Abstract: A communication apparatus is to be connected to a network to establish, one or more connection with one or more processing apparatus connected to the network, to perform at least one of transmission and reception of data. The communication apparatus includes a reception device, a judgment device and a protection device. The reception device receives a disconnection request for disconnection of the connection, from the processing apparatus. The judgment device judges whether the disconnection request as received is legal or not. The protection device causes, only when there was made a judgment that the disconnection request as received is not legal, disablement of execution of a disconnection processing in response to the disconnection request to protect the connection.

Abstract: An information data transmitting and receiving device is provided, which can reduce a load of a host CPU. In this information data transmitting and receiving device, in a case where an identifier of received information data is coincident with a predetermined identifier, the received information data is stored in a first receiving buffer. In a case where those identifiers are different from each other, the received information data is stored in a second receiving buffer.

Abstract: A reception interface unit in a transmission system wherein time series data is divided into data groups and a data packet with reproduction specification time data specifying a time at which each data piece in the data groups should be reproduced, added to the data groups is transmitted on a transmission bus in a time division manner.

Abstract: A transmission interface unit in a transmission system wherein time series data is divided into data groups and a data packet comprising reproduction specification time data specifying the time at which each data piece in the data groups should be reproduced, added to the data groups is transmitted on a transmission bus in a time division manner. The reception interface unit has a cycle timer for counting the reference time of the home machine based on the reference time on the transmission bus, a generation section for generating the reproduction specification time data, an addition section for dividing the time series data into data groups, putting into packets, and adding the reproduction specification time data to the data in the packets, and a rewrite section for rewriting the reproduction specification time data.

Abstract: A transmission managing apparatus included in an information transmitting system comprising a serial bus, an IRM node, which has a resource register for storing a channel used for an information transmission executed in a time division manner on the serial bus and a transmission occupation period occupied for the information transmission, for indicating the channel and the transmission occupation period and a general node for insuring a non-used channel and a preservable period, which is the transmission occupation period, that can be occupied, while referring to a memory content of the transmission state memory, to thereby carry out the information transmission. The transmission managing apparatus is provided with: a comparator for monitoring whether or not the memory content is updated; and a command generator for reporting a fact of the updating through the serial bus to the general node when updated.

Abstract: An information communication apparatus is provided with: a data preparation section which generates communication data having a predetermined data form for transfer to a serial bus based on data such as audio or video data; a communication section including a communication layer; and a control section which controls the data preparation section and communication section, and determines a data transmission speed based on issuance of a transaction and reception of an acknowledge packet.
