METHOD OF OPERATING AN INTERACTIVE IMAGE DISPLAY SYSTEM AND IMAGE SOURCE DEVICE FOR IMPLEMENTING THE METHOD |
摘要 |
<p>A method and device make it possible to show information interactively on a user terminal of an image display system, without requiring additional bandwidth for transmitting feedback information. The image display system includes an image source device and a user terminal connected to each other via a link. An input image signal and user command are received and, based on these, a further image signal representing an image part is generated. A compressed image signal is formed from the input image signal and an imposed image part. The compressed image signal is transmitted to the user terminal via the link where decompression occurs.</p> |
