A multimedia communication system which allows a user at a terminal to efficiently place an order for merchandise with a merchandise provider includes terminals and a multimedia server connected thereto via a public network. The multimedia server includes an information storage unit for storing multimedia information on each merchandise item, a communication control unit for controlling information transmission between terminals and the server via the public network, and a bulletin board service unit for transmitting merchandise items from the information storage unit to the communication control unit in response to a merchandise information look-up request from any of terminals. The multimedia server further has an ordering service unit and a main service unit. The ordering service unit enters the quantities and delivery times of merchandise ordered from a terminal into a received order master file, transcribes what is input in the master file onto a slip, and enters the slip into a received order file after adding to the slip the address, name and user code number of the user who placed the order. The mail service unit transmits slips held in the ordering service unit to the terminal of a merchandise delivery center via the communication control unit.

A method and apparatus for performing image communication between a plurality of terminals are suggested, in which a composing unit is provided for composing a signal transmitted from a predetermined number of terminals at the transmitting side, together with destination information, into one image signal. An encoding unit encodes the composite signal composed by the composing unit. The composite signal encoded at the encoding unit is transmitted to the receiving side through an exchange at the transmitting side.

An ignition timing control device for an internal combustion engine is provided with a microcomputer which determines the ignition timing (i.e., the angles BTDC) on the basis of a measurement of the period between successive pulses of a crankshaft angle signal in each ignition cycle. The device comprises, in addition to other conventional components, an rpm level judgement device, for determining whether the rpm of the engine is above a predetermined level or not. At the start of each ignition control cycle, this determination of the rpm level is effected on the basis of the measurement of the period of the crankshaft angle signal performed in the immediately preceding ignition cycle. When the rpm is judged to be above the predetermined level, the ignition timing signal is generated in accordance with the value of the ignition timing which has been determined in the preceding ignition cycle; when, on the other hand, the rpm is judged to be not above the predetermined level, the ignition timing signal is generated in accordance with the value of the ignition timing which is determined in the current ignition cycle.

A device for adjusting the height an armrest of a chair including a support disposed on a chair and a receiving/supporting cylinder movably engaged with a support. Extending longitudinally in a slit in the receiving/supporting cylinder is a stepped member. An engaging piece within the cylinder is adapted to be moved into and out of engagement with the stepped member. The engaging piece extends through a slit in the cylinder. Surrounding the receiving/supporting cylinder is an operating cylinder which has circumferentially spaced internal ridges. As the operating cylinder is rotated. the ridges engage the engaging piece and move it into and out of contact with the stepped member.A spiral circumferential groove is also provided in the receiving/supporting cylinder and a pin on the operating cylinder is engaged in the spiral groove whereby rotatable movement of the operating cylinder causes axial movement of the same. Tapered edges are provided on the operating cylinder and a member connected to the receiving/supporting cylinder so that as the operating cylinder is raised and lowered, the member is clamped and unclamped to the support.

A multiple video server system for transmitting data to a second network of a constant bit rate (CBR) through a first network of a variable bit rate (VBR). The server system has a server unit for transmitting data to the first network at a transmission interval (T) adapted to the constant bit rate of the second network. In the case where the constant bit rate of the second network is set to (n) [Mbps] and a transmission data amount which is transmitted at a time to the first network is set to DL, the server unit obtains the transmission interval (T) from T=DL/n and sets.

A card type input/output interface device includes a first connection part for transferring data between a main body of an electronic device and the card type input/output interface device, a second connection part which is coupled to the first connection part and transfers data between an external device and the card type input/output interface device, and a card supporting the first and second connection part. The first connection part is accommodated in the main body when the card type input/output interface device is inserted into a slot provided in the main body.

A demultiplexer receives an MPEG1 system stream obtained by multiplexing encoded data of video and audio and separates the stream into elementary streams (ES) of video and audio. A packetizer forms packetized elementary streams (PES) of MPEG2. Finally, a multiplexer divides the stream into transport packets each having a prefixed length of 188 bytes and, after that, converts the stream to an MPEG2 transport stream (TS).
摘要:
A video information server system which makes it possible for a party to remotely control any of a plurality of video information server apparatuses holding a plurality of types of video information different in type from each other through a communication network and thereby easily obtained desired video information, the system being provided with a video information server center including a plurality of video information server apparatuses and a center control equipment for selecting one of these apparatuses in accordance with a request from a request terminal and sending the video information of the request and the central control equipment being provided with a common management file for recording various data for converting requests from terminals compatible with all of the plurality of video information server apparatuses into requests corresponding to the individual apparatuses.
