Abstract

A transmission and reception system, in which during transmission a background picture and objects #1 to #3 are transmitted at a transmission rate of R/4 each. On the reception side, a picture composed of the objects #1 to #3 and the background picture is displayed with a particular spatial resolution and a particular temporal resolution. When the object #1 is dragged at a particular time t1, on the transmission side, the transmission of the background picture and the objects #2 and #3 is stopped. Only the object #1is transmitted at the transmission rate of R of the transmission path. Thus, a picture of which the spatial resolution of the object #1 dragged is improved at the sacrifice of the temporal resolution of the picture.

Claims

1. A transmitting system for transmitting image data comprising:

a receiving unit configured to receive control information transmitted from a receiving apparatus;

a categorizing unit configured to categorize the image data corresponding to the control information, thereby providing a categorized result of the image data; and

a transmitting unit configured to transmit the image data to the receiving apparatus corresponding to the categorized result of the image data,

wherein the receiving apparatus displays the image data transmitted from the transmitting unit,

wherein the control information contains a user focused point of the image data displayed by the receiving apparatus, and

wherein the categorizing unit categorizes the image data corresponding to a specified region that contains the user focused point of the image data.

2. A transmitting method for transmitting image data comprising the steps of:

receiving control information;

categorizing the image data corresponding to the control information;

generating a categorized result of the image data;

transmitting the image data corresponding to the categorized result of the image data;

displaying at a receiving apparatus the image data transmitted;

identifying a user focused point of the image data displayed by the receiving apparatus; and

categorizing the image data corresponding to a specified region that contains the identified user focused point of the image data.

3. A computer-readable medium for storing a program that when executed causes a computer to perform a transmitting process comprising the steps of:

receiving control information;

categorizing the image data corresponding to the control information;

generating a categorized result of the image data;

transmitting the image data corresponding to the categorized result of the image data;

displaying at a receiving apparatus the image data transmitted;

identifying a user focused point of the image data displayed by the receiving apparatus; and

categorizing the image data corresponding to a specified region that contains the identified user focused point of the image data.
