An entering and leaving management system is provided. The management system includes a management terminal including: an authentication history information acquisition section configured to acquire authentication history information; a registered person image acquisition section configured to acquire a registered person image recorded associated with personal identification data of the authentication history information; an image acquisition section configured to acquire an image of a person to be authenticated, recorded associated with an authentication time of the authentication history information; and a listing section configured to list the registered person images and the image of the person to be authenticated on the operation screen side by side with the authentication history information.

Entering and leaving management system

The present invention introduces an apparatus and method for securing a constant bit rate in transmitting various types of media data through multiplexing over an ATM network so as to achieve a constant bit rate communication. Received video/audio information from an information source is encoded at an information source encoder and outputted to a media multiplexer as encoded video/audio information. The media multiplexer multiplexes encoded the video/audio information to obtain fixed-length data as transmission data. The media multiplexer, upon reception of a transmission enable signal from a line interface unit, transmits the transmission data to the line interface unit. The line interface unit assembles the transmission data on an ATM cell format basis and transmits cell data,over the ATM network.

Rate control communication apparatus and method

The object of this invention is to realize the correct and prompt synchronization of data in decoding and reproducing multiplexed coded data multiplexed with a plurality of media coded data in the unit of packet without regard to the configuration or characteristics of the apparatus. To achieve a data decoder that can synchronize the video and audio data correctly, the timing controller obtains a buffering time indicated by the time difference between the decoding end time and the specified presentation time contained in the data, and data buffering is performed by buffer memory. The video decoding end time is latched from the system time counter according to a timing pulse generated by the video decoder when the first decoded data is output from video decoder after the data decoder is activated.
