Video Reports = V-Reports

The TVD system is designed to automatically index video data in a hierarchical and relational database structure.  If one is creating a video document library, based on user queries, sequences can be extracted and stored in video folders.  But for some applications it is more important to generate a single video report intended for a particular user, or viewer.  An athletic coach will want to give team-members CDs at the end of the week showing just those performances during practice which are relevant to the player. A real-estate broker will be able to send her client walk-throughs of several different homes – and the CD will include the reporting “front end” – or thrummer interface letting the potential customer compare dining rooms, staircases, basements, and garages to one another to their own satisfaction and in whatever way they choose.  It is the ability to compare-and-contrast short film segments which gives thrumming its most powerful feature as a diagnostics and analysis tool.

V-reports are possible because the thrum signal structure is designed to contain information relevant to the person making the film (the camera-person and thrummer), the meanings attached to the signals at the time the workpad was programmed and prior to its being downloaded to the thrummer.   If one considers that each thrummed metadata signal must be encoded with enough information to allow even the shortest segment to be extracted and stored as an individual video file, it becomes clearer that thrum signals must contain sufficient structure and granularity to generate a database of considerable relational structure.

In many ways sense, the choice to thrum a video is to amplify human memory and discrimination.  Its use in this way comes closer to the historical origins of film.  The Lumiere Brothers devised a system for artists to analyze motion, and not long afterwards Gilbreth (of Cheaper by the Dozen fame) used time and motion studies for earliest research in industrial engineering.

Where visual analysis is part of a job, diagnostic controls are built directly into the thrummer workpad.  You know – on-the-spot – that you want a particular sequence of moves, i.e. muscular coordination, tagged for a frame-by-frame analysis.  Similarly, you realize a player has just demonstrated their best performance of the week – which you want to classify as the “model” and baseline against which all other similar performances will be judged.  The V-report will automatically tag these segments for special types of reports, which you may or may not choose to generate. HOWEVER, the indexes will always remain in the system, and later on, you will be able to create a report comparing all of these models against one another, allowing you to recognize things about an individual’s development (or degeneration) which you might never have recognized before.
