Abstract: Embodiments are directed to techniques for interacting with a hierarchical video segmentation using a video timeline. In some embodiments, the finest level of a hierarchical segmentation identifies the smallest interaction unit of a video—semantically defined video segments of unequal duration called clip atoms, and higher levels cluster the clip atoms into coarser sets of video segments. A presented video timeline is segmented based on one of the levels, and one or more segments are selected through interactions with the video timeline. For example, a click or tap on a video segment or a drag operation dragging along the timeline snaps selection boundaries to corresponding segment boundaries defined by the level. Navigating to a different level of the hierarchy transforms the selection into coarser or finer video segments defined by the level. Any operation can be performed on selected video segments, including playing back, trimming, or editing.

Abstract: A semiconductor device includes a read/write control circuit, a core circuit, and a data conversion circuit. The read/write control circuit generates a read strobe signal and a read address from an internal address/command signal based on an internal read command during a self-write operation, generates a write strobe signal after the read strobe signal is generated, and generates a write address from the internal address/command signal. The core circuit is synchronized with the read strobe signal to output read data stored in a bank selected by the read address and is synchronized with the write strobe signal to store write data into the bank or another bank which is selected by the write address. The data conversion circuit changes a pattern of the read data to generate the write data.
