Appeal No. 1997-2656
Application No. 07/907,472
BACKGROUND
The appellants’ invention relates to a data communication apparatus having a
common memory for storing video and audio data. The common memory stores data
for each type of data starting at the high and low addresses and increasing or
decreasing toward the other address to leave a block in the middle. Therefore,
additional flexibility is gained in setting a boundary address between the two data areas.
Additionally, the display or the remaining space in memory is made in a user- friendly
terms of pages and messages for facsimile transmission and for answering machine
operation. An understanding of the invention can be derived from a reading of
exemplary claim 1, which is reproduced below.
1. In a data communication apparatus including communication means for
transmitting and receiving video data and audio data, said video data being
derived from documents, a memory for storing at least video data and audio data
received by said communication means, memory control means for executing
management of utilization of said memory and for controlling data write and read
operations of said memory, and data display means;
the improvement comprising display control means for controlling said
data display means to display first memory capacity information representing an
amount of capacity available in said memory for storing video data and second
memory capacity information representing an amount of capacity available in
said memory for storing audio data, said display control means comprising
means for expressing said first memory capacity information as a number of first
data units, each of said first data units consisting of an amount of data
corresponding to one standard document page, and for expressing said second
memory capacity information as a number of second data units, each of said
second data units consisting of an amount of data corresponding to one
fixed-duration telephone message, and means for controlling said display means
to display said number of first data units and number of second data units.
