ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an image communication apparatus and an image communication method.
2. Related Background Art
FIG. 10
shows a conceptual view of a prior art computer based multi-point image display system. In the multi-point image display system shown in
FIG. 10
, image communication terminals
1202
,
1203
,
1204
,
1205
and
1206
are connected to a network
1120
to form a multi-point image display system which allows mutual communication of images, voices and data among image communication terminals. In
FIG. 10
, numeral
1201
denotes a communication terminal housing.
The network
1120
is a bus type network such as Ethernet (trademark). In the present example, the image communication terminals
1203
,
1204
,
1205
and
1206
are image transmission terminals.
In the above prior art apparatus, when a plurality of image transmission terminals
1203
-
1206
simultaneously transmit images, collisions (a plurality of communication terminals transmit packets simultaneously and the packets are broken) occur on the network
1120
and image packets may be lost. As a result, the images cannot be successfully reproduced.
SUMMARY OF THE INVENTION
It is an object of the present invention to solve the above problem.
It is another object of the present invention to reduce the collision occurring on the network.
It is other object of the present invention to permit immediate operation for displaying the images after a plurality of image packets have been received.
The present invention is featured by forming the image by an image forming request noticed by request notifying means and notifying the image forming request before an image transmission request.
It is a further object of the present invention to provide an image communication apparatus and an image communication method which have a novel function.
