Abstract: Methods and apparatuses are provided for setting a block in an electronic device. Content is displayed on a display of the electronic device. The electronic device senses a first touch input on an area for setting the displayed content in the display as a block. The electronic device senses a second touch input while the first touch input is maintained on the area. The electronic device sets at least a part of the content as the block, based on a movement of the second touch input.

Abstract: Encoding and decoding methods are provided. An information object is encoded according to a preset encoding scheme. A preset set of bits is selected from the encoded information object and the selected set of bits is output as a sample. A control packet including information on a sample number is generated. The sample is assembled with the control packet. The sample is modulated into a sound signal according to a preset scheme. An input sound signal is demodulated according to the preset scheme. Sample bits and control packet bits containing information of the sample are separated from each other in demodulated received bits. Address information corresponding to each bit of the sample is generated according to the control packet. A soft decision of the sample bits is summed for each piece of the generated address information. A sample decoding of the summed soft decision of the sample bits is performed.

Abstract: Systems, apparatuses, and methods for securing wireless communication using an acoustic signal are described. In one method involving a first and second device, the second device generates, when connecting to the first device, connection initiation information including key information for secure communication, converts the connection initiation information to an acoustic signal, and transmits the acoustic signal to the first device through an acoustic communication channel. Then the second device monitors a radio wireless channel, which is secured using the key information for secure communication, to determine whether a valid response is received from the first device and, upon receipt of the valid response, discontinues transmission of the acoustic signal and begins communicating with the first device securely on the radio wireless channel.
