An information processing system includes an electronic apparatus, a server, and an external apparatus. The electronic apparatus acquires operation information for the electronic apparatus from the server, and directs the electronic apparatus to operate according to the operation information. The server receives an external apparatus identifier, electronic apparatus identifier, and operation information, from the external apparatus, and accumulates the information. The external apparatus accepts input of the electronic apparatus identifier and the operation information, and transmits the external apparatus identifier and the operation information to the server. Such an information processing system enables operation information for an electronic apparatus to be set and acquired, without directly accessing an electronic apparatus from an external apparatus, improving security.

The present invention discloses a structure which uses a communication system which comprises a communication initialization apparatus and communication terminals, such as an air conditioner and a humidifier, which mutually communicate with each other through a network. In the system, the communication initialization apparatus updates installation place information at predetermined timing and checks states of addresses of the communication terminals based on setting-regarding information which consists of the addresses of the communication terminals and equipment type information, whereby initial communication setting is updated. This allows communication between the communication terminals even when a communication terminal to communicate with is changed.

A communicative control system includes a central control apparatus and a terminal that is remotely controlled according to messages communicated by the central control apparatus . Before communication is commenced, the address storing unit of the terminal stores a provisional address, while the unique terminal information storing unit stores unique terminal information. When commencing communication, the central control apparatus uses the provisional address to specify the terminal with which communication is to be performed. The central control apparatus compares the unique terminal information stored in the unique terminal information storing unit in the terminal with the unique terminal information that is stored in advance in the unique terminal information storing unit and is associated with a proper address stored in the address storing unit . Depending on the result of the comparison, the central control apparatus then has a corresponding proper address stored in the address storing unit of the terminal

An MPU 1 decomposes video-audio information which is externally inputted and stored into a second temporary storage area 32 for each parameter included in a sequence layer and the like, and further into video information and audio information, and stores the information into a third temporary storage area 33. Next, the MPU 1 extracts a predetermined quality deterioration parameter from the parameters stored in the third temporary storage area 33 and stores a prescribed value in the storage area in which that quality deteriaration parameter was stored. The MPU 1 then composes the video-audio information stored in the third temporary storage area 33 again and stores the composed video-audio information (quality deteriorated) into a fourth temporary storage area 34. Next, the MPU 1 outputs the video-audio information (quality deteriorated) stored in the fourth temporary storage area 34 to a first recording device 4 and causes the first recording device 4 to write the video-audio information (quality deteriorated) on a copy target recording medium 4. Thus the size of the display screen of the video-audio information (quality deteriorated) differs from that of the video-audio information externally inputted.

A communication protocol can communicate data among apparatus by a simple procedure efficiently. In an AV center (1) (D2B control unit (1a), for example, a communication mode thereof is set in the master transmission mode, and a packet of one frame is transmitted to a TV (2). In the TV 2 (D2B control unit (2a)), its communication mode is set in the slave reception mode. When a packet of one frame from the AV center (1) is received by the TV (2), a communication between the AV center (1) and the TV (2) is ended.

Lens control apparatus for use in a video camera in which an object is imaged through an adjustable lens onto an image pick-up element from which a video signal is derived. The lens is driven for focus or zoom adjustments by servo control at a rate determined by the synchronizing signal included in the video signal. The aperture of the video camera also is controlled by detecting the amount of light which impinges on the image pickup element and then determining the ratio between the detected light level and a reference level representing the brightness of the object. The aperture is driven (i.e. it is enlarged or reduced) as a function of the product of the aforementioned ration and a coefficient which changes with the aperture opening. When the aforementioned ratio is less than unity, the coefficient increases as the aperture opening decreases and, conversely, decreases as the opening increases. When the ratio is greater than unity, the coefficient increases as the aperture opening increases and, conversely, decreases as the opening decreases.
