Abstract

The invention relates to a system and method for displaying and transmitting a sequence of images to listeners. The method comprises the following steps: transferring a sequence of images displayed to a transmitting device; transmitting by the transmitting device the images displayed in real time over a multicast wireless communication network, preferably WI-FI; receiving and displaying the images transmitted by a receiving device of the listener; optionally processing and/or annotating the images received by the listener on his device. The invention also relates to a system for the implementation of this method.

Claims

1. Method for displaying a sequence of images by a presenter to listeners, comprising:

(a) displaying by a presenter images out of a sequence of images and simultaneously transferring the images displayed by a presenting device to a transmitting device;

(b) processing, storing and transmitting of the images transferred, by the transmitting device through a wireless network;

(c) receiving of the images transmitted by the transmitting device and displaying same on receiving devices of the listeners;

(i) transmitting the sequence of images is by the transmitting device in real time through a wireless multicast network, and upon transmittal of the last image displayed, the sequence of the previously displayed images is re-transmitted; and

(ii) enabling selection of one or more images from the sequence of images transmitted by the listener for storage on the receiving device and for processing and enabling annotation by means of software loaded on the receiving device as an application from the Internet or from the transmitting device.

2. Method according to claim 1, wherein the re-transmittal of the sequence of the previously displayed images continues until the presenter displays a new image.

3. Method according to claim 1, wherein the images are displayed on the receiving device in two formats:

a full screen mode for displaying to the listener the most recent image displayed by the presenter in full mode;

a picture-in-picture mode, for processing or annotation of the most recent image displayed by the listener,

wherein apart from the image most recently displayed, also the sequence of the previously displayed images is displayed in smaller format at the bottom of the screen.

4. Method according to claim 3 wherein following processing or annotation of an image by a listener, the full mode is displayed again.

5. System for displaying a sequence of images by a presenter to listeners, comprising the following means:

(a) a presenting device suitable for displaying images out of a sequence of images by a presenter to listeners and for transferring same to a transmitting device;

(b) a transmitting device suitable for receiving, storing and transmitting the sequence of images displayed and transferred to it;

(c) a receiving device suitable for receiving, storing and displaying the images transmitted on a screen to the listener;

wherein (i) the transmitting device is suitable to transmit the sequence of images transferred from the presenting device in real time by means of a wireless multicast network, wherein upon transmittal of the last image displayed, the sequence of the previously displayed images is re-transmitted; and

wherein (ii) the receiving device comprises software loaded as an application from the internee or from the transmitting device, enabling the listener to select images from the sequence of images transmitted and for storage and annotation of the selected images.

6. System according to claim 5, wherein the sequence of images is transferred by digital means from the presenting device to the transmitting device.

7. System according to claim 6, wherein the transmitting device is suitable to transmit the images transferred on the one hand digitally to a projection device, and on the other hand by means of a multicast wireless transmitting module.

8. System according to claim 5, wherein the transmitting device comprises encryption software for securing the images transmitted to the receiving device.

9. System according to claim 5, comprising authentication software enabling the listener to authenticate prior to receipt of the images displayed.

10. System according to claim 5, wherein the receiving device is suitable for storing by means of an internet-connection the images selected by the listener with annotations in a private storage folder of the listener in the cloud.

11. System according to claim 5, wherein the receiving device is a mobile data-processing apparatus, for example a laptop, a tablet, a smartphone.

12. System according to claim 5, wherein the sequence of images comprises a continuous or discrete stream of still and/or moving images in a presentation format.

13. System according to claim 12, wherein the images are supplemented with audio data.
