	abstract = {Cinema industry has chosen Digital Cinema Package (DCP) as encod- ing format for the distribution of digital films. DCP uses JPEG2000 for video compression. An efficient implementation of coding and decoding for this format is complex, however. Currently deployed equipment is expensive and has high maintenance costs, preventing art-house cinema theaters from acquiring it. Therefore, we conduct this research activity in cooperation with Utopia cinemas, a group of art-house cinemas, whose main requirement (besides functional ones) is to provide Free and Open Source Software (FOSS). This paper presents a solution that achieves real-time JPEG2000 decoding and DCP presentation based on widespread open source multimedia tools, namely VLC and libavcodec library. We present the improvements that were made in VLC to support the DCP packaging format, as well as details on JPEG2000 decoding inside libavcodec (optimization and lossy decoding). We also evaluate the performance of the decoding chain.\&nbsp;},

	abstract = {High-resolution panoramic video with a wide field-of-view is popular in many contexts. However, in many examples, like surveillance and sports, it is often desirable to zoom and pan into the generated video. A challenge in this respect is real-time support, but in this demo, we present an end-to-end real-time panorama system with interactive zoom and panning. Our system installed at Alfheim stadium, a Norwegian premier league soccer team, generates a cylindrical panorama from five 2K cameras live where the perspective is corrected in real-time when presented to the client. This gives a better and more natural zoom compared to existing systems using perspective panoramas and zoom operations using plain crop. Our experimental results indicate that virtual views can be generated far below the frame-rate threshold, i.e., on a GPU, the processing requirement per frame is about 10\~milliseconds. The proposed demo lets participants interactively zoom and pan into stored panorama videos generated at Alfheim stadium and from a live 2-camera array on-site.},

	abstract = {This paper is published in a French translation. Cinema theaters have arrived in the digital era. For the distribution of digital films, the Digital Cinema Initiative (DCI) has chosen Digital Cinema Package (DCP) as encoding format for feature films. This activity is made with Utopia cinemas, a network of independent theaters. The main requirement from Utopia is to provide free and open source software for digital cinema. DCP uses JPEG2000 for video compression because of its high compression rate of large images. An efficient implementation of coding and decoding for this format is complex, however, we focus on an improved implementation of the decoding part to support the projection side in digital cinemas. Our reason is that equipment that is currently deployed in movie theaters is expensive and has a high maintenance cost, preventing small and independent theaters from deploying it. We intend to provide software solution to playback DCPs adapted to arthouse. This paper presents a solution that achieves real-time decoding and presentation based on widespread open source multimedia tools as VLC player and the libav/ffmpeg libraries. We present the improvements that were made in VLC to support DCP, which include reading files from disk and synchronizing audio and video. Then the description of the JPEG2000 decoder inside libav/ffmpeg is detailed, and finally playback performances evaluations are presented.},
