An information processing apparatus in which its function can be improved by installing an additional module to an existing module in a module configuration system. A video information processing apparatus, which is an existing module, has the function of reading, from a network moduleas an additional module, software held in the network module. The software held in the network moduleincludes control software for the network module and software for making the control software available to the existing video information processing apparatus. The software held in the network moduleis added to the video information processing apparatus, and the network moduleis operated by the video information processing apparatus

An optical disk physical has a recording region divided into zones, each zone including physical tracks adjacent to each other. An integer number of sectors are provided in each physical track. The angular recording density is higher in the more outward zones such that the linear recording density is substantially constant throughout the recording region, and logical tracks are formed of a predetermined number of sectors, independent of the physical tracks. The conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from a host device is easy. The addresses written in headers of the sectors in the logical track in which data are actually recorded, including substitute sectors used in place of defect sectors, are preferably consecutive to further facilitate the conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from the host device. Each of the zones can be set to serve as any of the different types of recording area independently of other zones.

Image feature values Va and Vb are derived from image data, coefficients C and D are determined based on the image feature values Va and Vb, and an approximate expression expressed with the file size Sfj of the JPEG compression file and the quantization data coefficient value Aqt is derived. Next, by designating the file size of a desired predetermined JPEG compression file based on the approximate expression, the quantization data coefficient value Aqt is derived, and a first quantization table as a reference is multiplied by the quantization data coefficient value Aqt, whereby a second quantization table is obtained. Then, using the second quantization table, the image data is actually JPEG-compressed.

An information collecting system includes at least one terminal and an application server. The application server includes a receiving section for receiving input information transmitted from the terminal to the information processing center via the network; an information processing section for deciding as to the information received, and for constructing a picture to be displayed on the terminal in response to a decision result; and a transmitting section for transmitting the picture generated by the information processing section to the terminal. The application server further comprises a differential detector for detecting a difference between the client display picture stored in a storage and a client display picture newly generated by a client display screen constructor, wherein said transmitting section transmits only differential information detected by said differential detector to said terminal.

A system for presenting information to passengers in a conveyance, has a computer which stores operation diagram information; a storage medium which stores a plurality of advertisement data items to be presented to the passengers; and an information presenting device. The computer obtains an operation time in each operation section on the basis of the operation diagram information and identification data for identifying the conveyance, and selects and arranges some of the advertisement data items to generate presentation data for continuously presenting information to the passengers throughout a time period corresponding to the operation time. The information presenting device reproduces the presentation data corresponding to each operation section to present the information to the passengers in each operation section of the conveyance.
