Abstract

A first communication terminal includes a first communication device, a first touch panel for displaying motion picture contents, and a first processor for accepting input of a hand-drawing image. The first processor transmits a hand-drawing image input during display of the motion picture contents and start information for identifying a point of time when input of the hand-drawing image at the motion picture contents is started to a second communication terminal. The second communication terminal includes a second touch panel for displaying motion picture contents, a second communication device for receiving the hand-drawing image and start information from the first communication terminal, and a second processor for displaying the hand-drawing image from the point of time when input of the hand-drawing image at the motion picture contents is started on the second touch panel, based on the start information.

Claims

1. A network system comprising first and second communication terminals,

said first communication terminal including:

a first communication device for communicating with said second communication terminal;

a first touch panel for displaying motion picture contents; and

a first processor for accepting input of a hand-drawing image via said first touch panel,

said first processor transmitting said hand-drawing image input during display of said motion picture contents and start information for identifying a point of time when input of said hand-drawing image at the motion picture contents is started to said second communication terminal via said first communication device,

said second communication terminal including;

a second touch panel for displaying said motion picture contents;

a second communication device for receiving said hand-drawing image and said start information from said first communication terminal; and

a second processor for displaying said hand-drawing image from said point of time when input of said hand-drawing image at said motion picture contents is started on said second touch panel, based on said start information.

2. The network system according to claim 1, further comprising a contents server for distributing said motion picture contents, wherein

said first processor is configured to

obtain said motion picture contents from said contents server according to a download instruction, and

transmit motion picture information for identifying said motion picture contents obtained to said second communication terminal via said first communication device, and

said second processor is configured to obtain said motion picture contents from said contents server based on said motion picture information.

3. The network system according to claim 1, wherein said first processor transmits, via said first communication device, an instruction to eliminate said hand-drawing image to said second communication terminal when a scene of said motion picture contents has changed and/or when an instruction to clear said input hand-drawing image is accepted.

4. The network system according to claim 1, wherein said second processor

calculates a time starting from said point of time when input is started up to the point of time when a scene in said motion picture contents is changed, and

determines a drawing speed of said hand-drawing image on said second touch panel based on said time.

5. The network system according to claim 1, wherein said second processor

calculates a length of a scene in said motion picture contents including said point of time when input is started, and

determines a drawing speed of said hand-drawing image on said second touch panel based on said length.

6. A communication method at a network system including first and second communication terminals capable of communication with each other, comprising the steps of:

displaying, by said first communication terminal, motion picture contents;

accepting, by said first communication terminal, input of a hand-drawing image;

transmitting, by said first communication terminal, to said second communication terminal said hand-drawing image input during display of said motion picture contents and start information for identifying a point of time when input of said hand-drawing image at said motion picture contents is started;

displaying, by said second communication terminal, said motion picture contents;

receiving, by said second communication terminal, said hand-drawing image and said start information from said first communication terminal; and

displaying, by said second communication terminal, said hand-drawing image from said point of time when input of said hand-drawing image at said motion picture contents is started, based on said start information.

7. A communication terminal capable of communicating with an other communication terminal, comprising:

a communication device for communicating with said other communication terminal;

a touch panel for displaying motion picture contents;

a processor for accepting input of a first hand-drawing image via said touch panel, said processor configured to

transmit said first hand-drawing image input during display of said motion picture contents, and first start information for identifying a point of time when input of said first hand-drawing image at said motion picture contents is started to said other communication terminal via said communication device,

receive a second hand-drawing image and second start information from said other communication terminal, and

cause display of said second hand-drawing image from the point of time when input of said second hand-drawing image at said motion picture contents is started on said touch panel, based on said second start information.

8. A communication method at a communication terminal including a communication device, a touch panel, and a processor, comprising the steps of:

causing, by said processor, display of motion picture contents at said touch panel;

accepting, by said processor, input of a first hand-drawing image via said touch panel;

transmitting, by said processor, said first hand-drawing image input during display of the motion picture contents and start information for identifying a point of time when input of said first hand-drawing image at said motion picture contents is started to an other communication terminal via said communication device;

receiving, by said processor, a second hand-drawing image and second start information from said other communication terminal via said communication device; and

causing, by said processor, display of said second hand-drawing image from said point of time when input of said second hand-drawing image at said motion picture contents is started on said touch panel, based on said second start information.
