Problems solved by technology

However, if the viewpoint moves rapidly, such as in the case of wide image formats or sudden pupil movements, the system's reaction time may be so slow that an image region may suddenly appear with poor resolution at the center point of the viewing area
In addition, this method is not suitable for sending image data to multiple users at the same time

Embodiment Construction

[0020] exist figure 1 , reference symbol 1 refers to a sending device which can for example consist of a commercial communication server with hardware and software components for communicating with a number of communication terminals 8 via two different transmission channels 4 , 7 . Reference numeral 10 refers to image data, for example digital data files, the content of which can be displayed to the user 9 by suitable rendering means, for example in the form of still images or preferably animated images. The image data can be, for example, digitized image sequences (such as movies or television programs) or other multimedia data, such as HTML data containing static and / or animation data and / or speech data, for example. In a variant of the invention, the image data 10 are specifically marked with those image regions and image segments which are of particular interest and which are most likely to be viewed by the viewer, as will be described in more detail later.

Abstract

The invention relates to a method for transmitting and reproducing image data according to which said image data are transmitted to a communication terminal and are respresented by image reproducing devices, the current viewing direction (A) of the user of the communication terminal being determined. First image data are transmitted by a first transmission channel, for example via DVB, at low resolution, while second image data that correspond to the image areas that are viewed by the user currently or in the future are transmitted by a second transmission channel at a higher resolution. The first the second image data are superimposed in the telecommunication terminal and are respresented simultaneously.

Description

technical field [0001] The invention relates to a method for transmitting image data and a device suitable therefor. Background technique [0002] For image data, especially digital data, which can be displayed graphically to the user with suitable rendering tools, they are often compressed before transmission in order to reduce the transmission time, and decompressed before or during reproduction. Various standards are known for compressing and decompressing image data, for example the various MPEG standards (Moving Picture Experts Group). [0003] Patent application WO98 / 33315 (University of Texas) has described another image data compression method based on the physiological characteristics of the human eye, wherein the human eye requires maximum resolution (observation area) only in the image area projected to the center of the retina of the eye. The peripheral image regions can be displayed with a lower resolution without significant loss of quality. This patent appli...
