Abstract: Provided is a network system including at least first and second communication terminals capable of communicating with each other via a network. The first communication terminal causes handwritten data input in response to an instruction for a point on an image to be displayed in a certain position on the image corresponding to this point, associates the point information about the point with the handwritten data and transmits the point information and the handwritten data to the second communication terminal. Based on the point information and the handwritten data from the first communication terminal, the second communication terminal causes at least a part of the image to be displayed on a second display and also causes the handwritten data to be displayed in a location in accordance with the point information.

Abstract: A communication terminal includes a touch panel, a communication device for communicating with an other communication terminal, and a processor for reproducing contents using a touch panel, temporarily stopping reproduction of the contents and transmitting a stop instruction to the other communication terminal according to a first input, resuming the reproduction of the contents and transmitting the resumption instruction to the other communication terminal according to a second input, temporarily stopping the reproduction of the contents according to a stop instruction from the other communication terminal, and resuming the reproduction of the contents according to a resumption instruction from the other communication terminal.

Abstract: A first terminal (100A) receives a handwriting instruction and a pen type, and transmits the handwriting instruction and the pen type to a server (400). The server (400) refers to a memory to convert the handwriting instruction from the first terminal (100A) into drawing data used for displaying a handwriting image corresponding to the pen type from the first terminal (100A), and transmit the drawing data to the first terminal (100A). The first terminal (100A) displays the handwriting image corresponding to the pen type based on the drawing data from the server (400).

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.

Abstract: A communication terminal includes a first communication device, a second communication device, a speaker, a microphone, and a processor. The processor performs audio communication with another communication terminal via the first communication device, the speaker and the microphone and during the audio communication with the other communication terminal the processor receives an instruction issued to start data communication and while performing the audio communication the processor also performs the data communication in response to the instruction with the other communication terminal via the second communication device.
