Abstract: In one embodiment, a method of streaming media includes partitioning a media stream to be transmitted into a first stream of media segments at a media server. The first stream of the media segments has a first sequence. An index table is generated to identify the first sequence of the first stream of the media segments. The index table is encrypted using a key. A second stream of the media segments is generated. The second stream has a second sequence, which is random relative to the first sequence. The encrypted index table and a transcoded media stream having the second stream of the media segments are transmitted.

Abstract: Oxazolidinium compounds are formed by the reaction of a halohydrin or an epoxide with a secondary amine and an aldehyde or a ketone. The oxazolidinium compounds are formed directly and do not require the reaction of a pre-formed oxazolidine with an alkylating agent. The compounds are useful as gas hydrate inhibitors in oil and gas production and transportation.

Abstract: Reversible watermarking methods enable auxiliary data to be embedded in data sets, such as images, audio, video and software. The reversible nature of the method enables the original data set to be perfectly restored. Control systems with feedback loops are used to optimize embedding based on distortion or auxiliary data capacity constraints. The watermarking may be applied recursively to embed several layers, where subsequent layers are embedded into a previously watermarked data set. To recover the original data, each layer is extracted and the data restored in reverse order of the embedding. Sets of elements that are expanded to carry auxiliary data in each layer overlap or are interleaved to maximize embedding capacity or quality of the host data.
