Abstract

An exemplary interactive wireless display system includes a remote sub-system, and a local sub-system. The remote sub-system includes an encoder, a wireless transmitter, and a user interface. The local sub-system includes a wireless receiver, a decoder, a display controller, and a display device. The encoder is configured to encode an input displayable signal. The wireless transmitter is configured to transmit the encoded displayable signal. The wireless receiver is configured to receive the encoded displayable signal. The decoder is configured to decode the encoded displayable signal. The display controller is configured to control the display device to display the decoded displayable signal. The user interface is wirelessly interconnected with the display controller and configured to wirelessly interface with the display device.

Claims

1. An interactive wireless display system comprising:

a remote sub-system comprising;

an encoder configured to encode an input displayable signal; and

a wireless transmitter configured to transmit the encoded displayable signal;

a local sub-system comprising;

a wireless receiver configured to receive the encoded displayable signal;

a decoder configured to decode the encoded displayable signal;

a display device; and

a display controller configured to control the display device to display the decoded displayable signal;

wherein the remote sub-system further comprises a user interface wirelessly interconnected with the display controller via a link between the wireless transmitter and the wireless receiver, the user interface being configured to wirelessly interface with the display device.

2. The interactive wireless display system as claimed in claim 1, wherein the remote sub-system is connected to a displayable signal source selected from a group of:

media player, television and computer.

3. The interactive wireless display system as claimed in claim 1, wherein the displayable signal is selected from a group of:

audio/video signal, television output signal, and computer output signal.

4. The interactive wireless display system as claimed in claim 1, wherein the encoder is configured for converting the input displayable signal of various formats into a default format.

5. The interactive wireless display system as claimed in claim 4, wherein the default format is selected from a group of:
