ASC Lecture Object Survey Summary George Brett April 2005 George Brett April 2005

2 Survey Introduction For purposes of this survey, the Lecture Object is defined as a digital object composed of lecture video, audio, support graphics, slides, with important metadata about the contents. In simple terms this includes audio/video of a speaker merged with synchronized presentation materials, typically PowerPoint and has additional metadata/information attached to support searching an archive of Lecture Objects. Some part of almost every Internet2 member institution is actively capturing Lecture Objects for storage, retrieval and playback today. But each in its own way. The lack of widely accepted approaches to capture, post-production, storage, indexing, retrieval or playback means not only that work is being duplicated unnecessarily, but that our shared community of users has no easy way to find and play back Lecture Objects from other places other than by doing individual searches and using a variety of playback tools that have differing network and platform requirements. The Internet2 Lecture Object project seeks to first understand current practices by members of our community, and will then evaluate the promulgation of standard frameworks for the capture, production, storage, retrieval and playback of Lecture Objects. Findings will be shared with the Internet2 members. We appreciate your assistance in collecting information about your organization's use and interest in Lecture Objects.
