Abstract
A data communication apparatus includes a transmitter that is operable in either a memory transmission mode, wherein data converted by a data converter is transmitted to a destination, or in another transmission mode in which data other than the converted data is transmitted to a destination. The apparatus discriminates whether the data converter is available to convert data or not, and operates the transmitter in the memory transmission mode when the data converter is available.
Claims7
A data communication apparatus comprising:
- input means for inputting data;
- memory means for storing data input by said input means as stored data;
- data conversion means for converting said stored data into converted data;
- transmitting means for transmitting data through a plurality of channels,
- said transmitting means being operable in a memory transmission mode wherein said converted data is transmitted to a destination, said transmitting means also being operable in another transmission mode wherein data other than said converted data is transmitted to a destination,
- said transmitting means being operable to transmit data in said memory transmission mode and said other transmission mode in parallel;
- and
- control means for discriminating whether said data conversion means is available to convert said stored data or not, and for operating said transmitting means in said memory transmission mode when said data conversion means is available.

A data communication apparatus comprising:
- input means for inputting data;
- memory means for storing data input by said input means as stored data;
- conversion means for converting the stored data to converted data which is suitable for a desired destination;
- first transmission means for transmitting the data input by said input means to the desired destination without using said memory means and said conversion means;
- second transmission means for transmitting the stored data to the desired destination by using said conversion means;
- and
- control means for causing said first transmission means to transmit the input data in response to a first request for direct transmission, for causing said second transmission means to transmit the stored data using said conversion means in response to a second request for memory transmission, and for limiting operation of said second transmission means in accordance with a usage condition of said conversion means.
