Abstract

A method for transferring scribble data along with voice includes connecting at least two electronic devices through a GSM network, accumulating and down sampling the scribble coordinates, which are converted to a speech-like signal that is sent along with voice data packets simultaneously in the GSM network.

Claims

1. A system for exchanging scribble data information between electronic devices, the system comprising:

a transmitting electronic device for capturing scribble data, converting the scribble data to a speech-like signal, interleaving the speech-like signal with a speech signal, and transmitting the interleaved signal to a receiving electronic device, the transmitting electronic device having an interface for scribbling an input; and

the receiving electronic device for receiving the interleaved signal, extracting a speech-like signal from the interleaved signal, decoding the extracted speech-like signal to generate scribble data packets, and displaying the scribble data packet,

wherein the scribble data is sent simultaneously with the speech signal in real time.

2. The system as claimed in claim 1, wherein the transmitting and receiving electronic devices refer to mobile phones or electronic devices performing GSM (Global System for Mobile) communications.

3. The system as claimed in claim 1, wherein the transmitting electronic device inserts identification bits to the speech-like signal for interleaving with an actual speech signal.

4. The system as claimed in claim 1, wherein the scribble data is received simultaneously with voice in a receiving mobile phone or the receiving electronic device.

5. A method of transmitting scribble data between transmitting and receiving electronic devices, the method comprising:

identifying scribble coordinates of scribble data on the transmitting electronic device;

sampling the scribble coordinates;

synthesizing segments of the scribble data to generate a speech-like signal;

inserting identification bits in the speech-like signal;

interleaving the speech-like signal with an actual speech signal; and

transmitting the interleaved signal to the receiving electronic device through a channel for voice communication.

6. The method as claimed in claim 5, wherein a stream of the scribble data is represented by coordinates x and y, has one of a trapezoidal or a saw tooth waveform, and is synthesized to a speech-like signal.

7. The method as claimed in claim 6, wherein the identification bits are inserted at the beginning of the speech-like signal.

8. A method of receiving scribble data between electronic devices, the method comprising:

receiving a speech signal from a transmitting electronic device;

identifying identification bits from the received speech signal to identify speech-like packets;

separating the identified speech-like packets to extract scribble data;

extracting and interpolating x and y position data for the scribble data; and

displaying the interpolated x and y position data on a display unit of a receiving electronic device.

9. The method as claimed in claim 8, wherein the scribble data is received simultaneously with voice in real time in an electronic device for GSM (Global System for Mobile) communications.

10. An apparatus for transmitting scribble data between electronic devices, the apparatus comprising:

a display unit; and

a controller for receiving scribble data from the display unit, identifying scribble coordinates of the scribble data, sampling the scribble coordinates, synthesizing segments of the scribble data to generate a speech-like signal, inserting identification bits in the speech-like signal, interleaving the speech-like signal with an actual speech signal, and transmitting the interleaved signal through a channel for voice communication.

11. The apparatus as claimed in claim 10, wherein a stream of the scribble data is represented by coordinates x and y, has one of a trapezoidal or a saw tooth waveform, and is generated as a speech-like GSM (Global System for Mobile) signal.

12. The apparatus as claimed in claim 11, wherein the identification bits are inserted at the beginning of the speech-like signal.

13. An apparatus for receiving scribble data between electronic devices, the apparatus comprising:

a display unit; and

a controller for receiving a speech signal from a transmitting electronic device, identifying identification bits from the received speech signal to identify speech-like packets, separating the identified speech-like packets to extract scribble data, extracting and interpolating x and y position data for the scribble data, and displaying the interpolated x and y position data on the display unit.

14. The apparatus as claimed in claim 13, wherein the scribble data is received simultaneously with voice in real time in an electronic device for GSM (Global System for Mobile) communications.
