This document presents the video data set that has been recently collected within the FP7 APIDIS project [1]. The acquisition setting was deployed around a basket-ball court, and consists in a set of 7 calibrated IP cameras, each one collecting 2 Mpixels frames at a rate higher than 20 frames/sec. After an approximate temporal synchronization of the video streams and the definition of an homography to link the ground points in every views, the video data have been augmented through the definition and collection of metadata. Those metadata are expected to support efficient browsing of the content, and automatic personalized summarization of the event captured by the distributed set of cameras. Metadata include (1) low-level feature distributions, (2) object trajectories, and (3) events of interest attributes. The data and metadata are publicly available upon email request to the APIDIS partners.
