    摘要： A video telephone system which includes a master video telephone terminal (secretary terminal) connected to a communication network and slave video telephone terminals (executive terminals) connected to the master video telephone terminal in which the master video telephone terminal can transfer a call to the slave video telephone terminals. When a call comes into the secretary terminal from a remote terminal on the communication network, a line control section of the secretary terminal sets up a line. Video data and speech data received on the line are decoded by a video signal coding-decoding section and an aural signal coding-decoding section and the decoded signals are output through a display and a speech output device. Sound and images picked up by a microphone and a camera respectively are coded for transmission. Then, if a predetermined instruction of call transfer to an executive terminal is entered on an electronic tablet of the secretary terminal, a communication branch control section of the secretary terminal calls the executive terminal, sets up a line between the secretary and executive terminals on a local transmission network, and connects the line between the secretary terminal and the remote terminal.

    摘要： After a row address and a column address are supplied to a dynamic RAM in response to a row address strobe signal and a column address strobe signal, respectively, a high impedance state is maintained for column address access time period after the fall timing of the column address strobe signal, thereafter data is outputted to a data bus, and the high impedance state of the data bus is quickly resumed after the rise timing of the column address strobe signal. If different column addresses of RAM at the same row address are successively read, data are read and outputted to the data bus in response to a change only in the column address strobe signal, and thereafter, even after the high impedance state of the data bus is quickly resumed, a data value is held by the data bus until the dynamic RAM outputs the data.

    摘要： Method and device can be provided which can establish two or more communication channels for a called terminal having different called addresses for different channels by a single calling address. When keys are input in the order of "0014723244*3245#" for example from a key input section, a key input control section transfers the key input contents before "*" to a communication control section as dial information and starts a send operation with the dial information "0014723244" as a called party address. Subsequently, the key input control section replaces the lower order digits of the key input contents before * by the contents between "*" and "#". It transfers the key input contents after replacement to the communication control section as dial information and starts the send operation with the dial information "0014723245" as the called party address.

    摘要： A demultiplexing and decoding apparatus for coded audio and video data realized with a simple circuit construction and reduced processing load, which processes a packet with higher priority over other packets, prior to the other packets. A plurality of TS packet buffers 73 and 74, for storing input TS packets until they are interpreted, are set in a RAM 7, and processing priority orders are respectively set in the buffers. A PID filter 31 demultiplexes a TS packet, with a PID designated in PID table 36, from a supplied transport stream. A TS packet with higher priority is stored into the TS packet buffer 73, while a TS packet with lower priority is stored into the TS packet buffer 74. Regardless of the input order, the TS packet stored in the TS packet buffer 73 is processed by the CPU 6 prior to the TS packet stored in the TS packet buffer 74.
