program code. Execution information of the program code is collected by simulating the sequential execution of the program code, and parallelism of the program code is analyzed based on the collected execution information, so as to allow programmers to perform parallel task partitioning of the program code with respect to a multi-core architecture more effectively, thus increasing the efficiency of parallel software development.

摘要： The present invention provides a method of distributing content to a plurality of clients. The method on a server begins with accessing content to be distributed to a plurality of clients and identifying a first type of content to be distributed as crucial content and identifying a second type of content to be distributed as non-crucial content. The crucial content is any content required to properly render, after a decryption process, the content. The non-crucial content is all the other content to be distributed. The crucial content is encrypted with a first encrypting key which is unique to each of the plurality of clients. The crucial content which has been encrypted is transmitted. The non-crucial content is transmitted to the plurality of clients.
摘要翻译：本发明提供一种向多个客户端分发内容的方法。服务器上的方法开始于访问要分发到多个客户端的内容，并且识别要作为关键内容分发的第一类型的内容，并且识别要作为非关键内容分发的第二类型的内容。关键内容是在解密过程之后正确呈现内容所需的任何内容。非关键内容是要分发的其他内容。关键内容使用对于多个客户端中的每一个唯一的第一加密密钥进行加密。发送已经加密的关键内容。非关键内容被发送到多个客户端。

摘要： A scalable layered video coding scheme that encodes video data frames into multiple layers, including a base layer of comparatively low quality video and multiple enhancement layers of increasingly higher quality video, adds error resilience to the enhancement layer. Unique resynchronization marks are inserted into the enhancement layer bitstream in headers associated with each video packet, headers associated with each bit plane, and headers associated with each video-of-plane (VOP) segment. Following transmission of the enhancement layer bitstream, the decoder tries to detect errors in the packets. Upon detection, the decoder seeks forward in the bitstream for the next known resynchronization mark. Once this mark is found, the decoder is able to begin decoding the next video packet. With the addition of many resynchronization marks within each frame, the decoder can recover very quickly and with minimal data loss in the event of a packet loss or channel error in the received enhancement layer i bitstream. The video coding scheme also facilitates redundant encoding of header information from the higher-level VOP header down into lower level bit plane headers and video packet headers. Header extension codes are added to the bit plane and video packet headers to identify whether the redundant data is included.
