To illustrate the benefits of the BUSMAN system, some expected application scenarios are summarised below.
Extract from BUSMAN user scenario - "football fans"
Mike is on a train to Leeds to meet up with some friends for the weekend. As the journey will take a number of hours he decides to use his BUSMAN application to browse the video collection of football games that have been played over the years by the team he supports - Manchester United - thinking that he might watch one of their more memorable matches during the journey. He remembers the time when they played Ipswich and beat them 9-0. He enters his team name, the opponent's team name and the score of the match, and the BUSMAN system retrieves the video of that match. Mike pays for one viewing, sets up his display screen on its stand and settles down to watch the match.
On reaching Leeds, Mike goes to his friend's house where they spend the afternoon watching football on TV. They watch Manchester United play Liverpool, Manchester win 3-2 with one particularly good goal by Roy Keane through an overhead kick. Liverpool have one goal disallowed following an off-side decision.
They head out for the evening, starting off by meeting more of their friends at a local pub. Discussion about the match that day ensues and they decide to watch highlights of Manchester's goals. Using BUSMAN they enter the team names and the date of play, and choose to see the 'goal highlights' video for Manchester that is available. They watch the build up, goal and celebration, with the fans following each of the goals. A dispute arises about the disallowed goal. A video clip of this goal is passed around amongst the group and the particular goal is viewed a number of times by different people. The motion is slowed and rewound at the crucial moment as each person tries to decide whether the decision was right or not. Different camera angles are also selected in the search for evidence on the decision.
Extract from BUSMAN professional scenario - "Searching for the Perfect Tiger"
The creative director of a production company, Gita, is creating a commercial spot that includes "a tiger jumping into shallow water". It is not possible to shoot the scene within the budget constraints, so she uses archive material instead. In order to learn about the availability and costs of appropriate shots, Gita uses the BUSMAN system to search for options.
The first query term entered is "tiger jumping into water". The query returns keyframes of shots of tigers, of athletes, of children, some of which are playing with a tiger puppet, and swimmers jumping into water. Gita selects the ones showing tigers. Some of them look good and she clicks on them. Full screen previews let her assess what the shots look like. Yet none fits perfectly. There is one that is close and indeed shows a tiger jumping into deep water in evening light, moving towards the camera. Gita selects this shot and asks the BUSMAN system to look for "similar" shots. The system returns four groups of results, in one of which Gita finds a jaguar jumping into water, which she marks and asks the BUSMAN system to search again and find more shots similar to this. By repeated iterations using the best current match as the next search input, two candidate shots are finally selected.
The BUSMAN system is then instructed to search for the rights. Gita enters a detailed description of the intended use using the classification provided by the BUSMAN system. The system returns the rights limitations attached to the shots and the contact details of the rights holder. Contact is established with the rights holders via email to discuss details of licensing and prices.
After the contracts are signed, the BUSMAN system transfers master quality copies of the acquired shots to a download server. Download authorisation data is sent on a secure channel to Gita who uses this information to download the master quality copy to her editing equipment. After the download is complete, information that the shots have been downloaded is stored in the system and sent to the rights holders.
Other application scenarios include using embedded metadata in freely distributed video to get access to on-line meta-databases and to obtain information about other related video clips, and using BUSMAN technology to insert a DII-watermark on high quality content at the production stage which can be traced throughout postproduction and subsequent delivery channels.
