Abstract

The present invention provides systems and methods for using a recipient handset as a remote screen for the initiator handset, while the two handsets are engaged in a voice call. The systems and methods allow a party to transmit its screen buffer to the other party during a voice call between the parties, without allowing the receiving party to store it or forward it to a third party.

Claims

1. A method for utilizing a recipient handset as a remote screen for an initiator handset during a voice call between the initiator handset and the recipient handset carried over a circuit-switched (CS) network, wherein both handsets are on a wireless network utilizing multiple Radio Access Bearer (mRAB) technology, the method comprising:

a personal agent (PA) on an initiator handset negotiating display capabilities with a PA on a recipient handset via a serving node (SN) residing on a packet-switched (PS) network;

the PA on the initiator handset capturing the initiator handset'"'"'s screen buffer and transmitting it to the SN;

the SN forwarding the screen buffer to a PA on the recipient handset;

the PA on the recipient handset receiving the screen buffer from the SN and storing it in the screen buffer of the recipient handset; and

the recipient handset rendering the received screen buffer, wherein the recipient handset is unable to store or make a copy of the screen buffer.

2. The method of claim 1, further comprising the SN converting the received screen buffer to a format capable of being rendered by the recipient handset prior to forwarding the screen buffer to the PA on the recipient handset.

3. The method of claim 1, wherein rendering of the received screen buffer is initiated on the recipient handset before the entire screen buffer has been received.

4. The method of claim 1, wherein the rendering of the screen buffer on the initiator handset and on the recipient handset is coordinated.

5. The method of claim 1, wherein the PA on the recipient handset captures the screen buffer and sends it to the SN at a predetermined rate.

6. The method of claim 1, wherein the initiator handset'"'"'s screen buffer contains a representation of a media object residing on the initiator handset.

7. The method of claim 6, wherein the media object is a video clip, a digital image, a SMS, a MMS, an IM message or an E-mail message.

8. The method of claim 7, wherein the media object has an audio component, which is transmitted to the recipient handset over the CS network.

9. The method of claim 7, wherein the media object has an audio component, which is transmitted to the recipient handset over the PS network.

10. The method of claim 6, further comprising a media player (MP), residing on the initiator handset, sending a representation of the media object to a renderer logic residing on the initiator handset.

11. The method of claim 10, further comprising the renderer logic generating the screen buffer.
