— In an H.264 video encoder, the important task of intra coding is performed in the residual domain after a spatial transform has been applied to the block data. Although the intra prediction is very efficient and shows the ability to capture some orientations of the image, after this spatial prediction the intra residual may still show regular structures.(More)
Video watermarking systems operating directly in the compressed bit stream are receiving increasing interest due to their ease of integration into existing content delivery workflows. Such algorithms, however, usually involve a strong dependency to the underlying video codec. In other words, the throughput of the system, e.g. the embedding rate, is heavily(More)
In this industrial exhibit, Technicolor will showcase various technologies developed to protect digital audio-visual material all along the media value chain, from production to distribution, including forensics services in case pirated content is detected. The exhibit will be organized around Technicolor's proprietary technologies in video fingerprinting(More)
HTTP adaptive streaming has become the dominant solution for broadband streaming delivery. Essentially, the server delivers small chunks of content in response to queries from a player, that can alternate between different qualities of content depending on its rendering capabilities and the network condition. In this paper, we highlight that the frequent(More)
Type 1 Diabetes Mellitus (T1DM) is an autoimmune disease in which the insulin-producing beta cells of the pancreas are destroyed and insulin must be injected daily to enable the body to metabolize glucose. Standard therapy for T1DM involves self-monitoring of blood glucose (SMBG) several times daily with a blood glucose meter and injecting insulin via a(More)
Content owners are reluctant to deliver premium content to open devices due to the risk of piracy and the corresponding potential for loss of revenue. To lift this deadlock, there is increasing interest in incorporating watermarking-based tracing mechanisms onto mobile devices such as smart phones and tablets. The scarcity of resources calls for innovative(More)
