There are large amounts of information as video and audio not searchable. In a time where Business Intelligence is fundamental for all areas doing this kind of analysis only on text sources is a limiting factor. The use of large vocabulary speech recognition systems with increasing performance is giving rise to different applications. Despite the diversity, these applications share the extensive use of the contents of the transcription. In this paper we describe the results of a development project between a startup company and a research lab to build a full automatic system for monitoring TV and Radio channels. This system is composed by three main blocks: a recording block (records the selected channels in high and web streaming quality and broadcast to the next block), a processing block (generate metadata information) and a storage and accessing block (make available the metadata and videos). There is an optional block, the delivering, that could be customized according to the use and client needs. The processing block receives the video from the recording block time filtered by a scheduling interface. For that video the goal is to generate a full annotation with metadata describing the content and semantic information. This metadata make possible a filtering process for selective dissemination of information.
