Abstract: An information display device includes an input interface that accepts an input manipulation including setting a starting location and a destination, and a processor that displays in a display area, an object and a manipulator for use to enter an instruction to change the display state of the object. The processor changes the display state in accordance with a vector to be defined by the distance and direction from the starting location to the destination. The processor performs a first type of processing in response to the input manipulation done on a region other than a region of the manipulator, and a second type of processing of changing the display state in response to the input manipulation done on the region of the manipulator. In the second type of processing, the display state of the object can be changed more finely than in the first type of processing.

Abstract: A supervisor can ascertain an occurrence of a congestion state in advance by performing an appropriate notification prior to reaching the congestion state. There is provided an area setting unit that sets at least two determination areas on the captured image in response to an input operation of a user, a person sensor that senses a person existing within the determination area from the captured image, a congestion degree calculator that calculates a congestion degree for each of the determination areas based on a sensing result by the person sensor, a state sensor that compares the congestion degree calculated by the congestion degree calculator with predetermined reference values for each of the determination areas, and senses a plurality of states including a congestion state and a potential congestion state, and an output unit that outputs information for performing a notification action based on the sensing result by the state sensor.

Abstract: A stream input unit (102) receives a transport stream. A subtitle information extracting unit (104) separates the received transport stream into subtitle information and information other than the subtitle information. Next, a stream format converting unit (105) converts separated video/audio information contained in the transport stream into a program stream of video/audio. A subtitle format converting unit (107) converts the subtitle information separated by the subtitle information extracting unit (104) into a program stream of subtitle information. Thereafter, a subtitle information inserting unit (108) inserts the subtitle information converted by the subtitle format converting unit (107) into the program stream converted by the stream format converting unit (105), and outputs the resultant program stream.
