This paper presents a method for automatic structural analysis of digital videos to generate the table of content and the index table of the given videos.These tables allow storing videos by a hierarchy of video, cluster of shots, shots, key-frames of shots, cluster of regions. Then a method for retrieving videos by using the input data as visual feature and semantic concepts is represented.

Using the analytic hierarchy process (AHP) method for multi-index evaluation has special advantages, while the use of geographic information systems (GIS) is suitable for spatial analysis. Combining AHP with GIS provides an effective approach for studies of mineral potential mapping evaluation. Selection of potential areas for exploration is a complex process in which many diverse criteria are to be considered.

Objectives: Describe how a hierarchical network supports the voice, and data needs of a small- or medium-sized business. Describe the functions of each of the three levels of the hierarchical network design model, the principles of hierarchical network design (aggregate connectivity, network diameter, and redundancy), and the concept of a converged network. Provide examples of how voice and video over IP affect network design. Select appropriate devices to operate at each level of the hierarchy, including voice and video components.

Principle of Locality: Programs access a small proportion of their address space at any time. Temporal locality: Items accessed recently are likely to be accessed again soon, e.g., instructions in a loop, induction variables. Spatial locality: Items near those accessed recently are likely to be accessed soon, E.g., sequential instruction access, array data.
