Method for the transmission of image data
First Claim
1. Method for the transmission and reproduction of image data, in which said image data are transmitted from a sending device to at least one communication terminal and reproduced by image reproducing means, the current viewing direction of the communication terminal'"'"'s user being determined:
- wherein first image data are transmitted with a low resolution over a first transmission channel, wherein said current viewing direction is sent over a reverse channel to said sending device, wherein second image data corresponding to the image areas viewed currently or in future by said at least one user are transmitted with a higher resolution over a second transmission channel, and wherein said first and second image data are superimposed and simultaneously reproduced in said communication terminal.

Abstract
Method for the transmission and reproduction of image data in which said image data are transmitted to a communication terminal and reproduced by image reproducing means, the current viewing direction of the communication terminal'"'"'s user being determined.
First image data are transmitted with a low resolution over a first transmission channel, for example a DVB, whilst second image data corresponding to the image areas viewed currently or in future by the user are transmitted with a higher resolution over a second transmission channel. The first and second image data are superimposed and simultaneously reproduced in the communication terminal.

21. Communication terminal that can receive image data and reproduce them with image reproducing means and that can determine the current viewing direction of the communication terminal'"'"'s user, wherein
it can receive first image data with a low resolution over a first transmission channel, it can receive second image data corresponding to the image areas viewed currently or in future by the user with a higher resolution over a second transmission channel, it can send said viewing direction over a reverse channel, and it can superimpose and simultaneously reproduce said first and second image data.

39. Sending device, wherein it includes the following components:
-
a receiver for receiving data comprising the viewing direction of at least one user transmitted over a reverse channel, a first encoding module for compressing first image data with a low resolution and sending them over a first transmission channel in broadcast mode, a second encoding module for compressing second image data, corresponding to image areas viewed currently or in future by said at least one user, with a high resolution and sending them over a second transmission channel. - View Dependent Claims (53)
