Abstract
The transmission of digital data from a screen to a receiver is implemented by display of the digital data as a first representation of dither patterns on the screen and reception of that digital data on the receiver as a second representation. For transmission, the receiver, equipped with a photo-detector for reception, is positioned in front of and in the field of view of the screen. Dither patterns enable reception from any kind of screen, either CRT screen, LCD screen, OLED screen, back-lit screen, or plasma screen, regardless of operation as a computer monitor or a TV screen. A first portion of the screen may be reserved as a window for data transmission, while a second portion retains regular display features. The screen and the receiver are either portable or static.
Claims69
A transmission method for transmitting digital data from a transmitter to a receiver, the transmitter comprising a screen and the method comprising the steps of:
- displaying the digital data on the screen as a first representation comprising at least one dither pattern, and
- deriving from the screen a second representation representative of the first representation.
A transmission method for transmitting digital data from a transmitter to a receiver, the transmitter comprising a screen and the method comprising the steps of:
- displaying the digital data on the screen as a succession of at least one pattern defining a first representation,
- deriving from the screen a second representation representative of the first representation, and
- configuring the at least one pattern of the first representation to comprise at least one dither pattern.
A transmitter comprising a processor coupled to a memory storing a processor-readable program and a screen coupled to and driven by the processor for display of digital data originating from a data source, for transmission via the screen of the digital data to a receiver comprising a photo-sensor, and the transmitter comprising:
- a first representation of the digital data configured for display on the screen,
- a second representation of the digital data being derived by the receiver from the screen, the second representation being representative of the first representation, and
- the first representation comprising at least one dither pattern.
A transmitter apparatus comprising a processor coupled to a memory storing a processor-readable program and a screen coupled to and driven by the processor for display of digital data originating from a data source, for transmission via the screen of the digital data to a receiver comprising a photo-sensor, and the transmitter comprising:
- at the transmitter:
- a first representation of the digital data configured for display on the screen as a succession of at least one pattern, and
- at the receiver:
- a second representation being derived from the screen and being representative of the first representation, and
- the first representation being configured to comprise at least one dither pattern.
A system comprising a transmitter with a screen operating in association with a receiver comprising a photo-sensor positioned in front of and in a field of view of the screen, the receiver receiving digital data displayed on the screen, the system comprising:
- a first representation of the digital data being displayed on the screen,
- a second representation of the digital data being derived by the receiver from the screen, the second representation being representative of the first representation, and
- the first representation comprising at least one dither pattern.
A system comprising a transmitter with a screen operating in association with a receiver comprising a photo-sensor positioned in front of and in a field of view of the screen, the receiver receiving digital data displayed on the screen, the system comprising:
- at the transmitter:
- a first representation of the digital data configured for display on the screen as a succession of patterns, and
- at the receiver:
- a second representation being derived from the screen and being representative of the first representation,
- the first representation being configured as a succession of dither patterns.
