Abstract
In an communication system comprising a transmitter unit for digitally converting an input image signal and for outputting the converted image signal, and a receiver unit for entering thereinto the image signal derived from the transmitter unit and for displaying this entered image signal, the receiver unit outputs to the transmitter unit, an end signal for indicating that a display process of the image signal entered from the transmitter unit is accomplished.
Claims12
An image communicating system comprising:
- a transmitter unit for digitally converting an input image signal and for outputting the converted image signal through a network;
- and
- a receiver unit for saving in a memory the image signal derived from the transmitter unit through the network and for displaying the image signal saved in the memory on a display;
- wherein said receiver unit transmits an end signal indicating that a display process has been completed to the transmitter unit through the network if the image signal saved in the memory is normally displayed on the display, and the display process for displaying the image signal on the display is completed.
A method for communicating images comprising:
- a transmitter unit for digitally converting an input image signal and for outputting the converted image signal through a network;
- and
- a receiver unit for saving in a memory the image signal derived from the transmitter unit through the network and for displaying the image signal saved in the memory on a display;
- wherein said receiver unit transmits an end signal indicating that a display process has been completed to the transmitter unit through the network if the image signal saved in the memory is normally displayed on the display, and the display process for displaying the image signal on the display is completed.
An apparatus for transferring images in an image communication system the apparatus comprising at least a receiver capable of being coupled to a transmitter through the image communication system, the apparatus configured to;
- digitally convert an input image signal;
- enter a derived image signal derived from the converted input image signal;
- display the derived image signal at the receiver;
- output, an end signal from the receiver, the end signal indicating that the derived image signal has been displayed;
- a receiver for saving in a memory through a network an image signal from a transmitter unit that digitally converts an input image signal and transmits the converted image signal and its reproduction control information through a network, and for displaying the image signal saved in the memory on a display;
- and
- wherein said receiver unit transmits an end signal indicating that a display process has been completed to the transmitter unit through the network if the image signal saved in the memory is normally displayed on the display, and the display process for displaying the image signal on the display completed.
An apparatus for transferring images in an image communication system the apparatus comprising at least a transmitter capable of being coupled to a receiver through the image communication system, the apparatus configured to;
- digitally convert an input image signal;
- enter a derived image signal derived from the converted input image signal;
- receive at the transmitter an end signal, the end signal indicating that the derived image signal has been displayed;
- a transmitter for digitally converting an input image signal and transmits the converted image signal through a network, and for displaying the image signal saved in a memory of a receiver unit on the display;
- wherein said receiver unit receives though the network an end signal indicating that a display process has been completed which is transmitted from the receiver unit if the image signal saved in the memory by the receiver units is normally displayed on the display, and the display process for displaying the image signal on the display is completed.
