Abstract
TV news channels present rich and complete experience of various events through audio-visual content. This makes television news an influential medium to affect masses and thus persuaded various social scientists and regulators to monitor and analyze the content of broadcast videos. An organized archive of newscast is a prerequisite for any such analysis. Creating such archive requires segmentation of continuous news videos into suitable logical units. Based on the application, these logical units may be one of channel content obtained after advertisement removal, different shows, news stories or video shots. In this work, we propose an end to end system with software architecture for segmenting the TV broadcast videos at all these four granularities. The videos are segmented into shots. Video shots are used as basic unit for all further processing. Video shots are first subjected to advertisement detection and removal to obtain the non-commercial channel content. This channel content is further processed to identify various program boundaries. We propose to identify three types of shows based on the presentation format viz. news bulletins, interviews and debates. News bulletins so obtained are processed further to obtain news stories. We propose a modular and scalable framework and software architecture for the broadcast segmentation system for deployment on a computation cluster. This involves scheduler based recording module and broadcast segmentation module. We have presented the detailed software architecture for individual modules, automation of entire processing pipeline along with resource and database management systems. We have implemented and verified the software architecture by deploying the proposed system on a cluster of nine desktops and one workstation. The deployed system was used for round the clock processing of three Indian English news channels.
