An in-vivo sensing system and a method for creating a summarized graphical presentation of a data stream captured in-vivo. The graphical presentation may be in the form of for example a color bar. The color bar may be a fixed display along side a streaming display of the data stream. A cursor or other indicator may move along the fixed color bar as the data stream is displayed and/or streamed so as to indicate to a health professional what part of the data stream may be currently displayed. The color content in the color bar may map out the data stream and give indication of the location of anatomical sites as well as possible locations of pathology.
