Map topology for navigating a sequence of multimedia

A multimedia content delivering system for information retrieval on usage of a specific feature of a specific product from a sequence of multimedia files based on a map topology from an application server comprising a processor, an input means, a display, and a memory that stores a pre-indexed database that comprises a sequence of multimedia files, each multimedia file demonstrating at least a feature of a product, said system comprising;

• a map module that generates a map topology comprising (a) a first branch comprising a first sub-branch that comprises a beginner level video demonstrating a feature of said product, (b) a second branch comprising a second sub-branch that comprises an intermediate level video demonstrating said feature of said product, and (c) a third branch comprising a third sub-branch that comprises an advanced level video demonstrating said feature of said product;
• and
• a video provider module that
• (i) displays an icon of a selected video from said beginner level video or said intermediate level video or said advanced level video based on a selection of said first sub-branch or said second sub-branch or said third sub-branch;
• (ii) displays, for said selected video, steps in association with assembly or operation of said product adjacent to said selected video at said display unit, wherein said selected video comprises a plurality of video segments, wherein each of said video segments (i) demonstrates at least one step related to said feature of said product and (ii) has an associated timestamp, wherein each of said steps in association with assembly or operation of said product has an associated timestamp;
• (iii) processes a selection of a specific step from said steps in association with assembly or operation of said product;
• (iv) identifies a specific video segment, from said plurality of video segments, that corresponds to said specific step by detecting a video segment having a timestamp that corresponds to a timestamp of said specific step;
• and
• (v) plays said specific video segment corresponding to said specific step in association with assembly or operation of said product from said timestamp associated with said specific video segment or said specific step.
