Abstract

An interactive display system, an operation method thereof, and an image intermediary apparatus are provided. The image intermediary apparatus is adapted to at least divide a display area of an interactive display apparatus into a first frame region and identify external electronic apparatuses to establish a correspondence relation between the external electronic apparatuses and image signals of the external electronic apparatuses, and display a first image based on a first image signal among the image signals of the external electronic apparatuses on the first frame region. When interactive position information indicates that an interactive event occurs on the first frame region, the image intermediary apparatus acquires a communication identification information corresponding to the first image signal according to the correspondence relation, and transmits a coordinate corresponding to the interactive position information to an external electronic apparatus corresponding to the communication identification information among the external electronic apparatuses.

First claim

What is claimed is:

1 . An interactive display system, configured to receive different image signals from a plurality of external electronic apparatuses and display corresponding images, comprising:
an interactive display apparatus, comprising a display area and configured to sense an interactive event within the display area in order to acquire interactive position information; and an image intermediary apparatus, coupled to the interactive display apparatus via a first wireless channel in order to receive the interactive position information, wherein the image intermediary apparatus is adapted to at least divide the display area into a first frame region and identify the external electronic apparatuses in order to establish a correspondence relation between the external electronic apparatuses and the image signals of the external electronic apparatuses, and display a first image based on a first image signal among the image signals of the external electronic apparatuses on the first frame region of the interactive display apparatus, and wherein the image intermediary apparatus is adapted to acquire first communication identification information corresponding to the first image signal according to the correspondence relation and transmit a coordinate corresponding to the interactive position information to a first external electronic apparatus corresponding to the first communication identification information among the external electronic apparatuses when the interactive position information indicates that the interactive event occurs on the first frame region.

2 . The interactive display system of claim 1 , wherein the interactive display apparatus further comprises an interactive projection screen and a projector, wherein
the interactive projection screen has the display area, and the projector is configured to project the first image based on the first image signal among the image signals of the external electronic apparatuses on the first frame region of the display area of the interactive projection screen; wherein the interactive display apparatus is configured to sense the interactive event within the display area and acquire the interactive position information.

3 . The interactive display system of claim 1 , wherein the first external electronic apparatus is adapted to transmit the first image signal to the image intermediary apparatus via a first image transmission channel, and the image intermediary apparatus is adapted to transmit the coordinate to the first external electronic apparatus by using the first communication identification information via a second wireless channel different from the first image transmission channel.

4 . The interactive display system of claim 3 , wherein the image intermediary apparatus is adapted to transmit first image identification data to the first external electronic apparatus via the first image transmission channel and receive a plurality of packets transmitted back from the first external electronic apparatus via the second wireless channel, wherein at least one of the packets contains the first communication identification information of the first external electronic apparatus and the first image identification data received by the first external electronic apparatus, and the image intermediary apparatus is adapted to record the first communication identification information and the first image identification data into the correspondence relation.

5 . The interactive display system of claim 3 , wherein the image intermediary apparatus is configured to divide the display area into the first frame region and a second frame region and display the first image based on the first image signal and a second image based on a second image signal among the image signals of the external electronic apparatuses on the first frame region and the second frame region of the interactive display apparatus, respectively, and the image intermediary apparatus is adapted to acquire second communication identification information corresponding to the second image signal according to the correspondence relation and transmit the coordinate corresponding to the interactive position information to a second external electronic apparatus corresponding to the second communication identification information among the external electronic apparatuses when the interactive position information indicates that the interactive event occurs on the second frame region.

6 . The interactive display system of claim 5 , wherein the second external electronic apparatus is adapted to transmit the second image signal to the image intermediary apparatus via a second image transmission channel, and the image intermediary apparatus is adapted to transmit the coordinate to the second external electronic apparatus by using the second communication identification information via the second wireless channel.

7 . The interactive display system of claim 6 , wherein the image intermediary apparatus is adapted to transmit second image identification data to the second external electronic apparatus via the second image transmission channel and receive a plurality of packets transmitted back from the second external electronic apparatus via the second wireless channel, wherein at least one of the packets contains the second communication identification information of the second external electronic apparatus and the second image identification data received by the second external electronic apparatus, and the image intermediary apparatus is adapted to record the second communication identification information and the second image identification data into the correspondence relation.

8 . The interactive display system of claim 6 , wherein the first image transmission channel comprises a first image transmission cable, the second image transmission channel comprises a second image transmission cable, the first wireless channel comprises a first wireless local area network, and the second wireless channel comprises a second wireless local area network.

9 . The interactive display system of claim 7 , wherein the first image identification data comprises a machine name field and a resolution field, the second image identification data comprises another machine name field and another resolution field, the machine name fields record machine names of the external electronic apparatuses, and the resolution fields record resolution information of the external electronic apparatuses.

10 . The interactive display system of claim 9 , wherein the image intermediary apparatus is adapted to convert the coordinate according to the resolution information and transmit the converted coordinate to the first external electronic apparatus or the second external electronic apparatus based on the interactive position information.

11 . An operation method of an interactive display system, the interactive display system comprising an interactive display apparatus and an image intermediary apparatus, and the operation method comprising:
receiving different image signals from a plurality of external electronic apparatuses and identifying the external electronic apparatuses by the image intermediary apparatus in order to establish a correspondence relation between the external electronic apparatuses and the image signals of the external electronic apparatuses; at least dividing a display area of the interactive display apparatus into a first frame region by the image intermediary apparatus; displaying a first image based on a first image signal among the image signals of the external electronic apparatuses on the first frame region by the image intermediary apparatus; sensing an interactive event within the display area by the
