....(TV3 and Channel 4 in Fschlr) do not use black, silent frames to flag ad breaks. Therefore some additional characteristics of advertisements need to be utilised. In order to maximise the visual impact of TV advertisements, producers frequently use a faster rate of shot cuts than normal TV content [3]. The use of shot cut rate for locating ad breaks is detailed in Section 4 and results are given in Section 5. 2.

....of shot cuts is often increased to maximise the visual impact of ads. This observation has been also noted by researchers on the Informedia Digital Library project who reported that the rate of shot cuts for an advertisement rises above 1. 7 times the mean rate of shot cuts for the whole program [3]. The average rate of shot cuts over three entire MPEG video files containing ad breaks was calculated and the results are tabulated in Table 3. Name of MPEG file Shot Length Average Rate of Shot cuts(Hz) Good Morning Vietnam 90.09 frames 0.27777 Free Willy 67.08 frames 0.37268 Thelma and Louise ....

....such as flashes, which cause a sudden change on a single frame where no shot change is actually taking place. In many cases shot boundaries are not the most logical divisions for example in news broadcasts it is per haps more useful to segment on story boundaries. Hauptmann and Witbrock [7] have suggested the integration of information from subtitles, speech recognition transcripts and the video stream itself to determine story boundaries. However, since our aim is to obtain enough salient key frames for effective retrieval, it is necessary for us to segment the video into its most ....

....division. For example, in the case of a film, it may be more desirable to divide the recording into scenes, where a scene is a series of consecutive shots at a single location. For news broadcasts, it is perhaps more logical to divide the programme into sepa rate stories. Hauptmann and Witbrock [5] have suggested the integration of information from subtitles, speech recognition transcripts and the video stream itself to determine story boundaries. An algorithm based on that proposed by Pye et al. [6] at AT T Labo ratories has been implemented. The algorithm makes use of the soundtrack that ....

Hauptmann et al. [9] suggested integration of various sources of informa tion to determine if a story boundary had occurred in news video. They looked at various image features to see if a commercial break had occurred, they used information from the audio track (longer silences indicated significant changes) and ....

The rate of shot changes together with the presence of black frames is used in [34] to detect commercials within news broadcast. The rationale behind detection of black frames is that they are often broadcasted for a fraction of a second before, after, and between commercials. However, black frames can also occur for other reasons. Therefore, the authors use the observation that ....

Different methods have been proposed in the literature for video program classification into predefined categories such as a commercial detection system (Hauptman and Witbrock, 1998). One successful study carrying out video classification was performed using a domain method relying on nearest neighbor clustering (Wei et al. 2000) The positive aspect of this classification method is its simplicity. Each decision made in the process corresponds to a certain aspect of human ....

Different methods have been proposed in the literature for video program classification into predefined categories such as a commercial detection system [1] and a rule based basketball video indexing system [2] However, like most other research work on video classification, advantage was not taken of temporal features in video, a very powerful cue in understanding video content. Therefore we explore the use of hidden Markov models (HMM) for video ....

This generally involves generating a transcription and performing the segmentation using text based methods (e.g. van Mulbregt et al. 1999) but it is also possible to use additional audio or video cues (e.g. (Hauptmann and Witbrock, 1998)) This paper describes experiments on a system which uses both ideas, exploiting properties of the audio to impose some structure on complete broadcasts, whilst using windowing techniques to find relevant passages during retrieval.

Instead, we can carried out semantic segmentation using multimedia cues which return requested information that is long enough to be informative and as short as possible to avoid irrelevant information [2] [3]. Some work on this issue had been carried out, by using a single medium (visual or text) or integrated the cues from different media. Some existing approaches make use of fixed textual phrases or exploit the known format of closed captions. Phrases like still to come on the news and other known ....

Different methods are proposed in the literature for video program classification into predefined categories or detect specific categories of programs like the commercial detection system presented in [5] and [8] We explored the use of face and text tracking for video classification. This stems from the fact that most TV programs focus on human activities and human faces play a very important role in the same. In most occasions video content can be satisfactorily characterized by capturing face ....

These story boundaries were initially added manually to the documentary footage. Subsequent experiments have looked at generating story boundaries automatically [7].

Alternate representations of the video are automatically generated to enable the user to quickly decide which video segments are worth further inspection [2] ....
