A method and apparatus analyzes and annotates a technical talk typically illustrated with overhead slides, wherein the slides are recorded in a video sequence. The video sequence is condensed and digested into key video frames adaptable for annotation to time and audio sequence. The system comprises a recorder for recording a technical talk as a sequential set of video image frames. A stabilizing processor segregates the video image frames into a plurality of associated subsets each corresponding to a distinct slide displayed at the talk and for median filtering of the subsets for generating a key frame representative of each of the subsets. A comparator compares the key frame with the associated subsets to identify differences between the key frame and the associates subset which comprise nuisances and affordances. A gesture recognizer locates, tracks and recognizes gestures occurring in the subset as gesture affordances and identifies a gesture video frame representative of the gesture affordance. An integrator compiles the key frames and gesture video frames as a digest of the video image frames which can also be annotated with the time and audio sequence.

The bus controller may further adjust usage of the bus in response to the power conservation information provided by the power control device. The bus may be a time division, multiple access (TDMA) bus. The bus controller may enable data transfers on the TDMA bus only during assigned time slots of assigned frequency and assigned length. The bus controller may also further adjust assignment of the TDMA bus in response to the power conservation information.
