Publication number: 20140241127Abstract: 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.Type: ApplicationFiled: May 1, 2014Publication date: August 28, 2014Applicant: Samsung Electronics Co., Ltd.Inventors: Hee-Won JUNG, Seung-Gun PARK, Gi-Sang LEE, Jun-Ho KOH, Sang-Mook LEE, Sergey ZHIDKOV

According to one of the described methods, when it is determined that the target has left the recognizable range of the multimedia system, sensor information is acquired from a portable electronic device (or controller) the user has been using to control the multimedia system, and the acquired sensor information is used to determine where the user is, relative to the recognizable range. In one example, the user is asked to make a gesture with the portable electronic device, and the sensor information concerning that gesture is used to determine the user's relative location. In another example, the sensor information recorded at the time the user left the recognizable range is used to determine the user's relative location.Type: ApplicationFiled: September 18, 2013Publication date: March 20, 2014Applicant: Samsung Electronics Co., Ltd.Inventors: Jin-Wuk CHOI, Dong-Wook KWON, Jung-Seop KIM, Kyung-II KIM, Min-Ho KIM, Gi-Sang LEE, Sang-Bo LEE, Jin-Kyung LEE, Sun-Tae JUNG, Young-Gu JIN
