Abstract: 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.

Abstract: A communication service unit 2 exchanges messages related to establishment or reestablishment of a logical channel for video with a reception terminal 3, when transmission of a video coded signal to the reception terminal 3 is started or when a transmission source terminal is changed. The communication service unit 2 adds a video coding parameter stored in memory and used in a new transmission source terminal to a message for establishing or re-establishing the logical channel for video and transmits transmitting the resultant message to the reception terminal 3. The reception terminal 3 decodes the video coded signal based on the video coding parameter included in the message thus received.

Abstract: A communication terminal (1) connects, by way of a channel for multimedia communication set via a circuit switched network (4), with a communication service unit (2) so that the communication terminal (1) can send and receive multimedia information. The communication terminal (1) also connects, by way of a control channel set via a packet switched network (5), with an additional service unit 3 so that the communication terminal (1) can send and receive service control information associated with the multimedia information provided by the communication service unit (2). The additional service unit (3) receives the service control information transmitted from the communication terminal (1) by way of the packet switched network (5), transmits a service control signal to the communication service unit (2), and transmits another service control signal, such as the one specifying an operation mode or the one indicating service guidance information, to the communication terminal (1).

Abstract: 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.

Abstract: A program recording/reproducing system demultiplexes predetermined program signals from multiplexed signals into which a plurality of program signals are time-division-multiplexed per predetermined multiplexing unit, and records these demultiplexed program signals. The predetermined program signals are extracted from the multiplexed signals, and the program signals are recorded. The program signals are read out of a recording medium, and the readout program signals are outputted so that an output interval on each multiplexing unit becomes coincident with a time interval in the multiplexed signals. A null packet is inserted in between the two readout program packets in the same state as when recorded, thereby troubleshooting a buffer overflow or underflow occurred during the reproducing process.

Abstract: A method of coloring a water-absorbable plastic partially or totally in a single color or multiple colors in such a manner that no migration or separation of the coloring agents used can take place. A copolymer of a coupler monomer and a water-absorbable plastic monomer, a polymer of a coupler polymer and a water-absorbable plastic monomer or a polymer of a coupler monomer and a water-absorbable plastic polymer is formed into an intermediate product shaped in the form of any desired final product. The intermediate product is immersed in an aqueous solution of a developer consisting of a diazonium double salt and allowed to swell, whereby the diazo-component of the developer penetrates into the plastic. The swollen product is then immersed in an aqueous acid or alkaline solution having an optimum pH value for coupling reaction to allow formation of an azoic dye on the plastic as a result of the coupling reaction.
