....News programme can then be presented to a user as a storyboard of keyframes, either the full set of keyframes (perhaps 200 250 such keyframes per broadcast) or an abstracted subset of 20 or 30. To support user browsing through these keyframes we have developed several keyframe browser interfaces [10] from which the user can choose. To compliment the keyframe browsing facilities in Fschlr, we have developed a text based search tool for video digital libraries. We capture the closed captions associated with 6 TV channels, 24x7 and we link these to the archived broadcast. In this way we can ....

....The most widespread type of video summarisation is based on generating keyframes from video shots and presenting these via some kind of keyframe browser interface. In Fschlr we have several keyframe browsing interfaces which allow a user to browse the several hundred keyframes from a TV program [10]. For example, a 30 minute news program may have between 300 and 400 such keyframes in one of these interface we also automatically reduce this large set to a summary of only about a dozen keyframes, one per news story. The way in which one automatically summarising video into a shorter video ....

....and stored on the system s video server. This MPEG1 video bitstream is then analysed using a set of indexing tools in order to create a visual index for the content. The visual index is presented to users in one of eight different interfaces which facilitate non linear browsing of the content [3]. In this paper, the indexing tools employed in order to create a visual index for the specific case of news programmes are described. The visual index used in Fschlar is described in the following section. The analysis tools used to instantiate this index are outlined in section 3. Some ....

....impact on performance. 3.2 Dublin City University (Ireland) The group from Dublin City University explored interactive search and retrieval from digital video by employing more than 30 users to perform the search tasks under controlled, timed conditions. In the Fschlr system developed at DCU [5], several keyframe browser interfaces have been developed and the task DCU performed was to evaluate the relative effectiveness of three different keyframe browsers. One of these keyframe browsers was based on a timeline of groups of related keyframes, a second browser interface simply played the ....

....in Figure 2. 4. BROWSING INTERFACES Various features of video querying and browsing interfaces are introduced and categorised in [9] The particular design methodology we employed in developing a selection of keyframe based video browsing interfaces for Fschlar is discussed in detail in [10]. As such, in this section we simply present a high level overview of the interfaces we have developed. In the scroll bar browser, the user simply scrolls up and down through all available keyframes which are arranged left to right, top to bottom in order of increasing temporal location in the ....

The user has a choice of five content browsers overview detail, slide show, scrollbar, dynamic overview and hierarchical browser [7]. The overview detail browser displays an overview page and also allows browsing of all the keyframes in pages of 24 images. The scrollbar browser lists all the keyframes on a single page. The slideshow browser lets the user flip through the keyframes one at a time. The dynamic overview browser ....

....and WAP applications for TV programme notification, alerting, recording request, etc. 2. USER INTERFACE FRAMEWORK To be able to design and provide many alternative browsing interfaces to users, we have developed an interface design framework for keyframe browsing (full details can be found in [Lee 00b] which we later use to design interfaces for handheld devices. In summary, by analysing the essential elements of keyframe browsing interfaces, we came up with three dimensions and possible values for each dimension: 1) Layeredness consideration about different details or granularity of ....

....video requiring more of a search browse interaction than for text based information retrieval. Once we have narrowed the library or collection of video to a unit of the order of size of a programme, the task then becomes browsing within this programme in order to find segments of interest. In [18] we present a framework for the development of browsing interfaces to video. Two of the most interesting ones which illustrate different approaches are shown in Figures 2 and 3 Fig. 2. Screendump from Fschlr showing keyframes taken from the middle of a 30 minute News and Weather broadcast. In ....
