In this paper, we present a novel approach for higher level semantic video archival and retrieval based on symbolic representation. Topological triangular spatial relationship has been introduced to study the higher level relationship (spatial and topological) among the objects in a frame. A two dimensional time series representation to preserve the variations in relationship among objects across frames is also proposed. A modification is recommended to make Dynamic Time Wrapping (DTW) suit for matching and retrieval of symbolic videos. To corroborate the efficacy of the proposed method an experimentation has been carried out on sports videos and results are encouraging.
