Method of controlling a data transmission and communication apparatus that transmits image data in burst mode using the user datagram protocol
First Claim
1. A method of controlling data transmission for a communication apparatus, comprising the steps of:
- receiving control data from a communicating counterpart indicating a receiving buffer size thereof;
determining data transmission speed based on a relationship between said receiving buffer size indicated in said control data from said communication counterpart and a reference memory size provided to said communication apparatus beforehand; and
transmitting image data to said communicating counterpart at the determined data transmission speed in a burst transmission mode.

Abstract
A method of controlling data transmission for a communication apparatus includes a step in which a communication apparatus is informed of a receiving buffer size of a counterpart of communication, a step of determining data transmission speed at which image data are transmitted as user datagram procedure packets by comparing the receiving buffer size of the communication counterpart and a reference memory size, and a step of transmitting the user datagram packets of the image data in a burst transmission mode. The communication apparatus can determine the data transmission speed so that it can transmit image data in a burst transmission mode with a minimum risk of data loss.

11. A communication apparatus, comprising:
-
a gateway unit that exchanges data with a communicating counterpart through a packet exchange network; and
a control unit that receives control data from said communicating counterpart through said gateway unit, said control data indicating a receiving buffer size thereof, determining a data transmission speed based on a relationship between said receiving buffer size indicated in said control data from said communication counterpart and a reference memory size, and causing said gateway unit to transmit image data to said communicating counterpart at the determined data transmission speed in a burst transmission mode. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
