E.2 … In H.264/AVC, a picture (frame or _eld) is divided into slices. Each slice contains a number of macroblocks and it is usually packed into a NAL unit. An Access Unit (AU) is a set of consecutive NAL units which results in exactly one decoded picture. For the sake of simplicity, we will assume frame coding and one slice per frame, using interchangeably frame, picture, slice and access unit. Frames are also structured in Groups of Pictures (GOPs) related by temporal prediction, though frames from different GOPs can be also related by prediction.

5.7.1. Cluster level
When the length of the summary is very constrained (usually in storyboards and short skims), the algorithm focuses on covering the basic semantics of the sequence with as few GOPs as possible. We assume that clusters are a reasonably good representation of these semantics, and that each cluster can be represented by a keyframe (for storyboards) and by a short excerpt of Nexc consecutive GOPs (for video skims). Thus, finding a representative keyframe or segment for each cluster should be enough to have a suitable summary in these limited conditions. If the length of the summary is even more constrained, some keyframes or excerpts must be discarded, with an associated loss in coverage.
To provide the best set of keyframes for each summary length, clusters are ordered by their relevance, using the following iterative ranking procedure in which the clusters are ranked and selected incrementally:

With the implementation of the server, the client may not need imitation anchor modules. For example, in response to a user clicks on a particular excerpt OK, scroll to the server returns directly corresponding to the selected portion of the target document excerpts buffer pages. In one embodiment, when the user clicks on a particular row extract, search query and the specific number of lines to be extracted to the server
