A system and method for the capture and storage of data relating to the movements of objects, in a specified area and enables this data to be displayed in a graphically meaningful and useful manner. Video data is collected and video metadata is generated relating to objects (persons) appearing in the video data and their movements over time. The movements of the objects are then analyzed to detect the movements within a region of interest. This detection of movement allows a user, such as a manager of a store, to make informed decisions as to the infrastructure and operation of the store. One detection method relates to the number of people that are present in a region of interest for a specified time period. A second detection method relates to the number of people that remain or dwell in a particular area for a particular time period. A third detection method determines the flow of people and the direction they take within a region of interest. A fourth detection method relates to the number of people that enter a certain area by crossing a virtual line, a tripwire.

Set top boxes are provided with access to full EIT data streams without having to off-tune from one transport to another. If off-tuning is required, however, a locking mechanism substantially reduces or eliminates service interruption. Data in the additional EIT data streams in the non-home transports is reorganized to be sent by time rather than by service. EIT data is stored in the set top box in an architecture which significantly reduces the redundancy inherent in EIT data, allowing a full 7 days of EIT data to be stored in the set top box memory. The set top box of the present invention is backward compatible with conventional set top boxes.

A mail server extracts a character unregistered in a portable terminal from received mail data and affixes the font data of the character concerned to the mail data or inserts a reading tag indicating the reading (pronunciation) of the character concerned into the mail data. The portable terminal additionally registers the font data affixed to the mail data into a font database before the received mail data are displayed. Furthermore, in the display processing of the mail data, a character for which the corresponding font data is unregistered is replaced by a no-font symbol and then displayed. Furthermore, the font of each character constituting the reading tag is read out and this font is displayed subsequently to the no-font symbol.
