Abstract: When a camera (10) turns in the reverse rotational direction toward a preset position, the camera (10) additionally turns in the reverse rotational direction by the number of offset pulses and then further turns in the forward rotational direction by the number of offset pulses. While the camera (10) turns in the forward rotational direction and the reverse rotational direction by the number of offset pulses, an image cutout unit (15) outputs image data corresponding to an area whose position in a photographing range of the camera (10) is moved in a direction of canceling the movement linked with the turning of the camera (10).

Abstract: Each of a plurality of digital video transmitting devices 100-1 and 100-2 is provided with an IEEE802.3 PHY unit 104 for transmitting video data via a digital network based on the IEEE802.3 standards. A digital video receiving device 200 is provided with a plurality of IEEE802.3 PHY units 201-1 and 201-2 for receiving the video data from the plurality of digital video transmitting devices 100-1 and 100-2 respectively. The IEEE802.3 PHY units 104 of the digital video transmitting devices 100-1 and 100-2 are connected to the IEEE802.3 PHY units 201-1 and 201-2 of the digital video receiving device 200 respectively via an IEEE802.3 network cable.
